163 ENDOSCOPIC FULL THICKNESS RESECTION COMPARED TO SUBMUCOSAL TUNNEL ENDOSCOPIC RESECTION FOR TREATMENT OF GASTRIC GIST

Submucosal tunnel endoscopic resections (STER) had been increasingly performed for treatment of gastric GIST. One of the limitations for STER is the risk of incomplete tumor resection due to close dissection and bridging of tumor capsule. Endoscopic full thickness resection (EFTR) allowed complete resection of the tumor with margins to prevent recurrence. This study aimed to compare EFTR against STER for treatment of gastric GIST.
