Core Tip	Submucosal tunnel docking endoscopic resection (SDER) is a modified technique for treating a large submucosal tumor (SMT) at the gastroesophageal junction. We report a case of an 8-cm gastric leiomyoma involving three-quarters of the cardia. SDER was performed by first creating an esophageal submucosal tunnel to dissect the tumor base, followed by retroflexed endoscopic dissection in the stomach. The tumor was completely resected without bleeding or perforation. This technique may provide a safe and effective option for large, irregularly shaped SMTs at this challenging location.
