Combining laparoscopic adjustable gastric banding and biliopancreatic diversion after failed bariatric surgery.

Background: A percentage of all types of bariatric surgery will fail. Our experience with failed biliopancreatic diversion (BPD) as a primary operation or revision operation for failed laparoscopic adjustable gastric banding (LAGB) convinced us that uncontrolled hunger is often the underlying cause. To control hunger after failed bariatric surgery, a novel approach combining LAGB with BPD-duodenal switch (DS) has been tried. Methods: Patients who had failed to lose weight after BPD or LAGB were considered in 2 groups. Group 1: patients who had failed LAGB underwent laparoscopic BPD-DS without sleeve gastrectomy, with the LAGB left in-situ. Group 2: patients who had failed primary (subgroup 2a) or revision (subgroup 2b) BPD had a LAGB placed with no other revision of their surgery. Results: 11 patients have undergone this form of revision surgery with little morbidity. Mean age at the original operation was 45 years, mean (range) BMI was 45.3 (38-62) kg/m 2 . After the reoperation, at 3 months (9 patients) mean BMI was 30 kg/m 2 and at 6 months (4 patients) mean BMI was 27 kg/m 2 . Conclusion: In this small study, combination surgery was safe and effective for failed BPD or LAGB. LAGB failure may be best managed with DS malabsorption without gastric resection.
