Figure 1 Endoscopic full-thickness resection treatment of gastric stromal tumors arising from the muscularis propria. A: A protruding submucosal lesion in the gastric body; B: Endoscopic ultrasound showing that the lesion arose from the muscularis propria; C: Submucosal injection of saline containing adrenaline and indigo carmine; D: Application of the IT knife to isolate the stromal tumor along its periphery; E: An “artificial perforation” observed after stromal tumor resection, sealed using titanium clips; F: Sealing of the perforation with multiple titanium clips; G: Resected tumor with the mucosa removed (5 cm in diameter); H: View 72 d after the operation, showing that the perforation healed well, with only ulcer residue remaining.
