目的 :探讨胰头癌切除范围对预后的影响。方法 :对比分析 95例胰头癌患者中 44例行经典胰十二指肠切除及 5 1例行扩大胰十二指肠切除的生存期、手术并发症和死亡率等。结果 :扩大切除组和经典切除组术后 1、3、5年存活率分别为 72 .5 %、45 %、17.5 %和 47.73%、19.35 %、6 .45 % ,两组间比较差异有显著性 ,扩大切除组 1、3、5年存活率较经典切除组明显提高 ( P<0 .0 5 ) ;两组手术并发症和死亡率分别为 2 9.41%、5 .88%和 2 5 %、4.5 5 % ,二者比较差异无显著性。结论 :扩大切除能改善胰头癌患者的预后 Objective: To investigate the effect of resection range of pancreatic head cancer on prognosis. Methods :Comparative analysis of survival time, surgical complications and mortality of 44 cases of pancreatic head cancer in 44 cases of classical pancreatoduodenectomy and 51 cases of extended pancreatoduodenectomy. Results: The 1-, 3-, and 5-year survival rates of the expanded resection group and the resection group were 72.5%, 45%, 17.5%, and 47.73%, 19.35%, and 6.4%, respectively. There was a significant difference between the two groups. In the expanded group, the 1-, 3-, and 5-year survival rates in the resection group were significantly higher than those in the classic resection group (P<0.05); the complications and mortality rates in the two groups were 29.41%, 5.88%, and 25%, respectively. , 4.55%, no significant difference between the two. Conclusion: Extended resection can improve the prognosis of patients with pancreatic head cancer
