After how many days can a patient develop a prolonged postoperative ileus?

1. 2 days

2. 4 days

3. More than 4 days

4. 6 days

The correct answer is: More than 4 days

A prolonged postoperative ileus is typically defined as one that persists beyond a certain timeframe following surgery. Generally, it is expected that the intestines will start to regain function within the first few days post-surgery. However, when the recovery of bowel function is delayed and does not occur within 4 days, it is considered prolonged. In surgical settings, it is common to observe a return of bowel motility within 24 to 72 hours postoperatively. If the condition continues for more than 4 days, the patient may be experiencing a prolonged postoperative ileus, which can be caused by various factors such as the type of surgery, presence of narcotics, electrolyte imbalances, or underlying health conditions. In clinical practice, recognizing that a postoperative ileus lasting more than 4 days may require further medical evaluation and management is crucial. This includes identifying potential causes and implementing strategies to promote bowel function.
