Prognosis of surgically treated radiation-induced damage to the intestine.

• A series of 88 patients operated on during 24 years for radiation-induced damage (RID) to the intestinal tract were retrospectively reviewed and clinical and surgical factors were related to the ultimate prognosis by multivariate analysis. The first operation was performed on the small intestine in 47 patients, the large intestine in 32 patients or both in nine patients. Postoperative complications occurred in 35 patients (40%), with fatal outcome in 12 (13%). Thirty-one patients (35%) required further surgery and altogether 19 patients (22%) ultimately died from RID. Negative prognostic factors after the first operation were postoperative intestinal leak (P < 0.05) and operation for fistula or perforation (P < 0.01). The outcome after the last operation was negatively influenced by intestinal leak (P < 0.001) by the choice of bypass as operative procedure (P < 0.01) and by operation for fistula or perforation (P < 0.01). In addition, 43% of the patients in whom the disease had progressed between two explorations died from RID. Thus, the severity of the RID as diagnosed at laparotomy, and progression of the disease between two subsequent explorations were related to the prognosis. Care should be taken to avoid intestinal leak. Resections should be preferred to bypass of injured intestine whenever possible.
