Laparoscopic Roux-en-Y Gastric Bypass in Patients with Body Mass Index > 70kg/m2

Introduction: There is sparse literature regarding the optimal surgical management of megaobesity, defined as body mass index (BMI) >70 kg/m2. The purpose of this study was to compare laparoscopic Roux-en-y gastric bypass (LRYGP) and open Roux-en-y gastric bypass (ORYGP) in megaobese patients.
Methods: A retrospective review of patients with BMI >70 kg/m2 undergoing LRYGB and ORYGP from January 2003 to May 2007 at a single university comprehensive weight loss program was carried out. We reviewed preoperative demographics, operative details, postoperative course, and weight loss.
Results: Eighty-nine patients were reviewed. There were 52 ORYGP performed and 37 intended LRYGP with 3 conversions to open. There were no statistically significant demographic differences between these two groups regarding mean age (41 vs. 44 years), gender distribution (38% vs. 29% male), or initial BMI (80 kg/m2 vs. 77 kg/m2). There were no significant differences regarding incidence of pre-operative comorbidities including hypertension, diabetes mellitus, obstructive sleep apnea, gastroesophageal reflux disease, or osteoarthritis. Mean intra-operative blood loss was lower in the LRYGP group at 54 mL vs. 211 mL (p
