抄録

This is a case report of a 85Ryear-old female with carcinoma in the cervix of the uterus.She was under radiotherapy (45 Gy of external irradiation and 20 Gy of internal irradiation)since April 199. In November of the same year, she noticed fresh blood on defecation. Colonoscopy was carried out on December 1, 2000, and a readily bleeding teleangiectatic lesion was detected in the anterior wall of the lower segment of the rectum and consequently she was diagnosed as havirlg radiation proctitis. For this lesion, argon plasma coagulation(APC)was carried out three times with 40 w of high frequency output and argon gas flow rate of 0.41/min to 0.61/min. After this treatment, only a small part of the teleangiectatic lesion remained with no more bleeding. Management of sueh lesion by this therapeutic modality involved less pain and very minimal invasiveness. Therefore, it was suggested that this therapy is effective for the treatment of readily bleeding teleangiectatic lesions such as class l Sherman radiation colitis.
