胰腺结石的影像学诊断(附20例报告)

Imaging Diagnosis of Pancreatolith(Analysis of 20 Cases)

本文回顾分析了20例胰腺结石的临床、病理及影像学表现。检查方法包括:腹部X 线平片,US,ERCP,CT,上消化道钡餐检查,静脉肾盂造影,静脉或口服胆囊造影及术中胰管造影。按结石的大小分为大胰石和小胰石,按分布情况分为弥漫型、多部位型及局限型.作者认为胰石的大小及其分布与胰管梗阻有密切关系。并强调腹部平片对提高胰石检出率的重要性。

The clinical,pathological and ima-ging findings of pancreatolith wereanalyzed retrospectively.Examiningmethods included:X-ray abdominalfilms,US,ERCP,CT,barium mealof upper digestive tract,intravenouspyelography and oral cholecystogra-phy or intravenous cholangiography.The size of pancreatolith may be lar-ger(>0.5cm)or smaller(>0.5cm)and the distribution may be diffuse,multiple position and local.We sug-gest that the size of pancreatolith isrelated closely to obstructive degree ofpancreatic duct.The importance of ab-dominal plain films in increasing thediagnosis rate is emphasized.
