BACKGROUND The aim of the present study was to examine the safety and efficacy of endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) based on the long-term outcomes. PATIENTS AND METHODS From June 2002 to March 2007, ESD was carried out in 472 cases and 570 lesions of EGC. Post-surgical cases and status-unknown cases were excluded. The(More)
Two cases of multiple carcinoid tumors of the rectum with numerous micronests of carcinoid tumors are reported. The patients were 51- and 58-year-old males. Many carcinoid tumors and numerous carcinoid micronests were found in the resected rectum; the total number of carcinoid tumors, groups of micronests, and solitary micronests was 69 in the first case(More)
We examined the characteristics of upper gastrointestinal disorders induced by non-steroidal anti-inflammatory drugs (NSAIDs). The questionnaire investigation was performed over a five year period. A study was performed on 354 patients (161 men and 193 women with mean ages of 66.0 and 70.7 years, respectively) who developed NSAIDs associated upper GI(More)
BACKGROUND/AIMS Our aim was to clarify gastric motility and emptying in LC patients with PHG. METHODOLOGY A total of 30 LC patients (18 with mild gastropathy type, 12 with severe gastropathy type) with a mean age with 65.8 yr were enrolled and 17 healthy participants were recruited as the control group. Electrogastrography was performed to examine gastric(More)
Follicular lymphomas occur rarely in the gastrointestinal tract, representing only 1-3% of all gastrointestinal tract B-cell non-Hodgkin lymphomas. We describe endoscopic analysis of 3 cases of follicular lymphoma in the small intestine using double-balloon endoscopy. Double-balloon endoscopy revealed multiple nodular lesions and elevated white patches,(More)
Muscarinic M3 receptors exist in the gastrointestinal wall in humans and the muscarinic M3 agonist cevimeline hydrochloride (Evoxac) is a candidate therapeutic agent for the treatment of xerostomia in Sjögren's syndrome. However, M3 receptor agonists are not known to show efficacy for diseases associated with abnormal gastrointestinal motility. Herein the(More)
BACKGROUND AND AIM A cut-off value of 2.5 per thousand for the 13C-urea breath test (UBT) is recommended in Japanese persons, based on the result of a multicenter trial in patients prior to treatment for eradication of Helicobacter pylori. The cut-off value of 2.5 per thousand has also been used in the assessment of eradication after treatment. The 6-8-week(More)
In recent years, due to the increasing prevalence of upper gastrointestinal endoscopy, there have been an increasing number of reports on duodenal adenoma and early stage cancer. However, endoscopic techniques for the resection of duodenal adenomas are difficult, due to the anatomical features of the duodenum, and the long distance to the lesion. There have(More)
