Filter by: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 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.
