Radiation enteropathy.

Abstract

PURPOSE:

Radiation enteropathy presents a complex clinical picture which varies from case to case. Diagnosis and treatment require a thorough knowledge of the natural history of the condition and of the complications which are to be expected.

PATIENTS AND METHODS:

The pathogenesis, clinical picture, diagnosis and treatment of radiation damage to the gut are described. The progress of 90 patients operated on in the Chirurgische Universitätsklinik Freiburg is retrospectively evaluated.

RESULTS:

Haemorrhage, vomiting, diarrhoea and, occasionally, perforation are the signs of acute radiation enteropathy, which appears weeks or months after radiotherapy. Except for perforations, these can usually be treated conservatively. Chronic radiation enteropathy does not manifest itself until years after irradiation, with diarrhoea, obstruction and the development of fistulae. The acute ileus can often be relieved with decompression tubes. After localising the stenosis radiologically with a contrast medium, and improvement in the general condition, many cases require operative intervention. This usually consists of resection, the establishment of a bypass anastomosis or enterostomy. In 44% of the patients postoperative complications followed, with a mortality of 22%. The cause of the high complication rate is partly the poor general condition of the patient, and partly the radiation induced impairment in wound healing, which may lead to insufficiency of the anastomosis and the development of fistulae.

CONCLUSIONS:

The treatment of radiation enteropathy is a demanding task. Because of the high complication rate, it is generally wise to choose the least risky procedure.
