Real-time B-mode ultrasonic scanning was performed during 14 operations for pancreatic tumors. All operations were for adenocarcinoma, except in one patient with a Zollinger-Ellison tumor. The ultrasonic tissue appearance of pancreatic carcinoma was not specific. However, ultrasonic signs of pancreatic duct dilation, striction or invasion of the superior mesenteric veins, and common bile duct involvement may help to establish the diagnosis of malignancy. A triad of ultrasound signs indicative of malignant obstruction of the common bile duct consisted of (1) dilation, (2) absence of biliary stones, and (3) a distinctive termination pattern of the duct. Operative ultrasound was used to guide a biopsy needle to obtain pancreatic tissue samples. The Zollinger-Ellison tumor of the pancreas produced a sonolucent appearance that clearly distinguished it from the surrounding tissue.
在14例胰腺肿瘤手术过程中进行了实时B超扫描。除1例患有佐林格-埃利森肿瘤的患者外，所有手术均针对腺癌。胰腺癌的超声组织表现不具有特异性。然而，胰管扩张、肠系膜上静脉狭窄或侵犯以及胆总管受累的超声征象可能有助于确立恶性肿瘤的诊断。提示胆总管恶性梗阻的三联超声征象包括：（1）扩张；（2）无胆结石；（3）导管独特的终止模式。术中超声用于引导活检针获取胰腺组织样本。胰腺的佐林格-埃利森肿瘤呈现出无回声外观，这使其与周围组织明显区分开来。
