Surgical design and novel modified Nuss procedure for pectus excavatum / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To explore the surgical design and efficacy of novel modified Nuss procedure for pectus excavatum (PE). Methods    We retrospectively analyzed the clinical data of 903 patients with PE who were treated by the new kind of steel bar and the novel modified Nuss procedure. There were 716 males and 187 females at mean age of 2-45 (12.1±6.8) years. Preoperative chest CT scans Haller index (HI) was 3.1-15.2 (4.6±1.3), with 38 patients of mild PE (HI<3.2), 302 patients of moderate PE (HI 3.2-3.5), 521 patients of severe PE (HI 3.6-6.0), and 42 patients of extremely severe PE (HI>6.0). The operative time, operative blood loss, hospital stay time as well as postoperative complications were reviewed and analyzed. Results    All of the 903 patients successfully completed the surgery. The mean operative time was 20-45 (25.2±2.6) min for primary PE and that for special type of PE (including recurring PE, PE patients after heart disease operation and those corrected by 2 bars) was 48-150 (63.5±28.1) min. Blood loss was less than 10 mL for primary PE and 15-50 (23.5±5.5) mL for special type of PE. Postoperative hospital stay was 3-15 (4.5±1.6) d. A total of 845 patients (93.6%) required 1 steel bar insertion, 58 patients (6.4%) required 2 steel bars. Postoperative evaluation of the surgery outcomes revealed the following excellent in 805 patients, good in 84 patients, fair in 14 patients and poor in 0. The good quality rate was 98.4%. Conclusion    Novel modified Nuss procedure can simplify and optimize the surgical design with good short and mid-term effects.
