Abstract

BACKGROUND:

Endoscopic mucosal resection has been increasingly used to treat gastric tumors. Bleeding is the major complication of endoscopic mucosal resection. This study evaluated risk factors for bleeding associated with endoscopic mucosal resection.

METHODS:

Four hundred seventy-seven patients who underwent endoscopic mucosal resection of gastric tumors during the past 10 years were studied retrospectively. Bleeding encountered during endoscopic mucosal resection was termed immediate; bleeding after endoscopic mucosal resection was termed delayed. Univariate and multivariate analyses were used for determination of the factors related to delayed bleeding. One case of perforation was excluded.

RESULTS:

Delayed bleeding occurred in 25 (5.3%) of 476 patients. The only factor found to be significantly different between cases with and without delayed bleeding was the occurrence of immediate bleeding during endoscopic mucosal resection (p < 0.001). Sites where immediate bleeding occurred were not the same as those where delayed bleeding arose. There were no significant differences in other factors.

CONCLUSIONS:

When immediate bleeding occurs during endoscopic mucosal resection, there is an increased risk of delayed bleeding.
