Current Status Diseases of the Colon & Rectum


Purpose: Postoperatively, some patients experience a prolonged inhibition of coordinated bowel activity, which causes accumulation of secretions and gas, resulting in nausea, vomiting, abdominal distension, and pain. This prolonged inhibition can take days or weeks to resolve and often is referred to as postoperative paralytic ileus lasting more than three days after surgery. This article reviews the etiology, pathophysiology, and treatment options of post-operative ileus. Methods: The relevant literature from 1965 to 2003 was identified and reviewed using MEDLINE database of the U.S. Medical Library of Medicine. Both retrospective and prospective studies were included in this review. Results: The pathophysiology of postoperative ileus is multifactorial. The duration of postoperative ileus correlates with the degree of surgical trauma and is most extensive after colonic surgery. However, postoperative ileus can develop after all types of surgery including extra-peritoneal surgery. A variety of treatment options have been used to decrease the duration of postoperative ileus. However, it is difficult to compare these studies because of small sample sizes and differences in operations performed, anesthesia protocols provided both intraoperatively and post-operatively, patient comorbidities, and in the measured end points, such as the time to the presence of bowel sounds, flatus, or bowel movements, tolerance of solid food, or discharge from the hospital. However, despite these drawbacks, some conclusions can be made. Conclusions: Paralytic postoperative ileus continues to be a significant problem after abdominal and other types of surgery. The etiology is multifactorial and is best treated with a combination of different approaches. Currently, the important factors that could effect the duration and recovery from postoperative ileus include limitation of narcotic use by substituting alternative medications such as nonsteroidals and placing a thoracic epidural with local anesthetic when possible. The selective use of nasogastric decompression and correction of electrolyte imbalances also are important factors to consider.
