Gastric Bypass Trumps Gastric Banding in Morbidly Obese

Bypass is safer, more effective than banding in patients with BMI above 50

MONDAY, July 17 (HealthDay News) -- While it may take longer and require a lengthier hospital stay, laparoscopic Roux-en-Y gastric bypass is safer and more effective than laparoscopic adjustable gastric banding among super morbidly obese patients, according to a study in the July issue of the Archives of Surgery.

Wilbur B. Bowne, M.D., of the State University of New York Health Science Center at Brooklyn, and colleagues compared the outcomes of the two bariatric surgeries among 106 super morbidly obese patients (body mass index, or BMI, of greater than 50). Sixty patients underwent gastric banding and 46 underwent gastric bypass between February 2001 and June 2004.

The investigators found that 78 percent of the patients who underwent the gastric banding procedure experienced late complications versus 28 percent of patients who underwent bypass. Gastric bypass patients, on average, had a BMI decrease of 26.5, compared with a BMI decrease of 9.8 among these who underwent the banding procedure. The bypass patients also reported being more satisfied with their procedure. All patients reported fewer comorbities after surgery, but the decrease was more pronounced in bypass patients, the report indicates.

"Laparoscopic Roux-en-Y gastric bypass appears superior to laparoscopic adjustable gastric banding in super morbidly obese patients," the study authors conclude.
