器械与丝线缝合支气管和肺动静脉的比较研究

目的 对器械与手工缝合支气管残端和肺动、静脉方法的优缺点进行评价。方法 24条杂种健康成年犬均分2组行左全肺切除。器械组的主支气管残端和肺动、静脉用缝合器缝合；缝线组用丝线按常规手术方法缝合或结扎。术后分别在3、7、15、30d处死动物。对支气管和肺动、静脉残端进行大体和光镜观察，并对犬的生活质量进行观察。结果 缝线粗支气管残端炎细胞浸润明显高于器械组（P＜0．05）。器械组动、静脉无血栓形成，而缝线组有3条犬在肺动、静脉残端处发现小的血栓。结论 器械缝合提高了手术的窀生和规范化，能减少术后并发症。

Comparitive exprimental study of staplers versus sutures for closing bronchus and pulmonary vessels

Objective: To compare staples with sutures for closing bronchi and pulmonary vessels. Methods: Twenty four dogs were randomly divided into two groups and performed a left pneumoctomy. Left main bronchus and pulmonary artery and vein were closed with staplers in 12 dogs, sutures in another 12 dogs. All dogs were killed at 3, 7, 15 and 30 postoperative day, respectively. General condition of the dogs, specimens of bronchial and vessel stump were observed with microscopy. Results: Infiltration of inflammatory cells were heavier in suture group than stapler group (P<0 05). Microthrombus was found on vessel stumps of 3 dogs in suture group, but no that was observed in stapler group. Conclusion: Stapler can increase the safety of pneumoctomy and make it standardization. It is possible to decrease postoperative complications.
