Perspectives on paralytic ileus.

Paralytic ileus is the condition where the motor activity of the bowel is impaired, usually not associated with a mechanical cause. Although the condition may be self-limiting, it is serious and if prolonged and untreated will result in death in much the same way as in acute mechanical obstruction. Management of paralytic ileus depends on the knowledge of the most likely cause and the perceived chance of resolution without operation. Postoperative ileus is the single largest factor influencing length of hospital stay after bowel resection, and has great implications for patients and resource utilization. Early diagnosis and correct management is essential in reducing complications. This article briefly outlined the plausible pathophysiological mechanisms and clinical implications of paralytic ileus.
