超声检查对先天性胆管囊状扩张症的诊断价值

目的探讨超声诊断先天性胆管囊状扩张症的价值。方法回顾性分析50例先天性胆管囊状扩张症患者的临床资料,分析超声检查对其的诊断价值。结果 50例先天性胆管囊状扩张症患者超声正确诊断48例,诊断符合率96.0%,误诊2例,1例Ⅰ型患者误诊为胰腺囊肿,1例Ⅴ型患者误诊为多发肝囊肿。44%患者合并结石,2%患者合并癌变,30%患者合并胆囊炎、胆囊结石。结论超声诊断先天性胆管囊状扩张症具有较高的诊断准确率,在诊断过程中为避免误诊、漏诊应注意鉴别诊断。

Diagnostic value of ultrasound in congenital cystic dilatation of bile duct

Objective To investigate the value of ultrasound in the diagnosis of congenital cystic dilatation of the bile duct. Methods The clinical data of 50 patients with congenital cystic dilatation of bile duct were retrospec- tively analyzed to summarize the diagnostic value of ultrasound. Results Among 50 cases, 48 cases were diagnosed correctly with ultrasound,the diagnostic accordance rate was 96.0%;2 cases were misdiagnosed, 1 case of type I was misdiagnosed as pancreatic cysts, and the another case of type V was misdiagnosed as multiple hepatic cysts. 44~ of the patients were complicated with bile duct stones, 2 % with cancer, 30 % with cholecystitis or gallbladder stones. Conclusion Ultrasound has the high accuracy rate in the diagnosis of congenital cystic dilatation of the bile duct, but the differential diagnosis should be noticed to reduce the misdiagnosis rate and the missed diagnosis rate during the diagnostic process.
