Aim: The aim of this study was to compare the efficacy and safety of snare-assisted endoscopic resection with endoscopic submucosal dissection for the treatment of gastric submucosal tumors (< 1 cm) originating from the muscularis propria.
Methods: From January 2020 to December 2022, gastric submucosal tumors (< 1cm) treated endoscopically in our hospital were collected and analyzed. According to different endoscopy technique, patients were divided into snare-assisted resection group and endoscopic submucosal dissection group. The clinical baseline data, endoscopy therapy results and follow-up of the two groups were collected and compared.
Results: A total of 85 patients were included in this study, of which 35 patients underwent snare-assisted endoscopic resection and 50 patients underwent endoscopic submucosal dissection. There were no differences in clinical baseline data, en bloc resection rate, postoperative fasting time, and postoperative hospital stay between the two groups. The operation time of the snare-assisted endoscopic resection group was significantly shorter than that of the endoscopic submucosal dissection group. One patient in the endoscopic submucosal dissection group developed intraoperative perforation and was treated with endoscopic closure. No adverse events occurred in the snare-assisted endoscopic resection group. During the mean follow-up period, no recurrence was observed in both groups.
Conclusion: Snare-assisted endoscopic resection is a safe and effective technique, which is an alternative choice for the treatment of gastric submucosal tumors. However, its long-term efficacy still needs to be assessed by large-sample studies.
