Acute colonic pseudo-obstruction (Ogilvie’s syndrome)

Abstract

Acute colonic pseudo-obstruction is a complication that occurs in hospitalized patients with serious underlying medical or surgical conditions; it is characterized by acute colonic dilatation in the absence of mechanical obstruction. The pathogenesis is incompletely elucidated, but changes in autonomic nervous system function are likely to contribute, as are metabolic and pharmacologic factors. Early diagnosis and appropriate intervention are critical in this disorder, which carries with it considerable morbidity and mortality. Treatment options, consecutively applied, include conservative measures, pharmacologic treatment with neostigmine, and endoscopic decompression. Surgical decompression or resection is necessary in case of refractoriness or perforation, respectively.
