Biliary disease

Colic, cholecystitis or cholangitis — the treatment is very different. Separate simple biliary colic from inflamed gallbladder (cholecystitis) and infected bile duct (cholangitis). Cholangitis is the killer: it needs antibiotics and drainage. Built for revision, not live patient decisions.

🩺
Pearl

Charcot's triad (fever, jaundice, RUQ pain) is present in only about half of cholangitis cases. Any patient with gallstones who has a fever and deranged LFTs should be treated as cholangitis until proven otherwise.

First actions

  • 💊Analgesia + antiemetic
  • 🩸Bloods
  • USSAbdominal ultrasound
  • ℞Antibiotics if infected
  • IVFluids if septic
  • ☎Surgical / GI team

Understand the patient

the biliary spectrum

The spectrum

  • Biliary colic — RUQ/epigastric pain, often after fatty food, settles within hours; no fever, normal bloods
  • Acute cholecystitis — persistent pain, fever, Murphy's sign, raised WCC/CRP; USS: thick wall, pericholecystic fluid, stones
  • Choledocholithiasis — stone in the CBD: jaundice, obstructive LFTs, dilated duct
  • Cholangitis — infection behind an obstructed duct: fever, jaundice, RUQ pain (Charcot's); add shock and confusion (Reynolds' pentad)
  • Gallstone pancreatitis — see the pancreatitis page

Treatment (NICE CG188, Tokyo guidelines)

  • Cholecystitis — antibiotics, analgesia; laparoscopic cholecystectomy within 1 week of diagnosis (NICE); percutaneous cholecystostomy if unfit
  • Cholangitis — antibiotics + biliary drainage (ERCP); urgency by severity: severe/organ dysfunction → urgent; moderate → early (within 24–48 h)
  • CBD stones — ERCP or surgical bile duct clearance with cholecystectomy
  • Biliary colic — analgesia, elective cholecystectomy

Investigate — what to order, when, and what it tells you

test with a question in mind

Bloods

LFTs
Obstructive pattern (raised ALP, GGT, bilirubin) suggests CBD stone.
Others
FBC, CRP, lipase, U&E, clotting, cultures.

USS

First-line
Stones, wall thickening, pericholecystic fluid, CBD diameter.

MRCP

When
Suspected CBD stones with non-diagnostic USS.

ECG

Always
Upper abdominal pain can be inferior MI.

How the plan comes together

disposition · handover

home

Biliary colic, pain settled, normal bloods: analgesia, low-fat diet advice, surgical outpatient referral for cholecystectomy.

admit / ERCP

Cholecystitis, CBD stones, cholangitis, pancreatitis.

Hand over: diagnosis, LFT trend, USS findings, antibiotic, ERCP/cholecystectomy plan.

🩺
Pearl

Colic settles, cholecystitis needs antibiotics and early surgery, and cholangitis needs antibiotics plus drainage, urgently. Fever and deranged LFTs mean cholangitis until proven otherwise. Nicely done getting here.

Q

Frequently asked questions

quick answers
What are the red flags for gallstone disease (biliary colic, cholecystitis, cholangitis)?
  • Fever + jaundice + RUQ pain — think ascending cholangitis
  • Hypotension, confusion + Charcot's triad — think severe cholangitis (Reynolds' pentad)
  • Persistent RUQ pain, fever, Murphy's positive — think acute cholecystitis
  • Jaundice, dilated CBD — think choledocholithiasis
  • Epigastric pain, raised lipase — think gallstone pancreatitis
  • Older patient with obstruction + air in biliary tree — think gallstone ileus
What is the initial management of gallstone disease (biliary colic, cholecystitis, cholangitis)?
  • Analgesia + antiemetic — —
  • Bloods — FBC, CRP, LFT, lipase/amylase, U&E, clotting, cultures if febrile
  • Abdominal ultrasound — stones, gallbladder wall, CBD diameter
  • Antibiotics if infected — cholecystitis/cholangitis — per local policy
  • Fluids if septic — sepsis bundle
  • Surgical / GI team — ERCP if cholangitis

Always alongside senior support and your local guideline.

What diagnoses must you not miss in gallstone disease (biliary colic, cholecystitis, cholangitis)?
  • Ascending cholangitis — fever + jaundice
  • Gangrenous / perforated gallbladder — worsening cholecystitis
  • Gallstone pancreatitis — lipase raised
  • Inferior MI / pneumonia (mimics) — upper abdominal pain

Open each one in the must-not-miss section for what points toward it, how to rule it in, and how to manage it.

What investigations should a junior doctor order for gallstone disease (biliary colic, cholecystitis, cholangitis)?
  • Bloods — Obstructive pattern (raised ALP, GGT, bilirubin) suggests CBD stone.
  • USS — Stones, wall thickening, pericholecystic fluid, CBD diameter.

  • ECG — Upper abdominal pain can be inferior MI.
Admit or discharge: how is the plan decided for gallstone disease (biliary colic, cholecystitis, cholangitis)?
