Right upper quadrant pain in a surgical patient is three diagnoses wearing the same coat: acute cholecystitis, acute cholangitis and acute pancreatitis. Separating them is the whole station, because acute cholecystitis is usually a cholecystectomy decision, acute cholangitis is a drainage decision, and acute pancreatitis is a supportive care decision. According to NICE clinical guideline CG188, early laparoscopic cholecystectomy for acute cholecystitis should be carried out within one week of diagnosis.

Key takeaways

  • NICE CG188 offers early laparoscopic cholecystectomy, to be carried out within 1 week of diagnosis, to people with acute cholecystitis
  • The WSES 2020 guidelines on acute calculous cholecystitis recommend early laparoscopic cholecystectomy as soon as possible, within 7 days of hospital admission and within 10 days of symptom onset
  • Charcot's triad had a sensitivity of only 26.4% and a specificity of 95.9% for acute cholangitis in the Tokyo Guidelines multicentre analysis, so its absence does not exclude the diagnosis
  • The Tokyo Guidelines define Grade III cholangitis as cholangitis with new-onset dysfunction in at least one organ system, which is the grade that needs urgent biliary drainage
  • NICE NG104 says not to offer prophylactic antimicrobials in acute pancreatitis and not to make people nil by mouth without a clear reason
  • NG104 tells patients that approximately 15% to 20% of adults with severe acute pancreatitis die in hospital

How do I separate the causes of right upper quadrant pain?

Separate right upper quadrant pain by pattern: biliary colic is pain alone, acute cholecystitis is pain plus local and systemic inflammation, acute cholangitis is pain plus jaundice plus sepsis, and acute pancreatitis is pain radiating to the back with a raised amylase or lipase.

The Tokyo Guidelines diagnose acute cholecystitis on three parts: local signs of inflammation such as Murphy's sign or right upper quadrant mass, pain or tenderness; systemic signs such as fever, raised C-reactive protein or raised white cell count; and characteristic imaging findings.

For acute cholangitis the Tokyo Guidelines use systemic inflammation, cholestasis and imaging. Fever above 38 degrees Celsius or rigors, and a white cell count outside 4 to 10 times ten to the ninth per litre or a C-reactive protein of 1 mg/dL or more, make up part A.

Part B of the cholangitis criteria is a total bilirubin of 2 mg/dL or more, or alkaline phosphatase, gamma GT, AST or ALT above 1.5 times the upper limit of normal. Part C is biliary dilatation with evidence of an aetiology such as a stricture, stone or stent.

What is my immediate A to E management of right upper quadrant pain?

The immediate management of severe right upper quadrant pain is A to E with oxygen if hypoxic, intravenous access, fluid resuscitation, analgesia, blood cultures and antibiotics if septic, and a urinary catheter if the patient is shocked.

Treat the septic patient with right upper quadrant pain as sepsis first and a biliary diagnosis second. An obstructed, infected biliary tree will not respond to antibiotics alone, so the drainage conversation starts at the same time.

In acute pancreatitis, fluid resuscitation is the treatment. NICE NG104 directs you to the NICE guidance on intravenous fluid therapy in adults in hospital rather than printing a separate regimen.

Which investigations do I order in right upper quadrant pain?

In right upper quadrant pain, send a full blood count, C-reactive protein, urea and electrolytes, liver function tests, amylase or lipase, a venous gas with lactate, blood cultures if febrile, a coagulation screen and a group and save.

NICE CG188 offers liver function tests and ultrasound to people with suspected gallstone disease. The WSES 2020 guidelines likewise recommend abdominal ultrasound as the preferred initial imaging technique in acute calculous cholecystitis.

Ultrasound is imperfect in acute cholecystitis. The meta-analysis WSES cites gave summary sensitivity of 81% and specificity of 83%, so a negative scan in a convincing patient does not close the case.

For duct stones, NICE CG188 considers MRCP if ultrasound has not detected common bile duct stones but the duct is dilated or liver function tests are abnormal, and considers endoscopic ultrasound if MRCP does not allow a diagnosis.

How is acute cholecystitis managed?

Acute cholecystitis is managed with fluids, analgesia, antibiotics where indicated and early laparoscopic cholecystectomy, which NICE CG188 offers to be carried out within 1 week of diagnosis.

The WSES 2020 guidelines recommend laparoscopic cholecystectomy as the first-line treatment for acute calculous cholecystitis, performed as soon as possible, within 7 days from hospital admission and within 10 days from symptom onset.

WSES recommends avoiding laparoscopic cholecystectomy in septic shock or with absolute anaesthetic contraindications, and recommends subtotal cholecystectomy, open or laparoscopic, where anatomical identification is difficult and the risk of iatrogenic injury is high.

For the patient who is not fit for surgery, NICE CG188 offers percutaneous cholecystostomy to manage gallbladder empyema when surgery is contraindicated and conservative management has failed, and asks you to reconsider cholecystectomy once they are well enough.

How is acute cholangitis graded and drained?

Acute cholangitis is graded by organ dysfunction. The Tokyo Guidelines define Grade III, severe, as acute cholangitis associated with new-onset dysfunction in at least one organ or system, and that is the grade that needs urgent biliary drainage.

The organ dysfunctions listed are cardiovascular, needing dopamine at 5 micrograms per kilogram per minute or more or any dose of noradrenaline; neurological; respiratory, with a PaO2 to FiO2 ratio below 300; renal; hepatic, with an INR above 1.5; and haematological.

Grade II, moderate, acute cholangitis is defined by any two of an abnormal white cell count, a high fever of 39 degrees Celsius or more, age 75 years or over, a total bilirubin of 5 mg/dL or more, and hypoalbuminaemia. Grade I meets neither.

Say the treatment triad for acute cholangitis: antimicrobials, biliary drainage, and treatment of the underlying cause, usually by ERCP. The Tokyo Guidelines also ask for early drainage in patients who do not respond to initial medical treatment, whatever the grade.

How is acute pancreatitis assessed and managed?

Acute pancreatitis is diagnosed on sudden-onset abdominal pain with a raised blood lipase or amylase, and NICE NG104 notes that abdominal CT may confirm pancreatic inflammation if raised levels are not found.

NICE Clinical Knowledge Summaries classify severity as mild with no local or systemic complications or organ failure, moderately severe with local complications or transient organ failure resolving within 48 hours, and severe with persistent organ failure for more than 48 hours.

NICE NG104 gives four management points to quote: do not offer prophylactic antimicrobials; do not make people nil by mouth without a clear reason such as vomiting; offer enteral nutrition to anyone with severe or moderately severe disease, starting within 72 hours of presentation; and use parenteral nutrition only if enteral nutrition fails or is contraindicated.

NG104 also asks you not to assume acute pancreatitis is alcohol-related just because the person drinks, and to investigate metabolic causes, drugs, microlithiasis, hereditary causes, autoimmune pancreatitis, tumours and anatomical anomalies once gallstones and alcohol are excluded.

Who do I escalate right upper quadrant pain to, and when?

Escalate right upper quadrant pain to the surgical registrar on diagnosis, and escalate immediately when the patient is septic, jaundiced and shocked, because that combination is Grade III cholangitis until proved otherwise.

Involve gastroenterology or the ERCP service early for acute cholangitis, interventional radiology for the patient who needs a percutaneous cholecystostomy or a drain, and critical care for organ dysfunction.

For acute pancreatitis, NICE NG104 asks you to seek advice from a specialist pancreatic centre within the referral network if the patient develops necrotic, infective, haemorrhagic or systemic complications, and to discuss transfer.

NG104 also asks for an endoscopic approach to infected or suspected infected pancreatic necrosis where anatomically possible, and a percutaneous approach where it is not, balancing prompt debridement against the advantages of delay.

What is the interviewer listening for in a right upper quadrant pain scenario?

The interviewer in a right upper quadrant pain scenario is listening for a candidate who separates the three diagnoses out loud, resuscitates first, and knows which one is a drainage emergency.

  • Ultrasound and liver function tests named as the first investigations in suspected gallstone disease
  • Charcot's triad used as a prompt rather than a rule, with its poor sensitivity understood
  • Grade III cholangitis recognised as organ dysfunction requiring urgent drainage
  • Early laparoscopic cholecystectomy within one week of diagnosis quoted for acute cholecystitis
  • The NG104 pancreatitis rules on antibiotics, feeding and referral to a specialist pancreatic centre

What are the common mistakes in a right upper quadrant pain answer?

The commonest mistake in a right upper quadrant pain answer is relying on Charcot's triad, which had a sensitivity of only 26.4% for acute cholangitis in the Tokyo Guidelines multicentre analysis of 1,432 cases.

In that analysis, approximately 80%, or 59 of 72 Grade III cases, failed to satisfy Charcot's triad. A jaundiced septic patient without the full triad is still a cholangitis until the duct is imaged.

The second mistake is starving every patient with acute pancreatitis, which NICE NG104 specifically tells you not to do without a clear reason. The third is booking a delayed cholecystectomy when NICE CG188 wants it within one week.

How this comes up at the CST interview

Right upper quadrant pain usually arrives as a take referral with an ambiguous set of results: some tenderness, a mildly deranged liver screen and an amylase that is up but not diagnostic.

The panel then pushes on the separation. What would change your mind, what would you do if the bilirubin were 90, and who would you call at two in the morning for a shocked jaundiced patient.
