Abstract

PURPOSE
Post-polypectomy bleeding is the most common colonoscopic polypectomy complication. However, the risk of post-polypectomy bleeding in liver cirrhosis is unknown. We aimed to evaluate the risk of post-polypectomy bleeding in patients with liver cirrhosis.
MATERIALS AND METHODS
We included 89 patients with liver cirrhosis who received colonoscopic polypectomy between January 2006 and October 2012. Three hundred forty-eight subjects without liver disease who underwent colonoscopic polypectomy comprised the control group. Risks of post-polypectomy bleeding were analyzed according to patient- and polyp-related factors.
RESULTS
Among 89 patients, 75 (84.3%) were Child-Pugh class A, 10 (11.2%) were class B, and 4 (4.5%) were class C. Incidence of immediate post-polypectomy bleeding was significantly increased in cirrhosis with Child-Pugh class B or C compared to liver cirrhosis with Child-Pugh class A or control group [hazard ratio (HR) 3.5; p<0.001]. Polyp size (HR 3.6; p=0.032) and pedunculated polyps (HR 2.4; p=0.022) were also significant risk factors for immediate post-polypectomy bleeding in multivariate analysis.
CONCLUSION
Cirrhotic patients with Child-Pugh class B or C have a high risk of immediate post-polypectomy bleeding. Thus, endoscopists should be cautious about performing colonoscopic polypectomy in patients with Child-Pugh class B or C.
