Overview
Radiation proctitis 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. 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.

Treatment
Medical Therapy
Acute radiation proctitis is a self limiting condition and treated conservatively however in 20% of cases undergoing external beam radiation will require short interruptions in their treatment to improve symptoms.In case of chronic radiation proctitis treatment usually depends upon the severity and pattern of the symptoms.
Surgery
Surgery is not the first-line treatment option for patients with radiation proctitis.However it is usually reserved as a last resort for patients with refractory symptoms and complications.
Prevention
Primary prevention of radiation proctitis can be done by the modifications of radiation techniques and doses or by use of prophylactic adjunct medical and surgical therapies.
