End-Stage Renal Disease Still Risk Factor for Colonoscopy Complications

End-stage renal disease (ESRD) has been considered a risk factor for colonoscopy complications because of platelet dysfunction, in the case of bleeding, and perhaps tissue fragility, with regard to perforation.
In a study from Taiwan of postpolypectomy bleeding and polypectomy-related perforation from 1997 to 2013 involving 5302 ESRD patients and the same number of matched controls, the overall incidence of postpolypectomy bleeding or perforation was higher in the ESRD group (5.83% vs 1.78%). Also in the ESRD group, nonfatal complications requiring hospitalization were higher at 5.24% versus 1.51%, and fatal bleeding or perforation was 0.4% versus 0.2%. The odds ratio for bleeding or perforation after polypectomy in multivariable analysis was 2.38 for end-stage renal disease.
