摘要
目的 探讨低位直肠癌保肛手术的适应证 ,术式选择及疗效。方法 回顾性分析手术后≥ 5年的 3 2 0例低位直肠癌行保肛手术治疗患者的临床资料 ,比较各种术式的 5年生存率、局部复发率及死亡率。结果 低位直肠癌保肛率为 5 8.5 % ( 3 2 0 / 5 47)。术后发生吻合口漏为 4例 ( 1.2 5 % ) ,1年内吻合口狭窄发生 2 6例 ( 8.13 % ) ,术后排便情况以加做结肠末端粪袋成形术者为佳。 5年生存率及吻合口局部复发率 :Dixon手术组为 63 .2 4% ,10 .2 7% ;Park手术组为 66.67% ,5 .13 % ;局部切除手术组为 89.46% ,10 .71%。 5年盆腔软组织复发 11例 ( 3 .44 % )。全组手术死亡 2例 ( 0 .6% )。结论 低位或超低位结肠 -直肠吻合术是低位直肠癌保肛手术的主要术式。在严格掌握适应证的情况下 ,可考虑施行低位直肠癌的局部切除术。低位直肠癌保肛手术并不影响 5年生存率和局部复发率 ,术后并发症的发生与术式选择无关 ,辅助性的结肠末端粪袋成形术 ,有利于改善低位直肠癌保肛术后的排便功能。
Objective To evaluate the indication,operation pattern and therapeutic effect of ano-saving surgery for lower rectal carcinoma. Methods Retrospective analysis on the clinical feature of 320 patients with lower rectal carcinoma (postoperative time ≥5 years)treated by ano-saving surgery, the 5-year survival rate, local recurrence rate, and mortality were compared in the various operations. Results The success performed rate of ano-saving operation for lower rectal cancer was 58.5%(320/547).Among them, anastomotic leakage after surgery occurred in 4 cases (1.25%), and 26 cases had anastomostic narrowness (8.13%) within 1 year after surgery.The defecation function after surgery, in patients received colonic J pouch or transverse coloplasty pouch was much better than that in patients received coloanal or colorectal anastomosis. 5-year survival rates, and anastomostic recurrence rates were as follows:In ultra-low anastomosis were 63.24% and 10.27%. Park′s operation 66.67% and 5.13%, local resection 89.46% and 10.71%, respectively. 5-year recurrence rate in the pelvic soft tissue was 3.44%(11/320).Two cases died after operation. Conclusions Lower or ultra-low colon-rectum anastomosis becomes the main operative pattern in preserving anal sphincter in lower rectal cancer.Local resection of lower rectal tumor might be considered if the indecation is selected strictly. Colonic-J-pouch or transverse coloplasty pouch is good for improving the defecation function after ano-saving surgery for lower rectal cancer.
