Laparoscopic sleeve gastrectomy (LSG) has been performed as a stand-alone primary bariatric procedure with increasing frequency. Staple line leakage is the most terrifying complication of the operation. In this study, three cases of proximal gastric leak after LSG treated by uncovered biodegradable polydioxanone stent under fluoroscopic and endoscopic guidance were analysed retrospectively. Endoscopic stenting is an efficacious minimally invasive method in the treatment of post-sleeve proximal gastric leaks and associated with rapid patient recovery and short hospital stay duration. Moreover, biodegradable stents are of major advantage with no need to be withdrawn.
