Pseudo-obstruction of the colon
The American Journal of Gastroenterology
|May 1, 1976
Summary
Pseudo-obstruction of the colon mimics mechanical blockage without a physical cause, leading to severe bowel dilation. This condition may stem from an imbalance in the autonomic nervous system, specifically sympathetic-parasympathetic neurostimulatory imbalance.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Neurogastroenterology
Background:
- Pseudo-obstruction of the colon presents as a functional disorder mimicking mechanical bowel obstruction.
- It is characterized by progressive proximal colonic dilatation, potentially leading to cecal perforation or necrosis.
Observation:
- Presents eight novel cases of pseudo-obstruction of the colon.
- Analyzes diverse etiologic factors reported in existing literature.
Findings:
- Proposes an anatomicophysiologic mechanism for pseudo-obstruction.
- Hypothesizes that sympathetic-parasympathetic neurostimulatory imbalance underlies the condition.
Implications:
- Highlights the critical need for accurate diagnosis to differentiate from mechanical obstruction.
- Suggests potential therapeutic targets focused on autonomic nervous system regulation.
- Informs clinical management strategies for patients with unexplained colonic distention.
