Nuss procedure for the correction of pectus excavatum in children without thoracoscopy / 中华胸心血管外科杂志

ABSTRACT

Objective The aim of this study was to evaluate the efficacy and safety of the approach of the Nuss procedure for the correction of pectus excavatum in children without thoracoscopy.Methods From Oct 2007 and May 2009,48 patients with pectus excavatum underwent Nuss procedure.Among them 22 were done under the thoracoscopic guidance,and the other 26 in a non-thoracoscopic way,in which,a bilateral extrapleural tunnel to the edge of sternum was created using a blunt dissection via a bilateral thoracic skin incision.Without introducing the thoracoscopy into the thoracic cavity,a steel bar was inserted in the entirely extrapleural tunnel and turned as the standard Nuss procedure.Results All 48 patients recovered uneventfully.There were no postoperative deaths and serious complications.A single alloy steel bar(23-40 cm)was used in all patients.In the non-video-assisted extrapleural group(n=26),no pneumothorax occurred,the operating time(after anesthesia)ranged from 24～38 minutes[mean(25.4±2.6)mins],blood loss was minimal(range,5-10 ml),and the hospital stay was ranged from 3-6 days[mean(4.5±1.1)days].In the thoracoscopic group(n=22),the corresponding figures were 40 to 60 minutes[mean(53.5±3.4)mins)],10 to 15ml,5-8days[mean(7.0±2.2)days],respectively.No recurrent of the funnel chest occurred during the 3-18 months(median 10.4 monthes)of follow-up.The bar displacement occurred in 1 case 2 months after operation,which was replaced with satisfied result.Conclusion The non-thoracoscopic approach of the Nuss procedure is a safe and less traumatic procedure for the correction of pectus excavatum.
