Paediatric constipation for adult surgeons − article 2: new microscopic abnormalities and therapies

Chronic constipation is a common condition in both adults and children. Children with chronic constipation frequently have symptoms that continue into adulthood. In the second part of the review we describe advances in the identification of abnormalities in the control of motility. The role of neurotransmitters in both paediatric and adult constipation is examined and the radical rethink of colonic dysmotility caused by the re-emergence of interstitial cells of Cajal is discussed. The recognition of chronic constipation as an heterogenous condition has led to the introduction of new therapies. Antegrade washouts through appendix stomas and an exciting new treatment with electrical interferential therapy may, in the future, result in a less invasive approach to the management of chronic constipation. An improved understanding of the assessment and management of chronic constipation in childhood is also likely to reduce the frequency and morbidity of chronic constipation in adults.
