【摘要】：目的:探讨主胰管胰头段水平角及开角方向与急性胰腺炎的相关性。方法:回顾性连续搜集临床及上腹部MRI检查诊断为急性胰腺炎的213例患者的临床资料,按纳入和排除标准入选60例(其中男38例,女22例,平均年龄45岁)为观察组,同期收集43例正常胰腺(男22例,女21例,平均年龄53岁)为对照组。两组均行MRCP,数据上传至工作站行图像处理,在主胰管显示清晰完整的层面上连续三次测量主胰管胰头段及主胰管头尾两端连线与水平线的夹角,记录平均数值及主胰管胰头段水平角方向并行统计学分析。结果:急性胰腺炎组,主胰管胰头段及主胰管头尾两端连线与水平线的夹角分别为25.64°±20.32°和28.07°±11.11°,而正常胰腺组为30.56°±18.56°和28.65°±10.49°(t=1.254/0.253,P=0.213/0.801)。60例急性胰腺炎组中,主胰管胰头段开角向上36例,主胰管胰头段与水平线的夹角为32.19°±23.19°,向下24例,其夹角为16.08°±8.80°;43例正常胰腺组,开角方向上37例,主胰管胰头段与水平线的夹角为32.77°±18.91°,向下6例,其夹角为16.94°±7.66°。急性胰腺炎组与正常胰腺组,向上或向下开角方向,主胰管胰头段与水平线的夹角差异均无统计学意义(t=0.117/0.219,P=0.907/0.828),而主胰管胰头段与水平线的开角方向差异具有统计学意义(χ2=8.232,P=0.004)。全部病例中向上开角的角度(32.48°±20.98°)与向下开角的角度(16.26°±8.46°)间差异有统计学意义(t=4.901,P=0.000)。结论:急性胰腺炎与主胰管胰头段水平角大小无关,但与水平角的开角方向密切有关,临床急性胰腺炎多以开角向下方向为主。
[Abstract]:Objective: to investigate the correlation between the horizontal and open angle of the pancreatic head segment of the main pancreatic duct and acute pancreatitis. Methods: the clinical data of 213 patients with acute pancreatitis diagnosed by clinical and epigastric MRI were collected retrospectively. According to the criteria of inclusion and exclusion, 60 cases (38 males and 22 females, mean age 45 years) were selected as the observation group. 43 cases of normal pancreas (22 males and 21 females, mean age 53 years) were collected as control group. The MRCP, data of both groups were uploaded to the workstation for image processing. The angles between the head of the main pancreatic duct and the ends of the head and tail of the main pancreatic duct and the horizontal line were measured three times on the clear and complete layer of the main pancreatic duct. The mean value and the horizontal angle of the pancreatic head of the main pancreatic duct were recorded and analyzed statistically. Results: in the acute pancreatitis group, the angles between the head of the main pancreatic duct and the ends of the head and tail of the main pancreatic duct were 25.64 掳卤20.32 掳and 28.07 掳卤11.11 掳, respectively, compared with 30.56 掳卤18.56 掳and 28.65 掳卤10.49 掳in the normal pancreas group. The angle between the head of the main pancreatic duct and the horizontal line was 32.19 掳卤23.19 掳, and the angle was 16.08 掳卤8.80 掳in 43 cases of normal pancreas. The angle between the head of the main pancreatic duct and the horizontal line was 32.77 掳卤18.91 掳and 16.94 掳卤7.66 掳in 43 cases of normal pancreas group, and the angle between the head of the main pancreatic duct and the horizontal line was 32.77 掳卤18.91 掳, and the angle of the angle was 16.94 掳卤7.66 掳. There was no significant difference between the acute pancreatitis group and the normal pancreas group in the angle of opening up or down, the angle between the head of the main pancreatic duct and the horizontal line (t = 0.117 / 0.219g / 0.9070.828), but there was a significant difference in the opening angle between the head of the main pancreatic duct and the horizontal line (蠂 28.232P0. 004). There was significant difference between the angle of upward opening (32.48 掳卤20.98 掳) and the angle of downward angle (16.26 掳卤8.46 掳) in all cases (t = 4.901). Conclusion: acute pancreatitis is not related to the horizontal angle of the pancreatic head segment of the main pancreatic duct, but is closely related to the opening angle direction of the horizontal angle.
