Mortality and rate of hospitalization stratified by patients' BMI in a colonoscopy screening - a cross sectional analysis of data from Polish Colonoscopy Screening Platform.

Background: Currently, it remains unknown whether there is an association between body mass index (BMI) and complications during screening colonoscopy; hence, it remains unclear whether BMI should be considered a risk factor in pre-procedural assessments. The aim of this study was to compare mortality and unplanned hospitalization rates before and after colonoscopy stratified by patients' BMI.

Material And Methods: This was a retrospective cohort study of individuals who underwent screening colonoscopy as part of the Polish Colonoscopy Screening Program (PCSP).
