Not Applicable

Recruiting

• Conditions: Bariatric Surgery Candidate
• Interventions: Procedure: Argon plasma coagulation

• Registration Number: NCT05149105
• Lead Sponsor: Saint-Gregoire Private Hospital Center

Brief Summary

Among the techniques of bariatric surgery, the gastric Y bypass according to Roux (RYGB) allows greater weight loss and more lasting over time than sleeve gastrectomy and gastric banding. However, around 20% of patients will regain weight within 24 months after surgery. Among the many mechanisms that lead to weight regain, we can mention distension of the gastric pouch and gastro-jejunal anastomosis. A reoperation is then necessary. Argan plasma coagulation intervention (APC) by endoscopy allows to reduce the caliber of the gastro-jejunal anastomosis. The aim of the study is to show the efficacy of APC associated with multidisciplinary medical management and to compare it with multidisciplinary medical management alone in weight regain of patients.

Arm && Interventions

Group	Intervention	Description
APC intervention	Argon plasma coagulation	In addition to multidisciplinary care (standard care), patients benefit from an Argon Plasma Coagulation (APC) intervention at D0. The APC intervention should be repeted at Month 2 and Month 4.

Primary Outcome Measures

Name	Time	Method
Comparison of the percentage change (loss) in excess weight from Day 0 to Month 12 between the 2 arms	Day 0 (before the intervention) and Months 12 (one year after Day 0)	The percentage of excess weight loss (PEP%) will be measured according to the formula: PEP% = weight loss in kg \* 100 / excess of initial weight. The initial excess weight is defined as the baseline weight - ideal weight.
