Post-Operative Complications in Living Liver Donors: A Single-Center Experience in China

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.

Living donor hepatectomy in medium volume liver transplant centre has comparable outcomes to high volume centres: validation of donabedian quality assurance framework

BACKGROUND

Given the complexity of living donor hepatectomy, it is expected that high hospital volume will better outcomes. This study aims to evaluate post-operative outcomes for living donor hepatectomy in a medium volume liver transplant centre and compare to outcomes in high volume centres. Also, it serves as a validation tool for framework of structure-process-outcome model for safe living donor hepatectomy program.

METHODS

204 donors who underwent donor hepatectomy between June 1996 to September 2019 were reviewed retrospectively and compared to outcomes in high volume centres.

RESULTS

At 6 months, overall donor morbidity rate was 20/204 (9.8%). Wound complications were most common at 5/204 (2.5%). Majority of complications were either Clavien grade 1 or 2 and only 3 donors had Clavien grade 3 complications. There was zero donor mortality.

DISCUSSION

Our centre's donor morbidity rate of 9.8% is the one of the lowest reported in the published literature. With increased experience, stringent donor selection and enhanced perioperative care by a multi-disciplinary team, outcomes in a medium volume centre can match the outcomes reported in high volume centres. The framework for quality in terms of structure, process and outcomes is presented which can be adopted for developing programs.

Health-Related Quality of Life in Predominantly Young Parental Living Liver Donors: A Cross-Sectional Study in China

Objective: The health-related quality of life (HRQoL) of donors deserves attention and must be considered for a long time. Many of the published studies had small sample sizes, and research from mainland China, in particular, is scant. Thus, this study aimed to investigate the HRQoL of living liver donors and identify the influencing factors of the HRQoL in mainland China.

Methods: This is a cross-sectional study. The data were collected from the liver transplantation center, the Tianjin First Center Hospital, China. Living liver donors older than 18 years and at a minimum of 1-month, post-donation was included. The HRQoL was evaluated using the Medical Outcome Study Short form 36 (SF-36). Sociodemographic and clinical-related variables, HRQoL status, and its potential impact factors were analyzed.

Results: A total of 382 living liver donors completed the survey. The median number of months post-donation was 25, and parental donors (99.2%) were the most frequent relationship. The majority of the participants (372, 97.4%) donated their left lateral lobes. Thirty-two (8.4%) donors suffered complications, and of them, 7 suffered from biliary leakage (1.8%), which was the most common one in this study. The physical functioning (PF), role–physical (RP), bodily pain (BP), general health (GH), social functioning (SF), role–emotional (RE), and mental health (MH) scores among the living liver donors were significantly better than those of the Chinese norms. Short-time post-donation [odds ratio (OR): 0.008; p < 0.001] and male recipients (OR:0.195; p = 0.024) were associated with the likelihood of a poor physical related quality of life.

Conclusions: Despite, in general, good HRQoL outcomes, we also believed that liver donation has an obvious influence on the physical functions of liver donors. More attention and long-term follow-ups are necessary for donors at higher risk based on identified influencing factors and correlates.

Liver Transplantation: A 10-Year Low-Volume Transplant Center Experience in Kazakhstan

Background

Liver transplantation is considered to be the best available treatment option for patients with liver failure. In Kazakhstan, the liver transplantation program was established a decade ago. In this study, we analyzed a low-volume transplant center experience of liver transplantation in Kazakhstan.

Material/Methods

Clinical data of the 64 consecutive liver transplantations from deceased and living donors between 2010 and 2020 were retrieved from electronic records. All data were retrospectively analyzed.

Results

A total of 64 liver transplantations, 11 from deceased donors and 53 from living donors, were carried out in our center between 2010 and 2020. The mean age of the recipient was 44 years, 53% were female, and 47% were male. Hepatitis B+hepatitis D infection was the most common cause of end-stage liver disease (21 cases; 32.8%). The overall patient survival rates for 1, 3, and 5 years were 75%, 69.5%, and 59.6%, respectively, for recipients of a liver transplant from a living donor and 54.5%, 45.5%, and 39% for recipients of a liver transplant from a deceased donor.

Conclusions

Our clinical outcomes had a high rate of biliary and vascular complications that led to a low survival rate of the recipients. Starting the transplant program in Kazakhstan faced various challenges. In the early period, most transplantations were performed in collaboration with or under the guidance of transplant teams from Russia, Turkey, and South Korea. Improving surgical techniques and protocols of pre- and posttransplantation management could reduce the complications after transplantation.

Respiratory Complications Among Living Liver Donors: A Single-Center Retrospective Observational Study

OBJECTIVES

The safety of living liver donors is considered a high priority. In this study, we aimed to highlight the incidence and risk factors of respiratory complications among living liver transplant donors at our institute.

MATERIALS AND METHODS

We evaluated data of 178 related living liver donors who were seen from January 2014 to December 2018. We recorded significant respiratory complications, such as pulmonary embolism, pleural effusion, pneumothorax, pneumonia, acute lung injury, acute respiratory distress syndrome, and transfusion-related acute lung injury. Complications were noted as clinically evident and/or needing intervention. We also recorded the frequency of nonrespiratory complications and duration of intensive care unit and hospital stays.

RESULTS

Ten donors (5.6%) developed significant respiratory complications: 2 (1.1%) had pulmonary embolisms, 3 (1.7%) developed symptomatic pleural effusion that required thoracentesis, and 4 (2.25%) had chest infections. The remaining donor (0.6%) had unexplained respiratory insufficiency. Logistic regression analyses identified age ≥ 35 years and previous surgery as the main risk factors of significant respiratory complications. There were no recorded cases of pneumothorax, acute lung injury, acute respiratory distress syndrome, and transfusion-related acute lung injury. Raw surface collection (14.6%) and biliary leakage (7.9%) were the most frequent nonrespiratory complications. There was no significant difference between patients with and without significant respiratory complications with regard to intensive care unit and hospital stays.

CONCLUSIONS

Despite the low incidence of significant respiratory complications among our living liver donor cohort, close monitoring and early management are essential to achieve better prognosis, especially in donors older than 35 years or those with previous surgery.

Donors' Quality of Life after Living Donor Liver Transplantation: Shiraz Organ Transplant Center Experience

BACKGROUND

Probable effects of living donor liver transplantation on the wellbeing of the donor and psychological difficulties are necessary to be understood.

OBJECTIVE

To assess the quality of life of living donors after liver donation.

METHODS

140 living donors who underwent hepatectomy between 2012 and July 2015 were enrolled in this study. Donors were asked to complete the Short Form 36-question Health Survey (SF-36) through face to face or by telephone interview.

RESULTS

The mean±SD age of donors at transplantation was 32.1±7.3 years; 83 (59.3%) of donors were female. 134 (95.7%) were married. The mean±SD BMI was 23.8±3.5 (kg/m²). "Mother-to-child" was the most frequent relationship (n=79, 56.4%). 22 (15.7%) complications were reported by participants. The mean±SD score of Physical Component Summary and Mental Component Summary were 48.8±14.6 and 50.1±6.9, respectively.

CONCLUSION

Most living donors sustain a near average quality of life post-donation. It seems that living donation does not negatively affect the quality of life.

Early postoperative hypoalbuminaemia is associated with pleural effusion after donor hepatectomy: A propensity score analysis of 2316 donors

Pleural effusion and hypoalbuminaemia frequently occur after hepatectomy. Despite the emphasis on the safety of donors, little is known about the impact of postoperative albumin level on pleural effusion in liver donors. We retrospectively assessed 2316 consecutive liver donors from 2004 to 2014. The analysis of donors from 2004 to 2012 showed that postoperative pleural effusion occurred in 47.4% (970/2046), and serum albumin levels decreased until postoperative day 2 (POD2) and increased thereafter. In multivariable analysis, the lowest albumin level within POD2 (POD2ALB) was inversely associated with pleural effusion (OR 0.28, 95% CI 0.20-0.38; P < 0.001). POD2ALB ≤3.0 g/dL, the cutoff value at the 75th percentile, was associated with increased incidence of pleural effusion after propensity score (PS) matching (431 pairs; OR 1.69, 95% CI 1.30-2.21; P < 0.001). When we further analysed data from 2010 to 2014, intraoperative albumin infusion was associated with higher POD2ALB (P < 0.001) and lower incidence of pleural effusion (P = 0.024), compared with synthetic colloid infusion after PS matching (193 pairs). In conclusion, our data showed that POD2ALB is inversely associated with pleural effusion, and that intraoperative albumin infusion is associated with a lower incidence of pleural effusion when compared to synthetic colloid infusion in liver donors.

Donor Safety in Adult-Adult Living Donor Liver Transplantation: A Single-Center Experience of 356 Cases

Background

As an important means to tackle the worldwide shortage of liver grafts, adult-adult living donor liver transplantation (A-ALDLT) is the most massive operation a healthy person could undergo, so donor safety is of prime importance. However, most previous research focused on recipients, while complications in donors have not been fully described or investigated.

Material/Methods

To investigate donor safety in terms of postoperative complications, the clinical data of 356 A-ALDLT donors in our center from January 2002 to September 2015 were retrospectively analyzed. These patients were divided into a pre-2008 group (before January 2008) and a post-2008 group (after January 2008). Donor safety was evaluated with regard to the type, frequency, and severity of postoperative complications.

Results

There were no donor deaths in our center during this period. The overall complication rate was 23.0% (82/356). The proportion of Clavien I, II, III, and IV complications was 51.2% (42/82), 25.6% (21/82), 22.0% (18/82), and 1.2% (1/82), respectively. In all the donors, the incidence of Clavien I, II, III, and IV complications was 11.8% (42/356), 5.9% (21/356), 5.1% (18/356), and 0.3% (1/356), respectively. The overall complication rate in the post-2008 group was significantly lower than that in the pre-2008 group (18.1% (41/227) vs. 32.6% (42/129), P<0.01). Biliary complications were the most common, with an incidence of 8.4% (30/356).

Conclusions

The risk to A-ALDLT donors is controllable and acceptable with improvement in preoperative assessment and liver surgery.
