Teaching Points
Teaching Points
- The aim of investigation is to identify and treat patients with common bile duct (CBD) stones prior to surgery
- Low probability of a stone - normal liver function tests (LFTs), normal CBD on ultrasound, previously abnormal LFTs or past history of pancreatitis
- High probability of a stone - cholestatic jaundice, abnormal LFTs, abnormal CBD on trans-abdominal ultrasound or current episode of pancreatitis
- If surgical expertise in laparoscopic cholecystectomy, intra-operative cholangiogram and laparoscopic stone removal is available proceed directly to this option
- Non-invasive methods of evaluation include CT cholangiography, MR cholangiopancreatographyy and endoscopic US (EUS)
- Endoscopic retrograde cholangiopancreatography (ERCP) enables retrieval of CBD stones prior to surgery
ct
Computed Tomography (CT) Cholangiogram
- >90% sensitivity and specificity for detection of bile duct stones 25,26,27
- Alternative for detection of CBD stones in intermediate risk group, if MRCP or EUS unavailable 25,26,27
- Used by some surgeons, to evaluate aberrant bile ducts before laparoscopic cholecystectomy 28
- Disadvantages
- Unsuccessful if bilirubin levels are more than twice the upper limit of normal
- Potential risk of contrast toxicity
- Radiation exposure
- Does not offer therapeutic opportunity
ercp
Endoscopic Retrograde Cholangiopancreatography (ERCP)
- Routine use of ERCP to detect common bile duct stones before laparoscopic cholecystectomy is not indicated in low risk groups 3,9,11
- ERCP is indicated before laparoscopic cholecystectomy in patients in whom there is high clinical suspicion of choledocholithiasis, based on clinical, biochemical and ultrasonographic criteria 3,10,11,12,13
- Highly accurate in diagnosis and treatment of common bile duct stones (96% success rate for endoscopic sphincterotomy) 3,10,11,12,14
- Limitations - up to 5% complication rate (e.g. pancreatitis), ~0.5-1% mortality rate and ~8% cannulation failure rate 11,12,13,15
eus
Endoscopic Ultrasound (EUS)
- Highly accurate (>95%) for the detection of choledocholithiasis (comparable to ERCP but superior to CT and US) 3,4,6,7,18,19,20,21,32
- No significant difference in diagnostic accuracy compared to MRCP. 32 Consider patient suitability, availability and local expertise in selecting appropriate modality 33
- Comparable sensitivity to that of ERCP for detection of choledocholithiasis 18,19
- Can be used to detect common bile duct stones in intermediate risk group who are good surgical candidates 3,18,22
- Not suitable in 19
- Severe acute biliary pancreatitis or cholangitis, since it may delay endoscopic treatment
- In elderly and high-risk surgical patients because in this population the treatment of choice is endoscopic sphincterotomy if CBD stones are detected
- Limitations
- Limited availability
- Invasive
- Technically impossible in cases of previous gastric surgery
- Difficult to interpret following sphincterotomy or previous biliary stenting procedures due to presence of air in the biliary tract
- Does not offer therapeutic opportunity
high
High Risk Features
- Patients with the following clinical, biochemical, or sonographic features are considered at high risk of having a CBD stone
- Cholestatic jaundice
- Abnormal liver function tests
- Abnormal CBD on US (i.e. dilated ducts, CBD stones)
- Current episode of pancreatitis
low
Low Risk Features
- Patients with the following clinical, biochemical, or sonographic features are considered at low risk of having a CBD stone
- Normal liver function tests
- Normal CBD on ultrasound
- Previously abnormal LFTs and past history of pancreatitis remains low risk
mrcp
Magnetic Resonance Cholangiopancreatography (MRCP)
- Sensitivity of over 84% and specificity of over 90% for the diagnosis of CBD stones, with most false negative results being for stones less than 5mm in diameter 21,23,24,25,31,32
- A meta-analysis of 7 studies showed no statistically significant difference in diagnostic accuracy between MRCP and EUS for the detection of CBD stones. 32 Consider patient suitability, availability and local expertise in selecting appropriate modality 33
- Advantages
- Non-invasive
- No ionising radiation
- Allows diagnosis and treatment planning without invasive cholangiography
- Limitations
- Does not offer therapeutic opportunity
- Expensive and limited availability
- Less sensitive for stones smaller than 5mm in diameter 31
us
Ultrasound
- Has a sensitivity of 36-75% and specificity of 83-97% for the diagnosis of CBD stones 5,8,16,17,29,30
- Limitations 8
- False negative results due to inability to see the extra-hepatic biliary tree (often because of interposed bowel gas) and absence of biliary dilation in the presence of obstruction
- Advantages
- Non-invasive and readily available
- No ionising radiation
