摘要:
目的:比较急诊超声与CT对腹部钝性伤所致胰腺损伤的诊断价值。方法:对10例经临床和手术证实的腹部钝性伤致胰腺损伤的超声及CT检查结果进行对照分析。结果:10例胰腺损伤中:超声术前诊断其中6例,直接征象包括腺体局部回声减低、腺体中断、假性囊肿等,4例漏诊;共6例接受CT检查(包括B超漏诊的3例),CT术前诊断其中5例,直接征象包括胰腺增粗,胰腺腺体内出现低密度、混杂密度或稍高密度区,胰腺外形不连续、或出现垂直胰腺长轴的带状低密度影,1例漏诊;间接征象包括胰周积液、网膜囊积液、腹腔积液等。结论:急诊超声对胰腺损伤的初步诊断可以提供帮助,结合B超、CT检查则能够对胰腺损伤的情况作出更准确地判断。
Abstract:
Objective:To compare emergency ultrasonography (US) with computed tomography (CT) in detection of pancreatic injury from blunt abdominal trauma.Method:US and CT findings of 10 patients with surgical proved pancreatic injury from blunt abdominal trauma were reviewed respectively.Results:In 6 patients diagnosised by US,the direct signs were the focal low-echoic zone,the broken pancreatic contour,pseudocyst.Other 4 patients were misdiagnosised by US.6 patients were examined by CT.In 5 patients diagnosised by CT,including 3 patients misdiagnosised by US,the direct signs were localized hypoattenuating area,mixed attenuation or slightly hyperattenuating lesions,the broken pancreatic contour,hypoattenuating linear findings across the pancreas vertically.The indirect signs were peripancreatic fluid collections,effusion of omental bursa and effusion of abdominal cavity.1 patient was misdiagnosised by CT.Conclusion:Emergency abdominal US can give some help in the first diagnosis of pancreatic injury,while CT can assess pancreatic injury more accurately.
