Constipation: a common problem in patients with neurological abnormalities.
Constipation is a frequent complaint among patients with different neurological diseases. This review provides a brief account of the numerous conditions affecting the central, peripheral and intrinsic (enteric) nervous systems in which constipation can be the only clinical manifestation or a component of a complex syndrome. Recent neuropathophysiological acquisitions show that any structural or functional impairment of the intrinsic innervation of the gut, including both developmental (i.e., Hirschsprung's disease and intestinal neuronal dysplasia) and acquired (i.e., either degenerative or inflammatory neuropathies) disorders, can be associated with constipation. Constipation may also arise from derangements of the peripheral nervous system, including diabetes and primary chronic autonomic failure (pandysautonomias). Finally, in the central nervous system, a wide array of disorders (post-traumatic, degenerative, ischaemic or neoplastic) are recognized to determine bowel dysfunction, ultimately leading to constipation. Further understanding of the fine pathophysiological mechanisms through which the intrinsic and extrinsic nerve supplies to the digestive system are involved in idiopathic constipation or in diseases generating this symptom will hopefully lead to a better treatment of this frequent pathological condition.

Clinical use of manometry for the diagnosis of intestinal motor abnormalities.
Digestive symptoms suggestive of intestinal motor disorders, such as abdominal pain and distension, fullness, vomiting, constipation and diarrhoea, are very common and non-specific, and may be clinical manifestations of both organic and functional diseases. Both radiology and endoscopy are important in the diagnosis of structural gastrointestinal lesions that can affect motility and offer indirect signs of impaired gastrointestinal functions, but the diagnosis of gut motility disorders currently relies on the manometric assessment of contractile activities. Small bowel manometry helps to identify normal motility features and consequently to identify abnormal motor patterns. Small bowel manometry can help to differentiate mechanical obstruction from pseudo-obstruction and neurogenic from myogenic motor disorders. Manometry is an invasive technique which is not well accepted by patients and requires specific skills from investigators. Also, manometric assessment is limited to referral centres with a specific interest in the field of digestive functions, in general, and motility, in particular. Only patients who remain undiagnosed after extensive traditional work-up and fail repeated courses with medical therapy should be referred for the manometric test. Understanding the underlying pathophysiologic mechanisms of abnormal motility and developing new therapies are the goals of the current research in this fascinating field of medicine.
