Percutaneous cholangiostomy for portal cholangiocarcinoma

Abstract

to analyze the efficacy of interventional methods in treatment of Klatskin tumor patients. Treatment of 133 patients with Klatskin tumor for the period 2000-2015 was analyzed. Bismuth I type was revealed in 28 (21.1%) cases, type II - in 45 (33.8%) cases, type III - in 51 (38.3%) cases, type IV - in 9 (6.8%) cases. All patients underwent sonofluoroscopy-assisted percutaneous transhepatic cholangiostomy using self-fixing Pig tail 8Fr drains at the first stage followed by externointernal drainage or antegrade biliary stenting. We deployed 1-6 drains simultaneously or step by step depending on severity of biliary occlusion. Technical success was achieved in all patients. Major postoperative complication such as drain dislocation followed by advanced biliary peritonitis was observed in 1 (0.8%) case. Minor complications occurred in 22 (16.5%) patients. In-hospital mortality was 7.5% (10 patients). The cause of death was severe liver-renal failure. Liver abscesses occurred in 13 patients after transpapillary externointernal drainage on background of temporary occlusion of biliary drain. This required interventional surgery. Obstructive jaundice management should be performed using interventional techniques simultaneously or step by step if unresectable tumor or inoperable patient are present. Herewith it is advisable to restore bile flow in maximal volume of liver parenchyma. Use of uncovered self-expanding biliary stents for palliative treatment of Klatskin tumor may be realized in «hybrid» variant to control stent patency as well as for neoadjuvant therapy of tumor.
