Résumé
BackgroundEarly postoperative small bowel obstruction (ESBO) following roux-en-Y gastric bypass (RYGB) is a feared complication, generally estimated to occur in 1-2% of cases. Most surgeons advocate for prompt surgical exploration for ESBO after RYGB. There is currently a paucity of literature regarding conservative management approaches to ESBO after RYGB.ObjectivesTo determine the safety and efficacy of non-operative management of early small bowel obstruction following RYGB.SettingAcademic-affiliated municipal hospital.MethodsWe performed a retrospective review of all patients at a single institution who underwent RYGB between July 1, 2020 and April 30, 2024 and were readmitted within 30 days of the procedure due to a small bowel obstruction. Mesenteric defects were closed with permanent suture in 100% of cases.Results2430 RYGBs were performed, 54 patients (2.2%) developed ESBO. The average interval from time of surgery to diagnosis of ESBO was 7.3 days [range 2-26 days]. The vast majority of patients (n = 43; 80%) were successfully managed conservatively including nasogastric decompression (n = 20; 47%). Most (73%) of the patients requiring reoperation were found to have kinking at the anastomosis or dense adhesions from the cut end of the staple line.ConclusionsThis study demonstrates that non-operative management may be a safe and effective treatment option for the majority of RYGB patients who develop ESBO. Clinical judgement is required to identify those who would benefit from early exploration.
