[2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]

The length of the small intestine can vary greatly, from as short as 2.75 m (9.0 ft) to as long as 10.49 m (34.4 ft). [6] On average it is about 6.1 m (20 ft). [ 1 ] Due to this variation it is recommended that following surgery the amount of bowel remaining be specified rather than the amount removed.
A bowel obstruction is generally a mechanical obstruction of the gastrointestinal tract and can occur anywhere from the Ligament of Treitz to the anus. When the obstruction affects only the small intestine, it is generally referred to as a small bowel obstruction to distinguish it from a colonic obstruction, which may or may not affect the ...

The small bowel feces sign results from stagnation of enteric contents within dilated segments of the small intestine. [1] When intestinal motility is impaired due to obstruction, progressive dehydration of luminal contents occurs, leading to the formation of solid particulate matter that mimics feces. [3]
