摘要
目的：通过动物试验改进腹腔镜加压吻合器在胃肠吻合中的应用方法并观察其效果。方法：在犬上消化道吻合手术中,采用腹腔镜加压吻合器操作指导及改进后的手术操作步骤两种不同的方法实施吻合,根据手术录像记录每一吻合操作的各步骤时间及动作次数等数据,通过实际操作及统计分析对比两种吻合方法,并在术后不同时间处死动物,行吻合口处病理切片检查以观察吻合效果。结果：采用改进后的吻合方法无吻合口漏发生,较原吻合方法在实际操作时更加简便可靠,平均置入吻合夹时间减少32%,尝试次数减少66%,无效操作减少74%,缝合操作孔针数减少39%；术后2周吻合口处浆膜愈合完整,肌层及粘膜下层纤维增生,粘膜已覆盖吻合口。结论：腹腔镜加压吻合器在胃肠吻合中采取改进的吻合方法效果更佳,术后2周可形成光滑完整的吻合口。
Objective：To improve the surgical techniques in the application of laparoscopic compression anastomosis clip（LapCAC）divice for gastrointestinal anastomosis in a canine model and evaluate the efficacy.Methods：Using LapCAC for upper GI procedures in a canine model,operations were ferformed according to the LapCAC operation guide and the modified procedure,in order to find the better way through practices and statistics based on the video record of the operations.The snimals were sacrificed at intervals after the operations and stained sections of the tissue at the anastomotic site were made for evaluation.Results：According to the modified procedure,anastomoses were performed more simply and reliably without leaks,the time for introduction of the clip were decrased by 32%,and for suture incisions 39%,times of attempts 66%,inefficiency 74%,Complete reepithelialization of the mucosa and chorion at the anastomotic site occur in 2 weeks after the operation ,Conclusions The modified procedure is better than the operation guide,a smooth homogenized anastomosis will form in 2 weeks after the operation.
