Surgical treatment of pectus excavatum: 30 years 398 patients of experiences.

PURPOSE: The aim of the study is to review the surgical experiences with pectus excavatum (PE) chest deformities at the Department of Pediatric Surgery, West China Hospital of Sichuan University (Sichuan, PR China), during a 30-year period.

METHOD: Records of 398 PE patients (396 congenital, 2 acquired) who underwent surgical repair between 1975 and 2005 were reviewed. Modified sternal elevation was applied in all patients. Repair was performed with subperiosteal resection of the abnormal cartilages, transverse wedge osteotomy of the anterior sternum, and internal support with a metal strut for 1 year. Five technical details were strictly followed for each case. Three hundred twelve patients (78.39%) were followed up from 1 to 16 years.

RESULT: There were no deaths. Normal contour of the costal cage was constructed postoperatively in 98.74% (393/398) of the patients. Exercise tolerance was improved, and cardiac function recovered to the healthy level of same age. But pulmonary function recovered slowly after surgery.

CONCLUSIONS: The 5 technical details are key principles for sternal elevation. Normal appearance of chest wall can be recovered; normal cardiopulmonary function can be restored by the modified sternal elevation with excellent long-term physiologic, cosmetic results and low rate of complications.
