Some Pre-Op Weight Loss Cuts Gastric Bypass Complications

Researchers advocate preoperative weight loss program, particularly for high-risk patients

THURSDAY, Dec. 24 (HealthDay News) -- Increased weight loss before gastric bypass surgery is associated with fewer complications after surgery, according to a study reported in the December issue of the Archives of Surgery.

Peter N. Benotti, M.D., of the Saint Francis Medical Center in Trenton, N.J., and colleagues reviewed medical records of 881 patients who underwent open or laparoscopic gastric bypass in 2002 to 2006 and who had participated in a six-month preoperative weight loss program consisting of medical, psychological, and nutritional evaluations, and patient education.

In univariate analysis, the researchers found that greater preoperative weight loss was associated with fewer total and major complications. Using a multiple logistic regression model controlling for sex, age, body mass index at baseline, and type of surgery, greater preoperative weight loss was found to be a predictor of reduced complications.

"In conclusion, this study suggests that preoperative weight loss may be associated with a reduced risk of surgical complications associated with bariatric surgery. We hope that these findings will be confirmed by prospective, controlled trials and that bariatric surgeons will consider this modality for preoperative risk reduction in selected patients who are deemed high risk for complications after surgery," the authors write.
