BACKGROUND Indomethacin enhances small intestinal epithelial cell apoptosis, which may account for mucosal ulceration. However, the involvement of autophagy in indomethacin-induced enterocyte damage is unreported. METHODS Using light microscopy and electron microscopy techniques, Western blot analysis, and pharmacological inhibition of autophagy, we(More)
BACKGROUND The incidence and severity of gastroesophageal reflux disease (GERD) in Japan tends to increase in elderly women. Rikkunshito (RKT), a traditional Japanese medicine, acts as a prokinetic agent and improves gastric emptying and gastric accommodation. Our previous prospective randomized placebo-controlled study showed that RKT combined with a(More)
BACKGROUND Endoscopic submucosal dissection (ESD) has been developed for early gastric cancer (EGC). Helicobacter pylori eradication therapy has been reported to have a preventive effect against metachronous recurrence of EGC after ESD. However, the efficacy and safety of eradication therapy on ESD-induced ulcer healing are not clear. In a randomized(More)
BACKGROUND There is a lack of consensus regarding the risk of postoperative hemorrhage in patients on antithrombotic therapy who undergo endoscopic submucosal dissection (ESD).We examined postoperative bleeding rates and risk factors for postoperative hemorrhage from post-ESD gastric ulcers in patients on antithrombotic therapy. METHODS The subjects of(More)
Endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD) is not normally indicated for an obstructed right intrahepatic bile duct (IHBD). The technical feasibility and clinical efficacy of a novel technique of EUS-BD for right IHBD obstruction were evaluated. A total of 11 patients underwent drainage using either a left or a right biliary access route.(More)
BACKGROUND AND AIM Endoscopic submucosal dissection (ESD) is reported to be a safe and reliable procedure for the elderly, but these reports could have already had a bias at the time ESD was performed. However, the reports have not clearly stated the criteria of indications. In the present study, we retrospectively elucidated the usefulness and problems of(More)
BACKGROUND Low-dose aspirin (LDA) frequently causes small bowel injury. While some drugs have been reported to be effective in treating LDA-induced small intestinal damage, most studies did not exclude patients with mild damage thought to be clinically insignificant. AIM We conducted a multicenter, randomized, double-blind, placebo-controlled trial to(More)
AIM To assess adalimumab's efficacy with concomitant azathioprine (AZA) for induction and maintenance of clinical remission in Japanese Crohn's disease (CD) patients. METHODS This retrospective, observational, single-center study enrolled 28 consecutive CD patients treated with adalimumab (ADA). Mean age and mean disease duration were 38.1 ± 11.8 years(More)
The gut incretin glucagon-like peptide-1 (GLP-1) and the intestinotropic hormone GLP-2 are released from enteroendocrine L cells in response to ingested nutrients. Treatment with an exogenous GLP-2 analogue increases intestinal villous mass and prevents intestinal injury. Since GLP-2 is rapidly degraded by dipeptidyl peptidase 4 (DPP4), DPP4 inhibition may(More)
