Eligible lesions measured \u22641.0\u2005cm and were identified using endoscopic ultrasonography as originating from the muscularis mucosae, submucosa, or muscularis propria.

No significant differences were observed in the en bloc resection rate, R0 resection status, incidence of procedure-related complications, duration of hemostatic drug use, and length of hospital stay between the ligation-assisted endoscopic mucosal resection and endoscopic submucosal dissection groups.
