PurposeEffectiveness of bedside Colonoscopies in Intensive Care Unit (CICU) might be limited by the poor quality of colonic preparation, and their feasibility. We sought to describe the indications and the profitability of CICU.MethodsRetrospective, bicenter observational study (2004-2015) in unselected critically ill patients. We questioned the clinical profitability of CICU, according to its indications and preparation.ResultsOne hundred and eleven CICU were performed in 84 patients (sex ratio 1.4, 49 M/35F; age 72.9 years [61.7-84.7]), for lower gastro-intestinal bleeding in 67 patients (LGIB, 60.3%) and for other causes in 44 (39.6%). The profitability was more frequent when CICU was performed for another reason than LGIB (75% vs 28.3%; p < 0.0001). Preparation was good in 47 procedures (42.3%) and allowed 33 complete CICU (29.7%). Fifty-six CICU (50.4%) were performed as a 2nd investigation after a contrast enhanced computed tomography. Three CICU were complicated by 3 hemodynamic and 2 respiratory failures, but none of them were fatal.ConclusionsCICU is clinically useful in half of cases, in the diagnostic and the therapeutic management of critically ill patients. Its profitability is close to scheduled colonoscopies and superior in non-lower gastro-intestinal bleeding indications.Copyright © 2021. Published by Elsevier Inc.
