Which GI function tends to be slower to recover after surgery?

Which GI function tends to be slower to recover after surgery?

• A. Recovery of gastric emptying may be lower than return of small bowel motility
• B. Return of small bowel motility may be slower than gastric emptying
• C. Both recover at the same rate
• D. Pancreatic exocrine function is slower to recover

Answer: (A)

After surgery, the gut typically regains function in a specific sequence, with small bowel motility returning earlier and gastric emptying taking longer to recover. This pattern happens because the stomach’s movement and emptying rely on coordinated vagal signaling and pyloric regulation, both of which are more easily disrupted by surgical stress, inflammation, and opioid-based pain control. The stomach often experiences a more pronounced delay known as a postoperative gastric ileus, resulting in slower emptying until these neurohormonal controls gradually rebalance. In contrast, the small intestine tends to rebound its peristaltic activity sooner as inflammation subsides and the enteric nervous system resumes more effective propulsion. This makes return of small bowel motility faster than the restoration of normal gastric emptying. Pancreatic exocrine function is not typically the limiting factor in early postoperative GI recovery, so it doesn’t generally lag behind gastric emptying in the same way.
