Questionnaire-Based Survey on Epidemiology of Functional Gastrointestinal Disorders and Current Status of Gastrointestinal Motility Testing in Asian Countries.

Background/aims: Functional gastrointestinal disorders (FGIDs) are diagnosed and classified using the latest Rome IV criteria, released in 2016. Epidemiology of FGID diagnosed by the Rome IV criteria and current clinical application of gastrointestinal motility testing in Asian countries are not well known. The aims of this survey are to elucidate the present situation of epidemiology and diagnostic tests of FGID in clinical practice in some East and Southeast Asian countries.

Management of Gastroesophageal Reflux Disease in Asian Countries: Results of a Questionnaire Survey.

Introduction: The Asia-Pacific consensus on the management of gastroesophageal reflux disease (GERD) and the GERD treatment guidelines of 2015 drawn up by the Japanese Society of Gastroenterology were proposed, and GERD management in Asian regions was assumed to be performed based on these consensuses. In this environment, the current status of GERD management in clinical practice among Asian regions is less well-known.

Objective: This questionnaire-based consensus survey was performed to clarify the current status of management of GERD in clinical practice in Asian regions.

Questionnaire-Based Survey on Management of Ulcerative Colitis-Associated Cancer in East Asian Countries.

Emerging Targets to Relieve Fat Stress-Induced Liver Diseases: UDCA, Tocotrienol, ω-3 PUFAs, and IgY Targeted NPC1L1 Cholesterol Transporter.

Fat stress-induced liver disease is a hepatic manifestation of metabolic syndrome initiated by excess fat accumulation and encompasses a wide spectrum of diseases from non-alcoholic fatty liver disease to nonalcoholic steatohepatitis, a precursor lesion progressing to more aggressive liver cirrhosis and hepatocellular carcinoma. Although the incidence of these fat stress-induced liver diseases is rapidly increasing worldwide in parallel with the growing epidemics of obesity and metabolic diseases, its exact pathogenesis is not well defined. Although obesity, sedentary life-style, altered dietary pattern, insulin resistance, altered intestinal barrier function, inflammatory cytokines, and oxidative stress have been acknowledged as contributing factors because of the indefinite pathogenesis of metabolic diseases, the only reliable treatment is lifestyle intervention composed of restrictive diet and exercise.

Survey of clinical practice for irritable bowel syndrome in East asian countries.

Aim: Sociocultural factors are important because their different effects on the features of irritable bowel syndrome (IBS) between countries will provide clues towards solving this problem. The aims of this study were to depict the clinical realities of IBS in East Asian countries and test the hypothesis that the diagnosis and treatment of IBS differ between countries.

Subjects And Methods: Study participants were 251 physicians involved in the clinical practice of IBS at major institutions in Japan, South Korea, China, the Philippines, Indonesia and Singapore.

The Korean perspective of Helicobacter pylori infection: lessons from the Japanese government's policy to prevent gastric cancer.

The guideline of the Korean College of Helicobacter and Upper Gastrointestinal Research group for Helicobacter pylori infection was first produced in 1998, when definite indication for H. pylori eradication is early gastric cancer in addition to the previous indications of peptic ulcer (PUD) including scar lesion and marginal zone B cell lymphoma (MALT type). Though treatment is recommended for the relatives of a patient with gastric cancer, unexplained iron deficiency anemia, and chronic idiopathic thrombocytopenic purpura, a consensus treatment guideline is the treatment of PUD, MALToma, and gastric cancer in Korea.

A questionnaire-based survey on the diagnosis and management of inflammatory bowel disease in East Asian countries in 2012.

Background And Aim: The prevalence and incidence of inflammatory bowel disease (IBD) are lower in East Asia than in Western countries; however, marked increases have recently been reported. The clinical diagnosis and medical management of IBD in East Asia differ from those in Western countries. A questionnaire-based survey was performed to gather physicians' current opinions on IBD in different East Asian countries.
