The study was conducted to evaluate the frequencies of the anatomic variations and the gender distributions of these variations of the pancreatic duct and their relevance with the Cambridge classification system as morphological sign of chronic pancreatitis using magnetic resonance cholangiopancreatography (MRCP).
We retrospectively reviewed 1312 consecutive patients who referred to our department for MRCP between January 2013 and August 2015. We excluded 154 patients from the study because of less than optimal results due to imaging limitations or a history of surgery on pancreas. Finally a total of 1158 patients were included in the study.
Among the 1158 patients included in the study, 54 (4.6%) patients showed , 13 patients (1.2%) were defined as . When we evaluated the course of the pancreatic duct, we found the prevalence 62.5% for descending, 30% for sigmoid, 5.5% for vertical and 2% for loop. The most commonly observed pancreatic duct configuration was Type 3 in 528 patients (45.6%) where 521 patients (45%) had Type 1 configuration.
Vertical course (p = 0.004) and Type 2 (p = 0.03) configuration of pancreatic duct were more frequent in females than males. There were no statistically significant differences between the gender for the other pancreatic duct variations such as and course types other than vertical course (p > 0.05 for all). Variants of and normal pancreatic duct variants were not associated with morphologic findings of chronic pancreatitis by using the Cambridge classification system. The is a rare type of anatomical variation of the pancreatic duct, which might be considered as a predisposing factor to the onset of idiopathic pancreatitis.
本研究旨在通过磁共振胰胆管造影（MRCP）评估胰腺导管解剖变异的频率、这些变异的性别分布及其与作为慢性胰腺炎形态学标志的剑桥分类系统的相关性。
我们回顾性分析了2013年1月至2015年8月间连续转诊至我科进行MRCP检查的1312例患者。由于成像限制导致结果不理想或有胰腺手术史，我们将154例患者排除在研究之外。最终，共有1158例患者纳入研究。
在纳入研究的1158例患者中，54例（4.6%）患者表现为 ，13例（1.2%）患者被定义为 。当我们评估胰腺导管的走行时，发现下降型占62.5%，乙状结肠型占30%，垂直型占5.5%，袢型占2%。最常见的胰腺导管形态为3型，共528例患者（45.6%），其中521例患者（45%）为1型形态。
胰腺导管的垂直走行（p = 0.004）和2型（p = 0.03）形态在女性中比男性更常见。对于其他胰腺导管变异，如 以及除垂直走行外的其他走行类型，性别之间无统计学显著差异（所有p>0.05）。使用剑桥分类系统时， 变异和正常胰腺导管变异与慢性胰腺炎的形态学表现无关。 是一种罕见的胰腺导管解剖变异类型，可能被视为特发性胰腺炎发病的易感因素。
