[目的]探讨直肠拖出双吻合器保肛术在超低位直肠癌的临床应用价值。[方法]1999年1月～2006年12月对21例超低位直肠癌采用直肠拖出双吻合器技术行保肛手术切除。[结果]全组21例患者手术均获得成功,术后发生吻合口瘘1例,发生率为4.8%。术后控便功能优12例、良8例、差1例,术后肿瘤复发3例(14.3%),出现吻合口狭窄3例(14.3%),无手术死亡。[结论]直肠拖出双吻合器技术行超低位直肠癌保肛术能较好保留排尿、排便及性功能,提高了超低位直肠癌保肛手术的成功率。
[Objective] To investigate the clinical value of rectal pull-out double stapler anal sphincter preservation surgery in ultra-low rectal cancer. [Method] From January 1999 to December 2006, 21 cases of ultra-low rectal cancer were treated with rectal pull-out double stapling technique. [Results] All the patients in 21 cases were operated successfully. One case of anastomotic fistula occurred after operation, the incidence was 4.8%. Postoperative bowel control was excellent in 12 cases, good in 8 cases and poor in 1 case. Postoperative tumor recurrence in 3 cases (14.3%) showed anastomotic stenosis in 3 cases (14.3%) without operative death. [Conclusion] Rectal pull-out double stapling technique for ultra-low rectal cancer with anal sphincter preserves urination, defecation and sexual function, and improves the success rate of anus preservation in ultra-low rectal cancer.
