Abstract:
Objective To explore the reasons of biliary restenosis after interventional treatment for malignant obstructive jaundice caused by hepatic hilar cholangiocarcinoma and to discuss its management. Methods During the period from June 2010 to Sep. 2013 at authors’ hospital, a total of 36 patients with high biliary obstruction caused by Bismuth Ⅱ - Ⅳ type of hepatic hilar cholangiocarcinoma received percutaneous transhepatic cholangial stenting (PTCS), and as the patients developed biliary restenosis after PTCS percutaneous transhepatic cholangial drainage (PTCD) had to be carried out. All the patients had complete data. Serum total bilirubin, direct bilirubin, glutamyltranspetidase and alkaline phosphatase levels were determined on the operation day and at five days after PTCS and PTCD. The short - term remission of malignant obstructive jaundice produced by PTCS and PTCD were assessed. The causes of biliary restenosis were analyzed by comparing the CT and/or MRI images as well as the cholangiography and drainage test results which were performed at the first and second admission to hospital. Results The interval time from operation to restenosis was 31 - 468 days, with an average of 132.8 days. The effective rates of PTCS and PTCD for relieving jaundice were 77.8% and 75.0% respectively. The main causes of restenosis included the formation of biliary sludge, acute cholangitis and tumor growth. Conclusion PTCS is an effective means to relieve the malignant obstructive jaundice caused by hepatic hilar cholangiocarcinoma, however, the incidence of biliary restenosis after PTCS is higher, which may be mainly due to the tumor growth. Nevertheless, subsequent PTCD can effectively improve the liver function, control biliary infection, remit biliary obstruction and relieve the clinical symptoms.
