In a report at the annual Digestive Disease Week in Chicago, researchers reported that patients receiving a repeated (or reoperative) bariatric surgery showed significant weight loss after one year, as well as low rates of associated illnesses and mortality.
Dr. Ranjan Sudan of Duke University led the study by members of the American Society of Metabolic and Bariatric Surgery. They analyzed over 28,000 bariatric surgery operations that were reoperations. Seventy percent of the cases were corrective procedures of the initial operation, while 30% comprised conversion procedures (conversion from the initial procedure to another).
At 30 days, the team found that the rate of serious adverse events for the initial and corrective surgeries was comparable and very low (approx. 1.6%). The conversion procedures had a higher rate of serious complications at 3.26%.
After one year, the rates of serious complications for the initial and reoperations had changed very little. Complications with the conversion surgeries had increased slightly to 3.61%.
The mortality rates after one year for the initial operations and the reoperations were comparable and quite low (less than 0.3%).
Researchers noted that patients who had received the reoperative bariatric operations showed an average 36% weight loss.
