Item does not contain fulltext- The surgical treatment of choice for ulcerative colitis is colectomy followed by ileostomy or the construction of an ileo-anal pouch, which results in an improvement in quality of life.- The pouch can be constructed in one operation after a total colectomy or in two steps: first, constructing an ileostomy after a subtotal colectomy and second, constructing the pouch after a proctectomy. - The most common pouch-related diseases include surgical complications such as abscesses, fistulas and leaks, and inflammatory complications like pouchitis, cuffitis and Crohn's disease of the pouch.- The most important diagnostic tool to differentiate between the often difficult to distinguish pouch-related diseases is a pouchoscopy. - There are no evidence-based treatment strategies for pouch-related diseases due to the lack of large randomized placebo-controlled trials. - Pouch-related diseases can lead to pouch failure which may require surgical reintervention with revision or excision of the pouch
