Spencer NJ, Hibberd TJ, Travis L, et al. Dyssynergic defecation due to failure of recto-anal coordination frequently affects patients with chronic constipation and overlaps with slow transit constipation. Neurogenesis can occur in the adult due to the presence of enteric neural precursor cells (ENPC); acquired diseases of the enteric nervous system, such as achalasia, may result from a loss of ENPCs like congenital disorders such as Hirschsprung disease (27). Modern IBS diagnostic algorithms follow a clear alley and allow a positive diagnosis of IBS or any other FGID. Home > Medical Interest > Neurogastroenterology & Motility. In Chagas disease, the parasite Trypanosoma cruzi destroys enteric neurons, which leads to achalasia of the lower esophageal sphincter (achalasia cardia).
