Icteric type hepatocellular carcinoma is rare, and a poor prognosis has been demonstrated in the past. We performed this study to re-evaluate prognosis since the availability of modern diagnostic modalities. Of 3921 patients with hepatocellular carcinoma in our hospital, 9 patients who presented with tumor fragments in common bile duct and had a pa...

We report a patient, a 23-year-old man, who had clinical and laboratory findings suggestive of insulinoma. Although imaging studies did not reveal any tumors in the pancreas, distal pancreatectomy was performed because the possibility of small insulinoma could not be completely excluded. Grossly, the surgically removed pancreas did not reveal any t...

The reestablishment of anal function by transposition of the gracilis muscle, combined with the implantation of electrodes and a neuromuscular stimulator (dynamic graciloplasty), has recently been developed. With this method, the transposed muscle maintains contraction by electrical stimulation to maintain neoanal pressure without fatigue. It is ne...

Focal nodular hyperplasia (FNH) is a benign lesion of the liver which usually presents with one or two localizations. We report a patient with history of resection of a biliary cyst, and who had been taking oral contraceptives for the past 18 years, who had multiple localizations of FNH (more than 30 lesions). The largest lesion measured 10.5 × 11 ...

Sequence variation in the putative nonstructural region 5b (NS5b) of hepatitis C virus (HCV) was analyzed in China. Complementary DNA fragments from sera of 49 Chinese patients were amplified by polymerase chain reaction (PCR) and the products were cloned and sequenced. Based on the comparison in NS5b of 33 clones of genotype 1b and 16 clones of ge...

In recent years Helicobacter pylori infection has been implicated in the etiology of a variety of upper gastrointestinal diseases. The aim of this multi-center trial was to search for the cut-off value of the simple 13C-urea breath test (13C-UBT) for diagnosis of H. pylori infection, and to examine the sensitivity and specificity of 13C-UBT for cul...

To investigate the prevalence of hepatitis G virus (HGV/GBV-C) in patients with liver disease and to confirm its hypothesized ability to cause liver damage, we studied 130 subjects; 61 had chronic hepatitis C virus infection and 69 had acute hepatitis of either defined etiology (n = 57) or of unknown origin (n = 12). Positivity for HGV/GBV-C RNA wa...

We report a rare case of multiple gastric plasmacytomatous lesions at an early stage found incidentally in a stomach resected because of gastric cancer. The three lesions had different macroscopic features, showing depressed, submucosal, and nodular tumor-forming types. The smallest, a depressed lesion, produced IgG of the λ and ϰ types, and had a ...

In a 68-year-old Japanese man, a gastric polyp 24 mm in diameter with a stalk 15 mm in diameter was diagnosed as well differentiated adenocarcinoma and treated by endoscopic polypectomy. Histologically, most of the resected tissue was adenoma, and atypical cells were papillarily proliferating to form adenocarcinoma in adenoma, a Nakamura type IV ga...

Endoscopic variceal ligation therapy (EVL) seems to be a more effective and safer method than endoscopic injection variceal sclerotherapy (EVS) for treating bleeding esophageal varices. However, EVL may entail a higher recurrence rate than EVS. The aim of this study was to examine whether EVL combined with low-dose EVS reduced the recurrence rate c...
