Adynamic Ileus Definition, Symptoms, Causes, Treatment

Adynamic ileus is a disease in which peristaltic movement of small intestine and large intestine cease or stop. As the name "ileus" indicates the part of small intestine i.e. ileum. It occurs due to failure of nerve stimulation of small intestine. In Adynamic ileus bowel movement stops and food do not passes on to colon or rectum. It is described as paralysis of motion of small intestine. Usually adynamic ileus is asymptomatic and does not show symptoms. But if it show symptoms then its symptoms resemble with the symptoms of mechanical bowel obstruction. Common symptoms involve abdominal pain, cramps, gas distension and vomiting. Constipation is the most common and visible symptom of adynamic ileus.

Adynamic ileus can occur as a result of metabolic disorder, secondary to drugs, abdominal surgery, abdominal trauma, head injury and sepsis. Imaging of adynamic ileus shows gaseous distension of small and large intestine. If adynamic ileus is localized, then imaging shows sentinel loop. Adynamic ileus is sometimes associated with colicky pains of gall bladder or kidney stones. Treatment involve intubation of intestine via long balloon tipped tube. Because of deficiency of body fluids, fluid supplements are provided to patient in the form of Intravenous fluid administration.
