Acute ischaemic colitis following intravenous cocaine use.

: Intestinal ischaemia is an uncommon complication of recreational cocaine abuse. We report the case of a 36-year-old male who underwent emergency surgery for acute abdomen. At laparotomy, the transverse colon appeared markedly oedematous, dilated and with subserosal haemorrhage. Segmental resection was performed and microscopic examination of the resected specimen showed focal necrosis of the mucosa with a patchy polymorphonuclear and mononuclear infiltrate. The submucosa was markedly thickened due to oedema; focal haemorrhage was observed and blood vessels were dilated but showed no structural abnormalities or thrombosis. These findings were consistent with ischaemic colitis. No risk factors for intestinal ischaemia were present but the patient stated that he had injected cocaine i.v. the day before the onset of symptoms. He was not a cocaine abuser but occasionally sniffed, smoked or injected cocaine. Cocaine use should be considered in the aetiological diagnosis of intestinal ischaemia in young patients.
