Psychological Outcomes of Living Liver Donors From a Multicenter Prospective Study: Results From the Adult-to-Adult Living Donor Liver Transplantation Cohort Study2 (A2ALL-2)

The incidence of adverse outcome in donors after living donor liver transplantation: A meta-analysis of 60,829 donors

The scarcity of liver grafts has prompted developments in living donor liver transplantations (LDLT), with previous literature illustrating similar outcomes in recipients compared to deceased donor transplants. However, significant concerns regarding living donor morbidity and mortality have yet to be examined comprehensively. This study aims to provide estimates of the incidence of various outcomes in living liver donors. In this meta-analysis, Medline and Embase were searched from inception to July 2022 for articles assessing the incidence of outcomes in LDLT donors. Complications in the included studies were classified into respective organ systems. Analysis of incidence was conducted using a generalized linear mixed model with Clopper-Pearson intervals. Eighty-seven articles involving 60,829 living liver donors were included. The overall pooled incidence of complications in LDLT donors was 24.7% (CI: 21.6%-28.1%). The incidence of minor complications was 17.3% (CI: 14.7%-20.3%), while the incidence of major complications was lower at 5.5% (CI: 4.5%-6.7%). The overall incidence of donor mortality was 0.06% (CI: 0.0%-0.1%) in 49,027 individuals. Psychological complications (7.6%, CI: 4.9%-11.5%) were the most common among LDLT donors, followed by wound-related (5.2%, CI: 4.4%-6.2%) and respiratory complications (4.9%, CI: 3.8%-6.3%). Conversely, cardiovascular complications had the lowest incidence among the subgroups at 0.8% (CI: 0.4%-1.3%). This study presents the incidence of post-LDLT outcomes in living liver donors, illustrating significant psychological, wound-related, and respiratory complications. While significant advancements in recent decades have contributed towards decreased morbidity in living donors, our findings call for targeted measures and continued efforts to ensure the safety and quality of life of liver donors post-LDLT.

Development of a model to predict the risk of early graft failure after adult-to-adult living donor liver transplantation: An ELTR study

Graft survival is a critical end point in adult-to-adult living donor liver transplantation (ALDLT), where graft procurement endangers the lives of healthy individuals. Therefore, ALDLT must be responsibly performed in the perspective of a positive harm-to-benefit ratio. This study aimed to develop a risk prediction model for early (3 months) graft failure (EGF) following ALDLT. Donor and recipient factors associated with EGF in ALDLT were studied using data from the European Liver Transplant Registry. An artificial neural network classification algorithm was trained on a set of 2073 ALDLTs, validated using cross-validation, tested on an independent random-split sample (n=518), and externally validated on United Network for Organ Sharing Standard Transplant Analysis and Research data. Model performance was assessed using the AUC, calibration plots, and decision curve analysis. Graft type, graft weight, level of hospitalization, and the severity of liver disease were associated with EGF. The model ( http://ldlt.shinyapps.io/eltr_app ) presented AUC values at cross-validation, in the independent test set, and at external validation of 0.69, 0.70, and 0.68, respectively. Model calibration was fair. The decision curve analysis indicated a positive net benefit of the model, with an estimated net reduction of 5-15 EGF per 100 ALDLTs. Estimated risks>40% and<5% had a specificity of 0.96 and sensitivity of 0.99 in predicting and excluding EGF, respectively. The model also stratified long-term graft survival ( p <0.001), which ranged from 87% in the low-risk group to 60% in the high-risk group. In conclusion, based on a panel of donor and recipient variables, an artificial neural network can contribute to decision-making in ALDLT by predicting EGF risk.

Systematic review and meta-analysis of open versus laparoscopy-assisted versus pure laparoscopic versus robotic living donor hepatectomy

The value of minimally invasive approaches for living donor hepatectomy remains unclear. Our aim was to compare the donor outcomes after open versus laparoscopy-assisted versus pure laparoscopic versus robotic living donor hepatectomy (OLDH vs. LALDH vs. PLLDH vs. RLDH). A systematic literature review of the MEDLINE, Cochrane Library, Embase, and Scopus databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (up to December 8, 2021). Random-effects meta-analyses were performed separately for minor and major living donor hepatectomy. The risk of bias in nonrandomized studies was assessed using the Newcastle-Ottawa Scale. A total of 31 studies were included. There was no difference in donor outcomes after OLDH versus LALDH for major hepatectomy. However, PLLDH was associated with decreased estimated blood loss, length of stay (LOS), and overall complications versus OLDH for minor and major hepatectomy, but also with increased operative time for major hepatectomy. PLLDH was associated with decreased LOS versus LALDH for major hepatectomy. RLDH was associated with decreased LOS but with increased operative time versus OLDH for major hepatectomy. The scarcity of studies comparing RLDH versus LALDH/PLLDH did not allow us to meta-analyze donor outcomes for that comparison. There seems to be a marginal benefit in estimated blood loss and/or LOS in favor of PLLDH and RLDH. The complexity of these procedures limits them to transplant centers with high volume and experience. Future studies should investigate self-reported donor experience and the associated economic costs of these approaches.

Prevalence and factors associated with depression and anxiety in living liver donors: A systematic review and meta-analysis

OBJECTIVE

This study aimed to systematically review the prevalence and factors associated with depression and anxiety in living liver donors after liver transplantation.

METHODS

Five English language electronic databases and four Chinese language electronic databases were searched from inception to February 2023. Two investigators independently extracted the data and assessed the study quality. The pooled prevalence was calculated using STATA software (version 14.0). We performed a narrative review to summarize the factors associated with depression and anxiety in living liver donors after liver transplantation. The protocol of this study was registered with the International Prospective Register of Systematic Reviews (PROSPERO) database, registration number: CRD42021290071.

RESULTS

This study included 39 articles involving 18,577 participants. The pooled prevalence was 6.3% [95% confidence interval (CI) (4.1-8.9%)] for depression in living liver donors, and 10.0% [95% CI (4.0-18.1%)] for anxiety. Prevalence of clinically significant depressive or anxiety symptoms was higher (15.7% and 17.4%) compared with disorders (2.7% and 2.2%). The prevalence of depression and anxiety was highest within 3 months post-donation. Specifically, female donors, serious postoperative complications, and recipients' poor health/death have been reported as factors having a negative influence on depression and anxiety.

CONCLUSIONS

Collected evidence showed that the overall prevalence of depression or anxiety of living liver donors was high. Therefore, early detection and timely treatment of psychological disorders are crucial to promote positive psychiatric health outcomes and ensure the quality of life of living liver donors.

Donor safety of remnant liver volumes of less than 30% in living donor liver transplantation: A systematic review and meta-analysis

PURPOSE

This meta-analysis aimed to investigate the acceptability of donor remnant liver volume (RLV) to total liver volume (TLV) ratio (RLV/TLV) being <30% as safe in living donor liver transplantations (LDLTs).

METHODS

Online databases were searched from January 2000 to June 2022. Pooled odds ratios (ORs) and standardized mean differences (SMDs) with 95% confidence intervals (CIs) were calculated using fixed- or random-effects model.

RESULTS

One prospective and seven retrospective studies comprising 1935 patients (164 RLV/TLV <30% vs. 1771 RLV/TLV ≥30%) were included. Overall (OR = 1.82; 95% CI [1.24, 2.67]; p = .002) and minor (OR = 1.88; 95% CI [1.23, 2.88]; p = .004) morbidities were significantly lower in the RLV/TLV ≥30% group than in the RLV/TLV <30% group (OR = 1.82; 95% CI [1.24, 2.67]; p = .002). No significant differences were noted in the major morbidity, biliary complications, and hepatic dysfunction. Peak levels of bilirubin (SMD = .50; 95% CI [.07, .93]; p = .02) and international normalized ratio (SMD = .68; 95% CI [.04, 1.32]; p = .04) were significantly lower in the RLV/TLV ≥ 30% group than in the RLV/TLV <30% group. No significant differences were noted in the peak alanine transferase and aspartate transaminase levels and hospital stay.

CONCLUSIONS

Considering the safety of the donor as the top priority, the eligibility of a potential liver donor in LDLT whose RLV/TLV is expected to be <30% should not be accepted.

Living donor liver transplant candidate and donor selection and engagement: Meeting report from the living donor liver transplant consensus conference

INTRODUCTION

Living donor liver transplantation (LDLT) is a promising option for mitigating the deceased donor organ shortage and reducing waitlist mortality. Despite excellent outcomes and data supporting expanding candidate indications for LDLT, broader uptake throughout the United States has yet to occur.

METHODS

In response to this, the American Society of Transplantation hosted a virtual consensus conference (October 18-19, 2021), bringing together relevant experts with the aim of identifying barriers to broader implementation and making recommendations regarding strategies to address these barriers. In this report, we summarize the findings relevant to the selection and engagement of both the LDLT candidate and living donor. Utilizing a modified Delphi approach, barrier and strategy statements were developed, refined, and voted on for overall barrier importance and potential impact and feasibility of the strategy to address said barrier.

RESULTS

Barriers identified fell into three general categories: 1) awareness, acceptance, and engagement across patients (potential candidates and donors), providers, and institutions, 2) data gaps and lack of standardization in candidate and donor selection, and 3) data gaps regarding post-living liver donation outcomes and resource needs.

CONCLUSIONS

Strategies to address barriers included efforts toward education and engagement across populations, rigorous and collaborative research, and institutional commitment and resources.

Donor and Donation Images (DDI)-A Scoping Review of What We Know and What We Don't

Organ transplantation is associated with significant physical and psychological burden for the recipients. Qualitative reports indicate that organ recipients develop donor and donation images (DDI)-conceptions of the donor and/or the organ. A deeper understanding of DDI is needed in the care of transplant recipients. To present the current state of knowledge, we searched for and identified DDI-related publications in PubMed and Scopus. Inclusion criteria were (1) studies addressing transplant recipients, and (2) English or German language. Twenty-one studies of individuals with transplanted hearts, lungs, or kidneys were included in this scoping review. Prevalence for DDI ranged from 6% to 52.3%. DDI occurs both before and after transplantation and includes ideas about the donor as well as whether and how the recipient's personality may be altered by the transplanted organ. Some transplant recipients did indeed report personality changes following transplantation due to the adoption of assumed donor characteristics. One study showed a positive association between the presence of DDI and anxiety scores and one described a coping effect. DDI is understudied and should be systematically assessed to improve care for the vulnerable group of individuals undergoing organ transplantation. Current research gaps and future directions are discussed.

Liver Paired Exchange: Programmatic Hopes and Fears

The dearth of deceased liver donors has created a supply demand gap, necessitating creation of living donor liver transplantation. However, living donor liver transplantation has relied on directed donation, whereby many potential directed donors are rejected based on ABO blood group incompatibility, hepatic size incompatibility, or the need for biliary or arterial reconstruction during transplant surgery. Much like kidney paired exchange, liver paired exchange (LPE) circumvents these incompatibility issues by relying on anonymous, nondirected, or bridge donors that are better anatomical or histological matches for recipients. Although Asia has taken the lead in LPE, the process has only recently been adopted in North America, with the first successful surgery done in the United States in 2019. Our review article sheds light on the process of LPE and the success of LPE in the United States thus far and, additionally, highlights the several logistical and ethical challenges that must be considered as transplant centers adopt and scale up LPE across the United States to address the increased demand for liver allografts.

Influence of surgical technique in donor hepatectomy on immediate and short-term living donor outcomes - A systematic review of the literature, meta-analysis, and expert panel recommendations

BACKGROUND

There are currently no guidelines pertaining to ERAS pathways in living donor hepatectomy.

OBJECTIVES

The aim of this study was to identify whether surgical technique influences immediate and short-term outcomes after living liver donation surgery.

DATA SOURCES

Ovid MEDLINE, Embase, Scopus, Google Scholar, and Cochrane Central.

METHODS

Systematic review and meta-analysis following PRISMA guidelines and recommendations using the GRADE approach derived from an international expert panel (CRD42021260707). Endpoints were mortality, overall complications, serious complications, bile eaks, pulmonary complications, estimated blood loss and length of stay.

RESULTS

Of the 2410 screened articles, 21 articles were included for final analysis; three observational, 13 retrospective cohort, four prospective cohort studies, and one randomized trial. Overall complications were higher with right versus left hepatectomy (26.8% vs. 20.8%; OR 1.4, P = .010). Donors after left hepatectomy had shorter length of stay (MD 1.4 days) compared to right hepatectomy. There was no difference in outcomes after right donor hepatectomy with versus without middle hepatic vein. We had limited data on the influence of incision type and minimally invasive approaches on living donor outcomes, and no data on the effect of operative time on donor outcomes.

CONCLUSIONS

Left donor hepatectomy should be preferred over right hepatectomy, as it is related to improved donor short-term outcomes (QOE; Moderate | Grade of Recommendation; Strong). Right donor hepatectomy with or without MHV has equivalent outcomes (QOE; Moderate | Grade of Recommendation; Strong); no preference is recommended, decision should be based on program's experience and expertise. No difference in outcomes was observed related to incision type, minimally invasive vs. open (QOE; Low | Grade of Recommendation; Weak); no preference can be recommended.

Long-term follow-up of living liver donors: A single-center experience

Living donors are healthy individuals who are exposed to a major surgical procedure during which a major part of their liver is resected. Data on the long-term consequences of living liver donation are scarce. This study examined clinical, laboratory, and long-term health-related quality of life (HRQoL) in 237 living liver donors and 239 matched controls during 48-168 months of postdonation follow-up. We used the 36-item short-form health survey (SF-36), version 1. The scores for the four following subscales were higher in nondonors than in donors: physical functioning (p = 0.009), role limitations due to physical health (p = 0.002), energy/fatigue (p < 0.001), and bodily pain (p < 0.001). The scores on the eight subscales of the SF-36 were higher in donors with living recipients than in donors whose recipients died (p < 0.001). Our results suggest that living donor right hepatectomy is safe and results in a postdonation HRQoL similar to that of nondonors in those donors whose recipients are healthy, whereas donors whose recipients die have a lower HRQoL that is significantly negatively correlated with the time since recipient death and improves over time.

The use of nondirected donor organs in living donor liver transplantation: Perspectives and guidance

Interest in anonymous nondirected living organ donation is increasing in the United States and a small number of transplantation centers are accumulating an experience regarding nondirected donation in living donor liver transplantation. Herein, we review current transplant policy, discuss emerging data, draw parallels from nondirected kidney donation, and examine relevant considerations in nondirected living liver donation. We aim to provide a consensus guidance to ensure safe evaluation and selection of nondirected living liver donors and a schema for just allocation of nondirected grafts.

Perioperative management of living donor liver transplantation: Part 2 - Donors

Living donor liver transplantation was first developed to mitigate the limited access to deceased donor organs in Asia in the 1990s. This alternative liver transplantation method has become a widely practiced and established transplantation option for adult patients suffering with end-stage liver disease, and it has successfully helped address the shortage of deceased donors. The Society for the Advancement of Transplant Anesthesia and the Korean Society of Transplantation Anesthesiologists jointly reviewed published studies on the perioperative management of adult live liver donors undergoing donor hemi-hepatectomy. The goal of the review is to offer transplant anesthesiologists and critical care physicians a comprehensive overview of the perioperative management of adult live donors. We featured the current status, donor selection process, outcomes and complications, surgical procedure, anesthetic management, Enhanced Recovery After Surgery protocols, avoidance of blood transfusion, and considerations for emergency donation. Recent surgical advances, including laparoscopic donor hemi-hepatectomy and robotic laparoscopic donor surgery, are also addressed.

CANLI KARACİĞER DONÖRLERİNDE YAŞAM KALİTESİNİN DEĞERLENDİRİLMESİ

Objective: In this study, it was aimed to examine the effect of transplantation on physical, mental and psychosocial health of donors by evaluating the quality of life of living liver donors after transplantation. Methods: The study was conducted with three groups at XXXX University Faculty of Medicine Organ Transplantation and Research Center. 43 living donors from 2017 and 43 living donors from 2007-2016 who underwent liver transplantation were randomly selected to participate in the study. Also 43 control subjects were selected randomly from the community. The study was conducted by a single interviewer between 01.02.2018 and 31.05.2018 by telephone or e-mail. The socio-demographic data questionnaire, Short Form-36 (SF-36) and Hospital Anxiety-Depression Scale (HADS) prepared by the researchers were applied to all participants. Results: The mean age of the participants was 38.04 ± 9.84 years, and of these participants 48.1% (n= 62) of them were female. When donors and control group were evaluated in terms of their quality of life, no significant difference was found between physical role, energy(vitality) and mental health subgroups(p> 0.05). However, donors have a better quality of life in physical functioning, emotional aspect, social functioning, pain and general health subgroups. It was detected that the quality of life was not affected by age, gender, marital status, educational status, economic status, job loss, comorbidity or disturbance by presence of operational scar. Only sexual problems and the loss of the recipient’s life were observed to have a negative impact on the quality of life. There was no significant difference between the groups in terms of anxiety and depression (p

Pregnancy Outcomes After Living Liver Donation: A Multi-Institutional Study

Nearly half of living liver donors in North America are women of child-bearing age. Fetal and maternal outcomes after donation are unknown. We conducted a retrospective cohort study of female living liver donors (aged 18-50 years at donation) from 6 transplant centers. Participants were surveyed about their pregnancies and fertility. Outcomes were compared between predonation and postdonation pregnancies. Generalized estimating equations were clustered on donor and adjusted for age at pregnancy, parity, and pregnancy year. Among the 276 donors surveyed, 151 donors responded (54.7% response rate) and reported 313 pregnancies; 168/199 (68.8%) of the predonation pregnancies and 82/114 (71.9%) of the postdonation pregnancies resulted in live births, whereas 16.6% and 24.6% resulted in miscarriage, respectively. Women with postdonation pregnancies were older (32.0 versus 26.7 years; P < 0.001) and more frequently reported abnormal liver enzymes during pregnancy (3.5% versus 0.0%; P = 0.02) and delivery via cesarean delivery (35.4% versus 19.7%; P = 0.01). On adjusted analysis, there was no difference in cesarean delivery (odds ratio [OR], 2.44; 95% confidence interval [95% CI], 0.98-6.08), miscarriage (OR, 1.59; 95% CI, 0.78-3.24), combined endpoints of pregnancy-induced hypertension and preeclampsia (OR, 1.27; 95% CI, 0.36-4.49), or intrauterine growth restriction and preterm birth (OR, 0.91; 95% CI, 0.19-4.3). Of the 49 women who attempted pregnancy after donation, 11 (22.5%) self-reported infertility; however, 8/11 (72.7%) eventually had live births. Aside from increased reporting of abnormal liver enzymes and cesarean deliveries, there was no significant difference in pregnancy outcomes before and after living liver donation. One-fifth of women who attempt pregnancy after liver donation reported infertility, and although the majority went on to successful live births, further exploration is needed to understand the contributing factors. Future research should continue to monitor this patient-centered outcome across a large cohort of donors.

Post-operative outcomes in anonymous living liver donors: What motivates individuals to donate to strangers

Anonymous living donor liver transplantation (LDLT) is a strategy to address the shortage of available transplantable livers; however, few studies have been conducted on this population. The objective of this study was to describe the motivations and medical, psychosocial, and financial outcomes of anonymous living liver donors. Between 2010-2019, 116 anonymous living liver donors were evaluated, 59 (51.7%) of whom proceeded to surgery. A subset of 21 anonymous donors were matched to biologically/emotionally related donors according to age, gender, race, and duration since surgery. A medical chart review and post-surgical interviews were performed to assess medical and financial outcomes. The primary motivation for donors was an unselfish desire to help others (43, 72.9%). A total of 13 (22%) anonymous donors experienced complications. Of these, 7 (11.9%) were grade I Clavien-Dindo classification, 5 (8.5%) grade II, and 1 was grade III (1.7%); and no patients had grade IV-V Clavien-Dindo complications. Increased anxiety was reported by 3 (5.1%) donors, and one donor reported clinical levels of depression (1.7%). Within the matched controls, anonymous donors were not significantly different to biologically/emotionally related donors with regard to surgical complications, psychosocial, or financial outcomes. Allowing a greater number of anonymous donors may facilitate the reduction of the waitlist for liver transplant candidates. This article is protected by copyright. All rights reserved.

Mental Health and Well-Being of Solid Organ Transplant Donors. The Forgotten Sacrifices

In light of a global organ shortage, living donor transplantation has become increasingly relevant as an alternative to deceased donor transplantation. While current research has revolved around the medical aspects of transplantation, there remains a paucity of literature regarding the quality of life (QOL) of living donors. Hence, this review aims to provide a comprehensive outline of the current landscape of living liver and kidney transplantation, with a focus on the mental health and wellbeing of donors. As highlighted in previous studies, organ donation has a significant impact on both physical and mental aspects of donor wellbeing, with marked deteriorations occurring in the short term. Furthermore, other qualitative aspects such as financial burden contribute greatly to donor distress, reflecting a need for improved donor care. To address these pertinent issues, recommendations for a successful transplant program are detailed in this review, which encompasses psychological and social aspects of donor care throughout the donation process. Further research can be done on the impact of recipient deaths on donor QOL and appropriate interventions. Overall, given the selfless sacrifices of living donors, the care of their mental wellbeing is essential. Therefore, greater emphasis should be placed on the provision of adequate psychosocial support for them.

A Meta-Analysis on the Incidence of Donor Related Depression after Liver Transplant

AIM

Living donor liver transplantation (LDLT) is increasing, yet gaps exist in the understanding of psychological wellbeing of donors after liver transplant. This meta-analysis seeks to evaluate the incidence and risk factors for donor-related depression after liver transplantation.

METHODS

A search was conducted on Medline and Embase database. Articles assessing incidence of depression in LDLT donors were included. Incidence was pooled after Freeman-Tukey double-arcsine transformation. For risk factors, dichotomous variables were analyzed with generalized linear model while a conventional meta regression with logit transformation was conducted for continuous variables.

RESULTS

Of 1,069 abstracts, 40 articles underwent full-text review. 17 articles were included. The pooled incidence of depression among 1,888 LT donors was 7.66% (CI: 4.47% - 12.80%). Depression rates were significantly higher in Asian compared to Western studies (RR: 1.73, CI: 1.19 - 2.52, p=0.0039). Female gender (p<0.001), Caucasian ethnicity (p=0.047), employment status (p<0.001) and lower education levels (p=0.044) were significantly associated with depression. Donor relationship with recipients was not a significant risk factor.

CONCLUSIONS

LDLT remains a core aspect of the treatment of end-stage liver disease. However, the high depression rates after LT suggest that there remains room for improvement in the care of donors' mental health post-transplant.

Preoperative and Postoperative Endogenous Melatonin and Anxiety Levels and Their Correlation in Living Liver Donors

OBJECTIVES

High anxiety levels may lead to mental and physical changes that may affect quality of life. Melatonin has anxiolytic properties. It has been reported that administration of melatonin reduces anxiety. In this study, we examined the preoperative and postoperative anxiety levels of living liver donors and the correlation between anxiety levels and endogenous melatonin levels.

MATERIALS AND METHODS

This prospective clinical study included 56 living liver donors who underwent right hepatectomy (39 women, 17 men; average age of 29 ± 7 years). The anxiety levels were evaluated by using the Spielberger State-Trait Anxiety Inventory Test with a form for this test used to measure the current state of anxiety score and another form used to measure the underlying anxiety score of the patient. These forms were applied preoperatively and postoperatively. Blood samples were taken simultaneously for melatonin levels. Melatonin levels were measured using high-pressure liquid chromatography. Our primary outcomes were to determine the preoperative and postoperative endogenous melatonin and anxiety levels of living liver donors and to investigate their correlations.

RESULTS

A statistically significant difference was observed between preoperative and postoperative state of anxiety scores. The preoperative and postoperative underlying anxiety scores were similar. A statistically significant difference was found between the preoperative endogenous melatonin level and postoperative endogenous melatonin level. A significant correlation was not observed between the preoperative and postoperative current and underlying anxiety levels or endogenous melatonin levels.

CONCLUSIONS

Living liver donors had high anxiety levels during the preoperative and postoperative periods. A significant decrease was identified in the postoperative hour 24 endogenous melatonin level. These results may lay the foundation for interventions that can identify emotional changes as well as control and improve the mental health of living liver donors.

Depression, anxiety, and associated psychological outcomes in living organ transplant donors: A systematic review

With increasing demands for living organ donations, understanding the prevalence of depression and anxiety, which are the commonest psychiatric disorders in donors following organ transplantation, will serve to improve psychiatric care to safeguard donors' mental wellbeing. This descriptive systematic review examines all observational studies in English investigating prevalence of depression and anxiety in adult transplant donors using bibliographic databases. Sixty-two papers were included (kidney, n = 25; liver, n = 25; bone marrow, n = 7; uterus, n = 2; lung, n = 1; kidney and lung concurrently, n = 2). Post-transplantation depression and anxiety prevalence rates (Depression: 0-46.9%, Anxiety: 0-66.7%) did not differ significantly from pre-transplantation and were largely comparable to the general population. Other psychiatric disorders observed included bipolar disorder, conversion disorder, adjustment disorder and sleep disorder. Other psychological outcomes observed included lower quality of life, lower satisfaction of life and regret after donation. Pre-donation risk factors such as poor physical/psychological health status, and post-donation risk factors such as complicated post-surgical recovery and poor physical/psychological health in recipients were identified, predisposing donors to poor psychological outcomes. Individuals with risk factors should be monitored and provided with social support, psychoeducation, psychotherapy and long-term follow up. Future studies should adopt consistent methodological approaches to improve comparability between various studies. More research investigating poor psychological outcomes in other organ donors besides kidney and liver donors, donors who have past psychiatric history, unrelated and parent donors is warranted.

Prevention of delayed gastric emptying after living donor left hepatectomy

BACKGROUND

Delayed gastric emptying (DGE) is uncomfortable complication after left hepatectomy. The aim of this study is to show our strategy to prevent DGE after living donor left hepatectomy.

METHODS

The cases were divided into 3 groups as without any prevention (control group), prevented DGE with putting omentum between the liver and pylorus (O group), and with putting a Seprafilm (S group). The incidence of DGE and the CT finding 1 month after surgery were retrospectively compared between the groups.

RESULTS

The incidence of DGE was significantly decreased in O and S group than control group (P < 0.05, Fisher's test). In S group, fluid collection along the cutting surface of the liver was observed on CT significantly more than other groups, but the incidence of bile leakage was adversely less in S groups than other groups, meaning that collected fluid in S group were presumed as the ascites without bile.

CONCLUSION

Omentum patching and Seprafilm were equally effective to prevent DGE after living donor left hepatectomy, and Seprafilm might be better because it is more physiologic.

Living donor liver paired exchange: A North American first

Paired organ exchange can be used to circumvent living donor-recipient ABO incompatibilities. Herein, we present the first case of successful liver paired exchange in North America. This 2-way swap required 4 simultaneous operations: 2 living donor hepatectomies and 2 living donor liver transplants. A nondirected anonymous living donor gift initiated this domino exchange, alleviating an ABO incompatibility in the other donor-recipient pair. With careful attention to ethical and logistical issues, paired liver exchange is a feasible option to expand the donor pool for incompatible living liver donor-recipient pairs.

Changes in the quality of life of living liver donors: A meta-analysis

BACKGROUND

Comprehending the physical, psychological, social benefits, and harm associated with liver donation is critical in promoting practices to maintain donors' long-term health. However, changes in quality of life among living liver donors pre- and post-donation have not been established.

OBJECTIVE

This meta-analysis of prospective longitudinal studies examined the quality of life changes among living liver donors pre- and post-donation.

METHODS

PubMed, Embase, CINHAL with full text, and ProQuest Dissertations & Theses were mainly searched for full-text articles from inception till December 2018 to identify studies assessing the quality of life of living liver donors. The methodological quality of the included studies was examined. The quality of life post-donation at five assessment points, ≤1 month, 3 months, 6 months, 12 months, and ≥ 24 months were compared with the pre-donation, respectively.

RESULTS

The search yielded 2215 records, and a total of 15 articles (13 studies) with 715 donors were included in this meta-analysis. Physical functioning scores at ≤1 month, 3 months, 6 months, 12 months, and ≥24 months post-donation were significantly lower than pre-donation [overall standardized mean difference (SMD) = -0.67, 95% CI: -0.86, -0.49; p ≤]. Significantly higher level of pain was found at 3-month post-donation (SMD, -1.05; 95% CI: -1.26, -0.85; p < 0.00001). Also, a significantly higher level of anxiety was found at 3-month post-donation (SMD, -0.29; 95%CI: -0.51, -0.07; p = 0.01), but there were no significant changes in general psychological state and depression. A significant reduction in donors' social quality of life (SMD, -2.61; 95%CI: -4.75, 0.48; p = 0.02) was found at ≤1-month post-donation, and recovery to pre-donation levels occurred at 3 months post-donation.

CONCLUSIONS

Living liver donation was associated with a decline in physical functioning, which was sustained for longer than 2 years post-donation. Impaired social and psychological quality of life affected donors for 1-3 months after their donation. The quality of life of living liver donors has become a pressing issue requiring more attention from doctors and nurses within the transplant team. However, multicenter, prospective, and longitudinal studies are needed to confirm the long-term safety of living liver donors.

Clinical Features and Long-Term Outcomes of Living Donors of Liver Transplantation Who Developed Psychiatric Disorders

BACKGROUND In the field of living donor liver transplantation (LDLT), it is important to ensure donor's psychological well-being. We report on clinical features and long-term outcomes of LDLT donors who developed psychiatric disorders after their donor operations. Additionally, we compare patient backgrounds, as well as surgical and perioperative aspects between LDLT donors with and without postoperative psychiatric complications. MATERIAL AND METHODS Between November 1998 and March 2018, we identified 254 LDLT donors at our hospital. Among these, we investigated those who had newly developed psychiatric complications and required psychiatric treatment after donor operation. RESULTS The median duration of follow-up was 4 years. Sixty-five donors were lost to follow-up. Eight donors (3.1%) developed postoperative psychiatric complications, including major depressive disorder in 4, panic disorder in 2, conversion disorder and panic disorder in 1, and adjustment disorder in 1. The median duration from donor surgery to psychiatric diagnosis was 104.5 days (range, 12 to 657 days) and the median treatment duration was 18 months (range, 3 to 168 months). Of those, 3 donors required psychiatric treatment over 10 years, and 4 donors remained under treatment. The duration of hospital stay after donor operation was significantly longer and perioperative complications with Clavien classification greater than grade IIIa were more frequent in donors with psychiatric complications than in those without psychiatric complications (P=0.02 and P=0.006, respectively). CONCLUSIONS Accurate diagnosis and appropriate treatment for psychiatric disorders by psychiatrists and psychologists are important during LDLT donor follow-up. Minimization of physiological complications might be important to prevent postoperative psychiatric complications in LDLT donors.

Donor outcomes in anonymous live liver donation

BACKGROUND & AIMS

Death rates on liver transplant waiting lists range from 5%-25%. Herein, we report a unique experience with 50 anonymous individuals who volunteered to address this gap by offering to donate part of their liver to a recipient with whom they had no biological connection or prior relationship, so called anonymous live liver donation (A-LLD).

METHODS

Candidates were screened to confirm excellent physical, mental, social, and financial health. Demographics and surgical outcomes were analyzed. Qualitative interviews after donation examined motivation and experiences. Validated self-reported questionnaires assessed personality traits and psychological impact.

RESULTS

A total of 50 A-LLD liver transplants were performed between 2005 and 2017. Most donors had a university education, a middle-class income, and a history of prior altruism. Half were women. Median age was 38.5 years (range 20-59). Thirty-three (70%) learned about this opportunity through public or social media. Saving a life, helping others, generativity, and reciprocity for past generosity were motivators. Social, financial, healthcare, and legal support in Canada were identified as facilitators. A-LLD identified most with the personality traits of agreeableness and conscientiousness. The median hospital stay was 6 days. One donor experienced a Dindo-Clavien Grade 3 complication that completely resolved. One-year recipient survival was 91% in 22 adults and 97% in 28 children. No A-LLD reported regretting their decision.

CONCLUSIONS

This is the first and only report of the characteristics, motivations and facilitators of A-LLD in a large cohort. With rigorous protocols, outcomes are excellent. A-LLD has significant potential to reduce the gap between transplant organ demand and availability.

LAY SUMMARY

We report a unique experience with 50 living donors who volunteered to donate to a recipient with whom they had no biological connection or prior relationship (anonymous living donors). This report is the first to discuss motivations, strategies and facilitators that may mitigate physical, social and ethical risk factors in this patient population. With rigorous protocols, anonymous liver donation and recipient outcomes are excellent; with appropriate clinical expertise and system facilitators in place, our experience suggests that other centers may consider the procedure for its significant potential to reduce the gap between transplant organ demand and availability.

Psychosocial Issues Related to Donor's Decision-Making in Living Donor Liver Transplantation

Background

The aim of this study was to investigate the detailed motives, concerns, and psychological defensiveness of living liver donor candidates in a Korean population.

Material/Methods

We analyzed data of 102 donor candidates obtained from routine psychosocial evaluation for living donor liver transplantation (LDLT) using descriptive methods. Donor candidates completed 2 questionnaires regarding their motivations and concerns, as well as a validity scale, the K scale from the Minnesota Multiphasic Personality Inventory-2.

Results

Donor candidates were more likely to cite family-related issues (77.5% to 94.1%) including well-being of the whole family and family affection as the reasons for their liver donation rather than personal motives (38.2% to 57.8%). Donors were also more likely to concern about the recipient’s survival and recovery (52.9% to 58.8%) rather than their own difficulties such as surgical complications and occupational disadvantages (19.6% to 38.2%). Twenty-six donors (25.5%) took a psychologically defensive attitude (T-score of K scale ≥65) during the pre-donation evaluation. Psychologically defensive donors expressed a significantly lower level of concern about liver donation compared to non-defensive donors (P<0.01).

Conclusions

We need to pay more attention to the family-related issues and psychological defensiveness of living liver donor candidates when evaluating psychosocial status before LDLT.

Current Status of Living Donor Liver Transplantation in the United States

Adult-to-adult living donor liver transplantation (LDLT) was introduced in response to the shortage of deceased donor liver grafts. The number of adult living donor transplants is increasing due to improved outcomes and increasing need. Advantages of LDLT include optimization of the timing of transplant, better organ quality, and lower rates of recipient mortality compared to staying on the wait list for deceased donor liver transplant. Donor safety remains the major focus when considering LDLT. Recent advancements have supported the increased use of LDLT to help decrease wait list death and improve long-term survival of transplant recipients.

Prevalence and Predictors of Patient-Reported Long-term Mental and Physical Health After Donation in the Adult-to-Adult Living-Donor Liver Transplantation Cohort Study

BACKGROUND

Prospective and longitudinal studies have examined liver donors' medical outcomes beyond the first 1 to 2 years postdonation. There is no analogous longitudinal evidence on long-term psychosocial outcomes, including patient-reported clinically significant mental health problems and perceptions of physical well-being. We examined prevalence, descriptive characteristics, and predictors of diagnosable mental health conditions and self-reported physical health problems, including fatigue and pain, in the long-term years after liver donation.

METHODS

Donors from 9 centers who initially completed telephone interviews at 3 to 10 years postdonation (mean, 5.8 years; SD, 1.9) were reinterviewed annually for 2 years using validated measures. Outcomes were examined descriptively. Repeated-measures regression analyses evaluated potential predictors and correlates of outcomes.

RESULTS

Of 517 donors initially interviewed (66% of those eligible), 424 (82%) were reassessed at least once. Prevalence rates of major depression and clinically significant pain were similar to general population norms; average fatigue levels were better than norms. All prevalence rates showed little temporal change. Anxiety and alcohol use disorder rates exceeded normative rates at 1 or more assessments. Longer postdonation hospitalization, female sex, higher body mass index, concerns about donation-related health effects, and burdensome donation-related financial costs were associated with increased risk for most outcomes (P's < 0.05). Men were at higher risk for alcohol use disorder (P < 0.001).

CONCLUSIONS

Anxiety and alcohol use disorders were more common than would be expected; they may warrant increased research attention and clinical surveillance. Surveillance for long-term problems in the areas assessed may be optimized by targeting donors at higher risk based on identified predictors and correlates.

Fatigue, Pain, and Other Physical Symptoms of Living Liver Donors in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study

Little is known about living liver donors' perceptions of their physical well-being following the procedure. We collected data on donor fatigue, pain, and other relevant physical outcomes as part of the prospective, multicenter Adult-to-Adult Living Donor Liver Transplantation Cohort Study consortium. A total of 271 (91%) of 297 eligible donors were interviewed at least once before donation and 3, 6, 12, and 24 months after donation using validated measures when available. Repeated measures regression models were used to identify potential predictors of worse physical outcomes. We found that donors reported more fatigue immediately after surgery that improved by 2 years after donation, but not to predonation levels. A similar pattern was seen across a number of other physical outcomes. Abdominal or back pain and interference from their pain were rated relatively low on average at all study points. However, 21% of donors did report clinically significant pain at some point during postdonation study follow-up. Across multiple outcomes, female donors, donors whose recipients died, donors with longer hospital stays after surgery, and those whose families discouraged donation were at risk for worse physical well-being outcomes. In conclusion, although not readily modifiable, we have identified risk factors that may help identify donors at risk for worse physical outcomes for targeted intervention.

Status of Adult Living Donor Liver Transplantation in the United States: Results from the Adult-To-Adult Living Donor Liver Transplantation Cohort Study

This article reviews the Adult-to-Adult Living Donor Liver Transplant Cohort Study (A2ALL). The findings show that the number of adult-to-adult living donor liver transplants is consistently increasing. Living donor liver transplantation has an important benefit for patients with acute liver failure, does not compromise donor safety, and has lower rates of acute cellular rejection in biologically related donor and recipient. The conclusions from the A2ALL consortium have been critical in transplant advancement, supporting increased use to help decrease waitlist death and improve long-term survival of transplant recipients.
