Summary
Brief summary (as posted)
Endoscopic retrograde cholangiopancreatography and endoscopic ultrasound are increasingly being used to manage complex disease of the bile duct, pancreas and cancer. Gastroenterology patients at the Los Angeles County Hospital presents a unique and diverse patient population. Our aim is to study the biochemical, radiographic, and clinical predictors of bile duct stones. Exploratory aims include the study of the management of cholangitis, bile leaks, GI cancer diagnosis and management, and the management of pancreaticobiliary problems in the underserved. All patients managed by EUS or ERCP at the LA County \& USC University Hospitals will be enrolled in the databaseThe timing, clinical presentation, and objective details of patient presentation are recorded prospectively. Additionally the results of the subsequent ERCP and EUS procedures. Subsequent, clinical course and pathology will also be recorded.
