About this study
Official title: Comparison of Two Management Strategies, "Endoscopy First" and "Laparoscopic Cholecystectomy First", for Patients With Gallbladder Stones and Intermediate Risk for Choledocholithiasis
The study compares two different methods to evaluate extrahepatic bile ducts for possible stones for patients with cholecystolithiasis and intermediate risk for choledocholithiasis when laparoscopic cholecystectomy is indicated.
Endosonoscopic evaluation of bile ducts and endoscopic retrograde cholangiography (ERCP) on demand are performed before laparoscopic cholecystectomy for one arm. Intraoperative cholangiography during laparoscopic cholecystectomy and postoperative ERCP on demand are administered in another arm.
Read the detailed description
Use of ERCP as a diagnostic tool should be minimized as it carries considerable risk (5 to 10%) of post-procedural complications. It is noticed that adverse events occur more often to patients with low risk of choledocholithiasis. Therefore the best possible patient selection for ERCP procedure is needed.
At the Centre of Abdominal Surgery of Vilnius University Hospital Santaros klinikos an original prognostic index (Vilnius University Hospital index (VUHI)) is used for evaluation of risk of choledocholithiasis. It is calculated by formula VUHI = A/30 + 0.4×B, where A - total bilirubin concentration (µmol/l), B - common bile duct (CBD) diameter measured by ultrasound exam. A retrospective study evaluated its accuracy and determined threshold values for low, intermediate and high risk groups. The intermediate risk group (risk for choledocholithiasis 25-75%) would benefit from additional examination before ERCP. Endoscopic ultrasound (EUS) and intraoperative cholangiography are less invasive procedures with high accuracy identifying common bile duct stones. Main hypothesis of the trial is that intraoperative cholangiography with ERCP on demand can shorten the duration and costs of treatment and avoid diagnostic ERCPs.

intraoperative cholangiographyProcedure or surgery
evaluation of bile ducts by injecting radiocontrast media to cystic duct during laparoscopic cholecystectomy
ERCPProcedure or surgery
Also called endoscopic retrograde cholangiopancreatography
evaluation of bile ducts by injecting radiocontrast media to common bile duct via endoscope inserted to duodenum
Ultrasound endoscopeDevice
Also called Endosonoscope
Endoscope with built-in ultrasound function
| Study group | Role | What they receive |
|---|---|---|
| Endoscopy first | Active comparator | Endoscopic ultrasound is used to evaluate bile ducts. If stones in extrahepatic bile ducts are seen ERCP and stone evacuation is performed during the same anaesthesia. Laparoscopic cholecystectomy is performed after endoscopic procedures in two days. Receives: Procedure: endoscopic ultrasound; Procedure: ERCP; Device: Ultrasound endoscope |
| Cholecystectomy first | Active comparator | Laparoscopic cholecystectomy with intraoperative cholangiography is performed. If stones are found postoperative ERCP with stone evacuation is applied (during cholecystectomy if common bile duct is completely blocked or as soon as possible). Receives: Procedure: intraoperative cholangiography; Procedure: ERCP |

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03658863, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Oct 2019; AzTrials last refreshed its copy on 27 Oct 2026.
