Examiner questions:

1. What is your main differential diagnosis and why is this more likely than other differentials?

Answer: Acute cholangitis

  • Right upper quadrant pain with fever and jaundice (Charcot’s triad) is a constellation of symptoms associated with cholangitis
  • Clinically differs from cholecystitis with features of obstructive jaundice (yellow sclera, dark urine, itching, pale stools)
  • Acute pancreatitis classically presents with severe epigastric pain and vomiting, and could be a differential in a jaundiced patient, as gallstones are a common aetiology. But in this case, the presence of Charcot’s triad should point you towards cholangitis as the most likely differential
  • Less likely to be a malignancy due to the absence of red flag symptoms (weight loss, night sweats, abdominal mass) and acute rather than chronic/subacute onset of symptoms
2. State two blood results that are likely to be raised with this condition and why this is the case

Possible answer: ALPGGTbilirubin, any inflammatory markers (count as one point)

  • Rise in ALP, GGT and bilirubin is indicative of cholestasis or bile obstruction, a key factor in the pathophysiology of cholangitis
  • Rise in inflammatory markers is due to acute inflammation/infection 
3. Name three risk factors that a patient may have that can predispose them to this condition

Possible answers:

  • Aged over 50
  • Cholelithiasis
  • Strictures (benign or malignant)
  • Procedural injury to bile ducts
  • History of sclerosing cholangitis
4. Describe the management of this condition

Possible answer: 

  • Basic management: Sepsis six, including taking lactate, bloods and cultures, providing analgesia, IV fluids, antiemetics if required, strict fluid balance monitoring and consider catheterisation
  • Intravenous antibiotics in accordance with local guidelines
  • Endoscopic retrograde cholangiopancreatography within 24-48 hours to relieve the obstruction by extracting the stone, and thereby decompressing the biliary tree
  • Subsequent cholecystectomy in patients with cholangitis secondary to cholelithiasis (gallstones)
5. Mary is going to undergo an ERCP. Please briefly explain two complications of this procedure

Possible answer:

  • Perforation of bile duct, pancreatic duct or duodenum – this is a serious complication which can potentially require urgent surgical intervention and ITU input
  • Pancreatitis – traumatic manipulation and instrumentation of the biliary/pancreatic system can increase the risk of pancreatitis
  • Infection and bleeding – invasive procedures such as ERCP tend to carry risk of infection and bleeding
