摘要

44位經證實之胰臟癌病患接受腹部超音波檢查，其中40位病人可由超音波描繪出其胰臟形象。超音波正確診斷為胰臟癌者共36位(佔90%)。其超音波診斷根據以胰臟局部膨大(100%)為最常見之直接病徵。腫瘤部份之囘音類型以均勻低囘音型較為常見(佔83.4%)，其餘的腫瘤(16.6%)囘音類型為不均勻低囘音型。膽道系統披張為超音波診斷胰臟癌常見的間接病徵，特別是位於胰臟頭部之癌症(100%均有此病徵)。胰管擴張亦常見於胰臟頭部之癌症(54%有此病徵)。14位肝臓內有轉移性結節者，其囘音類型以低同音型最多，佔12位(86%)；其餘的間接病徵有：淋巴腺病變，血管移位，及腹水。
22位病人接受超音波指引下細針吸取細胞診，其中19位(86.4%)得到正確診斷。所有病例皆無併發症。
診斷胰臟癌時，腹部超音波檢查與細針吸取細胞診是安全，可靠且不可或缺的步驟。

Abdominal sonography was performed in 44 patients with proven pancreatic cancer. The pancreas was successfuly demonstrated in 40 patients. Thirty six patients were correctly diagnosed by sonography. The predominant direct sign of pancreatic cancer in sonography was localized enlargement of the Pancreas (100%). Most tumors showed homogeneous hypoechoic pattern (83.4%), and the remainings (16.6%) showed heterogeneous hypoechoic pattern. Dilated biliary system was the most common indirect sign in diagnosing pancreatic cancer, especially in cancer of the head (100%). Dilated pancreatic duct was also observed in 54% of patients with cancer of pancreatic head. Twelve of 14 patients (86%) with metastatic nodules in the liver were hypoechoic. Lymphadenopathy, displacement of blood vessels, and ascites were also valuable indirect signs. Twenty-two patients received echo-guided aspiration cytology of the pancreas, nineteen patients (86.4%) were correctly diagnosed. None of them had complications. It was concluded that abdominal sonography and fine-needle aspiration of the pancreas are safe, reliable and indispensable procedure in the diagnosis of pancreatic cancer.
