Risk of Post-polypectomy Bleeding After Colorectal Endoscopic Mucosal Resection in Patients with Chronic Kidney Disease: A Propensity-Matched Analysis of the US Collaborative Network.

ABSTRACT:

Background

Studies evaluating the risk of post-polypectomy bleeding (PPB) after colorectal endoscopic mucosal resection (EMR) in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) are limited.

Methods

This retrospective cohort study utilized the U.S. Collaborative Network to assess the risk of PPB after colorectal EMR in patients with CKD compared to controls. Using one-to-one propensity score matching (PSM), the primary outcome measured was PPB within 30 days after colorectal EMR. The PPB risk was further stratified by CKD severity: non-advanced CKD and advanced CKD.

Results

After PSM, each cohort included 9,196 patients. Overall, CKD was associated with increased risk of PPB following colorectal EMR (5.4% vs. 3.8%, odds ratio [OR] 1.44, 95
