Peripheral parenteral nutrition improves short-term nutritional status and inflammatory reaction after colorectal resection surgery: A randomized clinical trial

This study investigates whether early postoperative peripheral parenteral nutrition (PPN) can improve short-term nutritional status and reduce inflammatory responses in patients undergoing colorectal resection surgery compared to conventional saline treatment. The findings indicate that PPN is safe and associated with a lower inflammatory response and better nitrogen balance, suggesting its potential as a beneficial nutritional strategy in postoperative care.
