Active clinical trials for "Bile Duct Diseases"

Selective bile duct cannulation is the most important step in endoscopic retrograde cholangiopancreatography (ERCP) for treatment of benign and malignant pancreatobiliary diseases, but it may fail in up to 15% of cases. Precut papillotomy is an advanced ERCP cannulation technique recommended by guidelines for rescue of difficult biliary access, but it is not without limitations. Endoscopic ultrasound (EUS)-guided biliary drainage is a novel interventional EUS technique that has been increasingly performed after failed biliary access by advanced ERCP cannulation techniques.

Pancreaticoduodenectomy, as a standard surgical procedure for malignant tumors of the head of the pancreas, ampulla and distal common bile duct, has brought the hope of clinical cure for these diseases.In the whole surgical process, the resection of the uncinate process of the pancreas is considered to be a major difficulty in the whole operation, which can affect the rehabilitation process and long-term prognosis. Two main methods have been developed around the dissection of the uncinate process of the pancreas. One is the Venous-first approach based on the portal vein-superior mesenteric vein axis. The other is the Artery-first approach that first explores whether the superior mesenteric artery is invaded by the tumor to judge resectable. The latter is gradually promoted in clinical practice because it can reduce intraoperative bleeding, reduce postoperative complications, and improve long-term prognosis. The intermediate approach is a surgical approach based on the Artery-first approach and adapted to the layout of the robot arm. The area between superior mesenteric artery and superior mesenteric vein was used as an intermediate area to treat the uncinate process of the pancreas in order to reduce perioperative complications and achieve better surgical results. However, the safety and effectiveness of intermediate approach have not been verified,in this prospective clinical study, the investigators will use a robotic surgical platform to perform robot-assisted pancreaticoduodenectomy surgery through the intermediate approach to verify its safety and efficacy.

Primary sclerosing cholangitis (PSC) is chronic fibroinflammatory disease of the liver. There is still no medical therapy proven to halt the progression of PSC or prevent its serious complications. This is a Phase 2 randomized, double bind, placebo-controlled, monocentric study evaluating the safety and efficacy of two doses of oral vancomycin (i.e. 750 mg and 1500 mg/day) in subject between 15 - 70 years old with PSC.

Endoscopic ultrasonography (EUS) is a key procedure for diagnosing biliopancreatic diseases. However, the performance among EUS endoscopists varies greatly and leads to blind areas during operation, which impaired the health outcome of patients. We previously developed an artificial intelligence (AI) device that accurately identifies EUS standard stations and significantly reduces the difficulty of ultrasound image interpretation. In this study, we updated the device (named EUS-IREAD) and assessed its performance in improving the quality of EUS examination in a single-center randomized controlled trial.

This phase III trial studies how well thoracic epidural analgesia or four-quadrant transversus abdominus plane block works in reducing pain in patients undergoing liver surgery. It is not yet known whether thoracic epidural analgesia or four-quadrant transversus abdominus plane block may help people to recover more completely and more quickly after surgery.

This trial studies how well electronic neurocognitive tools work in screening for mental capability in patients who are undergoing liver surgery. Using electronic neurocognitive screening tools may help to better assess mental impairment.

laparoscopic pancreaticoduodenectomy(LPD) and Robot Pancreaticoduodenectomy (RPD), as two minimally invasive methods of pancreaticoduodenectomy(PD), have obvious advantages over traditional open pancreaticoduodenectomy(OPD) in terms of reducing surgical trauma and hospitalization time, but there are few studies on their perioperative safety and prognostic effects.However, there are few studies on the perioperative safety and prognostic effects of both procedures. In this trial, the perioperative data and prognosis of both procedures were collected and analyzed through a prospective, multicenter approach to investigate the advantages and disadvantages of both procedures.

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.

Further studies are needed to investigate the prognosis and perioperative safety of patients undergoing robotic-assisted pancreaticoduodenectomy. In this study, clinical data and prognostic data of patients undergoing this procedure were prospectively collected and analyzed to explore its safety and efficacy.
