Gastrocolic fistula, a rare complication.

A 77-year-old male presented with diarrhoea, weight loss and faeculent vomiting. CT scan identified a stricturing lesion in the transverse colon. The man, however, had no features suggestive of large bowel obstruction. This unusual presentation of faeculent vomiting raised a suspicion of a possible communication between the colon and stomach. A subsequent CT scan with oral contrast confirmed the presence of a gastrocolic fistula. During explorative laparotomy, a transverse colonic tumour communicating into the stomach via the gastrocolic fistula was detected. The patient underwent an extended right hemicolectomy and distal gastrectomy as a palliative measure. A gastrocolic fistula is a rare, yet important find and should be recognized as a possible sequel of this disease process.
