Summary: This study assessed the safety of modified Nuss procedures for severe pectus excavatum. The results showed that the modified Nuss procedure with slanting steel bar insertion is a safe and effective approach for correcting severe pectus excavatum, with no occurrences of heart, pericardium, or lung injuries during the surgeries.

Summary: The modified Nuss procedure using a new titanium alloy bar can achieve good outcomes for adult patients with recurrent pectus excavatum. After the operation, the Haller index significantly decreases, and there is a low rate of postoperative complications.

Summary: This study retrospectively analyzed data from 259 patients with pectus excavatum who were treated with modified Nuss procedure between August 2020 and August 2021. The results showed that the modified Nuss procedure had optimistic outcomes with minimal invasion and low complication rate. It can be potentially applied to other hospitals in the future.

Summary: This study evaluated the learning process of consecutive Nuss procedures and found that after a proctoring period of 10 procedures, repair of pectus excavatum by the Nuss procedure is a safe surgery to adopt, with at least one procedure performed every 35 days.

Summary: This study aimed to investigate the longitudinal changes in pulmonary functions of adolescents with Pectus Excavatum who underwent the minimally invasive repair of pectus excavatum (MIRPE), known as the Nuss procedure. The results showed that shortly after implantation of the bar, there was a decline in vital capacity, forced vital capacity, and forced expiratory volume in 1 second. However, after bar explantation, these values significantly increased. Additionally, airway resistance parameters also showed similar changes.

Summary: The purpose of this study is to propose a new in silico Nuss procedure that can predict the outcomes of chest wall deformity correction. A 3D geometric and finite element model of the chest wall was built from a CT image of a 15-year-old male patient with mild pectus excavatum. Simulations of anterior translating the metal bar and maintaining equilibrium after a 180-degree rotation were performed. A simulation with the chest wall finite element model and intercostal muscles was also conducted. The results of the REM simulation were found to be most similar to the actual patient's outcomes. By comparing clinical and mechanical indicators with postoperative patients, the authors conclude that the REM simulation of the in silico Nuss procedure proposed in this study best simulates the actual surgery.

Summary: Limited data exists on the outcomes of the Nuss procedure for pectus excavatum repair in adults. This study analyzed changes in lung capacity and thoracic morphology in adult patients before, during, and after the Nuss procedure, showing decreased lung capacity but improved chest shape post-surgery. Although lung capacity did not significantly increase, surgical modifications may help reduce thoracic spine stress and improve patient comfort. Long-term observation is necessary for further evaluation.

Summary: This study reviewed the clinical data of pediatric patients with pectus excavatum and compared the clinical outcomes of the Modified bar bending method with the traditional bar bending method. The results showed that the Modified bar bending method significantly reduced procedure duration, bar bending time, and duration of postoperative pain, while also reducing the incidence of bar migration. There were no significant differences in postoperative effect evaluation, postoperative complications, and operative safety compared to the traditional method.

Summary: This study evaluated the safety and efficacy of a modified single incision non-thoracoscopic Nuss procedure in children with pectus excavatum (PE). The results showed that the modified procedure reduced operation time, postoperative inpatient stay, and blood loss compared to the traditional procedure. Additionally, the procedure led to a significant decrease in Haller index after bar removal.

Summary: This study revealed that postoperative lung volumes and function in adult pectus excavatum patients decreased significantly after Nuss procedure. Diaphragm elevation was positively associated with decrease in lung volumes, and reduced thoracic anteroposterior diameters were significantly associated with negative pulmonary function results.

Summary: A novel hybrid biodegradable Nuss bar model was developed for correcting chest deformities and reducing pain. The model showed promising results in an animal model and demonstrated good biocompatibility with animal tissues. It may have potential applications in treating chest deformities in humans.

Summary: Primary spontaneous pneumothorax often occurs in tall and thin individuals without underlying diseases or trauma, and patients with pectus excavatum have higher chances of developing primary pneumothorax. The Nuss procedure, used to correct pectus excavatum, can result in bilateral tension pneumothoraxes if pneumothorax occurs after the surgery.

Summary: This study is a prospective, multicenter, non-masked, randomized controlled trial that evaluates the outcome and hospitalization medical expense of single incision Non-thoracoscopic Nuss Procedure (SINTNP) compared to thoracoscopic assistance Nuss Procedure (TNP) for pectus excavatum (PE). 320 eligible patients aged 3 to 18 years old without complex anomalies will be randomly assigned to either the SINTNP group or the TNP group. The primary endpoints are thoracic related complications and medical expense during hospitalization.

Summary: This retrospective study investigated the paths of thoracic epidural catheters in children. The study found that the catheters advanced straight for the first 2-3 cm in the thoracic epidural space, but after that, the paths became unpredictable. Catheters with straight paths were located at higher levels compared to those with curved or coiled paths.
