【目的】探讨 LigaSure 在犬肠道闭合手术中的应用价值。【方法】随机将20只犬分为使用 Li-gaSure 进行肠道闭合术的实验组和使用传统手工肠道闭合术的对照组,根据其闭合的部位不同再将实验组和对照组分为小肠和大肠两个亚组,每组5只。比较两组肠道闭合时间、术中出血量、术后并发症发生率及闭合处肠道的组织结果的变化。【结果】试验组肠道闭合时间小肠为3 s,大肠7 s；对照组肠道闭合时间小肠为(8±2.2)min,大肠为(12±1.2)min。试验组小肠和大肠术中无明显出血(出血量为0 mL),对照组术中出血量小肠为(27±2.86)mL,大肠为(29.65±3.24)mL。上述指标两组间比较差异均具有统计学意义(P 0.05)。【结论】LigaSure 闭合肠道效果可靠,能减少手术时间、肠道闭合时间及术中出血量,且未见明显术后并发症,值得临床进一步研究。“,”Objective]To explore the clinical value of LigaSure in the intestinal closer in dogs.[Methods]Twenty dogs were randomly divided into the experimental and the control group.Dogs in the experimental group were performed on using LigaSure while dogs in the control group were performed on with traditional manual gut closure.According to intestinal different parts,these two groups were then further subdivided into two small subgroups each:intestinal and large bowel (n=5 ).The gut closure time,intraoperative bleeding volume,postoperative complications,and intestinal histological effect were compared between two groups.[Results]The gut closure times of the experimental and control groups were 3 s VS (8 ± 2.2 )min in the small intestine and 7 s VS (12 ± 1.2)min in the large bowel,respectively.The amount of bleeding,0 ml VS (27 ± 2.86)mL in the small intestine and 0 mL VS (29.65 ± 3.24)mL in the large bowel,of the experimen-tal and control groups respectively,were statistically different (P 0.05).[Conclusion]LigaSure on intestinal surgery closure is reliable;it can reduce the bleeding volume,operation time and intraoperative intestinal closure time and its postoperative complications were not found.It is worthy of further clinical research.
