How do you differentiate between ileus and obstruction?
Ileus defined as nonmechanical obstruction of bowel usually secondary to inhibition of peristalsis. Small bowel obstruction defined as mechanical obstruction of small bowel due to adhesions, mass, volvulus or other internal or external compression.
What is the difference between pseudo-obstruction and paralytic ileus?
Pseudo-obstruction is clearly limited to the colon alone, whereas ileus involves both the small bowel and colon. The right colon is involved in classic pseudo-obstruction, which typically occurs in elderly bedridden patients with serious extraintestinal illness or in trauma patients.
What are the four hallmark clinical manifestations of a bowel obstruction?
Clinical findings of SBO include crampy abdominal pain, distention, vomiting, and high-pitched or absent bowel sounds.
Is intestinal obstruction the same as paralytic ileus?
Paralytic ileus occurs when the muscle contractions that move food through your intestines are temporarily paralyzed. It’s a functional problem of the muscles and nerves that mimics an intestinal obstruction even when nothing is obstructing them.
How can you distinguish between mechanical and functional obstruction?
There are two types of small bowel obstruction:
- functional — there is no physical blockage, however, the bowels are not moving food through the digestive tract.
- mechanical — there is a blockage preventing the movement of food.
What is the difference between ileus and Ogilvie syndrome?
Ogilvie’s syndrome, also known as ‘paralytic ileus of the colon’, is characterised by pseudo-obstruction of the large intestine in the absence of any mechanical obstructing component; and presents as a massively distended abdomen. If left untreated, it may lead to bowel perforation or ischemia.
What is the difference between Ogilvie’s syndrome and paralytic ileus?
Paralytic ileus may be classified on the basis of the site of hypomotility. Acute colonic pseudoobstruction (Ogilvie syndrome) results from colonic hypomotility and produces a massive but reversible dilation of the colon Summers (1999).
