Pectus excavatum is a congenital chest wall deformity, commonly identified in early childhood, creating a "sunken chest" appearance. Over time, the deformity can worsen, thus impacting cardiopulmonary function and creating significant body image disturbance in patients. The Nuss procedure is a minimally invasive technique in which a curved steel bar is introduced underneath the sternum through small bilateral thoracic incisions to correct the deformity. Most studies regarding the procedure to date focus on outcomes and complications in pediatric patients, however, few studies discuss these results in adult patients. This systematic review aims to analyze common complications and outcomes in patients over the age of 18 who have not undergone any prior intervention for pectus excavatum. The most common complications experienced in adult patients were displacement of the implanted steel bar, infection of the surgical site, pneumothorax, pleural effusion, and chronic postoperative pain. Reoperation was common in patients with a displacement of the bar, chronic pain, and bleeding. Additionally, adult patients routinely required a higher number of steel bars to be placed to correct the deformity. Despite evidence that the rate of complications increases with age, the majority of adult patients in our included studies were satisfied with the outcome of the procedure with indications of improved self-image and reduced preoperative symptoms such as dyspnea on exertion, palpitations, chest pain, and depression.
