Background
Roux-en-Y gastric bypass is one of the most widely performed bariatric surgeries. However, the relapse of obesity occurs in approximately 20% of patients and enlargement of the anastomosis is one of the factors associated with this relapse. Endoscopic treatment of the anastomosis has been proposed to assist in renewed weight loss. One endoscopic technique is the narrowing of the anastomosis argon plasma coagulation (APC). Objective: Evaluate the effectiveness and safety of the endoscopic treatment of an enlarged anastomosis with APC.
Methods
A randomized controlled study was conducted comparing APC to exclusive multidisciplinary management after weight regain.
Results
Forty-two patients were divided into two groups: APC (n = 22) and control (n = 20). After 14 months of follow-up with a crossover at 6 months, significant improvement in satiety and greater weight loss were found in the APC group and after crossover. APC was associated with significant weight loss [9.73 (7.46, 12) vs. + 1.38 (− 1.39, 2.15)], a reduction in the anastomosis diameter [p < 0.001], early satiation [0.77 (0.44, 1.11) vs. − 0.59 (− 0.95, − 0.23), p < 0.001], and increased quality of life measured using the EQ5D index [p = 0.04] and EQ5D VAS scale [p = 0.04]. Considering total mean weight loss throughout the entire follow-up, weight loss was similar in both groups (13.02 kg in the APC and 11.52 kg in the control).
Conclusion
Treatment of the gastrojejunal anastomosis with APC was effective and safe, with significant weight loss, the return of early satiation, and an improvement in quality of life.
