报道１９８６年１月～１９９４年１２月间收治直肠癌患者７８３例，其中，中下段直肠癌５５２例（占７０．５％）。该５５２例中施行各类保肛术２０１例（占３６．４％），其中经腹骶切除５例，经耻骨切除５例，Ｄｉｘｏｎ式６７例，拉下式吻合４４例，拖出式吻合６８例及局部切除１２例。术后３年生存率达９０．９％。文中就保肛手术的根治性、术后排便功能的恢复、并发症的产生和处理以及综合治疗的必要性等问题进行了分析讨论。认为保肛术是治疗中下段直肠癌的一种合理术式，其主要适用于Ｄｕｋｅ’ｓＡ和Ｂ１期病例。采取综合治疗则是预防癌肿复发和提高生存率的重要措施。
Reported 783 cases of rectal cancer patients from January 1986 to December 1994, including 552 cases of middle and lower rectal cancer (70.5%). In these 552 cases, 201 cases (36.4%) of all types of anus-preserving procedures were performed. Among them, 5 cases were treated by abdominal hernia resection, 5 cases were treated by pubic resection, 67 cases were Dixon type, and 44 cases were pull-down anastomosis. 68 cases and local resection in 12 cases. The 3-year survival rate was 90.9%. This article analyzes and discusses the problems of the sphincter preservation surgery, the recovery of postoperative defecation function, the generation and treatment of complications, and the necessity of comprehensive treatment. It is considered that sphincter preservation is a reasonable surgical treatment for middle and lower rectal cancer, and it is mainly applicable to Duke’s A and B1 cases. Comprehensive treatment is an important measure to prevent cancer recurrence and improve survival.
