After evaluating bile ducts using fluoroscopy, cholangioscopy using a modern digital single-operator cholangioscopy s y s t e m(S py G la s s D S ?) wa s pe r fo r me d dur ing the same procedure with patients under conscious sedation. All patients received peri-interventional antibiotic prophylaxis and bile was collected during the intervention for microbial analysis and for antibiotic susceptibility testing.RESULTS Thirty-three biliary complications were found in a total of 22 patients, whereas four patients showed normal bile ducts. Anastomotic strictures were evident in 14(53.8%) patients, non-anastomotic strictures in seven(26.9%), biliary cast in three(11.5%), and stones in six(23.1%). A benefit of cholangioscopy was seen in 12(46.2%) patients. In four of them, cholangioscopy was crucial for selective guidewire placement prior to planned intervention. In six patients, biliary cast and/or stones failed to be diagnosed by ERCP and were only detectable through cholangioscopy. In one case, a bile duct ulcer due to fungal infection was diagnosed by cholangioscopy. In another case, signs of bile duct inflammation caused by acute cholangitis were evident. One patient developed post-interventional cholangitis. No further procedure-related complications occurred. Thirty-seven isolates were found in bile. Sixteen of these were gram-positive(43.2%), 12(32.4%) were gram-negative bacteria, and Candida species accounted for 24.3% of all isolated microorganisms. Interestingly, only 48.6% of specimens were sensitive to prophylactic antibiotics.CONCLUSION Single-operator cholangioscopy can provide important diagnostic information, helping endoscopists to plan and perform interventional procedures in LT-related biliary complications.展开更多

Although refinements in surgical technique and medical therapy have had a positive influence on the reduction of postoperative morbidity, BC affect 5% to 25% of transplanted patients. Bile leak and anastomotic strictures represent the most common complications. Nowadays, a multidisciplinary approach is required to manage such complications in order to prevent liver failure and retransplantation.展开更多

Retransplantation of the liver(Re LT) remains controversial because of inferior outcomes compared with the primary orthotopic LT(OLT).Meanwhile, if accompanied by vascular complications such as arterial and portal vein(PV) stenosis or thrombosis, it will increase difficulties of surgery. We hereby introduce our center’s experience in Re LT through a complicated case of ReLT.CASE SUMMARY We report a patient who suffered from hepatitis B-associated cirrhosis and underwent LT in December 2012. Early postoperative recovery was uneventful.Four months after LT, the patient’s bilirubin increased significantly and he was diagnosed with an ischemic-type biliary lesion caused by hepatic artery occlusion. The patient underwent percutaneous transhepatic cholangial drainage and repeatedly replaced intrahepatic biliary drainage tube regularly for 5 years.The patient developed progressive deterioration of liver function and underwent liver re-transplant in January 2019. The operation was performed in a classic OLT manner without venous bypass. Both the hepatic artery and PV were occluded and could not be used for anastomosis. The donor PV was anastomosed with the recipient’s left renal vein. The donor hepatic artery was connected to the recipient’s abdominal aorta. The bile duct reconstruction was performed in an end-to-end manner. The postoperative process was very uneventful and the patient was discharged 1 mo after retransplantation.CONCLUSION With the development of surgical techniques, portal thrombosis and arterial occlusion are no longer contraindications for ReLT.展开更多

文摘BACKGROUND The shortage of liver grafts and subsequent waitlist mortality led us to expand the donor pool using liver grafts from older donors.AIM To determine the incidence,outcomes,and risk factors for biliary complications(BC)in liver transplantation(LT)using liver grafts from donors aged>70 years.METHODS Between January 1994 and December 31,2019,297 LTs were performed using donors older than 70 years.After excluding 47 LT for several reasons,we divided 250 LTs into two groups,namely post-LT BC(n=21)and without BC(n=229).This retrospective case-control study compared both groups.RESULTS Choledocho-choledochostomy without T-tube was the most frequent technique(76.2%in the BC group vs 92.6%in the non-BC group).Twenty-one patients(8.4%)developed BC(13 anastomotic strictures,7 biliary leakages,and 1 nonanastomotic biliary stricture).Nine patients underwent percutaneous balloon dilation and nine required a Rouxen-Y hepaticojejunostomy because of dilation failure.The incidence of post-LT complications(graft dysfunction,rejection,renal failure,and non-BC reoperations)was similar in both groups.There were no significant differences in the patient and graft survival between the groups.Moreover,only three deaths were attributed to BC.While female donors were protective factors for BC,donor cardiac arrest was a risk factor.CONCLUSION The incidence of BC was relatively low on using liver grafts>70 years.It could be managed in most cases by percutaneous dilation or Roux-en-Y hepaticojejunostomy,without significant differences in the patient or graft survival between the groups.
文摘Liver transplantation is the current standard of care for end-stage liver disease and an accepted therapeutic option for acute liver failure and primary liver tumors.Despite the remarkable advances in the surgical techniques and immunosuppressive therapy,the postoperative morbidity and mortality still remain high and the leading causes are biliary complications,which affect up to one quarter of recipients.The most common biliary complications are anastomotic and non-anastomotic biliary strictures,leaks,bile duct stones,sludge and casts.Despite the absence of a recommended treatment algorithm many options are available,such as surgery,percutaneous techniques and interventional endoscopy.In the last few years,endoscopic techniques have widely replaced the more aggressive percutaneous and surgical approaches.Endoscopic retrograde cholangiography is the preferred technique when duct-to-duct anastomosis has been performed.Recently,new devices and techniques have been developed and this has led to a remarkable increase in the success rate of minimally invasive procedures.Understanding the mechanisms of biliary complications helps in their early recognition which is the prerequisite for successful treatment.Aggressive endoscopic therapy is essential for the reduction of morbidity and mortality in these cases.This article focuses on the common post-transplant biliary complications and the available interventional treatment modalities.

文摘AIM To evaluate cholangioscopy in addition to endoscopic retrograde cholangiopancreatography(ERCP) for management of biliary complications after liver transplantation(LT).METHODS Twenty-six LT recipients with duct-to-duct biliary reconstruction who underwent ERCP for suspected biliary complications between April and December2016 at the university hospital of Muenster were consecutively enrolled in this observational study. After evaluating bile ducts using fluoroscopy, cholangioscopy using a modern digital single-operator cholangioscopy s y s t e m(S py G la s s D S ?) wa s pe r fo r me d dur ing the same procedure with patients under conscious sedation. All patients received peri-interventional antibiotic prophylaxis and bile was collected during the intervention for microbial analysis and for antibiotic susceptibility testing.RESULTS Thirty-three biliary complications were found in a total of 22 patients, whereas four patients showed normal bile ducts. Anastomotic strictures were evident in 14(53.8%) patients, non-anastomotic strictures in seven(26.9%), biliary cast in three(11.5%), and stones in six(23.1%). A benefit of cholangioscopy was seen in 12(46.2%) patients. In four of them, cholangioscopy was crucial for selective guidewire placement prior to planned intervention. In six patients, biliary cast and/or stones failed to be diagnosed by ERCP and were only detectable through cholangioscopy. In one case, a bile duct ulcer due to fungal infection was diagnosed by cholangioscopy. In another case, signs of bile duct inflammation caused by acute cholangitis were evident. One patient developed post-interventional cholangitis. No further procedure-related complications occurred. Thirty-seven isolates were found in bile. Sixteen of these were gram-positive(43.2%), 12(32.4%) were gram-negative bacteria, and Candida species accounted for 24.3% of all isolated microorganisms. Interestingly, only 48.6% of specimens were sensitive to prophylactic antibiotics.CONCLUSION Single-operator cholangioscopy can provide important diagnostic information, helping endoscopists to plan and perform interventional procedures in LT-related biliary complications.
文摘BACKGROUND Biliary complications(BCs)after liver transplantation(LT)remain a considerable cause of morbidity,mortality,increased cost,and graft loss.AIM To investigate the impact of BCs on chronic graft rejection,graft failure and mortality.METHODS From 2011 to 2016,215 adult recipients underwent right-lobe living-donor liver transplantation(RT-LDLT)at our centre.We excluded 46 recipients who met the exclusion criteria,and 169 recipients were included in the final analysis.Donors’and recipients’demographic data,clinical data,operative details and postoperative course information were collected.We also reviewed the management and outcomes of BCs.Recipients were followed for at least 12 mo post-LT until December 2017 or graft or patient loss.RESULTS The overall incidence rate of BCs including biliary leakage,biliary infection and biliary stricture was 57.4%.Twenty-seven(16%)patients experienced chronic graft rejection.Graft failure developed in 20(11.8%)patients.A total of 28(16.6%)deaths occurred during follow-up.BCs were a risk factor for the occurrence of chronic graft rejection and failure;however,mortality was determined by recurrent hepatitis C virus infection.CONCLUSION Biliary complications after RT-LDLT represent an independent risk factor for chronic graft rejection and graft failure;nonetheless,effective management of these complications can improve patient and graft survival.
文摘BACKGROUND Despite significant advancements in liver transplantation(LT)surgical procedures and perioperative care,post-LT biliary complications(BCs)remain a significant source of morbidity,mortality,and graft failure.In addition,data are conflicting regarding the health-related quality of life(HRQoL)of LT recipients.Thus,the success of LT should be considered in terms of both the survival and recovery of HRQoL.AIM To assess the impact of BCs on the HRQoL of live-donor LT recipients(LDLT-Rs).METHODS We retrospectively analysed data for 25 LDLT-Rs who developed BCs post-LT between January 2011 and December 2016 at our institution.The Short Form 12 version 2(SF 12v2)health survey was used to assess their HRQoL.We also included 25 LDLT-Rs without any post-LT complications as a control group.RESULTS The scores for HRQoL of LDLT-Rs who developed BCs were significantly higher than the norm-based scores in the domains of physical functioning(P=0.003),role-physical(P<0.001),bodily pain(P=0.003),general health(P=0.004),social functioning(P=0.005),role-emotional(P<0.001),and mental health(P<0.001).No significant difference between the two groups regarding vitality was detected(P=1.000).The LDLT-Rs with BCs had significantly lower scores than LDLT-Rs without BCs in all HRQoL domains(P<0.001)and the mental(P<0.001)and physical(P=0.0002)component summary scores.CONCLUSION The development of BCs in LDLT-Rs causes a lower range of improvement in HRQoL.
文摘Postoperative biliary complications remain a substantial challenge after living donor liver transplantation,especially due to its heterogeneous clinical presentation.
文摘Biliary complications(BC) currently represent a major source of morbidity after liver transplantation. Although refinements in surgical technique and medical therapy have had a positive influence on the reduction of postoperative morbidity, BC affect 5% to 25% of transplanted patients. Bile leak and anastomotic strictures represent the most common complications. Nowadays, a multidisciplinary approach is required to manage such complications in order to prevent liver failure and retransplantation.
文摘Orthotopic liver transplantation is the definitive treatment for end-stage liver disease and hepatocellular carcinomas.Biliary complications are the most common complications seen after transplantation,with an incidence of 10-25%.These complications are seen both in deceased donor liver transplant and living donor liver transplant.Endoscopic treatment of biliary complications with endoscopic retrograde cholangiopancreatography(commonly known as ERCP)has become a mainstay in the management post-transplantation.The success rate has reached 80%in an experienced endoscopist's hands.If unsuccessful with ERCP,percutaneous transhepatic cholangiography can be an alternative therapy.Early recognition and treatment has been shown to improve morbidity and mortality in post-liver transplant patients.The focus of this review will be a learned discussion on the types,diagnosis,and treatment of biliary complications post-orthotopic liver transplantation.

文摘BACKGROUND Whether to use a T-tube for biliary anastomosis during orthotopic liver transplantation(OLT)remains a debatable question.Some surgeons chose to use a T-tube because they believed that it reduces the incidence of biliary strictures.Advances in surgical techniques during the last decades have significantly decreased the overall incidence of postoperative biliary complications.Whether using a T-tube during OLT is still associated with the reduced incidence of biliary strictures needs to be re-evaluated.AIM To provide an updated systematic review and meta-analysis on using a T-tube during adult OLT.METHODS In the electronic databases MEDLINE,PubMed,Scopus,ClinicalTrials.gov,the Cochrane Library,the Cochrane Hepato-Biliary Group Controlled Trails Register,and the Cochrane Central Register of Controlled Trials,we identified 17 studies(eight randomized controlled trials and nine comparative studies)from January 1995 to October 2020.The data of the studies before and after 2010 were separately extracted.We chose the overall biliary complications,bile leaks or fistulas,biliary strictures(anastomotic or non-anastomotic),and cholangitis as outcomes.Odds ratios(ORs)with 95%confidence intervals(CIs)were calculated to describe the results of the outcomes.Furthermore,the test for overall effect(Z)was used to test the difference between OR and 1,where P≤0.05 indicated a significant difference between OR value and 1.RESULTS A total of 1053 subjects before 2010 and 1346 subjects after 2010 were included in this meta-analysis.The pooled results showed that using a T-tube reduced the incidence of postoperative biliary strictures in studies before 2010(P=0.012,OR=0.62,95%CI:0.42-0.90),while the same benefit was not seen in studies after 2010(P=0.60,OR=0.76,95%CI:0.27-2.12).No significant difference in the incidence of overall biliary complications(P=0.37,OR=1.41,95%CI:0.66-2.98),bile leaks(P=0.89,OR=1.04,95%CI:0.63-1.70),and cholangitis(P=0.27,OR=2.00,95%CI:0.59-6.84)was observed between using and not using a T-tube before 2010.However,using a T-tube appeared to increase the incidence of overall biliary complications(P=0.049,OR=1.49,95%CI:1.00-2.22),bile leaks(P=0.048,OR=1.91,95%CI:1.01-3.64),and cholangitis(P=0.02,OR=7.21,95%CI:1.37-38.00)after 2010.A random-effects model was used in biliary strictures(after 2010),overall biliary complications(before 2010),and cholangitis(before 2010)due to their heterogeneity(I2=62.3%,85.4%,and 53.6%,respectively).In the sensitivity analysis(only RCTs included),bile leak(P=0.66)lost the significance after 2010 and a random-effects model was used in overall biliary complications(before 2010),cholangitis(before 2010),bile leaks(after 2010),and biliary strictures(after 2010)because of their heterogeneity(I2=92.2%,65.6%,50.9%,and 80.3%,respectively).CONCLUSION In conclusion,the evidence gathered in our updated meta-analysis showed that the studies published in the last decade did not provide enough evidence to support the routine use of T-tube in adults during OLT.
文摘BACKGROUND Biliary strictures after liver transplantation(LT)remain clinically arduous and challenging situations,and endoscopic retrograde cholangiopancreatography(ERCP)has been considered as the gold standard for the management of biliary strictures after LT.Nevertheless,in the treatment of biliary strictures after LT with ERCP,many studies show that there is a large variation in diagnostic accuracy and therapeutic success rate.Digital single-operator peroral cholangioscopy(DSOC)is considered a valuable diagnostic modality for indeterminate biliary strictures.AIM To evaluate DSOC in addition to ERCP for management of biliary strictures after LT.METHODS Nineteen patients with duct-to-duct biliary reconstruction who underwent ERCP for suspected biliary complications between March 2019 and March 2020 at Beijing Chaoyang Hospital,Capital Medical University,were consecutively enrolled in this observational study.After evaluating bile ducts using fluoroscopy,cholangioscopy using a modern digital single-operator cholangioscopy system(SpyGlass DS^(TM))was performed during the same procedure with patients under conscious sedation.All patients received peri-interventional antibiotic prophylaxis.Biliary strictures after LT were classified according to the manifestations of choledochoscopic strictures and the manifestations of transplanted hepatobiliary ducts.RESULTS Twenty-one biliary strictures were found in a total of 19 patients,among which anastomotic strictures were evident in 18(94.7%)patients,while non-anastomotic strictures in 2(10.5%),and space-occupying lesions in 1(5.3%).Stones were found in 11(57.9%)and loose sutures in 8(42.1%).A benefit of cholangioscopy was seen in 15(78.9%)patients.Cholangioscopy was crucial for selective guidewire placement prior to planned intervention in 4 patients.It was instrumental in identifying biliary stone and/or loose sutures in 9 patients in whom ERCP failed.It also provided a direct vision for laser lithotripsy.A spaceoccupying lesion in the bile duct was diagnosed by cholangioscopy in one patient.Patients with biliary stricture after LT displayed four types:(A)mild inflammatory change(n=9);(B)acute inflammatory change edema,ulceration,and sloughing(n=3);(C)chronic inflammatory change;and(D)acute suppurative change.Complications were seen in three patients with post-interventional cholangitis and another three with hyperamylasemia.CONCLUSION DSOC can provide important diagnostic information,helping plan and perform interventional procedures in LT-related biliary strictures.
文摘Biliary complications have always been a dreaded cause of morbidity after living donor liver transplantation.While intrinsic variations in both graft and recipient biliary anatomy remain a significant factor to the difficulty of biliary reconstruction,our institution has taken advantage of its high volume of cases to critically review and evaluate modifiable operative risk factors,in particular,our surgical protocols.We present herein,the evolution of our reconstructive biliary technique from conventional methods to our current standard of microsurgical biliary reconstruction for both graft and recipient ducts.Over this period of transition,our center has created a classification system for biliary reconstruction that decreased the biliary complication rates from 40.0%to 10.2%.

文摘BACKGROUND Cytomegalovirus(CMV)infection is common in liver transplant(LT)_recipients,and biliary complications occur in a large number of patients.It has been reported that CMV-DNA is more detectable in bile than in blood.AIM To investigate the effects of CMV infection on biliary complications by comparing the levels of CMV-DNA in the bile and blood of patients after LT.METHODS We conducted a retrospective analysis of 57 patients who underwent LT,10 of these patients had no biliary complications and 47 patients had biliary complications.We also compared the levels of CMV-DNA in patients’bile and blood,which were sampled concurrently.We used RNAscope technology to identify CMV in paraffin-embedded liver sections.RESULTS CMV-DNA was not detected in bile samples and was detected in 2 blood samples from patients without biliary complications.In the 47 patients with biliary complications,CMV-DNA was detected in 22 bile samples and 8 blood samples,both bile and blood samples were positive for CMV-DNA in 6 patients.The identification rate of CMV-DNA in blood was 17.0%,and was 46.8%in bile.Moreover,tissue samples from 4 patients with biliary complications tested positive using RNAscope technology but were negative with hematoxylin and eosin staining.During the follow-up period,graft failure occurred in 13 patients with biliary complications,8 of whom underwent retransplantation,and 3 died.CMV-DNA in bile was detected in 9 of 13 patients with graft failure.CONCLUSION In patients with biliary complications,the identification rate of CMV-DNA in bile was higher than that in blood.Blood CMV-DNA negative patients with biliary complications should still be monitored for CMV-related biliary tract diseases.Potential occult CMV infection may also be a contributing etiological factor in the development of graft failure.
文摘BACKGROUND Loss of graft function after liver transplantation(LT) inevitably requires liver retransplant. Retransplantation of the liver(Re LT) remains controversial because of inferior outcomes compared with the primary orthotopic LT(OLT).Meanwhile, if accompanied by vascular complications such as arterial and portal vein(PV) stenosis or thrombosis, it will increase difficulties of surgery. We hereby introduce our center’s experience in Re LT through a complicated case of ReLT.CASE SUMMARY We report a patient who suffered from hepatitis B-associated cirrhosis and underwent LT in December 2012. Early postoperative recovery was uneventful.Four months after LT, the patient’s bilirubin increased significantly and he was diagnosed with an ischemic-type biliary lesion caused by hepatic artery occlusion. The patient underwent percutaneous transhepatic cholangial drainage and repeatedly replaced intrahepatic biliary drainage tube regularly for 5 years.The patient developed progressive deterioration of liver function and underwent liver re-transplant in January 2019. The operation was performed in a classic OLT manner without venous bypass. Both the hepatic artery and PV were occluded and could not be used for anastomosis. The donor PV was anastomosed with the recipient’s left renal vein. The donor hepatic artery was connected to the recipient’s abdominal aorta. The bile duct reconstruction was performed in an end-to-end manner. The postoperative process was very uneventful and the patient was discharged 1 mo after retransplantation.CONCLUSION With the development of surgical techniques, portal thrombosis and arterial occlusion are no longer contraindications for ReLT.

文摘Background:The hepatic artery is the only blood source nourishing the biliary duct and associated with biliary complication after liver transplantation(LT).Gastroduodenal artery(GDA)disconnection increased proper hepatic artery flow.Whether this procedure attenuates biliary non-anastomotic stricture(NAS)is not clear.Methods:A total of 241 patients with LT were retrospectively analyzed.The patients were divided into the GDA disconnection(GDA-)and GDA preservation(GDA+)groups.Propensity score matching(PSM)was administrated to reduce bias.Logistic regression was conducted to analyze risk factors for biliary NAS before and after PSM.Postoperative complications were compared.Kaplan-Meier survival analysis and log-rank tests were performed to compare overall survival.Results:In all,99 patients(41.1%)underwent GDA disconnection,and 49(20.3%)developed NAS.Multivariate logistic regression revealed that GDA preservation(OR=2.24,95%CI:1.11-4.53;P=0.025)and model for end-stage liver disease(MELD)score>15(OR=2.14,95%CI:1.12-4.11;P=0.022)were risk factors for biliary NAS.PSM provided 66 pairs using 1:2 matching method,including 66 GDA disconnection and 99 GDA preservation patients.Multivariate logistic regression after PSM also showed that GDA preservation(OR=3.15,95%CI:1.26-7.89;P=0.014)and MELD score>15(OR=2.41,95%CI:1.08-5.36;P=0.031)were risk factors for NAS.When comparing complications between the two groups,GDA preservation was associated with a higher incidence of biliary NAS before and after PSM(P=0.031 and 0.017,respectively).In contrast,other complications including early allograft dysfunction(P=0.620),small-for-size graft syndrome(P=0.441),abdominal hemorrhage(P=1.000),major complications(Clavien-Dindo grade≥3,P=0.318),and overall survival(P=0.088)were not significantly different between the two groups.Conclusions:GDA disconnection during LT ameliorates biliary NAS incidence and may be recommended for application in clinical practice.

文摘Objective:To compare the differences in postoperative survival and complications between extended right liver transplantation(ERLT)and whole liver transplantation(WLT).Methods:The Chinese and English databases were searched for clinical studies on comparing ERLT with WLT for end-stage liver disease from the date of database construction to April 15,2022.The searched literature was de-duplicated and selected according to the order of title,abstract and content,after which NOS quality evaluation was performed for literature that matched the study.Postoperative complications and survival data were extracted from the eligible literature and subjected to Meta-analysis with Review Manager 5.3,and finally data sensitivity analysis and publication bias tests were performed.Results:The complication of ERLT such as biliary complications[OR=1.77,95%CI=(1.39,2.25),P<0.00001],biliary leakage[OR=2.16,95%CI=(1.64,2.84),P<0.0001],total vascular complications[OR=2.00,95%CI=(1.48,2.70),P<0.0001],hepatic arterial thrombosis[OR=2.06,95%CI=(1.50,2.83),P<0.00001],re-Transplantation[OR=1.93,95%CI=(1.53,2.45),P<0.00001]have a higher occurrence rate compared with WLT.While the biliary stenosis[OR=0.74,95%CI=(0.48,1.15),P=0.18],hepatic portal vein thrombosis[OR=1.72,95%CI=(0.84,3.49),P=0.14],primary non-function[OR=1.27,95%CI=(0.80,2.02),P=0.32]had no statistically difference in the incidence of complications after liver transplantation.In terms of survival,ERLT had lower 1-year graft survival rate[OR=0.64,95%CI=(0.54,0.76),P<0.00001]and patient survival rate[OR=0.75,95%CI=(0.62,0.91),P=0.003]than WLT.Fortunately,there was no statistically difference in 5-year graft survival rate[OR=0.97,95%CI=(0.76,1.23),P=0.78]and 5-year patient survival rate[OR=0.94,95%CI=(0.78,1.14),P=0.54].Conclusion:ERLT is a safe and effective treatment for adult end-stage liver disease.As a surgical method with postoperative complications and survival similar to that of WLT,ERLT can increase the source of donor liver.
文摘BACKGROUND Depression,anxiety,and altered self-care ability are among the most important factors affecting the quality of life of liver transplant recipients.Depending on the severity of the underlying liver disease,signs and symptoms of anxiety and depression may become more pronounced.AIM To evaluate the factors affecting depression,anxiety and self-care abilities of liver transplant recipients.METHODS Recipients who are≥18 years and who underwent liver transplantation at Inonu University Liver Transplantation Institute were included in this descriptive and cross-sectional study.Sample size analysis showed that the minimum number of recipients should be 301(confidence level=95%,confidence interval=2.5,population=1382).Three hundred and twenty recipients were interviewed and 316 recipients that have answered the questionnaires accurately were analyzed.The dependent variables were the Beck Depression Scale,State-Trait Anxiety Scale(Form I and II),and Self-Care Agency Scale.The independent variables of the study were sociodemographic characteristics,biliary complications,hepatocellular carcinoma,recommending liver transplantation to other patients,and the interval of out-patient clinic visits.RESULTS Self-care ability scores were lower(P=0.002)and anxiety scores were higher(P=0.004)in recipients with biliary complications.On the other hand,in recipients with hepatocellular carcinoma,self-care scores were lower(P=0.006)while depression(P=0.003)and anxiety scores(P=0.009)were higher.Liver transplantation recipients with a monthly income<3000 Turkish liras had higher depression(P<0.001)and anxiety(P=0.003)scores.The recipients who stated that they would not recommend liver transplantation to others had lower self-care scores(P=0.002),higher depression(P<0.001),higher state anxiety(P=0.02),and trait anxiety(P<0.001)scores.CONCLUSION Presence of biliary complications and hepatocellular carcinoma,low income level,and an obligation for monthly visits to the outpatient clinic are factors that are found to affect self-care capability,depression,and anxiety.

文摘BACKGROUND Cytomegalovirus(CMV)infection is a common infection in liver transplant recipients,which is related to chronic rejection and biliary complications.It is often diagnosed based on serum CMV-DNA or CMV pp65.To our knowledge,this is the first report of the successful treatment of occult CMV cholangitis in a pediatric liver transplantation(LT)recipient.CASE SUMMARY A 7-mo-old baby girl received LT due to biliary atresia and cholestasis cirrhosis.At 1 mo following LT,the patient suffered from aggravated jaundice with no apparent cause.As imaging results showed intrahepatic and extrahepatic bile duct dilatation,the patient was diagnosed with biliary complications and percutaneous cholangiography and biliary drainage was performed.However,there was little biliary drainage and her liver function deteriorated.CMV-DNA was isolated from the bile with the surprising outcome that 3×106 copies/mL were present,whereas the CMV-DNA in serum was negative.Following antiviral therapy with ganciclovir,she gradually recovered and bilirubin decreased to normal levels.During the 4-year follow-up period,her liver function remained normal.CONCLUSION Bile CMV sampling can be used for the diagnosis of occult CMV infection,especially in patients with negative serum CMV-DNA and CMV pp65.Testing for CMV in the biliary tract may serve as a novel approach for the diagnosis of cholestasis post-LT.Timely diagnosis and treatment will decrease the risk of graft loss.
文摘A rare case of occult cytomegalovirus(CMV)cholangitis along with an updated literature review is presented.The patient had not undergone solid organ-bone marrow transplantation and had no chronic autoimmune biliary tract disorder or obvious immunodeficiency.The patient had underwent a pyloric-sparing duodenocephalopancreasectomy,and the postoperative histopathologic examination revealed multiple ulcerative lesions and an occult CMV infection.The copy number of CMV DNA was high(38,000 copies/μg DNA)in common bile duct surgical specimens measured by real-time quantitative polymerase chain reaction.CMV was not detected in blood and urine samples from the patient after full doses of intravenous ganciclovir and full doses of oral valganciclovir antiviral therapy.This report recapitulates the role of CMV in causing severe cholangiopathy in the absence of obvious immunosuppression or autoimmune disorder of the biliary tract.

文摘Background:Although laparoscopic living donor left lateral section liver procurements represents an established and safe procedure,there remains much discussion on this topic.In particular,the issue of whether laparoscopic living donor liver procurement increases the difficulty of the surgery and potential complications for recipients continue to confound experts in this field.Methods:In this report,data from 180 cases of living donor left lateral section liver transplantation patients were analyzed retrospectively.Of these 180 cases,106 grafts were procured by open surgery and 74 by pure laparoscopic surgery.Results:While surgery durations and blood loss were decreased in donors from the laparoscopic surgery group,increased biliary openings of grafts and relatively high peak aspartate aminotransferase(AST)levels were present in both donors and recipients with this procedure.Conclusions:Laparoscopic living donor left lateral section liver procurement represents a safe and effective procedure for both donors and recipients.However,laparoscopic surgery can more frequently lead to multiple biliary tracts in the graft and its impact on the prognosis of recipients remains uncertain.Use of routine X-ray based intraoperative cholangiography may help to reduce this problem.
