The utility of buttressing an endoscopic mechanical stapler with strips of bovine pericardium in resection of pulmonary bullous areas was evaluated by comparing the duration of air leakage in two randomized patient groups, one with and one without buttressing. The duration of air leakage was not related to bulla size in either group but showed a linear relation with the radiologic emphysema score in both groups (p < 0.001) and was shorter when the stapler had been fitted with bovine pericardium, but significantly reduced (p = 0.019) only in patients with a high emphysema score. The duration of air leakage was thus related to emphysema score, and in patients with high scores was shortened by application of bovine pericardium to the stapler.
通过比较两组随机分组患者（一组使用牛心包条带支撑内镜机械吻合器切除肺大疱区域，另一组不使用支撑）的漏气持续时间，评估了牛心包条带支撑内镜机械吻合器在肺大疱区域切除中的效用。两组患者的漏气持续时间均与肺大疱大小无关，但与两组的放射学肺气肿评分均呈线性关系（p < 0.001），并且当吻合器安装牛心包时漏气持续时间较短，但仅在肺气肿评分高的患者中显著缩短（p = 0.019）。因此，漏气持续时间与肺气肿评分有关，在评分高的患者中，将牛心包应用于吻合器可缩短漏气持续时间。
