Filter by:Covered self expandable metal stents (CSEMS) are three times larger in diameter than 10 Fr plastic stents. When compared to plastic stents, randomized trials have shown longer patency and fewer stent-related complications for CSEMS. The investigators hypothesize that placement of CSEMS would be a better treatment option for preoperative biliary decompression in patients with pancreatic cancer.
Preoperative biliary drainage methods include percutaneous transhepatic biliary drainage (PTBD), endoscopic nasobiliary drainage (ENBD), and endoscopic retrograde biliary drainage (ERBD). Endoscopic biliary drainages often induce peritumoral inflammation and it increase difficulties in determining a proper resection margin. The purpose of this study is to compare the clinicopathological outcomes according to the methods of preoperative biliary drainage in periampullary cancers causing obstructive jaundice, and to find out a proper biliary drainage method.
Introduction: Cholemia and bacterial translocation with portal endotoxemia are integral in the pathogenesis of obstructive jaundice (OJ). There is sufficient experimental data about hemodynamic and histopathologic consequences of OJ. On the contrary, pathologic information of renal changes in patients with OJ is still lacking. Therefore; the primary objective of this prospective study is to demonstrate the specific histopathologic changes in kidneys of patients with short-term biliary tract obstruction receiving a standard perioperative medical treatment protocol.
Cancer of the gallbladder (CaGB) is one of the most common causes of malignant obstructive jaundice. Jaundice is the second most common presentation and occurs in 30-60% of patients with CaGB. It is obstructive in nature and frequently associated with pruritus, which is very disturbing for the patients. The usual mechanism of obstruction is direct infiltration of the bile duct by the tumour. Most patients with CaGB with obstructive jaundice are not amenable to a curative surgical resection and hence effective palliation is the goal of treatment. Although surgical bypass has been the traditional palliative approach, it is associated with substantial morbidity and mortality. Non-operative alternatives in the form of percutaneous and endoscopic drainage are available. A few trials have shown that endoscopic drainage is better than percutaneous drainage in patients with lower end bile duct obstruction due to pancreatic and peri-ampullary cancer. However, the scenario is quite different in patients with upper end of bile duct obstruction as occurs due to CaGB. Endoscopic drainage is associated with a higher incidence of cholangitis in patients with a block at the upper end of the bile duct and the success rate varies from 40% to 80%, while percutaneous drainage may be associated with complications such as biliary leak and bleeding. There has been no randomized trial comparing endoscopic and percutaneous drainage in patients with malignant obstruction due to CaGB. The objective of the present study is to carry out a randomized prospective trial comparing percutaneous and endoscopic biliary drainage in patients with CaGB with obstructive jaundice and to assess their quality of life.
This study compares the 6 mm nitinol Zilver biliary endoprostheses and the 10 mm nitinol Zilver biliary endoprostheses to the 10 mm Wallstent in appropriate patients in need of palliative treatment of malignant obstructive jaundice.
