Advances in Motility & in Neurogastroenterology: AIMING for the Future - Single Topic Symposium

Chair: Anil Darbari MD, MBA 

Associate Professor of Pediatrics
George Washington University School of Medical Health Sciences
Director, Comprehensive GI Motility Center
Children's National Medical Center


This single topic symposium aims to bring together world’s leading clinicians and scientists in a didactic exchange on the state of the art in pathophysiology, diagnosis and management of pediatric gastrointestinal motility related sensory conditions, and to build a foundation for advancing new scientific and therapeutic strategies. The symposium will emphasize and promote the participation of young investigators, including trainees and junior faculty.
We aim to provide a foundation for future research and to inspire young investigators to study and practice pediatric neurogastroenterology and gastrointestinal motility.

The symposium will provide cutting edge presentations from adult and pediatric practitioners and is organized into modules that define the state of the art in the diagnosis and management of functional disorders of the gastrointestinal tract, frame key questions, define the underlying pathophysiology, and highlight novel therapies on the horizon.

Participants will also have hands-on demonstrations of the most up-to-date equipment and can contribute to discussions about neuromodulatory therapies in smaller groups. This symposium will provide the participants with an in-depth understanding of the current field of pediatric neurogastroenterology and motility, highlighting how the field is advancing, AIMING for the future.
