Successful Endoscopic Submucosal Dissection for Giant Inflammatory Fibroid Polyp in Terminal Ileum.

ABSTRACT: A 55-year-old woman presented with postprandial abdominal pain and diarrhea. Contrast-enhanced abdominal computed tomography revealed a large tumor in the ileocecal region. Colonoscopy demonstrated a pedunculated polyp originating from the terminal ileum, intermittently prolapsing into the cecum with a stalk-like base. Biopsy specimens showed nonspecific inflammatory changes. Initial hot snare polypectomy was unsuccessful due to the polyp's large size and mobility. Therefore, endoscopic submucosal dissection using the underwater pocket-creation method was performed, with the polyp stabilized using a traction device anchored to its apex and the opposite side of the ileocecal valve. This technique enabled safe resection of the lesion from its broad stalk. Although marked submucosal fibrosis
