Autoimmune hemolytic anemia associated with ulcerative colitis arising after colectomy

: Autoimmune hemolytic anemia is a rare, although not exceptional, complication of ulcerative colitis. This report presents a case of this association, which is noteworthy in that the hematologic picture appeared immediately after colectomy was performed due to colonic perforation. The features of the only three reported cases in which anemia developed after colectomy are reviewed, and the role of this surgical technique in the treatment of hemolytic anemia associated with ulcerative colitis is discussed. Although colectomy does not protect patients with ulcerative colitis from the onset of hemolytic anemia, we consider that proctocolectomy should be included among the therapeutic alternatives when this association is present, especially in the case of refractory colitis.
