Which of the following make mechanical obstruction of the intestinal lumen of the small or large bowel an acute emergency?
Julli [10]

Distention from accumulating gas and fluid impede venous return, leading to bowel wall ischemia.

<u>Explanation:</u>

When the bowel lumen is obstructed, the gases and fuids starts accumulating as a repose to the obstruction. The accumulated fluid and gases results in the swelling or enlargement. This will result in the production of electrolytes and water inside the mumen that is in obstruction. The wall of the bowle will also enlarge and becomes swollen.

As more and more fluid and gas gets accumulated in the bowel, the bowel wall will be enlarged and as there is an increase in the pressure due to this accumulation, the fluid starts to leak from the wall. This will enter peritoneum and necrosis. This will result in an acute emergency when it becomes serious.
