目的总结直肠拖出单吻合器保肛术治疗低位直肠癌的体会。方法对28例低位直肠癌,采用直肠拖出,直视下间断缝闭直肠断端或用荷包钳关闭直肠断端,用单吻合器施行直肠,乙状结肠端端吻合术。结果28例患者均成功地保留了具有控制排便功能的肛门,术后发生吻合口瘘1例,随访1~5年,1例于术后1年局部复发。结论直肠拖出单吻合器保肛术不但较双吻合器保肛术经济,而且同样是安全可靠行的。 Objective To summarize the experience of rectal pulling out single stapler sphincter for the treatment of low rectal cancer. Methods Twenty-eight cases of low rectal cancer were treated with rectal pull-out. The rectum was severed intermittently under the direct vision or the rectal stump was closed with a pincette. The anastomosis of the rectum and sigmoid colon was performed with a single stapler. Results All the 28 patients successfully retained the anus with defecation control function. One case had anastomotic fistula after operation, followed up for 1 to 5 years and 1 case had local recurrence 1 year after operation. Conclusion Rectal pull out single stapler sphincter preservation surgery is not only more economical than the double stapler, but also safe and reliable.
