BACKGROUND AND PURPOSE: 5-HT4 receptor agonists have been shown to be effective to treat various gastrointestinal tract disorders. However, a lack of selectivity against off-targets has been a limiting factor. EXPERIMENTAL APPROACH: The binding affinity and selectivity of YH12852 for human 5-HT4(a) receptor in CHO-K1 cells were evaluated using radioligand binding assays, and agonistic activity was assessed using a beta-lactamase reporter system. Contractile activity and propulsive motility were measured in isolated guinea pig distal colon...

Morbid obesity is a lifelong disease, and all patients require complementary follow-up including nutritional surveillance by a multidisciplinary team after bariatric procedures. Pancreatic exocrine insufficiency (PEI) refers to an insufficient secretion of pancreatic enzymes and/or sodium bicarbonate. PEI is a known multifactorial complication after upper gastrointestinal surgery, and might constitute an important clinical problem due to the large number of bariatric surgical procedures in the world. Symptoms of PEI often overlap with sequelae of gastric bypass, making the diagnosis difficult...

Background: In Japan, there has been a lot of reports showing an association between facial flushing after light alcohol consumption and heterozygosity for inactive aldehyde dehydrogenase-2 (ALDH2). Persons with inactive ALDH2 may have a higher risk of alcohol-related oral, pharyngeal and esophageal cancers, compared with those with wild-type ALDH2. The purpose of this study was to examine whether flushers with oral or pharyngeal squamous cell carcinoma have an increased risk of synchronous or metachronous cancer of the upper gastrointestinal (UGI) tract...

BACKGROUND: Laparoscopic wedge resection (LWR) is used to treat gastric submucosal tumors (SMTs). However, LWR can injure the cardia if tumors are near the esophagogastric junction (EGJ), resulting in gastric stenosis. This study's purpose was to summarize our experience with endoscope-assisted LWR for gastric SMTs within 3 cm of the EGJ and to verify the procedure's feasibility and safety. METHODS: Data from 91 consecutive patients with gastric SMTs within 3 cm of the EGJ who underwent endoscope-assisted LWR at our hospital from 2007 to 2017 were obtained from a prospectively maintained database...

Chlamydia has been detected in the gastrointestinal tracts of humans and animals. We now report that gastrointestinal Chlamydia muridarum is able to induce robust transmucosal protection in mice. C. muridarum colonization in the gastrointestinal tract correlated with both a shortened course of C. muridarum genital infection and stronger protection against subsequent genital tract challenge infection. Mice pre-inoculated intragastrically with C. muridarum became highly resistant to subsequent C. muridarum infection in the genital tract, resulting in prevention of pathology in the upper genital tract...

BACKGROUND & AIMS: Esophageal atresia is rare, but improved surgical and intensive care techniques have increased rates of survival in children, so there are now many adults with this disorder. Many patients with esophageal atresia develop gastroesophageal reflux (GER), raising concerns about increased risk of Barrett's esophagus (BE; prevalence of 1.3%-1.6% in general population) and esophageal carcinoma. We assessed the prevalence of BE and esophageal carcinoma in this population. METHODS: We performed a prospective study of 289 patients with esophageal atresia at the Department of Gastroenterology and Hepatology at Erasmus MC University Medical Center in The Netherlands, from May 2012 through March 2017...

BACKGROUNDS/AIMS: Nonalcoholic fatty liver disease (NAFLD), a hepatic manifestation of the metabolic syndrome, is associated with gastroesophageal reflux disease in cross-sectional studies, but a prospective association has not been evaluated. The current study aimed to determine whether NAFLD increases the risk of incident reflux esophagitis in a large cohort study. METHODS: We conducted a cohort study of 34,063 men and women without reflux esophagitis or other upper gastrointestinal disease at baseline who underwent health check-up examinations between January 2003 and December 2013...

Objective: The percentage of patients with nonsteroidal anti-inflammatory drugs (NSAIDs) and low-dose aspirin- (LDA-) induced ulcers who complain of gastrointestinal symptoms has generally been considered to be low. The aim of this study was to examine and compare the symptoms and quality of life (QOL) at peptic ulcer onset. Methods: This study involved 200 patients who were confirmed by endoscopy to be in the acute stage of gastroduodenal ulcer (A1-H1). Patients completed a self-administered questionnaire (Global Overall Symptom score and SF-8) at ulcer onset, and data were compared between NSAIDs/LDA ulcers and non-NSAIDs/LDA ulcers...

About 10% of oesophagogastroduodenoscopies (OGDs) and colonoscopies are done for investigation of iron deficiency anemia (IDA) . Much of the existing guidance on investigation of IDA predates CRC screening, which has driven significant improvements in colonoscopy quality and completion rates, as well as a reduction in Helicobacter pylori prevalence and increase in PPI usage, and therefore probably needs re-consideration. New investigations, e.g. CT colonography, enteroscopy and capsule endoscopy have also been introduced...

Introduction: The growing incidence of gastrointestinal diseases forces to improve both imaging techniques and the identification of the population with a greater risk of a disease. Identification of lesions located inside the wall of intestinal tract or in close proximity often was not possible using endoscopy or computed tomography. Aim: The study was a retrospective evaluation of the occurrence of submucosal lesions (SML) and thickened wall (TW) of the upper gastrointestinal tract (UGIT) depending on age and sex...
