Objective To report the authors' experience with adult living donor liver t
ransplantation (ALDLT) without venovenous bypass and to describe modificati
ons that will allow for a direct duct-to-duct biliary reconstruction.
Summary Background Data Adult living donor liver transplantation is being e
valuated as a method to alleviate the organ shortage. Descriptions of the p
rocedure have emphasized the use of venovenous bypass, portocaval decompres
sion, and the mandatory use of a Roux-en-Y biliary enteric anastomosis. The
authors describe a technique for ALDLT without venovenous bypass, portocav
al decompression, or caval clamping in 11 recipients and describe the modif
ications to the procedure that may allow a duct-to-duct biliary reconstruct
ion in certain cases.
Methods Between March 1999 and March 2000, 11 ALDLTs were performed at the
authors' institution. All procedures were performed without venovenous bypa
ss, portocaval decompression, or caval clamping. After a modification to th
e procedure, five of the last six recipients underwent biliary reconstructi
on with a direct duct-to-duct anastomosis. Data regarding donor, recipient,
and graft survival, complications, and graft function were collected.
Results Recipients comprised five women and six men, mean age 48 years. Don
ors comprised five women and six men, mean age 36.5 years. Donor to recipie
nt relationships included sibling, spouse, son, and daughter. Indications f
or transplantation were hepatitis C, hepatitis C with hepatocellular carcin
oma, primary biliary cirrhosis, primary sclerosing cholangitis, ethanol, an
d cryptogenic. No case required venovenous bypass or portocaval shunting. T
he right hepatic vein of the donor graft was anastomosed to the confluence
of the left and middle hepatic veins in all cases, All donors are alive and
well, with no adverse complications reported. Recipient and graft survival
rates were 91% and 82%, respectively, for ALDLT versus 92% and 92% for rec
ipients of cadaveric organs during the same time period. One recipient died
of multiple organ failure and sepsis. Biliary reconstruction was performed
by Roux-en-Y hepaticojejunostomy in the six cases. In five of the last six
recipients, direct duct-to-duct biliary reconstruction with a T tube was u
sed. No anastomotic leaks or strictures occurred in the patients undergoing
duct-to-duct reconstruction.
Conclusions Adult living donor liver transplantation can be performed safel
y and may help alleviate the organ shortage. Neither venovenous bypass nor
portocaval shunting is necessary to perform the procedure, and modification
s to both the donor and recipient hepatectomy procedures may allow biliary
reconstruction to be performed by a direct duct-to-duct anastomosis in sele
cted cases.
