Abstract
Background: Patient presented with jaundice, initial evaluation should be ultrasonography for evaluation of liver parenchymal changes, cirrhosis and assessment of hepatic vascularity and evaluation of intrahepatic, extrahepatic biliary system. Aim of the Work: to compare between the Conventional US and Endoscopic Ultrasound in diagnosis of obstructive jaundice and other diagnostic modality including CT /MRI, ERCP for diagnosis and evaluation of the cause of OJ. Patients and Methods: This study was conducted on 60 patients with obstructed jaundice as evident by ultrasonography in the form of dilated CBD with IHBRDs, with visualization of Gall bladder content and pancreas if can be well visualized, all patients had clinically apparent jaundice with disturbance of liver biochemical profile, all patient underwent EUS and compare finding with US including CBD diameter and IHBRDs degree. Results: US provide better visualization of CBD and IHBRDs with diagnosis of pathological lesion including stones, malignancy. EUS also has better visualization of pancreatic pathology including inflammation and malignancy and extent of the tumor including local extent, lymphatic spread with vascular invasion. Conclusion: EUS is better than US and other modality CT&MRI and ERCP in diagnosis of distal CBD stricture including malignant obstruction especially in cases of early malignancy and small tumors , and calculary distal obstruction. CT is insensitive in diagnosis of periampullary cancer, EUS provide early diagnosis of Pancreaticobiliary malignancy and give better advandage for early
resectability .
