Endoscopy for Altered Anatomy in Inflammatory Bowel Disease.

A significant proportion of patients with Crohn's disease or ulcerative colitis will ultimately necessitate surgical interventions, despite advances in diagnosis, medical therapy, and endoscopic interventions. These surgeries lead to substantial alterations in bowel anatomy. The present review aims to emphasize the key role of conducting a comprehensive endoscopic evaluation of both anatomic landmarks and endoscopic features for accurate clinical interpretation, thereby impacting decisions regarding medical or endoscopic interventions.
