More (Click Discussion Tab)
Colonic Pseudo-obstruction
General Considerations
- Mimics large bowel obstruction without point of obstruction
- Mostly in those over 60, with a slight male predominance
- Apparently due to autonomic nervous system imbalance leading to a dysfunctional distal colon and colonic ileus similar to Hirschsprung’s disease
- The cecum, having the largest resting diameter to start, is the most easily dilated (Laplace law)
- Can lead to ischemic of bowel and perforation
