Emergency Endoscopy for Gastrointestinal Bleeding After Bariatric Surgery. Therapeutic Algorithm

Abstract

ObjectiveGastrointestinal bleeding (GB) is a potential complication after bariatric surgery and its frequency is around 2–4% according to the literature. The aim of this study is to present our experience with GB after bariatric surgery, its presentation and possible treatment options by means of an algorithm. Patients and methodFrom January 2004 to December 2012, we performed 300 consecutive laparoscopic bariatric surgeries. A total of 280 patients underwent a laparoscopic Roux en Y gastric bypass with creation of a gastrojejunal anastomosis using a circular stapler type CEAA No 21 in 265 patients and with a linear stapler in 15 patients. Demographics, clinical presentation, diagnostic evaluation and treatment were reviewed. A total of 20 patients underwent a sleeve gastrectomy. ResultsTwenty-seven cases (9%) developed GB. Diagnosis and therapeutic endoscopy was required in 13 patients. The onset of bleeding occurred between the 1st–6th postop days in 10 patients, and the origin was at the gastrojejunostomy staple-lines, and 3 patients had bleeding from an anastomotic ulcer 15–20 days after surgery. All other patients were managed non-operatively. ConclusionConservative management of gastrointestinal bleeding is effective in most cases, but endoscopy with therapeutic intent should be considered in patients with severe or recurrent bleeding. Multidisciplinary postoperative follow-up is very important for early detention and treatment of this complication.
