Can structured rehabilitation before surgery reduce pneumonia risk for esophageal cancer patients?
Pneumonia is a common and serious complication after esophagectomy (surgery to remove part of the esophagus). Structured rehabilitation before surgery, often called prehabilitation, aims to prepare the body for the stress of surgery. Research suggests that comprehensive programs combining exercise, nutrition, and education can lower the chance of developing pneumonia after the operation.
What the research says
A 2025 systematic review found that structured perioperative rehabilitation, which includes care before and after surgery, reduces the risk of postoperative pneumonia in esophageal cancer patients 6. The review emphasized that programs with at least two core components—such as exercise plus nutrition or education—were more effective than single-component interventions 6. However, the review noted high variability among studies, meaning the exact best program is not yet clear 6.
Another study on perioperative swallowing rehabilitation (exercises to improve swallowing) after radical esophagectomy showed that while swallowing function improved, it did not significantly reduce the rate of aspiration pneumonia 9. This suggests that pneumonia prevention may require broader rehabilitation beyond just swallowing exercises.
Additionally, a randomized trial found that adding a pyloroplasty (a surgical procedure on the stomach) during minimally invasive esophagectomy reduced the combined risk of pneumonia or anastomotic leak compared to no pyloroplasty 8. While not a rehabilitation technique, this highlights that multiple strategies can help lower pneumonia risk.
Overall, the evidence supports that structured rehabilitation before surgery—especially multimodal programs—can reduce pneumonia risk, but more research is needed to define the optimal approach 6.
What to ask your doctor
- What types of preoperative rehabilitation programs are available at this hospital?
- Does the program include multiple components like exercise, nutrition counseling, and education?
- How long before surgery should I start rehabilitation to get the most benefit?
- Are there any risks or side effects of participating in a prehabilitation program?
- Can you refer me to a specialist who can design a personalized rehabilitation plan?
