Biliopancreatic Diversion with Duodenal Switch Combined with Laparoscopic Adjustable Gastric Banding

Background: The authors investigated the usefulness of an approach combining biliopancreatic diversion (BPD) with duodenal switch (DS) and laparoscopic adjustable gastric banding (LAGB) in morbidly obese patients. Methods: 258 morbidly obese patients underwent bariatric surgery. 80 underwent gastric bypass (GBP), with an 80-ml pouch, a 120-150-cm common channel and a 350-cm alimentary limb (Group 1). 178 underwent BPD combined with DS-LAGB (Group 2): an 80cm common channel and a 200-cm alimentary limb were created in 68 patients (Subgroup 2a); a 120-cm common channel and a 300-cm alimentary limb were created in 110 patients (Subgroup 2b). Quality of life was assessed using the Moorehead-Ardelt Quality of Life Questionnaire (MA-QLQ). Results: At 2 years, mean BMI and %EWL were 27.8 kg/m² and 77.4 (Group 1), 25.2 kg/m² and 99.6 (Subgroup 2a), and 27.6 kg/m² and 79.3 (Subgroup 2b), respectively. 4 GBP patients regained their weight 2 years after surgery. There was 1 death, not related to surgery in Subgroup 2b. Preoperative MA-QLQ scores were similar between groups; at 2 years, MA-QLQ scores were higher in Subgroups 2a and 2b compared to Group 1 (+2.49 and +2.59 vs +0.98, respectively). Conclusion: Combination bariatric surgery is a safe, effective and durable weight loss option for the treatment of morbid obesity.
