Objective:To review our experience in the use of "Full right-Full left" split liver transplantation in adult-to adult or adult-to adult-size child.Methods:The clinical data of liver donors to 4 recipients of full right-full left split liver transplantation performed at Beijing Friendship Hospital of Capital Medical University from January to December 2019 were reviewed. The surgical methods of split liver transplantation, cold ischemia time, operation time, intraoperative blood transfusion, and postoperative complications and prognosis were analyzed.Results:The 4 recipients of complete right hepatic-left hepatic split liver transplantation included 3 adults and 1 heavy child (45 kg). Their ages ranged from 14 to 48 years, and body weight ranged from 45 to 61 kg. The end-stage liver disease model score were 21, 12, 41, and 30 points. The ratios of graft mass to recipient's body mass ranged from 0.85% to 1.35%. The cold ischemia time was 457-650 min, and the operation time was 460-575 min. Early liver function recovered smoothly in all the 4 patients after transplantation, and no small liver syndrome occurred. Patients were followed up to 6 months after operation. One patient developed anastomotic biliary leak, which was cured by endoscopic retrograde cholangiopancreatographic treatment. Another patient developed biliary stricture presenting with repeated biliary tract infection despite percutaneous transhepatic puncture biliary drainage. A third patient died six months from lung infection.Conclusion:In properly selected patients, using full right-full left hemiliver by split liver transplantation increased organ utilization and provided patients with increased treatment opportunities.

BACKGROUND:Stability of the support surface and visual input are important factors affecting static balance,but most of the studies on the balance ability of elderly with mild cognitive impairment have focused on the stable hard support surface,and the control of static balance on the unstable support surface under different visual input conditions is not known. OBJECTIVE:To investigate the static balance ability of the elderly with mild cognitive impairment on soft and hard support surfaces under different visual input conditions. METHODS:Twenty-one elderly people with mild cognitive impairment and nineteen elderly people with normal cognition were selected for the study,and the Kistler three-dimensional dynamometer was used to conduct four tests:standing with two feet on hard support surface with eyes open,standing with two feet on soft support surface with eyes open,standing with two feet on hard support surface with eyes closed,standing with two feet on soft support surface with eyes closed,and standing with two feet on soft support surface with eyes closed,and the duration of each test was 30 seconds.The plantar center of pressure data were collected and compared between the two groups under different visual conditions on the soft and hard support surfaces. RESULTS AND CONCLUSION:(1)Under the condition of visual input,the total excursions(soft support surface:P=0.003),the total excursions-medial-lateral sides(soft support surface:P=0.001,hard support surface:P<0.001)and the 95%confidence ellipse area(soft support surface:P=0.001,hard support surface:P<0.001)of the center of pressure in the elderly with mild cognitive impairment on the soft and hard support surfaces were significantly higher than those of the elderly with normal cognition.(2)In the absence of visual input,the root mean square distance(P=0.014),the root mean square distance-medial-lateral sides(P=0.014),and the 95%confidence ellipse area(P=0.001)of center of pressure in the elderly with mild cognitive impairment on the soft support surfaces were significantly higher than those of the elderly with normal cognition,but there were no significant differences between the groups on the hard support surface(P>0.05).(3)These findings confirm that compared with the elderly with normal cognition who could make full use of visual sensory input to maintain body balance on the soft and hard support surfaces,mild cognitive impairment elderly presented a deficit in balance function.In particular,mild cognitive impairment elderly relied more on ankle proprioception to maintain balance when visual interference was present,suggesting that mild cognitive impairment elderly should focus on strengthening ankle proprioceptive training.

Hepatocellular carcinoma is one of the common malignant tumors in China, which seriously threatens the life and health of the nation. Hepatic vein tumor thrombosis (HVTT) is one of the common clinical manifestations. The prognosis of hepatocellular carcinoma combined with HVTT is extremely poor, and there is no unanimous opinion on its treatment in China and abroad. Currently, Asian guidelines recommend multidisciplinary treatment for patients with vascular invasion. This article reviewed the current progress in the treatment of hepatocellular carcinoma combined with HVTT.

Objective:To explore the clinical feasibility and efficacy of using donated liver procured from donors complicated with intra-peritoneal widespread dissecting aneurysm.Methods:One case of liver donation was assigned to our center from COTRS. Intra-peritoneal widespread dissecting aneurysm was detected intraoperatively with an involvement of coeliac trunk until artery superior to bifercation of HA (hepatic artery). HA reconstruction was extremely challenging. With the final attempt of using donors artery next to hilus lienis as a bridge vessel, success of reconstruction was achieved.Results:During an early postoperative period, satisfactory graft blood flow was established without surgical complications, the patient was discharged smoothly. At Month 13, blood flow of graft remained decent.Conclusions:Through a review of the relevant articles, a few cases have been successful using of donated liver from donors with intra-peritoneal dissecting aneurysm as long as proper hepatic artery is not involved and the difficulty of HA reconstruction remains relatively low. As for widespread intra-peritoneal dissecting aneurysm, donor liver should be employed cautiously.

Hepatic alveolar echinococcosis is a zoonotic parasitic disease caused by echinococcus multilocularis infection. The growth pattern of the lesions of hepatic alveolar echinococcosis is similar to that of liver malignant tumor showing invasive growth. Hepatic alveolar echinococcosis can not only directly invade the adjacent tissue structure, but also metastasize through the lymphatic tracts and blood vessels. Hepatic alveolar echinococcosis with intraperitoneal implantable metastasis is extremely rare. The authors introduce the diagnosis and treatment of 1 patient who had hepatic alveolar echinococcosis with intraperitoneal implantable metastasis.
