Review
Neonatal hemochromatosis (NH) is an uncommon, severe disorder that results in fetal loss or neonatal death due to liver failure. NH is currently regarded as the phenotypic expression of gestational alloimmune liver disease (GALD). The diagnosis of NH-GALD is rarely prenatally established. In addition to providing a systematic review of the prenatal features that are identifiable using ultrasound (US) and MRI, we suggest a prenatal diagnosis algorithm for use in suspected NH during the first affected pregnancy. From a total of 586 database entries identified in PubMed, Google Scholar, and ResearchGate, we selected 18 studies published from 1993 to 2021 that reported maternal medical and obstetric history, prenatal ultrasound findings, and postpartum outcomes. We investigated the ultrasound and MRI features of these studies, along with the outcome due to this condition. A total of 74 cases were identified. The main reported prenatal US finding was fetal growth restriction (FGR) (33%), followed by oligohydramnios (13%) and hydrops fetalis (13%), with 13% cases described as uneventful. Other rare prenatal findings were fetal anemia, ascites, and abnormal fetal liver and spleen. Most pregnancies ended with fetal/perinatal death or therapeutic interruption of pregnancy. Favorable evolution with treatment (ensanguine transfusion and intravenous immunoglobulin (IVIG)) was reported for only 7% of fetuses. Using T2-weighted MRI, fetal extrahepatic siderosis confirmed prenatally in two cases and postnatally in 11 cases. IVIG treatment throughout subsequent pregnancies was found to significantly improve fetal prognosis. MRI should be indicated in selected cases of oligohydramnios, fetal hydrops, fetal hepatomegaly, ascites, or unexplained FGR or anemia after ruling out all other more frequently encountered conditions. MRI can be used to detect iron overload in the liver and extrahepatic siderosis.

Meta-Analysis Review
BACKGROUND & AIMS
Non-selective β blockers (NSBBs) may negatively influence renal function through decreasing heart rate and cardiac output. This study aimed to systematically investigate their association.
METHODS
PubMed, EMBASE, and Cochrane library databases were searched to identify all relevant studies evaluating the association of NSBBs with renal dysfunction in cirrhotic patients. Unadjusted and adjusted data were separately extracted. Odds ratios (ORs) and hazard ratios (HRs) were pooled. Subgroup meta-analyses were performed according to the proportions of ascites and Child-Pugh class B/C and the mean model for end-stage liver disease (MELD) score. Quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework.
RESULTS
Fourteen studies were finally included. Based on unadjusted data, NSBBs significantly increased the risk of developing renal dysfunction (OR = 1.49; = 0.03), and this association remained significant in subgroup analyses of studies where the proportions of ascites was >70% and Child-Pugh class B/C was 100%. Based on adjusted data with propensity score matching (adjusted OR = 0.61; = 0.08) and multivariable regression modelling (adjusted HR = 0.86; = 0.713), NSBBs did not increase the risk of developing renal dysfunction, and this association remained not significant in subgroup analyses of studies where the proportions of ascites was >70% and <70%, the proportion of Child-Pugh class B/C was <100%, and the mean MELD score was <15. The quality of evidence was very low for all meta-analyses.
CONCLUSIONS
NSBBs may not be associated with the development of renal dysfunction in liver cirrhosis. However, more evidence is required to clarify their association in specific populations.

Meta-Analysis Review
BACKGROUND
The goal of this systematic review and meta-analysis was analyzing published studies on the role of neutrophil to lymphocyte ratio (NLR) in infection and spatially spontaneous bacterial peritonitis (SBP) among cirrhotic patients.
METHODS
PubMed, Web of Science, and Scopus were searched until May 24, 2022. The Newcastle-Ottawa scale was used for quality assessment.
RESULTS
Of 14 studies included in our study, six studies were on infection with 2786 hospitalized cirrhotic patients, of whom 934 developed an infection. Other studies were on SBP with 1573 cirrhotic patients with ascites, of whom 557 developed SBP. The pooled results showed that there was no difference in NLR levels between hospitalized cirrhotic patients who developed infection compared to those who did not (random-effects model: SMD = 0.63, 95% CI = -0.01-1.27, =0.054). However, cirrhotic patients with ascites who developed SBP had elevated levels of NLR compared to those who did not (random-effects model: SMD = 1.05, 95% CI = 0.52-1.57, < 0.001). This difference remained significant in prospective studies (SMD = 0.94, 95% CI = 0.51-1.38, < 0.001) but not in retrospective studies (SMD = 1.37, 95% CI = -0.56-3.29,=0.165), in the subgroup analysis according to the study design. The pooled sensitivity of NLR was 92.07% (95% CI = 74.85%-97.84%) and the pooled specificity was 72.58% (95% CI = 57.72%-83.69%). The pooled positive likelihood ratio, negative likelihood ratio, DOR of NLR were 3.35(95%CI = 2.06-5.46), 0.10 (95%CI = 0.03-0.38), and 30.78 (95%CI = 7.01-135.04), respectively.
CONCLUSION
Our results support NLR to be a valid biomarker that can be readily integrated into clinical settings to help in the prevention and prediction of SBP among cirrhotic patients.

Meta-Analysis
Introduction and objectives It has been suggested that albumin administration could alter the natural history of cirrhosis, and also, that long-term treatment with albumin might be associated with improvement in survival, control of ascites, reduction in the incidence bacterial infections, renal dysfunction, hepatic encephalopathy (HE) and hyponatremia, as well as reduction in length of hospitalization in patients with cirrhosis and ascites. The objective of the present study is to evaluate the role of albumin in the management of HE. Materiales and methods:: This is a systematic review of randomized controlled trials that evaluated the use of albumin in adult patients with cirrhosis and HE. The search for eligible studies was performed in MEDLINE, EMBASE, and Cochrane CENTRAL databases until June 2020. The outcomes of interest were the complete reversal of HE and mortality. Meta-analysis was performed using the random effects model, through the Mantel-Haenszel method. Results: This systematic review was registered at the PROSPERO platform (CRD42020194181). The search strategy retrieved 1,118 articles. After reviewing titles and abstracts, 24 studies were considered potentially eligible, but 22 were excluded after full-text analysis. Finally, 2 studies were included. In the meta-analysis, albumin was associated to significant lower risks of persistent HE (risk ratio - RR = 0.60; 95% confidence interval - CI = 0.38-0.95, p = 0.03) and mortality (RR = 0.54; 95% CI = 0.33-0.90, p = 0.02). Conclusion: Albumin administration improves HE and reduces mortality in patients with cirrhosis and HE.

Meta-Analysis
BACKGROUND
Alcohol related liver disease (ARLD) is one of the major chronic liver diseases worldwide. This review aimed to describe the global prevalence, incidence, and outcomes of ARLD.
METHODS
Medline, Embase, The Cochrane Library, and China National Knowledge Infrastructure (CNKI) were searched from inception to May 31, 2022. The language was restricted to English or Chinese. According to the criteria, articles describing the basic characteristics of the population were selected. Two reviewers extracted the data independently.
RESULTS
A total of 372 studies were identified: 353 were used for prevalence analysis, 7 were used for incidence analysis, and 114 were used to for outcome analysis. The prevalence of ARLD worldwide was 4.8%. The prevalence in males was 2.9%, which was higher than female (0.5%). Among the ethnic groups, the percentage was highest in Caucasians (68.9%). Alcoholic liver cirrhosis comprised the highest proportion in the disease spectrum of ARLD at 32.9%. The prevalence of ascites in ARLD population was highest (25.1%). The ARLD population who drinking for > 20 years accounted for 54.8%, and the average daily alcohol intake was 146.6 g/d. About 59.5% of ARLD patients were current or former smokers, and 18.7% were complicated with hepatitis virus infection. The incidence was 0.208/1000 person-years. The overall mortality was 23.9%, and the liver-related mortality was 21.6%.
CONCLUSION
The global prevalence of ARLD was 4.8% and was affected by sex, region, drinking years, and other factors. Therefore, removing the factors causing a high disease prevalence is an urgent requisite.

BACKGROUND
Staging laparoscopy for gastric cancer is recommended to assess the tumor's locoregional extension and exclude peritoneal disease. As there is no consensus on optimizing the procedure's diagnostic accuracy, we aimed to systematically review the literature on operative techniques, followed by peritoneal lavage fluid assessment in gastric cancer patients. Specifically, we sought to indicate the most common characteristics of the procedure and cytological evaluation.
METHODS
This study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The protocol for this systematic review was registered on PROSPERO database (CRD: 42022306746). On September 2022, a search was carried out using Embase, Medline ALL, Cochrane Central Register of Controlled Trials, and Web of Science Core Collection.
RESULTS
The search identified 1632 studies on staging laparoscopy and 2190 studies on peritoneal fluid assessment. Some 212 studies were included. Open Hasson was the method of choice in accessing the peritoneal cavity in 65% of the studies, followed by establishing a pneumoperitoneum at 10-12 mmHg in 52% of reports. Most frequently, the patient was positioned supine (70%), while a 30° scope and three ports were used to assess the peritoneal cavity clockwise (72%, 77%, and 85%, respectively). Right and left upper abdomen quadrants were the predominant area of laparoscopic exploration (both 65%), followed by the primary tumor region (54%), liver and pelvis (both 30%), and small bowel and spleen (19% and 17%, respectively). Regions of peritoneal lavage and aspiration were limited to the pelvis (50%), followed by right and left upper abdomen quadrants (37.5% and 50%, respectively). No studies compared different methods of operative techniques or analysis of ascites/fluid.
CONCLUSIONS
This study indicates a high heterogeneity in the technique of staging laparoscopy and peritoneal fluid assessment in gastric cancer patients. Further research and initiatives to reach a consensus on the standardization of the procedure are warranted.

Meta-Analysis Review
BACKGROUND
Refractory ascites is a severe complication of liver cirrhosis and treatment options consist in large volume paracentesis, transjugular intrahepatic portosystemic shunt, alfapump®, peritoneovenous shunt and permanent indwelling peritoneal catheter.
AIM
Our aim was to assess the efficacy, mortality and complications of each treatment.
METHODS
We performed a systematic review using Pubmed and Embase. Frequencies were summarized with Comprehensive Meta-Analysis Software.
RESULTS
Seventy-seven studies were included. In patients with transjugular intrahepatic portosystemic shunt, 1-year mortality was 33% (95% CI 0.29-0.39, I=82.1; τ = 0.37; p<0.001) with lower mortality in newer studies (26% vs. 44%). At 6 months, mortality in patients with alfapump® was 24% (95% CI 0.16-0.33, I=0.00; τ = 0.00; p = 0.83), 31% developed acute kidney injury (95% CI 0.18-0.48, I=44.0; τ = 0.22; p = 0.15). Mortality at 12 months was 44% (95% CI 32%-58%, I=76.7, τ = 0.44, p<0.001) in peritoneovenous shunts and 45% (95% CI 38%-53%, I=61.4, τ = 0.18, p = 0.003) in large volume paracentesis, respectively. Overall mortality in patients with permanent indwelling catheters was 66% (95% CI 33%-89%, I=82.5, τ = 1.57, p = 0.001).
DISCUSSION
Mortality in patients with transjugular intrahepatic portosystemic shunt was lower in newer studies, probably due to a better patient selection. Acute kidney injury was frequent in patients with alfapump®. Permanent indwelling catheters seemed to be a good option in a palliative setting.

Abdominal Radiology (New York) Mar 2021This scoping review evaluated the currently available data related to abdominal imaging in the SARS-CoV-2 infection.
PURPOSE
This scoping review evaluated the currently available data related to abdominal imaging in the SARS-CoV-2 infection.
METHOD
A systematic review of MEDLINE, EMBASE, SCOPUS, and Web of Science was performed from inception to July 15, 2020 using PRISMA-ScR guidelines. The review included case reports and series discussing radiologic manifestations of SARS-CoV-2 infection in abdominal imaging studies. Studies published from inception to March 31, 2020, were independently screened and reviewed by one author, and another author reviewed studies published after March 31 to July 15, 2020. Study screening and full-text review for publications before March 31, 2020, was performed by one author, and another author for publications after March 31 to July 15, 2020.
RESULTS
Thirty-six studies were included in qualitative synthesis. The prevalence of gastrointestinal symptoms is roughly 18% and includes loss of appetite, nausea, vomiting, diarrhea, and abdominal pain. Sixteen percent of COVID-19 cases may only present with gastrointestinal symptoms. Many patients presenting this way demonstrate evidence of COVID-19 incidentally through abdominal CT imaging at the lung bases. Studies published to date have also reported abdominal imaging findings including small and large bowel wall thickening, fluid-filled colon, pneumatosis intestinalis, pneumoperitoneum, intussusception, and ascites.
CONCLUSION
Gastrointestinal manifestations and imaging manifestations of SARS-CoV-2 infection are increasingly reported and warrant specific attention during abdominal imaging.

Meta-Analysis Review
BACKGROUND
Transjugular liver biopsy (TJLB) procedurally samples liver tissue through the internal jugular vein. It is indicated in the presence of coagulopathies and/or ascites.
AIMS
This meta-analysis aimed to assess the safety and efficacy of TJLB in children.
METHODS
A literature search of several databases was conducted from inception to August 2022. Eligible studies reported pediatric patients (< 18 years old) who underwent TJLB. The pooled proportion was analyzed using a random-effects model. This review was registered in PROSPERO (CRD42022354421).
RESULTS
From 921 initial studies screened, eight met the eligibility criteria, with a total of 361 pediatric patients who underwent 374 TJLBs. All eight studies reported pooled rates of technical success at 99.1% (95% CI 0.982, 1.001; I = 0%) and histological adequacy of sampling at 97.5% (95% CI 0.954, 0.995; I = 27.66%). A total of 49 complications were reported across six studies, the most common being bleeding from the entry site (38.78%), fevers for less than 24 h (12.24%), red blood cells transfusion requirement (10.2%), supraventricular tachycardia (8.16%), and pain requiring analgesia (8.16%).
CONCLUSION
Pediatric TJLB demonstrates high rates of technical success and adequate liver core biopsy samples, with a low rate of complications. These results suggest that TJLB is an effective method for diagnostic yield and postprocedural outcomes, especially in patients with preexisting coagulopathies and ascites where percutaneous liver biopsy is contraindicated. Additional studies evaluating larger groups of pediatric patients may provide further support for the use of TJLB in this population.

Review
BACKGROUND
Chyle leakage/ascites after surgical resection of neuroblastic tumors may delay the start of chemotherapy and worsen prognosis. Previous studies have reported a highly variable incidence and risk factors remain largely unknown. This study aims to analyze the true incidence of chyle leaks and ascites and seeks to identify risk factors and optimal treatment strategies.
METHODS
Medline/Embase databases were searched according to PRISMA guidelines. Literature reviews, case reports, and non-English papers were excluded. Data were extracted independently following paper selection by 2 authors.
RESULTS
The final analysis yielded 15 studies with N = 1468 patients. Chylous ascites was recorded postoperatively in 171 patients (12%). Most patients experiencing chyle leaks were successfully treated conservatively with drainage, bowel rest, parenteral nutrition and octreotide with variable combinations of these treatment options. 7/171 (4%) patients required operative exploration to control troublesome persistent chyle leaks. In risk factor analysis, higher tumor stage was significantly associated with the risk of chyle leak (P < 0.0001) whereas no correlation was observed with adrenal vs non-adrenal tumor location, INRG risk groups and tumor laterality.
CONCLUSION
Chyle leakage after surgery for neuroblastic tumors is a common morbid complication occurring in some 12% of patients. Higher INSS tumor stage portends greater risk(s). Conservative therapy strategies appear successful in the majority of cases. To avert this complication meticulous mesenteric lymphatic ligation is recommended especially for those patients with higher tumor stage(s) requiring extensive radical surgery including retroperitoneal lymph node resection.
