Objective: Although pectus excavatum repair has evolved to a minimally invasive technique in prepubescent patients, the best approach in adults is less clearly understood. The aim of this study was to identify the preoperative characteristics, operative variables, and postoperative outcomes in adult patients with pectus excavatum undergoing thoracoscopic repair using different bar stabilizers compared with the open surgical repair.
Methods: We conducted a prospective study between July 2009 and July 2012 in a single institution. Thirty-one patients (26 men and 5 women) aged 18 to 35 years were randomly assigned into three groups: group A, 9 patients underwent modified Ravitch repair; group B, 11 patients underwent video-assisted thoracoscopic repair using metal stabilizers; and group C, 11 patients underwent video-assisted thoracoscopic repair using absorbable stabilizers. Preoperative, intraoperative, and postoperative variables are compared between all groups.
Results: In all groups, the preoperative variables were well matched for age, sex, and Haller index. Operative time was 2 hours longer in group A (P = 0.0001). There was no intraoperative complication. Length of hospital stay was 4 days shorter in group A. Morbidity was 23% and composed of pneumothorax (three), wound seroma (two), pleural effusion (one), and stabilizer break (one), occurring more frequently in groups B and C. There was no perioperative mortality. All patients were satisfied with the cosmetic results.
Conclusions: Repair of pectus excavatum in adult patients can be performed effectively through either open surgical technique or thoracoscopy, with no intraoperative complications and with excellent immediate results. Although the operative time for the Ravitch repair was longer, the hospital stay was significantly shorter than that for the video-assisted method.
