经肛门外翻双吻合器保肛术治疗低位直肠癌的临床研究

目的:评价经肛门外翻双吻合器保肛术治疗低位直肠癌的手术方法及疗效。方法:对经肛门外翻双吻合器保肛术治疗低位直肠癌30例患者的临床资料进行分析。结果:30例低位直肠癌患者均保留肛门。无手术死亡,术后发生切口感染3例,吻合口瘘2例。术后4周能预知和控制排便。术后6个月,每日排便1～4次者25例,5例偶有粪便外溢。随访6～70个月,吻合口狭窄1例,局部复发2例,中位生存期23.5个月,1、3和5年生存率分别为88%、68%和48%。结论:经肛门外翻双吻合器保肛术治疗低位直肠癌具有操作简单、安全等优点,能提高患者生存质量。

Sphincter preservation operation with eversion through anns combined with double stapler technique for low rectal cancer

OBJECTIVE: To evaluate the effect of eversion-through combined with double stapling technique for sphincter preservation operation in low rectal carcinoma.METHODS: Eversion-through combined with double stapling technique for sphincter preservation operation was performed on 30 patients with low rectal carcinoma.The clinical data was analyzed retrospectively.RESULTS: Fecal continence was preserved successfully in all patients.There was no operative death.Two cases got anastomosis leak and 3 cases had incision infection after operation.All patients could sense stool and control defecation in 4 weeks after operation.There were 25 cases with 1~4 defecations every day,5 cases with occasional overflow incontinence after half a year.All patients were followed upfrom 6 to 70 months.One case got anastomotic stenosis,2 cases got local recurrence,the median survival time was 23.5 months.The overall 1-,3-and 5-years survival rates were 88%,68% and 48% respectively.CONCLUSION: Eversion-through combined with double stapling technique for sphincter preservation operation is simple and safe for low rectal carcinoma,and can enhance the quality of life.
