BackgroundCholedocholithiasis is one of the causes of jaundice and may require urgent treatment. Endoscopic retrograde cholangiopancreatography (ERCP) has been the primary management strategy for choledocholithiasis. However, small stones can be overlooked during ERCP.AimThe aim of this study was to evaluate the accuracy of intraductal ultrasonography (IDUS) for detecting choledocholithiasis in icteric patients with highly suspected common bile duct (CBD) stones without definite stone diagnosis…

Endoscopic Extraction of Biliary Fascioliasis Diagnosed Using Intraductal Ultrasonography in a Patient with Acute Cholangitis
TLDR
A case of biliary fascioliasis is presented that was diagnosed using IDUS and managed endoscopically in a patient with acute cholangitis and can be confirmed by extraction of the leaf-like trematode from the bile duct.
Comparing cost-effectiveness between endoscopic ultrasound and endoscopic retrograde cholangiopancreatography in diagnosis of common bile duct stone in patients with predefined risks: A study from a developing country
TLDR
EUS is safer and less costly than ERCP for CBD stone diagnosis in patients with intermediate risk, and the EUS-based strategy was cost-saving when the CBD stone prevalence was less than 52.5%.
Intraductal Ultrasound for High-Risk Patients: When Will the Last Be First?
TLDR
It is clear that EUS or, alternatively, magnetic resonance cholangiopancreatography (MRCP) is required to plan optimal therapeutic strategy, and the sensitivity of MRCP is decreased in the setting of small CBD stones, whereas EUS remains highly sensitive even for small stones.
Irrigation-assisted intraductal ultrasonography with a 3-Fr microcatheter during endoscopic retrograde cholangiography.
TLDR
Simultaneous irrigation via the microcatheter during IDUS ameliorates acoustic coupling and produces reliable examinations that are suitable for the evaluation of the wall layers in patients with pneumobilia, as well as for the detection of stones.
The role of intraductal ultrasonography in pancreatobiliary diseases
Intraductal ultrasonography (IDUS) provides real-time, cross-sectional imaging of pancreatobiliary ducts and surrounding structures during endoscopic retrograde cholangiopancreatography using a…
Saline Solution Irrigation of the Bile Duct after Stone Removal Reduces the Recurrence of Common Bile Duct Stones.
TLDR
It is demonstrated that subsequent biliary irrigation after stone removal may prevent the recurrence of CBD stones by clearing small residual fragments during follow-up, as well as the need for mechanical lithotripsy, which was used for stone fragmentation, as a risk factor.
Effects of Saline Irrigation of the Bile Duct to Reduce the Rate of Residual Common Bile Duct Stones: A Multicenter, Prospective, Randomized Study
TLDR
Considering the efficacy and safety, routine PSIB after endoscopic CBD stone removal seems to be preferred (ClinicalTrials.gov identifier: NCT01425177).
Endoscopic Ultrasound and Fine-Needle Aspiration for Pancreatic and Biliary Disorders
Intraductal ultrasonography in pancreatobiliary diseases
TLDR
Intraductal ultrasonography (IDUS) utilizes probe catheter and operates at a higher frequency (12–30 MHz) and provides real-time, high-quality imaging of pancreatobiliary ducts and the surrounding structures.
Various innovative roles for 3‐Fr microcatheters in pancreaticobiliary endoscopy
TLDR
It is believed that 3‐Fr microcatheters offer effective and safe salvage troubleshooting during various endoscopic pancreaticobiliary procedures that face troublesome situations with conventional strategies.

Selective endoscopic cholangiography for the detection of common bile duct stones in patients with cholelithiasis.
TLDR
Preoperative selective ERCP is effective in detecting clinically significant CBD stones, however, there is a high false-negative rate when a single criterion is used to guide therapy.
Clinical utility of intraductal US for evaluation of choledocholithiasis.
TLDR
Selective use of intraductal US affects the clinical management of a large proportion of patients who undergo C-arm fluoroscopy-guided ERCP for suspected bile duct stones.
Detection of choledocholithiasis by EUS in acute pancreatitis: a prospective evaluation in 100 consecutive patients.
TLDR
EUS is more sensitive than US in detecting biliary stones in patients with acute pancreatitis and is as accurate as ERCP in detecting choledocholithiasis, thus avoiding diagnostic E RCP and its associated potential for complications in the majority of patients.

The Detection of Bile Duct Stones in Suspected Biliary Pancreatitis: Comparison of MRCP, ERCP, and Intraductal US
TLDR
MRCP can be used to select patients with biliary pancreatitis who require ERCP and the combination of E RCP and IDUS improved accuracy in the diagnosis of choledocholithiasis.

Wire-guided intraductal US: an adjunct to ERCP in the management of bile duct stones.
TLDR
IDUS improves diagnostic accuracy of ERC and is a useful adjunct to ERC when bile duct stones are suspected, and this aim was to determine whether intraductal US improves the accuracy of cholangiography and whether it is a Useful adjunct in the management of bileduct stones.
Over-the-wire US catheter probe as an adjunct to ERCP in the detection of choledocholithiasis.
TLDR
Intraductal ultrasound as an adjunct to ERCP for detection of extrahepatic bile duct stones is technically easy, accurate, and safe and IDUS differentiates stones from air bubbles and prevents unnecessary sphincterotomy.
