Post-polypectomy bleeding (PPB) is the most common complication of colonoscopy. The purpose of this study was to explore the effect of inadequate bowel preparation on urgent colonoscopy in patients with PPB.In this retrospective, single-centre study, we enrolled PPB patients who underwent urgent colonoscopy at a university-affiliated hospital from 2010 to 2020 and assessed the outcome indicators of interest (diagnostic rate, ileocaecal intubation, repeated colonoscopy, endoscopic therapy, success rate of treatment) and clinical outcomes (surgery, transfusion requirement, length of stay (d), cost ($)).Of the 34 included patients with PPB, 29 were males and 5 were females. The mean age of the patients was 56.7±9.7 years, and 19 patients (55.9%) had chronic diseases; 6 patients in the sample were treated with enema for bowel preparation, and 28 patients were prepared with endoscopic irrigation. In all patients, the source of bleeding was found by endoscopy, endoscopic treatment was provided, and the bleeding was successfully stopped.Our study showed that, for patients with PPB, inadequate bowel preparation might not compromise the effectiveness of urgent colonoscopy, and the hospitalization cost was low.
