View clinical trials related to Common Bile Duct Calculi.
Filter by:Background: Pregnancy is associated with a higher risk of common bile duct stones. Currently Endoscopic Retrograde Cholangiopancreatography (ERCP) is the treatment of choice for symptomatic choledocholithiasis. However, ERCP during pregnancy is associated with hazards of radiation exposure, as well as challenging patient positioning and anesthesia
The goal of this clinical trial is to learn about Application and translational research of 3D printed models in the surgical treatment of common bile duct stones under endoscopic retrograde cholangiopancreatography. The main question it aims to answer are:Compare the differences in stone removal time, surgical complications, and surgical success rate during ERCP (+EST) surgery between 30 patients who used 3D printing preoperative simulation and 30 patients who did not use it. Participating patients will be divided into two groups, one group of 30 patients will use 3D printed models for preoperative simulation planning and then undergo surgery, and the other group will undergo surgery directly without using 3D printed models.
The modified laparoscopic transcystic biliary drainage which we developed in the treatment of cholecystocholedocholithiasis has some advantages over conventional techniques. Here, a 7-Fr triple-lumen 30-cm central venous catheter was adopted to replace conventional 5-Fr ureteral catheter, which extended the function of the C-tube. Then we developed a continued suture and circling manner by the V-Loc closure device, which simultaneously covered and anchored the C-tube. Theoretically, this modified laparoscopic transcystic drainage not only provide safe and effective bile duct drainage, but also provide a convenient access of treatment for postoperatively retained bile duct stones, which may expand the indication of initially laparoscopic operation in the management of cholecysto-choledocholithiasis.
The main aim of this clinical trial is to evaluate the effects of dexamethasone on common bile duct cannulation time during endoscopic retrograde cholangiopancreatography (ERCP) in patients with biliary pathologies. The study will also study the effects of dexamethasone on total procedure time and total fluoroscopy time during ERCP. Participants will be divided into two groups, treatment group and placebo group. Patients in treatment group will receive dexamethasone and those in placebo group will be given normal saline before undergoing ERCP. The results in both groups will be compared to determine the effects of dexamethasone.
Around 10-18% of patients undergoing cholecystectomy for gallstones have common bile duct (CBD) stones. Currently, various procedures for the treatment of cholecystocholedocholithiasis are available including open cholecystectomy plus open common bile duct exploration (OC+OCBDE), laparoscopic cholecystectomy plus laparoscopic common bile duct exploration (LC+LCBDE), may be trans-cystic or trans-choledochal, and laparoscopic cholecystectomy plus endoscopic retrograde cholangiopancreatography (LC+ERCP), which may be performed pre, at, or after LC.
The goal of this work is to assess the best time to perform LC combined with LCBD exploration and the feasibility and safety of such procedure in patients with combined GBS and CBDS after failure of ERCP extraction of CBD stones .
Assessment of the differences in stone size and the largest CBD diameter before and after stenting in one or two sessions. Stone clearance and complications were also determined with the ERCP, and factors associated with complete clearance were evaluated in patients with difficult CBD stones (a large [≥ 20 mm] or multiple [≥ 3 sized ≥ 15 mm] CBD stones). And also compared the outcomes with conventional procedure of open surgery.
Retained CBD stone after ERCP is a common problem in clinical practice. This study aimed to evaluate the effect of saline irrigation of common bile duct after complete stone removal considered by ERCP in the reduction of residual CBD stone and the effect on clinical outcome.
Overall stone clearance with endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis is a big problem, especially for stones with a diameter greater than 3cm. After ERCP failure, surgery was the option but patients not suitable for surgery were treated through stenting but had to undergo multiple ERCPs and show a success rate of only 44-96%. Recently, choledochoscopic laser, electrohydraulic lithotripsy, SpyGlass, or extracorporeal shock wave lithotripsy (ESWL) have been applied for the treatment of huge bile duct stones. The present study aims to compare the efficacy and safety outcomes of SpyGlass direct vision lithotripsy and ESWL procedures for the removal of large bile duct stones.
The aims of this study are to compare the needle knife fistulotomy (NKF) technique versus the partial ampullary endoscopic mucosal resection (PA-EMR) technique in patients with difficult biliary cannulation and to assess the incidence rate of complications between these cannulation methods.
