What is the role of What is the role of EUS in cholelithiasis?EUS in cholelithiasis?
EUS in cholelithiasis
• History
• Instruments
• EUS for cholecystolithiasis
• EUS for choledocholithiasis
• Conclusions and future of EUS in gallstones
History of EUS in clinical practice• Started as a technique to image organs
outside GI-tract (US, start of ERCP, no CT, no MR)
• Staging of luminal tumors quickly followed (esophagus, stomach, colorectum)
• Next major breakthrough: EUS-guided FNA
• 2009: non-invasive staging by excellent CT & MR
• 2010+: EUS for early diagnosis and guided Rx
EUS in cholelithiasis

Instruments & Accesories
High-end US processors (Aloka, Hitachi. ...)
• Elastography
• Tissue Harmonic Imaging
• Contrast Enhanced EUS
• .......
Instruments & Accesories• 360° Radial array
vs. Linear array

EUS in cholecystolithiasis• Transabdominal US is standard for
galbladder stones
• EUS may be useful in case of:– Multiple very small stones (sludge)
– Poor imaging because of obesity
• Indication for EUS in cholecystolithiasis– Strong suspicion of gallbladder stones
with negative non-invasive imaging
EUS in cholecystolithiasis
• 35 pts with biliary type pain and negative US
• EUS showed suspicion of stones in 18pts (52%)
• 15/17 proven during surgery
• 13/15 symptomfree at one year FU

EUS in choledocholithiasis• Imaging of CBD is not so difficult
anymore with excellent new equipment
• Experience is important (50-100/year)
• EUS only in low-probablility for CBD-stones?
• Should every ERCP for stones be preceded by EUS?
• How about acute pancreatitis?
EUS in choledocholithiasis
EUS in choledocholithiasis
EUS in choledocholithiasis
• ERCP vs. EUS +/- ERCP• 65pts with elevated LFT’s or dilated
CBD (8 or 10mm)• ERCP: 7/32 pts (22%) with CBD-stones• EUS +/- ERCP: 9/33pts (27%) CBD-
stones• 1pt in each group recurrent symtoms
EUS in choledocholithiasis
• 4 trials selected (423pts)
• In EUS group, ERCP was avoided in 74%
• EUS significantly reduced risk of ERCP associated complications
EUS in choledocholithiasis
risk of acute pancreatitis

• Conclusions and future of EUS in gallstones
Conclusions & future use• EUS is most sensitive technique for
CBD-stones, more sensitive than MRCP
• EUS is invasive and requires expertise
• Restriction of ERCP to (very) experienced seems imminent (raise req/yr from 40100)
• Combine EUS with ERCP in:– Unexplained obstrcutive jaundice
– All pts referred for treatment of CBD-stones
