This is a retrospective study of prospectively collected data from 34 patients who had revisional bariatric surgery at a single centre. The aim was to report the indications for revisional surgery, operative time, conversion to open surgery, mortality, hospital stay, early and late complications, reoperations and short-term efficacy. From 2006 to 2011, 31 patients who formerly had been operated for morbid obesity with restrictive operations and 3 patients who had been operated in the upper abdomen for other morbidities (fundoplications 2, Heller's myotomy 1) underwent a revisional Roux-en-Y gastric bypass operation (n = 30) or sleeve gastrectomy (n = 4). Demographic data, perioperative characteristics and follow-up data were entered prospectively in the hospital's database for bariatric patients. Twenty-five operations were done by laparoscopic and nine by open technique. The mean operative time was 113.17 (33.98, 54-184) min. The mean postoperative hospital stay was 3.25 (5.71, 1-32) days. Intra-operative complications occurred in six patients (17.65%), postoperative complications in nine (26.47%), and major complications in three patients (8.82%), including leakage in the gastrojejunal anastomosis in two (5.88%) patients. The conversion rate to open surgery was 2.94% (one emergency patient). There was no mortality. Excess weight loss (%, ±SD) at 3 months follow-up averaged 42.31%, ±21.54. Revisional bariatric surgery can be performed with an increased but acceptable risk, with at least short-term weight loss comparable to primary operations.

That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.
Surgical procedure in which the STOMACH is transected high on the body. The resulting small proximal gastric pouch is joined to any parts of the SMALL INTESTINE by an end-to-side SURGICAL ANASTOMOSIS, depending on the amounts of intestinal surface being bypasses. This procedure is used frequently in the treatment of MORBID OBESITY by limiting the size of functional STOMACH, food intake, and food absorption.
