目的：探讨早期胰头－壶腹区癌的影像学表现及病理基础。材料与方法：分析４０例早期胰头－壶腹区癌的ＣＴ、十二指肠低张造影表现与超声比较。胰头癌１０例，胰腺段胆总管癌１５例，壶腹癌１５例。结果：ＣＴ检出胰头癌６例，胰腺段胆总管癌１１例，壶腹乳头癌９例，敏感性分别为６０％，７４％，６０％。超声检出胰头癌３例，敏感性４２％，１０例胰腺段胆总管癌和壶腹乳头癌超声未明确诊断。低张十二指肠造影检出壶腹癌１３例，敏感性８７‰。结论：ＣＴ和十二指肠低张造影检查为早期胰头壶腹区肿瘤的最佳影像学检查方法。
Objective: To investigate the imaging features and pathology of early pancreatic-ampullary carcinoma. MATERIALS AND METHODS: CT and duodenal low contrast radiography were compared with ultrasound in 40 cases of early stage pancreatic ampulla of carcinoma. Pancreatic cancer in 10 cases, 15 cases of common bile duct cancer, 15 cases of ampulla. Results: CT was detected in 6 cases of pancreatic head cancer, 11 cases of common bile duct cancer in the pancreas, and 9 cases of ampullary papillary carcinoma. The sensitivity was 60%, 74% and 60% respectively. Ultrasound detection of pancreatic cancer in 3 cases, the sensitivity of 42%, 10 cases of pancreatic cholangiocarcinoma and ampullary papillary carcinoma ultrasound is not specifically diagnosed. Low-lying duodenal angiography detected 13 cases of ampulla, the sensitivity of 87 ‰. Conclusion: CT and duodenal low contrast angiography is the best imaging method for early stage pancreatic ampulla area tumor.
