Radiation damage to small bowel tissue can cause acute or chronic radiation enteritis producing symptoms such as pain, bloating, nausea, faecal urgency, diarrhoea and rectal bleeding which can have a significant impact on patient's quality of life. This review outlines the pathogenesis ...
Radiation ileitis is rare as an isolated finding but frequently is associated with severe rectosigmoid damage. Surgical treatment is seldom necessary but, if indicated (ten patients), resection appears to be preferable to bypass. 展开 被引量: 93 ...
Chemotherapy with radiation augments radiation damage to bowel ○ Pathogenesis (2 methods) – Direct cytotoxic effect: Radiation → free radicals interact with DNA → elimination of replication, transcription, and protein synthesis→ cell disruption and death – Ischemic changes: Medial wall thickening an...

Clinical assessment of patients with radiation damage to the intestinal or genitourinary tract can be difficult. The symptoms may be similar to those of recurrent tumour. Radiology can be useful to document the presence and extent of any abnormality and to attempt to distinguish between radiation cha...
3. Pathophysiology of Radiation-Induced Bowel Injury 3.1. Cellular Effect of Radiation Ionising radiation carries enough energy to release electrons from atoms or molecules that are then capable of cell damage and death by several mechanisms. Detailed review articles of the effect of radiation on the...
Damage to the bowel and later consequences are increased by several different factors, some of which can be modified.44 Normally the intestine, except for the rectum, is constantly moving during the application of radiation. This diminishes the point exposure time of any one segment and decreases...
Radiation therapy is administered to approximately one third of patients with cancer as part of their treatment plan. Radiation-induced bowel injury is a major cause of morbidity in these patients. The pathophysiology of this condition as well as recommendations for the management of acute and chroni...
