Long-term Comparative Evaluation of Weight Loss and Complications of Banded and Non-banded Roux-en-Y Gastric Bypass.

Purpose: The use of a nonadjustable silicone band around the gastric pouch of Roux-en-Y gastric bypass (RYGB) to reduce the recurrence of obesity is still being debated in the literature. The primary objective of this study was to evaluate banded and non-banded RYGB regarding % total weight loss (%TWL) and complications up to 10 years postoperatively and regarding the removal rate of the silicone band.

Material And Methods: A retrospective study of the medical records of all patients submitted to banded and non-banded RYGB between 2000 and 2020 was conducted.
