为了探讨直肠癌Ｍｉｌｅｓ术后会阴部肿块的诊断和治疗，作者回顾性分析了１９８６～１９９４年间住院治疗的５６例直肠癌Ｍｉｌｅｓ术后会阴部肿块病人。结果显示：①病因有慢性炎性肉芽组织增生４３例（７６．８％），局部肿瘤复发１３例（２３．２％）；②ＣＴ、穿刺细胞学检查、ＣＥＡ检测和放免显像技术对该病有诊断价值；③５６例中完整切除会阴肿块５１例，姑息性切除３例，未能切除２例，手术切除率９１．１％（５１／５６）。作者认为：直肠癌Ｍｉｌｅｓ术后会阴部肿块最常见的原因是慢性肉芽组织增生；对会阴部肿块性质的诊断要结合临床及检查结果综合分析，治疗要慎重，且勿盲目手术；加强围手术期管理，术中规范操作以及保证会阴部的切除范围是预防直肠癌术后会阴部肿块及肿瘤局部复发的关键
In order to investigate the diagnosis and treatment of perianal masses after Miles’ surgery for rectal cancer, the author retrospectively analyzed 56 patients who had been treated with Miles postoperative Miles postoperatively from 1986 to 1994. The results showed that: 1 The cause was chronic inflammatory granulation tissue hyperplasia in 43 cases (76.8%), local tumor recurrence in 13 cases (23.2%); 2 CT, aspiration cytology, CEA detection and radioimmunoassay for the disease There were diagnostic values; in 356 cases, there were 51 cases of complete resection of perineal mass, 3 cases of palliative resection, and 2 cases of failure to be removed. The rate of surgical resection was 91.1% (51/56). The authors believe that the most common cause of perineal mass after rectal cancer Miles is chronic granulation tissue hyperplasia; the diagnosis of the nature of the perineal mass should be combined with the clinical and comprehensive analysis of the results, treatment should be careful, and do not blindly surgery; strengthen the perioperative period Management, intraoperative and standard operation and guaranteeing the scope of resection of the perineum are the key to preventing the perineal mass and local tumor recurrence after rectal cancer surgery
