[Perioperative nutritional support with immune-enhancing diet for surgical closure of open thoracic window].

Immunonutrition, which is a therapeutic approach to modulate acute surgical or medical conditions, has been proven to decrease surgical site complications in patients undergoing major elective surgery for upper gastrointestinal and esophageal malignancy. For immunonutrition to be carried out effectively, specific nutrients called pharmaconutrients are quite important. In our case, to enhance the perioperative nutritional status of the patient, special formulas supplemented with specific pharmaconutrients, which are arginine and omega-3 fatty acids, were orally administered. The open thoracic window for chronic empyema caused by postoperative bronchopleural fistula was successfully closed. Perioperative immunonutrition is likely to have beneficial effect in decreasing postoperative infectious complications in high-risk malnourished thoracic surgical patients.
