The Role of Hemoclips Reinforcement in the Ligation-Assisted Endoscopic Enucleation for Small GISTs in Gastric Fundus

Abstract EN

Background.

Endoscopic ultrasonography- (EUS-) assisted band ligation has been proven to be a safe and effective procedure for the treatment of small gastrointestinal stromal tumors (GISTs) apart from the relatively high risk of the postligation perforation of the gastric fundus.

The aim of this study is to investigate the efficacy of hemoclip reinforcement in treating small GISTs in the gastric fundus.

Method.

During a standard endoscopy, a transparent cap attached to the endoscopic tip was placed over the lesion to exert sustained maximal aspiration before a rubber band was released.

Once a definite ligation was confirmed by EUS, the tumor was enucleated.

Four to 6 hemoclips were placed on the folds around the ligation band to reduce the tension of the ligation site.

Results.

The small GISTs were resected completely in 192 patients.

Two cases of delayed perforation were found 72 hours after the procedure and successfully treated with an ordinary conservative method.

Conclusion.

Hemoclip-reinforced endoscopic band ligation with systematic follow-up using EUS appears to be a simple and effective technique for the resection of small GISTs in the gastric fundus.
