[Postoperative ischemic ileocolitis in the elderly. Suggested therapy with intraluminal administration of oxygen and glutamine].
Ischaemic ileocolitis in postoperative course of major abdominal surgery is a great challenge for the surgeon: the mortality rate is very high, and therapeutic choices are poor. In the elderly patients ischaemic bleeding ileocolitis is often determined by low flow: sepsis and cytologic damage are primed by activation of endotoxins and chemical mediators, and bacterial translocation could develop across intestinal wall. In our case the patient (male, caucasian, 68 years old) underwent bilio-hepatic resection for hilar cholangiocarcinoma. In the postoperative period continuous enteric haemorrhage was determined by an ischaemic ileocolitis demonstrated by colonoscopy. Abdominal angiography did not show stenosis or occlusion of mesenteric vessels. We administered dopamine and dobutamine as vasodilator drugs for splanchnic circulation without any positive response. Surgical removal of the colon was unsuccessful to stop bleeding. ileostomy and sigmostomy were performed. Histologic samples of the specimen showed ischaemic ileocolitis. After a few days the patient bled again. As last therapeutic choice, we bubbled oxygen in a solution of L-glutamin 500 mml (3 liters/min for 5 min). We administered 500 mml of this solution three times a day by enteral sond, and 100 mml twice a day by sigmoidostomy and endoluminal oxygenation was performed twice a day (1l/min for 1-2 minutes) under continuous control. Bleeding was reducing during the next five days, until stopping. If glutamine and O2 can be considered the fuel of enterocytes, we hypothesized endoluminal oxygenation and glutamine enteral supply of the small intestine could feeding enterocytes, until a complete restoration of enteral mucosa and stopping of the haemorrhage.
