Cholangitis/ Cholecystitis Flashcards
Define cholangitis
Obstruction of the common bile duct by stones
Causes of cholangitis
When a stone moves to obstruct the common bile duct → Bile duct infection, biliary obstruction
(also caused by strictures, stenosis, parasites, tumours)
Symptoms and signs of cholangitis
Symptoms: pyrexia, RUQ pain, jaundice, mental status change, tachycardia, hypotension
Signs: Charcot’s triad – RUQ pain, jaundice, rigors
(Reynold’ pentad when combined with ↓BP and confusion)
Define cholecystitis
inflammation of the gallbladder
Causes of cholecystitis
Types of Stones that block CBD
Symptoms of cholecystitis
- Systemically unwell
- Fever
- Vomiting
- Prolonged abdominal pain - epigastric or RUQ
- Pain may be referred to right shoulder (due to diaphragmatic irritation)
- ±jaundice
Signs of cholecystitis
- Tachycardia
- Pyrexia
- RUQ pain or epigastric tenderness
- May be guarding or rebound tenderness
- Murphy’s sign positive: 2 fingers over RUQ and ask pt to breathe in deeply, +ve if this causes pain and arrest of inspiration as inflamed GB hits fingers (must not cause the same pain in the LUQ)
US → thick walled shrunken GB, pericholecystic fluid, stones, CBD dilation
Investigations
Bloods
- FBC - high WCC in cholecystitis and cholangitis
- LFT - high ALP + GGT in ascending cholangitis
- Blood cultures
- Amylase (exclude pancreatitis)
Ultrasound
- Shows gallstones
- Increased thickness of gallbladder wall
- Dilatation of biliary tree
AXR - but only 10% of gallstones are radio-opaque
Other imaging - to exclude differentials (e.g. erect CXR, ERCP)
Management
Conservative
- If only mild biliary colic - follow a low-fat diet
Medical
- NBM
- IV fluids
- Analgesia
- Anti-emetics
- Antibiotics (if infection is present)
- NOTE: if symptoms persist despite antibiotic treatment, suspect a localised abscess or empyema, which would require drainage
- If there is an obstruction, urgent biliary drainage by ERCP or via a percutaneous route is necessary
Surgical
- Laparoscopic Cholecystectomy
Complications
Stones within the gallbladder
- Biliary colic
- Cholecystitis
- Gallbladder empyema
- Gallbladder cancer (RARE)
Stones outside the gallbladder
- Obstructive jaundice
- Pancreatitis
- Ascending cholangitis
- Cholecystoduodenal fistula
- Gallstone ileus
- Bouveret syndrome (gallstones cause gastric outlet obstruction)
- Mirizzi syndrome
Complications of cholecystectomy
- Bleeding
- Infection
- Bile leak
- Post-cholecystectomy syndrome
- Port-site hernia
Prognosis
Gallstones do NOT cause symptoms most of the time
Surgery offers an excellent chance of cure if they were to become symptomatic
