超声刀与多功能手术解剖器在肝切除术中的应用疗效及安全性对比

Comparison of Curative Effect and Safety Between Ultrasonic Scalpel and Multifunctional Surgical Dissector in Liver Resection Surgery

目的分析超声刀与PMOD(彭氏多功能手术解剖器)在解剖性肝切除手术中的应用疗效及安全性对比。方法选取进行腹腔镜下解剖性肝切除手术患者72例,以手术操作器械的不同分为对照组和观察组,每组36例。对照组于腹腔镜下置入超声刀,观察组于腹腔镜下置入改良的彭氏多功能手术解剖器(PMOD)。比较两组肝门阻断时间、术中出血量及手术时间。结果对照组的肝门阻断时间和手术时间长于观察组,对照组的术中出血量少于观察组,组间差异有统计意义(P<0.05)。结论超声刀与PMOD对于解剖性肝切除手术的应用疗效及安全性均较好,能提高预后。相对来说,超声刀对于止血、离断肝组织和管道的效果更好,可以减少出血;PMOD不用频繁更换手术器械,缩短手术时间和肝门离断时间。

Objective To analyze and compare curative effect and safety of ultrasound knife and PMOD(Peng's multifunctional surgical dissector)in anatomical liver resection surgery.Methods The paper chose 72 patients with laparoscopic anatomical liver resection surgery,and divided them into control group and observation group based on different surgical instruments,with 36 cases in each group.Control group was treated with ultrasound knife under laparoscopy,and observation group with improved Peng's multifunctional surgical dissector(PMOD)under laparoscopy.Time of hepatic portal occlusion,intraoperative bleeding volume,and surgical time was compared between two groups.Results Hepatic portal occlusion time and surgical time in control group was longer than observation group,intraoperative blood loss in control group was lower than observation group,with statistical significance(P<0.05).Conclusion Both ultrasonic scalpel and PMOD can achieve good effect and safety in anatomical liver resection surgery,improve prognosis.Relatively speaking,ultrasound scalpel is more effective in stopping bleeding,cutting off liver tissue and pipelines,and can reduce bleeding.PMOD does not require frequent replacement of surgical instruments,and can reduce surgical time and hepatic portal detachment time.
