Combined application of the preclosure technique and traction approach facilitates endoscopic full-thickness resection of gastric submucosal tumors

Figure 1 Endoscopic full-thickness resection procedure for a submucosal tumor, and the wound was preclosed with titanium clips before the lesion was completely removed. A: Giant gastric submucosal tumor found after stripping the mucosa and submucosa; B: Full-thickness resection around the tumor via the dental floss traction method; C: Preclosure of the gastric wound with clips once most of the tumor had been excised; D: Dissection of the remaining tumor tissue; E: Complete closure of the gastric wound with titanium clips; F: The full-thickness gastric wall surrounding the tumor is visible to the naked eye in this specimen.

A: The size and number of the tumors in the preclosure group of patients; B: The size and number of the tumors in the non-preclosure group of patients. 1 representation 0-0.5 cm. 2 representation 0.5-1 cm. 3 representation 1-1.5 cm. 4 representation 1.5-2 cm.
