Postoperatively, a patient develops a paralytic ileus. What is the most likely cause?

• A. She did not ambulate soon enough after surgery.
• B. She should have eaten a full diet after surgery to stimulate peristalsis.
• C. She is experiencing the effects of the anaesthetic and the manipulation of the bowel.
• D. She did not receive a rectal suppository to stimulate peristalsis on the first day after surgery.

Answer: (C)

Paralytic ileus after surgery happens when the gut’s movement slows or stops for a time because the bowel has been affected by the operation and anesthesia. The most likely trigger is the temporary suppression of intestinal motility from the combination of anesthetic agents and the physical manipulation of the bowel during the procedure. This disrupts the neural signals and smooth muscle contractions that normally propel contents through the intestines, so peristalsis doesn’t resume promptly. Ambulating early after surgery can help reduce ileus by stimulating circulation and gut activity, but it isn’t the primary cause. Eating a full diet right away isn’t the cause either and rectal suppositories aren’t the standard reason for a postoperative ileus. Understanding this helps guide expectant management: monitor for return of bowel sounds and passage of gas or stool, keep the patient comfortable and hemodynamically stable, and use pain relief strategies that minimize opioid-related slowing of gut motility.
