Pectus excavatum: abordagem terapêutica

The pectus excavatum treatment has two different approaches: non-surgical techniques (modified dynamic thoracic compressor, exercises and the vacuum bell) or surgical techniques (silastic or solid silicone implant, open surgical repair like sternochondroplasty and minimally invasive repair). The introduction of Nuss procedure improved the pectus excavatum treatment, but its low acceptance was due to the high complication rate (e.g. cardiac perfuration). The thoracoscopy use for bar mediastinal passage reduced the complication rate. In comparison with sternochondroplasty, the Nuss procedure has smaller incision, less blood loss and less operative time. However, it has more reoperations, complications, longer hospital stay and more readmission rates, more time of thoracic epidural catheter for postoperative analgesia and more need for analgesic after being discharged. Although Nuss procedure has been used in children, patients under ten years must be only observed. The Nuss procedure is applicable to moderate or light symmetrical pectus excavatum, without costal protrusion, in young and adolescents patients. Furthermore, the sternochondroplasty is applicable to severe or asymmetric pectus excavatum, with or without inferior costal protrusion. Therefore, Nuss procedure and sternocondroplasty are not antagonistic procedures, and they must be used in accordance with a treatment organogram and the technique choice must be by functional and aesthetic outcome.
