Surgery Shelf Prep!

Primary Sclerosing Cholangitis

Primary sclerosing cholangitis can look quiet at first, but it carries major shelf-level consequences. If you see a young man with cholestatic labs, pruritus, and ulcerative colitis, this is the diagnosis you need to catch. In this episode of Surgery Shelf Prep, we break down the classic presentation of primary sclerosing cholangitis, why Magnetic Resonance Cholangiopancreatography is the key test, and how to separate it from primary biliary cholangitis, autoimmune hepatitis, and other causes of jaundice. We also cover the highest-yield complications, including ascending cholangitis, cholangiocarcinoma, cirrhosis, fat-soluble vitamin deficiency, and the increased colon cancer risk seen with inflammatory bowel disease. This is a must-know hepatobiliary topic for the surgery shelf. Tune in and lock in the beads-on-a-string pattern, the ulcerative colitis association, and the management pathway from supportive care to liver transplant

Liver Abscess

Pyogenic liver abscess can look subtle at first, but on the shelf it is a big-time diagnosis. Fever, right upper quadrant pain, leukocytosis, and a rim-enhancing liver lesion should make you think fast. In this episode of Surgery Shelf Prep, we break down pyogenic liver abscess in a clear, high-yield way. You will learn the classic presentation, the major routes of infection to the liver, the most important organisms, how to separate pyogenic abscess from amebic liver abscess, and when management requires antibiotics alone versus percutaneous drainage. We also cover: How biliary disease, portal spread, and bacteremia lead to liver abscess Why diabetes is a major risk factor What imaging findings matter most The best antibiotic combinations to know for the shelf The key complications, including rupture, empyema, sepsis, and the colorectal cancer association Perfect for medical students preparing for the Surgery Shelf and anyone who wants a clean, organized review of this high-yield hepatobiliary topic. Hit play and lock in one of the most testable liver infections in surgery.

Liver Function Tests

Abnormal liver function tests can feel like a mess—until you learn the pattern. In this episode of Surgery Shelf Prep, we break down how to approach elevated liver labs the way the shelf wants: fast, organized, and high-yield. Chris and Mars walk through the three major liver injury patterns: cholestatic, hepatocellular, and mixed. You’ll learn how to use the lab pattern to narrow the differential, when to order a Right upper quadrant ultrasound first, how to spot dangerous causes like ascending cholangitis or acute liver failure, and how to avoid common traps like isolated bilirubin or isolated aspartate aminotransferase elevation. We cover: How to classify abnormal liver tests quickly When alkaline phosphatase points to obstruction Why gamma glutamyl transpeptidase helps confirm liver origin The meaning of the aspartate aminotransferase to alanine aminotransferase ratio When massive transaminase elevation suggests ischemia or drug toxicity How albumin and international normalized ratio reflect liver synthetic function Perfect for medical students who want a clean, testable framework for liver questions on the Surgery Shelf Exam. Listen in and learn how to turn confusing liver labs into easy shelf points.

Complications of Cirrhosis

Complications of cirrhosis can show up in a lot of different shelf-style ways, and this episode helps you organize them fast. In this high-yield review, Chris and Mars walk through the major complications every medical student needs to know: ascites, spontaneous bacterial peritonitis, esophageal varices, hepatic encephalopathy, hepatorenal syndrome, and hepatocellular carcinoma. They break down the classic presentations, the core pathophysiology, and the next-step management that shows up on exam questions, including paracentesis, ascitic neutrophil thresholds, octreotide, lactulose, rifaximin, TIPS, and liver cancer surveillance. Perfect for a quick but focused Surgery Shelf review.

Cirrhosis

Cirrhosis can look slow and chronic on the surface, but on shelf questions it shows up with big consequences fast. If you do not recognize the clues behind ascites, varices, encephalopathy, and spontaneous bacterial peritonitis, this topic can absolutely trip you up. In this episode of Surgery Shelf Prep, Chris and Mars break down cirrhosis in a clear, high-yield way for the surgery shelf exam. They walk through the classic presentation, the pathophysiology behind portal hypertension and liver failure, and the major complications you need to know cold, including ascites, esophageal varices, hepatic encephalopathy, and hepatorenal syndrome. You will learn how to approach diagnosis, when to perform paracentesis, how to interpret a high serum ascites albumin gradient, and why the spironolactone to furosemide ratio matters. They also cover screening for hepatocellular carcinoma, the role of lactulose, beta blockers, and T I P S, and when liver transplant becomes the definitive answer. Perfect for medical students who want a structured, test-focused review that makes cirrhosis feel manageable, logical, and high yield. Keep studying and get ready to lock this one in.
