[Abdominal pain, fresh blood in the anus].

A 60-year-old lady with type II diabetes, arterial hypertension and 'melancholia' was treated with Lithium, a neuroleptic (Leponex) and an ACE inhibitor (Reniten). She was referred to our hospital because of abdominal pain, subfebrile temperatures, diarrhea and hematochezia. The radiological and sonographic examinations showed a thickened wall of the left hemicolon. Colonoscopy revealed a sharply delineated segment with pronounced inflammation in the descending colon and the proximal sigmoid colon, suggestive for an ischemic colitis. Histology of the inflamed colon was compatible with this diagnosis. Under suspended enteral feeding and antibiotic therapy the symptoms disappeared within two weeks, and a control colonoscopy six weeks later was completely normal. 1 1/2 years later the patient suffered from a second episode of ischemic colitis exactly a the same site. Again, complete cure was achieved by conservative treatment.
