［目的］探讨管状吻合器在低位直肠癌术中应用的临床意义。［方法］1989年～1998年对17例低位直肠癌行Dixon’s手术中应用管状吻合器作结肠-直肠的端端吻合。［结果］17例中除发生2例吻合口狭窄、2例粪便控制不佳外，其余均满意。［结论］管状吻合器在低位直肠癌术中使用安全可靠，简便快速，并发症少，尤其低位直肠吻合的优势更为手法缝合所不及。 [Objective] To explore the clinical significance of tubular stapler in the application of low rectal cancer. [Methods] From December 1989 to 1998, 17 cases of low rectal cancer underwent Dixon’s operation using a tubular stapler for end-to-end anastomosis of the colon and rectum. [Results] Except for 2 cases of anastomotic stenosis and 2 cases of poor feces control, 17 cases were all satisfactory. [Conclusion] Tubular stapling device is safe, reliable, simple and rapid, and has few complications in the operation of low rectal cancer. In particular, the advantage of low rectal anastomosis is less than that of maneuvering.
