Chest wall reconstruction using a new titanium mesh: a multicenter experience.

Background: Many new surgical techniques and materials have been introduced in the last decade for chest wall reconstruction or stabilization with the purpose of improving the incorporation, maintaining chest wall stability with reduction of infections. However, none of them are yet considered a gold standard procedure. The aim of this work is to evaluate the initial experience using a new titanium mesh for chest wall reconstruction in four Italian Thoracic Surgery Departments. Methods: A review was performed of all patients undergoing chest wall reconstruction using a new titanium mesh between January 2014 and September 2018. Surgical indications, the location and size of the chest wall defect, intraoperative variables and postoperative complications were analyzed. Results: A total of 26 consecutive patients were included. The most common indications for surgery were primary or secondary chest wall tumors (38%) followed by lung cancer invading chest wall (31%). The most common localization of chest wall defect was anterolateral (46%). Sternal reconstruction was required in 3 patients (12%). The average size of the defect was 9.3×7.8 cm. The median number of resected ribs was 3.6. No perioperative deaths occurred. Mean hospital stay was 11.9 days. Overall morbidity was 19%. One failure of reconstruction (4%) was reported during follow up. Conclusions: In our early clinical experience chest wall reconstruction using titanium mesh can be performed as a safe and effective surgical procedure. This mesh has excellent biomechanical characteristics between rigid and malleable materials, it's easy to trim and fix for optimal adaptation without necessity of dedicated instruments. The early and mid-term results are satisfactory with low incidence of complications related to the titanium mesh implant.
