Abstract
INTRODUCTION: Intraoperative alveolar air leaks remain a significant problem in thoracoscopic surgery (TS) cases. We examined the usefulness of covering damaged lung tissue with a subcutaneous fat pad for preventing postoperative air leakage in patients with non-small cell lung cancer (NSCLC). METHODS: Patients with NSCLC underwent a thoracoscopic lobectomy or segmentectomy. When alveolar air leakage from the superficial pulmonary parenchyma was found, fibrin glue in combination with an absorbable mesh sheet was applied (S group; n = 100). When leakage originated from deep within the pulmonary parenchyma, a subcutaneous fat pad about 2 × 2 cm in size was harvested from the utility incision and placed on the damaged lung tissue with fibrin glue and sutures (F group; n = 66). Patient characteristics, air leak duration, and chest-tube removal time were analyzed. RESULTS: The homogeneity of each group was consistent, with no statistical differences for age, respiratory function, surgical procedures, pathologic stage, and histological type. The air leak duration was significantly shorter (p = 0.015), and the chest tube was removed significantly earlier (p = 0.002) in patients in the F group. CONCLUSION: Use of a free subcutaneous fat pad during pulmonary resection for TS patients with NSCLC reduced the duration of air leakage and chest tube drainage. The present method is easy, safe, and effective for repairing an air leak from remaining lung tissues in such cases.
