Since the robotic surgical system was first
launched in 2005, the number of robotic surgery has been gradually growing in
Korea. The proportion of general robotic surgery is relatively higher than the
western countries, but robotic liver resection, especially living donor right
hepatectomy is one of the most complex procedures among robotic general
surgery. Since its introduction in 1994, living-donor liver transplantation
(LDTL) was the standard treatment for both hepatocellular carcinoma and for
patients with the end-stage liver disease. Our hospital started robotic living
donor program in 2016. Since then, more than 70 cases of robotic living donor
hepatectomy have been successfully performed.
In this video, we introduce our current
standardized procedure of robotic living donor right hepatectomy from hilum
dissection, parenchymal transection, bile duct division to caudate lobe
transection, also the ligation of vessels. In addition, we explain how to
manage unexpected events during robotic surgery and our journey to expand the
indication of donors from favorable to unfavorable anatomy.

Background: Pure laparoscopic donor hepatectomy (PLDH) has become accepted surgical procedure in living donor liver transplantation (LDLT). This study aimed to report our initial experience and outcomes of PLDH and to compare with conventional open donor hepatectomy (DH).
Methods: The medical records of 1175 consecutive (12/ 2011 - 12/2019) live liver donors at our center were retrospectively reviewed. To minimize selection bias, donors who underwent DH after the initiation of the PLDH program were excluded.
Results: 24 donors underwent PLDH. The total operation time (510 minutes [IQR 410-710] vs. 315 minutes [IQR 285-350]; P< 0.05) and time to remove the liver (405 minutes [IQR 360-576] vs. 262 minutes [IQR 242-305]; P< 0.05) were longer in PLDH. The warm ischemic time (11 minutes [interquartile range (IQR) 10-18] vs. 3 minutes [ IQR 2-7]; P< 0.05) was also longer in the PLDH group than the DH group. The length of postoperative hospital stay was shorter in the PLDH group (6 days [IQR 6-8] vs. 7 days [IQR 7-9]). There was no difference in postoperative complications among donors or recipients in both groups.
Conclusions: PLDH is feasible and can be performed safely as DH at an experienced LDLT center. Further analysis including long-term outcome is needed

we present few cases of robotic donor right hepatectomies where we burnt our
four main difficulties we faced during the robotic donor hepatectomies were
- This results in excessive force on the liver during retraction
causing capsular tears and parenchymal injuries.
- Performing Intraoperative cholangiogram during robotic surgery is
cumbersome and time consuming. Limitations of MR cholangiogram can lead to
unexpected multiple ducts in the graft , perhaps causing biliary catastrophe in
donors and recipients.
- This is the most common cause for conversion to open. Bleeding can be from
IVC, Portal Vein, Hepatic Veins and Parenchyma. Clip slippages are not uncommon
and can cause catastrophic bleed. In case of bleeding coordination among
console surgeon, assistant surgeon, anesthesia and nursing paramedical team is
shouldn't be any hurry during retrieval. Minimal increase in warm ischemia will
not make any harm. Following a check list and mock drills will make retrieval
smooth as well as safe for both the donor and the graft.
trust this video will help surgeons performing or venturing into the field of
robotic donor hepatectomy.
|VT02-07 ||Combined Right Middle Hepatic Vein Single Orifice Outflow Reconstruction in Modified Right Lobe Live Donor Liver Transplant

modified right lobe graft, middle hepatic vein is preserved with the donor. To
avoid anterior sector congestion in the recipient a neo-Middle Hepatic Vein (MHV)
is routinely reconstructed. We hereby report our technique.
During donor hepatectomy, inferior hepatic
veins & venous tributaries of
segment 5(V5) and segment 8(V8) larger than 5 mm are preserved for reconstruction
with good cuff. Good cuff of right hepatic vein(RHV) is also ensured. Non-ringed
expanded (e)-Polytetrafluoroethylene (PTFE) graft is used for creating
Neo-MHV. The segment 8 vein is anastomosed in end to side manner& segment 5
in end to end manner to PTFE. The anterior wall of RHV at middle 1/3rd and
posterior half circumference of e-PTFE graft are joined to create a single
outflow orifice. RHV and
neo-MHV single outflow orifice is implanted onto the IVC using a side clamp,
instead of fencing. The suprahepatic IVC is mobilized and a side clamp was
applied on the IVC at RHV orifice. RHV opening is enlarged cranially up and caudally on to the
cava to make it about 2.5x as that of graft RHV opening. The posterior wall of
the single orifice is anastomosed to approximately 80% of the posterior wall of
the IVC opening. The rest of the posterior and whole of the anterior wall is
then anastomosed to the anterior wall of the combined single orifice to
accommodate the extra length and thus to create a triangular outflow. Inferior
vein is separately reconstructed to IVC.
