Prolonged air leak after pulmonary resection strongly influences chest tube duration and hospitalization. This prospective study aimed to report a series of experiences with a synthetic sealant (TissuePatch™) and compare them with a combination covering method (polyglycolic acid sheet + fibrin glue) for air leaks after pulmonary surgery.
We included 51 patients (age: 20–89 years) who underwent lung resection. Patients who presented with alveolar air leak during the intraoperative water sealing test were randomly assigned to the TissuePatch™ or combination covering method groups. The chest tube was removed when there was no air leak over a period of 6 h, and no active bleeding under continuous monitoring using a digital drainage system. The chest tube duration was assessed, and various perioperative factors (such as the index of prolonged air leak score) were evaluated.
Twenty (39.2%) patients developed intraoperative air leak; ten patients received TissuePatch™; and one patient who was receiving TissuePatch™ switched to the combination covering method because of broken TissuePatch™. The chest tube duration, index of prolonged air leak score, prolonged air leak, other complications, and postoperative hospitalization in both groups were similar. No TissuePatch™-related adverse events were reported.
Results from the use of TissuePatch™ were almost similar to those associated with the use of combination covering method in preventing prolonged postoperative air leak after pulmonary resection. Randomized, double-arm studies are required to confirm the efficacy of TissuePatch™ observed during this study.
