Is Being In The Geriatric Age Group An Additional Risk Factor Or Contraindication For Living Donor Liver Transplantation?

Introduction: While advanced age was once a contraindication for liver transplantation, it is now routinely performed for individuals over (≥) 65. This study aimed to analyze preoperative findings, preoperative findings, perioperative graft-related and surgical factors, and postoperative complications in geriatric recipients (≥65 years) to assess the feasibility and outcomes of living-donor liver transplantation in this age group. Materials and Method: Data regarding sex, model for end-stage liver disease score, Child score, body mass index, blood type, graft type (right or left lobe), ascites, esophageal variceal hemorrhage, hepatic encephalopathy, spontaneous bacterial peritonitis, preoperative INR, platelet, sodium, albumin, total bilirubin and creatinine, diabetes, hypertension, coronary artery disease, anhepatic phase, cold ischemia time, operation time, blood products transfusion rates, graft-to-recipient weight ratio, intensive care unit and hospital stay, biliary complications, hepatic vein thrombosis, portal vein thrombosis, postoperative hemorrhage, sepsis, and primary graft dysfunction were analyzed statistically in geriatric patients. Results: The use of the right lobe was significantly higher in the ≥65 age group (p=0.036). Additionally, body mass index (p=0.039) and creatinine (p=0.018) were statistically higher in the group. Conclusion: Living-donor liver transplantation can be safely performed in patients aged ≥65 years. Keywords: Liver; Survival; Transplantation.

Evaluation of Noninvasive Tools for Predicting Esophageal Varices in Patients With Cirrhosis at Tygerberg Hospital, Cape Town.

Background: In patients with cirrhosis, esophageal variceal hemorrhage (EVH) is a devastating consequence of portal hypertension (PH). Upper endoscopy is considered the gold standard for the detection and diagnosis of esophageal varices (EVs), despite being invasive and costly. This study was aimed at identifying and evaluating the diagnostic accuracy of noninvasive tools in predicting EVs in patients with compensated cirrhosis. Methods: This cross-sectional study included 50 patients with compensated cirrhosis at the Tygerberg Hospital Gastroenterology Clinic in Cape Town between November 2022 and May 2023. We collected clinical, anthropometric, and laboratory data from patients' physical and electronic charts. All patients underwent an abdominal ultrasound, vibration-controlled transient elastography (VCTE) to assess liver and splenic stiffness, and upper endoscopy. In this comparative study, we evaluated the diagnostic accuracy of different noninvasive tools in detecting EVs in patients with compensated cirrhosis. Results: Of the 50 patients included in the study, 30 (60%) were female and 20 (40%) were male. The patients' age ranged from 18 to 83, with a mean age of 46.6 years. Cirrhosis was mainly due to alcohol use (n = 11, 22%), hepatitis B virus (HBV) infection (n = 11, 22%), and autoimmune hepatitis (n = 10, 20%). The patients included in the study were divided into two subgroups: with (n = 34, 68%) or without (n = 16, 32%) EVs. Statistically significant differences were detected between groups in platelet count (PC), liver stiffness measurement (LSM), spleen stiffness measurement (SSM), portal vein diameter (PVD), bipolar spleen diameter (SBD), aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis-4 index (FIB-4), platelet/bipolar spleen diameter ratio (PSR), liver stiffness-spleen size-platelet ratio (LSPS), liver stiffness-spleen stiffness-platelet ratio score (LS3PS), and spleen stiffness-spleen size-platelet ratio score (SSPS) (p < 0.001). The highest diagnostic precision was observed with SSM (96%), SSPS (96%), LS3PS (94%), LSPS (94%), PSR (94%), and PC (92%). SBD (88%), LSM (86%), APRI (82%), and FIB-4 (82%) had the lowest diagnostic accuracy. Conclusion: SSM and SSPS have the highest diagnostic accuracy for predicting the presence of EVs in patients with compensated cirrhosis. LSPS, LS3PS, and PSR come second at 94%. We recommend SSM and SSPS in institutions with transient elastography equipped with the software necessary to measure splenic stiffness. We introduce and propose LS3PS as a novel composite score for predicting the presence of EVs in patients with compensated cirrhosis. Large-sample-size studies are needed to validate these prediction scores and to allow direct comparison with Baveno VII. These prediction tools can help clinicians avoid unnecessary endoscopic procedures in patients with compensated cirrhosis, especially in developing countries with limited resources such as South Africa.

Sequential endoscopic treatment for esophageal and gastric variceal bleeding significantly reduces patient mortality and rebleeding rates

Background: Esophageal-gastric variceal bleeding (EGVB) is a serious complication in patients with liver cirrhosis, characterized by high mortality and rebleeding rates. The effect of sequential endoscopic therapy on patient mortality and rebleeding rates remains unclear. Objectives: This study aimed to evaluate the effects of sequential endoscopic therapy on mortality and rebleeding rates in patients with EGVB. Design: In this single-center retrospective study, 373 hospitalized cases of EGVB caused by liver cirrhosis, collected between November 2019 and November 2023, were divided into four groups according to different treatment methods: a sequential endoscopy group, emergency endoscopy group, emergency endoscopy plus transjugular intrahepatic portosystemic shunt (TIPS) group and control group. Methods: Mortality and rebleeding rates were compared among the four groups using statistical analyses. Results: The mortality and rebleeding rates of the sequential endoscopy group (3.7% and 19%, respectively) were significantly lower than those of the emergency endoscopy (22% and 36%, respectively), emergency endoscopy plus TIPS (33% and 28%, respectively), and control groups (33% and 51%, respectively) ( p = 0.013 and p = 0.013, respectively). Conclusion: Sequential endoscopic therapy may significantly reduce the mortality and rebleeding rates of patients with EGVB compared to other conventional treatment strategies. The findings of the study could help develop approaches benefiting EGVB treatment.

Characteristics and Related Factors of Bacterial Infection Among Patients With Cirrhosis.

Infection causes cirrhosis to decompensate, affecting liver function and resulting in several complications, including esophageal variceal hemorrhage, hepatic encephalopathy, and hepatorenal syndrome. Objective: This study aimed to identify the prevalence, essential features, and related factors of bacterial infection among patients with cirrhosis in Vietnam. This retrospective study included 317 patients diagnosed with cirrhosis, who were divided into two groups: group 1 including 125 patients with bacterial infection and group 2 including 192 patients without bacterial infection. Infection was diagnosed on the basis of its localization. Spontaneous bacterial peritonitis (SBP; 31.2%) and pneumonia (28.8%) were the most common infections identified. The procalcitonin (PCT) level had a strong diagnostic value with an area under the curve value of 0.868. The most common type of gram-negative bacteria was Escherichia coli, while the gram-positive bacteria seen were Staphylococcus, Enterococcus, and Streptococcus among the patients with infection. In the logistic regression analysis, Child-Pugh class B and C (p<0.001, OR=4.14, CI=1.90-9.03; OR=4.76, CI=2.03-11.16, respectively) and the presence of acute kidney injury (p=0.009, OR=2.57, CI=1.27-5.22) and gastrointestinal hemorrhage (p=0.035, OR=0.39, CI=0.16-0.94) significantly differed between the groups. The most prevalent type of bacterial infection in patients with cirrhosis is SBP, with gram-negative bacteria being the most common cause. The PCT level is useful in identifying infection in patients with cirrhosis. Decompensated cirrhosis is linked to a higher risk of infection.

Potentials of Endoscopic Combined Treatment of Esophageal Variceal Bleeding in Patients with Liver Cirrhosis

Background. Treatment of variceal esophageal-gastric bleeding in patients with portal hypertension is an acute challenge in urgent surgery.The aim of study was to develop a technique and evaluate the immediate and long-term effectiveness of endoscopic ligation (EL) with the use of cytoprotective treatment.Materials and methods. The study included 106 patients who were treated at the City Clinical Emergency Hospital No. 1, Voronezh, Russia. The main group consisted of 54 patients who were treated using a developed technique of combined endoscopic ligation of esophageal varices combined with the polymer alginate hemostatic sorbent (PAHS) application on ligated nodes and post-ligature defects. The comparison group consisted of 52 patients who underwent endoscopic ligation without PAHS application.Results. In the main group, total hemostasis was achieved in 52 of 54 (96.3%) patients, p = 0.027; recurrent bleeding was observed in 2-3 days after combined ligation in two (3.7%) patients. No operations were performed; two (3.7%) patients died in this group. In the comparison group, total hemostasis was achieved in 43 of 52 (82.6%) patients, p=0.027. Recurrent bleeding was observed in nine (17.3%) patients. In the comparison group, one (1.9%) patient with massive bleeding was operated on, and seven (13.5%) patients died.Conclusion. Endoscopic ligation combined with cytoprotective treatment using a polymer alginate hemostatic sorbent increases the effectiveness of local hemostasis and reduces the rate of recurrent hemorrhage from 17.3% to 3.7%, p = 0.027. Insufflation of PAHS onto ligature nodes and defects helps relieve pain, accelerates the processes of postligature defect epitheliation from 7.7% to 94.4%, p=0.0001; it also prolongates the remission of the underlying disease.

The role of computed tomography for the prediction of esophageal variceal bleeding: Current status and future perspectives.

Esophageal variceal bleeding (EVB) is one of the most common and severe complications related to portal hypertension (PH). Despite marked advances in its management during the last three decades, EVB is still associated with significant morbidity and mortality. The risk of first EVB is related to the severity of both PH and liver disease, and to the size and endoscopic appearance of esophageal varices. Indeed, hepatic venous pressure gradient (HVPG) and esophagogastroduodenoscopy (EGD) are currently recognized as the "gold standard" and the diagnostic reference standard for the prediction of EVB, respectively. However, HVPG is an invasive, expensive, and technically complex procedure, not widely available in clinical practice, whereas EGD is mainly limited by its invasive nature. In this scenario, computed tomography (CT) has been recently proposed as a promising modality for the non-invasive prediction of EVB. Although CT is only a diagnostic modality, thus being not capable of supplanting EGD or HVPG in providing therapeutic and physiological data, it could potentially assist liver disease scores, HVPG, and EGD in a more effective prediction of EVB. However, to date, evidence concerning the role of CT in this setting is still lacking. Our review aimed to summarize and discuss the current evidence concerning the role of CT in predicting the risk of EVB.

Assessing the Predictive Factors for Bleeding in Esophageal Variceal Disease: A Systematic Review.

Esophageal varices, dilated submucosal distal esophageal veins, are a common source of upper gastrointestinal bleeding in patients with portal hypertension. This review aims to comprehensively assess predictive factors for both the first occurrence and subsequent risk of esophageal variceal bleeding. A systematic search was conducted in PubMed/MEDLINE (Medical Literature Analysis and Retrieval System Online) and Cochrane databases. A total of 33 studies were selected using rigorous inclusion and exclusion criteria. The risk of bias was assessed using the Newcastle-Ottawa Scale. Several predictive factors were identified for esophageal variceal bleeding, including the Child-Pugh score, Fibrosis Index, specific endoscopic findings, ultrasound parameters, portal vein diameter, presence and size of collaterals, CT scan findings, ascites, platelet counts, coagulation parameters, albumin levels, Von Willebrand Factor, bilirubin levels, diabetes mellitus, and the use of b-blocking agents in primary prophylaxis. The findings of this systematic review shed light on multiple potential predictive factors for esophageal variceal bleeding. Endoscopic findings were found to be reliable predictors. Additionally, ultrasound parameters showed associations with bleeding risk. This systematic review identifies multiple potential predictive factors for esophageal variceal bleeding in patients with portal hypertension. While certain factors exhibit strong predictive capabilities, further research is needed to refine and validate these findings, considering potential limitations and biases. This study serves as a critical resource for bridging knowledge gaps in this field.

Comparison of the management of gastric variceal bleeding techniques.

Managing gastric variceal (GV) hemorrhage is more complicated than managing esophageal variceal (EV) bleeding, resulting in significantly higher morbidity and mortality. We aim to compare the outcomes of endoscopic variceal ligation (EVL), transhepatic intrahepatic portosystemic shunt (TIPS), and balloon-occluded retrograde transvenous obliteration (BRTO) in the management of GV bleeding. We utilized the National Inpatient Sample (NIS) database from January 2016 to December 2019 to include adult patients with GV hemorrhage. Our study identified 7160 hospitalizations with a primary diagnosis of GV hemorrhage who underwent the interventions of interest. EVL was performed in 69.83%, TIPS in 8.72%, and BRTO in 4.88%. Patients with liver cirrhosis had a higher frequency of undergoing BRTO (68.6%), followed by TIPS (64.0%) and esophagogastroduodenoscopy (EGD) + TIPS (63.7%) (P < 0.001). Patients with cirrhosis secondary to alcoholism had a higher prevalence of TIPS (62.4%), followed by EGD + TIPS (69.4%) and BRTO (52.9%) (P < 0.001). Overall, the inpatient mortality was 6.5%. Overall inpatient mortality was highest in the TIPS cohort (8.8%), followed by BRTO (7.1%), EGD + TIPS (6.5%), EVL (6.2%), and EGD + BRTO (2.8%) (P < 0.001); However, the Kaplan-Meier graph showed endoscopy with BRTO had the most favorable 30-day survival, trailed by TIPS alone and BRTO alone. EVL remains a prominent therapeutic strategy. Remarkably, the combination of endoscopy with BRTO shows promising 30-day survival outcomes. Considering these observations, although EVL holds its primacy, it is essential to further explore the potential benefits of combined therapies in larger studies to ascertain the best treatment strategies.

Abstract 14822: Portopulmonary Hypertension Unveiled: Effects of Transjugular Intrahepatic Portopulmonary Shunt Placement

Introduction: Transjugular intrahepatic portosystemic shunts (TIPS) treat portal hypertension by connecting the portal vein to the hepatic vein in the liver. The resultant shunting of portal venous flow to the systemic circulation helps reduce the portosystemic gradient and is used to treat complications of portal hypertension. Right heart failure and the development of pulmonary hypertension after TIPS are known complications; however, portopulmonary hypertension (POPH) is rare. Description of Case: A 61-year-old male presents to the clinic for six months of exertional dyspnea, weight gain, and lower extremity edema. He has a history of coronary artery disease and nonalcoholic steatohepatitis cirrhosis, with TIPS placement four years prior for esophageal variceal bleeding. An echocardiogram revealed right ventricular (RV) dilatation with moderately reduced function, a flattened left ventricular septum, and an estimated pulmonary artery systolic pressure of 91 mmHg. An echocardiogram and right heart catheterization (RHC) performed before his TIPS showed normal RV function and pulmonary artery pressures (PAP). Decision Making: The patient was promptly started on furosemide and spironolactone, and after adequate diuresis, a repeat RHC was obtained, which showed significantly elevated PAP, and normal left-sided filling pressures and cardiac output. Other causes of pulmonary hypertension were ruled out, and the patient was started on tadalafil monotherapy for severe POPH, with significant improvement in his PAP (Table 1). Conclusion: POPH after TIPS is a rare complication that should be suspected in patients presenting with signs of right-sided volume overload. The mechanism by which TIPS leads to POPH is not entirely understood. The degree of RV dysfunction correlates with mortality, and prompt treatment is warranted.

Rifaximin Alfa and Liver Diseases: More Than a Treatment for Encephalopathy, a Disease Modifier.

RFX, a rifamycin-based antibacterial agent obtained by the culture of the actinomycete Streptomyces mediterranei, has a broad antibacterial spectrum covering gram- positive, gram-negative, aerobic, and anaerobic bacteria. RFX is an antibiotic that elicits its effect by inhibiting bacterial RNA synthesis. When administered orally, its intestinal absorption is extremely low (<0.4%), restricting antibacterial activity mainly in the intestinal tract, with few systemic side effects. RFX has been recommended by the American Association for the Study of Liver Diseases and the European Association for the Study of the Liver guidelines for the treatment of HE. RFX may contribute to restore hepatic function and to decrease the development of liver fibrosis. Its efficacy has been shown in patients with previous hepatic encephalopathy and several complications, such as infections, including spontaneous bacterial peritonitis, ascites and oesophageal variceal bleeding. Thus, RFX has an outstanding role in the therapeutic arsenal in hepatic cirrhosis, under the concept of disease modifier.

Deep learning to predict esophageal variceal bleeding based on endoscopic images.

Esophageal varix (EV) bleeding is a particularly serious complications of cirrhosis. Prediction of EV bleeding requires extensive endoscopy experience; it remains unreliable and inefficient. This retrospective cohort study evaluated the feasibility of using deep learning (DL) to predict the 12-month risk of EV bleeding based on endoscopic images. Six DL models were trained to perform binary classification of endoscopic images of EV bleeding. The models were subsequently validated using an external test dataset, then compared with classifications performed by two endoscopists. In the validation dataset, EfficientNet had the highest accuracy (0.910), followed by ConvMixer (0.898) and Xception (0.875). In the test dataset, EfficientNet maintained the highest accuracy (0.893), which was better than the endoscopists (0.800 and 0.763). Notably, one endoscopist displayed higher recall (0.905), compared with EfficientNet (0.870). When their predictions were assisted by artificial intelligence, the accuracies of the two endoscopists increased by 17.3% and 19.0%. Moreover, statistical agreement among the models was dependent on model architecture. This study demonstrated the feasibility of using DL to predict the 12-month risk of EV bleeding based on endoscopic images. The findings suggest that artificial intelligence-aided diagnosis will be a useful addition to cirrhosis management.

Correlation between Portal Vein Diameter and Esophageal Varices Grades in Chronic Liver Disease Patients using Ultrasonography and Endoscopy as a Diagnostic Tool

Background: Chronic liver disease accounts for 2.2% of deaths and 1.5% of disability-adjusted life years. Variceal bleeding is one of the preventable caused of death in chronic liver disease. About 30-40% of patients with compensated cirrhosis and 85% of those with decompensated cirrhosis are found to possess EV on screening endoscopy.Objective: To determine the correlation between Portal Vein Diameter (PVD) on ultrasound examination and grades of Esophageal Varices (EV) on endoscopy in patients with Chronic liver disease (CLD). Material and Methods: This was a cross-sectional, correlational study, carried out in the Department of Diagnostic Radiology in collaboration with the Department of Gastroenterology, at Lady Reading Hospital Peshawar, Pakistan. A total of sixty patients were sampled via consecutive random sampling from Jan 2022 to Sept 2022. The criteria used for dilated portal vein was = 13mm and = 13 cm for splenomegaly. Results: Out of total 60 patients with CLD, PVD ranged from 10 to 18mm, mean PVD being 14.1mm ±1.4. The splenic sizes ranged from 10 to 23 cm, with the mean splenic cranio-caudal dimension being 14.9 cm ± 2.1. The highest association is between the large EV and PVD &gt; 15 mm i.e., 52% of total large EVs. The differences between PVD to EV groups were statistically significant as determined by one-way ANOVA (F (2,57) =8.281, p= 0.001) and correlation was also statistically significant on Pearson's Correlation test (rs)[60] = 0.490, p &lt; 0.001.Conclusion: As there is a significant positive correlation between PVD and grades of EV in CLD patients. The PVD on ultrasound should be utilized where an endoscopic facility is not available, or is overburdened, to prevent life threatening esophageal variceal bleed.

Diabetes mellitus and the progression of non-alcoholic fatty liver disease to decompensated cirrhosis: a retrospective cohort study.

To determine the incidence of decompensated cirrhosis and associated risk factors in people hospitalised with non-alcoholic fatty liver disease (NAFLD) or non-alcoholic steatohepatitis (NASH) with or without cirrhosis. Retrospective cohort study; analysis of linked Queensland Hospital Admitted Patient Data Collection, Queensland Registry of Births, Deaths and Marriages, and Queensland Cancer Register data. Queensland residents aged 20 years or older admitted to Queensland hospitals with NAFLD/NASH during 1 July 2009 - 31 December 2018. Progression to decompensated cirrhosis (ascites, hepatic encephalopathy, or oesophageal variceal bleeding). We included data for 8006 patients in our analysis (10 082 admissions), including 4632 women (58%) and 2514 people with diabetes mellitus (31%); median follow-up time was 4.6 years (interquartile range, 2.7-7.2 years). Three hundred and fifty-one people (4.4%) experienced decompensated cirrhosis during the follow-up period. Of the 6900 people without cirrhosis, 4.5% (95% confidence interval [CI], 3.6-5.7%) experienced decompensated cirrhosis within ten years (mean, 0.5% per year; 95% CI, 0.4-0.6% per year); risk of progression was greater for people aged 70 years or older (v 20-39 years: adjusted hazard ratio [aHR], 4.7; 95% CI, 2.0-11.0) and those who had extrahepatic cancers (aHR, 5.0; 95% CI, 3.0-8.2), history of major cardiovascular events (aHR, 1.9; 95% CI, 1.2-3.1), or diabetes mellitus (aHR, 2.8; 95% CI, 2.0-3.9). Of the 1106 people with cirrhosis, 32.4% (95% CI, 27.2-38.3%) experienced decompensated cirrhosis within ten years (mean, 5.5% per year; 95% CI, 4.8-6.3% per year); risk of progression was greater for those with portal hypertension (aHR, 1.8; 95% CI, 1.3-2.7), extrahepatic cancer (aHR, 1.8; 95% CI, 1.1-2.9), or diabetes mellitus (aHR, 1.5; 95% CI, 1.1-2.0). Compared with people who had neither cirrhosis nor diabetes mellitus, the risk of decompensation was greater for people with cirrhosis (aHR, 10.7; 95% CI, 7.6-15.0) or cirrhosis and diabetes mellitus (aHR, 14.4; 95% CI, 10.1-20.6). Given the greater risk of progression to cirrhosis decompensation in people with diabetes mellitus, a disorder common in people with NAFLD/NASH, identifying advanced fibrosis and providing appropriate treatment for averting disease progression is vital.

Role of the phase angle in the prognosis of the cirrhotic patient: 15 years of follow-up.

In 2019, cirrhosis accounted for 2.4% of global deaths. The projection for 2030 is an increase in this index. In recent years, hospitalization costs have escalated by 36% for compensated cirrhosis and 24% for decompensated cirrhosis. Therefore, it is necessary to identify a tool capable of predicting the mortality of these patients according to their clinical condition and consequently extending their survival time. Different studies have shown that the phase angle (PA) can be a feasible method in clinical practice, with the potential to guide assertive patient management in the therapeutic of chronic liver disease. To evaluate the prognostic role of PA in cirrhotic patients over a 15-year follow-up period. Retrospective cohort study with 129 cirrhotic patients of both sexes over 18 years old. Diagnosis of cirrhosis by liver biopsy. The first year of data collection was 2007, and data regarding outcomes was collected in 2023. Data were gathered from medical records, such as esophageal varices (EV), EV bleeding, ascites, spontaneous bacterial peritonitis (SBP), encephalopathy, laboratory findings and PA. The cut-off value for the PA was 5.4°, a value described in 2012 by Fernandes et al for 129 patients evaluated in this study and the cut-off points for the Brazilian population presented in percentiles (P), as described by Mattiello et al. The mortality was assessed using the PA percentile through Kaplan-Meier curves and multivariate binary logistic regression models. Patients were divided into two groups according to the PA 5.4th (PA > 5.4°, n = 40; PA ≤ 5.4°, n = 89) PA percentile (< P50, n = 56; ≥ P50 n = 73). The percentile classification was more accurate in identifying long-term deaths than the 5.4º PA. Patients with < P50 had a higher number of relevant complications such as ascites, SBP, liver encephalopathy and HCC. PA is strongly correlated with serum albumin (P < 0.001), International Normalized Ratio (P = 0.01), total bilirubin (P = 0.02) and direct bilirubin (P = 0.003). PA is correlated with survival time (P < 0.001) and length of stay (P = 0.02). Logistic regression analysis shows that an increase of 1° in PA enlarges the cirrhotic patient's chance of survival by 17.7%. PA is a good predictor of morbidity and mortality for cirrhotic patients. The PA by percentile showed greater sensitivity in predicting mortality compared to the cut-off point of 5.4º.

Prediction of Severe Esophageal Varices in Patients With Cirrhosis Based on Levitt's CO Breath Test: A Proof of Concept Study.

This study investigated the feasibility of using erythrocyte (RBC) lifespan determined by Levitt's CO breath test (LCOBT) to predict esophageal varices needing treatment (VNT) in patients with cirrhosis. Esophageal varix bleeding is a common fatal complication of cirrhosis and portal hypertension. The gold standard for identifying VNT is esophagogastroduodenoscopy (EGD), an invasive procedure with low patient compliance. VNT screening based on Baveno VI criteria has mediocre specificity. RBC lifespan was determined by LCOBT in 53 cirrhotic patients (13 without varices, 11 mild/moderate varices, and 29 severe varices). Correlation of varix severity with RBC lifespan and other variables was analyzed. Rates of shortened RBC lifespan and thrombocytopenia (Baveno VI criteria) were compared. RBC lifespan correlated inversely with severity of varices (r=-0.793, P<0.001). Mean RBC lifespans were 129±31, 96±21, and 59±21 days for Nonvarix, Mild/Moderate, and Severe groups. Shortened RBC lifespan (<75d) was observed in 79.3% (23/29) of patients with severe varices, a frequency similar or identical to thrombocytopenia rates [original Baveno VI criteria, 86.2% (25/29), P=0.487; expanded criteria, 79.3% (23/29), P>0.999]. Among 24 patients without severe varices, shortened RBC lifespan was observed in 1 patient whereas thrombocytopenia was detected in 13 and 8 patients based on the original (P<0.001) and expanded criteria (P=0.010), respectively. RBC lifespan correlates inversely with varix severity in patients with cirrhosis. LCOBT may enable specific screening for VNT.

Living Donor-Initiated Domino Split-Liver Transplantation in Pediatric Setup: A Case Report With Literature Review

In patients undergoing liver transplantation for metabolic diseases, removing the patient's liver for transplantation to another recipient is called "domino liver transplantation." The extracted liver can be divided and transplanted into 2 recipients, which is called domino split-liver transplantation in the literature. However, in our study, the domino liver was obtained from a pediatric patient. A patient with maple syrup urine disease (MSUD) underwent a living donor liver transplant, and the explanted liver was divided in situ into right and left lobes and transplanted to 2 separate patients. Demographic data, surgical techniques, postoperative period, and patient follow-ups were evaluated. The father's left lobe liver graft was transplanted into a 12-year-old boy with MSUD. The removed liver was divided in situ into right and left lobes. The left lobe was transplanted to a 14-year-old male patient, whereas the right lobe was transplanted to a 67-year-old male patient. The donor and the first recipient were discharged on postoperative days 5 and 22. The second pediatric patient who underwent domino split-left lobe transplantation was discharged on postoperative day 23. The adult patient who underwent domino split-right lobe transplantation died on postoperative day 12 owing to massive esophageal variceal bleeding. Patients who underwent liver transplantation due to MSUD are among the best donor choices for domino liver transplantation. If the extracted liver has a sufficient volume and anatomic features for a split, it can be used in "selected cases."
