Study Notes
Gallstones and Biliary System Conditions
- Gallstones are crystalline structures, primarily formed from cholesterol, bile pigments, and phospholipids. They form in the gallbladder or biliary tree.
- Cholesterol stones are the most common type in Western populations, appearing yellowish.
- Pigment stones are usually black or brown, forming from bilirubin.
- Mixed stones combine cholesterol and pigment elements.
- Gallstones can cause biliary colic (sudden RUQ pain).
- Acute cholecystitis is gallbladder inflammation from persistent gallstone obstruction. A Murphy's sign (inspiratory arrest during palpation) is a key symptom.
- Ascending cholangitis is a biliary tree infection, often from bacterial invasion after ductal obstruction.
- Charcot's triad includes RUQ pain, fever, and jaundice, indicative of acute cholangitis.
- Jaundice is yellowing of skin, sclera, and mucous membranes; it results from elevated bloodstream bilirubin.
- Pre-hepatic jaundice is due to increased hemolysis, elevating unconjugated bilirubin.
- Hepatic jaundice has mixed hyperbilirubinemia due to impaired hepatocyte conjugation.
- Post-hepatic jaundice is from biliary obstruction, increasing conjugated bilirubin.
Pathophysiology of Gallstone Formation
- Gallstone formation results from imbalances of bile components, leading to insoluble crystals forming into stones in the gallbladder obstructing the cystic or common bile duct..
- Cholesterol supersaturation in bile leads to nucleation of cholesterol monohydrate crystals.
- Lithogenic bile, the bile containing components encouraging stone formation.
Clinical Applications and Diagnosics
- Case studies and diagnostic approaches are discussed including ultrasound (US), Liver Function Tests (LFTs). CT/MRI, to detect gallstones, inflammation, and ductal dilations.
- Treatment options include pain management (NSAIDs), antibiotic therapy (ascending cholangitis), and cholecystectomy (surgery to remove the gallbladder) for cholecystitis and other conditions.
- Acute pancreatitis (inflammation of the pancreas). often is caused by gallstones or alcohol.
Pharmacology and Differential Diagnoses
- Pain management (e.g. NSAIDs, opioids) for biliary colic and/or cholecystitis.
- Antibiotics for ascending cholangitis (broad-spectrum, IV).
- Liver function tests (LFTs) evaluate bilirubin levels (conjugated vs. unconjugated) and enzyme levels (ALT/AST/ALP) to diagnose liver and biliary function.
- Differential diagnoses for biliary colic, cholecystitis, ascending cholangitis.
Imaging and Investigations
- Ultrasound (US) is commonly used to diagnose gallstones, ductal dilatation, and cholecystitis.
- Liver function tests help identify jaundice types (pre, hep, post) by analyzing bilirubin levels.
- ALT/AST help determine the extent of liver damage (acute or chronic).
- ALP elevates in post-hepatic jaundice from biliary obstruction/cholestasis.
Summary
- Gallstones result from imbalances in bile components and can lead to several complications.
- Jaundice may arise from pre-hepatic, hepatic, or post-hepatic causes.
- Appropriate diagnostic procedures (imaging, liver function tests) are key to identifying and treating gallstone-related conditions.
