目的观察超低位直肠癌根治极限保肛术式的临床效果。方法对25例超低位直肠癌患者经腹前会阴入路根治极限保肛,术中将血供良好的结肠断端无张力拉下与肛管吻合(行吻合器低位切除吻合)。结果所有患者均治愈出院,切缘均经病理证实无肿瘤细胞浸润,2例切口感染,3例吻合口瘘,两年内随访吻合口无肿瘤复发,远期肛门功能恢复良好。结论超低位直肠癌患者的根治、保肛手术,必须经过严格检查与选择。经腹前会阴入路,采用双吻合器根治性低位切除吻合保肛。这种术式能够保存患者肛门的功能,促使其正常功能的恢复,提升远期生存质量。 Objective To observe the clinical effect of anal sphincter preservation in ultra-low rectal cancer. Methods Twenty-five patients with ultralow rectal cancer were treated with anterior perineal approach to cure the anal sphincter. The intraoperative anastomosis of anastomosed lower end of the colonic anastomosis was performed without pulling down the blood supply. Results All the patients were cured and discharged. The margins were confirmed by pathology without tumor cell infiltration. Two cases were infected by incision and three cases were anastomotic fistula. There was no tumor recurrence in the follow-up anastomosis within two years and the long-term anal function recovered well. Conclusion Ultra-low rectal cancer patients radical, anal sphincter preservation, must undergo a rigorous examination and selection. The anterior perineal approach, the use of double stapling low radical resection anastomosis anus. This procedure can save the patient’s anus function, to promote the restoration of its normal function, improve long-term quality of life.
