Indications for preoperative biliary drainage (PBD) in the context of hepatectomy for hilar malignancies are still debated. The aim of this study was to investigate current European practice regarding biliary drainage before hepatectomy for Klatskin tumours.
This was a retrospective analysis of all patients who underwent formal or extended right or left hepatectomy for hilar cholangiocarcinoma between 1997 and 2008 at 11 European teaching hospitals, and for whom details of serum bilirubin levels at admission and at the time of surgery were available. PBD was performed at the physicians' discretion. The primary outcome was 90-day mortality. Secondary outcomes were morbidity and cause of death. The association of PBD and of preoperative serum bilirubin levels with postoperative mortality was assessed by logistic regression, in the entire population as well as separately in the right- and left-sided hepatectomy groups, and was adjusted for confounding factors.
A total of 366 patients were enrolled; PBD was performed in 180 patients. The overall mortality rate was 10·7 per cent and was higher after right- than left-sided hepatectomy (14·7 versus 6·6 per cent; adjusted odds ratio (OR) 3·16, 95 per cent confidence interval 1·50 to 6·65; P = 0·001). PBD did not affect overall postoperative mortality, but was associated with a decreased mortality rate after right hepatectomy (adjusted OR 0·29, 0·11 to 0·77; P = 0·013) and an increased mortality rate after left hepatectomy (adjusted OR 4·06, 1·01 to 16·30; P = 0·035). A preoperative serum bilirubin level greater than 50 µmol/l was also associated with increased mortality, but only after right hepatectomy (adjusted OR 7·02, 1·73 to 28·52; P = 0·002).
PBD does not affect overall mortality in jaundiced patients with hilar cholangiocarcinoma, but there may be a difference between patients undergoing right-sided versus left-sided hepatectomy.

- "Percutaneous drainage has been recommended in a recent study for PBD (27). PBD showed no effect on the mortality rate in jaundiced patients with hilar cholangiocarcinoma (28). In the present study, a markedly increased survival time was observed in patients having received surgery following biliary drainage. "

ABSTRACT: The present study aimed to investigate the clinical outcomes of percutaneous transhepatic biliary drainage in patients with obstructive jaundice and identify potential predictors of patient survival. Clinical data from 102 patients (66 males and 36 females; median age, 63.50 years; range, 29-84 years) with a mean (± standard deviation) pre-drainage serum bilirubin level of 285.4 (±136.7 μmol/l), were retrospectively studied. Technical and clinical success, complications and survival time were recorded and their relationship with clinical factors, including age, obstruction level, liver metastases, serum bilirubin level and subsequent treatments following drainage, were analyzed by Fisher's exact test. Patient survival rate and other predictors were analyzed by Kaplan-Meier survival curves and Cox's proportional hazard model. The technical and clinical success rates were 100 and 76.5%, respectively. The presence of liver metastases was associated with reduced successful drainage. The overall complication rate was 7.8% and the overall median survival time was 185 days [95% confidence interval (CI), 159-211 days]. A log-rank test showed that age (χ(2), 4.003; P=0.04), bilirubin levels following procedure (χ(2), 5.139; P=0.02) and subsequent therapy (χ(2), 15.459; P=0.00) affected survival time. However, Cox's regression analysis revealed no administration of additional treatments to be a risk factor of survival (odds ratio, 2.323; 95% CI, 1.465-3.685; P=0.000). Percutaneous transhepatic biliary drainage for malignant biliary obstruction was found to be a safe and effective method to relieve jaundice caused by progressive neoplasms. Subsequent radical therapy following drainage, including surgery, chemotherapy and other local treatment types, are likely to increase patient survival.

ABSTRACT: Cholangiocarcinomas (CCAs) are rare malignancies that originate from the epithelial cells of the bile ducts. It is the second most-common primary liver cancer after hepatocellular carcinoma. Recent epidemiologic studies have shown that the overall incidence and mortality rates of CCAs are increasing. Diagnosis is often challenging due to the difficulty in getting tissue/cytology for confirmation, and it comprises a combination of cross-imaging, tumor markers, histology, and cholangiography. Surgery involving major resections of liver, bile duct, pancreas, and at times adjacent vessels is the only chance for cure. Evaluation should be focused on the assessment of tumor resectability, hepatic reserve, and patient physiological fitness for major surgery. In patients not fit for major surgery, biliary drainage for jaundice is an appropriate intervention and if there is histologic confirmation of a CCA, palliative therapies focused on local and systemic disease control should be considered. The endeavor to expand the indications for liver transplantation reflects the efforts to provide an effective form of therapy for a previously untreatable disease. A multidisciplinary specialized approach should be the platform for providing the best comprehensive care for these patients.

ABSTRACT: To assess the outcomes of patients with hilar cholangiocarcinoma following referral to a specialist multi-disciplinary team.
Over an 11-year period, patients referred with hilar cholangiocarcinoma were identified from a prospectively maintained registry. Collated data included demographics, operative findings and histo-pathological data. Survival differences and prognostic factors were determined.
345 patients were referred with hilar cholangiocarcinoma, of which 57 (16.5%) patients had surgery. Prior to 2008, of 143 patients referred, only 17 (11.9%) patients underwent surgery, compared to 40 (19.8%) of 202 patients referred from 2008 onwards (p = 0.051). In the surgery group, the majority of patients underwent left hemi-hepatectomy (n = 19). In addition, portal vein (n = 5), hepatic artery (n = 2) and inferior vena cava (n = 3) resections were performed. The R0 resection rate was 73.7%. The morbidity and mortality rates were 59.6% and 14.0%, respectively. The median disease-free survival was 16 (4-101) months. The presence of lymph node metastasis (p = 0.002) was the only predictor of poorer disease-free survival. The 5-year overall survival was 39.5% and was significantly better than that of the palliative group (p < 0.001).
Surgery is the optimal treatment option for patients with hilar cholangiocarcinoma and is associated with better overall survival. Prompt referral to tertiary centres with a core team of clinicians to manage this difficult condition may allow more patients to come to potentially curative surgical resections.
