摘要

AIM To describe a modified technique of deployment of stents using the overtube developed for balloonassisted enteroscopy in post-sleeve gastrectomy(SG) complications. METHODS Between January 2010 and December 2015, all patients submitted to an endoscopic stenting procedure to treat a post-SG stenosis or leakage were retrospectively collected. Procedures from patients in which the stent was deployed using the balloon-overtube-assisted modified over-the-wire(OTW) stenting technique were described. The technical success, corresponding to proper placement of the stent in the stomach resulting in exclusion of the SG leak or the stenosis, was evaluated. Complications related to stenting were also reported.RESULTS Five procedures were included to treat 2 staple line leaks and 3 stenoses. Two types of stents were used, including a fully covered self-expandable metal stent designed for the SG anatomy(Hanarostent, ECBB-30-240-090; M.I. Tech, Co., Ltd, Seoul, SouthKorea) in 4 procedures and a biodegradable stent(BD stent 019-10A-25/20/25-080, SX-ELLA, Hradec Kralove, Czech Republic) in the remaining procedure. In all cases, an overtube was advanced with the endoscope through the SG to the duodenum. After placement of the guidewire and removal of the endoscope, the stent was easily advanced through the overtube. The overtube was pulled back and the stent was successfully deployed under fluoroscopic guidance. Technical success was achieved in all patients.CONCLUSION The adoption of a modified technique of deployment of OTW stents using an overtube may represent an effective option in the approach of SG complications.
