Hepatectomy By Using Bipolar Radiofrequency Excision Hemostatic Device Habib^TM4X

Objective:To investigate the application effect of bipolar radiofrequency resection hemostasis device HabibTM4X in liver resection surgery.Methods:A restrospective study was performed during February2013to February2015,71patients accepted the operations of liver resection, according to the operation method is divided into Habib group (n=22)and the control group(n=49). Compared to the latter, The former holding a disposable radiofrequency ablation device HabibTM4X vertically into the liver, cut along the desired route. Energy generated by a controlled amount of RF energy between the electrodes will be closed in the liver tissue, including the bile duct and blood vessels, and then use the scalpel for liver resection. Intraoperative blood loss, blood transfusion, Recovery of liver function, postoperative complications, Postoperative stay, survival rate, mortality were recorded. Results:.The patients accepted HabibTM4X:The procedures performed included left lateral sectionectomy (n=3),VI segmentectomy (n=1),VI and VII bi-segmentectomy (n=1) and wedge exclusion (n=17). The mean operation time was177±75min(range92-364min); The mean intraoperative blood loss was182±164ml(range50-650ml); The mean recovery of postoperative liver function time was7±3days(range2-15days);2cases of patients with ascites or pleural effusion; Postoperative stay range5-15days, the mean time was10±3days.The control group:The procedures performed included The right liver resection(n=2), Left liver resection(n=1), left lateral sectionectomy (n=1),VI segmentectomy (n=2), Ⅵ and Ⅶ bi-segmentectomy (n=1) and wedge exclusion (n=42). The mean operation time was330±106min(range166-597min); The mean intraoperative blood loss was629±595ml(range50-3000ml); The mean recovery of postoperative liver function time was9±3days(range3-15days);25cases of patients with ascites or pleural effusion, postoperative transfusion therapy for17patients; Postoperative stay range5-43days, the mean time was14±7days.Habib group’s average operation time was significantly reduced, statistically significant difference (P<0.05); Habib group’s average intraoperative blood loss was significantly less than the control group(P<0.05); Habib group’s average recovery time of postoperative liver enzyme faster than the control group (P<0.05); The incidence of postoperative complications shows Habib group was obviously less than control group(P<0.05); the postoperative blood transfusion rate shows Habib group was obviously less than control group (P<0.05); Habib group’s average hospitalization period was shorter than the control group (P<0.05), the differences were statistically significant.Conclusions:The premise of strictly selected indications for surgery, liver resection by Habib TM4X is safe and reliable; can shorten the operation time, produce positive effects on control of intraoperative bleeding, reducing the influence on liver function, effectively avoid the common postoperative complications. Bipolar radiofrequency resection hemostasis device HabibTM4X could be a choice as liver resection technology.
