Pseudo-Obstruction and Other Primary Motility Disorders - Pediatric
Presented by Nikhil Thapar, MRCP, FRCPCH, FRACP, PhD

Presentation Overview
Primary gastrointestinal motility disorders are a heterogeneous group of disorders that affect the neuromuscular (nerve and muscle) components of the gastrointestinal tract and limit its ability to push contents along the length of its lumen. These disorders include esophageal achalasia, gastroparesis, intestinal pseudo-obstruction, Hirschsprung disease and slow transit constipation. Recent year have seen attempts to standardise the diagnosis and management of such disorders. Overall, their diagnosis needs to be timely, accurate and definitive, which requires expertise of the conditions and criteria for their diagnosis as well as access to appropriate investigative tools (e.g. motility testing, tissue assessment). Management is largely supportive and often best served in specialist centres with an expert multidisciplinary team. The mainstay for therapy includes the provision of essential nutrition, reducing symptoms and disease progression, limiting complications and ultimately improving outcomes and quality of life. For most conditions this currently involves surgery. The future holds potential for a better understanding of these conditions as well as improved diagnostics and more effective innovative therapies.
