BACKGROUND We examined the efficacy and toxicity of proton beam therapy (PBT) for treating advanced cholangiocarcinoma. METHODS The clinical data and outcomes of 28 cholangiocarcinoma patients treated with PBT between January 2009 and August 2011 were retrospectively examined. The Kaplan-Meier method was used to estimate overall survival (OS), progression-free survival (PFS), and local contro...
Hilar cholangiocarcinoma (CC) is non-resectable in the majority of patients often due to intrahepatic extension along bile duct branches/segments, and even after complete resection (R0) recurrence can be as high as 70%. Photodynamic therapy (PDT) is an established palliative local tumor ablative treatment for non-resectable hilar CC. We report the long-term outcome of curative resection (R0) pe...
Endoscopic biliary stenting is a well-established palliative procedure for treating obstructive jaundice in patients with unresectable hilar cholangiocarcinoma. Plastic tube stents (PS) have been widely used for the procedure, but self-expandable metallic stents (SEMSs) are becoming increasingly popular because of the associated longer patency. However, there are several unanswered questions re...
The biliary excretion of piperacillin has been assessed in 11 patients with obstructive jaundice due to hilar cholangiocarcinoma. After a 1-g intravenous dose administered 30 min before preliminary percutaneous transhepatic cholangiography, no drug was detected in the bile of seven patients; in four others, drug concentrations were far below the corresponding level in serum. After a period of e...
BACKGROUND The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) model, its Portsmouth (P-POSSUM) modification and the Estimation of physiologic ability and surgical stress (E-PASS) are three surgical risk scoring systems used extensively to predict postoperative morbidity and mortality in general surgery. The aim was to undertake the first study...
Endoscopic palliative biliary drainage is considered as a gold standard treatment in advanced or inoperable hilar cholangiocarcinoma. Also, metal stents are preferred over plastic stents in patients with >3 months life expectancy. However, the endoscopic intervention of advanced hilar obstruction is often more challenging and complex than that of distal malignant biliary obstructions. In this l...
BACKGROUND/AIM Major liver resection has improved the resectability rate of hilar cholangiocarcinomas, but morbidity and mortality may be significant. The aim of this study was to assess the value of parenchyma-conserving liver resection (resection of bile duct with liver segments I and IVb; PCLR) in hilar cholangiocarcinoma. METHODS Retrospective analysis of prospectively collected data. Fac...
Apart from periampullary carcinoma, the prognosis of biliary tract carcinomas, including hilar cholangiocarcinoma, extrahepatic biliary tract carcinoma, and gallbladder carcinoma, remains poor. Sophisticated diagnostic skills and treatment methods and their application are naturally required to achieve better treatment results for biliary tract carcinomas. However, it is not too much to say tha...
