Endoscopic options like primarily endoscopically placed fully covered self-expandable metallic stents (SEMS) offer significant benefits for the management of leaks and obstructions or stenosis, and even in case of mega stent failure, further endoscopic techniques could resolve the situation.
A mega stent is an effective and safe tool for the early management of post-bariatric surgery leakage and stenosis, and it is associated with acceptable rates of failure that can be managed by further endoscopic techniques in most of the patients.
