Da Vinci surgical system-assisted precise hepatectomy / 中华消化外科杂志

ABSTRACT

Objective To assess the feasibility,safety and advantages of robotic-assisted precise hepatectomy.Methods Between April and July 2009,13 consecutive patients underwent robotic-assisted hepatectomy for hepatic diseases.The clinical data were analyzed retrospectively.Results All 13 Da Vinci surgical systemassisted precise hepatectomies were successfully performed without conversion to laparotomy.Major hepatectomies were performed in 9 patients,left lateral segmentectomies in 4 patients.All the Da Vinci surgical system-assisted hepatectomies were performed anatomically with hilum dissection.Prior to the parenchymal transaction,vascular control of the portal vessels was carried out whenever possible.The mean operative time was 338 minutes(range,150-720 minutes).The mean blood loss was 208 ml(range,50-800 ml).No patient required blood transfusion,and no mortality,transient bile leakage was observed in patients with hilar cholangiocarcinoma.The mean postoperative stay was 7 days(range,2-13 days).Conclusions These preliminary results show that Da Vinci surgical system-assisted precise hepatectomy is safe and feasible with potential benefits of a minimally invasive approach.Da Vinci surgical system may broaden the indications for laparoscopic hepatactomy,and it enables surgeons to perform precise laparoscopic hepatectomy which required hilum dissection,hepatocaval dissection,endoscopic suturing and microanastamosis.
