Perioperative Supplementation Enhances Surgical Recovery After Distal Gastrectomy

This study was a pilot study to assess the effect of perioperatively administering oral cystine and theanine in gastric surgery patients and suggested that oral administration of these amino acids may reduce inflammation and promote recovery after gastric surgery. This study postulated that cystine and theanine would reduce excessive inflammation and immune suppression during the perioperative periods of abdominal surgeries, which decreases GSH levels in blood and skeletal muscle. The researchers examined the effects of perioperatively administering cystine and theanine on the postoperative course of gastric cancer patients undergoing distal gastrectomies as a pilot study.
