目的：为探讨体表超声判断胆管癌浸润胰腺、十二指肠的可能性、诊断标准及诊断率，并完善胆管癌超声分期研究。方法：观察肿瘤的发生部位，与胰、十二指肠的边界关系等，分析３５例手术病理确诊的下段胆管癌（包括壶腹癌１８例）对周围组织浸润的诊断结果。结果：确定了超声对胆管癌浸润胰腺的诊断标准，分为Ｐａ１－Ｐａ３三个程度。另确定了超声对胆管癌浸润十二指肠的诊断标准，分为Ｄｕ（－）、Ｄｕ（＋）两个程度。对照手术及病理结果，超声对胰腺浸润诊断正确率达７４％；对十二指肠浸润诊断正确率仅为３５％。结论：超声对胆管癌胰腺浸润的诊断率较高，对十二指肠浸润诊断有一定局限性。
OBJECTIVE: To investigate the possibility of surface ultrasound to determine the infiltration of the pancreas and duodenum by cholangiocarcinoma, the diagnostic criteria and diagnostic rate, and to improve the ultrasound staging of cholangiocarcinoma. Methods: Observing the location of the tumor, the relationship with the pancreas and the duodenum, etc. The diagnosis results of 35 cases of lower cholangioma (including ampulla of the ampulla of 18 cases) confirmed by surgical pathology were analyzed. RESULTS: The diagnostic criteria for ultrasound-induced cholangiocarcinoma invasion of the pancreas were determined and divided into Pa1-Pa3 levels. In addition, the diagnostic criteria of ultrasound for cholangiocarcinoma infiltrating the duodenum were defined and divided into Du(-) and Du(+) levels. With regard to surgical and pathological results, the diagnostic accuracy of pancreatic infiltration by ultrasound was 74%; the diagnostic accuracy of duodenal infiltration was only 35%. Conclusion: Ultrasound has a high diagnostic rate for pancreatic infiltration of cholangiocarcinoma, and has some limitations in the diagnosis of duodenal infiltration.
