- Purpose: Persistent fecal incontinence beyond childhood is common in ARM patients. The aim of this study was to analyze a consecutive series of adult patients with persistent incontinence, establish the causes, and evaluate whether further treatment could be offered. Methods: Forty-four adult ARM patients with reported incontinence were invited. Eighteen patients (11 males, median age 40.5 years, range 18-50 years) accepted and underwent clinical examination, rectoscopy, and 3D-ultrasound. Five had previously been treated with secondary surgery to improve continence. Results: Seventeen of the 18 patients had abnormal findings at examination. Eight patients had obstruction of the reconstructed anus. Eleven patients had sacral deformities. Nine patients had a defect in the external anal sphincter and nine patients could not contract the sphincter on demand. Five patients had significant prolapse of mucosa. In one patient, the neoanus was totally misplaced, one patient had a rectovaginal fistula, and one patient had short bowel syndrome due to several small bowel resections. Ten patients were offered conservative and five surgical treatment. Conclusions: This case series of adults shows that a majority of the patients can be offered further treatment. This indicates a need for structured follow-up of ARM patients into adulthood.

- Background/purpose: The short-term outcome of posterior sagittal anorectoplasty (PSARP) procedure has been reported to be better than after abdominoperineal or abdominosacroperineal (AP) procedures. This study aimed to investigate the long-term functional outcome and quality of life after PSARP in adulthood and compare with the outcome after AP procedures. Methods: Twenty-four patients operated with PSARP at the Department of Pediatric Surgery, Uppsala, Sweden, from 1984 to 1993 were identified. They were compared with 20 patients that underwent AP pull-through procedures from 1974 to 1983. The patients were sent validated bowel function and quality of life (SF-36) questionnaires. Sixteen PSARP (median age 21, five females) patients and fourteen AP patients (seven abdominosacroperineal and seven abdominoperineal pull-throughs, median age 32, seven females) responded and were included in the study. Results: The median Miller incontinence score was 1 (range 0-13) in the PSARP group and 10 (range 3-16) in the pull-through group (P = 0.0042). The use of underwear protection and oral loperamide was significantly less frequent in the PSARP group (P = 0.0096 and 0.0021 respectively). The SF-36 scores of Vitality, Mental health and Mental Cluster Scale were higher in the PSARP group (P = 0.0291, 0.0500, 0.0421 respectively). Conclusions: PSARP results in superior bowel function and better quality of life in adulthood compared with AP procedures for the repair of anorectal malformations.

- PURPOSE: NASHA Dx gel has been used extensively for treatments in the field of urology. This study was performed to evaluate NASHA Dx gel as an injectable anal canal implant for the treatment of fecal incontinence. METHODS: Thirty-four patients (5 males, 29 females; median age, 61 years; range, 34 to 80) were injected with 4 x 1 ml of NASHA Dx gel, just above the dentate line in the submucosal layer. The primary end point was change in the number of incontinence episodes and a treatment response was defined as a 50 percent reduction compared with pretreatment. All patients were followed up at 3, 6, and 12 months. RESULTS: The median number of incontinence episodes during four weeks was 22 (range, 2 to 77) before treatment, at 6 months it was 9 (range, 0 to 46), and at 12 months it was 10 (range, 0 to 70, P = 0.004). Fifteen patients (44 percent) were responders at 6 months, compared with 19 (56 percent) at 12 months. No long-term side effects or serious adverse events were reported. CONCLUSIONS: Submucosal injection of NASHA Dx gel is an effective treatment for fecal incontinence. The effect is sustained for at least 12 months. The treatment is associated with low morbidity.

- Background Coagulopathy after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) is recognized but few details have been studied.Objectives The aim of this study was to investigate changes in coagulation biomarkers and their predictive ability for venous thromboembolism (VTE).Methods Patients undergoing CRS and HIPEC at Uppsala University Hospital, Sweden, from 2004 to 2014 were included in a prospective study of coagulation biomarkers. Prothrombin time international normalized ratio (PT-INR), activated partial thromboplastin time (APTT), fibrinogen, antithrombin, D-dimer, and platelets were sampled on postoperative days 1, 2, 5, and 10. Logistic regression analysis was used to evaluate predictive capacity for coagulation-related complications.Results Overall, 380 patients were included (214 females, mean age 56 years); 38 patients had a history of thromboembolism and 57 were active smokers. Mean perioperative blood loss was 1228 mL and 231 (61%) received perioperative blood transfusions. PT-INR and APTT were elevated directly after surgery but returned to normal levels on postoperative day 5. Conversely, fibrinogen, platelet count, D-dimer, and antithrombin increased by postoperative day 5 and continued to increase up to day 10. There were 23 radiologically verified cases of VTE within 6 months. The multivariate analysis identified a completeness of cytoreduction score of 2-3 (p = 0.047) and day 2 D-dimer (p = 0.0082) as independent risk factors for postoperative VTE.Conclusion Significant postoperative changes in coagulation biomarkers occur with dynamic changes over 10 days postoperatively. The incidence of symptomatic VTE was low. Residual tumor at completion of surgery and elevated D-dimer on day 2 were independent risk factors for postoperative VTE.

HIPECology : Aspects of Postoperative Morbidity Following the HIPEC Procedure
- 2022

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Peritoneal surface malignancy (PM), regardless of the dissemination site, was once considered a terminal condition. However, the introduction of a surgical approach with cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) with or without early intraperitoneal chemotherapy (EPIC) shifted the attitude from managing the symptoms of PM to disease treatment with curative intent. The magnitude of this combined therapy leaves the patients at risk for a diverse range of postoperative morbidities. Moreover, some small cohort studies argued that combining HIPEC with EPIC is associated with a higher risk of postoperative complications compared to HIPEC alone. The overall aim of the thesis was to investigate postoperative morbidity following the management of PM with CRS and HIPEC ± EPIC.We investigated readmission morbidity within 6 months after CRS and HIPEC, using a national population-based register. The results of this study showed that morbidity causing HIPEC-related readmission was higher than expected, with almost half of the interventions occurring outside the HIPEC centre. Gastric resection and advanced age are independent predictors of morbidity and readmission. We analyzed postoperative coagulopathy and the risk for venous thromboembolic events (VTE) in a prospective study. Results revealed that significant postoperative changes in coagulation biomarkers occur with dynamic changes over 10 days postoperatively. The incidence of symptomatic VTE was low. Residual tumor at completion of surgery, and elevated D-dimer on day 2, were independent risk factors for postoperative VTE. Postoperative morbidity following HIPEC + EPIC was compared to morbidity following HIPEC alone in our propensity score matched study. Results showed that HIPEC + EPIC is associated with a prolonged hospital stay (LOS), but there was no statistically significant relevant increase in postoperative morbidity, reoperation rate or incidence of readmission. Finally, we also analyzed the impact of different strategies of intraoperative fluid management during CRS and HIPEC on postoperative outcomes. Goal-directed therapy (GDT) is associated with significantly improved LOS despite an increase in morbidity in some patients. GDT management does not affect the postoperative risk for hemorrhage, although the choice of an oxaliplatin-based HIPEC does. Personalized GDT based on patients’ characteristics and surgery should be utilized during the management of CRS and HIPEC patients.

- Background: Combining hyperthermic intraperitoneal chemotherapy (HIPEC) treatment with early postoperative intraperitoneal chemotherapy (EPIC) may increase postoperative morbidity. This study aims to investigate postoperative morbidity after HIPEC+EPIC compared with HIPEC alone in patients with peritoneal metastases (PM).Materials and methods: This is a retrospective propensity score matched cohort study. All patients undergoing PM treatment at Uppsala University Hospital between February 2004 and December 2014 were included. Propensity score matching with a 1:1 ratio was performed using sex, primary tumor site, preoperative chemotherapy, peritoneal cancer index, completeness of cytoreduction score, and HIPEC regimen. Length of hospital stay, morbidity, reoperation rate, and readmission rate within 6 months were selected as endpoints.Results: A total of 390 consecutive patients were divided in two arms: HIPEC+EPIC (n = 115) and HIPEC alone (n = 275). The propensity score matching (n = 190) was successful with balanced covariates: 95 patients/arm. The length of stay (LOS) was longer in the HIPEC + EPIC group in the total cohort (30 vs 24 days, p < 0.001), with a trend towards significance in the propensity matched group (29 vs 25 days, p = 0.062). No other differences in endpoints were found.Conclusion: HIPEC+EPIC is associated with a prolonged hospital stay, but with no statistically significant relevant increase in postoperative morbidity, reoperation rate or incidence of readmission.

- Background Comprehensive readmission morbidity studies after cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are scarce. This study aimed to investigate readmissions and in-hospital morbidity after CRS and HIPEC. Methods The national in-hospital patient register was used to identify patients via the HIPEC ICD code JAQ10 2004-2014. Data were retrieved from the index CRS/HIPEC treatment and from all HIPEC-related readmissions within 6 months. Univariate/multivariate logistical analyses were performed to identify risk factors for reinterventions and readmissions. Results A total of 519 patients (mean age 56 years) had a mean hospital stay of 27 days. Within 6 months, 150 readmissions for adverse events were observed in 129 patients (25%) with 67 patients requiring an intervention (13%). Totally 179 patients (34%) required a reintervention during the first 6 months with 85 (16%) requiring a reoperation. Of these 179 patients, 83 patients (46%) did not undergo the intervention at the HIPEC centre. Gastric resection was the only independent risk factor for in-hospital intervention, and advanced age for readmission. Conclusion Morbidity causing HIPEC-related readmission was higher than expected with almost half of the interventions occurring outside the HIPEC centre. Gastric resection and high age are independent predictors of morbidity and readmission.

- Background The impact of intraoperative fluid management during cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) on postoperative outcomes has been poorly investigated. This study aimed to investigate the impact of intraoperative fluid management strategy on postoperative outcomes and survival focusing on postoperative hemorrhage. Methods 509 patients undergoing CRS and HIPEC at Uppsala University Hospital/Sweden 2004-2017 were categorized into two groups according to the intraoperative fluid management strategy: pre-goal directed therapy (pre-GDT) and goal directed therapy (GDT), where a hemodynamic monitor (CardioQ or FloTrac/Vigileo) was used to optimize fluids management. Impact on morbidity, postoperative hemorrhage, length-of-stay and survival was analyzed. ResultsThe pre-GDT group received higher intraoperative fluid volume compared to the GDT group (mean 19.9 vs. 16.2 ml/kg/h, p<0.001). Overall postoperative morbidity Grade III-V was higher in the GDT group (30% vs. 22%, p=0.03). Multivariable adjusted odds ratio (OR) for Grade III-V morbidity was 1.80 (95%CI 1.10-3.10, p=0.02) in the GDT group. Numerically, more cases of postoperative hemorrhage were found in the GDT group (9% vs. 5%, p=0.09), but no correlation was observed in the multivariable analysis 1.37 (95%CI 0.64-2.95, p=0.40). An oxaliplatin regimen was a significant risk factor for postoperative hemorrhage (p=0.03). Mean length of stay was shorter in the GDT group (17 vs. 26 days, p<0.0001). Survival did not differ between the groups.ConclusionWhile GDT management increased the risk for postoperative morbidity, it was associated with shortened hospital stay. Intraoperative fluid management during CRS and HIPEC did not affect the postoperative risk for hemorrhage, while the use of an oxaliplatin regimen did.

- Background: Bariatric procedures are increasingly being used, but data on bowel habits are scarce.Objectives: To assess changes in gastrointestinal function and patient-scored symptoms after Roux-en-Y gastric bypass (RYGB) and biliopancreatic diversion with duodenal switch (BPD/DS).Setting: University hospital in Sweden.Methods: We recruited 268 adult patients (mean age of 42.5 yr, body mass index 44.8, 67.9% female) listed for RYGB and BPD/DS. Patients answered validated questionnaires prospectively concerning bowel function, the Fecal Incontinence Quality of Life Scale, and the 36-Item Short Form Health Survey before and after their operation.Results: Postoperatively, 208 patients (78.2% of 266 eligible patients) answered the questionnaires. RYGB patients had fewer bowel motions per week (8 versus 10) and more abdominal pain postoperatively (P<.001). Postoperatively, the 35 BPD/DS patients (69% versus 23%) needed to empty their bowel twice or more than twice daily, reported more flatus and urgency, and increased need for keeping a diet (P<.001). Concerning Fecal Incontinence Quality of Life Scale, coping and behavior was slightly reduced while depression and self-perception scores were improved after RYGB. Lifestyle, coping and behavior, and embarrassment were reduced after BPD/DS (P<.05). In the 36-Item Short Form Health Survey, physical scores were markedly improved, while mental scores were largely unaffected.Conclusion: RYGB resulted in a reduced number of bowel movements but increased problems with abdominal pain. In contrast, BPD/DS-patients reported higher frequency of bowel movements, more troubles with flatus and urgency, and increased need for keeping a diet. These symptoms affected quality of life negatively, however, general quality of life was markedly improved after both procedures. These results will be of great value for preoperative counseling.
