The treatment of pectus excavatum: Results of a mininvasive surgical technique on the first 50 patients

Description

Aim. Pectus excavatum is the commonest thoracic congenital malformation, but its treatment remains not well known. The authors present the results of the mini-invasive repair at G. Gaslini Institute of Genoa, Italy. Methods. Nuss mini-invasive repair avoids anterior scars. The correction is achieved by the introduction under thoracoscopy of a retrosternal curve bar that is rotated by 180°. Postoperatory pain is managed by an epidural catheter. In all the operated patients we evaluated the clinical pre-operatory parameters (Spirometrie, radiological and cardiological data), the surgical details and the results. Results. Fifty patients were operated, 43 of them males, ranging from 7 and 22 years of age, with an average of 17 years of age. Only 8 of them were asymptomatic and required surgery for psychological reasons. The 74% presented some stress dyspnea. Some impairment in spirometric parameters were observed in 28% and mitral valve prolapse in 30%. The only significant intraoperative complication was a bleeding from a thoracic wall vessel that required a left emergency minimal thoracotomy. Postoperative complications were: 2 pneumothorax (drained for 24 hours), 2 transitory pulmonary atelectasis, 1 hemothorax in a patient with coagulation deficit, 3 wound problems (1 infection and 2 hematomas). The esthetical score after surgery, according to the patients, was 9.15 on average, in a scale from 1 to 10. None rated less than 7. The pain score with the same scale was rated 6.8 on average. Conclusion. The Nuss technique is safe and guarantees very satisfactory esthetical results.
