Objective To systematically review the influencing factors of postoperative delirium in liver transplant recipients,providing a basis for future clinical intervention studies.Methods Literature were searched on the influencing factors of postoperative delirium in liver transplant recipients published in the China Biology Medicine disc(CBM),Wanfang Data,China National Knowledge Infrastructure(CNKI),VIP Information,PubMed,Cochrane Library,CINAHL,Web of Science and EMBASE databases from their inception to February 28,2025.The influencing factors of postoperative delirium were extracted and analyzed in liver transplant recipients.Results A total of 12 articles were included.The influencing factors of postoperative delirium in liver transplant recipients included patient factors(body mass index,history of preoperative alcohol abuse,history of infection within 2 months before surgery,preoperative hepatic encephalopathy,proportion of preoperative macrovesicular steatosis,preoperative model for end-stage liver disease score,acute physiology and chronic health evaluation II score,preoperative blood ammonia,preoperative total bilirubin,preoperative serum creatinine),surgical factors(long anhepatic period during surgery),treatment factors(perioperative medication use,prolonged intubation time,use of donation after cardiac death grafts),and postoperative related factors(elevated postoperative aspartate aminotransferase,postoperative sepsis,use of postoperative immunosuppressive drugs).Conclusions Postoperative delirium in liver transplant recipients is influenced by multiple factors.A multidimensional assessment and preventive strategy are required.Future research need focus on dynamic monitoring and personalized intervention plans of postoperative delirium.

In recent years, with the development of organ preservation, surgical techniques, perioperative management and immunosuppression regimens, the success rate of liver transplantation and survival rate of the recipients have been significantly enhanced. Liver transplantation has become the optimal treatment for patients with end-stage liver disease. However, biliary complications still commonly occur after liver transplantation, especially biliary anastomotic stricture. Severe biliary anastomotic stricture will not only increase the cost of treatment, but also lead to graft loss and even affect the survival rate of recipients. Therefore, timely diagnosis and treatment of biliary anastomotic stricture play a significant role in improving the survival rate of liver transplant recipients. In this article, the risk factors, clinical symptoms, diagnosis and treatment of biliary anastomotic stricture after liver transplantation were reviewed, aiming to provide novel ideas for the research, diagnosis and treatment of biliary anastomotic stricture after liver transplantation, and further enhance clinical efficacy of liver transplantation and the quality of life of recipients.

Objective To systematically review the effectiveness of perioperative oral probiotics in hepatic resection patients,and provide evidence-based clinical evidence.Methods PubMed,Cochrane Library,Web of Science,EMbase,SinoMed,WanFang Data,CNKI and VIP databases were electronically searched to collect randomized controlled trials(RCTs)on perioperative oral probiotics in hepatectomized patients from inception to June 30,2023.Two reviewers independently screened literature,extracted data and assessed the risk of bias of the included studies.Meta-analysis was performed by RevMan 5.4 software.Results A total of 10 RCTs were included,including 715 patients.The Meta-analysis showed that compared to placebo or blank controls,the incidence of postoperative infections in oral probiotic patients(RR=0.60,95％CI 0.48 to 0.74,P＜0.001),serum endotoxin levels(MD=-0.88,95％CI-1.53 to-0.22,P=0.009),cumulative antibiotic use(MD=-1.48,95％CI-2.17 to-0.78,P＜0.001),AST levels(MD=-9.68,95％CI-11.36 to-8.01,P＜0.001),ALT levels(MD=-21.24,95％CI-34.81 to-7.68,P=0.002),TBiL levels(SMD=-0.70,95％CI-0.95 to-0.45,P＜0.001),CRP levels(SMD=-0.52,95％CI-0.91 to-0.13,P=0.009),procalcitonin levels(MD=-0.19,95％CI-0.32 to-0.05,P=0.006),IL-6 levels(MD=-7.30,95％CI-14.26 to-0.33,P=0.04),and the first flatus time(MD=-1.16,95％CI-1.51 to-0.82,P＜0.001),hospital stay(MD=-0.62,95％CI-0.83 to-0.41,P＜0.001),hospitalisation costs(SMD=-0.65,95％CI-0.95 to-0.34,P＜0.001)were lower.Conclusion Current evidence shows that perioperative oral probiotics can significantly reduce the postoperative infection rate and decrease the release of inflammatory factors in liver resection patients,promote the recovery of postoperative hepatic and gastrointestinal functions,and shorten the length of hospital stay and costs.Due to the limited quality and quantity of the included studies,more high quality studies are needed to verify the above conclusion.

Patients with end-stage liver disease after liver transplantation constantly suffer from malnutrition due to primary diseases and transplantation-related factors. Malnutrition will worsen clinical condition of the patients, increase the incidence of complication, length of hospital stay and medical expense after transplantation, and lower the survival rate. Sufficient nutritional support at all stages of liver transplantation is of significance. Accurate assessment of nutritional status and timely intervention are prerequisites for perioperative nutritional treatment in liver transplantation. In this article, the latest nutritional risk screening indexes and evaluation tools, nutritional support methods and other perioperative nutritional intervention measures for liver transplantation were reviewed, aiming to deepen the understanding and cognition of perioperative nutritional therapy for liver transplantation and provide reference for improving nutritional status and clinical prognosis of liver transplant recipients.

0 05) Conclusion N CTCP had a better visualization of the whole biliary tree than PTC or ERCP in patients with obstructive biliary diseases, and had similar results in identifying obstructive location and nature with that of the direct cholangiopancreatography As one of the noninvasive techniques, N CTCP provided another way to diagnose extrahepatic bile obstructive diseases and was an effective alternative to unsuccessful direct cholangiopancreatography or for those patients who were unsuitable for the direct cholangiopancreatography
