摘　　要：目的总结彩色多普勒超声对胰头部肿块型慢性胰腺炎的诊断价值,分析误诊原因。方法对7例经手术病理证实的胰头部肿块型慢性胰腺炎和相关病变检查及误诊原因进行回顾性分析。结果超声对胰头部肿块型慢性胰腺炎定位诊断灵敏性、特异性、正确率分别为100%(6/6)、0%(0/1)、85.7%(6/7);超声定性诊断全部错误(7/7,100%);6例误诊为胰头癌,1例误诊为Vater壶腹周围癌。对胰头部肿块伴随病变胆囊肿大、胆总管和主胰管扩张诊断全部正确(7/7,100%);主胰管结石诊断正确率为75%(3/4);胆囊结石诊断正确率为100%。结论彩色多普勒超声对胰头部肿块型慢性胰腺炎定位诊断正确率较高,定性诊断困难,容易误诊为胰头癌。Objective To evaluate the role of color Doppler ultrasound in the diagnosis of 7 cases of focal chronic pancreatitis mimicking pancreatic head mass,and to analyze the causes of misdiagnosis.Methods The clinical data of 7 patients with focal chronic pancreatitis mimicking pancreatic head mass were reviewed and analyzed for the cause of misdiagnosis.Results The sensitivity,specificity,and accuracy of ultrasound for positioning diagnosis of the focal chronic pancreatitis presenting as a pancreatic head mass was 100% （6/6）,0% （0/1） and 85.7% （6/7）,respectively.The qualitative diagnosis was misdiagnosed in the patients （7/7,100%）.Six cases were misdiagnosed as pancreatic head cancer,1 case was misdiagnosed as ampulla of Vater cancer.Enlarged gallbladder,dilated common bile duct and main pancreatic duct were diagnosed correctly in all the patients （7/7,100%）.The diagnostic accuracy for the main pancreatic duct stone and gallstone was 75% （3/4） and 100% （3/3）,respectively.Conclusion Color Doppler ultrasonography has high accuracy in the positioning diagnosis of focal chronic pancreatitis mimicking pancreatic head mass,but the accuracy of qualitative diagnosis is poor.The lesions are prone to be misdiagnosed as pancreatic head carcinoma.
