A slowing of gastrointestinal motility that is not associated with mechanical obstruction.
Most commonly presents following surgery and usually lasts 2 to 4 days.
Prolonged postoperative ileus contributes significantly to longer hospitalisation and increased healthcare costs.
Treatment includes bowel rest, supportive care, and treatment of any underlying exacerbating factors.
Prevention requires a multi-modal approach, including the substitution of postoperative opioid analgesia with non-steroidal anti-inflammatory drugs and thoracic epidural analgesia, early enteral feeding, early ambulation, and the use of laparoscopy rather than laparotomy whenever possible.
Ileus is a slowing of gastrointestinal (GI) motility accompanied by distention, in the absence of a mechanical intestinal obstruction. It is a diagnosis of exclusion after bowel obstruction has been ruled out. It usually occurs in response to physiological stress, including surgery, sepsis, metabolic derangements, and Gl diseases.
