Ten year experience of bioabsorbable mesh support in pectus excavatums repair

Introduction. We reviewed 10 years experience in the treatment of this deformity using a retro-sternal bioabsorbable mesh in place of a metallic device to lift and stabilise the sternum. Moreover, the mesh supports the thoracic and upper abdominal wall reconstruction. Materials and methods. From January 1990 to December 2000, in our Thoracic Surgery Unit, 65 patients with PE were assessed for surgical repair, mean age 16 ± 3.5 years, fronto sagittal thoracic index (FSTI) 0.21, ranging from 0.15-0.33. Twenty-three of them underwent surgical correction after initial assessment, 22 were deferred and sent to physiotherapy. At a subsequent assessment, five of the patients sent to physiotherapy were deemed to require surgery. Results. Of the 28 patients who underwent surgery, 2 (10%) presented a mild recurrence of PE after 1 year (0.30 < FSTI > 0.34), meanwhile all other patients maintained a FSTI >0.34. For all patients the improvement in FSTI was statistically significant, p=0.001. Patients satisfaction after 24 months was thus shared: excellent 18 patients (65%), good seven patients (25%), fair one patient (3.5%) and poor two patients (7%). No major complications were observed in preoperative period. Patients mobilisation was soon achieved thanks to the postoperative pain control and the absence of retro-sternal metallic support. Conclusions. The introduction of bioabsorbable mesh in the Robicsek technique is a safe procedure related to a high percentage of success. The high tolerance of the material reduces the inflammatory reaction. Moreover, the procedure prevents patients from having complications caused by retro-sternal devicef dislodgment, avoiding a second intervention for device reposition and reducing the postoperative chest pain achieving an early patient mobilisation. In the end a complete reconstruction of the upper abdomen wall has been produced. © 2004 The British Association of Plastic Surgeons. Published by Elsevier Ltd. All rights reserved.
