Pectus excavatum (PE) is a congenital chest wall deformity characterized by an inward depression of the lower and middle parts of the sternum and its adjacent ribs. This can cause problems with appearance and, in some cases, with function, like less lung capacity, heart compression, and limits on exercise. Patients presenting with these manifestations may be considered for pectus excavatum surgery.
When Surgery Is Suggested
In cases where patients and their families have a desire for treatment, surgery is the best way to correct moderate to severe PE. Candidates are individuals with significant chest wall depression, dyspnea, or psychological distress due to their appearance. Early assessment and surgical intervention, especially in early childhood, can help improve outcomes and reduce risks.
Wang Procedure: A Less Invasive Choice
Dr. Wenlin Wang developed the Wang procedure in 2018. It is a minimally invasive way to do surgery for pectus excavatum. The Wang procedure differs from the traditional Nuss procedure in that it places the steel bar on the surface of the depressed bony structure. Steel wires are threaded through the sternum and rib cartilages to lift the chest wall that has sunk in, and the midsection of the bar is secured to the sternum. This method does not enter the chest cavity, which avoids the risk of heart damage and lets bones grow normally. It is safe for children under five years old.
Results and Recovery
Patients who undergo the Wang procedure usually get a stable, long-lasting correction outcome, and the risk of deformity recurrence is lower after puberty. Recovery is usually quicker and less painful than other methods. The Wang procedure effectively addresses the physical and psychological effects of PE by restoring the chest wall’s appearance and function.
In short, the Wang procedure is a safe and effective option for treating PE, especially when early intervention is taken into account. The technique is recognized and performed by specialists at The Institute of Chest Wall Surgery (ICWS), providing a reliable surgical solution for eligible candidates.
