Radiation proctitis (and the related radiation colitis) is inflammation and damage to the lower parts of the colon after exposure to x-rays or other ionizing radiation as a part of radiation therapy.[1] Radiation proctitis most commonly occurs after treatment for cancers such as cervical cancer, prostate cancer, and colon cancer. Radiation proctitis involves the lower intestine, primarily the sigmoid colon and the rectum and is part of the conditions known as pelvic radiation disease and radiation enteropathy.[2]
Radiation proctitis can occur at two times after treatment:
Symptoms such as diarrhea and painful defecation may be treated with oral opioids and stool softeners, respectively. Complications such as obstruction and fistulae may require surgery. Several other methods have been studied in attempts to lessen the effects of radiation proctitis. These include sucralfate, hyperbaric oxygen therapy, corticosteroids, metronidazole, argon plasma coagulation, and radiofrequency ablation.[1][2]
