Polyglycolic acid sheets and fibrin glue decrease the risk of bleeding after endoscopic submucosal dissection of gastric neoplasms (with video).

Background: The prevention of bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasms is still an important problem.

Objective: To investigate the efficacy and safety of a shielding method that uses polyglycolic acid (PGA) sheets and fibrin glue to prevent post-ESD bleeding in high-risk patients.

Design: A nonrandomized trial with historical control subjects.

Setting: A single academic hospital in Japan.

Patients: From July 2013 to February 2014, 45 ESD-induced ulcers in 41 patients with a high risk of bleeding were enrolled in a study group. Forty-one consecutive ESD-induced ulcers in 37 control subjects with a high risk of bleeding were treated in 2013 before the first enrollment.

Interventions: We placed PGA sheets on the mucosal defect and fixed with fibrin glue in the study group.

Main Outcome Measurements: The post-ESD bleeding rate.

Results: The post-ESD bleeding occurred at a rate of 6.7% in the study group (3/45 lesions) and 22.0% in the historical control group (9/41 lesions). There was a significant difference in the post-ESD bleeding rate between the 2 groups (P = .041).

Limitations: A nonrandomized trial with historical control subjects; a single-center analysis; small sample size.

Conclusions: The endoscopic tissue shielding method with PGA sheets and fibrin glue appears to be promising for the prevention of post-ESD bleeding. (
