Abstract
目的 分析胰十二指肠切除术后胰瘘的危险因素,探讨黏膜-黏膜胰肠吻合减少术后胰瘘的可能性.方法回顾性研究我院2000年1月至2004年4月间85例胰十二指肠切除术病例,分析影响胰瘘的术前及术中危险因素,比较不同胰肠吻合方式对胰瘘的影响.结果术后胰瘘总发生率16.5%(14/85),其中黏膜-黏膜组3.57%(1/28),传统套入组22.8%(13/57).统计学分析显示,胰肠吻合方式、胰管直径及残余胰腺质地为影响胰瘘发生的显著因素;多因素Logistic回归分析表明,胰管直径和胰腺质地为影响胰瘘发生的独立危险因素,P值分别为0.013和0.009,相对危险度(OR)分别为5.276和8.538.结论胰肠吻合方式、胰管直径和胰腺质地是影响胰十二指肠切除术后胰瘘的危险因素,对胰管扩张者(≥3 mm)行黏膜-黏膜吻合可显著降低术后胰瘘的发生率,是一种安全可靠的胰肠吻合方法。
