Abstract:

From January 2003 till January 2008 transhepatic endobiliar stenting was performed in 62 patients with obstructive jaundice due to high post-operative malignant strictures of hepaticocholedochus duct. In 49 cases (79 %) two-step intervention performed (biliary drainage followed by endobiliary stenting), 13 patients (21 %) underwent single-stage intervention. In 60 patients (96,8%) balloon dilatation was done prior to stent implantation. In 59 cases (95,2%) the procedure was completed by control drainage placement. Hospital stay for the endobiliary stenting procedure was 12,7-22,3 days (average hospital stay 17,5 days). Mortality was as high as 12,9% (8 cases). Average post-implantation life span appeared to be 9,7 months. In 5 patients (8,1%) mechanical jaundice relapse occurred, so they needed hospitalization for reintervention. Direct dependence found between the effectiveness of endobiliary stenting and the technical characteristics of stents, anatomy of biliary strictures, as well as the methods and techniques of the intervention. Single-stage endobiliary stenting, without prior drainage, decreases the complication rate, improves the quality of life during the hospital stay, and prolongs the post-implantation life expectancy. Single-stege interventions are also shown to decrease the hospital stay and reduce the costs. Balloon dilatation is the required stage of the intervention, especially if self-expandable stents are used in torturous biliary ducts. Post-implantation drainage placement can be skipped if the wall of the hepatico-choledochus duct is not edematous, there are no signs of tumor prolapse into the lumen, if the stent is completely expanded, and the contrast media evacuates easily into the intestine.
