• W2911447658 abstract "Purpose: ERCP remains the gold standard for diagnosis and initial treatment of patients with obstructive jaundice. Accuracy of ultrasound in such patients and its concordance with ERCP has not been studied in our part of the world. Objective: To compare the efficacy of abdominal ultrasound and ERCP in determining the etiology of obstructive jaundice Methods: Study was carried out at a tertiary care referral center in Lahore, Pakistan from August 2006 to May 2007. Patients undergoing ERCP for provisional diagnosis of obstructive jaundice were included. Abdominal ultrasonographic examination was conducted before ERCP and all patients underwent ERCP under conscious sedation. Diagnosis on ultrasound and ERCP was compared using cross tabulation. Results: A total of 54 patients (male: female ratio of 0.6 (22/32)) with a mean age of 47.22 (±14.94) were included in the study. Jaundice and Abdominal pain were the predominant presenting symptoms in 48 (88.9%) and 42 (77.8%) patients respectively whereas pruritis and fever were present in 27 (50%) and 11 (20.4%) patients respectively. Choledocholithiasis/sludge was accurately diagnosed in 8 out of nine patients. Ultrasound only diagnosed 50% of the patients with Peri-ampullary tumors and pancreatic carcinoma accurately; sonographic finding of a distal CBD stricture without any definitive diagnoses were noted in the rest of the patients. Ultrasound was very accurate in determining the etiology of various proximal CBD lesions. In the 4 patients with mid-CBD strictures on ultraosound, 2 were found to have gall bladder carcinoma, 1 common hepatic duct stricture and 1 acute pancreatitis- diagnoses which are not usually possible on ERCP. Of the 3 patients with Cholangiocarcinoma, 2 cases had been suspected to have this diagnosis on ERCP and ultrasound alike while the third one had a mid-CBD stricture on ultrasound. Ultrasound findings had complete concordance with the ERCP diagnoses in cases of post-cholecystectomy strictures, fistulas and CBD ligation. Conclusion: Ultrasound was very accurate in determining the etiology of various proximal CBD lesions. The accuracy of Ultrasound in determining the etiology of distal biliary obstructive processes is significantly lower but is useful as inital investigation. Abdominal ultrasound and ERCP are complementary investigations in patients with obstructive jaundice." @default.
