Singer Carnie Wilson, a founding member of pop group Wilson Phillips, has been open about her struggle with obesity for more than a decade, including a much-publicized decision to undergo gastric bypass surgery in 2000. In the years following surgery, Wilson had two children and, according to reports, regained more than 70 percent of her initial weight loss.
Band over bypass revision surgery is a new option available for patients who have previously had gastric bypass surgery that failed to result in significant weight loss, or for patients like Wilson, who have regained the weight they initially lost after bypass surgery.
“Although it’s uncommon, bariatric surgery patients can regain weight following an initially successful gastric bypass,” said Dr. Sunil Bhoyrul, a bariatric surgeon at Scripps Memorial Hospital La Jolla and a pioneer of the technique. "Over time, the stomach pouch created by the original bypass can dilate and cause patients to lose their sense of fullness,” he says, which leads to increased food intake and weight gain.
With band over bypass revision surgery, a gastric band is placed around the stomach pouch, then tightened to create physical restriction and restore the feeling of being full after a meal. Dr. Bhoyrul recently presented his technique to an audience of several hundred bariatric surgeons at an international conference in Hamburg, Germany.
Many times obesity surgeons like Dr. Bhoyrul will stitch the band in place to prevent slipping or movement that might cause the band to fail. Less invasive than a gastric bypass, the band over bypass procedure allows many patients to go home on the day of surgery.
Dr. Bhoyrul is medical director of the bariatric surgery program at Scripps Memorial Hospital La Jolla.
