Ileus: Difference between revisions

Revision as of 15:09, 5 September 2016

Failure or insufficiency in the peristalsis movement of the gastrointestinal tract which normally moves GI contents from mouth to anus.
Thought to be caused by a disruption in either the neural and/or neuro-hormonal reflexes that normally regulate bowel motility.
Multiple causes possible - likely an inflammatory condition
- Opioid-induced
- Post-operative (irritation +/- opioids)
- Electrolyte imbalance (hypokalemia, hypomagnesemia)
- Colonic pseudo-obstruction (aka Ogilvie's syndrome)
- Gallstone ileus, pancreatitis
Peritonitis (e.g. from infection, malignancy, trauma)
- Burns, acute radiation syndrome
- Spastic ileus (rare: porphyria or lead poisoning)
