BACKGROUND/AIMS In treating many cases of postoperative adhesive small bowel obstruction (ASBO), we have found that if a long tube is not effective in conservative treatment, the surgical timing requires careful consideration. The aim of this study was to clarify the limits of conservative treatment, long tube management, and surgical timing. METHODOLOGY(More)
A 54-year-old male was admitted to our hospital for treatment of a liver tumor which was pointed out by screening ultrasonography. Computed tomography revealed a tumor in the right lobe of the liver measuring 7 cm in diameter. Angiography revealed a hypervascular tumor. A hepatocellular carcinoma or hypervascular metastatic tumor was suspected. A right(More)
Patients with hepatocellular carcinoma (HCC) show a wide variety of histologic changes in the noncancerous liver parenchyma, and these changes may affect the prognosis. In this study, we grouped patients according to the extent of liver impairment and investigated their long-term prognosis after hepatectomy for HCC. A total of 194 patients were divided into(More)
Epithelial cells of several types of hepatic cysts were examined by mucin histochemistry and immunohistochemically. There were some differences in mucus and antigenic expression among the hepatic cysts examined. Epithelial cells of non-parasitic simple cysts and adult-type polycystic liver showed similar mucin-histochemical and immunohistochemical features,(More)
We performed hepatic arterial infusion chemotherapy (HAI) on 86 patients with unresectable hepatocellular carcinoma (HCC, 61 patients) or unresectable recurrent HCC after hepatectomy (25 patients). As drug therapy, 250 mg of 5-fluorouracil was injected daily for 14 days using a reservoir embedded in the subcutaneous layer. During this period, 0.4 mg/kg of(More)
To improve the outcome of patients who had undergone hepatic resection for hepatocellular carcinoma (HCC), we employed postoperative adjuvant hepatic arterial infusion chemotherapy (AHAI) in 23 patients. Patients showing various risk factors for the recurrence of HCC were given one shot of doxorubicin and mitomycin C suspended in an oily medium (lipiodol)(More)
The aim of this study was to investigate whether different fabrication processes, such as the computer-aided design/computer-aided manufacturing (CAD/CAM) system or the manual build-up technique, affect the fracture resistance of composite resin-based crowns. Lava Ultimate (LU), Estenia C&B (EC&B), and lithium disilicate glass-ceramic IPS e.max press (EMP)(More)
Carcinomatous meningitis is clinically less common than brain metastasis or spinal cord compression, but has dire consequences for both the quality of life and the overall survival of patients with various kinds of malignancies. It occurs in about 5% of all adult cancer patients, though autopsies may double this number. The primary tumors that frequently(More)
The surfaces of hydroxyapatite-glass-titanium (HA-G-Ti) functionally gradient composite and titanium bars were treated with electrochemical apatite deposition, and a cathodic current was applied at 62 degrees C in a solution containing calcium and phosphate ions. Specimens with and without the electrochemical surface treatment were implanted in the femurs(More)
