简介：　　【摘要】 目的 探讨直肠外翻切除吻合术治疗直肠癌的临床效果及应用价值。方法 以 2017年 1月—— 2019年 6月期间收治的 37例直肠癌患者为研究对象，对其临床资料进行回顾性分析，观察手术成功率、术后并发症发生率，随访五年，观察复发率及 5年生存率。结果 37例患者的手术均获成功，术后患者按照肛门节制大便功能评价，优 22例，良 12例，差 3例，优良率为 91.89%，无吻合漏、大便失禁等并发症发生， 5年内复发 3例，复发率为 8.10%， 5年观察期结束，生存 30例，生存率为 81.08%。结论 经直结肠外翻切除吻合术治疗直肠癌可有效治疗直肠癌，患者术后大部分控便能力良好，生活质量得到提高，并且复发率较低，五年生存率较高，具有较高的临床应用价值，可推广应用。  　　【关键词】 直肠癌外翻切除吻合术；直肠癌；临床分析  　 [Abstract] Objective To explore the clinical effect and application value of eversion resection and anastomosis in the treatment of rectal cancer. Methods the clinical data of 37 patients with rectal cancer from January 2017 to June 2019 were analyzed retrospectively. The success rate of operation, the incidence of postoperative complications, the recurrence rate and 5-year survival rate were observed. Results the operation of 37 cases was successful. According to the evaluation of anal continence, 22 cases were excellent, 12 cases were good, 3 cases were poor, the excellent and good rate was 91.89%. There was no anastomotic leakage, fecal incontinence and other complications. 3 cases recurred within 5 years, the recurrence rate was 8.10%, the 5-year observation period ended, 30 cases survived, the survival rate was 81.08%. Conclusion the treatment of rectal cancer with rectocellular eversion resection and anastomosis can effectively treat rectal cancer. Most of the patients have good defecation control ability, improved quality of life, low recurrence rate and high five-year survival rate. It has high clinical application value and can be widely used.
