Tracheal anastomoses are known to be related to special surgical risks. We performed laser-assisted trachea anastomoses in 10 Beagle dogs, using an Argon-laser system and a handheld quarz fiber for energy transmission. All animals showed an uneventful postoperative course without signs of infection, air-leakage or respiratory impairment. Pathologic examination revealed no significant stenosis but a normal reconstruction of the tracheal endothelium and a normal woundhealing with only an increased connective tissue reaction. Because of the lower tensile strength of laser-assisted anastomoses in general, three adapting absorbable sutures should be left in situ to increase the resistance against mechanical stress. Under these circumstances laser-assisted anastomoses seem to be a promising additional method in the field of tracheal reconstruction and transplantation.
已知气管吻合术与特殊的手术风险相关。我们使用氩激光系统和用于能量传输的手持式石英纤维，对10只比格犬进行了激光辅助气管吻合术。所有动物术后过程平稳，无感染、漏气或呼吸功能受损的迹象。病理检查显示无明显狭窄，气管内皮正常重建，伤口愈合正常，仅结缔组织反应增强。由于一般情况下激光辅助吻合术的抗张强度较低，应留置三根可吸收的适配缝线以增加抗机械应力的能力。在这种情况下，激光辅助吻合术似乎是气管重建和移植领域一种有前景的辅助方法。
