胰腺分裂的影像诊断

报道３例经影像学及手术证实的ＰＤ。分析了ＰＤ的影像表现．ＰＤ以ＥＲＣＰ诊断最佳，可分典型ＰＤ（腹、背胰管完全分离，２例），不典型ＰＤ（腹、背胰管之间有交通，１例），其共同点是以背胰管经副乳头引流为主．强调腹、背胰管同时插管造影是诊断ＰＤ的关键。Ｂ超及常规ＣＴ对ＰＤ的诊断价值不大。

Imaging Diagnosis of Pancreas Divisum

Three cases of pancreas divisum (PD) verified by imaging and operation were reported.After analysis of the imaging manifestations,we reached that PD was best diagnosed by endoscopic retrograde cholangio pancreatography(ERCP). PD was classified into: 1. Typical PD (complete divisum of ventral and dorsal ducts, two cases); 2. untypical PD (presenting a channel between both ducts, one case).The common feature of PD was that it was drainaged by doral pancreatic duct through minor papilla. It is emphasized that the key for the diagnosis of PD was by pancreatography through minor and major papilla cannulation during the same examination. B- type ultrasound and routine computed tomography is of little value for the diagnosis of PD.
