Background: Anastomotic biliary strictures (BSs) are among the most common complications after liver transplantation (LT), accounting for 5–15% of adult recipients after deceased-donor transplantation. For some reason, this percentage increased in our center in recent years, and the goal of this study was to find out the reasons behind this to avoid this complication in the future. Material and Methods: We retrospectively analyzed the occurrence of anastomotic biliary strictures in 230 cadaveric-donor LTs performed in our center between January 2019 and December 2023. Many variables related to the donor, recipient, and surgical procedure were compared between patients who experienced BS and those without this complication. Statistical analysis was performed using Fisher’s exact test, a one-way ANOVA test, and Pearson’s correlation coefficient. Results: Altogether, 51 patients (22.17%) developed BSs. This percentage was especially high in 2023 (32%). The only significant differences found in study group compared to the control group were the requirement of additional doses of vasopressors during surgery (45 (86.53%) vs. 138 (77.09%), p = 0.0001) and more frequent instances of reperfusion syndrome (8/51 (15.68%) vs. 11/179 (6.11%), p = 0.00001). Conclusions: We conclude that ischemia during LT has an advantage over technical parameters in the development of BSs after LT. Appropriate blood volume resuscitation as opposed to inotropic treatment may reduce the risk of this complication....
Introduction: Curative treatment of HCC can be achieved by liver transplantation. In the framework of transplantation, add-on transarterial chemoembolization (TACE) can be performed as bridging therapy for local tumor control. The association between TACE and an increased incidence of hepatic arterial complications after transplantation has been investigated in multiple research items; however, the exact association remains unclear. The aim of this report was to explore the role of pre-transplantation TACE and pre-existing vascular celiac pathologies on the occurrence of postoperative hepatic arterial complications. Methods: This retrospective single-center study included all patients who underwent liver transplantation between 2008 and 2020. Arterial complication was defined as any postoperative occlusion, stenosis >50%, dissection or aneurysm on cross-sectional imaging. Results: This study encompasses 109 patients after transplantation, of which 80 underwent TACE prior to transplantation. The overall incidence of postoperative arterial complications did not differ between the groups (TACE 8/80 vs. control 6/29, p = 0.19). Further analysis showed no significant differences in the occurrence of specific complications (Occlusion: TACE 9/80 vs. control 3/29, p = 0.56; Stenosis: TACE 4/80 vs. control 5/29, p = 0.05; Dissection: TACE 1/80 vs. control 1/29; p = 0.46). Furthermore, linear regression analysis for preoperative TACE therapy, anatomic variants and pre-existing pathologies of the hepatic vasculature showed no association with postoperative arterial complications. Conclusions: Preoperative TACE therapy showed no influence on the incidence of post-transplant arterial complications in patients after liver transplantation. Furthermore, preoperative TACE therapy as well as anatomic variants and pre-existing arterial pathologies of the celiac axis could not be identified as risk factors for complications at the arterial anastomotic site after transplantation....
Background/Objectives: Since their introduction in the 1990s, the Milan criteria have been the gold standard of indication for liver transplantation (LT) in patients with hepatocellular carcinoma (HCC). Nevertheless, several institutions have reported wider indication criteria for LT with comparable survival outcomes. Methods: This paper summarizes the recent indications for LT for HCC through a literature review. Results: There are several criteria expanding the Milan criteria, which can be subdivided into the “based on tumor number and size only”, “based on tumor number and size plus tumor markers”, and “based on tumor differentiation” groups, with the outcomes being comparable to those of patients included within the Milan criteria. Besides the tumor size and number, which are included in the Milan criteria, recent criteria included biomarkers and tumor differentiation. Several retrospective studies have reported microvascular invasion (MVI) as a significant risk factor for postoperative recurrence, highlighting the importance of preoperatively predicting MVI. Several studies attempted to identify preoperative predictive factors for MVI using tumor markers or preoperative imaging findings. Patients with HCC who are LT candidates are often treated while on the waiting list to prevent the progression of HCC or to reduce the measurable disease burden of HCC. The expanding repertoire of chemotherapeutic regiments suitable for patients with HCC should be further investigated. Conclusions: There are several criteria expanding Milan criteria, with the outcomes being comparable to those of patients included within the Milan criteria....
Living kidney transplantation yields better outcomes for recipients than deceased donation, though it may present long-term challenges for donors. This study assessed the quality of life (QoL) of living kidney donors in Greece using the SF-36 questionnaire and examined associated sociodemographic and clinical factors. This cross-sectional study included 242 clinically stable kidney donors from Laiko General Hospital’s Kidney Donor Outpatient Clinic in Athens. Data on demographics, comorbidities, laboratory parameters, and QoL were collected. Spearman’s correlation coefficients were used to identify associations between QoL scores and influencing factors. The majority of donors were female (73.55%). Donors reported high QoL, with median PCS and MCS scores of 55.27 (49.08–57.73) and 54.17 (46.64–59.93), respectively. Male donors had higher PCS and MCS scores than females (p = 0.028 and p = 0.004). Laparoscopic nephrectomy was associated with better mental health and physical outcomes compared to open surgery (p < 0.001). Higher education and eGFR correlated with better PCS scores, while older age negatively affected QoL (p < 0.05). Living kidney donors reported a satisfactory level of overall QoL post-donation. Lower QoL scores were correlated with the female gender, older age, and open nephrectomy. These findings may further reinforce support for our current organ donation policy. Non-modifiable factors appear to influence donor quality of life. These findings reinforce the current organ donation policy while emphasizing the need for careful pre-transplant counseling and ongoing monitoring post-donation....
Background: Cardiac allograft vasculopathy (CAV) is an accelerated form of coronary artery disease (CAD) that is characterized by concentric fibrous intimal hyperplasia along the length of coronary vessels, and is recognized as long-term complication after heart transplantation. The chromosomal loci 9p21, 6q25.1, and 2q36.3, represented by their respective leading variants rs10757274, rs6922269 and rs2943634, have been linked with a history of CAD by genome-wide association studies. We aimed to investigate the associations of genetic variants at the loci 9p21, 6q25.1, and 2q36.3 with CAV as genetic risk factors for early prediction. Methods: Genomic DNA was extracted from paired aortic samples of 727 heart recipients (average age 50.8 ± 12.2 years; 21.3% women) and corresponding donors (average age 39.7 ± 12.0 years; 26.1% women). The variants within the loci 9p21, 6q25.1, and 2q36.3 were genotyped using PCR-RFLP. Results: The recipients’ variants of 9p21 (OR 1.97; 95% CI, 1.21-3.19 for GG vs. +A comparison, p = 0.0056) and 2q36.3 (OR 2.46; 95% CI, 1.12–6.17 for +C vs. AA comparison, p = 0.0186) were associated with higher incidence of CAV during the first year following heart transplantation. No such association was found for donor genotypes. Conclusions: Our data suggest that variants at the locus 9p21 (rs10757274) and 2q36.3 (rs2943634) are associated with early CAV development....
