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.
