胰管的形态可因胚胎发生中的改变而有变异,这些变异可能引起明显的临床症状。为了更准确地解释内窥镜下胰管造影及其临床意义,熟悉这些异常是必要的。本文在复习胰管的胚胎发生,叙述胰管造影正常形态后,列举了胰管造影的若干变异,并提出一项以胚胎学为基础的分类法。移动异常:十二指肠旋转时若腹胰不能移动,即造 Pancreatic duct morphologies can vary due to changes in embryogenesis, and these mutations can cause overt clinical symptoms. In order to more accurately explain the endoscopic pancreatography and its clinical significance, familiarity with these abnormalities is necessary. After reviewing the pancreatic duct embryogenesis and describing the normal morphology of pancreatic duct angiography, we enumerated several variations of pancreatography and proposed a classification based on embryology. Abnormal movement: duodenal rotation if the abdominal pancreas can not move, that is made
