Three-dimensional reconstruction and virtual hepatectomy for laparoscopic precise liver resection of right liver tumor

Abstract

Objective To evaluate the clinical value of three-dimensional reconstruction and virtual hepatectomy for laparoscopic precise liver resection of right liver tumor. Methods 31 cases of right liver tumor from June 2012 to October 2015 at Department of Hepatobiliary Surgery in Affiliated Hospital of Nantong University, were analyzed retrospectively. Patients were divided into three dimensional reconstruction group (n=15) and control group (n=16), Operation time, bleeding volume during operation, postoperative complications and days of hospitalization after operation in two groups were observed. Results All operation was successfully performed with pure laparoscopic right liver tumor resection in three dimensional reconstruction group. In control group, 1 case was completed by hand-assisted laparoscopic liver resection, 1 case was converted to open operation, the remaining 14 cases underwent total laparoscopic right liver tumor resection. Operation time in 3-dimensional reconstruction group was (141±36)min vs. (207±66)min in control group, bleeding volume was (274±88)ml vs.(418±189)ml, hospitalization after operation was (9±3)days vs.(13±6)days (all P<0.05). Conclusions Preoperative three-dimensional reconstruction and virtual hepatectomy can ensure the localization of parenchyma tumor during the laparoscopic precise liver resection, clarifing the relationship between tumor operation section and peritumoral vascular or biliary ducts, fulfilling the idea of precise liver resection.
