Resectional gastric bypass is a new alternative in morbid obesity

Severe obesity is a common serious health problem in the United States. Medical therapy is often ineffective. A variety of surgical procedures have been employed for treatment of morbid obesity. Surgical therapy continues to evolve.

Eighty-five patients have undergone subtotal gastrectomy and retrocolic Roux-en-Y gastrojejunostomy for weight control at our institution. We refer to this procedure as resectional gastric bypass (RGB). Thirty-eight patients have undergone RGB as conversion from failed or problematic prior bariatric procedures. Forty-seven patients have had RGB as their primary bariatric procedure.

Twenty-six patients undergoing RGB for conversion of an anatomically or functionally failed prior bariatric procedure have had mean additional weight loss of 37% excess body weight (EBWL) in 18 months follow-up. Twelve patients undergoing RGB for intractable side effects of prior bariatric procedures have all had clinical improvement. Forty-seven patients undergoing RGB as a primary procedure have had EBWL of 53%, in mean follow-up of 11 months. For the entire series, major complications were one anastomotic leak, one reexploration for suspected subphrenic abscess, and one major pulmonary embolus. These patients recovered. There was no mortality in the series.

Resectional gastric bypass is a new alternative for salvage of a failed or problematic prior bariatric procedure. It is also effective as a primary weight control operation.
