Koo‐Jeong Kang, Jae Hwi Jang, Tae Jin Lim, Yuna Kang, Kwan Kyu Park, In Seon Lee, Pierre‐Alain Clavien – 20 May 2004 – We designed this experimental study to determine the optimal cycle for intermittent inflow occlusion during liver resection. A cycle of intermittent clamping (IC) for 15 minutes of ischemia followed by reperfusion for 5 minutes during liver resection is currently the most popular protocol used by experienced liver centers. As each period of reperfusion is associated with bleeding, longer periods of clamping would be advantageous.

Hiroshi Imamura, Norihiko Kokudo, Yasuhiko Sugawara, Keiji Sano, Jun‐ichi Kaneko, Tadatoshi Takayama, Masatoshi Makuuchi – 20 May 2004 – While inflow occlusion techniques such as Pringle's maneuver are accepted methods of reducing bleeding without inducing liver injury during liver surgery, donor hepatectomy for living donor liver transplantation is currently performed without inflow occlusion for fear that injury to the graft may result.

Zhen Fan Yang, Tung Yu Tsui, David W. Ho, Terence C. Tang, Sheung‐Tat Fan – 20 May 2004 – This study aims to clarify the role of heme oxygenase‐1 (HO‐1) in small‐for‐size liver transplantation. Transplantation was performed using 40% small‐for‐size or 100% whole liver grafts in rats. When no treatment was given, over‐expression of HO‐1 was detected predominantly in the small‐for‐size grafts at 6 hours after reperfusion as compared to whole grafts in both syngeneic and allogeneic combinations.

DeokBog Moon, SungGyu Lee, Shin Hwang, KwangMin Park, KiHun Kim, ChulSoo Ahn, YoungJoo Lee, TaeYong Ha, SeongHun Cho, KiBong Oh, YeonDae Kim, KeonKuk Kim – 20 May 2004 – We considered performing living donor liver transplantation (LDLT) in a larger‐size recipient. When the recipient was large‐sized, or when the donor liver was severely steatotic or had a right‐to‐left volume discrepancy. We devised dual living donor liver transplantation (DLDLT) to make up for graft size insufficiency and to secure the donor's safety.

Yasutsugu Takada, Mikiko Ueda, Yukika Ishikawa, Yasuhiro Fujimoto, Hideaki Miyauchi, Yasuhiro Ogura, Takenori Ochiai, Koichi Tanaka – 20 May 2004 – In the development of adult‐to‐adult living donor liver transplantation (LDLT), the small‐for‐size graft has been associated with poor clinical outcome. Persistent portal hypertension or portal venous overperfusion are considered to be causative factors, and partial diversion of portal flow to systemic circulation may be effective for avoiding injuries that occur in the small‐for‐size (SFS) graft.

Norihito Ise, Tsutomu Sato, Ouki Yasui, Go Watanabe, Kenji Koyama, Kunihiko Terada, Toshihiro Sugiyama, Yuzo Yamamoto – 20 May 2004 – It is known that hepatic progenitor cells increase in number after liver injury caused by carcinogens, but this injury cannot be reproduced in humans. In order to create a practical source of hepatic progenitor cells, changes in the number of liver epithelial cells (LECs), a type of hepatic progenitor cell, were examined following partial interruption of the portal flow.

Shin Hwang, Sung‐Gyu Lee, Kwang‐Min Park, Ki‐Hun Kim, Chul‐Soo Ahn, Young‐Joo Lee, Kyu‐Bo Sung, Deok‐Bog Moon, Tae‐Yong Ha, Sung‐Hun Cho, Ki‐Bong Oh, Ji‐Min Han, Myung‐Hwan Kim – 20 May 2004 – Hepatic venous congestion (HVC) has not been assessed quantitatively prior to hepatectomy and its resolving mechanism has not been fully analyzed. We devised and verified a new method to predict HVC, in which HVC was estimated from delineation of middle hepatic vein (MHV) tributaries in computed tomography (CT) images.

Chi Leung Liu, Sheung Tat Fan, Chung Mau Lo, See Ching Chan, Irene O. Ng, Ching Lung Lai, John Wong – 20 May 2004 – A prospective evaluation was performed to study the potential benefits of the use of interleukin‐2 receptor antibody (IL‐2Rab) in the induction therapy with early elimination of steroid and reduction of tacrolimus dosage in liver transplant recipients among whom 94% had chronic hepatitis B infection.
