Study Notes
Gallbladder Disorders
- Cholelithiasis (Gallstones): Formation of gallstones in the gallbladder. These can be cholesterol or pigment stones.
-
Risk Factors:
- "5 F's": Fat, Fertile, Forty, Female, Flatulent
- Obesity
- Rapid weight loss
- Pregnancy
- Crohn's disease
- Medications (e.g., octreotide, ceftriaxone).
- Prevention: Low-carb diet, physical activity, high-fiber diet, NSAIDs, caffeinated coffee in females.
- Symptoms: Often asymptomatic, but can cause episodic right upper quadrant (RUQ) pain (biliary colic).
- Diagnosis: Ultrasound (US) is the gold standard for gallstones.
-
Treatment:
- Asymptomatic: No treatment needed, observation.
- Symptomatic: Laparoscopic cholecystectomy.
- Nonsurgical candidates: Ursodeoxycholic acid (bile acid therapy).
- Ursodeoxycholic Acid (MOA): Reduces cholesterol saturation in bile, dissolving cholesterol stones.
- Indications: Non-surgical candidates, or to prevent stones in those experiencing rapid weight loss.
- Side Effects: Diarrhea, pruritus (itching).
- Clinical Pearls: Most effective for small, non-calcified cholesterol stones.
Cholecystitis
- Definition: Inflammation of the gallbladder, often caused by gallstones.
-
Clinical Features:
- Persistent right upper quadrant (RUQ) pain
- Fever
- Vomiting
- Murphy's sign
- Jaundice (in some cases)
-
Diagnosis:
- Ultrasound: Thickening of gallbladder wall (> 5 mm), pericholecystic fluid, Murphy's sign.
- HIDA scan: Confirms cystic duct blockage.
-
Treatment:
- NPO (Nothing by mouth), IV fluids, analgesics, broad-spectrum antibiotics (3rd-generation cephalosporins + metronidazole)
- Antibiotics: Cover gram-negative and anaerobic bacteria; ceftriaxone + metronidazole is an option.
- Surgery: Laparoscopic cholecystectomy is the treatment of choice.
Choledocholithiasis
- Definition: Gallstones in the common bile duct (CBD).
-
Clinical Features:
- Right upper quadrant (RUQ) pain
- Fever
- Jaundice (Charcot's triad)
- Altered mental status and hypotension (Reynolds' pentad): suspect acute suppurative cholangitis
-
Diagnosis:
- Labs: Elevated AST, ALT, ALP, bilirubin.
- Imaging: Ultrasound (US), Endoscopic retrograde cholangiopancreatography (ERCP). ERCP is the gold standard for diagnosis and treatment.
-
Treatment:
- ERCP for stone removal and stent placement.
- Antibiotics: Fluoroquinolone, ampicillin, gentamicin + metronidazole.
- Cholecystectomy.
Antibiotics
- Rationale: Control secondary infections and prevent serious complications in choledocholithiasis and cholecystitis. These conditions often involve biliary obstruction, which can lead to bacterial colonization and infection.
- Bacteria: Common culprits include Escherichia coli, Klebsiella species, and Bacteroides fragilis.
- Specific antibiotics are chosen based on their effectiveness against various bacterial types.
- General considerations: Monitoring liver function and kidney function are important when choosing antibiotics. Adjust dosages if needed.
Other GI Infections
- Diverticulitis: Inflammation of the diverticula in the colon, often due to bacterial infection. E. coli, Bacteroides fragilis are common. Treatment: outpatients typically receive ciprofloxacin + metronidazole (or vancomycin + metronidazole for severe cases).
- Infectious Diarrhea: Shigella, Salmonella, Campylobacter, and certain E. coli strains are potential causes.
- Clostridium difficile Infection (CDI): Overgrowth of Clostridium difficile due to antibiotic use can cause diarrhea, pseudomembranous colitis, and other related complications.
- Spontaneous Bacterial Peritonitis (SBP): Infection of ascitic fluid (fluid around the liver). Gram-negative bacteria like E. coli, Klebsiella are common culprits. Treatment usually involves broad-spectrum antibiotics.
Liver Disorders
- Alcoholic Liver Disease/Severe Alcoholic Hepatitis: Alcohol consumption leads to direct liver damage, inflammation, and potential progression to liver failure. Treatment may include abstinence, medications to reduce cravings, and supportive care.
Viral Hepatitis
- Hepatitis A: Fecal-oral transmission. Symptoms may include fever, nausea, and jaundice. Treatment is generally supportive.
- Hepatitis B: Bloodborne transmission. Infection can be acute or chronic. Treatment includes antiviral therapy.
- Hepatitis C: Bloodborne transmission. Infection often leads to chronic disease unless treated with direct-acting antivirals.
Cirrhosis
- Definition: Irreversible liver fibrosis and nodular regeneration.
- Symptoms: Early: Fatigue, weight loss, nausea; Late: Ascites, encephalopathy, spider nevi, palmar erythema.
- Treatment: Manage complications (e.g., ascites, encephalopathy) and address underlying cause. Liver transplantation may be indicated in severe cases.
Acute Pancreatitis
- Definition: Inflammation of the pancreas.
- Causes: Gallstones, alcohol abuse, hyperlipidemia and certain medications frequently implicated
- Symptoms: Severe epigastric pain radiation to back, nausea, and vomiting.
- Diagnosis: Elevated amylase and lipase levels in the blood and imaging studies (i.e., ultrasonography or CT scans).
- Treatment: supportive care, intravenous fluids, and pain management. Antibiotics are reserved for infected necrosis.
Chronic Pancreatitis
- Definition: Chronic inflammation causes irreversible pancreatic damage.
- Symptoms: Chronic abdominal pain, malabsorption, steatorrhea, and diabetes are common symptoms.
- Treatment: Address underlying causes, manage pain, and provide pancreatic enzyme replacement for improved digestion and nutrition.
