Is Lung Ultrasound the Technique of Choice for the Diagnosis of Pneumothorax Following the Nuss Procedure for Pectus Excavatum?
This study will be conducted to determine the advantages and limitations of sonography compared with chest radiography, in the detection of post procedure iatrogenic pneumothorax in patients underwent to Pectus Excavatum (PE) with Nuss repair.
The Nuss procedure is a minimally invasive technique for the repair of Pectus Excavatum (MIRPE).
Residual pneumothorax (PNX) is reported in more than 50% after Nuss procedure. It is a consequence of the introduction of the scope and bar in the pleural space and is considered a minor complication due to the minimal clinical consequences. It is routine practice to confirm the diagnosis of PNX with a conventional chest X-Ray either in the operating room at the end of thoracic surgery or in the recovery room unit immediately after surgery.However, anterior pneumothorax can occur and chest-X ray could not be able to detected the PNX. Nowadays lung ultrasound (LUS) allows a bedside non-invasive evaluation of the patient(with a sensitivity and specificity of 92 and 99% respectively) without exposure to ionized radiation, can be performed more quickly than chest radiography and therefore can be repeated several times without additional risks. The use of LUS in pediatric age groups is more recent, but is becoming widely utilized both in neonatal and pediatric respiratory diseases.
Bedside sonography for diagnosis of PNX has been well described in emergency and trauma medicine literature and it is resulted to be more sensitive and specific than portable anteroposterior chest radiography. Although there are few studies describing the use of ultrasound for the detection of surgical pneumothorax, none of them studied its use after Nuss Procedure.
