ABSTRACT

@#The long-term survival and quality of life of liver transplant recipients largely depend on long-term health management and immunosuppression regimen after surgery. Long-term use of immunosuppressants may lead to severe complications, such as kidney injury, metabolic diseases and new malignant tumors, and even increase the risk of liver cancer recurrence after liver transplantation. At present, common immunosuppressive regimens in liver transplant recipients are delivered based on calcineurin inhibitor (CNI). However, renal toxicity, neurotoxicity and increased tumor recurrence caused by CNI have significantly affected clinical prognosis of the recipients. In recent years, the dosage of CNI has been gradually reduced and alternative drugs have been explored. Recently, the use of immunosuppressive regimens based on mammalian target of rapamycin inhibitor (mTORi) has been gradually increased. Multiple domestic and international guidelines have provided guidance on the use of mTORi in liver transplant recipients. China Organ Transplantation Development Foundation organized experienced transplant experts in China, combined with published guidelines, consensus and research progress at home and abroad and solicited extensive opinions to jointly formulate this expert consensus, aiming to provide reference for liver transplant clinicians in China.

ABSTRACT

A widening gap between demand and availability of donor livers for transplantation has stimulated the use of extended-criteria donor(ECD)livers, including donation after circulatory death liver grafts.However, these types of donor livers carry an elevated risk of developing such postoperative complication as ischemic type biliary lesions(ITBL).Although the pathogenesis of ITBL has remained elusive, severity of histological bile duct injury(BDI)at the time of transplantation has been identified as a strong predictor of the development of ITBL post-transplantation.In recent years, significant advances have been achieved in the field of liver machine perfusion.Normothermic machine perfusion(NMP)is primarily utilized for determining the quality of ECD organs.To evaluate the extent of biliary injury during NMP, some reliable criteria of BDI are required.This review focused upon different approaches of assessing damage to biliary tree and current understandings of potential effects of NMP on biliary system and biliary injury.Also it offered an overview of novel biomarkers and emerging therapeutic strategies.

ABSTRACT

Objective:To explore the role of internal stenting for preventing biliary anastomotic complications during complex duct-to-duct biliary reconstruction of orthotopic liver transplantation.Methods:From December 1, 2018 to April 30, 2020, intraductal stent was placed in 6 cases of complex biliary tract reconstruction during liver transplantation. Postoperative prognosis, recovery of bilirubin and biliary enzymes, management of intraductal stent and occurrence of postoperative biliary complications were observed.Results:All of them recovered and were discharged smoothly and bilirubin and biliary enzymes normalized before discharge. The average peak values of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase were 83.8±56.4 μmol/L, 151.5±76.3 U/L, 301.7±177.0 U/L and 98.4±80.9 μmol/L and the average turning points of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase 2.3±1.0, 3.0±1.1, 3.8±1.2 and 1.8±0.8 days; average time of complete recovery of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase 7.7±5.1, 5.0±4.9, 23.5±7.6 and 3.8±2.4 days respectively. Intraductal stent was removed by gastroduodenoscopy ( n=3) and slipped off ( n=3). Except for one case of asymptomatic anastomotic stricture at 1 year post-operation, no biliary complications occurred during follow-ups. Conclusions:The placement of intraductal stent during complex biliary reconstruction of liver transplantation can effectively promote the recovery of postoperative liver function, enhance the quality-of-life of patients, effectively avoid the occurrence of biliary anastomotic complications and ensure the safety of patients.

ABSTRACT

Objective:To explore the clinical evaluation outcomes of COVID-19 risk assessment scale on organ donation and procurement during the pandemic of novel coronavirus pneumonia (NCP) and reduce the incidence of donor-derived infection and medical staff infection.Methods:From January 20 to February 29 in 2020, the organ procurement team adopted the COVID-19 risk assessment scale for evaluating 8 potential donors. They were classified into the levels of high/low/uncertain risk by analyzing the risk levels of donation hospitals, clinical characteristics and exposure history. The coordinators, organ evaluators and ward medical staff adopted essential protective measures. The infection status of 2019-nCoV in the above mentioned staff was examined and graft function in the corresponding recipients were observed.Results:Based upon the COVID-19 risk assessment results, the risk level was high (n=8), low (n=5) and uncertain (n=2) and underwent organ procurement. A total of 19 grafts including liver, kidney, pancreas and heart were harvested and successfully utilized for organ transplantation. During the observation period of 14 days, there was no suspected or confirmed infection of 2019-nCoV among coordinators and medical staff. No graft dysfunction or acute rejection was observed during a follow-up period of 4 to 30 days. No recipient was suspected or confirmed to be infected with 2019-nCoV and 6 of them were negative for 2019-nCoV nucleic acid testing after organ transplantation.Conclusions:During the COVID-19 pandemic, it is safe to proceed with donor organ evaluations and procurements according to the result with the COVID-19 risk assessment scale. Low-risk donor organ donation may be carried out, uncertain risk donor organ donation should be performed cautiously and high-risk donations discouraged.

ABSTRACT

Objective:To investigate the clinical evaluation effects of Corona Virus Disease 2019 (COVID-19) risk assessment scale on preoperative and surgical risk of liver transplantation during the COVID-19 outbreak.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 6 liver transplant recipients who were admitted to Southern Theater Command General Hospital of PLA between January 20 and March 27, 2020 were collected. There were 5 males and 1 female, aged from 42.0 to 62.0 years, with a median age of 53.0 years. There were 6 donors including 5 males and 1 female, aged from 24.0 to 60.0 years, with a median age of 41.5 years. All the donor livers were obtained through the China Organ Transplant Response System. Liver transplantation was performed in the fixed negative pressure operating room, and secondary protective measures were adopted for low-risk donors. Classic orthotopic liver transplantation or Piggyback liver transplantation was performed according to the specific situations of the recipients. Medical staffs in the ward were exposed to the secondary protective measures, and the three-grade protective measures were adopted for medical staffs when the liver transplant recipients had fever or suspected infection. Observation indicators: (1) risk assessment of COVID-19 on liver transplant recipients; (2) risk assessment of COVID-19 on medical staffs of liver transplantation; (3) treatment situations of liver transplant recipients; (4) postoperative situations of liver transplant recipients; (5) follow-up of liver transplant recipients; (6) infection of medical staffs of liver transplantation. Follow-up was performed using outpatient examination or telephone interview to detect whether liver transplant recipients had suspected or confirmed COVID-19 infection up to March 2020. Medical staffs who were involved in organ acquisition, transplantation surgery and ward management were followed up to detect whether they had suspected or confirmed COVID-19 infection within 14 days. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were described as M (range). Count data were expressed as absolute numbers. Results:(1) Risk assessment of COVID-19 on liver transplant recipients: all the 6 recipients and their related families were confirmed no contact with suspected COVID-19 patients or travel history in the epidemic area within 14 days. Of the 6 recipients, 1 was diagnosed with fever with body temperature of 38.1 ℃ and was tested negative for chest computer tomography (CT) examination and nucleic acid test for COVID-19; 1 was diagnosed with fever and hypoxemia with body temperature of 38.5 ℃ and was tested negative for nucleic acid test for COVID-19, and the results of chest CT examination showed large amount of pleural effusion in both lungs without invasive pneumonia; other 4 recipients had no clinical symptoms of COVID-19 with negative results of chest CT examination and nucleic acid test for COVID-19. Five of the 6 recipients had no history of contact with COVID-19 patients and 1 recipient had treatment history at hospital of risk level 1. The preoperative risk level of COVID-19 was low in all the 6 liver transplant recipients. (2) Risk assessment of COVID-19 on medical staffs of liver transplantation: of the 6 recipients, 5 had the waiting hospital of risk level 0 and 1 had the waiting hospital of risk level 1. Six recipients had the transplant hospital of risk level 0. (3) Treatment situations of liver transplant recipients: of the 6 recipients, 2 underwent classic orthotopic liver transplantation and 4 underwent piggyback liver transplantation. The cold ischemia time of liver, time of anhepatic phase, volume of intraoperative blood loss, operation time, treatment time at intensive care unit of the 6 recipients were (5.9±2.4)hours, (49±14)minutes, 1 500 mL(range, 800-1 800 mL), (8.9±2.1)hours, 2 days(range, 1-4 days), respectively. Of the 6 recipients, 2 required adjustment of the immunosuppression program, and 4 did not change the immunosuppression program. (4) Postoperative situations of liver transplant recipients: of the 6 recipients, 5 had no postoperative serious infection and 1 had postoperative serious infection. The 5 recipients without postoperative serious infection had the range of the highest temperature as 37.8-38.5 ℃, and returned to normal temperature within postoperative 3 days. All of the 5 recipients who had no postoperative serious infection received chest CT examination with no obvious manifestation of viral pneumonia and were tested negative for nucleic acid test for COVID-19 at 1 week postoperatively, and then were discharged from hospital. One recipient who had postoperative serious infection had gastrointestinal fistula and repeated fever at postoperative 7 days with the highest temperature as 39.2 ℃. This recipient had body temperature returned to normal and good function of the graft after treatment in the isolation ward with active drainage, and was transferred back to local hospital for further rehabilitation treatment. The duration of hospital stay of the 6 recipients were 30 days(range, 15-74 days). (5) Follow-up of liver transplant recipients: all the 6 recipients were followed up for 31.5 days(range, 12.0-64.0 days) with the normal body temperature, and they had negative results of viral pneumonia for chest CT examination and nucleic acid test for COVID-19. (6) Infection of medical staffs of liver transplantation: surgeons, nurses, anesthetists, medical staffs at ICU and medical staffs at liver transplantation center who participated in liver transplantation had good health within postoperative 14 days, without suspected or confirmed cases of COVID-19 infection.Conclusions:The COVID-19 risk assessment scale has good safety for liver transplant recipients during the COVID-19 outbreak. It is suggested that organ transplantation can be carried out in low-risk recipients and cautiously carried out in recipients of uncertain risk, but organ transplantation should not be carried out in high-risk recipients.

ABSTRACT

The shortage of donor liver is the main factor that restricts the development of liver transplantation and the curative effect of liver transplantation for hepatocellular carcinoma (HCC). Previous studies have focused on the selection criteria of recipient, downstaging therapy, immuno-suppressive therapy, etc. In recent years, it has been found that the selection of donor liver significantly inluence tumor recurrence after liver transplantation. The author discusses the main types of clinical liver donors, criteria of liver transplantation for HCC, selection of donor liver in liver transplantation for HCC within indications, selection of donor liver in liver transplantation for HCC beyond indications, and the influences of donor liver selection on the prognosis of liver transplantation for HCC.

ABSTRACT

OBJECTIVE@#To investigate the causes and clinical features of children with traumatic brain injury (TBI) who need hospitalization or emergency observation.@*METHODS@#A retrospective analysis was performed for the clinical data of 126 children with TBI who were admitted to the emergency department from January 1, 2014 to August 31, 2016, including causes of injury and clinical features.@*RESULTS@#Of the 126 children, there were 95 boys and 31 girls, with a mean age of 2.8 years (range 0.8-5.5 years). The children aged <1 year accounted for 38.1% (48/126), and 26 children died. The two most common types of TBI were epidural hematoma (54.0%) and subarachnoid hemorrhage (50.8%). Of the 126 children, 83 (65.9%) had a Glasgow Coma Scale score of ≤8 within 24 hours after admission. There were different causes of TBI and places where TBI occurred in different age groups. The two leading causes of TBI were falls (51.6%) and road traffic injuries (42.9%). Compared with those in the other age groups, the children in the age <1 year group were most likely to experience injury due to falls (46%; P=0.023). Thirty-five percent of all TBI due to road traffic injuries occurred in the children aged 3-6 years (P<0.001). Most TBI cases occurred at home (47.6%) or on roads/streets (45.2%). Among those who experienced TBI at home, the children aged <1 year accounted for the highest proportion of 48% (P=0.002), and 53% of the patients aged 3-6 years experienced TBI on roads/streets. The most common cause of death in children with TBI was road traffic injury, which accounted for 69%. Among those who died, the children aged <1 year accounted for the highest proportion (62%).@*CONCLUSIONS@#There are different causes of TBI and places where TBI occurs in different age groups. Among children with TBI, the children aged <1 year account for the highest proportion and have the highest number of deaths, with falls at home as the most common cause of TBI. Children aged 3-6 years tend to suffer TBI due to road traffic injury. Road traffic injury is the leading cause of death.

ABSTRACT

Objective To summarize the experiences and protocol of extracorporeal membrane oxygenation (ECMO) technique in donors with brain death and unexpected cardiac arrest.Method We described here the organ donation of one case of brain death complicated with hemodynamic instability and cardiac arrest,and the corresponding recovery of the receptor liver.A 50-year old female developed brain death due to brain aneurysmal hemorrhage.He was given two kinds of high-dose vasopressor,but hemodynarnic instability was not improved.After ECMO support,the hemodynamics turned to stable,but unexpected cardiac arrest happened.The total operating time of ECMO was 5 h,including 4 h after cardiac arrest.The liver was transplanted into a 65-year old female with hepatocellular carcinoma (diagnosed by Hangzhou Criteria) by classic orthotopic liver transplantation with end-to-end anastomosis.Result One liver and two kidneys were obtained successfully,and all the receptors recovered uneventfully.The post-operative ALT and AST levels reached the peak at 169 U/L and 365 U/L respectively,and returned to normal two weeks later.Conclusion ECMO can be used to support brain death complicated with hemodynamic instability and unexpected cardiac arrest.It can save precious time for organ donation,and preserve the function of liver and kidney as well.
