pseudo-obstruction

A condition mimicking mechanical bowel obstruction without an anatomical blockage, due to dysmotility.

Full Definition

Pseudo-obstruction, also known as functional intestinal obstruction or Ogilvie syndrome, is a condition characterized by signs and symptoms of bowel obstruction without an identifiable mechanical cause. The condition results from impaired gastrointestinal motility due to dysfunction of the enteric nervous system or smooth muscle. In pediatric patients, pseudo-obstruction can be acute or chronic, and may be associated with conditions such as sepsis, metabolic disorders, medications, or primary motility disorders. Patients present with abdominal distension, vomiting, and inability to pass flatus or stool, similar to mechanical obstruction. Diagnosis requires imaging studies to rule out anatomical obstruction and may include motility studies. Treatment focuses on addressing underlying causes, bowel decompression, and prokinetic agents.

Usage

Usage note: Use hyphenated form 'pseudo-obstruction'; distinguish clearly from mechanical obstruction in documentation.
