Abstract:
Objective To investigate the diagnostic values of imaging techniques and endoscopy in detection the causes of post-hepatic obstructive jaundice.Methods The clinical data of 57 patients with post-hepatic obstructive jaundice were retrospectively studied.The causes of the obstruction and the findings of uhrasonography(US),computerized tomography(CT),magnetic resonance imaging(MRI)or MRIcholangiopancreatography(MRCP),endoscopic retrograde cholangiopancreatography(ERCP)and endoscopic ultrasonography(EUS)were compared.Results The causes of 57 patients with post-hepatic obstruetive jaundice were benign obstruction in 42(including stones in common bile duct in 38,ascariasis of CBD in 1,postoperative stricture in 2 and chronic pancreatitis in 1),and malignant lesions in 15(including pancreatic head carcinoma in 11 and ampullary carcinoma in 4).The diagnostic accuracy in terms of lesion location of US,CT,MRI+MRCP,ERCP and EUS were 71.93%(41/57),88.00%(22/25),94.59% (35/37),100.00%(47/47)and 96.77%(30/31),respectively;the diagnostic accuracy of cause of obstruction were 63.16%(36/57),80.00%(20/25),83.78%(31/37),100%(47/47)and 96.77% (30/31),respectively.Conclusion Benign diseases are the main causes of post-hepatic obstructive jaundice,but malignant ones are not rare.It is important to combine miscellaneous imaging techniques and endoscopy in diagnosis.
