| Summary: | Background and study aims Mucosal traction as a supportive technique is very useful for endoscopists during endoscopy. For gastric submucosal tumor (SMT), our team explored a method of pulling the SMT with a snare combined with endoclips (PSMT-SE). This study preliminarily explored its feasibility to assist resection of gastric SMT.
Patients and methods Operation-related data from patients who underwent gastric SMT removal assisted by PSMT-SE at the Gastrointestinal Endoscopy Center of Guangzhou Nanfang Hospital, China between January 2017 and October 2018 were retrospectively collected: tumor size and location, origin of tumor, total operation time, en bloc resection rate, intraoperative and postoperative complications.
Results Forty-two gastric SMTs in 41 patients were included in this study. Fifteen tumors were located in the gastric fundus, 11 in the gastric body, two in the gastric angle, 10 in the gastric antrum, and four in the greater curvature of the gastric fundus and the body junction. Further, 11 tumors originated from the submucosa and 31 originated from the muscularis propria. Endoscopic submucosal dissection and endoscopic full-thickness resection assisted by PSMT-SE were performed to resect 30 and 12 tumors, respectively. PSMT-SE could effectively expose the surgical field. Median diameter of resected tumors was 2.0 (0.7) cm, the total operation time was 45.5 (27.0) min, and the en bloc resection rate was 100 %. No intraoperative or postoperative complications were observed.
Conclusion PSMT-SE is a potentially useful method for assisting resection of gastric SMT with tumor traction. Further prospective studies with large sample sizes are warranted. |
