摘　　要：目的使用多因素分析方法，探讨超声对局限性胰腺炎与胰头癌的鉴别价值。方法局限性胰腺炎35例，胰头癌32例，观察胰头肿物的二维声像图及彩色多普勒血流的表现，将单因素分析得出的与胰头肿块有关的变量进行回归统计，采用logistic逐步回归法进行多因素分析。结果胰头肿块在形态、边界、内部回声、主胰管扩张、胆总管扩张、血流分级及阻力指数均存在统计学差异（P〈0．05）．将这些变量进行回归统计，显示肿块形态、边界、主胰管扩张、胆总管扩张及血流分级进入回归模型。结论彩色多普勒超声对局限性胰腺炎与胰头癌有重要的鉴别诊断价值。Objective To explore the clinical value of ultrasound in differentiating of local panereatitis （LP）and carcinoma of head of pancreas （CHP） by multiplicity. Methods Thirty five patients with LP and 32 patients with CHP were enrolled in this study. Two dimensional sonogram and color Doppler blood flow appearanee of CHP were analysed, the resuhs was analyzed by multivariate logistic regression. Results There were significant differences in the shape, edge, internal echo, common bile duct expandsion, main pancreatic duct expandsiun, blood classification and RI（P〈0.05）. These variance were analyzed by muhivariate logistic regression. The shape, edge, internal echo, common bile duct expandsion, main pancreatic duct expandsion and blood flow classification were seleeted into the logistic modelity. Conclusion There are significant （differences between local panereatitis and carcinoma of head of panereas in two dimensional ultrasound and color Doppler blood flow.The shape, edge, internal echo, common bile duel expandsion, main pancreatic duct expandsion and blood flow classification were seleeted into the logistic regression are has important value in diagnosis and differential diagnosis.
