To study the correlation between the angle of the pancreaticobiliary junction (APJ) and the prevalence of acute pancreatitis using magnetic resonance cholangiopancreatography (MRCP).
From February 2014 to October 2014, thirty two subjects with normal pancreas (group A) and 40 patients with acute pancreatitis (group B) who underwent MRCP were enrolled into our study. The type of biliary duct and main pancreatic duct joining the duodenal wall was reviewed and divided into V, B-P and P-B type. The V type is the pancreatic duct and biliary duct joining the duodenal wall without a common channel; the B-P type is the biliary duct draining into the pancreatic duct and forming a common channel; and the P-B type is the pancreatic duct draining into the biliary duct and forming a common channel. APJ was measured on MRCP. The correlation between the APJ and the prevalence of acute pancreatitis was analyzed.
The APJ in group A was smaller than in group B (51.45°±13.51° vs. 65.76°±15.61°, P<0.05). According to the type of biliary duct and main pancreatic duct joining the duodenal wall, the prevalence of acute pancreatitis in the V type and in the B-P type was higher than in the P-B type (12/17 vs. 10/29, or 18/26 vs. 10/29, respectively, all P<0.05), whereas there were no significant difference for the prevalence of acute pancreatitis between the V type and B-P type (P>0.05). The APJ were 59.32°±20.04°, 60.22°±11.06°, 57.13°±17.27°, respectively in V type, B-P type and P-B type joining of main pancreatic duct (P>0.05).
A larger APJ is related to a higher prevalence of acute pancreatitis.
利用磁共振胰胆管造影（MRCP）研究胰胆管汇合角（APJ）与急性胰腺炎患病率之间的相关性。
2014年2月至2014年10月，选取32例胰腺正常的受试者（A组）和40例接受MRCP检查的急性胰腺炎患者（B组）纳入本研究。回顾胆管和主胰管连接十二指肠壁的类型，并分为V型、B-P型和P-B型。V型是胰管和胆管分别连接十二指肠壁，无共同通道；B-P型是胆管汇入胰管并形成共同通道；P-B型是胰管汇入胆管并形成共同通道。在MRCP上测量APJ。分析APJ与急性胰腺炎患病率之间的相关性。
A组的APJ小于B组（51.45°±13.51°对65.76°±15.61°，P<0.05）。根据胆管和主胰管连接十二指肠壁的类型，V型和B-P型急性胰腺炎的患病率高于P-B型（分别为12/17对10/29，或18/26对10/29，均P<0.05），而V型和B-P型之间急性胰腺炎的患病率无显著差异（P>0.05）。主胰管连接的V型、B-P型和P-B型中，APJ分别为59.32°±20.04°、60.22°±11.06°、57.13°±17.27°（P>0.05）。
较大的APJ与较高的急性胰腺炎患病率相关。
