Endoscopic resection, including endoscopic submucosal excavation (ESE) and endoscopic full-thickness resection (EFTR), is an effective and safe method for gastrointestinal stromal tumors (GISTs). While during traditional EFTR, closure of the defect using a loop-andclip closure technique or just clips always follows the full-thickness resection, this usually results in the occurrence of gasrelated complications, such as pneumoperitoneum [1, 2]. What is more, it is time-consuming and not easy to perform for some lesions larger than 2.0 cm. In this study, we performed a modified EFTR, whereby a full-thickness resection and closure of the defect were performed simultaneously until the lesion was completely removed (â–¶Video 1).
