BACKGROUND AND STUDY AIMS Each year at our institution we have been performing over 100 endoscopic mucosal resections (EMRs) for gastric tumor. However, there are some tumor locations where it is difficult to carry out this procedure, such as the lesser curvature or posterior wall of the gastric body, the cardia, and the lesser curvature of the antrum. To(More)
Background: In tumor cells, the enzyme orotate phosphoribosyl transferase (OPRT) contributes to 5-fluorouracil (5-FU) phosphorylation and another enzyme, dihydropyrimidine dehydrogenase (DPD), is associated with 5-FU catabolic action. We measured OPRT and DPD activities and, to determine whether their levels might serve as indicators of 5-FU sensitivity,(More)
The efficacy of prophylactic hemostasis with endoclips after polypectomy is still controversial. The purpose of this study is to evaluate the efficacy of prophylactic hemostasis for postpolypectomy mucosal defects using endoclips under infrared imaging. Patients with colon polyps who were endoscopically treated at Jikei University Aoto Hospital were(More)
BACKGROUND Foveolar gastric metaplasia of the duodenum is a frequent but not as yet considered correlate of endoscopically detected duodenal polyps. The majority of foveolar gastric metaplasias associated with polyps presented a typical benign endoscopic appearance and they were diagnosed by biopsy. Here we report a case of a surgical-resected foveolar(More)
Experimental studies have shown ligation results in replacement of submucosal structures, including varices, with scar tissue resulting in eradication of varices. Elastic band ligation is equal in efficacy to sclerotherapy for control of active bleeding from esophageal varices. Ligation appears superior to sclerotherapy for long-term prevention of recurrent(More)
At our institute, we have tried to increase the patient's quality of life (QOL) by endoscopic stenting for upper intestinal stenosis due to malignant tumor, which could not be treated by surgery or chemotherapy. We report the endoscopic stenting and home therapy for those patients. The subjects were 44: (esophageal stenosis: 13 cases, biliary stenosis: 31(More)
Five patients with distant metastasis from colorectal cancer who had good nutrition were treated with continuous intravenous administration of 5-FU infusion (400-450 mg/body/day) by infusor. The other five patients with advanced stomach cancer who could not have so good nutrition were receiving home parental nutrition (HPN, 1,200 kcal/day) and continuous or(More)
