RESUMEN

OBJECTIVES: De novo malignancies are the most common cause of death after solid-organ transplant. Here, we aimed to summarize standard incidence ratios of de novo malignancies after liver and kidney transplant within the same geographical locations, compare these ratios among differenttypes of de novo malignancies after liver and kidney transplant, and elucidate differences in de novo malignancies between liver and kidney transplant recipients. MATERIALS AND METHODS: We performed a systematic review to identify studies on standard incidence ratios of de novo malignancies after liver and kidney transplant in the United Kingdom, Sweden, South Korea, and Taiwan. RESULTS: Four articles reported standard incidence ratios of de novo malignancies in 14 016 liver transplant recipients (mean follow-up 4.3 ± 0.7 y) and 48179 kidney transplant recipients (mean follow-up 6.1 ± 2.1 y). Mean ratios of oropharyngeal, pulmonary, colorectal, renal, and breast malignancies were 5.3, 1.6, 1.9, 1.8, and 1.1,respectively, after liver transplant and 3.2, 1.7, 1.5, 17.0, and 1.3, respectively, after kidney transplant. Mean ratios of bladder, cervixuterus, and stomach de novo malignancies were 1.8, 2.0, and 2.9, respectively, after liver transplant and 13.0, 1.9, and 1.9,respectively, after kidney transplant. Mean ratios of prostatic and esophageal malignancies were 1.6 and 1.8 after liver transplant and 1.2 and 1.1 after kidney transplant. Mean ratio of ovarian cancer was 1.2 and 2.9, respectively, after liver and kidney transplant. CONCLUSIONS: Low-frequency and lower standard incidence ratios were observed for testicular, ovarian and central nervous system malignancies after kidney and liver transplant. Standard incidence ratios of oropharyngeal and hepatic malignancies were higher after liver transplant compared with kidney transplant. After kidney transplant, standardized ration for renal malignancy were 9.4 times and bladder malignancies were 7.2 times higher compared with liver transplant recipients.

RESUMEN

OBJECTIVES: Donor hepatectomy is a major surgery with a relatively safeprofile anda reportedcomplication rate of ~20%. Most complications are non-life threatening and are resolved with conservative measures. However, rare complications may need invasive precautions, ranging from percutaneous interventions to surgeries. MATERIALS AND METHODS: We retrospectively analyzed all living donor hepatectomies at our center. Donors were divided into 2 groups: laparoscopic and open procedures. We collected preoperative, intraoperative and postoperative data of donors.Donor complications were recorded separately intraoperatively and postoperatively according to the Clavien-Dindo postoperative complication classification system. RESULTS: Between July 2018 and April 2023, 215 living donors had hepatectomies, including 48 laparoscopic and 167 open donor hepatectomies. Among donors, 91 were female donors (42.3%) and 124 were male donors (57.7%).The meanage of alldonorswas 33.5±8.1 years, and the mean body mass index (in kilogram divided by meters squared) was 24.6 ± 3.8. Among donors, 124 underwent right and 91 underwent left or left lateral hepatectomies. The mean operative time for all donors was 301 ± 83 minutes, the mean hospital stay was 5.8 ± 1.4 days, and the mean follow-up was 31.9 ± 15.8 months. Four patients (1.8%) had intraoperative complications, including 2 cases of bleeding, 1 diaphragm perforation, and 1 portal vein stenosis. Fourteen patients (7.4%) had major postoperative complications, with 5 patients requiring surgical intervention. CONCLUSIONS: Donor hepatectomy is a complicated surgery that requires extensive preoperative preparation and appropriate donor selection. Postoperative donor complications can be diagnosed early with close follow-up, and a multidisciplinary approach is essential for complication management.

RESUMEN

OBJECTIVES: The proportion of older transplant recipients has increased. Cognitive impairment is not rare after kidney transplant, but data on this issue in liver transplant recipients are scarse. MATERIALS AND METHODS: In this cross-sectional study, we evaluated all liver transplant recipients from a single center in Brazil from July 2018 to June 2020 in terms of cognitive performance to determine the prevalence of neurocognitive disorder. We compared liver transplant recipients with neurocognitive disorder with liver transplant recipients without neurocognitive disorder. We also compared those with an alcoholic cause of liver transplant with other patients. The presence of depressive symptoms was assessed. We performed correlations of clinical data with cognitive scores. RESULTS: In a sample of 100 recipients with median age of 62 years (interquartile range, 56.2-69 y), neurocognitive disorder was present in 21% of the group. Patients with cognitive impairment were older (68 y [61-72] vs 61 y [52-68]; P = .019) and had a trend to higher proportion of persistent kidney injury (33.3% vs 13.9%; P = .055) versus patients without cognitive impairment. Recipients with alcoholic cause of liver transplant exhibited worse cognitive performance in the Mini-Mental State Examination (score of 26 [23.7-28.2] vs 28 [26-29]; P = .024) and the Alzheimer Disease Assessment Scale-cognitive (score of 10.4 [8.6-14.2] vs 8 [6.3-10]; P = .008) than other patients. Weak negative correlations were shown in cognitive performance scores versus recipient age (Semantic Verbal Fluency test, r = -0.334 [P = .001]; Clock Drawing test, r = -0.209 [P = .037]; Alzheimer Disease Assessment Scale-cognitive, r = -0.323 [P = .001]). CONCLUSIONS: Neurocognitive disorder was common in liver transplant recipients, in part due to increased age. This study also suggested a role for alcoholic cause of liver transplant and persistent kidney injury in the development of cognitive impairment.

RESUMEN

INTRODUCTION: Sarcopenia is common in children after liver transplantation (LTx). Resistance training (RT) may be effective in combating sarcopenia. OBJECTIVES: The purpose of the study was to test the feasibility and impact of a 12-week RT program on skeletal muscle mass (SMM), muscle strength, physical performance (PP), and child-parent perspectives about RT. METHODS: Children (6-18 years) post-LTx and healthy controls (HC) underwent progressive RT using resistance bands. SMM and adipose tissue (MRI: abdomen and thigh), muscle strength (handgrip, push-ups, sit-to-stand), and PP (6-minute walk test [6MWT], timed-up-and-down-stair test [TUDS]) were measured before and after 12-weeks of RT. RESULTS: Ten children post-LTx (11.9 ± 3.5 years) and 13 HC (11.7 ± 3.9 years) participated. LTx children significantly increased abdominal SM-index (+4.6% LTx vs. a -2.7% HC; p = 0.01) and decreased visceral adipose tissue-index (-18% LTx vs. -0.8% HC; p = 0.04) compared to HC. No thigh SMI changes were noted. Significant increases in 6MWT distance (LTx; p = 0.04), number of push-ups (p = 0.04), and greater reduction times for TUDS (-10.6% vs. +1.7%; p = 0.05) occurred after 12 weeks. Higher thigh muscle-fat content was associated with worse physical performance. These results were impacted by adherence (≥75% vs. <75%) and family engagement. CONCLUSIONS: RT in children post-LTx is feasible and effective. RT in children post-LTx may alleviate adverse outcomes associated with sarcopenia.

RESUMEN

OBJECTIVES: Primary sclerosing cholangitis is an autoimmune illness affecting the intrahepatic and/or extrahepatic bile ducts that has a varying clinical history and no clear therapy. Recurrence of primary sclerosing cholangitis after transplantation can cause recurring liver failure, decreased survival, and the necessity for retransplant. Here, we explored the incidence of recurrence while also identifying the risk factors of primary sclerosing cholangitis. MATERIALS AND METHODS: In this retrospective cohort study, we collected demographic and clinical data from patients with a history of primary sclerosing cholangitis after liver transplant between 2011 and 2021. With SPSS software, we compared results in 2 groups of patients (with and without recurrent sclerosing biliary cholangitis) in terms of demographic and clinical variables. RESULTS: The study included 408 patients. Lower donor age and the occurrence of acute cellularrejection were shown to be key risk factors for recurrence of primary sclerosing cholangitis. Acute cellularrejection showed the best likelihood of predicting primary sclerosing cholangitis recurrence. As the number of acute cellular rejection episodes increased, so did the chance of primary sclerosing cholangitis. Death rate of patients with recurrence of primary sclerosing cholangitis was 40.8% (n = 20 patients) compared with 18.9% (n = 68 patients) in those without recurrence (significant at P < .001). CONCLUSIONS: The recurrence of primary sclerosing cholangitis had a detrimental effect on survival after liver transplant. Modifiable risk variables have the potentialto affecttherapies on care and prevention of primary sclerosing cholangitis recurrence. Donor age and acute cellular rejection were risk factors for decreased survival and higher primary sclerosing cholangitis recurrence. The use of mycophenolate (Cellcept) increased recurrence, but tacrolimus reduced mortality.

RESUMEN

BACKGROUND: The effects of anesthetics on liver and kidney functions after infantile living-related liver transplantation (LRLT) are unclear. This study aimed to investigate the effects of propofol-based total intravenous anesthesia (TIVA) or desflurane-based inhalation anesthesia on postoperative liver and kidney functions in infant recipients after LRLT and to evaluate hepatic ischemia-reperfusion injury (HIRI). METHODS: Seventy-six infants with congenital biliary atresia scheduled for LRLT were randomly divided into two anesthesia maintenance groups: group D with continuous inhalation of desflurane and group P with an infusion of propofol. The primary focus was to assess alterations of liver transaminase and serum creatinine (Scr) levels within the first 7 days after surgery. And the peak aminotransferase level within 72 h post-surgery was used as a surrogate marker for HIRI. RESULTS: There were no differences in preoperative hepatic and renal functions between the two groups. Upon the intensive care unit (ICU) arrival, the levels of aspartate aminotransferase (AST, P = 0.001) and alanine aminotransferase (ALT, P = 0.005) in group P were significantly lower than those in group D. These changes persisted until the fourth and sixth days after surgery. The peak AST and ALT levels within 72 h after surgery were also lower in group P than in group D (856 (552, 1221) vs. 1468 (732, 1969) U/L, P = 0.001 (95% CI: 161-777) and 517 (428, 704) vs. 730 (541, 1100) U/L, P = 0.006, (95% CI: 58-366), respectively). Patients in group P had lower levels of Scr upon the ICU arrival and on the first day after surgery, compared to group D (17.8 (15.2, 22.0) vs. 23.0 (20.8, 30.8) µmol/L, P < 0.001 (95% CI: 3.0-8.7) and 17.1 (14.9, 21.0) vs. 20.5 (16.5, 25.3) µmol/L, P = 0.02 (95% CI: 0.0-5.0) respectively). Moreover, the incidence of severe acute kidney injury was significantly lower in group P compared to that in group D (15.8% vs. 39.5%, P = 0.038). CONCLUSIONS: Propofol-based TIVA might improve liver and kidney functions after LRLT in infants and reduce the incidence of serious complications, which may be related to the reduction of HIRI. However, further biomarkers will be necessary to prove these associations.

RESUMEN

BACKGROUND This study aimed to evaluate the effectiveness of implementing evidence-based preoperative nursing interventions in reducing postoperative infections and intensive care unit (ICU) length of stay among liver transplant recipients. MATERIAL AND METHODS A controlled study was conducted, comparing postoperative outcomes between an intervention group receiving standardized, evidence-based preoperative care and a control group receiving routine preoperative care. Patients undergoing elective liver transplantation from September 2020 to March 2021 were included and assigned to either the intervention or control group. The intervention group received preoperative interventions based on best available evidence, while the control group received standard preoperative care. The primary outcomes measured were postoperative infection rates and length of ICU stay. RESULTS In the control group the overall Intensive Care Unit (ICU) length of stay was 3 days and the infection rate was 33.30%, while in the intervention group it was 3 days and 13.80% (P<0.05). There was no significant difference in the length of ICU stay between the control and the intervention groups (P>0.05). There was a significant improvement in the awareness, acceptance, and compliance of doctors and nurses. CONCLUSIONS Using the best evidence-based intervention for preoperative nursing of liver transplantation patients can standardize preoperative nursing behavior. Although we did not find significant differences in outcomes before and after the intervention, it is necessary to prevent postoperative infection and improve nursing compliance.

RESUMEN

Dysnatremia is common in donors and recipients of liver transplantation (LT). However, the influence of dysnatremia on LT prognosis remains controversial. This study aimed to investigate effects of donors' and recipients' serum sodium on LT prognosis. We retrospectively reviewed 248 recipients who underwent orthotopic LT at our center between January 2016 and December 2018. Donors and recipients perioperative and 3-year postoperative clinical data were included. Delta serum sodium was defined as the donors' serum sodium minus the paired recipients' serum sodium. Donors with serum sodium > 145 mmol/L had significantly higher preoperative blood urea nitrogen (BUN) (P < 0.01) and creatinine (Cr) (P < 0.01) than others. Preoperative total bilirubin (TBIL) (P < 0.01), direct bilirubin (DBIL) (P < 0.01), BUN (P < 0.01), Cr (P < 0.01) were significantly higher in the hyponatremia group of recipients than the other groups, but both of donors' and recipients' serum sodium had no effect on the LT prognosis. In the delta serum sodium < 0 mmol/L group, TBIL (P < 0.01) and DBIL (P < 0.01) were significantly higher in postoperative 1 week than the other groups, but delta serum sodium had no effect on the postoperative survival rates. Dysnatremia in donors and recipients of LT have no effect on postoperative survival rates, hepatic and renal function, but recipients with higher serum sodium than donors have significantly higher TBIL and DBIL at 1 week postoperatively.

RESUMEN

Since the first published report of experimental kidney transplantation in dogs in 1902, there were many experimental and clinical trials of organ transplantation, with many sacrifices. After the establishment of the surgical technique and the discovery of immunosuppressive drugs, transplantation became the definitive treatment strategy for patients with terminal organ failure. However, this is not a common therapy method due to the difficulty of solving the fundamental issues behind organ transplantation, including the shortage of donor graft, potential risks of transplant surgery and economic capability. The pre- and post-transplant management of recipients is another critical issue that may affect transplant outcome. Most liver transplant recipients experience post-transplant complications, including infection, acute/chronic rejection, metabolic syndrome and the recurrence of hepatocellular carcinoma. Therefore, the early prediction and diagnosis of these complications may improve overall and disease-free survival. Furthermore, how to induce operational tolerance is the key to achieving the ultimate goal of transplantation. In this review, we focus on liver transplantation, which is known to achieve operational tolerance in some circumstances, and the mechanical similarities and differences between liver transplant immunology and fetomaternal tolerance, autoimmunity or tumor immunity are discussed.

RESUMEN

BACKGROUND: Sarcopenia is a complication that occurs after liver transplantation (LT), and it is a poor prognostic factor. METHODS: A total of 23 healthy controls and 131 LT patients (18 - 76 weeks of age) were enrolled in the study. Pa-tients were grouped according to the North American Working Group on Sarcopenia in Liver Transplantation by performing pre- and post-transplant CT scans of the third lumbar (L3). The serum C-reactive protein (CRP) was analyzed and the liver frailty index (LFI) was assessed. Their associations with postoperative sarcopenia, skeletal muscle index (SMI), and poor outcomes were examined. RESULTS: Before LT, the serum CRP was increased in patients with LT, compared with the healthy subjects, and had the highest levels in patients with sarcopenia. There were seventy-nine patients with sarcopenia after LT, including 48 who had been diagnosed with sarcopenia preoperatively and 31 who had a new onset of sarcopenia after LT. There was a moderate-strength negative correlation between the preoperative and postoperative rates of change in CRP and L3 SMI. Patients assessed as frail preoperatively (LFI ≥ 4.5) were associated with postoperative sarcopenia, and 19 of the new postoperative sarcopenia cases occurred in patients assessed as frail preoperatively. The serum CRP levels and LFI were significantly higher in patients who experienced a prolonged hospitalization and early infections postoperatively than in patients without significant adverse events. CRP (post-LT) > 2.575 pg/mL (OR = 1.16, 95% CI: 1.06 - 2.39, p = 0.026) as well as frailty (OR = 1.36, 95% CI: 1.20 - 2.60, p = 0.001) were independent predictors of sarcopenia after LT in patients. CONCLUSIONS: Serum CRP levels and LFI may be effective for an early detection of sarcopenia in patients with LT.

RESUMEN

PURPOSE: Evaluate cytomegalovirus (CMV) post-prophylaxis surveillance in high-risk (D+/R-) kidney and liver transplant recipients. METHODS: Adult D+/R- patients were included if transplanted between 6/1/15 and 11/30/22 and divided into a pre-CMV-stewardship-era (6/1/15-5/31/18), CMV-stewardship-era (6/1/18-6/30/20), and a surveillance-era (7/1/2020-11/30/2022) then followed through 12 months. The primary objective was to evaluate CMV-related outcomes. The secondary objective was to assess graft and patient survival by era. RESULTS: There were 328 patients in the study period; 133 in the pre-stewardship-era, 103 in the stewardship-era, and 92 in the surveillance-era. Replication rates in the surveillance-era were significantly higher, as anticipated due to increased sampling (pre 38.4%, stewardship 33.0%, surveillance 52.2%, p = 0.02). Time from transplant to first replication was similar (pre 214.0 ± 79.0 days, stewardship 231.1 ± 65.5, surveillance 234.9 ± 61.4, p = 0.29). CMV viral load (VL) at first detection, maximum-VL, and incidence of VL > 100 000 IU/mL were numerically lower in the surveillance era, although not statistically significant. CMV end-organ disease (p < 0.0001) and ganciclovir-resistance (p = 0.002) were significantly lower in the surveillance era than in both previous eras. Rejection was not different between eras (p = 0.4). Graft (p = 0.0007) and patient survival (p = 0.008) were significantly improved in the surveillance era. CONCLUSIONS: Post-prophylaxis surveillance significantly reduced CMV end-organ disease and resistance. Despite observing increased replication rates in the surveillance era, rejection was not significantly different and there was no graft loss or patient mortality at 12 months.

RESUMEN

INTRODUCTION: Liver transplantation (LT) is a well-established method applied for the treatment of various liver diseases, including primary and secondary malignancies, as well as acute liver failure triggered by different mechanisms. In turn, liver failure (PHLF) is the most severe complication observed after liver resection (LR). PHLF is an extremely rare indication for LT. The aim of the present study was to assess the results of LT in patients with PHLF. METHODS: Relevant cases were extracted from the prospectively collected database of all LTs performed in our center. All clinical variables, details of the perioperative course of each patient and long-term follow-up data were thoroughly assessed. RESULTS: Between January 2000 and August 2023, 2703 LTs were carried out. Among them, six patients underwent LT for PHLF, which accounted for 0.2% of all patients. The median age of the patients was 38 years (range 24-66 years). All patients underwent major liver resection before listing for LT. The 90-day mortality after LT was 66.7% (4 out of 6 patients), and all patients experienced complications in the posttransplant course. One patient required early retransplantation due to primary non-function (PNF). The last two transplanted patients are alive at 7 years and 12 months after LT, respectively. CONCLUSIONS: In an unselected population of patients with PHLF, LT is a very morbid procedure associated with high mortality but should be considered the only life-saving option in this group.

RESUMEN

BACKGROUND: There have been limited reports on immunosuppression strategies and outcomes in dual organ heart transplant populations, primarily from before the 2018 United Network for Organ Sharing (UNOS) heart allocation policy change. Recent data suggested that outcomes with heart-lung and heart-liver transplants remained comparable in the new allocation era, yet heart-kidney recipients have worse 1-year survival. METHODS: This single-center retrospective study evaluated adult heart-kidney, heart-liver, and heart-lung transplant recipients from September 2019 to May 2023. Immunosuppression regimen, infectious complications, and graft outcomes were collected for 12 months. RESULTS: A total of 36 patients (kidney n = 20, liver n = 9, and lung n = 7) were included in this study. Basiliximab was the most commonly employed induction strategy across the organ groups (12/20 in kidney, 4/9 in liver, and 7/7 in lung). All patients were on triple immunosuppression at 12 months posttransplant with prednisone wean achieved in one heart-liver recipient. Infection complications were frequently reported (95% kidney, 75% liver, 100% lung group). One patient went back to dialysis due to focal segmental glomerulosclerosis. One chronic lung allograft dysfunction was reported, but no other severe biopsy-proven rejection or retransplant was reported. The 1-year survival was 85% (17/20) in heart-kidney, 78% (7/9) in heart-liver, and 86% (6/7) in heart-lung recipients. CONCLUSION: This study summarized real-world immunosuppression strategies and outcomes in dual organ heart transplant recipients.

RESUMEN

To explore preoperative and operative risk factors for red blood cell (RBC) transfusion requirements during liver transplantation (LT) and up to 24 h afterwards. We evaluated the associations between risk factors and units of RBC transfused in 176 LT patients using a log-binomial regression model. Relative risk was adjusted for age, sex, and the model for end-stage liver disease score (MELD) (adjustment 1) and baseline hemoglobin concentration (adjustment 2). Forty-six patients (26.14%) did not receive transfusion. Grafts from cardiac-death donors were used in 32.61% and 31.54% of non-transfused and transfused patients, respectively. The transfused group required more reoperation for bleeding (P = 0.035), longer mechanical ventilation after LT (P < 0.001), and longer ICU length of stay (P < 0.001). MELD and hemoglobin concentrations determined RBC requirements. For each unit of increase in the MELD score, 2% more RBC units were transfused, and non-transfusion was 0.83-fold less likely. For each 10-g/L higher hemoglobin concentration at baseline, 16% less RBC transfused, and non-transfusion was 1.95-fold more likely. Ascites was associated with 26% more RBC transfusions. With an increase of 2 mm from the baseline in the A10FIBTEM measurement of maximum clot firmness, non-transfusion was 1.14-fold more likely. A 10-min longer cold ischemia time was associated with 1% more RBC units transfused, and the presence of post-reperfusion syndrome with 45% more RBC units. We conclude that preoperative correction of anemia should be included in LT. An intervention to prevent severe hypotension and fibrinolysis during graft reperfusion should be explored.Trial register: European Clinical Trials Database (EudraCT 2018-002,510-13) and ClinicalTrials.gov (NCT01539057).

RESUMEN

OBJECTIVES: Perioperative coagulation management in liver transplantation recipients is challenging. Viscoelastic testing with rotational thromboelastography (TEG) can help quantify hemostatic profiles. The current work aimed to investigate whether the etiology of end-stage liver disease, pretransplant disease severity, or pretransplant thrombotic or bleeding complications are associated with specific TEG patterns. DESIGN: Retrospective cohort study. SETTING: Single quaternary care hospital. PARTICIPANTS: A total of 1,078 adult liver transplant patients. INTERVENTIONS: The primary exposure was the etiology of end-stage liver disease classified as either intrinsic or nonintrinsic (eg, biliary obstruction or cardiovascular). Secondary exposures were patients' preoperative Model for End-Stage Liver Disease (MELD) score, Child-Pugh class, presence of major preoperative thrombotic complications, and major bleeding complications. MEASUREMENTS AND MAIN RESULTS: Patients with intrinsic liver disease (84%) showed higher odds of hypocoagulable (odds ratio [OR]: 3.70, 95% confidence interval [CI]: 1.94-7.07, p < 0.0001) and mixed TEG patterns (OR: 4.59, 95% CI: 2.07-10.16, p = 0.0002) compared with those with nonintrinsic disease. Increasing MELD scores correlated with higher odds of hypocoagulable (OR: 1.14, 95% CI: 1.08-1.19, p < 0.0001) and mixed TEG patterns (OR: 1.08, 95% CI: 1.03-1.14, p = 0.0036). Child-Pugh class C was associated with higher odds of hypocoagulable (OR: 8.55, 95% CI: 3.26-22.42, p < 0.0001) and mixed patterns (OR: 12.48, 95% CI: 3.89-40.03, p < 0.0001). Major preoperative thrombotic complications were not associated with specific TEG patterns, although an interaction with liver disease severity was observed. CONCLUSIONS: Liver transplantation candidates with intrinsic liver disease tend to exhibit hypocoagulable TEG patterns, while nonintrinsic disease is associated with hypercoagulability. Increasing end-stage liver disease severity, as evidenced by increasing MELD scores and higher Child-Pugh classification, was also associated with hypocoagulable TEG patterns.

RESUMEN

AIMS: This review explores the mechanisms, diagnostic approaches, and management strategies for COVID-19-induced liver injury, with a focus on its impact on patients with pre-existing liver conditions, liver cancer, and those undergoing liver transplantation. MATERIALS AND METHODS: A comprehensive literature review included studies on clinical manifestations of liver injury due to COVID-19. Key areas examined were direct viral effects, drug-induced liver injury, cytokine storms, and impacts on individuals with chronic liver diseases, liver transplants, and the role of vaccination. Data were collected from clinical trials, observational studies, case reports, and review literature. KEY FINDINGS: COVID-19 can cause a spectrum of liver injuries, from mild enzyme elevations to severe hepatic dysfunction. Injury mechanisms include direct viral invasion, immune response alterations, drug toxicity, and hypoxia-reperfusion injury. Patients with chronic liver conditions (such as alcohol-related liver disease, nonalcoholic fatty liver disease, cirrhosis, and hepatocellular carcinoma) face increased risks of severe outcomes. The pandemic has worsened pre-existing liver conditions, disrupted cancer treatments, and complicated liver transplantation. Vaccination remains crucial for reducing severe disease, particularly in chronic liver patients and transplant recipients. Telemedicine has been beneficial in managing patients and reducing cross-infection risks. SIGNIFICANCE: This review discusses the importance of improved diagnostic methods and management strategies for liver injury caused by COVID-19. It emphasizes the need for close monitoring and customized treatment for high-risk groups, advocating for future research to explore long-term effects, novel therapies, and evidence-based approaches to improve liver health during and after the pandemic.

RESUMEN

BACKGROUND: To review the impact of the operating microscope (OM) for reconstruction of the hepatic artery (HA) by comparing the outcomes with standard loupe reconstruction (SL) in pediatric liver transplantation (LT). METHODS: Studies comparing the application of OM and SL for the reconstruction of the HA in primary pediatric LT were included from a systematic search of MEDLINE, Cochrane Library and EMBASE from inception to June 2022. Re-transplantation, dual grafts and auxiliary transplants were excluded. Primary outcome was the rate of HA thrombosis (HAT). Secondary outcomes were graft loss and mortality. RESULTS: There were 1261 liver recipients from 9 included studies published until June 2022. There were 484 patients in the OM group and 777 patients in the SL group. HAT incidence with OM was significantly lower with OR = 0.18 (95% CI: 0.07-0.48). The 1-year graft survival was significantly better in the OM group with OR = 2.77 (95% CI: 1.13-6.80). 1-year overall mortality was also significantly lower with OM with OR = 0.39 (0.18-0.86). The use of OM did not significantly impact the incidence of HAT in the living donor liver transplant subgroup. Differences in time for hepatic HA reconstruction, total operating time and length of hospital stay did not reach statistical significance. CONCLUSION: The use of OM has reduced the risk of HAT, graft loss and mortality in pediatric liver transplantation. Adoption of microsurgical principles in general may have contributed to the improved outcomes with SL reconstruction of HA in pediatric LT.

RESUMEN

INTRODUCTION: We prospectively evaluated 3 cases regarding the usefulness of fully-covered self-expandable metal stents (FCSEMSs) for hepaticojejunostomy anastomotic stricture (HAS) after living donor liver transplantation (LDLT), which could not be resolved with conventional treatment using a plastic stent. CASE REPORT: All patients underwent LDLT with Roux-en-Y reconstruction; therefore, a short-type double-balloon enteroscope was used for the endoscopic procedures. HAS was observed on enteroscopic view of endoscopy in patients 1 and 2, and cholangiography revealed dilatation of the intrahepatic bile duct. The FCSEMS was successfully placed without the report of adverse events. The FCSEMS was removed after 16 weeks, and the HAS improved in both patients. In addition, stone clearance was also achieved in patient 2. On the other hand, FCSEMS was not placed in patient 3 because there was no indication of FCSEMS placement due to the multiple segmental biliary strictures (pruned-tree appearance on cholangiography). Subsequent deceased-donor liver transplantation confirmed recurrent primary sclerosing cholangitis. In this case, magnetic resonance cholangiopancreatography (MRCP) was not performed prior to cholangiography to rule out PSC recurrence. CONCLUSION: FCSEMS placement may be effective and safe for HAS after LDLT, which is not resolved with conventional treatment using a plastic stent. MRCP should be used to identify HAS prior to invasive cholangiography.
