Application value of electric snare assisted by single ligator in the treatment of upper gastrointestinal submucosal lesions

ObjectiveTo investigate the effects of endoscopic submucosal lesion resection with electric snare assisted by single ligator in the treatment of upper gastrointestinal submucosal lesions.

MethodsForty patients with submucosal lesions of the muscularis propria in upper gastrointestinal tract diagnosed by endoscopic ultrasonography were randomly divided into the observation group(20 cases) and control group(20 cases).The observation group was treated with endoscopic submucosal lesion resection with electric snare assisted by single ligator, and the control group was treated with conventional endoscopic mucosal dissection.The operative time, intraoperative blood loss, intraoperative perforation and site of perforation were observed in two groups.The first endoscopic following up was conducted after 3 months of operation, and the follow-up time and recurrence were recorded.

ResultsThe lesions in 40 patients were one-time resected.The operative time and intraoperative blood loss in observation group were significantly less than those in control group(P < 0.01).No intraoperative perforation case was found in the observation group, and one patient with intraoperative perforation was found in the control group.All patients were followed up for 3-36 months, and no residual or recurrence was found.

ConclusionsEndoscopic submucosal lesion resection with electric snare assisted by single ligator in the treatment of upper gastrointestinal submucosal lesions is simple, safe, with few complications, and high efficient.It is worthy of clinical application.
