目的探讨磁共振成像(MRI)显示胆胰管汇合区域精细解剖结构及其变异的可行性和价值.方法研究纳入112例行上腹部MRI增强扫描的受检者,排除了临床及实验室检查证实有胰胆管疾病的患者.观察十二指肠乳头的位置、胆胰管汇合的方式,测量胆胰共同管或胆总管与十二指肠的夹角、胆胰管夹角.结果大乳头位于十二指肠降部上、中、下段者分别占17.0%、66.0%、17.0%,胆胰共同管或胆总管与十二指肠的夹角为44.4°;胆胰管在十二指肠壁内汇合占11.6%,壁外汇合占80.4%,分别注入占8.0%,胆胰管夹角为37.8°.结论 MRI能清晰显示胆胰管汇合特征,能较好显示胆胰管不同汇合方式的细微差别,为临床诊断及治疗胆胰管汇合区疾病提供精细的影像解剖信息.

Objective To explore the use of magnetic resonance imaging (MRI) in the display of detailed anatomical structures at the pancreaticobiliary junction. Methods 112 patients who received enhanced MRI of upper abdomen were included in the study. Patients with pancreatic and/or biliary diseases diagnosed clinically and with laboratory tests were excluded. The types of junction between the terminal common bile duct and the pancreatic duct, and the location of the major duodenal papilla were studied on MRI. We measured the angle between the duodenum and the common pancreaticobiliary duct or the common bile duct. Results Of the 112 patients, the duodenal papillas were located at the upper, middle, and lower segment of the duodenum in 17. 0%, 66. 0% and 17. 0%, respectively.The angle between the common pancreaticobiliary duct or the distal common bile duct and the descending duodenum was 44. 4°±17. 3°. The pancreatic duct and the common bile duct opened separately in 9 patients (8. 0%). The confluence of the two ducts was present inside and outside of the duodenum wall in 13 (11. 6%) and 90 patients (80. 4%), respectively. The angle between the distal common bile duct and the pancreatic duct was 37. 8°±15.1°. Conclusion MRI was able to display detailed anatomical structures of the pancreaticobiliary junction, including the angle of the junction between the two ducts and the location of the duodenal papilla. It has the ability to provide meticulous anatomical data for the diagnosis and treatment of diseases at the pancreaticobiliary junction and to help surgeons formulate operative plans.
