Although hepatitis C virus (HCV)-related cirrhosis has been suggested as a risk factor for intrahepatic cholangiocarcinoma (ICC), few sizeable studies have tested this hypothesis. We investigated ICC risk factors, with special reference to HCV infection. We conducted a hospital-based case-control study including 50 ICC patients and 205 other surgical(More)
BACKGROUND Bile leakage is one of the frequent and disturbing complications of hepatic resection. STUDY DESIGN Clinical records of the 363 patients who underwent hepatic resections without biliary reconstruction for hepatic cancers between January 1994 and June 2001 were reviewed. Postoperative bile leakage was defined as continuous drainage with a(More)
Clinicopathologic features and postoperative outcomes were investigated for patients who underwent curative surgery for biliary marker (CK7 and CK19)-positive hepatocellular carcinoma (HCC). Of 157 HCCs, 93 were CK7(-)CK19(-), 49 were CK7(+)-CK19(-), 1 was CK7(-)CK19(+), and 14 were CK7(+)- CK19(+). Semiquantitative analysis of expression levels(More)
BACKGROUND The prognosis for patients with intrahepatic cholangiocarcinoma differs according to macroscopic type. The identification of clinical and pathological features that predict outcome in patients with mass-forming intrahepatic cholangiocarcinoma is required in order to determine optimal surgical strategies for patients with this type of tumour.

BACKGROUND/PURPOSE The postoperative outcome of patients who have intrahepatic cholangiocarcinoma with lymph node metastases is extremely poor, and the indications for surgery for such patients have yet to be clearly established. METHODS The demographic and clinical characteristics of 133 patients who underwent lymph node dissection during hepatic(More)
Malnutrition has been considered a risk factor for the development of a surgical site infection (SSI). The aim of this study was to determine the relationship between preoperative nutritional screening scores and the development of SSI after pancreaticoduodenectomy. We examined 64 patients who had undergone pancreaticoduodenectomy. Their clinical data,(More)
A high serum cytokeratin 19 fragment (CYFRA21-1) concentration in patients with various cancers is associated with poor prognosis. This study aimed to establish the clinical significance of preoperative serum CYFRA21-1 in patients with intrahepatic cholangiocarcinoma. CYFRA21-1, carcinoembryonic antigen (CEA), and carbohydrate antigen (CA) 19-9(More)
Background. The clinicopathologic features of cystic neoplasms of the liver, such as cystadenoma and cystadenocarcinoma, are poorly defined because these lesions are extremely rare. Methods. Clinicopathologic findings in six patients who underwent surgery for a cystic hepatic neoplasm were reviewed retrospectively to determine the best surgical strategy to(More)
BACKGROUND Hepatic resection is main approach to treatment of hepatolithiasis, but the long-term follow-up results of hepatic resection for hepatolithiasis are rarely reported. METHODS A retrospective study was conducted of 87 patients with hepatolithiasis who underwent hepatic resection. RESULTS The final stone clearance rates were 95%. There was a(More)
BACKGROUND/PURPOSE The aim of this study was to clarify the prognostic factors of intrahepatic cholangiocarcinoma (ICC) following hepatectomy and to examine the impact of lymph node metastasis on survival. This study was therefore carried out as a Project Study of the Japanese Society of Hepato-Biliary-Pancreatic Surgery. METHODS Three hundred and(More)
