Reporting ileocolonoscopy in inflammatory bowel disease.

摘要

The UC disease margin is important when selecting oral versus rectal therapy and when assessing dysplasia risk. The margin can be described most usefully as the most proximal anatomical segment of the colon where inflammatory changes are identified. This differentiates pancolitis from extensive colitis (margin proximal to the splenic flexure but distal to cecum), distal or left-sided colitis (margin distal to the splenic flexure), proctosigmoiditis and proctitis. Where the disease margin is distal to the splenic flexure, the report should also measure the disease margin's distance from the anal verge. Measurements are most meaningful and reproducible if they are taken during scope withdrawal; stretching of the colon while the scope is advanced can overestimate distance significantly.
