Abstract

Introduction: Ulcerative colitis (UC) is a chronic colonic mucosal disease with unknown etiology. Its frequency is rising in our country in recent years. With application of newer topical preparation in treatment of UC a true recognition of its colonic extension pattern is needed. Reports from Iran are scarce. Reports from the world are contradictory. This study, therefore, was done to determine frequency of colonic extension in patients with UC in western part of Iran.
