[Acute colonic pseudo-obstruction].

Abstract

Colonic Pseudo-obstruction is a poorly understood syndrome. It was first described by Ogilvie in 1948 and is characterized by signs of large bowel obstruction with a non-mechanical etiology. The suggested cause of this pathophysiology is an imbalance in the autonomic nerve supply to the colon. The syndrome affects mainly old, bedridden patients, usually hospitalised for non-colonic causes. The actual incidence of this syndrome is unknown, mainly due to the fact that spontaneous recovery may occur. When massive abdominal distention is apparent, diagnosis and treatment are usually problematic and other causes of obstruction must be ruled out. It is usually managed by water soluble contrast administered orally or rectally, or by colonic decompression. In extreme cases surgical treatment is required with significant morbidity and mortality. Pharmacologic management with parasympathomimetic drugs has been suggested recently. We describe the successful treatment of a patient with neostigmine and review the current literature.
