Endoscopic Ultrasound (EUS) Before Gastric Polyp Resection

Abstract

Gastric polypectomy is associated with increased risk of bleeding. The use of endoscopic ultrasound (EUS) before polypectomy to decrease the rate of bleeding in such patients has not been studied. All gastric polyps excised by snare polypectomy were evaluated. The primary outcome was the occurrence of immediate or delayed bleeding episodes. Postpolypectomy bleeding was correlated with the presence of blood vessels at the base of the polyp on EUS examination. Characteristics of both patients and polyps were analyzed as risk factors for postpolypectomy bleeding. One-hundred and two snare polypectomies were performed. Fifty-seven polyps (56%) had been evaluated by prior EUS. Bleeding occurred in 7 (7%) patients. Of these, 4 had not undergone EUS evaluation, whereas in 3 patients who had had a prepolypectomy EUS evaluation, none were found to harbor a visible blood vessel. Bleeding did not occur in any of the 8 patients in whom EUS suggested the presence of blood vessel. The size, location, type, and histology did not show any significance in predicting postpolypectomy bleeding. The risk of bleeding after endoscopic resection of gastric polyps was 7%. EUS evaluation before gastric polypectomy does not seem to contribute to the safety of such a procedure.
