BACKGROUND: Endoscopic retrograde cholangiography is highly accurate in diagnosing choledocholithiasis, but it is the most invasive of the available methods. Endoscopic ultrasonography is a very accurate test for the diagnosis of choledocholithiasis with a risk of complications similar to that of upper gastrointestinal endoscopy. AIM: To compare the accuracy of endoscopic ultrassonography and endoscopic retrograde cholangiography in the diagnosis of common bile duct stones before laparoscopic cholecystectomy and to analyze endoscopic ultrasound results according to stone size and common bile duct diameter. PATIENTS AND METHODS: Two hundred and fifteen patients with symptomatic gallstones were admitted for laparoscopic cholecystectomy. Sixty-eight of them (31.7%) had a dilated common bile duct and/or hepatic biochemical parameter abnormalities. They were submitted to endoscopic ultrassonography and endoscopic retrograde cholangiography. Sphincterotomy and sweeping of the common bile duct were performed if endoscopic ultrassonography or endoscopic retrograde cholangiography were considered positive for choledocholithiasis. After sphincterotomy and common bile duct clearance the largest stone was retrieved for measurement. Endoscopic or surgical explorations of the common bile duct were considered the gold-standard methods for the diagnosis of choledocholithiasis. RESULTS: All 68 patients were submitted to laparoscopic cholecystectomy with intraoperative cholangiography with confirmation of the presence of gallstones. Endoscopic ultrassonography was a more sensitivity test than endoscopic retrograde cholangiography (97% vs. 67%) for the detection of choledocholithiasis. When stones >4.0 mm were analyzed, endoscopic ultrassonography and endoscopic retrograde cholangiography presented similar results (96% vs. 90%). Neither the size of the stone nor the common bile duct diameter had influence on endoscopic ultrasonographic performance. CONCLUSIONS: For a group of patients with an intermediate or moderate risk with respect to the likelihood of having common bile duct stones, endoscopic ultrassonography is a better test for the diagnosis of choledocholithiasis when compared to endoscopic retrograde cholangiography mainly for small-sized calculi.

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.

BackgroundMagnetic resonance cholangiography (MRC) is a new technique for non-invasive imaging of the biliary tract.AimTo assess the results of MRC in patients with suspected bile duct stones as compared with those obtained with reference imaging methods.Patients/Methods70 patients (34 men and 36 women, mean (SD) age 71 (15.5) years; median 75) with suspected bile duct stones were included (cholangitis, 33; pancreatitis, three; suspected post-cholecystectomy choledocholithiasis, nine; cholestasis, six; stones suspected on ultrasound or computed tomography scan, 19). MR cholangiograms with two dimensional turbo spin echo sequences were acquired. Endoscopic retrograde cholangiography with or without sphincterotomy (n = 63), endosonography (n = 5), or intraoperative cho- langiography (n = 2) were the reference imaging techniques used for the study and were performed within 12 hours of MRC. Radiologists were blinded to the results of endoscopic retrograde cholangiography and previous investigations.Results49 patients (70%) had bile duct stones on reference imaging (common bile duct, 44, six of which impacted in the papilla; intrahepatic, four; cystic duct stump, one). Stone size ranged from 1 to 20 mm (mean 6.1, median 5.5). Twenty seven patients (55%) had bile duct stones smaller than 6 mm. MRC diagnostic accuracy for bile duct lithiasis was: sensitivity, 57.1%; specificity, 100%; positive predictive value, 100%; negative predictive value, 50%.ConclusionsStones smaller than 6 mm are still often missed by MRC when standard equipment is used. The general introduction of new technical improvements is needed before this method can be considered reliable for the diagnosis of bile duct stones.
