目的 探讨经肛门结肠外翻拉出吻合在低位直肠癌保肛术中的价值。方法 2 7例患者肿瘤下缘距肛缘 5 .0～ 7.0cm ,按“无瘤术”原则清除与肿瘤相应的肠系膜及根部的淋巴结 ,经腹切除直肠癌 ,将近端结肠经肛门外翻拉出 ,与直肠断端在肛门外行一层吻合并回纳。结果 术后无瘤生存 2 5例 ,占 92 .6% ;局部复发和远处转移各 1例 ,各占 3 .70 % ;术后患者均较好地保持了正常的排便控制功能。结论 低位直肠癌经腹切除经肛门结肠外翻拉出吻合术是一种安全、经济、疗效可靠的术式。
Objective To investigate the value of anal sphincter preservation and anal sphincter preservation by anal anastomosis. Twenty-seven patients with tumor margin from the anal margin of 5.0 ~ 7.0cm, according to the principle of “tumor-free” clear the corresponding mesenteric and root lymph nodes, abdominal resection of the rectal cancer, the proximal colon by anal eversion Pull out, and rectal stump in the anus outside a layer of anastomosis and back satisfied. Results Tumor-free survival was found in 25 cases (92.6%) after surgery. One case had local recurrence and distant metastasis, accounting for 3.70% of all. Postoperative patients maintained normal defecation control function. Conclusions Transrectal resection of low rectal cancer via anorectal pull-out anastomosis is a safe, economical and reliable operative procedure.
