Laparoscopic reoperative approach after open bariatric surgery.

The aim of the study was to evaluate the laparoscopic approach to reoperative bariatric surgery. From January 2003 to July 2007, 26 obesity surgery patients were referred to our Institution for revision. Nineteen patients previously had an open gastric banding, 3 an open vertical banded gastroplasty, 2 an open jejunoileal by-pass (J-l BP) and 2 an open gastric by-pass. Indications for re-operation were insufficient weight loss in 14 patients, band slippage in 7, band erosion in 3 and severe malabsorptive syndrome in 2. Mean preoperative BMI was 45 kg/m2. Twenty-six laparoscopic re-operative procedures were performed. Three patients required a third operation. Eleven gastric banding patients underwent band removal, 7 gastric banding patients were converted to an open gastric by-pass, 1 band was removed and simultaneously re-placed, the 2 jejuno-ileal by-pass patients underwent an intestinal restoration, 3 vertical banded gastroplasty patients were converted to laparoscopic gastric by-pass, 1 open gastric by-pass patient was converted to a laparoscopic long-limb gastric by-pass and in 1 patient with a gastro-gastric fistula after open gastric by-pass the fistula was resected. Further procedures included 1 laparoscopic gastric banding, 1 laparoscopic gastric bypass and 1 laparoscopic bilio-pancreatic diversion. Conversion to laparotomy was needed in 5 cases (5/29, 17.2%). Early complications included 1 case of pneumothorax and 6 cases of wound infection (24.1%). Mortality was zero. The mean follow-up was 36.2 months. Mean postoperative BMI was 34.3 kg/m2. Laparoscopic reoperative bariatric surgery is feasible, safe and effective after open bariatric surgery.
