目的 :探讨小肠段代直肠的可行性。方法 :取带血管蒂回肠一段 ,一端回结肠端侧吻合 ,一端肛管吻合或外置 ,重建肛门括约肌术 15例。结果 :15例无吻合口瘘、肠坏死 ,无手术死亡。 13例括约肌成形功能良好。结论 :回肠血供丰富 ,系膜松解后 ,长度可满足重建直肠、内括约肌成形 ,技术可行 ,不增加手术难度 ,可保证吻合口血运 ,提高肿瘤根治率 ,减少术后并发症和局部复发 ,是理想的自体替代材料。
Objective: To explore the feasibility of rectum in the small intestine. Methods : Take vascular pedicle ileum, anastomosis of the end of the ileum colon, one end of the anal canal anastomosis or external, reconstruction of anal sphincter surgery in 15 cases. Results: There was no anastomotic leakage and intestinal necrosis in 15 patients. No operative death occurred. 13 cases had good sphincter forming function. Conclusion: The ileum has abundant blood supply. After the mesangial release, the length can satisfy the reconstruction of the rectum and internal sphincter. It is technically feasible. It can increase the blood supply of the anastomosis, increase the rate of tumor cure, and reduce postoperative complications and localization. Relapse is an ideal auto replacement material.
