Surgical sealant using free pericardial fat pad with fibrin glue and polyglycolic acid sheets for secondary spontaneous pneumothorax: a novel technique.

We report on the "Triple-FP technique," a novel surgical approach for secondary spontaneous pneumothoraces, which combines a free pericardial fat pad, fibrin glue, and polyglycolic acid sheets. In our experience with 13 patients suffering from secondary spontaneous pneumothoraces, this method effectively prevented postoperative air leaks and re-operations. The technique includes the following steps: (1) harvesting free pericardial fat; (2) suturing around the lung parenchymal defect with the needles and thread left outside the thoracic cavity; (3) ensuring contact between the mediastinal pleural side of the fat and the lung; (4) applying fibrin glue to both the lung and fat before suturing; (5) securing the fat to the lung via the suture thread, reinforced with fibrin glue; and (6) stabilization with polyglycolic acid sheets and additional fibrin glue. This innovative technique is a reliable and effective treatment strategy for secondary spontaneous pneumothoraces, especially for patients with fragile lung tissue.
