CT扫描诊断直肠癌术后局部复发

CT scanning in the diagnosis of local recurrences of postoperative rectal cancer

本院1987年以来 CT 扫描诊断为直肠癌术后盆腔内复发23例,吻合口复发8例,其中经手术与病理学诊断证实29例复发。CT 确诊率为93.5%,检出肿瘤大小2～8 cm,其中6例无复发临床表现。CT 所见:(1)骶前区单发分叶状或结节状肿块,或多发性肿块。(2)新直肠腔不规则偏心肿块或肠腔狭窄。(3)肿瘤侵及膀胱、卵巢、前列腺、骶尾骨、精囊或盆壁肌肉的征象。CT 是当前诊断盆腔内复发的较敏感、准确的工具。

Since 1987,23 cases of postoperatively recurring rectal cancer in the pelvis and 8 cases of such malignancy recurring at the site of anastomosis have been diagnosed through CT scanning.Of the 31 cases,29(93.5%)have been confirmed surgically,and pathologically.The size of the turnouts detected ranged from 2～8cm.Of the 29 cases confirmed,6 cases had no clinical manifestations of recurrence.The CT scanning findings included:(1) Mono-segmented or nodular masses in the sacre-anterior region,or multiple masses.(2)Irregular eccentric masses in the new rectal cavity, or stenosis of the rectal cavity.(3)Signs of invasion of the urinary bladder,ovary,prostate gland,scroccyx,seminal vesicle or muscles of the pelvic wall by the tumour.At present,CT scanning is a relatively sensitive and accurate means in the diagnosis of recurrences in the pelvic cavity.
