CT is a suitable method for evaluation of local recurrence of rectal carcinoma after abdomino-perineal resection, as the presence of a soft tissue mass in the presacral area may be due to either residual changes from the previous surgery, or recurring disease. CT guided fine needle aspiration biopsy with a transgluteal approach was a relatively simple and fast procedure for obtaining cytological proof on the nature of the lesion in 7 out of 9 patients.
CT是评估腹会阴联合切除术后直肠癌局部复发的合适方法，因为骶前区软组织肿块的出现可能是由于既往手术的残留改变，也可能是疾病复发。CT引导下经臀肌途径细针穿刺活检是一种相对简单快捷的方法，9例患者中有7例通过该方法获得了病变性质的细胞学证据。
