Minimally Invasive Repair of Pectus Excavatum in Adult Patients

Abstract

Since 1996, the technique for minimally invasive repair of pectus excavatum (MIRPE) has gained increasing acceptance among pediatric patients. However, the feasibility of the operation and outcomes have not yet been evaluated in adult patients. This study was a retrospective analysis of the author's experience combined with a survey of members of the American Pediatric Surgical Association in treating adult patients with MIRPE. Thirty adults (age range, 18-32 years; mean, 23 years; 75% men) with severe pectus excavatum (chest index > 3.2) were treated with MIRPE. The main indication for surgery was cosmetic (80%). One 32-year-old female patient underwent simultaneous MIRPE and breast augmentation. In 60 per cent of cases, the operative time was 1 to 2 hours. Thoracic epidural was successfully used for postoperative pain management in 90 per cent of patients. Two pectus bars were necessary in 16 per cent of cases, and bilateral stabilizers were used in 53 per cent of patients. Complications included seroma (10%), bar displacement (6%), pneumothorax requiring tube thoracostomy (6%), superficial wound infection (3%), and stabilizer bar fracture (3%). Two patients required conversion to modified Ravitch repair. Patient satisfaction was rated as excellent (50%), good (36%), and fair (14%). Less than 50 per cent of patients achieved 100 per cent correction of their deformity. MIRPE can be used safely for repair of pectus excavatum in adult patients. The complication rate appears to be similar to previously reported series of pediatric patients. Although adult patients may have residual asymmetry of the chest postrepair, overall satisfaction with the repair was very good or excellent in 86 per cent of patients.
