Factors reducing psychological satisfaction after the Nuss procedure in pediatric patients.

PURPOSE: We examined patient satisfaction with postoperative chest appearance after Nuss procedure and analyzed the factors for postoperative low satisfaction. METHODS: We retrospectively reviewed data of 133 patients who underwent the Nuss procedure from 2000 to 2016. Their medical records, X-rays, and computed tomography scans were evaluated. Haller index and concave rate were used as objective indices of the deformity. The questionnaires were used to evaluate satisfaction with the chest appearance by a linear scale including five markers (1: dissatisfaction, 5: satisfaction). The patients were divided into two groups: the low satisfaction (score = 1, 2) and the high satisfaction (score = 3-5). RESULTS: The median age during the Nuss procedure was 7.6 (interquartile range, 5.8-12.8) years. Out of 133, 65 patients replied, and the mean postoperative satisfaction score was 3.8 ± 0.2. Out of the 65 respondents, 16 patients (24.6%) were classified as low satisfaction group. Haller index and concave rate were significantly higher and the previous instances of chest operation history were more frequent in the low satisfaction group than in the high satisfaction group, although there was no significant intergroup difference in terms of the postoperative concave rate. CONCLUSIONS: Severe deformity and previous chest operation history were considered to be factors for low satisfaction.
