Reoperation after the failure of Wang procedure on pectus excavatum: Wung procedure + Wenlin procedure

Wang procedure for pectus excavatum is a simple and safe surgery. However, improper operation may lead to failure of the surgery. We received a 7-year-old male patient with pectus excavatum who failed Wang procedure. We used the combination of Wung procedure and Wenlin procedure to correct the deformity and achieved satisfactory results.
