Abstract:
Objective To evaluate the approaches of percutaneous trans-hepatic stent for relieving malignant biliary obstruction and its clinical effect. Methods 20 stents were set up in bile duct to treat malignant biliary obstruction in 18 cases using two steps under x-ray fluoroscopy. After the stents set up successfully, the contrast agent was injected through the long sheath in order to find out the expansion and expedition of the stent. The stents were provided by Micro-Tech co.1td.(Nanjing). The patient’s jaundice, liver function and amylase (AMY)levels were observed after the procedure and all the patients were followed up for three to eleven months. Results Twenty stents were placed in 18 patients successfully in one time.STB , ALT, AST, r-GT and ALP decreased 66.27%, 57.83%, 62.21%, 44.74% and 47.57% respectively one week after the procedure. Early complications included hyperamylasemia , acute pancreatitis,hernobilia, bile leakage,ect.Late complications were displacement and restenosis of the stent . A patient died due to failure of heart and lung. Conclusion The percutaneous transhepatic insertion of biliary stent is an effective method in relieving malignant obstructive jaundice.
