目的为了寻找影响直肠癌腹会阴切除术疗效的因素和探索提高术后生存率的途径。方法回顾分析我院1964～1994年804例直肠癌腹会阴切除术后的远期效果。结果全组手术死亡率为0.7％,随访率98.8％。术后5、10、15、20、25年生存率分别为53.2％、44.5％、43.1％、42.3％和40.5％。结论直肠癌腹会阴切除术后生存率与年龄、肿瘤大小、大体类型、术前并发症、淋巴结转移、病期等有关。其中,淋巴结转移和病期是最主要因素。
Objective To find the factors influencing the curative effect of rectal resection of rectal cancer and explore ways to improve the postoperative survival rate. Methods The long-term results of 804 cases of rectal cancer after perineal resection in our hospital from 1964 to 1994 were retrospectively analyzed. Results The operative mortality rate was 0.7% in the whole group, and the follow-up rate was 98.8%. The survival rates at 5, 10, 15, 20, and 25 years after surgery were 53.2%, 44.5%, 43.1%, 42.3%, and 40.5%, respectively. Conclusion The survival rate of rectal cancer after perineal resection is related to age, tumor size, gross type, preoperative complications, lymph node metastasis, and stage of disease. Among them, lymph node metastasis and stage are the most important factors.
