Classification

There is no specific system for classification of postoperative ileus. However, based on etiology, postoperative ileus may be classified into drug induced ileus, metabolic & electrolyte abnormalities ileus and systemic disorder induced ileus.

• Postoperative Ileus

It is a temporary paralysis of a portion of the intestines typically after an abdominal surgery. Since the intestinal content of this portion is unable to move forward, food or drink should be avoided until peristaltic sound is heard from auscultation of the area where this portion lies.

• Acute colonic pseudoobstruction (Ogilvie's syndrome)

Postopertive ileus

Drug induced

Metabolic & electrolyte abnormalities

Systemic disorders

•Opiates •Anticholinergics •Autonomic blockers •Psychotropic drugs •General anesthesia

•Hypokalemia •Hyponatremia •Hypomagnesemia •Hypophosphatemia

•Diabetes •Hypoparathyroidism •Renal failure •Sepsis •Pneumonia
