Efficacy and safety of endoscopic treatment for anastomotic leakage following colorectal surgery: a systematic review

Objective

This study aims to synthesize relevant literature on endoscopic treatment of anastomotic leakage after colorectal surgery, and evaluate the safety and efficacy of endoscopic therapies including over-the-scope clip (OTSC), endoscopic vacuum therapy (EVT) and covered stent for anastomotic leakage (AL) following colorectal surgery, so as to provide evidence-based support for clinical decision-making.
