Abstract
Objective To evaluate the efficacy of laparoscopic Habib 4X (Habib 4X,Angio Dynamics US),a new bipolar radiofrequency (RF) device,in laparoscopic liver resection.Methods Thirty one patients who underwent laparoscopic liver resection using the laparoscopic Habib 4X from Sept 2009 to Apr 2012 were studied retrospectively.Results The laparoscopic Habib 4X was success fully used in 30 patients (malignant,n=18; benign,n=12).The procedures performed included left lateral sectionectomy (n=12),left hemi-hepatectomy (n=1),Ⅴ or Ⅵ segmentectomy (n=9),Ⅴ and Ⅵ bi-segmentectomy (n=2) and wedge exclusion (n=6).The time required for precoagulation and resection was 10～68 min (median 24 min).The mean intraoperative blood loss was 145±75ml (range 8-370 ml).Mild abnormal liver function which returned to normal in 3 to 5 days was detected postoperatively.The mean hospital stay was 7.8±2.6 d (range 3～12 days).There was no patient who developed postoperative bleeding,bile leakage or abdominal abscess.For cancer patients,there was no local recurrence on follow-up.Conclusion Laparoscopic Habib 4X,a device when used in laparoscopic liver resection,resulted in minimal blood loss and quick recovery.It had only mild effect on liver function and it had low morbidity.In addition,it might reduce the risk of local recurrence in malignant tumours. Key words: Laparoscopic liver resection; Habib 4X; Blood loss
