Effectiveness of argon plasma coagulation in the treatment of weight regain after roux-y gastric bypass: a cross-sectional prospective observational study

Introduction: Roux-en-Y Gastric Bypass (RYGB) is one of the most commonly performed surgeries to treat obesity worldwide. However, approximately 20% of patients have a recurrence of obesity, and enlargement of the gastrojejunal anastomosis is one of the associated factors. Endoscopic treatment of anastomosis has been proposed for further weight loss. One of the most commonly used techniques for anastomotic narrowing is argon plasma coagulation (APC). However, no randomized controlled trials have proven that this technique is superior to multidisciplinary follow-up. Objective: To evaluate and investigate the efficacy and safety of the application of argon plasma in the gastrojejunal anastomosis in the relapse of obesity after Gastric Bypass. Methods: Transversal study. Thirty-two patients were selected. More than 50% of The excess body weight regained was lost. Ranging from 6 to 25 kg. Results: A loss of more than 50% of the excess weight regained was observed in 30 % patients. Ranging from 6 to 25 kg. Conclusion: The application of argon plasma coagulation was safe and effective in the treatment of obesity recurrence after gastric bypass.
