【摘要】 目的 探索腹腔镜全直肠系膜切除(TME)低位、超低位前切除治疗低位直肠癌的可行性。方法 按TME原则、用双钉合术(DST)，在腹腔镜下对16例低位直肠癌患者实施TME、DST低位、超低位结肠-肛管吻合术。结果 手术时间110～210min，平均145min；术中出血15～80ml，平均35ml；术后1～2天恢复胃肠功能并下床活动，住院时间6～15天，平均9天。16例患者手术顺利。术后疼痛剂应用6例，1例尿潴留外，其余患者未见术中及术后并发症。结论 腹腔镜TME、低位、超低位吻合术治疗低位直肠癌，创伤小、保肛率高、术后疼痛轻、恢复快，是极具应用前景的微创技术。

    【Abstract】 Objective To assess the feasibility of laparoscopic total mesorectal excision(TME) for low or ultralow anterior resection or rectal cancer.Methods Excision of the mesorectum and low(ultralow)colo-anal anastomoses were performed laparoscopically in 16 patients with low rectal cancer based on the concept of TME and double stapling technique(DST).Results 16 operations with TME and DST were performed in a totally laparoscopic manner，and only one was converted to open procedure because of dysfunction of coagulation.The operative time was 145 min(110～210min)and the operative blood loss 35ml(15～80ml).The time for bowel function recovery and post-operatively dietary intake was 1～2 days.Twenty patients received postoperative analgesics.Average hospital stay was 9 days(6～15days).Complications were observed in only 6 of the 62 patients ......
