Intestinal obstruction:
Causes
(Handbook of Diseases)
Adhesions and strangulated hernias usually cause small-bowel obstructions; carcinomas usually cause large-bowel obstructions. A mechanical intestinal obstruction results from a foreign body (fruit pits, gallstones, or worms) or compression of the bowel wall due to stenosis, intussusception, volvulus of the sigmoid or cecum, tumors, or atresia.
A nonmechanical obstruction results from a physiologic disturbance, such as paralytic ileus (see Paralytic ileus), electrolyte imbalance, toxicity (uremia or generalized infection), a neurogenic abnormality (spinal cord lesions), or thrombosis or embolism of mesenteric vessels.
The three forms of intestinal obstruction are:
❑ simple — blockage prevents intestinal contents from passing with no other complications
❑ strangulated — blood supply to part or all of the obstructed section is cut off in addition to blockage of the lumen
❑ close looped — both ends of a bowel section are occluded, isolating it from the rest of the intestine.
In all three forms, the physiologic effects are similar. When intestinal obstruction occurs, fluid, air, and gas collect near the site. Peristalsis increases temporarily as the bowel tries to force its contents through the obstruction, injuring intestinal mucosa and causing distention at and above the site of the obstruction. This distention blocks the flow of venous blood and halts normal absorptive processes. As a result, the bowel begins to secrete water, sodium, and potassium into the fluid pooled in the lumen. This results in distention and enormous amounts of fluid in the gut.
An obstruction in the upper intestine results in metabolic alkalosis from dehydration and loss of gastric hydrochloric acid; a lower obstruction causes slower dehydration and loss of intestinal alkaline fluids, resulting in metabolic acidosis. Ultimately, an intestinal obstruction may lead to ischemia, necrosis, and death.
