Background: Endoscopic resection (ER) of gastric submucosal tumors (G-SMTs) is challenging due to the difficulty of exposure. Traction-assisted ER has been shown to provide better outcomes than traditional endoscopic operation by exposing the dissection plane. In this study, we investigated the efficacy and safety of the snare traction-assisted method in ER of G-SMTs.
Method: From May 2021 to March 2023, we used snare traction-assisted method to treat 24 patients with 24 G-SMTs in our department. Clinical characteristics and the outcomes of ER were recorded.
Result: The mean tumor diameter was 1.8±0.9 cm. Six G-SMTs underwent endoscopic submucosal dissection (ESD), and 18 underwent endoscopic full-thickness resection (EFTR). En bloc resection and R0 resection was achieved in all the 24 lesions. The average procedure time was 45.4 ± 23.4 minutes. The patients were discharged in 5.0 days after procedures, without delayed bleeding or other adverse events.
Conclusion: Snare traction-assisted method provides an effective traction for endoscopic resection of G-SMTs even if the tumor is difficult to remove. While further studies comparing the snare traction-assisted method with the conventional procedure are necessary.
