为寻找直肠癌腹会阴切除术后局部复发的可靠诊断方法，我们对２５例直肠癌腹会阴切除术后ＣＴ示盆腔、会阴肿块的病例采用ＣＴ引导下穿刺细胞学检查，１７例见腺癌细胞，确诊复发。８例未见癌细胞，其中２例行会阴肿块切除术，病理证实复发，６例定期复查ＣＴ，３例盆腔肿块逐渐增大，临床诊断复发，３例未经任何治疗盆腔肿块明显缩小，临床诊断术后纤维变。本组穿刺诊断阳性率７７％。ＣＴ引导下穿刺细胞学检查对诊断直肠癌腹会阴切除术后局部复发是一·种安全、可靠、有价值的诊断方法。
In order to find a reliable diagnosis method for local recurrence of rectal cancer after perineal resection, CT-guided puncture cytology was performed on 25 cases of rectal cancer after abdominal perineal resection and CT showed pelvic and perineal masses. Adenocarcinoma cells were seen in 17 cases. , confirmed recurrence. No cancer cells were found in 8 cases, of which 2 cases underwent perineal mass resection, pathology confirmed recurrence, 6 cases were regularly reviewed CT, 3 cases of pelvic masses gradually enlarged, clinical diagnosis of recurrence, 3 cases without any treatment of pelvic mass was significantly reduced, clinical Diagnosis of postoperative fibrosis. The puncture diagnosis rate in this group was 77%. CT-guided puncture cytology is a safe, reliable, and valuable diagnostic method for diagnosing local recurrence after rectal rectal resection of rectal cancer.
