Colon necrosis halmozott elofordulása szívmutét után.

In the last 2 years 9 patients have been operated on in our surgical department because of colon necrosis which developed after open heart surgery. The symptoms--abdominal distension, circumscript peritonitis in the right lower part of the abdomen--developed 2-4 days after the heart operation. Laparotomies were carried out within 2 days from the onset of symptoms in all but one patient. In 7 patients the necrosis of the right colon, while in 2 other patients extreme dilatation of the colon was found. In 6 patients right hemicolectomy was carried out. One operation was finished without anastomosis with double stomas. In the 2 patients with no necrosis catheter-cecostomy was performed. All patients but one after hemicolectomy with reconstruction died after several reoperations because of suture leak. The other 3 patients were cured. We examined and analysed the pre-, intra- and postoperative circumstances of the heart operations, which lead to the severe complications. We think the cause of the problems was the liberal use of wide spectrum antibiotics with caused severe dysbacteriosis and Clostridium difficile toxicosis in the colon. This condition could lead to a pseudomembraneous colitis which resulted in the colon necrosis.
