Abstract

Aims: This study to evaluate the efficacy and complications of Argon Plasma Coagulation (APC) therapy to treat post-RYGB weight regain compared to a sham control group. Methods: 41 Patients with minimum regain of 10 kg and minimal postoperative time of 36 months was randomized into two groups. Results: In the APC group (n=21), the mean initial weight 100.4 kg, and mean regained weight of 24.94 kg. In the Sham group (n=20), the mean initial weight of 103.65 kg, and mean regained weight of 25.18 kg. Only happened anastomosis stenosis after the first APC session. The comparative results between the APC versus the Sham were percentage recovered weight loss (63.95 x-2.65), weight loss in kg (15.02 x-0.57), percentage total weight loss (14.46 x-0.62), % excess weight loss (54.32 x-2.34), and BMI reduction (5.38 x-0.21), with a p<0.0001 for all the comparisons. There was a significant reduction in the APC group of HbA1c (5.66% to 4.96%) and triglycerides (153.20mg/dL to 132.20mg/dL). Conclusion: This study proves that APC outlet pouch reduction is much superior compared to sham in promoting weight loss for patients that presented weight regain after de RYGB.
