AIM： To estimate the standard liver weight for assessing adequacies of graft size in live donor liver transplantation and remnant liver in major hepatectomy for cancer. METHODS： In this study, anthropometric data of body weight and body height were tested for a correlation with liver weight in 159 live liver donors who underwent donor right hepatectomy including the middle hepatic vein. Liver weights were calculated from the right lobe graft weight obtained at the back table, divided by the proportion of the right lobe on the computed tomography. RESULTS： The subjects, all chinese, had a mean age of 35.8 ± 10.5 years, and a female to male ratio of 118：41. The mean volume of the right lobe was 710.14 ±131.46 mL and occupied 64.55%±4.47% of the whole liver on computed tomography. Right lobe weighed 598.90±117.39 g and the estimated liver weight was 927.54 ± 168.78 g. When body weight and body height were subjected to multiple stepwise linear regression analysis, body height was found to be insignificant. Females of the same body weight had a slightly lower liver weight. A formula based on body weight and gender was derived： Estimated standard liver weight （g）=218＋BW （kg）× 12.3＋gender×51 （R^2 = 0.48）（female=0, male= 1）. Based on the anthropometric data of these 159 subjects, liver weights were calculated using previously published formulae derived from studies on Caucasian, .lapanese, Korean, and chinese. All formulae overestimated liver weights compared to this formula. The Japanese formula overestimated the estimated standard liver weight （ESLW） for adults less than 60 ***： A formula applicable to chinese males and females is available. A formula for individual races appears necessary.

ABSTRACT: Fulminant hepatic failure is a medical emer-gency. When this condition declared itself irreversible, atimely liver transplantation is the only effective treatment.A 34-year-old chinese with fulminant hepatic failure wasevaluated as a potential liver transplantation candidate. Onthe erect chest radiograph, chilaiditi' s sign has developedover a very short period of a week due to rapid shrinkage ofthe liver. Awareness of chilaiditi' s sign facilitated distin-guishing the condition of free gas under the diaphragm dueto bowel perforation and subphrenic abscess by gas formingmicro-organisms. Rapidity of onset of this sign parallels thedeterioration of liver function and reflects the urgency ofcondition.

Surgical resection with a tumor-free margin is the onlycurative treatment for hilar cholangiocarcinoma (Klatskin tumor). However, over half of the patients present late with unresectable tumors. Radiotherapy using external beamirradiation or intraluminal brachytherapy (ILBT) has been used to treat unresectable hilar cholangiocarcinoma with satisfactory outcome. We reported a patient with unresectable hilar cholangiocarcinoma surviving more than 6 years after combined external beam irradiation and ILBT.

Versatility and viability of hepatic venoplasty in live donor liver transplantation using the right lobe with the middle hepatic vein

引用

Hepatobiliary & Pancreatic Diseases International 2005年第4期4卷 618-621页

作者： See-ching Chan Chung-Mau Lo chi-leung liu Yik Wong Sheung-Tat Fan Centre for the Study of Liver Disease and Departments of Surgery The University of Hong KongPokfulamHong KongChina Radiology The University of Hong Kong PokfulamHong KongPokfulamHong KongChina

Including the middle hepatic vein in the right lobe liver graft has the advantage of providing direct venous drainage of the right anterior segment. To allow unimpeded passage of blood flow, we previously designed venoplasty of the middle and right hepatic veins. We found that venoplasty is also feasible when the inferior right hepatic vein is near to the right hepatic vein, or when multiple segment 8 hepatic vein orifices are exposed adjacent to the middle hepatic vein at the graft transection surface. By joining the hepatic vein orifices into a single opening, the anastomosis into the inferior vena cava is much facilitated. The technique is simple, yet versatile , and able to cope with variation of the configurations of the hepatic vein.

Hepatobiliary & Pancreatic Diseases International 2002年第2期1卷 166-171页

作者： Sheung-Tat Fan Chung-Mau Lo chi-leung liu From the Centre for the Study of Liver Disease and Department of Surgery, University of Hong Kong Medical Centre, Queen Mary Hospital, Hong Kong, china Centre for the Study of Liver Disease and Department of Surgery University of Hong Kong Medical Centre Queen Mary Hospital Hong Kong China. hrmsfst@hkucc.hku.hk

Objective: To review the experience of donor selec- tion and right lobe hepatectomy in adult-to-adult live donor liver transplantation. Methods: From May 1996 to December 2001, 89 live donor liver transplants using right lobe grafts were performed at Queen Mary Hospital, Hong Kong. All donors had received psychological counseling before donor operations. They were screened by laboratory tests including complete blood cell count, liver and renal biochemistry, and viral serology studies. Com- puted tomography (CT), CT volumetry and hepatic arteriography were routinely performed. All donors underwent the operations using the method designed by us. Results: The median duration of the operations was 8.8 hours. The median blood loss recorded 466 ml. The median intensive care unit and hospital stays were 2 and 10 days, respectively. There was no do- nor mortality. Complications of donor operations in- cluded wound infection, urinary tract infection, bili- ary stricture, cholestasis, subphrenic collection, bowel obstruction and incision hernia, etc. All do- nors have recovered and returned to their previous occupations. Conclusions: Live donation of right lobe grafts for a- dult-to-adult liver transplantation is safe, provided that donor selection is strict and utmost care is exer- cised during the operation.

Effect of pouring time on microstructure and mechanical properties of centrifugal cast Ti-46Al alloy tubes

引用

china Foundry 2025年

作者： Gang Huang Qian Dang Cong-cong Su Jing Zhao chi Zhang Guo-huai liu Zhao-dong Wang The State Key Laboratory of Rolling and Automation Northeastern University School of Materials Science and Engineering Shenyang University of Technology

The grain size of TiAl alloy castings prepared by traditional casting process is coarse, thus showing poor mechanical properties. In this study, a new type of high performance Ti-46Al alloy tube prepared by vacuum centrifugal casting technology was introduced. This research comprehensively examined the influence of pouring time on the microstructure and mechanical performance of the castings, employing both experimental approaches and ProCast simulation methodologies. The findings indicate that prolonging the pouring time facilitates a microstructural evolution from coarse columnar grains to refined equiaxed grains. Under the condition of pouring temperature of 1,600 °C, rotation speed of 800 r·min-1and pouring time of 6 s, the tensile strength of Ti-46Al alloy at room temperature reaches 650 MPa, and the tensile strength at 800 °C reaches 705 MPa, which is significantly higher than that of traditional as-cast Ti-Al alloy.
