Case description

Lesions are observed during water lavage. Radiation-induced injury is best described in 2 ways. Acute injury is a function of fractionation of the dose, field size, type of radiation, and frequency of treatment. Acute injury is caused by injury to the mitotically active intestinal crypt cells. On the other hand, chronic radiation injury is caused by injury to the less mitotically active vascular endothelial and connective tissue cells. Chronic injury is a function of the total dose of radiation used. This accounts for the described biphasic radiation injury.
