Colonic haemorrhage: A technique for rapid intra-operative bowel preparation and colonoscopy

We describe a new technique of operative orthograde colonic washout followed by colonoscopy for use in patients with severe colonic haemorrhage. We report its use in four patients in whom the exact source of bleeding was localized and treated. In two of these cases a policy of ‘blind’ hemicolectomy would have been incorrect. The technique is simple and safe, and we advocate its use during laparotomy for major colonic haemorrhage.
