Acute Cholangitis, Alc Hep, Anal Fissure, Appendicitis, Autoimmune hep, Barret's Flashcards
What is Charcot’s Triad?
Fever, Jaundice, RUQ pain
What are the most common causes?
Choledocholithiasis (stones in the biliary tree) and benign + malignant strictures
What are some diagnostic factors?
RUQ pain/tenderness
Jaundice
Pruritus
Pale stools
Hypotension
Mental status changes
What are risk factors for AC?
Age >50
Cholelithiasis
Strictures
What are 1st investigations for AC?
Serum urea, creatinine, ABG (acidosis suspecting sepsis), FBC
Consider abdominal CT with IV contrast/MRCP/Percutanrous transhepatic cholangiography
What is treatment for AC?
- IV antibiotics + intensive medical management
- Biliary decompression via ERCP if patient is worsening
PTC if poor candidate for ERCP (e.g., status post-Roux-en-Y gastric bypass, presence of oesophageal stricture) - Biliary decompression surgically with laparoscopic choledochotomy with T-tube placement or cholecystectomy with common bile duct exploration
What drug is used as an alcohol detox in hospital?
Chlordiazepoxide to help withdrawal (generously first 3 days and then wean off over a week)
What drugs can be used to prevent alcohol relapse?
Acamprosate and metronidazole - cause acetaldehyde buildup so any alcohol ingestion will cause unpleasant side effects like headaches, flushing, palpitations.
What are the CAGE questions?
C: Ever felt like cutting down on drinking?
A: Have people annoyed you by criticising your drinking?
G: Have you ever felt guilty about your drinking?
E: Ever had an eye-opener in the morning?
How would a patient with alcoholic hepatitis present?
With malaise, increased TPR, AST:ALT>2, tender hepatomegaly and jaundice, low WBC and platelets due to toxicity/hypersplenism
How is alcoholic hepatitis treated?
- If ascites, ascitic tap, screen for infection and SBP
- Stop alcohol
- Maddrey discriminant factor takes patient’s PT and bilirubin into account - if over 31 and encephalopthy present, give prednisolone
- Vitamin K and thiamine
What indicates anal fissure?
Fresh red blood on wiping
Tearing sensation on passing stool
Sentinel pile present
Visible fissure
How are anal fissures treated?
Glyceryl trinitrate topically or diltiazem
If resistant/chronic:
Botulinum toxin A
Surgical sphincterectomy/anal advancement flap
How does appendicitis usually present?
Acute abdominal pain starting in the mid-abdomen and later localising to the right lower quadrant. Associated with fever, anorexia, nausea, vomiting, and elevation of the neutrophil count.
What is appendicitis usually caused by?
Obstruction of the lumen of the appendix (by faecolith, normal stool, infective agents, or lymphoid hyperplasia)
How is uncomplicated appendicitis in adults managed?
Supportive treatment: Keep patient nil by mouth with maintenance fluids if surgery being considered + paracetamol/morphine sulfate
Prophylactic antibiotics with laparoscopic appendicectomy within 24 hours
What are potential complications of appendicitis?
Perforation, acutely unwell, abscess/phlegmon
What are symptoms of autoimmune hepatitis?
Fever, malaise, urticarial rash, polyarthritis, glomerulonephritis
What are risk factors of autoimmune hepatitis?
Female sex, Genetic predisposition, immune dysregulation
What would tests indicate in autoimmune hepatitis?
Elevated LFTs, hypergammaglobulinaemia, positive autoantibodies, liver biopsy shows mononuclear infiltrates of portal and periportal areas
MRCP helps exclude PSC if ALP disproportionately elevated
What are the 2 types of autoimmune hepatitis?
Type 1: ASMA (anti smooth muscle antibody) + ANA (antinuclear antibody) positive with good response to immunosuppression and presenting with cirrhosis
Type 2: LKM1 antibody positive (anti-liver/kidney microsomal type 1) with ASMA and ANA negative - more common in children and worse prognosis
What is the definition of severe AIH and how is it treated?
Acute severe AIH as patients presenting with jaundice, international normalised ratio >1.5 to <2, no encephalopathy, and no previously recognised liver disease.
60mg prednisolone OD and taper as per response
