[A case of hemosuccus pancreaticus caused by rupture of an aneurysm of the splenic artery].

Hemorrhage through the pancreatic duct into the duodenum, the so-called "hemosuccus pancreaticus", is a rare cause of gastrointestinal bleeding. A 75-year-old man, who was treated with anticoagulation agents for an old myocardial infarction, was admitted to our hospital for sudden tarry stools and abdominal pain. His hemoglobin level slightly dropped to 12.

[Computed tomography colonography for 5 cases of pneumatosis cystoides intestinalis].

Computed tomography colonography (CTC) was performed in 5 patients with pneumatosis cystoides intestinalis (PCI). The virtual colonoscopy view of CTC as well as total colonoscopy (TCS) findings showed polypoid lesions in the colon, and multiplanar reconstruction images of the colon revealed in the polypoid lesions of the colon. We confirmed the diagnosis of PCI in all cases.

Preliminary trial of rebamipide for prevention of low-dose aspirin-induced gastric injury in healthy subjects: a randomized, double-blind, placebo-controlled, cross-over study.

Although low-dose aspirin is widely used, since it is a cheap and effective means of prevention of cardiovascular events, it can cause hemorrhagic gastrointestinal complications. The aim of this study was to evaluate the efficacy of rebamipide in preventing low-dose aspirin-induced gastric injury. A randomized, double-blind, placebo-controlled, crossover trial was performed in twenty healthy volunteers.

A case report of the therapeutic effect of cryofiltration in a patient with glucocorticoid-resistant ulcerative colitis.

Ulcerative colitis (UC) is characterized by chronic inflammation of the colon and its cause and pathogenesis have not been fully clarified. Although UC is treated with various drugs, including 5-amino-salycilate and glucocorticoids, some patients are resistant to them. It was recently reported that apheresis, such as leukocytapheresis and granulocytapheresis, improves intestinal inflammation in refractory cases of UC.

Eradication of Helicobacter pylori for primary gastric cancer and secondary gastric cancer after endoscopic mucosal resection.

Because most gastric cancers develop from a background of Helicobacter pylori-infected gastric mucosa, H. pylori plays an important role in gastric carcinogenesis. Therefore, eradication of H.

Endoscopic submucosal dissection for treatment of early stage hypopharyngeal carcinoma.

Background: Early detection of hypopharyngeal carcinoma is increasingly possible and patients with such early lesions can be treated with endoscopic resection.

Objective: To identify the optimal relationship between the mucosal defect of the hypopharynx and malfunction of the hypopharynx after endoscopic resection of early hypopharyngeal carcinoma.

Design: Case series.

Histologic results of EMR for esophageal lesions diagnosed as high-grade intraepithelial squamous neoplasia by endoscopic biopsy.

Background: Biopsy specimens obtained from esophageal lesions detected in endoscopic screening with iodine staining have often been diagnosed as high-grade intraepithelial squamous neoplasia (WHO 2000). However, a management strategy for such lesions has not been established. The purpose of this study was to perform EMR for such lesions and to determine the actual tumor stage in patients with complete resection and the outcomes after EMR.

In vitro induction of resistance to metronidazole, and analysis of mutations in rdxA and frxA genes from Helicobacter pylori isolates.

In clinical Helicobacter pylori isolates, metronidazole resistance has been associated with mutations in the rdxA and frxA genes. The aim of this study was to examine the role of the rdxA and frxA genes after the in vitro induction of metronidazole resistance. A total of five suscep-tible H.

Endoscopic clip application for closure of esophageal perforations caused by EMR.

Background: With increasing use of EMR for early stage esophageal carcinoma, the number of cases of iatrogenic esophageal perforation is likely to increase. This study evaluated the results of endoscopic clip application for treatment of perforations caused by EMR in patients with esophageal carcinoma.

Methods: Among 185 patients who underwent EMR for esophageal carcinoma, esophageal perforation occurred in 3 patients (1.

EMR combined with chemoradiotherapy: a novel treatment for superficial esophageal squamous-cell carcinoma.

Background: Esophagectomy or chemoradiotherapy (CRT) are the procedures of choice for patients with superficial esophageal squamous-cell carcinoma. However, esophagectomy is highly invasive, and CRT is associated with the risk of local failure. A study was conducted of a novel treatment, EMR combined with CRT, for patients with superficial esophageal carcinoma.

Relationship between histopathologic gastritis and mucosal microvascularity: observations with magnifying endoscopy.

Background: The purpose of this study was to determine the usefulness of magnifying endoscopy for the diagnosis of Helicobacter pylori-induced histopathologic gastritis.

Methods: A total of 92 patients scheduled to undergo routine endoscopic examination were enrolled. After routine endoscopic examination, 3 sites in the stomach were studied by magnified observation.
