Effect of Procedural Volume on Adverse Outcomes in Gastric Endoscopic Submucosal Dissection

A nationwide population-based study investigated the influence of procedural volume on the outcome of gastric endoscopic submucosal dissection (ESD) for gastric cancer or adenoma. The study included 88,687 patients who underwent 94,246 procedures between November 2011 and December 2017. The results showed that high- and medium-volume centers had a significantly lower risk of adverse outcomes compared to low-volume centers, including a lower risk of hemorrhage, perforation, and pneumonia. Procedural volume was closely associated with clinical outcomes in patients undergoing ESD for gastric cancer or adenoma.
