In our study, we found 61 patients: 20 (32.8%) positive patients before surgery, 10 of whom were depressed, 7 of whom were depressed and anxious, and 3 of whom were anxious. After surgery, there were 29 (47.5%) positive patients, 15 of whom were depressed, 12 of whom were depressed and anxious, and 2 of whom were anxious.
