Organization of Neurogastroenterology and Motility units with a multidisciplinary, patient-centered perspective.

Neurogastroenterology and Motility is a Gastroenterology subspecialty dealing with the management of gastrointestinal (GI) motor diseases and disorders of gut-brain interaction (DGBI). Both types of conditions may impair the nutritional status of patients - In the case of motility disorders, because deficient gastrointestinal motility may impair appropriate food digestion and absorption; in DGBI because development of gastrointestinal symptoms may impair appropriate patient nutrition. In both cases, different studies have shown that patients start restrictive diets on their own, without supervision of a dietician, which leads to nutritional deficits in many cases. Likewise, psychological factors like stressful situations or anxiety may trigger gastrointestinal symptoms in these patients, mainly in those with DGBI. Recent studies comparing a patient-centered approach that includes medical treatment, dietary modifications, and behavioural interventions with gastroenterologist-only standard care have shown a greater proportion of improved symptoms, psychological status, and quality of life, as well as reduced costs in patients allocated to the multidisciplinary treatment arm. In conclusion, there is growing evidence in favour of dietary and behavioural interventions by specialized professionals, coupled with appropriate medical evaluation and treatment by a gastroenterologist. Hence the importance of developing reference units in which comprehensive, individualized management may be offered. Multidisciplinary models improve clinical outcomes and patient satisfaction, which should result in a reduction of direct and indirect costs.  .
