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)...

The surgical indications for liver metastasis from bile duct cancer remain contentious, because surgery is generally thought unlikely to improve survival. However, recent reports show that long-term survival has been achieved with liver resection of metastasis from recurrent bile duct cancer in selected patients. Liver resection for liver metastasis from bile duct cancer was proposed only when the following criteria were met: liver-only metastasis, a solitary tumor, and no increase in the number...

BACKGROUND Surgical treatment for hepatocellular carcinoma (HCC) is advancing, but a robust prediction model for survival after resection is not available. The aim of this study was to propose a prognostic grading system for resection of HCC. METHODS This was a retrospective, multicentre study of patients who underwent first resection of HCC with curative intent between 2000 and 2007. Patients were divided randomly by a cross-validation method into training and validation sets. Prognostic factor...

Abstract Background Liver stiffness measurement using magnetic resonance elastography can assess the severity of liver fibrosis, which is significantly associated with recurrence after curative resection for hepatocellular carcinoma. The aim of this prospective study was to investigate whether preoperative liver stiffness measurement by magnetic resonance elastograhy can predict recurrence after curative resection for hepatocellular carcinoma. Methods Patients who underwent preoperative liver st...

AIM Hepatocellular adenoma (HCA) has a lower prevalence in Japan than in Western countries and HCA subtypes have been reported for only a few Japanese patients. We analyzed HCA subtype data 38 patients from 23 hospitals in Japan in order to examine character and difference between Western countries. METHODS To confirm HCA and to analyze subtypes, we performed immunohistochemical examinations. RESULTS Thirty-eight cases were found to have HCA without cirrhosis. The male/female ratio was 18/20. Ag...

BACKGROUND Subcuticular sutures reduce wound complication rates only in clean surgeries. Repeat resection is frequently required in liver surgery, due to the high recurrence rate (30-50%) of liver cancers. The aim of this study is to assess that subcuticular sutures is superior to staples in liver surgery. METHODS This single-centre, single-blinded, randomised controlled trial was conducted at a university hospital between January 2015 and October 2018. Patients were randomly assigned (1:1) to r...

Liver cancer frequently requires repeated liver resections due to the high recurrence rate. The aim of this study was to clarify whether subcuticular sutures reduce wound complication rates following repeat incisions. Data from 382 repeated liver resections in 1,245 consecutive patients were assessed. Patients were divided into a Subcuticular sutures group and a Skin staples group on the basis of the wound-closure method. To avoid bias in analysing wound complications, data were matched to adjus...
