ABSTRACT We conducted this study to assess the safety of performing right trisectionectomy with caudate lobectomy for hilar cholangiocarcinoma by analyzing postoperative mortality and morbidity, and to evaluate the effect of such procedure on pathological curability and long-term overall survival.
A retrospective clinicopathological analysis was performed for 16 hilar cholangiocarcinoma patients who underwent right trisectionectomy with caudate lobectomy from June 1999 to April 2003. The median follow-up period was 36.9 months. The preoperative Bismuth-Corlette type was type II in four patients, type III(A) in 10 patients, and type IV in two patients.
The median liver volume after hepatic resection was 21.9% of the total liver volume. Postoperative complications including one chronic liver failure developed in 12 patients, but no in-hospital deaths occurred. A postoperative pathological examination showed a cancer free margin in all of the proximal resection sites, although three cases had carcinoma in situ (CIS) lesions in the distal margin that were confirmed during surgery. The 1-, 3-, and 5-year overall survival rates were 94.1%, 64.2%, and 64.2%, respectively.
We obtained excellent survival rates without any in-hospital deaths following right trisectionectomy with caudate lobectomy. This procedure may be an effective surgical procedure that can be executed to achieve low mortality rate and high pathological curability for hilar cholangiocarcinomas, except for Bismuth type III(B).

    ABSTRACT: Background Hilar cholangiocarcinoma is the most common malignant tumor affecting the extrahepatic bile duct. Surgical treatment offers the only possibility of cure, and it requires removal of all tumoral tissues with adequate resection margins. The aims of this review are to summarize the findings and to discuss the controversies on the extent of surgical resection aiming at cure for hilar cholangiocarcinoma. Methods The English medical literatures on hilar cholangiocarcinoma were studied to review on the relevance of adequate resection margins, routine caudate lobe resection, extent of liver resection, and combined vascular resection on perioperative and long-term survival outcomes of patients with resectable hilar cholangiocarcinoma. Results Complete resection of tumor represents the most important prognostic factor of long-term survival for hilar cholangiocarcinoma. The primary aim of surgery is to achieve R0 resection. When R1 resection is shown intraoperatively, further resection is recommended. Combined hepatic resection is now generally accepted as a standard procedure even for Bismuth type I/II tumors. Routine caudate lobe resection is also advocated for cure. The extent of hepatic resection remains controversial. Most surgeons recommend major hepatic resection. However, minor hepatic resection has also been advocated in most patients. The decision to carry out right- or left-sided hepatectomy is made according to the predominant site of the lesion. Portal vein resection should be considered when its involvement by tumor is suspected. Conclusion The curative treatment of hilar cholangiocarcinoma remains challenging. Advances in hepatobiliary techniques have improved the perioperative and long-term survival outcomes of this tumor.

    ABSTRACT: A right and left hepatic trisectionectomy and an extended trisectionectomy are the largest liver resections performed for malignancy. This report analyses a series of 23 patients who had at least one repeat resection after a hepatic trisectionectomy for colorectal liver metastasis (CRLM). A retrospective analysis of a single-centre prospective liver resection database from May 1996 to April 2009 was used for patient identification. Full notes, radiology and patient reviews were analysed for a variety of factors with respect to survival. Twenty-three patients underwent up to 3 repeat hepatic resections after 20 right and 3 left hepatic trisectionectomies. In 18 patients the initial surgery was an extended trisectionectomy. Overall 1-, 3- and 5-year survival rates after a repeat resection were 100%, 46% and 32%, respectively. No factors predictive for survival were identified. A repeat resection after a hepatic trisectionectomy for CRLM can offer extended survival and should be considered where appropriate.

    ABSTRACT: PurposeExtended liver resection may provide long-term survival in selected patients with Bismuth type IV hilar cholangiocarcinoma (HCCA). The purpose of this study was to identify anatomical factors that predict curative-intended resection.MethodsThirty-three of 159 patients with Bismuth type IV HCCA underwent major hepato-biliary resection with curative intent (CIR) between 2000 and 2010. Disease extent and anatomical variations were analyzed as factors enabling CIR.ResultsCIR ratio with hilar trifurcation bile duct variation (13/16) was significantly higher than that with other bile duct variation types (18/25). Hilum to left second bile duct confluence and tumor infiltration over left second bile duct confluence lengths in right-sided CIR were significantly shorter than those lengths in left-sided CIR (10.8 ± 4.9 and 2.7 ± 0.8 mm vs. 16.5 ± 8.4 and 7.0 ± 5.3 mm, respectively). Left-sided CIR patients had a marginally higher proportion of tumors invading ≤5 mm over the right second confluence than that in right-sided CIR patients (13/17 vs. 6/16; P = 0.061). The 3-year survival rate after CIR (28%) was significantly higher than after non-CIR (6.1%).ConclusionWe recommend the criteria of CIR as bile duct variation type, length of hilum to contralateral second bile duct confluence, and extent of tumor infiltration over the second confluence for Bismuth type IV HCCA.
