Abstract
AbstractBackgroundEmergency laparotomy is associated with a high morbidity and mortality rate. The decision on whether to perform an anastomosis or an enterostomy in emergency small bowel resection is guided by surgeon preference alone, and not evidence based. We examined the risks involved in small bowel resection and anastomosis in emergency surgery.MethodsA retrospective study from 2016 to 2019 in a university hospital in Denmark, including all emergency laparotomies, where small‐bowel resections, ileocecal resections, right hemicolectomies and extended right hemicolectomies where performed. Demographics, operative data, anastomosis or enterostomy, as well as postoperative complications were recorded. Primary outcome was the rate of bowel anastomosis. Secondary outcomes were the anastomotic leak rate, mortality and complication rates.ResultsDuring the 3.5‐year period, 370 patients underwent emergency bowel resection. Of these 313 (84.6%) received an anastomosis and 57 (15.4%) an enterostomy. The 30‐day mortality rate was 12.7% (10.2% in patients with anastomosis and 26.3% in patients with enterostomy). The overall anastomotic leak rate was 1.6%, for small‐bowel to colon 3.0% and for small‐bowel to small‐bowel 0.6%.ConclusionA primary anastomosis is performed in more than eight out of 10 patients in emergency small bowel resections and is associated with a very low rate of anastomotic leak.
