Similar Adenoma Detection Rates in Colonoscopic Procedures of Patients with Spinal Cord Injury Compared to Controls.

Background: Cancer is a major cause of death in patients with spinal cord injury (SCI). Preventive strategies, such as colonoscopy, deal with higher burdens that may lead to lower quality.
Aims: The primary objective was to evaluate the adenoma detection rate. Secondary objectives were to investigate other quality indicators regarding bowel preparation, sedation, and endoscopy.
Methods: Consecutive SCI patients who had undergone colonoscopy from 2003 to 2014 were assigned to a control group matched for age, gender, and year of procedure and reviewed retrospectively.
Results: Bowel preparation lasted longer (3.6 ± 1.5 vs. 1.2 ± 0.6 days, p = 0.001), achieved unsatisfactory cleansing results more often (23.7 vs. 3.6%) and caused more adverse events in 236 SCI compared to 414 control patients. Colonoscopy needed a longer time (36.9 vs. 25.0 min) and remained incomplete more often (24.6 vs. 4.6%), resulting in more re-colonoscopies (14.8 vs. 4.3%). Endoscopy- and sedation-related adverse events were equal. However, neither overall nor size-dependent polyp (30.9 vs. 34.8%), adenoma (21.2 vs. 21.0%), advanced adenoma (6.8 vs. 7.2%), or cancer (1.7 vs. 2.0%) detection rates differed.
Conclusion: Despite intensified protocols, bowel preparation shows inferior results in SCI patients; colonoscopy needs more effort to succeed but achieves a comparable quality.
