Background and study aims: Ring complications after a banded Roux-en-Y gastric bypass (RYGB) are usually managed surgically. The aim of this study was to analyze the safety and effectiveness of endoscopic removal of noneroded rings after banded-RYGB, by inducing intragastric erosion of the ring using a self-expandable plastic stent (SEPS).

Patients and methods: A total of 41 patients with banded RYGB who had noneroded rings and food intolerance were prospectively enrolled. Patients were treated with endoscopic SEPS placement and ring removal. Data from time of stenting, resolution of symptoms, need for endoscopic dilation, and complications were recorded.

Results: Successful ring removal was possible in all patients. In 21 cases, the SEPS induced complete erosion, and in 17 cases the ring was removed a month later because of incomplete erosion at the time of SEPS removal. Nine patients (22.0 %) needed endoscopic dilation after stent removal in order to treat fibrotic strictures. Food tolerance was observed in 32 patients (78.0 %) after the procedure. No patient needed surgery and there were no deaths.

Conclusions: Endoscopic removal of the ring using SEPS appeared to be safe and effective after a banded RYGB.
