为探讨壶腹周围癌影像学诊断及检查方法之选择，回顾性分析了２５例经手术病理证实的壶腹周围癌患者的影像学检查。结果：①十二指肠镜检结合逆行胰胆管造影对壶腹周围癌诊断符合率最高（８８．０％），其次为ＣＴ（５６．０％），Ｂ超（３６．０％），十二指肠低张造影（１２．０％）。②十二指肠镜检对乳头癌、十二指肠降部癌及逆行胰胆管造影对胆总管下端癌的诊断准确率最高；ＣＴ对胰头癌价值最大；Ｂ超检查对胆总管下端癌有很重要意义。低张十二指肠造影有助于发现十二指肠降部癌及胰头癌。在壶腹周围癌早期，要重视上腹饱胀不适、纳差、乏力等非特异性症状。及时行Ｂ超检查，而Ｂ超及ＣＴ还有助于显示肿瘤腔外侵犯的范围以及腹腔转移、血管受累等情况。这对于治疗方案及手术方式的选择有重要意义。
In order to explore the choice of imaging diagnosis and detection of periampullary carcinoma, the imaging examination of 25 cases of periampullary carcinoma confirmed by surgery and pathology was retrospectively analyzed. Results: ① The coincidence rate of duodenal biopsy and retrograde cholangiopancreatography in diagnosis of periampullary carcinoma was the highest (88.0%), followed by CT (56.0%), B (36.0%), Duodenal low contrast radiography (12.0%). ② duodenal biopsy of papillary carcinoma, duodenal hypogastric cancer and retrograde cholangiopancreatography on the diagnosis of the lowest common bile duct cancer, the highest accuracy; CT of pancreatic cancer is the most valuable; B ultrasound examination of the common bile duct cancer Very important. Low-duodenal angiography helps to detect duodenal descending carcinoma and pancreatic head cancer. Around the ampulla in early cancer, we should pay attention to abdominal discomfort, anorexia, fatigue and other non-specific symptoms. B-line ultrasound in a timely manner, and B ultrasound and CT also help to show the extent of extracavitary tumor invasion and abdominal metastasis, vascular involvement and so on. This is important for the choice of treatment options and surgical procedures.
