Which procedure is a modern minimally invasive repair for Pectus excavatum?

• A. Nuss procedure
• B. Ravitch operation
• C. Laparoscopic fundoplication
• D. Thoracentesis

Answer: (A)

The main idea here is how pectus excavatum is repaired using a modern minimally invasive approach. The Nuss procedure achieves this by placing a curved steel bar under the sternum through small lateral chest wall incisions. The bar acts like a wedge, pushing the sternum outward and correcting the sunken chest without a large chest wall reconstruction. After placement, the bar stays in place for a couple of years to allow the chest to remodel, and then it is removed. This minimally invasive method contrasts with the Ravitch operation, which is more invasive and involves resection of deformed cartilage and sternal osteotomy to reshape the chest. The other two options are unrelated: laparoscopic fundoplication treats gastroesophageal reflux, and thoracentesis drains pleural fluid. So the modern minimally invasive repair is the Nuss procedure.
