The objectives of this study were to validate the 2.0 mm Endo GIA stapler for lung lobectomies and to compare procedural time and air leakage incidence with suture ligation. Sixteen canine cadavers, 18 to 27 kg, were randomly assigned to undergo lung lobectomy of the right middle lung lobe through intercostal thoracotomy, after which suture ligation or the 2.0 mm Endo GIA stapler was used. Procedural time was recorded. Following the lobectomy, the thoracic cavity was filled with fluid. Positive pressure ventilation was used to hold pressure at 20 cm HO for 5 minutes. The bronchus was assessed for air leakage as evidenced by visualization of gas bubbles and the ability to maintain positive pressure. Procedural time and air leakage incidence were compared between groups. By these assessments, the 2.0 mm Endo GIA stapler was successful for lung lobectomies in all cadavers. There was no significant difference (t = -0.856, = 0.407) in body weight by procedure assignment. Procedural time was significantly shorter ( < 0.0001) using the Endo GIA stapler compared to suture ligation. There was no significant correlation ( = 0.044, = 0.873) between body weight and procedural time. There were no incidents of air leakage in either group. The 2.0 mm Endo GIA stapler may be used as an alternative device for lung lobectomies in canine cadavers. Smaller staples may provide more complete compression of hilar vessels and bronchi, resulting in reduced hemorrhage, air leakage, and thoracic contamination in cases with infection or neoplasia.
本研究的目的是验证 2.0mm Endo GIA 吻合器用于肺叶切除术，并比较其与缝线结扎的手术时间和漏气发生率。16 只 18 至 27 公斤重的犬尸体随机分为两组，通过肋间开胸行右中叶肺叶切除术，然后使用缝线结扎或 2.0mm Endo GIA 吻合器。记录手术时间。肺叶切除术后，胸腔内充满液体。使用正压通气在 20cmHO 下保持压力 5 分钟。评估支气管有无漏气，表现为可见气泡和维持正压的能力。比较两组之间的手术时间和漏气发生率。通过这些评估，所有尸体的 2.0mm Endo GIA 吻合器均成功用于肺叶切除术。手术分配时体重无显著差异（t=-0.856，=0.407）。与缝线结扎相比，使用 Endo GIA 吻合器的手术时间明显缩短（<0.0001）。体重与手术时间之间无显著相关性（=0.044，=0.873）。两组均无漏气事件。2.0mm Endo GIA 吻合器可作为犬尸体肺叶切除术的替代装置。较小的吻合钉可能会更完全地压迫肺门血管和支气管，从而减少出血、漏气和感染或肿瘤病例的胸腔污染。
