Effect of prophylactic closure on adverse events after colorectal endoscopic submucosal dissection: A meta‐analysis

Endoscopic submucosal dissection (ESD) has a high en bloc resection rate and is widely performed for large colorectal lesions. However, colorectal ESD is associated with a high frequency of adverse events (AEs), and the efficacy of prophylactic endoscopic closure after ESD for preventing AEs is still controversial. This meta‐analysis was conducted to assess the efficacy of closure on AEs following colorectal ESD.
