2) IPAA for UC nd PSC-UC have same long term results

3) IPAA for PSC-UC have high chronic pouchitis

4) IPAA for PSC-UC associated with low risk of anastomotic varices

Ans is 2

26% of patients with PSC develop Peristomal varices with end ilesotomy as compared to none with IPAA ( SKF page 1382) 

Cumulative risk of pouchitis at 10 years after IPAA was 61% for patients with PSC and CUC, as compared with
36% for patients with CUC alone ( so B is false SKF page 1382)
