 Because of improved surveillance colonoscopy techniques, the number of patients with cancer or dysplasia complicated with ulcerative colitis who undergo surgical treatment is increasing, as patients are more routinely diagnosed at a relatively early stage. Thus, well-differentiated adenocarcinoma is the most common histologic type. The prognosis of affected patients is relatively good, with a cumulative 5-year survival rate of approximately 90%. Surgical problems are often encountered in colitic cancer patients who are overweight or obese, with an increased number of patients in which the J-pouch does not reach the anus. Additionally, as a potential future complication, care is necessary regarding cancer in the pouch in refractory cases of pouchitis. In such patients, partial resection of the large intestine and endoscopic treatment should be carefully selected.
