Neurogastroenterology: The Cinderella among the ecological niches of gastroenterology?

Abstract

Neurogastroenterology (NGE) refers to a specific sub-specialty of gastroenterology that investigates the pathophysiology, diagnostics and therapeutic approaches to the "disorders of gut-brain interaction" (DGBIs), frequently encountered in clinical practice and often associated with poor quality of life and high healthcare costs. Two recent national surveys, focused on common DGBIs, highlighted two main issues. Despite the high incidence of DGBIs there is a lack of awareness and appropriate training to effectively treat these conditions and a lack of specific referral centers in each region. Indeed, specific training and a multidisciplinary approach are required to properly manage these patients, but these are not always available. As a result, NGE lacks attractiveness for many young gastroenterologists. We believe that NGE has great potential to emerge among the various sub-branches of gastroenterology. However, its growth is limited by lack of specific training, knowledge, accessibility, diagnostic capabilities, multidisciplinary integration, and financial investments in research. To bridge this gap, it would be helpful to overcome these limits through an increase in specific training concerning DGBIs among students, residents, physicians and general practitioners. This, coupled with improved access to advanced diagnostic tests, innovative therapies, and a better multidisciplinary approach, could help expand the knowledge in this still niche area and achieve better treatment outcomes for patients.
