Abstract

BACKGROUND/AIMS
Endoscopic mucosal resection (EMR) has been widely used for treatment of gastric mucosal tumors because of its relative safety and minimal invasiveness. However, the bleeding after EMR has been regarded as a major complication. Herein, we assessed the bleeding rates and risk factors related to bleeding after EMR.
METHODS
We retrospectively analyzed the medical records of two hundred and fortynine patients with 283 lesions who underwent EMR for flat adenoma (78.8%), hyperplastic polyp (4.9%), and early gastric cancer (16.3%) from January 1999 to August 2003. Bleeding during EMR was defined as an immediate bleeding while bleeding on follow-up day endoscopy after EMR was considered as an delayed bleeding We evaluated risk factors related to bleeding using univariate and multivariate analysis.
RESULTS
Bleeding after EMR occurred in 99 patients (35%). Immediate bleeding occurred in 31.8% and was more frequent in the case of beginners, upper part of the stomach or EMR prcedures using needle knife. Delayed bleeding occurred in 7.1% and was more frequent in the case of flat or depressed lesions, or occurrence after the incidence of immediate bleeding. Risk factors related to EMR bleeding were experience of operator (beginner vs. expert, p= 0.001), anatomical location (upper vs. lower, p=0.018), and methods of procedure (needle-knife vs. snare or band, p=0.001).
CONCLUSIONS
We concluded that experience of operator, anatomical location, and method of procedure were the risk factors related to bleeding after EMR.
