- Introduction: Postoperative seroma and pain are common problems following laparoscopic intraperitoneal onlay mesh (IPOM) repair of ventral hernias. These advers outcomes may be avoided by dissecting and using the peritoneum in the hernial sac to bridge the hernia defect.Methods: This was a patient- an and outcome assesor-blinded, parallel-design, randomized controlled trial compairing nonclosure and peritoeal bridging approaches in patients schedueled for elective midline ventral hernia repair. The primary end point was seroma volume on ultrasonography. The secondary end points were postoperative pain, recurrence, and complications.Results: Between November 2018 and December 2020, 112 patients were randomized of whom 60 were in the nonclosure group and 52 were in the peritoneal bridging group. The seroma volume in the nonclosure and peritoneal bridging groups were 17cm3(6-53cm3) versus 0cm3(0-26cm3) at 1-moth follow-up (P=0.013). The median volume was zero at 3-, 6-, and 12-month follow-ups in both groups. No significant differences were observed in early postoperative pain (P=0.447) and in recurrencerate (P=0.684). There were 4(7%) and 1(2%) perioperative complictions that lead to reoperations in simple IPOM(sIPOM) and IPOM with peritoneal bridging (IPOM-pb), respectively.Conclusion: Seroma was less prevalent after IPOM-pb at 1-month follow-up compaired with sIPOM, with simillar posoperative pain 1 week after index of surgery in both groups. At subsequent follow-ups, the differences in seroma were not statiscally significant. Further studies are required to confirm these results.

Tidskriftsartikel (refereegranskat)abstract
- Objective: This study aimed to explore a possible relationship between preoperative biliary drainage (PBD) and overall survival in a national cohort of Swedish patients who underwent pancreaticoduodenectomy (PD) for pancreatic ductal adenocarcinoma (PDAC). Background: PBD has been shown to increase postoperative complications after PD, but its use is steadily increasing. There are a few small studies that have indicated that PBD might in itself negatively affect overall survival after PD. Methods: Patients from the Swedish National Registry for tumors in the pancreatic and periampullary region diagnosed from 2010 to 2019 who underwent PD for PDAC were included. Kaplan-Meier curves, log-rank tests and Cox proportional hazards analyses were performed to investigate survival. Results: Out of 15,818 patients in the registry, 3113 had undergone PD, of whom 1471 had a histopathological diagnosis of PDAC. Patients who had undergone PBD had significantly worse survival, but the effect of PBD disappeared in the multivariable analysis when elevated bilirubin at any time was included. Conclusions: PBD does not independently influence survival after PD for PDAC, but this study implies that even a nominally increased preoperative bilirubin level might impair long-term survival.

There Is No Increase in Perioperative Mortality After Pancreaticoduodenectomy in Octogenarians : Results From the Swedish National Registry for Tumors in the Pancreatic and Periampullary Region

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this observational study was to compare postoperative mortality and complications between octogenarians and younger patients following pancreaticoduodenectomy (PD).Summary Background Data: With the growing elderly population and improved operative and postoperative results, PD is performed more frequently in octogenarians. Despite recent studies, it is uncertain whether elderly patients experience worse postoperative outcomes than younger patients.Methods: All patients registered in the Swedish National Registry for tumors in the pancreatic and periampullary region from 2010 to 2018 who underwent PD were included in the analysis.Results: Out of 13,936 patients included in the registry, 2793 patients underwent PD and were divided into the following age groups: <70 (n = 1508), 70–79 (n = 1137), and ≥80 (n = 148) years old. There was no significant difference in in-hospital, 30- or 90-day mortality among groups. The 2 older groups had a higher rate of medical and some surgical complications but not a significantly higher rate of complications ≥IIIa according to the Clavien-Dindo classification system. The 2 older groups had lower body mass index, higher American Society of Anesthesiologists and Eastern Cooperative Oncology Group scores, lower smoking rates, and a higher rate of preoperative biliary drainage than the <70-year-old group (all P < 0.001). The operation time was shorter in the oldest group.Conclusions: Despite the worse preoperative condition of octogenarians than younger patients, short-term mortality and serious complications were not increased. The shorter operation time, however, may indicate that patients in the oldest group were more strictly selected. With careful preoperative consideration, especially regarding cardiovascular morbidity, more octogenarians can potentially be safely offered PD.

Benefit of Primary Tumor Resection in Stage IV, Grade 1 and 2, Pancreatic Neuroendocrine Tumors : A Propensity-Score Matched Cohort Study

Tidskriftsartikel (refereegranskat)abstract
- Objective: To determine the association of primary tumor resection in stage IV pancreatic neuroendocrine tumors (Pan-NET) and survival in a propensity-score matched study.Background: Pan-NET are often diagnosed with stage IV disease. The oncologic benefit from primary tumor resection in this scenario is debated and previous studies show contradictory results.Methods: Patients from 3 tertiary referral centers from January 1, 1985, through December 31, 2019: Uppsala University Hospital (Uppsala, Sweden), Sahlgrenska University Hospital (Gothenburg, Sweden), and Brigham and Women’s Hospital/Dana-Farber Cancer Institute (Boston, USA) were assessed for eligibility. Patients with sporadic, grade 1 and 2, stage IV pan-NET, with baseline 2000–2019 were divided between those undergoing primary tumor resection combined with oncologic treatment (surgery group [SG]), and those who received oncologic treatment without primary tumor resection (non-SG). A propensity-score matching was performed to account for the variability in the extent of metastatic disease and comorbidity. Primary outcome was overall survival.Results: Patients with stage IV Pan-NET (n = 733) were assessed for eligibility, 194 were included. Patients were divided into a SG (n = 65) and a non-SG (n = 129). Two isonumerical groups with 50 patients in each group remained after propensity-score matching. The 5-year survival was 65.4% (95% CI, 51.5-79.3) in the matched SG and 47.8% (95% CI, 30.6-65.0) in the matched non-SG (log-rank, P = 0.043).Conclusions: Resection of the primary tumor in patients with stage IV Pan-NET and G1/G2 grade was associated with prolonged overall survival compared to nonoperative management. A surgically aggressive regime should be considered where resection is not contraindicated.

Positive Expiratory Pressure Therapy on Oxygen Saturation and Ventilation After Abdominal Surgery : A Randomized Controlled Trial
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Objective: To evaluate the immediate effects of positive expiratory pressure therapy on oxygen saturation and ventilation after abdominal surgery.Background: Positive expiratory pressure therapy to treat postoperative hypoxia is widespread, despite a lack of evidence of effect.Methods: This randomized, sham-controlled, crossover trial investigated adults 1–2 days after abdominal surgery at Umeå University Hospital, Sweden. The intervention was positive expiratory pressure of 10–15 cm H2O. The control was a sham device. The investigations were ended with deep-breathing maneuvers. Outcomes were the gradient of changes in peripheral oxygen saturation and transcutaneous carbon-dioxide partial pressure (PtcCO2).Results: Eighty patients were included and randomized and 76 patients were analyzed. Oxygen saturation increased from a baseline mean of 92% to 95%, P < 0.001, during positive expiratory pressure breathing, while PtcCO2 decreased from a mean of 36 to 33 mm Hg, P < 0.001. This was followed by apnea, oxygen desaturations to a mean of 89%, P < 0.001, and increased PtcCO2 before returning to baseline values. The changes in oxygen saturation and PtcCO2 did not differ from sham breathing or deep-breathing maneuvers.Conclusions: Positive expiratory pressure breathing after abdominal surgery improves oxygen saturation during the maneuver because of hyperventilation, but it is followed by apnea, hypoventilation, and oxygen desaturation. The effect is not different from the expiration to a sham device or hyperventilation. It is time to stop positive expiratory pressure therapy after abdominal surgery, as there is no evidence of effect in previous trials, apart from the adverse effects reported here.
