梗阻性左半结直肠癌术前支架减压与急诊手术248例

目的:评价梗阻性结直肠癌支架置入的安全性,比较支架减压后手术与急诊手术的短、长期效果.方法:回顾性分析2000-10/2008-02我院248例梗阻性左半结直肠癌手术患者的临床资料,按支架与否分为两组,统计结肠镜下留置结肠腔内支架本身的成功率及并发症情况.比较两组Ⅰ期切除吻合例数、吻合口漏、切口感染、脾撕裂、腹腔脓肿等短期并发症、住院期间死亡率及两组生存曲线.结果:内镜下留置结肠腔内镍钛记忆合金支架成功率98.4%,总的并发症发生率14.5%,其中严重并发症(穿孔、支架移位)发生率4.8%.Ⅰ期吻合支架组明显高于急诊手术组(87.1%vs 34.4%,P=0.001).总的并发症支架组明显低于急诊手术组(17.7% vs 47.3%,P=0.000).两组患者2年生存曲线几乎重叠,之后支架组生存率略高于急诊手术组,但两组生存曲线比较无统计学差异(P=0.497).结论:对于梗阻性左半结直肠癌患者.结肠镜下留置结肠腔内支架术前减压是一种比较理想的辅助方法,增加I期切除吻合机会,避免造口,降低短期并发症,长期生存率也较急诊手术有一定的提高.

Comparison of the outcomes of preoperative stent insertion and emergency surgery in the treatment of obstructive leftsided colorectal cancer: an analysis of 248 cases

AIM: To evaluate the efficacy and safety of self-expanding metallic stents (SEMSs) and to compare the short- and long-term outcomes of preoperative stent insertion and emergency surgery in the treatment of obstructive left-sided colorectal cancer. METHODS: Sixty-two patients who underwent SEMS insertion and 186 patients who underwent primary emergency surgery for left-sided colorectal cancer from 2000 to 2008 were retrospectively analyzed. RESULTS: The SEMSs were placed successfully in 61 patients, of which...
