title: [Preservation of pulmonary function by chest wall reconstruction].
abstract: Thirteen mongrel dogs were resected 4 ribs with surrounding tissue. Eight dogs had the chest wall closed by skin alone, and in five animals, the chest wall reconstructed by a polyethylene mesh or marlex sandwich. In the latter PaO2 was significantly higher than that of animals not undergoing reconstruction 3 days after operation. Pulmonary function was appeared to be preserved by reconstruction. Clinically, 68 cases underwent chest wall resection and in 28 cases, defects were reconstructed. Although only portions of 1 or 2 ribs were resected in the non-reconstructed cases, VC, FEV1, and TLC significantly dropped post-operatively. In the reconstructed cases, VC significantly dropped postoperatively. Post-operative complications occurred in 3.6% of the reconstructed cases and in 9.8% of the non-reconstructed cases. Since only 1 rib resection led to reduced ventilatory function clinically, reconstruction for small chest wall defects appears advisable for maintaining pulmonary function.
