Background: Surgical management of the supersuper obese patient (BMI >60 kg/m2) has been a challenging problem associated with higher morbidity, mortality, and long-term weight loss failure. Current limited experience exists with a two-stage biliopancreatic diversion and duodenal switch in the supersuper obese patient, and we now present our early experience with a two-stage gastric bypass for these patients. Methods: We completed a retrospective bariatric database and chart review of super-super obese patients who underwent laparoscopic sleeve gastrectomy as a first-stage procedure followed by laparoscopic Roux-en-Y gastric bypass as a second-stage for more definitive treatment of obesity. Results: During a two-year period, 7 patients with BMI 58-71 kg/m2 underwent a two-stage laparoscopic Roux-en-Y gastric bypass by two surgeons at the Mount Sinai Medical Center. 3 patients were female, 4 patients were male, and the average age was 43. Prior to the sleeve gastrectomy, the mean weight was 181 kg with a BMI of 63. Average time between procedures was 11 months. Prior to the second-stage procedure, the mean weight was 145 kg with a BMI of 50 and average excess weight loss of 37 kg (33% EWL). Six patients have had follow-up after the second-stage procedure with an average of 2.5 months. At follow-up the mean weight was 126 kg with a BMI of 44 and average excess weight loss of 51 kg (46% EWL). The mean operative times for the two procedures were 124 and 158 minutes respectively. The average length of stay for all procedures was 2.7 days. 4 patients had 5 complications, which included splenic injury, proximal anastomotic stricture, left arm nerve praxia, trocar site hernia, and urinary tract infection.There were no mortalities in the series. Conclusions: Laparoscopic sleeve gastrectomy with second-stage Roux-en-Y gastric bypass are feasible and effective procedures based on short-term results. This two-stage approach is a reasonable alternative for surgical treatment of the high-risk supersuper obese patient.
