Active clinical trials for "Choledocholithiasis"

The incidence of choledocholithiasis is gradually rising with the increase of gallstone incidence. The popular minimally invasive treatment options include endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic common bile duct exploration (LCBDE). Currently, three-dimensional (3D) video system for laparoscopy is developed to ofer surgeon a superior depth perception and a much better user experience, thus potential increasing operation accuracy and stability. It have suggested that compared with 2D laparoscopy, 3D laparoscopy can effectively reduce operation time and numbers of errors. However, rare experimental studies are performed to evaluate the safety and effectiveness of 3D laparoscopy in choledocholithiasis patients. The aim of this study is to compare the perioperative outcomes between 3D laparoscopy and ERCP in choledocholithiasis patients through a multicenter randomized controlled design.

Carbon dioxide (CO2) gas is widely used for luminal insufflation during endoscopic retrograde cholangiopancreatography (ERCP) of the biliary tract. While frequently observed during routine ERCP, there are few data on the topic of "air" or "CO2" cholangiography. Our primary aim is to compare radiographic cholangiograms in patients with biliary tract disease (from stones or strictures) during ERCP obtained by using carbon dioxide as the contrast medium vs. conventional iodinated contrast.

The management of coexisting intrahepatic bile duct (IBD) and extrahepatic bile duct (EBD) stones is complicated and requires a multidisciplinary approach. The long-term clinical outcomes of patients initially treated with endoscopic retrograde cholangiopancreatography (ERCP) EBD stone extraction remain unclear. Investigators conducted a retrospective study of patients with coexisting IBD and EBD to investigate the long-term impact of ERCP on the incidence of recurrent EBD stones and to identify risk factors of recurrence.

The Percutaneous Cholangiopancreatoscopy (PCPS) registry is an observational, multicentric, prospective, and retrospective registry of patients undergoing the percutaneous cholangiopancreatoscopy procedure at sites across the United States. In the retrospective component of the study, clinical and procedural data regarding patients who have undergone clinical indicated percutaneous cholangiopancreatoscopy procedure in the past will be collected from all the registry sites and stored in a secure database. The prospective component of the registry will run for three years at each site where patients undergoing the clinically indicated percutaneous cholangiopancreatoscopy procedure will be enrolled in the study, and the patients' data will be collected whenever the patients present to interventional radiology (IR) for a procedure or clinic visit.

This is a prospective, multi-centre trial conducts at 4 ERCP centers in China designed to determine if chronic gallbladder diseases increase the incidence of Post-Endoscopic Retrograde Choledochopancreatography-Choledocholithiasis (PEC）

We planned this multicenter randomized controlled trial to study the role of a prophylactic biliary stent in recurrence of stones and biliary complications in patients awaiting cholecystectomy after biliary stone clearance

The aim of the trial is to compare two operations which are used to treat bile duct stones. The hypothesis of the study is that there is no difference between endoscopic sphincterotomy followed by laparoscopic cholecystectomy or laparoscopic bile duct exploration during laparoscopic cholecystectomy in the treatment of bile duct stones in higher risk patients.

Gallstone is a worldwide clinical problem which affecting most of the populations with incidence of 15 to 20% in west and 10% in Asians. About 5 to 15% of patient with gallstone will go on to develop bile duct calculi. There are several endoscopic strategies developed for treatment of common bile duct stone such as endoscopic sphincterotomy (EST), endoscopic papillary large balloon dilatation (EPLBD) and combination of EST plus EPLBD. Our aim of this study is to compare efficacy, and safety of EST alone group versus EST plus EPLBD group in removing CBD stone.

For endoscopist, ERCP for bile duct stone removal is the most widely performed procedure. However, the risk associated radiation exposure to patients and staff are not neglible. Earlier studies, ERCP without the use of fluoroscopy has been reported high success for bile duct stone removal in pregnant patients to prevent radiation exposure to the fetus. EUS is highy accurate technique in detecting common bile duct stone and guiding for therapeutic intervention. There has been a few data from literature showed that EUS guided CBD stone ( CBDS ) removal are equivalent to those following ERCP in term of successful CBDS removal and complications. This randomized trial is designed to address the question that EUS guided CBDS removal is equivalent to ERCP in term of efficacy and safety.

Recently up-coming drug, etomidate which is a modulator of GABA(gamma-Aminobutyric acid)-A receptor has been known that it maintains the appropriate sedative levels and affects little effects on respiratory system. The investigators are now trying to investigate that etomidate with meperidine combination regimen is superior to the midazolam with meperidine more effective and less harm on sedation during the ERCP procedure.
