Abstract

Pectus excavatum (PE) represents the most prevalent congenital deformity of the chest wall, and minimally invasive repair of pectus excavatum (MIRPE) continues to evolve in pursuit of improved correction and reduced morbidity. Both cross-bar (CB) and parallel-bar (PB) configurations are widely adopted, yet comparative data remain limited. This systematic review and meta-analysis evaluated perioperative outcomes and postoperative efficacy of CB versus PB techniques.
