A transvalvular polypectomy of a giant ileal inflammatory fibroid polyp by retrograde single-balloon enteroscopy.

The ileocecal valve was cannulated and the polyp's origin in the ileum was confirmed. A subsequent computed tomography (CT)-based virtual colonoscopy showed a 6-cm finger-like-shaped polyp with its base in the terminal ileum approximately 5 cm proximal to ileocecal valve (Fig. 1 Computed tomography-based virtual colonoscopy showing the finger-like-shaped ileal polyp (yellow circle).
