Ulcerative Collitis: Need Information

Fellow bloggers and readers, though I avoid posting very personal posts here this one is an exception. My mother has been suffering from Stomach ulcer (Ulerative Collitis) since almost 1.5 years. Recently she was advised to undergo surgery (ileopouch anastomosis). If you know any body who has undergone such a surgery kindly let me know the pros and cons of this surgery. One who has undergone this operation would be in the best position to explain the post operation problems if any. Would be grateful for your help. Please pass on this information.
