This article describes the surgical techniques and indications of laparoscopic partial hepatectomy, which is not as widely available as laparoscopic cholecystectomy. Three patients with hepatocellular carcinoma and associated severe liver cirrhosis were candidates for this technique from July 1993 to August 1994. The tumor size was 4 cm or less and all the(More)
We compared liver volume and function kinetics after partial hepatectomy according to extent of resection and severity of coexisting liver disease in 57 adults with uneventful postoperative courses. Liver volume and massiveness of resection, or resection rate, were estimated on computed tomography. Patients were categorized into three groups on the basis of(More)
BACKGROUND This study investigated the relationship between clinicopathologic features and various viral serologies in patients who underwent hepatectomy in the treatment of hepatocellular carcinoma (HCC). METHODS Two hundred two patients were allocated to four groups, according to their positivity or negativity for hepatitis B surface antigen (HBsAg) and(More)
BACKGROUND The mode of tumor growth of intrahepatic cholangiocarcinoma (CC) varies considerably from patient to patient. This study describes the clinicopathologic variety of the extraductal mass-forming type of CC. METHODS Patients with CC characterized by an extraductal mass (n = 26) who underwent hepatectomy from 1976 through 1992 were(More)
Hyphal cells of Candida albicans bound to human hemoglobin, but not the yeast cells. The amount of hemoglobin receptor was significantly higher on the hyphal cells than on the yeast cells. Only the hyphal cells of C. albicans used hemoglobin as a source of iron. The hemolytic factor was detected in the culture supernatant of the hyphal cell of C. albicans.
Immunohistochemical staining for proliferating cell nuclear antigen (PCNA) and cathepsin D was performed on 60 transitional cell carcinoma (TCC) specimens from 60 patients with bladder cancer. The percentage of PCNA-positive cells (PCNA-labelling index) was determined by counting 500 or 1,000 cells, and cathepsin D expression was graded according to the(More)
This study was designed to investigate whether or not a novel nonselective endothelin A/B (ETA/ETB) receptor antagonist (TAK-044) provides hepatoprotection during porcine liver transplantation. The grafts were stored in chilled Euro-Collins solution and recirculated following reflush with lactated Ringer's with (TAK group) or without (control group) TAK-044(More)
BACKGROUND A safe limit for normothermic consecutive portal triad occlusion in hepatectomy for the cirrhotic liver was believed to be around 30 minutes. Possibly, the occlusion time can be prolonged by cooling the ischemic liver in vivo. We describe the technique of segmentectomy assisted by topical cooling and its usefulness in prolonging the hepatic(More)
BACKGROUND Chronic obstructive pulmonary disease is caused mainly by habitual smoking and is common among elderly individuals. It involves not only airflow limitation but also metabolic disorders, leading to increased cardiovascular morbidity and mortality. OBJECTIVE We evaluated relationships among smoking habits, airflow limitation, and metabolic(More)
INTRODUCTION The value of measuring procalcitonin (PCT) in patients with community-acquired pneumonia (CAP) is unclear. The aim of this study was to determine the value of PCT as a marker for microbial etiology and a predictor of outcome in CAP patients. METHODS A single-center observational study was conducted with CAP patients. On admission, their(More)
