BACKGROUND: Prolonged air leak is the major limiting factor in early hospital discharge following pulmonary resection. The purpose of this study was to determine whether the use of bovine pericardial strips as a buttress along the lung staple line would decrease air leaks and hospital stay after lobectomy and segmentectomy. METHODS: This was a multicenter trial consisting of 80 patients undergoing pulmonary resection, randomly assigned to the control group (40 patients) or treatment group (40 patients). The treatment group had reinforcement with bovine pericardium. RESULTS: No statistical differences were noted in the mean intensive care unit length of stay (p = 0.9), number of days with a chest tube (p = 0.6), or total length of stay (p = 0.24). Increased air leak duration was associated with assignment to the control group (r = 0.27, p = 0.02). The mean duration of air leak was 2 days and the mean time to chest tube removal was 5.9 days in patients with a buttressed staple line compared to 3 days and 6.3 days, respectively, for patients with nonbuttressed staple lines. CONCLUSIONS: Within the data of this study, no statistical differences were noted between buttressed and nonbuttressed patients. However, the trend toward shortened air leak time and tube removal time was apparent in the buttressed group. With greater number of patients studied, it is likely that the cost of bovine pericardium would be justified by shorter air leak duration and hospitalization.
