Can surgery for stomach or esophageal cancer cloud the mind?

This study follows 130 adults undergoing surgery for stomach or esophageal cancer to see how often they experience postoperative delirium—a state of confusion and disorientation after anesthesia. Researchers will also check whether depression, frailty, poor nutrition, or muscle loss before surgery make delirium more likely. Participants who experience delirium may be invited to share their experience in an interview, helping doctors understand and potentially prevent this complication.
