- PURPOSE: The COVID-19 has had a profound impact on the health care delivery in Sweden, including deprioritization of benign surgeries during the COVID-19 pandemic. The aim of this study was to assess the effect of COVID-19 pandemic on emergency and planned hernia repair in Sweden.METHODS: Data on hernia repairs from January 2016 to December 2021 were retrieved from the Swedish Patient Register using procedural codes. Two groups were formed: COVID-19 group (January 2020-December 2021) and control group (January 2016-December 2019). Demographic data on mean age, gender, and type of hernia were collected.RESULTS: This study showed a weak negative correlation between the number of elective hernia repairs performed each month during the pandemic and the number of emergency repairs carried out during the following 3 months for inguinal hernia repair (p = 0.114) and incisional hernia repair (p = 0.193), whereas there was no correlation for femoral or umbilical hernia repairs.CONCLUSION: The COVID-19 pandemic had a great impact on planned hernia surgeries in Sweden, but our hypothesis that postponing planned repairs would increase the risk of emergency events was not supported.

- 2022
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 26:2, s. 635-646
-
Journal article (peer-reviewed)abstract
- Purpose: The aim of this study was to assess the feasibility and safety of a novel IPOM procedure with peritoneal bridging (IPOM-pb) for laparoscopic ventral hernia repair, and to compare the outcomes of this procedure with IPOM with- (IPOM-plus) and IPOM without (sIPOM) defect closure.Method: A single-centre retrospective study comparing a novel IPOM technique with peritoneal bridging (IPOM-pb) with the two commonly used IPOM techniques, IPOM with defect closure (IPOM-plus) and without defect closure (sIPOM). The intraoperative and postoperative data of patients who underwent laparoscopic IPOM ventral hernia repair were reviewed. Preoperative data, recurrence, and postoperative seroma, surgical site infection, and pain, were compared.Results: From January 2017 to June 2020, a total of 213 patients underwent laparoscopic ventral and incisional hernia repair with IPOM technique. The mean length and width of the ventral hernia was 4.4 +/- 1.8 cm and 3.6 +/- 1.4 cm, respectively, and the mean BMI was 30.1 +/- 5.2 kg/m(2). The mean operating time was 67 +/- 28 min and was longer for IPOM-pb (71 +/- 27 min), less for IPOM-plus (63 +/- 28 min), and least for sIPOM (61 +/- 26 min). The incidence of early postoperative seroma was least in IPOM-pb (1/98, 1%), and similar in the IPOM-plus (4/94, 4%) and sIPOM (1/21, 5%) group. Late postoperative seroma was found only in IPOM-plus (2, 2%). The incidence of early and late postoperative pain was relatively higher in sIPOM (3, 14%; 1, 5%, respectively) compared to IPOM-pb and IPOM-plus in the early (5, 5% and 6, 6%) and late (2, 2% and 1, 1%) postoperative period, respectively. Surgical site infection was higher in sIPOM group (3, 14%), compared to IPOM-pb (1, 1%), and IPOM-plus (3, 3%). Recurrence rates were similar in IPOM-pb group (3/98, 3%) and IPOM-plus (3/94, 3%), and none in sIPOM (0/21).Conclusion: IPOM with peritoneal bridging is as feasible and safe as conventional IPOM with defect closure and simple non-defect closure. However, a large randomised controlled trial is required to confirm this finding.

Location of recurrent groin hernias at TEP after Lichtenstein repair : a study based on the Swedish Hernia Register
- 2016
-
In: Hernia. - : Springer Science and Business Media LLC. - 1265-4906 .- 1248-9204. ; 20:3, s. 387-391

Journal article (peer-reviewed)abstract
- To investigate which type of hernia that has the highest risk of a recurrence after a primary Lichtenstein repair. Male patients operated on with a Lichtenstein repair for a primary direct or indirect inguinal hernia and with a TEP for a later recurrence, with both operations recorded in the Swedish Hernia Register (SHR), were included in the study. The study period was 1994-2014. Under the study period, 130,037 male patients with a primary indirect or direct inguinal hernia were operated on with a Lichtenstein repair. A second operation in the SHR was registered in 2236 of these patients (reoperation rate 1.7 %). TEP was the chosen operation in 737 in this latter cohort. The most likely location for a recurrence was the same as the primary location. If the recurrences change location from the primary place, we recognized that direct hernias had a RR of 1.51 to having a recurrent indirect hernia compared to having a direct recurrence after an indirect primary hernia repair. Recurrent hernias after Lichtenstein are more common on the same location as the primary one, compared to changing the location.

Full-thickness skin graft vs. synthetic mesh in the repair of giant incisional hernia : a randomized controlled multicenter study
- 2018
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; :2, s. 325-332
-
Journal article (peer-reviewed)abstract
- PURPOSE: Repair of large incisional hernias includes the implantation of a synthetic mesh, but this may lead to pain, stiffness, infection and enterocutaneous fistulae. Autologous full-thickness skin graft as on-lay reinforcement has been tested in eight high-risk patients in a proof-of-concept study, with satisfactory results. In this multicenter randomized study, the use of skin graft was compared to synthetic mesh in giant ventral hernia repair.METHODS: Non-smoking patients with a ventral hernia > 10 cm wide were randomized to repair using an on-lay autologous full-thickness skin graft or a synthetic mesh. The primary endpoint was surgical site complications during the first 3 months. A secondary endpoint was patient comfort. Fifty-three patients were included. Clinical evaluation was performed at a 3-month follow-up appointment.RESULTS: There were fewer patients in the skin graft group reporting discomfort: 3 (13%) vs. 12 (43%) (p = 0.016). Skin graft patients had less pain and a better general improvement. No difference was seen regarding seroma; 13 (54%) vs. 13 (46%), or subcutaneous wound infection; 5 (20%) vs. 7 (25%). One recurrence appeared in each group. Three patients in the skin graft group and two in the synthetic mesh group were admitted to the intensive care unit.CONCLUSION: No difference was seen for the primary endpoint short-term surgical complication. Full-thickness skin graft appears to be a reliable material for ventral hernia repair producing no more complications than when using synthetic mesh. Patients repaired with a skin graft have less subjective abdominal wall symptoms.

Long-term follow-up after elective adult umbilical hernia repair: low recurrence rates also after non-mesh repairs.
- 2013
-
In: Hernia : the journal of hernias and abdominal wall surgery. - : Springer Science and Business Media LLC. - 1248-9204. ; 17:4, s. 493-497
-
Journal article (peer-reviewed)abstract
- PURPOSE: The purpose of this study was to establish long-term outcome after elective adult umbilical hernia (AUH) repair. METHODS: Peri- and postoperative data considering all consecutive procedures at our institution during the time span from 1999 to 2009 were retrospectively gathered and followed by a questionnaire and, if needed, a clinical investigation in early 2011. RESULTS: A total of 162 patients (female/male 35%/65%) were operated, and 144/162 (89%) answers were gathered, mean follow-up time 70months; 77% were sutured, non-mesh repairs; 94% of all AUHs were smaller than 3cm; and 49% of the operations were performed under local anaesthesia. No perioperative complications were encountered. Five postoperative complications were encountered, two serious, both after mesh-based repairs. Wound infection rate (SSI) was low, 2/144 (1.4%). 7/144 (4.9%) recurrences were registered, none if mesh-based techniques were used, giving a recurrence rate of 6.3% in suture-based repairs, the difference, however, not statistically significant (p=0.141); 2% reported persistent pain at follow-up, 89% were overall satisfied with the outcome. CONCLUSIONS: AUH repair could be performed with low early and long-term complication rates, with low recurrence rates also after non-mesh repairs. A substantial cohort of patients will unnecessary be implanted with meshes if mesh-reinforced repairs should be used on a routine basis, that is, 16 surplus meshes to prevent one recurrence in the present study. We recommend a tailored approach to AUH repair: suture-based methods with defects smaller than 2cm and mesh-based repairs considered if larger than that.

Analysis of the abdominal musculo-aponeurotic anatomy in rectus diastasis : comparison of CT scanning and preoperative clinical assessment with direct measurement intraoperatively
- 2014
-
In: Hernia. - Paris : Springer. - 1265-4906 .- 1248-9204. ; 18:4, s. 465-471
-
Journal article (peer-reviewed)abstract
- PURPOSE: To evaluate and compare the consistency of agreement of two methods for measuring abdominal rectus diastasis (ARD), preoperative computed tomography (CT) scanning and preoperative clinical assessment were compared with direct measurement intraoperatively.METHODS: Fifty-five consecutive patients were retrieved from an ongoing prospective randomised trial comparing two operative techniques for the repair of ARD. All patients underwent a preoperative clinical assessment and CT scan, and the results were compared with intraoperative measurement of the ARD width. Agreement between methods was described with Bland-Altman plots (BA plots) and calculated using Lin's Concordance Correlation Coefficient (CCC).RESULTS: The median width of the diastasis was 4.0 cm in the upper midline and 3.0 cm in the lower midline for the intraoperative measurement. BA plots showed that measurements on CT and intraoperatively are not in agreement in the lower midline, whereas the agreement was stronger between the clinical and the intraoperative method. The CCC was higher for clinical vs. intraoperative measurement (0.479) than for CT vs. intraoperative measurement (-0.002) in the lower midline, although the agreement was over all low. CT scanning underestimated the width of the ARD when compared to 87 % of preoperative clinical assessments, and 83 % of intraoperative measurements. Preoperative clinical assessment overestimated ARD in 35 % when compared with intraoperative measurements.CONCLUSION: Clinical assessment prior to surgery provides more accurate information than CT scanning in the assessment of ARD width. CT scanning underestimates ARD width when compared with intraoperative measurement.

Assessment of abdominal muscle function using the Biodex System-4. Validity and reliability in healthy volunteers and patients with giant ventral hernia
- 2011
-
In: Hernia. - Paris : Springer. - 1265-4906 .- 1248-9204. ; 15:4, s. 417-421
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The decrease in recurrence rates in ventral hernia surgery have led to a redirection of focus towards other important patient-related endpoints. One such endpoint is abdominal wall function. The aim of the present study was to evaluate the reliability and external validity of abdominal wall strength measurement using the Biodex System-4 with a back abdomen unit.MATERIAL AND METHOD: Ten healthy volunteers and ten patients with ventral hernias exceeding 10 cm were recruited. Test-retest reliability, both with and without girdle, was evaluated by comparison of measurements at two test occasions 1 week apart. Reliability was calculated by the interclass correlation coefficients (ICC) method. Validity was evaluated by correlation with the well-established International Physical Activity Questionnaire (IPAQ) and a self-assessment of abdominal wall strength.RESULTS: One person in the healthy group was excluded after the first test due to neck problems following minor trauma. The reliability was excellent (>0.75), with ICC values between 0.92 and 0.97 for the different modalities tested. No differences were seen between testing with and without a girdle. Validity was also excellent both when calculated as correlation to self-assessment of abdominal wall strength, and to IPAQ, giving Kendall tau values of 0.51 and 0.47, respectively, and corresponding P values of 0.002 and 0.004.CONCLUSION: Measurement of abdominal muscle function using the Biodex System-4 is a reliable and valid method to assess this important patient-related endpoint. Further investigations will be made to explore the potential of this technique in the evaluation of the results of ventral hernia surgery, and to compare muscle function after different abdominal wall reconstruction techniques.

Mortality after elective and emergency surgery for inguinal and femoral hernia
- 1999
-
In: Hernia. - 1265-4906 .- 1248-9204. ; 3:4, s. 205-208
-
Journal article (peer-reviewed)abstract
- The aim of this study was to investigate mortality following elective and emergency groin hernia surgery. Information concerning 17 591 inguinal and 579 femoral hernia operations, including death of patients within 30 days of surgery, were prospectively recorded in the Swedish Hernia Register over a period of six years. Elective surgery for groin hernia is known to be a low-risk procedure. Mortality within 30 days of surgery was compared with the mortality of the general Swedish population using the standard mortality rate (SMR). Of all inguinal and femoral hernia repairs 5.1 % and 35.2 % respectively, were performed as an emergency. Following elective inguinal hernia repair the SMR for men fell significantly below unity. No significant differences between observed and expected mortality were observed following inguinal hernia surgery on females or following elective femoral hernia surgery on either gender. The reduced SMR found after elective hernia repair in men is most likely attributable to patient selection. After elective surgery on patients 70 years or older there is a tendency towards a reduction in SMR of the same order of size as for patients analysed as one group which, however, did not reach statistical significance. Mortality following both inguinal and femoral emergency procedures is increased five- to ten-fold compared to the 30-day mortality in the general population. A further increase in postoperative mortality is noted following emergency surgery with bowel resection.

Risk factors for reoperation due to chronic groin postherniorrhaphy pain
- 2015
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 19:6, s. 863-869
-
Journal article (peer-reviewed)abstract
- Chronic groin postherniorrhaphy pain (CGPP) is common and sometimes so severe that surgical treatment is necessary. The aim of this study was to identify risk factors for being reoperated due to CGPP. All 195,707 repairs registered in the Swedish Hernia Register between 1999 and 2011 were included in the study. Out of these, 28,947 repairs were excluded since they were registered as procedures on the same patient after a previous repair. Age, gender, hernia anatomy (indirect reference), method of repair (anterior sutured repair reference) and postoperative complications were included in a multivariate Cox analysis with reoperation due to CGPP as endpoint. Of the patients included in the study cohort, 218 (0.13 %) later underwent reoperation due to CGPP, including 31 (14 %) women. Median age at the primary repair was 61.5 years. Risk factors for being reoperated were age < median [hazard ratio (HR) 3.03, 95 % confidence interval (CI) 2.22-4.12], female gender (HR 2.13, CI 1.41-3.21), direct hernia (HR 1.35, CI 1.003-1.81), other hernia (HR 6.03, CI 3.08-11.79), Lichtenstein repair (HR 2.22, CI 1.16-4.25), plug repair (HR 3.93, CI 1.96-7.89), other repair (HR 2.58, CI 1.08-6.19), bilateral repair (HR 2.58, CI 1.43-4.66) and postoperative complication (HR 4.40, CI 3.25-5.96). Risk factors for being reoperated due to CGPP in this cohort included low age, female gender, a direct hernia, a previous Lichtenstein or plug repair, bilateral repair and postoperative complications. Further research on how to avoid CGPP and explore the effectiveness of surgery for CGPP is necessary.

Journal article (peer-reviewed)abstract
- Purpose The pathogenesis of groin hernia is not fully understood and some suggested risk factors are debatable. This population-based study evaluates the association between groin hernia repair and tobacco use. Method An observational study based on register linkage between the Swedish Hernia Register and the Vasterbotten Intervention Program (VIP). All primary groin hernia repairs performed from 2001 to 2013 in the county of Vasterbotten, Sweden, were included. Results VIP provided data on the use of tobacco in 102,857 individuals. Neither smoking nor the use of snus, increased the risk for requiring a groin hernia repair. On the contrary, heavy smoking decreased the risk for men, HR 0.75 (95% CI 0.58-0.96), as did having a BMI over 30 kg/m 2 HR (men) 0.33 (95% CI 0.27-0.40). Conclusion Tobacco use is not a risk factor for requiring a groin hernia repair, whereas having a low BMI significantly increases the risk.

Long-term follow-up of full-thickness skin grafting in giant incisional hernia repair : a randomised controlled trial
- 2022
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 26, s. 473-479
-
Journal article (peer-reviewed)abstract
- Purpose: Conventional repair of a giant incisional hernia often requires implantation of a synthetic mesh (SM). However, this surgical procedure can lead to discomfort, pain, and potentially serious complications. Full-thickness skin grafting (FTSG) could offer an alternative to SM, less prone to complications related to implantation of a foreign body in the abdominal wall. The aim of this study was to compare the use of FTSG to conventional SM in the repair of giant incisional hernia.Methods: Patients with a giant incisional hernia (> 10 cm width) were randomised to repair with either FTSG or SM. 3-month and 1-year follow-ups have already been reported. A clinical follow-up was performed 3 years after repair, assessing potential complications and recurrence. SF-36, EQ-5D and VHPQ questionnaires were answered at 3 years and an average of 9 years (long-term follow-up) after surgery to assess the impact of the intervention on quality-of-life (QoL).Results: Fifty-two patients were included. Five recurrences in the FTSG group and three in the SM group were noted at the clinical follow-up 3 years after surgery, but the difference was not significant (p = 0.313). No new procedure-related complication had occurred since the one-year follow-up. There were no relevant differences in QoL between the groups. However, there were significant improvemnts in both physical, emotional, and mental domains of the SF-36 questionnaire in both groups.Conclusion: The results of this long-term follow-up together with the results from previous follow-ups indicate that autologous FTSG as reinforcement in giant incisional hernia repair is an alternative to conventional repair with SM.

One-year outcome after repair of giant incisional hernia using synthetic mesh or full-thickness skin graft : a randomised controlled trial
- 2019
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 23:2, s. 355-361
-
Journal article (peer-reviewed)abstract
- PURPOSE: Repair of giant incisional hernia often requires complex surgery and the results of conventional methods using synthetic mesh as reinforcement are unsatisfactory, with high recurrence and complication rates. Our hypothesis was that full-thickness skin graft (FTSG) provides an alternative reinforcement material for giant incisional hernia repair and that outcome is improved. The aim of this study was to compare FTSG with conventional materials currently used as reinforcement in the repair of giant incisional hernia.METHODS: A prospective randomised controlled trial was conducted, comparing FTSG with synthetic mesh as reinforcement in the repair of giant (> 10 cm minimum width) incisional hernia. One-year follow-up included a blinded clinical examination by a surgeon and objective measurements of abdominal muscle strength using the Biodex-4 system.RESULTS: 52 patients were enrolled in the study: 24 received FTSG and 28 synthetic mesh. Four recurrences (7.7%) were found at 1-year follow-up, two in each group. There were no significant differences regarding pain, patient satisfaction or aesthetic outcome between the groups. Strength in the abdominal wall was not generally improved in the study population and there was no significant difference between the groups.CONCLUSION: The outcome of repair of giant incisional hernia using FTSG as reinforcement is comparable with repair using synthetic mesh. This suggests that FTSG may have a future place in giant incisional hernia repair.

Duration and magnitude of postoperative risk of venous thromboembolism after planned inguinal hernia repair in men : a population-based cohort study
- 2018
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 22:3, s. 447-453
-
Journal article (peer-reviewed)abstract
- Purpose: Little is known regarding the magnitude and timing of the risk of VTE following inguinal hernia surgery. We aimed to determine the absolute and relative rates of venous thromboembolism (VTE) following planned inguinal hernia repair.Methods: We analysed male adults with a first inguinal hernia repair with no prior record of VTE from the Clinical Practice Research Datalink, linked to the Hospital Episode Statistics (2001-2011). Crude rates and adjusted hazard ratios (HR) of the first VTE were calculated using Cox regression analysis to compare specific time periods following the surgery compared to the general population.Results: We identified 28,782 men who underwent an inguinal hernia repair with 53 (0.18%) having a first VTE in the 90 days following surgery. The overall rate of VTE in the first 90 days following surgery was 7.61 per 1000 person years (pyrs) (95% CI 5.82-9.96). Increasing age, a body mass index > 30 kg/m(2) and an in-patient procedure were associated with an increased risk of VTE, when compared to the general population. The risk of VTE was highest in the 1st month following the surgery with a 2.3- (aHR 2.33; 95% CI 1.09-4.99) and 3.5- (aHR 3.47; 95% CI 2.07-5.83) fold increased risk compared to the general population for both day case and planned in-patient procedures, respectively.Conclusions: Reassuringly, the absolute rates of VTE following inguinal hernia repair are low. Patients should be informed that their peak risk of VTE is during the 1st month following the surgery. Further studies on the optimum duration of thromboprophylaxis following surgery are required in high-risk patients undergoing hernia repair.

- Incisional hernia is a common problem after abdominal surgery. The complication and recurrence rates following the different repair techniques are a matter of great concern. Our aim was to study the results of incisional hernia repair in Sweden. A questionnaire was sent to all surgical departments in Sweden requesting data concerning incisional hernia repair performed during the year 2002. Eight hundred and sixty-nine incisional hernia repairs were reported from 40 hospitals. Specialist surgeons performed the repair in 782 (83.8%) patients. The incisional hernia was a recurrence in 148 (17.0%) patients. Thirty-three per cent of the hernias were subsequent to transverse, subcostal or muscle-splitting incisions or laparoscopic procedures. Suture repair was performed in 349 (40.2%) hernias. Onlay mesh repair was more common than a sublay technique. The rate of wound infection was 9.6% after suture repair and 8.1% after mesh repair. The recurrence rate was 29.1% with suture repair, 19.3% with onlay mesh repair, and 7.3% with sublay mesh repair. This survey revealed that there is room for improvement regarding the incisional hernia surgery in Sweden. Suture repair, with its unacceptable results, is common and mesh techniques employed may not be optimal. This study has led to the instigation of a national incisional hernia register.

Laparoscopic stoma formation with a prophylactic prosthetic mesh.
- 2010
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 14:5, s. 495-498
-
Journal article (peer-reviewed)abstract
- BACKGROUND: One year after stoma formation with an open technique, the rate of parastomal hernia is almost 50%. The herniation rate can be reduced to 10% with the use of a prophylactic mesh in a sublay position. For stomas formed with a laparoscopic technique, a surgical method with the use of prophylactic mesh should be sought. METHODS: Patients with a sigmoidostomy created with a laparoscopic technique were provided with a prophylactic large-pore, low-weight mesh in a sublay position. Follow-up examination was carried out after at least 12 months. RESULTS: Between March 2003 and May 2007, a sigmoidostomy was created in 25 patients. The patients' mean age was 65 years (range 31-89), the mean body mass index was 26 (range 21-32) and 15 were female. One stoma necrosis and two minor wound infections occurred. Parastomal hernia was present in 3 of 20 patients (15%) available for follow-up examination after 11-31 months (mean 19). No fistulas or strictures had developed. No mesh infection was noted and no mesh was removed. CONCLUSION: In laparoscopic stoma formation, a prophylactic large-pore, low-weight mesh in a sublay position is an easy and safe procedure associated with a low rate of parastomal hernia.

Different techniques for mesh application give the same abdominal muscle strength
- 2011
-
In: Hernia. - Paris : Springer. - 1265-4906 .- 1248-9204. ; 15:1, s. 65-68
-
Journal article (peer-reviewed)abstract
- PURPOSE: This study investigates abdominal muscle strength after surgery for giant hernia with the onlay, sublay or intraperitoneal (IPOM) method. Theoretically, placement of the mesh may result in different possibilities regarding function and postoperative physical activity related to abdominal muscle function.METHOD: Twenty-four patients operated for large ventral hernias using the onlay, sublay or IPOM technique were evaluated 1 year following surgery for abdominal wall strength using Biodex system 4.RESULTS: Despite the different surgical techniques used, no differences were observed in abdominal wall strength between the groups.CONCLUSION: The postoperative strength of abdominal wall muscles is independent of the method used for reconstruction of large abdominal wall hernia, and the choice of surgical technique should be directed by anatomical circumstances.

- INTRODUCTION: Parastomal hernia is a frequent complication after stoma formation. No consistent definition of parastomal hernia has been used in previous studies using clinical examination or computed tomography (CT) scan. The correlation between herniation rates found with clinical examination and CT scan has been poor. A definition of parastomal hernia with clinical examination that correlates with findings from CT scan should be sought.METHODS: Parastomal hernia, was with surgeons' clinical examination, defined as any protrusion in the vicinity of the stoma with the patient straining in a supine and an erect position. A new CT scan method was developed with the patient examined in the prone position. Radiologists defined herniation as any intra-abdominal content protruding beyond the peritoneum or the presence of a hernia sac. The correlation between investigators and methods were estimated by calculating Fleiss' Kappa values.RESULTS: Twenty-seven patients were assessed by three surgeons and three radiologists. For the surgeons, the Kappa value was 0.85. For the radiologists, it was 0.85 with CT scan in the prone position and 0.82 in the supine position. For the surgeons and radiologists collectively, the Kappa value was 0.80 for CT scan in the prone position and 0.63 in the supine position.CONCLUSION: With the new CT scan method examining patients in the prone position, the clinical and radiological definitions were highly reproducible and correlated strongly between methods and raters. With the strong correlation between clinical and radiological assessments, clinical examination alone is sufficient as follow-up. Conventional CT scan with the patient supine is not a reliable tool for diagnosing parastomal hernia.

Journal article (peer-reviewed)abstract
- Background: The aim of this study was to analyse the risk for reoperation following primary ventral hernia repair.Methods: The study was based on umbilical hernia and epigastric hernia repairs registered in the population-based Swedish National Patient Register (NPR) 2010-2019. Reoperation was defined as repeat repair after primary repair.Results: Altogether 29,360 umbilical hernia repairs and 6514 epigastric hernia repairs were identified. There were 624 reoperations registered following primary umbilical repair and 137 following primary epigastric repairs. In multivariable Cox proportional hazard analysis, the hazard ratio (HR) for reoperation was 0.292 (95% confidence interval (CI) 0.109-0.782) after open onlay mesh repair, 0.484 (CI 0.366-0.641) after open interstitial mesh repair, 0.382 (CI 0.238-0.613) after open sublay mesh repair, 0.453 (CI 0.169-1.212) after open intraperitoneal onlay mesh repair, 1.004 (CI 0.688-1.464) after laparoscopic repair, and 0.940 (CI 0.502-1.759) after other techniques, when compared to open suture repair as reference method. Following umbilical hernia repair, the risk for reoperation was also significantly higher for patients aged < 50 years (HR 1.669, CI 1.389-2.005), for women (HR 1.401, CI 1.186-1.655), and for patients with liver cirrhosis (HR 2.544, CI 1.049-6.170). For patients undergoing epigastric hernia repair, the only significant risk factor for reoperation was age < 50 years (HR 2.046, CI 1.337-3.130).Conclusions: All types of open mesh repair were associated with lower reoperation rates than open suture repair and laparoscopic repair. Female sex, young age and liver cirrhosis were risk factors for reoperation due to hernia recurrence, regardless of method.

- To compare clinical outcomes following sutureless Parietex (TM) ProGrip (TM) mesh repair to traditional Lichtenstein repair with lightweight polypropylene mesh secured with sutures. less thanbrgreater than less thanbrgreater thanThis is a 3-month interim report of a 1-year multicenter international study. Three hundred and two patients were randomized; 153 were treated with Lichtenstein repair (L group) and 149 with Parietex (TM) ProGrip (TM) precut mesh (P group) with or without fixation. The primary outcome measure was postoperative pain using the visual analog scale (VAS, 0-150 mm); other outcomes were assessed prior to surgery and up to 3 months postoperatively. less thanbrgreater than less thanbrgreater thanCompared to baseline, pain score was lower in the P group at discharge (-10%) and at 7 days (-13%), while pain increased in the L group at discharge (+39%) and at 7 days (+21%). The difference between groups was significant at both time points (P = 0.007 and P = 0.039, respectively). In the P group, patients without fixation suffered less pain compared to those with single-suture fixation (1 month: -20.9 vs. -6.15%, P = 0.02; 3 months: -24.3 vs. -7.7%, P = 0.01). The infection rate was significantly lower in the P group during the 3-month follow-up (2.0 vs. 7.2%, P = 0.032). Surgery duration was significantly shorter in the P group (32.4 vs. 39.1 min; P andlt; 0.001). No recurrence was observed at 3 months in both groups. less thanbrgreater than less thanbrgreater thanSurgery duration, early postoperative, pain and infection rates were significantly reduced with self-gripping polyester mesh compared to Lichtenstein repair with polypropylene mesh. The use of fixation increased postoperative pain in the P group. The absence of early recurrence highlights the gripping efficiency effect.

Analysis of outcome of Lichtenstein groin hernia repair by surgeons in training versus a specialized surgeon
- 2011
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 15:3, s. 281-288

Journal article (peer-reviewed)abstract
- Purpose: Groin hernia repair is a common procedure in general surgery, and is taught to and performed by surgeons early in their training. The aim of this observational study was to compare hernia repair performance and results of surgical trainees with those of a specialized surgeon. The further aim sought to identify what factors may influence short and long-term outcome, and areas for improvement in surgical training. Methods: A non-randomized parallel cohort study was designed to compare a specialized surgeon with surgical trainees, performing the Lichtenstein repair in adult males. Two hundred repairs were included, of which 96 were performed by surgical trainees. Patient characteristics, surgical experience, and operative data including duration of procedural parts and surgical complexity were noted at surgery. Postoperative complications, recurrence, chronic pain and residual symptoms were assessed at longterm follow-up after a median of 34.5 months. Results: Surgical trainees had longer overall operative time consume, with an unproportionally longer time for mobilising the sac and cord. They perceived exposure and mobilisation as more difficult than the specialist, and also a greater demand on own experience during surgery. The trainee repairs had a higher rate of postoperative complications (14.7% versus 5.0%) but recurrence rate was the same as for specialist repairs. At long-term follow-up, specialist repairs had a higher symptom burden and more chronic pain. Conclusions: Comparison of a specialized surgeon to surgical trainees in performance and outcome for inguinal hernia surgery shows it was more efficient, but not necessarily better to let a specialized surgeon perform the repairs. The better long-term outcome for surgical trainees stands in contrast to the prejudice that it is better to have an experienced surgeon to perform standard procedures. It seems likely that targeted training in dissection and mobilisation could decrease level of perceived complexity and shorten operative time consume for surgical trainees. We believe that adequately supervised hernia surgery should remain as a part of the surgical training.

Research review (peer-reviewed)abstract
- Introduction: The aim of the international CORE project was to explore the databases of the existing hernia registries and compare them in content and outcome variables. Methods: The CORE project was initiated with representatives from all established hernia registries (Danish Hernia Database, Swedish Hernia Registry, Herniamed, EuraHS, Club Hernie, EVEREG, AHSQC) in March 2015 in Berlin. The following categories were used to compare the registries: initiation and funding, data collection and use for certification of hernia centers, patient data and data protection, operative data, registration of complications and follow-up data. Results: The Danish Hernia Database is the only one to qualify as a genuine national registry where participation is compulsory for entry of all procedures by all surgeons performing a hernia operation. All other registries have to be considered as voluntary and completeness of data depends upon the participating hospitals and surgeons. Only the Danish Hernia Database and the Swedish Hernia Registry are publicly funded. All other registries are reliant on financial support from the medical technology industry. As an incentive for voluntary participation in a hernia registry, hospitals or surgeons are issued a certificate confirming that they are taking part in a quality assurance study for hernia surgery. Due to data protection and privacy regulations, most registries are obliged or have chosen to enter their patient data anonymously or coded. The Danish Hernia Database and Swedish Hernia Registry utilize a national personal patient code. In the Herniamed Registry, patient data are saved in a coded and anonymous format after obtaining the patient’s informed consent. Conclusion: Despite the differences in the way data are collected for each of the listed hernia registries, the data are indispensable in clinical research.

Treatment of de Garengeot's hernia : a meta-analysis
- 2019
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 23:1, s. 131-141

Research review (peer-reviewed)abstract
- Purposede Garengeot's hernia is a rare entity in which the appendix is located within a femoral hernia and is almost invariably encountered incarcerated in an emergency setting with concomitant appendicitis. In the literature, there are mostly single-case reports. The purpose of the present study was to perform a review of the literature to study the incidence, pathogenesis, demographics, clinical presentation, laboratory and radiological investigations, differential diagnosis, delay in diagnosis and treatment, operative findings, surgical technique, histological findings, the postoperative course, use of antibiotics, and complications regarding de Garengeot's hernia.MethodsA literature search was performed through PubMed with the following search terms, single or in combination: Garengeot, femoral hernia, and appendicitis. Additional references were also found within the articles, and two patients from Uppsala University Hospital were added.ResultsBetween 1981 and 2016, 70 publications were identified, and with the additional two patients, the present series comprised 90 patients There were 75 women (median age 73.0years) and 15 men (median age 78.0years). On examination, an inguinal mass was found in 87 patients (97%), which was painful and the cause of primary complaint in 67 patients (74%): the median duration of symptoms was 3days. Radiological investigations or ultrasound were performed in 67 patients (74%); computed tomography was the most accurate with a positive diagnosis in 23/34 patients. Appendicitis was found in 76 patients, gangrenous in 23, and perforated in 9. The surgical approach was inguinal in 76 patients, including 15 with concomitant laparotomy. The preperitoneal route was chosen in six patients, and laparoscopy alone in four patients. A mesh/plug was used in 22 patients (7/22 normal appendix) and suture repair in 59 (4/59 normal appendix: p<0.01). Complications were analysed in 79 patients and occurred in 11%. There was no mortality.Conclusionsde Garengeot's hernia is rare, being indistinguishable from an incarcerated femoral hernia in general. A delay in surgery should be avoided but if needed, computed tomography may be used for differential diagnosis. Although there is no standard treatment, mesh material does not appear advisable in the presence of a perforation, and it is beneficial for the surgeons to perform their routine method rather than a specific technique.

EHS clinical guidelines on the management of the abdominal wall in the context of the open or burst abdomen
- 2018
-
In: Hernia. - : Springer Science and Business Media LLC. - 1265-4906 .- 1248-9204. ; 22:6, s. 921-939
-
Research review (peer-reviewed)abstract
- Purpose: To provide guidelines for all surgical specialists who deal with the open abdomen (OA) or the burst abdomen (BA) in adult patients both on the methods used to close the musculofascial layers of the abdominal wall, and regarding possible materials to be used. Methods: The guidelines were developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach including publications up to January 2017. When RCTs were available, outcomes of interest were quantitatively synthesized by means of a conventional meta-analysis. When only observational studies were available, a meta-analysis of proportions was done. The guidelines were written using the AGREE II instrument. Results: For many of the Key Questions that were researched, there were no high quality studies available. While some strong recommendations could be made according to GRADE, the guidelines also contain good practice statements and clinical expertise guidance which are distinct from recommendations that have been formally categorized using GRADE. Recommendations: When considering the OA, dynamic closure techniques should be prioritized over the use of static closure techniques (strong recommendation). However, for techniques including suture closure, mesh reinforcement, component separation techniques and skin grafting, only clinical expertise guidance was provided. Considering the BA, a clinical expertise guidance statement was advised for dynamic closure techniques. Additionally, a clinical expertise guidance statement concerning suture closure and a good practice statement concerning mesh reinforcement during fascial closure were proposed. The role of advanced techniques such as component separation or relaxing incisions is questioned. In addition, the role of the abdominal girdle seems limited to very selected patients.

Reoperation for persistent pain after groin hernia surgery : a population-based study
- 2015
-
In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 19:1, s. 45-51
-
Journal article (peer-reviewed)abstract
- Purpose: The aim of the present study was to assess the outcome results after reoperation for persistent pain after hernia surgery in a population-based setting.Methods: All patients who had undergone surgery for persistent pain after previous groin hernia surgery 1999-2006 were identified in the Swedish Hernia Register (n = 237). Data on the surgical technique used were abstracted from the medical records. The patients were asked to answer a set of questions including SF-36 to evaluate the prevalence of pain after reoperation.Results: The study group consisted of 95 males and 16 females, mean age 53 years. In 27 % of cases an intervention aimed at suspected ilioinguinal neuralgia was performed. The mesh was removed completely in 28 % and partially in 13 %. A suture at the pubic tubercle was removed in 13 % of cases. Decrease in pain after the most recent reoperation was reported by 69 patients (62 %), no change in pain by 21 patients (19 %) and increase in pain in 21 patients (19 %). There was no significant difference in outcome between mesh removal, removal of sutures at the tubercle or interventions aimed at the ilioinguinal nerve. All subscales of SF-36 were significantly reduced when compared to the age-and gender-matched general population (p < 0.05).Conclusions: Patients reoperated for persistent pain after hernia surgery often report a reduction in pain, but the natural course of persistent pain, the relatively low response rate and selection of patients make it difficult to draw definite conclusions.

In: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 14:4, s. 341-344

Journal article (peer-reviewed)abstract
- PURPOSE: If the pathogeneses of the development of a recurrence varies following the different methods of hernia repair, the time required to develop a recurrence could be expected to vary. The aim of the study was to identify risk factors affecting the time interval between the primary repair and the reoperation.METHODS: Data from the Swedish Hernia Register were used. Each year of the 5-year follow-up period was treated as a separate subgroup and merged together into one large group. For each risk factor, we performed a Cox proportional hazard analysis, testing for interactions between the year and the risk factor, with reoperation as the endpoint.RESULTS: Altogether, 142,578 repairs were recorded, of which 7.7% were performed on women. The mean age of the cohort was 59 years. The overall recurrence rate in the 5-year period was 4.3%. Multivariate analysis showed that recurrence following surgery for recurrent hernia occurred relatively early (P < 0.05).Recurrence also appeared early if postoperative complications were registered (P < 0.05). Recurrence after suture repair or laparoscopic repair appeared relatively early compared to recurrence following open mesh repair (P < 0.05). In a separate analysis, a relatively higher risk for early recurrence was seen for all sutured repairs compared to all mesh repairs (P < 0.05).CONCLUSIONS: The pathogenesis behind the development of recurrence probably differs depending on the technique applied during the hernia repair. The higher proportion of early recurrences following laparoscopic repair, suture repair and recurrent repair may be explained by the high proportion of technical failures.

Journal article (peer-reviewed)abstract
- Introduction: The aim of this study was to evaluate the association between parity and the incidence rate of groin hernia repair in women.Method: This study was based on two Swedish national registers, the Medical Birth Register (MBR), and the Swedish Hernia Register (SHR). The cohort constituted of women born between 1956 and 1983. Data on vaginal and cesarean deliveries were retrieved from the MBR. The birth and hernia registers were cross matched to identify hernia repairs carried out after deliveries.Results: A total of 1,535,379 women were born between 1956 and 1983. Among these, 1,417,237 (92.3%) were registered for at least one birth. The incidence rate for Inguinal Hernia Repair (IHR) and Femoral Hernia Repair (FHR) was 10.7 per 100,000 person-year and 2.6 per 100,000 person-year, respectively. Compared with women registered for one delivery, the incidence rate ratio for IHR was 1.31 (95% Confidence Interval: 1.23–1.40) among women registered for two deliveries, 1.70 (1.58–1.82) among women registered for ≥ 3 deliveries. Additionally, the incidence rate ratios were higher 1.30 (1.14–1.49) and 1.70 (1.49–1.95) for FHR among women with two and ≥ 3 registered deliveries, respectively.Conclusion: In the present cohort, higher parity was associated with a higher incidence of inguinal as well as FHRs.

Risk factors for wound complications in midline abdominal incisions related to the size of stitches
- 2011
-
In: Hernia. - : Springer Science and Business Media LLC. - 1265-4906 .- 1248-9204. ; 15:3, s. 261-266
-
Journal article (peer-reviewed)abstract
- BACKGROUND: Midline abdominal incisions should be closed continuously with a suture length (SL) to wound length (WL) ratio above 4 using small stitches. The effect on the rate of wound complications of a very high ratio and other potential risk factors when closure is performed with small stitches is unknown. METHODS: Patients operated on through a midline incision were randomised to closure with small stitches, placed 5-8 mm from the wound edge and less than 5 mm apart, or with large stitches, placed more than 1 cm from the wound edge. Patient and operative variables were registered. Surgical site infection and incisional hernia were recorded. RESULTS: Three hundred and twenty-one patients were randomised to closure with small stitches and 370 with large stitches. Infection and herniation were less common with small stitches. With small stitches, no risk factors for infection or herniation were identified. With large stitches, wound contamination and the patient being diabetic were independent risk factors for infection, and long operation time and surgical site infection were risk factors for herniation. A very high SL to WL ratio did not affect the complication rates. CONCLUSIONS: In midline abdominal incisions closed with small stitches, no risk factors for surgical site infection or incisional hernia were identified. Increasing the ratio very much above 4 had no adverse effects on the rate of wound complications. The higher rates of infection and herniation with an SL to WL ratio over 5 and in overweight patients in previous reports were probably related to wounds being closed with large stitches.
