Radiation enteritis diagnosed by capsule endoscopy - 22/08/11
Doi : 10.1016/j.gie.2007.03.006
| Commentary Acute radiation enteritis, much like radiation injury to the esophagus or the colon, is characterized by hyperemia, edema, inflammatory cell infiltration of the mucosa, and ulceration. Vascular endothelial cells may degenerate, fibrin plugs may form, and, with the passage of time, obliteration of small blood vessels result in ischemic injury. By endoscopy, chronic radiation injury is characterized by telangiectasia, a plethora of neovascularity, with spiraled vessels scattered amidst an ulcerated epithelium. Enteroscopy, be it by push, capsule, or double-balloon technique, is well suited to discovering these lesions that, despite their diminutive size, can wreck havoc clinically. Bleeding foci of radiation telangiectasia that are localized can be treated by a variety of transendoscopic ablative techniques, whereas those that are diffuse require either pharmacologic or surgical therapy, as in this case.
