Professor Gyu-Seong Choi's research lab specializes in advanced laparoscopic and robotic liver surgery, with a strong focus on improving surgical outcomes in living donor liver transplantation and anatomical liver resection. The lab investigates surgical techniques, vascular and biliary anatomy variations, and their impact on complications and long-term graft survival. Key research directions include optimizing the transition from open to laparoscopic surgery, evaluating the feasibility of laparoscopic right hemihepatectomy in complex anatomical variants, and comparing surgical approaches like 'cut and clip' versus 'clip and cut' for biliary integrity. The lab also emphasizes oncological outcomes in hepatocellular carcinoma, particularly in the context of minimally invasive liver resection.
Figures are computed from collected data and may differ slightly.
In the initial 91 pure LLDRH cases, incidence of major complication was higher than in the OLDRH group, but the difference was not significant in propensity-matched analysis. A right hepatic duct verified as <1 cm may be related to increased frequency of complications in pure LLDRH donors. Further analysis is needed.
This study was designed to review laparoscopic living donor liver transplantations (LDLTs) at a single center that achieved complete transition from open surgery to laparoscopy. LDLTs performed from January 2013 to July 2021 were reviewed. Comparisons between open and laparoscopic surgeries were performed according to periods divided into initial, transition, and complete transition periods. A total of 775 LDLTs, 506 laparoscopic and 269 open cases, were performed. Complete transition was achiev
This study is designed to analyze the feasibility of laparoscopic living donor right hemihepatectomy in living donors with portal vein variation. Living donor liver transplantation cases using a right liver graft during the period of January 2014 to September 2019 were included. Computed tomographic angiographies of the donor were 3-dimensionally reconstructed, and the anatomical variation of the portal vein was classified. To reduce selection bias, a 1:1 ratio propensity score-matched analysis
The "cut and clip" technique showed superior outcomes to the "clip and cut" technique in terms of fewer bile duct openings and biliary stricture-free survival of the recipients.
<b><i>Aim:</i></b> There is no evidence indicating that survival improvement is associated with anatomical laparoscopic liver resection (ALLR) rather than non-ALLR (NALLR) to treat solitary hepatocellular carcinoma (HCC). The aim of our study was to compare the oncological outcomes of ALLR versus NALLR. <b><i>Materials and Methods:</i></b> From January 2008 to September 2014, 231 patients underwent LLR as the primary treatment for solitary HCC without portal vein tumor thrombus.
