Retrospective comparison of precutting endoscopic band ligation and endoscopic submucosal dissection for small gastric muscularis propria tumors

Figure 2 Diagrams of precutting endoscopic band ligation for submucosal tumors originating from the muscularis propria layer. A: Small gastric submucosal tumors originating from the muscularis propria layer; B: A power of 30 watts was used for surgical resection, with precutting and peeling of the mucous membrane; C: The mucosa was denuded from the submucosal lesion, and a transparent ligator cap was attached to the endoscope; D: The exposed tumor was fully aspirated into the cap; E: The band was loosened, and the entire tumor was ligated; F: The tumor was left to fall off due to necrosis, a process that takes about 2-7 days.
