Antecedentes:
La colitis actínica es una endarteritis obliterante ocasionada por exposición a radiación ionizante. Se manifiesta de manera aguda (primeras semanas) o crónica (hasta 30 años después).
Caso ClíNico:
Paciente tratado por neoplasia rectal mediante quimiorradioterapia y amputación abdominoperineal. En su estudio por cuadros oclusivos se objetiva una estenosis colónica desde la colostomía hasta el ángulo hepático. Se lleva a cabo cirugía resectiva, con resultado favorable.
Conclusiones:
En los próximos años es previsible un aumento en la incidencia de esta patología. Resultará fundamental establecer un nivel de sospecha que nos permita detectar los casos, así como establecer medidas que prevengan su aparición.
Background:
Radiation colitis is a obliterans endarteritis caused by exposure to ionizing radiation. It manifests early or late in time.
Case Report:
We present a case of rectal cancer treated with chemoradiotherapy and abdominoperineal resection ten years before. Patient suffered occlusive periods and colonoscopy showed stenotic colon extending from the colostomy up hepatic flexure. Colonic resection surgery was performed.
Conclusions:
It will be essential to establish a high level of suspicion that allows us to detect cases and it also will be essential to establish measures to prevent its occurrence.
