Pathogenesis & Etiology
Causes of mechanical obstruction= hernias, post-op adhesions, impacted stool, intussusception, tumors, volvulus
Causes of paralytic ileus= post abd surgery (most common), intestinal infections, electrolyte imbalances (hypokalemia), mesenteric ischemia, infections inside abd (appendicitis), use of narcotics
Pathopysiology= Accumulation of GI sections and swallowed air → proximal intestinal dilation → stimulation of cell secretory activity causing more fluid accumulation → increased peristalsis above and below obstruction → frequent loose stools → increased abd distention and intraluminal pressures → compression of mucosal lumphatics → increase of mucosal and capillary bed hydrostatic pressures → third spacing of fluid, electrolytes, and proteins in the intestinal lumen, decreased absorption of fluid and electrolytes into vascular space → fluid loss and dehydration → hypovolemia → shock
