Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Endoscopy first

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.

Group Type ACTIVE_COMPARATOR

endoscopic ultrasound

Intervention Type PROCEDURE

Evaluation of bile ducts with endoscope with special ultrasonographic function

ERCP

Intervention Type PROCEDURE

evaluation of bile ducts by injecting radiocontrast media to common bile duct via endoscope inserted to duodenum

Cholecystectomy first

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).
