97 Performance Comparison Between Endoscopic Ultrasound/endoscopic Retrograde Cholangiopancreatography and Intraoperative Cholangiography for Detecting Choledocholithiasis

Abstract Background: The optimal approach for patients with gallbladder stones and intermediate risk for choledocholithiasis still remains undetermined. Use of diagnostic endoscopic retrograde cholangiopancreatography should be minimized as it carries considerable risk of post-procedural complications. This study compares two different management strategies: intraoperative cholangiography and endoscopic ultrasound before laparoscopic cholecystectomy for patients with symptomatic cholecystolithiasis and intermediate risk for choledocholithiasis. Methods: It is a diagnostic randomized active-controlled single-centre clinical trial enrolling adult patients undergoing laparoscopic cholecystectomy due to symptomatic gallbladder stones with intermediate risk for choledocholithiasis. The risk for choledocholithiasis is calculated using an original prognostic score – Vilnius University Hospital Index. A total of 106 participants will be included and randomized into two groups. Evaluation of bile ducts using endoscopic ultrasound and endoscopic retrograde cholangiography on demand will be performed before laparoscopic cholecystectomy for one arm (“Endoscopy first”). Intraoperative cholangiography during laparoscopic cholecystectomy and postoperative endoscopic retrograde cholangiopancreatography on demand will be administered in another arm (“Cholecystectomy first”). Postoperative follow-up is 6 months. The primary endpoint is the length of hospital stay. Secondary endpoints will include accuracy of the different management strategies, adverse events of interventions, duct clearance and technical success of interventions (intraoperative cholangiography, endoscopic ultrasound, endoscopic retrograde cholangiography), costs of treatment. Discussion: This trial is planned determine which strategy is better approach for a patient with intermediate common bile duct stones risk and to define a simple to calculate and safe algorithm on managing choledocholithiasis. Trial registration: The trial is registered at ClinicalTrials.gov, identification number NCT03658863.
