OBJECTIVE: To propose an algorithm for resecting hepatocellular carcinoma (HCC) in the caudate lobe. BACKGROUND: Owing to a deep location, resection of HCC originating in the caudate lobe is challenging, but a plausible guideline enabling safe, curable resection remains unknown. METHODS: We developed an algorithm based on sublocation or size of the tumor and liver function to guide the optimal procedure for resecting HCC in the caudate lobe, consisting of 3 portions (Spiegel, process, and caval)...

BACKGROUND: The impact of a wide surgical margin on the outcome of patients with hepatocellular carcinoma (HCC) has not been evaluated in relation to the type of liver resection performed, anatomical or non-anatomical. The aim of this study was to evaluate the impact of surgical margin status on outcomes in patients undergoing anatomical or non-anatomical resection for solitary HCC. METHODS: Data from patients with solitary HCC who had undergone non-anatomical partial resection (Hr0 group) or an...

Abstract Background Resection of hepatocellular carcinoma located in the caudate lobe is challenging because this anatomical location is difficult to approach, especially the caval portion. Methods We performed resection of the caval portion of the caudate lobe using a ventral approach combined with the resection of segment IV, VII, or VIII for hepatocellular carcinoma in 41 patients (extended segmentectomy group). As a control group, 138 patients with hepatocellular carcinoma who underwent segm...

The definition and extent of the human caudate lobe in the liver is unclear, and thus, the anatomy of the caudate lobe was studied using 23 corrosion liver casts, with special reference to the portal venous and biliary branches. These branches and their ramification type in the caudate lobe showed that this lobe includes: (1) the Spiegel lobe; (2) the paracaval portion; and (3) the caudate process portion. The three portions often have their own independent branches; for example, the portal veno...

Background Isolated anatomic total caudate lobectomy is indicated in patients who have liver tumors limited to the caudate lobe. However, isolated caudate lobe resection is a challenging surgical procedure that required safe and reliable techniques. All portal and hepatic veins that connect this area originate from the first branch of the portal vein or vena cava; therefore, the operator must be cautious of the potential for massive bleeding.

The 19th Nationwide Follow-up Survey of Primary Liver Cancer in Japan comprised 20 850 primary liver cancer patients newly registered at 482 medical institutions over a period of 2 years (from 1 January 2006 to 31 December 2007). Of these, 94.7% had hepatocellular carcinoma (HCC) and 4.4% had intrahepatic cholangiocarcinoma (ICC). In addition, follow-up data were obtained regarding 34 752 patients who were registered in the previous survey. Epidemiological and clinicopathological factors, diagno...

AIM: To investigate the significance of the surgical approaches in the prognosis of hepatocellular carcinoma (HCC) located in the caudate lobe with a multivariate regression analysis using a Cox proportional hazard model. METHODS: Thirty-six patients with HCC underwent caudate lobectomy at a single tertiary referral center between January 1995 and June 2010. In this series, left-sided, right-sided and bilateral approaches were used. The outcomes of patients who underwent isolated caudate lobecto...

Background The caudate lobe of the liver is located behind both major lobes and is surrounded by the inferior vena cava, three main hepatic veins, and the hepatic hilum. Despite a hard-to-approach anatomic location, isolated complete removal of the caudate lobe is recommended to improve curability in hepatocellular carcinoma (HCC). This is because most patients with HCC cannot undergo caudate lobectomy (segmentectomy 1) with resection of adjacent liver regions due to their poor liver function.

Abstract Background Hepatocellular carcinoma (HCC) originating in the caudate lobe is rare, and the treatment for this type of carcinoma is difficult because of its unique anatomic location. Methods This retrospective study assessed the surgical outcome of patients with caudate lobe HCC. There were 20 cases of HCC originating in the caudate lobe among 435 patients with primary HCC who underwent hepatic resection in our department from 1990 to 2002. The caudate tumors were located in the Spiegel ...

Background/Aims: Resection of the caudate lobe of the liver is difficult to perform because ofa deep location and an adjacency to the major vessels. Methodology: A total of 30 patients with hepatocellular carcinoma (HCC) originating in the caudate lobe underwent hepatic resection. The lobe was classified to Spiegel's portion, the process portion, and the caval portion. The operative procedure undertaken was chosen on the basis of tumor location as well as hepatic function of each patient. Result...
