Cumulative incidence and risk factors for pouch adenomas associated with familial adenomatous polyposis following restorative proctocolectomy

Figure 1 Patient selection flow chart. FAP: Familial adenomatous polyposis; TPC: Total proctocolectomy; IPAA: Ileal pouch-anal anastomosis; IRA: Ileorectal anastomosis.

Figure 2 Cumulative incidence of pouch adenomas. IPAA: Ileal pouch-anal anastomosis.

Figure 3 Progression of pouch adenomas. Patients in the countable group had all adenomas removed, and numerous groups were only undergoing surveillance biopsy.
