Segmental Sigmoid Polyposis as a Colonoscopic Indicator of an Ileosigmoid Fistula in Crohn's Ileitis

摘要

Background and aims: Ileosigmoid fistulas (ISFs) are frequently undiagnosed prior to surgery. This study was designed to describe a polyp or cluster of polyps limited to the sigmoid colon as a marker of ISF in patients with ileitis. This novel finding will increase a gastroenterologist's opportunity to detect them preoperatively and their prognostic implication of worsening ileitis.
