Project description:ObjectiveTo report our experience in the surgical management of hilar cholangiocarcinoma in a nontransplant center.MethodsWe reviewed the medical charts of patients who underwent surgical resection of hilar cholangiocarcinoma from 1996 to 2016. The preoperative workup as well as the operative techniques were presented. The postoperative mortality and morbidity were detailed with particular emphasis on long survivals.ResultsForty patients met our inclusion criteria,22 patients (55%) had surgical resection with curative intent. Thirty-day postoperative mortality occurred in three cases (13.6%), four patients had grade II, III Clavien-Dindo complications and only one required re-laparotomy (18%).The median follow up duration was 43.4 months.ConclusionHilar cholangiocarcinoma is a rare disease with complete surgical resection presenting the best chance of cure. In addition to the free resection margins, lymph node involvement and the histological type are the most significant factors of prognosis. Histologic type such as primary lymphoma and papillary carcinoma are associated with better survival outcomes. Portal vein embolization should be considered if extended right hepatectomy is contemplated.

Project description:Laparoscopic resection of hilar cholangiocarcinoma is technically challenging because it involves complicated laparoscopic procedures that include laparoscopic hepatoduodenal lymphadenectomy, hemihepatectomy with caudate lobectomy, and hepaticojejunostomy. There are currently very few reports describing this type of surgery. Between August 2014 and December 2014, 5 patients underwent total laparoscopic or laparoscopic-assisted surgery for hilar cholangiocarcinoma. Two patients with type I or II hilar cholangiocarcinoma underwent radical hilar resection. Three patients with type IIIa or IIIb cholangiocarcinoma underwent extended hemihepatectomy together with caudate lobectomy. The median (range) age, operation time, blood loss, and length of hospital stay were 63 years (43-76 years), 610 minutes (410-665 minutes), 650 mL (450-1,300 mL), and 12 days (9-21 days), respectively. Four patients had a negative margin, but 1 patient was diagnosed with high-grade dysplasia on the proximal resection margin. The median tumor size was 3.0 cm. One patient experienced postoperative biliary leakage, which resolved spontaneously. Laparoscopic resection is a feasible surgical approach in selected patients with hilar cholangiocarcinoma.

Project description:Cancer arising from the proximal biliary tree, or hilar cholangiocarcinoma, remains a difficult clinical problem. Significant experience with these uncommon tumors has been limited to a small number of centers, which has greatly hindered progress. Complete resection of hilar cholangiocarcinoma is the most effective and only potentially curative therapy, and it now clear that concomitant hepatic resection is required in most cases. Simply stated, long-term survival is generally possible only with an en bloc resection of the liver with the extrahepatic biliary apparatus, leaving behind a well perfused liver remnant with adequate biliary-enteric drainage. Preoperative imaging studies should aim to assess this possibility and must evaluate a number of tumor-related factors that influence resectability. Advances in imaging technology have improved patient selection, but a large proportion of patients are found to have unresectable disease only at the time of exploration. Staging laparoscopy and (13)fluoro-deoxyglucose positron emission tomography (FDG-PET) may help to identify some patients with advanced disease; however, local tumor extent, an equally critical determinant of resectability, may be underestimated on preoperative studies. This paper reviews issues pertaining to diagnosis and preoperative evaluation of patients with hilar biliary obstruction. Knowledge of the imaging features of hilar tumors, particularly as they pertain to resectability, is of obvious importance for clinicians managing these patients.

Project description:Cancer of the biliary confluence also known as hilar cholangiocarcinoma (HC) or Klatskin tumor, is a rare type of neoplastic disease constituting approximately 40%-60% of intrahepatic malignancies, and 2% of all cancers. The prognosis is extremely poor and the majority of Klatskin tumors are deemed unresectable upon diagnosis. Most patients with unresectable bile duct cancer die within the first year after diagnosis, due to hepatic failure, and/or infectious complications secondary to biliary obstruction. Curative treatments include surgical resection and liver transplantation in highly selected patients. Nevertheless, very few patients are eligible for surgery or transplant at the time of diagnosis. For patients with unresectable HC, radiotherapy, chemotherapy, photodynamic therapy, and liver-directed minimally invasive procedures such as percutaneous image-guided ablation and intra-arterial chemoembolization are recommended treatment options. This review focuses on currently available treatment options for unresectable HC and discusses future perspectives that could optimize outcomes.

Project description:The majority of patients who present with hilar cholangiocarcinoma will have incurable disease and require only palliation. Efficient relief of disabling symptoms is required with minimal morbidity and mortality and can be achieved by either surgical or non-operative options. A review of the indications, anatomical considerations and surgical techniques is presented. Segment III cholangio-jejunostomy is the most frequently used surgical bypass procedure and in those patients with an expected survival of more than 6 months, surgical palliation offers good quality and long-lasting palliation. There is a need for randomized controlled data to define the optimal role of surgical palliation in this difficult disease.

Project description:Surgery is the only curative therapy for patients with hilar cholangiocarcinoma (HCCA). Combined portal vein resection (PVR) could achieve negative resection margins in HCCA patients with portal vein invasion. This systematic review aimed to analysis the efficiency of combined PVR for HCCA.MEDLINE, EMBASE, the Cochrane Library, the Chinese National Knowledge Infrastructure database, and clinical trial registries were searched through April 2015. Risk ratios (RRs), and 95% confidence intervals (CIs) were calculated.The analysis included 21 retrospective studies, altogether involving 2403 patients (patients with PVR, n=637; patients without PVR, n=1766). Patients with PVR were likely to have more advanced HCCA (lymphatic invasion: RR=1.14, 95% CI 1.02 to 1.28; perineural invasion: RR=1.31, 95% CI 1.05 to 1.63) and suffered less curative resections (RR=0.89, 95% CI 0.75 to 0.99). Postoperative morbidity was similar between patients with or without PVR (RR=1.06, 95% CI 0.94 to 1.02). Patients with PVR suffered higher mortality rate (RR=1.52, 95% CI 1.06 to 2.18), and worse 5-year survival rate (RR=0.67, 95% CI 0.49 to 0.91).Combined PVR for HCCA patients would not increase postoperative morbidity rate. However, ascribed to PVR group concluded more advanced HCCA patients; patients with PVR had increased postoperative mortality rate and worse survival rate. The results still need further high quality trails for validation.

Project description:This article reviews the preoperative evaluation and operative considerations in patients with hilar cholangiocarcinoma. The preoperative evaluation is based on the imaging evaluation of the longitudinal and radial extent of the tumour along and around the hepatic duct confluence. The use of portal vein embolization to increase the safety of extended hepatectomy and the extent of surgical resection (caudate lobe and portal vein) are discussed within the context of recently published series.

Project description:Of 400 patients with hilar cholangiocarcinoma who were treated at Nagoya University Hospital from 1977 to 2004, 301 (75%) underwent surgical resection. Most patients underwent major hepatectomy with extrahepatic bile duct resection. The overall mortality rate was 7.6% but had decreased to 2.5% in the last 5 years (p=0.007). The overall survival rates at 5, 10 and 15 years were 22%, 13% and 10%, respectively. The survival rates of 233 patients undergoing R0 resection were 27%, 16% and 13%, respectively. R1 or R2 resection, lymph node metastasis and portal vein involvement were significant negative prognostic factors, although survival was better than in patients with unresected tumours. The results show that aggressive surgical treatment of hilar cholangiocarcinoma offers good outcomes with an acceptable mortality rate.

Project description:BACKGROUND: Hilar cholangiocarcinoma is a rare tumour which is best managed by an aggressive surgical approach. The role of adjuvant or neoadjuvant radiation therapy, chemotherapy or chemoradiation remains controversial, as no prospective randomized studies have been performed. METHODS: This review summarizes the recent literature regarding the role of radiation, chemotherapy and chemoradiation in hilar cholangiocarcinoma. The results of a biliary cancer questionnaire regarding current treatment strategies are also reported. RESULTS: A number of retrospective studies have shown that patients treated with adjuvant radiation therapy have prolonged survival compared with untreated patients. However, most of these reports did not control for tumour stage or performance status. A carefully controlled trial from the Johns Hopkins Hospital did not demonstrate any benefit for adjuvant radiation therapy. A number of phase II trials of chemotherapy have demonstrated modest response rates (20-40%). The best responses have been reported with 5-fluorouracil (5-FU) in combination with interferon-alpha or with leucovorin and mitomycin C. Recent non-randomized reports of chemoradiation with 5-FU with or without gemcitabine as the radiosensitizer suggest, but do not prove, improved survival. Adjuvant chemoradiation is currently being employed at specialized centres most often in the Americas (71%) and the Asia/Pacific region (55%) and to a lesser degree in Europe (29%). DISCUSSION: The only chance for long-term survival in patients with hilar cholangiocarcinoma is complete resection with negative margins. Neither radiation therapy nor chemotherapy alone has been proven to prolong survival in completely or partially resected patients or in unresected patients. Recent uncontrolled data suggest that chemoradiation may improve survival in resected and locally unresectable patients. However, prospective, randomized multicentre trials need to be performed to confirm efficacy.
