Cholecystitis and Ascending Cholangitis Flashcards
What is acute Cholecystitis?
Inflammation of the gallbladder, caused by blockage of the cystic duct preventing drainage
Acute cholecystitis is an important complication of what?
Gallstones
95% of cases of acute cholecystitis are caused by what?
gallstones (calculous cholecystitis)
Classical presentation of acute cholecystitis?
RUQ pain which pain radiate to the right shoulder
List 4 other presenting features of acute cholecystitis
Fever
Nausea and vomiting
Tachycardia and tachypnoea
RUQ tenderness
Murphy’s sign
Raised inflammatory markers and WBCs
How is Murphy’s sign performed?
What indicates a positive finding?
- Place a hand in RUQ and apply pressure
- Ask patient to take a deep breath in
- Gallbladder will move down during inspiration and come in contact with your hand
- Stimulation of inflamed gallbladder results in acute pain and sudden stopping of inspiration
Initial imaging for suspected acute cholecystitis?
Abdominal ultrasound scan
List 3 USS findings of acute cholecystitis
- Thickened gallbladder wall
- Stones or sludge in gallbladder
- Fluid around the gallbladder
How can we visualise the biliary tree in more detail if a CBD stone is suspected but not seen on an USS
(eg. bile duct dilatation or raised bilirubin)
Magnetic resonance cholangiopancreatography (MRCP)
Conservative management of acute cholecystitis?
- Nil by mouth
- IV fluids
- Antibiotics (cefuroxime)
- NG tube if required for vomiting
Definitive management for acute cholecystitis?
Laparoscopic cholecystectomy (within 1 week of presentation)
How may stones which are trapped in the CBD be removed?
ERCP
List 4 complications of acute cholecystitis
- Sepsis
- Gallbladder empyema
- Gangrenous gallbladder
- Perforation
What is Gallbladder Empyema?
Infected tissue and pus collecting in the gallbladder
Management of Gallbladder empyema?
IV antibiotics and one of two main options:
- Cholecystectomy
- Cholecystostomy (drain insertion)
Typically history of chronic cholecystitis?
Recurrent or untreated cholecystitis, which has led to a persistent inflammation of the gallbladder wall
Presentation of chronic cholecystitis?
Ongoing RUQ or epigastric pain with associated nausea and vomiting
Management of chronic cholecystitis?
Elective cholecystectomy
What is ascending cholangitis?
Infection and inflammation in the bile ducts
Surgical emergency as it has a high mortality due to sepsis and septicaemia
List the 2 main causes of ascending cholangitis
- Obstruction in the bile ducts eg. Gallstones in the CBD
- ERCP (Infection introduced)
List the 3 most common organisms in ascending cholangitis
- Escherichia coli
- Klebsiella species
- Enterococcus species
What is Charcots Triad
- RUQ pain
- Fever
- Jaundice
Acute management of ascending cholangitis
- Nil by mouth
- IV fluids
- Blood cultures
- IV antibiotics
- ERCP after 24-48 hours to relieve any obstruction
First line investigation for suspected ascending cholangitis
Endoscopic Ultrasound
