BackgroundData on laparoscopic bariatric surgery in the extremely obese are limited. Technical difficulties, in addition to the patients' severe weight-related co-morbidities, can compromise the safety of bariatric surgery in these patients. Our objectives were to assess the safety and feasibility of laparoscopic bariatric surgery in extremely obese patients and to compare the outcomes of different surgical approaches at a bariatric surgery center of excellence in an academic medical center.MethodsWe reviewed our prospectively collected database and identified all patients with a body mass index (BMI) of ≥ 70 kg/m(2) who had undergone bariatric surgery. The data on patient demographics, baseline characteristics, and outcomes of bariatric surgery were retrieved.ResultsA total of 49 patients with a mean BMI of 80.7 kg/m(2) (range 70-125) underwent 61 bariatric procedures. Of the 49 patients, 26 underwent sleeve gastrectomy, 11 gastric bypass, and 12 underwent a 2-stage procedure (sleeve gastrectomy followed by gastric bypass). At a mean follow-up of 17.4 months, the average BMI had decreased to 60.9 kg/m(2) (36% excess weight loss). Overall, the patients who underwent a 2-stage procedure achieved greater percentage of excess weight loss (54.5%) than did those who underwent either single-stage sleeve gastrectomy or gastric bypass (25.4%, P = .002 and 43.8%, P = .519, respectively). Of the 61 cases, 60 (98.4%) were completed laparoscopically. The early complication rate was 16.4% overall; most were minor complications. The late complication rate was 14.8%. A single late mortality occurred in this series.ConclusionLaparoscopic bariatric surgery can be performed safely on patients with a BMI of ≥ 70 kg/m(2). A staged approach might offer better weight loss results.Published by Elsevier Inc.
