If you're one of the millions of overweight Americans and has been considering weight-loss surgery, the results of a new study comparing the safety and effectiveness of gastric bypass surgery and lap-band surgery may interest you. The study, titled "Better Weight Loss, Resolution of Diabetes, and Quality of Life for Laparoscopic Gastric Bypass vs. Banding," written by Guilherme M. Campos, M.D., et al. appeared in the February publication "Archives of Surgery."
The study's design was to match 100 pairs of people, one of whom had undergone the laparoscopic Roux-en-Y gastric bypass and the other the laparoscopic gastric banding surgery. The pairs were carefully matched so various criteria such as age, weight, sex, presence of Type 2 diabetes and body mass index were close to identical for the two people chosen for each pair.
This study measured outcomes during and after the surgical procedure, including a one-year period post-surgery. The measured outcomes included weight loss, quality of life and Type 2 diabetes resolution. Although many experts expected the outcomes to be more positive for those people who had had the gastric bandings performed, this study's conclusions demonstrated that the Roux-en-Y gastric bypass had a similar rate of overall complications as did the gastric banding, but fewer re-operations were needed with the gastric bypass.
Those people who had undergone gastric bypass surgery lost more weight in the year following surgery and showed a 76 percent resolution rate of Type 2 diabetes versus a 50 percent resolution rate in those who had gastric banding.
