Case reports or case series have been excluded. This table provides the overall number of IBDs treated in a selected time span. Whenever available, the series were differentiated into patients with UC, CD and IC. Overall, a relatively high prevalence of major complications requiring some sort of surgical intervention has been reported (higher than 29%), still similar or even lower when compared to what previously published for open surgery. Complications rate was calculated basing on series providing incidence (541 overall patients). IBD: Inflammatory bowel disease; CD: Crohn’s disease; UC: Ulcerative colitis; IBD-U: Inflammatory bowel disease - unclassified; NS: Not stated.
