Summary
Cholestasis, a condition of abnormal bile excretion, is diagnosed using bedside liver ultrasonography. Management strategies for cholestasis depend on whether the obstruction is intrahepatic or extrahepatic, guiding further diagnostic and therapeutic interventions.
Area of Science:
- Hepatology
- Gastroenterology
- Diagnostic Imaging
Context:
- Cholestasis involves impaired bile excretion from hepatocytes to the ampulla of Vater.
- Accurate diagnosis is crucial for effective patient management.
- Bedside liver ultrasonography is a key initial diagnostic tool.
Purpose:
- To outline the diagnostic and management pathways for cholestasis.
- To differentiate between intrahepatic and extrahepatic cholestasis.
- To highlight the roles of various medical specialists and imaging modalities.
Summary:
- Diagnosis begins with liver ultrasonography to identify bile duct dilatation.
- Intrahepatic cholestasis management involves blood tests and potential liver biopsy.
- Extrahepatic cholestasis requires a multidisciplinary approach utilizing MRCP, EUS, and ERCP.
Impact:
- Provides a clear framework for diagnosing and managing cholestasis.
- Emphasizes the importance of a multidisciplinary team in complex cases.
- Facilitates timely and appropriate interventions for patients with cholestasis.

01:26Endoscopic Procedures V: ERCP
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
