Duodenal Switch Conversion in Non-responders or Weight Recurrence Patients

Area of Science:

• Bariatric surgery outcomes
• Surgical revisions and salvage procedures
• Metabolic and bariatric surgery

Background:

• Insufficient weight loss and weight regain are common challenges after bariatric surgery.
• Various surgical modalities exist, but their efficacy as salvage procedures varies.
• Duodenal switch conversion is explored as a potential solution for persistent weight issues.

Purpose of the Study:

• To evaluate the efficacy of duodenal switch conversion as a salvage procedure.
• To assess the safety profile of duodenal switch conversion.
• To compare weight loss outcomes and complication rates with primary bariatric procedures.

Main Methods:

• Retrospective study of 50 patients undergoing duodenal switch conversion.
• Comparison of excess weight loss and total body weight loss percentages pre- and post-conversion.
• Analysis of complication, emergency department visit, readmission, reoperation, and mortality rates.

Main Results:

• Duodenal switch conversion demonstrated statistically significant superiority in weight loss at 6, 12, and 24 months (p < 0.05).
• Mean operative times varied by primary procedure (146-208 min), with a mean length of stay of 3.38 days.
• Overall complication rate was 18%, with low rates for emergency visits (6%), readmissions (12%), and reoperations (10%); no mortality was recorded.

Conclusions:

• Duodenal switch conversion is an effective salvage procedure for insufficient weight loss or weight regain.
• The procedure is safe, with low rates of readmission, reoperation, and mortality.
• It offers a successful revision option following adjustable gastric band, sleeve gastrectomy, and Roux-en-Y gastric bypass.
