Gastric cancer is one of the most common diseases globally. Total gastrectomy is often performed surgically. However, late-stage anastomotic passage obstruction after total gastrectomy is relatively rare.

Among the access methods used in SILS, the glove technique, which is typically similar to the multi-trocar approach, is simple, convenient, and inexpensive. However, given the absence of a fulcrum supporting the endoscopic surgical forceps, the technique is less advantageous than methods using commercially available access devices because of the poor maneuverability of the forceps.

An endotracheal tube with electromyography electrodes attached to it was recently developed for intraoperative neuromonitoring during thyroid surgery. Here we describe the successful identification and preservation of an extralaryngeal bifurcation of the recurrent laryngeal nerve by intraoperative neuromonitoring in a patient undergoing thyroid surgery.

Case Presentation: A 75-year-old Japanese (Asian) woman presented for further evaluation of a gallbladder polyp, 15 years after right radical nephrectomy for renal cell carcinoma.
A 66-year-old, right-handed male, was admitted to our hospital with difficulty in recognizing faces and colors. He had suffered a stroke in the right occipital region three years earlier that had induced left homonymous hemianopsia, but not prosopagnosia. A neurological examination revealed prosopagnosia, color agnosia, constructional apraxia, and topographical disorientation, but not either hemineglect or dressing apraxia.

We describe MR findings in older patients in whom white matter hyperintensities were attenuated by compression of the cerebral hemisphere from a chronic subdural hematoma. These sequential MR findings substantiate the hypothesis that leukoaraiosis may arise when drainage of the bulk flow of brain interstitial fluid is disturbed.

Laboratory examinations showed liver dysfunction and renal failure. The histological study showed dense lymphocytic and eosinophilic perivascular infiltrations in the upper dermis at the erythematous lesion.

Methods: Fifty-three consecutive patients underwent LINAC radiosurgery for VS between 1993 and 2002. Seven of these patients were lost to follow up.
Background/aims: Solitary small-sized HCCs tend to be considered as less aggressive cancer, and non-surgical treatments have recently been preferred. The aim of this study was to clarify the clinicopathological features and the prognostic factors of small-sized HCCs and to evaluate the significance of hepatic resection for them.
Methodology: Eighty patients with HCC up to 2cm in diameter who had undergone hepatic resection were enrolled in this study.
We clarified the indication of partial hepatectomy in hepatocellular carcinoma (HCC) patients with liver cirrhosis classified as Child-Pugh class B. Univariate analysis revealed that adverse prognostic factors were (1) the presence of ascites, (2) elevated total bilirubin (1.5 mg/dl or higher), (3) reduced choline esterase (160 IU/ or lower), (4) elevated alpha-fetoprotein (AFP) (400 ng/ml or higher), (5) microscopic vascular invasion, and (6) non-curative hepatectomy.

Methods: Surgical outcomes were reviewed in 136 cirrhotic patients with transplantable HCC who had undergone partial hepatectomy. Transplantable HCC was defined as that corresponding to Milan's criteria.
The pathway leading to cell death in clinical liver transplantation is not known. Eight liver transplant recipients and eight donors were enrolled in this study. Postoperative serum levels of alanine transferase had significantly increased in the recipients compared with those in the donors.

We demonstrated that liver NK cells have cytotoxicity against normal syngeneic hepatocytes in mice. Polyinosinic-polycytidylic acid (poly I:C) treatment enhanced hepatocyte toxicity of liver NK cells but not that of spleen NK cells.

Methods: Fifteen patients undergoing living-donor liver transplantation using a right lobe graft without the middle hepatic vein were enrolled in this study. During the course of harvesting and implantation, in vivo NIRS was performed on the liver grafts to determine hemoglobin (Hb) and cytochrome oxidase content in the hepatic tissues.
The purpose of this study was to investigate the usefulness of Fuji Computed Radiography (FCR) 5501D by comparing it with FCR 5000 and a screen-film system (S/F). Posteroanterior chest radiographs of ten patients with no abnormality on chest CT scans were obtained with FCR 5501D, FCR 5000, and S/F. Six observers (three radiologists and three radio-technologists) evaluated the visibility of nine normal anatomic structures (including lungs, soft tissue, and bones) and overall visibility on each image.

Although conservative methods using volume expansion with antithrombotic or anticoagulative agents are widely used for progressing stroke, in some hospitals, emergency carotid endarterectomy (CEA) has been performed for carotid stenosis, with mixed results. Here we report three cases with progressing ischemic stroke that were managed by endovascular surgical intervention.

The prognosis of patients with brain metastases is poor. Consequently, the purposes of treatment for such patients are also limited. One goal is to prevent the metastatic tumors from causing death, and another is to improve the neurological symptoms that are causing deterioration of the patient's quality of life.
