Review
Ectopic varices account for 5% of variceal bleedings and occur outside the gastro-esophageal region. This review evaluates the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) for ectopic variceal management. A comprehensive search through PubMed, Scopus, Web of Science, and Embase was conducted until January 16, 2023, using relevant keywords. Case reports and case series with fewer than 10 patients on TIPS for ectopic variceal management were included. The quality assessment followed the Joanna Briggs Institute checklist for case reports. This systematic review evaluated 43 studies involving 50 patients with ectopic varices undergoing TIPS. Patients had a mean age of 54.3 years, half were female, and two were pregnant. Alcoholic liver disease (48%) and hepatitis C infection (26%) were common causes of portal hypertension. Ascites and splenomegaly were reported in 32% and 28% of the patients, respectively. Rectal, oral, and stomal variceal bleeding accounted for 62%, 16%, and 22% of the patients, respectively. Ectopic varices were mainly located in the duodenum (28%) and rectum (26%) regions. Complications affected 42% of the patients, re-bleeding in eleven and hepatic encephalopathy in seven. The follow-up lasted 12 months on average, and finally, 5 received a liver transplant. Mortality post-TIPS was 18%. Despite complications and a notable mortality rate, favorable outcomes were observed in almost half of the patients with ectopic variceal bleeding managed with TIPS. Further research is warranted to refine strategies and improve patient outcomes.

INTRODUCTION
Diagnostic paracentesis is recommended for patients with cirrhosis admitted to the hospital, but adherence is suboptimal with unclear impact on clinical outcomes. This meta-analysis aimed to assess the outcomes of early vs. delayed diagnostic paracentesis among hospitalized patients with cirrhosis and ascites.
METHODS
We searched multiple databases for studies comparing early vs. delayed diagnostic paracentesis among hospitalized patients with cirrhosis and ascites. The pooled odds ratio (OR) and mean difference (MD) with confidence intervals (CI) for proportional and continuous variables were calculated using the random-effects model. Early diagnostic paracentesis was defined as receiving diagnostic paracentesis within 12-24 hours of admission. The primary outcome was in-hospital mortality. Secondary outcomes were length-of-hospital-stay (LOS), acute kidney injury (AKI), and 30-day readmission.
RESULTS
Seven studies (n=78,744) (n=45,533 early vs. n=33,211 delayed diagnostic paracentesis) were included. Early diagnostic paracentesis was associated with lower in-hospital mortality (OR 0.61, 95% CI 0.46-0.82, P=0.001), LOS (MD -4.85 days; 95% CI -6.45, -3.20; P<0.001), and AKI (OR 0.62, 95% CI 0.42-0.92, P=0.02) compared to delayed diagnostic paracentesis, with similar 30-day readmission (OR 1.11, 95% CI 0.52-2.39, P=0.79). Subgroup analysis revealed consistent results for in-hospital mortality whether early diagnostic paracentesis performed within 12 hours (OR 0.51, 95% CI 0.32-0.79, P=0.003, I2=0%) or within 24 hours of admission (OR 0.67, 95% CI 0.45-0.98, P=0.04, I2=82%). Notably, the mortality OR was numerically lower when diagnostic paracentesis was performed within 12 hours, and the results were precise and homogenous (I2=0%).
CONCLUSIONS
Findings from this meta-analysis suggest that early diagnostic paracentesis is associated with better patient outcomes. Early diagnostic paracentesis within 12 hours of admission may be associated with the greatest mortality benefit. Data from large-scale randomized trials are needed to validate our findings, especially if there is a greater mortality benefit for early diagnostic paracentesis within 12 hours.

BACKGROUND
Extrahepatic, abdominal surgery in patients with cirrhosis is associated with high morbidity and mortality. This systematic review presents the current evidence available on the utility of a preoperative transjugular intrahepatic portosystemic shunt (TIPS), assessed by its effect on surgical candidacy and postoperative mortality and morbidity in patients with cirrhosis undergoing extrahepatic, abdominal surgery.
METHODS
MEDLINE, EMBASE, Cochrane Library and Web of Science databases were searched till 2022 to identify studies. Studies that reported characteristics and outcomes of participants with cirrhosis that had a TIPS inserted in preparation for extrahepatic, abdominal surgery, were included.
RESULTS
Twenty-one studies (292 patients) were included, of which three were comparative studies and the remaining case series or case reports. A TIPS was inserted in 190 patients prior to surgery. At least one clinical sign of portal hypertension identified by ascites, varices, and/or hepatic encephalopathy were present in all patients except one patient. Fifty eight percent had decompensated cirrhosis. TIPS insertion was successful in all patients. Eighty-nine percent of patients underwent surgery. The cumulative 30-day postoperative mortality was 2% (3/148). There were 97 complications reported in 168 patients (57%). In the three comparative studies, there was no difference in mortality or morbidity among patients who underwent TIPS prior to surgery compared to those who did not undergo TIPS prior to surgery.
CONCLUSION
Preoperative TIPS has been used to improve surgical candidacy in patients with cirrhosis undergoing extrahepatic, abdominal surgery, while reducing complications of portal hypertension. However, there is not enough evidence to support that TIPS insertion prior to extrahepatic, abdominal surgery significantly improves surgical outcomes in patients with cirrhosis and further studies are needed.

Review
The early management of neonates with meconium ileus (MI) and cystic fibrosis (CF) is highly variable across countries and is not standardized. We conducted a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses statement. The protocol was registered in PROSPERO (CRD42024522838). Studies from three providers of academic search engines were checked for inclusion criteria, using the following search terms: meconium ileus AND cystic fibrosis OR mucoviscidosis. Regarding the patient population studied, the inclusion criteria were defined using our predefined PICOT framework: studies on neonates with simple or complicated meconium which were confirmed to have cystic fibrosis and were conservatively managed or surgically treated. Results: A total of 566 publications from the last 10 years were verified by the authors of this review to find the most recent and relevant data, and only 8 met the inclusion criteria. Prenatally diagnosed meconium pseudocysts, bowel dilation, and ascites on ultrasound are predictors of neonatal surgery and risk factor for negative 12-month clinical outcomes in MI-CF newborns. For simple MI, conservative treatment with hypertonic solutions enemas can be effective in more than 25% of cases. If repeated enemas fail to disimpact the bowels, the Bishop-Koop stoma is a safe option. No comprehensive research has been conducted so far to determine the ideal surgical protocol for complicated MI. We only found three studies that reported the types of stomas performed and another study comparing the outcomes of patients depending on the surgical management; the conclusions are contradictory especially since the number of cases analyzed in each study was small. Between 18% and 38% of patients with complicated MI will require reoperation for various complications and the mortality rate varies between 0% and 8%. Conclusion: This study reveals a lack of strong data to support management decisions, unequivocally shows that the care of infants with MI is not standardized, and suggests a great need for international collaborative studies.

Digestive Diseases and Sciences Jun 2024Rebleeding is a significant complication of endoscopic injection of cyanoacrylate in gastric varices in cirrhotic patients.
BACKGROUND
Rebleeding is a significant complication of endoscopic injection of cyanoacrylate in gastric varices in cirrhotic patients.
AIM
This systematic review and meta-analysis aimed to evaluate the efficiency of endoscopic cyanoacrylate injection and summarized the risk factors for rebleeding.
METHODS
Databases were searched for articles published between January 2012 and December 2022. Studies evaluating the efficiency of endoscopic injection of cyanoacrylate glue for gastric varices and the risk factors for rebleeding were included.
RESULTS
The final analysis included data from 24 studies. The hemostatic rates ranged from 65 to 100%. The pooled rate of gastric varices recurrence was 34% [95% CI 21-46, I = 61.4%], early rebleeding rate was 16% [95% CI 11-20, I = 37.4%], late rebleeding rate was 39% [95% CI 36-42, I = 90.9%], mild and moderate adverse events rate were 28% [95% CI 24-31, I = 91.6%], 3% [95% CI - 2 to 8, I = 15.3%], rebleeding-related mortality rate was 6% [95% CI 2-10, I = 0%], all-cause mortality rate was 17% [95% CI 12-22, I = 63.6%]. Independent risk factors for gastric variceal rebleeding included portal venous thrombosis, ascites, cyanoacrylate volume, fever/systemic inflammatory response syndrome, red Wale sign, previous history of variceal bleeding, active bleeding and paragastric veins. The use of proton pump inhibitors could be a protective factor.
CONCLUSIONS
Endoscopic cyanoacrylate glue injection is an effective and safe treatment for gastric varices. Cirrhotic patients with the above risk factors may benefit from treatment aimed at reducing portal hypertension, antibiotic prophylaxis, and anticoagulation if they meet the indications.

Review
Chyloperitoneum arises from lymph leakage into the abdominal cavity, leading to an accumulation of milky fluid rich in triglycerides. Diagnosis can be challenging, and mortality rates vary depending on the underlying cause, with intestinal volvulus being just one potential acute cause. Despite its rarity, our case series highlights chyloperitoneum associated with non-ischemic small bowel volvulus. The aims of our study include assessing the incidence of this association and evaluating diagnostic and therapeutic approaches. We present two cases of acute abdominal peritonitis with suspected small bowel volvulus identified via contrast-enhanced computed tomography (CT). Emergency laparotomy revealed milky-free fluid and bowel volvulus. Additionally, we conducted a systematic review up to 31 October 2023, identifying 15 previously reported cases of small bowel volvulus and chyloperitoneum in adults (via the PRISMA scheme). Clarifying the etiopathogenetic mechanism of chyloperitoneum requires specific diagnostic tools. Magnetic resonance imaging (MRI) may be useful in non-emergency situations, while contrast-enhanced CT is employed in emergencies. Although small bowel volvulus infrequently causes chyloperitoneum, prompt treatment is necessary. The volvulus determines lymphatic flow obstruction at the base of the mesentery, with exudation and chyle accumulation in the abdominal cavity. Derotation of the volvulus alone may resolve chyloperitoneum without intestinal ischemia.

BACKGROUND
Abdominal compartment syndrome (ACS) is typically attributed to critically unwell patients with trauma, burns, post surgery, and massive ascites. A rare but fatal cause of ACS is bulimia nervosa (BN), which is an eating disorder characterized by bingeing, followed by methods to avoid weight gain, including purging.
CASE REPORT
We present a case of a 20-year-old woman who presented with abdominal pain and distension after consuming a large quantity of food the previous night and was unable to purge. She was initially managed conservatively and discharged home, but returned subsequently on the same day with clinical features of ACS secondary to acute gastric distension. Decompression resulted in life-threatening reperfusion injury with critical electrolyte abnormalities and fatal cardiac arrest in the operating theatre. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: A systematic review of the literature found only 11 case reports of ACS secondary to BN, of which only 6 patients survived due to early diagnosis and decompression. Inability to purge and lower limb ischemia appeared to be associated with increased mortality. As BN is a common emergency presentation, the case and systematic review highlights the need to consider ACS as a potentially life-threatening complication of binge eating, particularly when there is unsuccessful purging.

Review
Liver cirrhosis due to nonalcoholic steatohepatitis (NASH) is a life-threatening condition with increasing incidence world-wide. Although its symptoms are unspecific, it can lead to decompensation events such as ascites, hepatic encephalopathy, variceal hemorrhage, and hepatocellular carcinoma (HCC). In addition, an increased risk for cardiovascular events has been demonstrated in patients with NASH. Pharmacological treatments for NASH cirrhosis are not yet available, one of the reasons being the lack in surrogate endpoints available in clinical trials of NASH cirrhosis. The feasibility of non-invasive prognostic biomarkers makes them interesting candidates as possible surrogate endpoints if their change following treatment would result in better outcomes for patients in future clinical trials of NASH cirrhosis. In this systematic literature review, a summary of the available literature on the prognostic performance of non-invasive biomarkers in terms of cardiovascular events, liver-related events, and mortality is outlined. Due to the scarcity of data specific for NASH cirrhosis, this review includes studies on NAFLD whose evaluation focuses on cirrhosis. Our search strategy identified the following non-invasive biomarkers with prognostic value in studies of NASH patients: NAFLD fibrosis score (NFS), Fibrosis-4 (FIB-4), aspartate aminotransferase (AST) to platelet ratio index (APRI), enhanced liver fibrosis (ELF™), BARD (BMI, AST/ALT (alanine aminotransferase) ratio, diabetes), Hepamet Fibrosis Score (HFS), liver enzymes (AST + ALT), alpha-fetoprotein, platelet count, neutrophil to lymphocyte ratio (NLR), Lysyl oxidase-like (LOXL) 2, miR-122, liver stiffness, MEFIB (liver stiffness measured with magnetic resonance elastography (MRE) + FIB-4), and PNPLA3 GG genotype. The aim of the present systematic literature review is to provide the reader with a summary of the non-invasive biomarkers with prognostic value in NASH cirrhosis and give an evaluation of their utility as treatment monitoring biomarkers in future clinical trials.

INTRODUCTION
DNA methylation plays an important role in the carcinogenesis, progression, and prognosis of various human cancers. RASSF1A, BRCA1, APC, and p16 are the frequently methylated genes among patients with ovarian cancer. Therefore, our study aimed to better determine the prognostic and cancer characteristics effects of RASSF1A, BRCA1, APC, and p16 promoter methylation in ovarian cancer patients.
METHODS
Databases such as PubMed, Web of Science, EMBASE, CNKI, and WanFang were searched for published studies up to March 4, 2024. The outcomes are shown as OR and HR with their 95% CIs. Then, the random or fixed-effect model was performed to evaluate the effect sizes.
RESULTS
Finally, 27 articles were included in this meta-analysis. No significant relationships were observed between RASSF1A, BRCA1, and APC promoter methylation and the clinical prognostic (including overall survival and progression-free survival) and cancer characteristics (including ascites, lymph node metastasis, and pelvic peritoneal metastasis) in ovarian cancer. p16 promoter methylation was significantly related to poor progression-free survival (PFS) (HR = 1.52, 95% CI = 1.14-2.04) and overall survival (OS) (HR = 1.39, 95% CI = 1.06, to 1.83) in univariate and poor PFS in multivariate Cox regression models (HR = 1.42, 95% CI = 1.05-1.92). Besides, our results indicated that the clinical stage was associated with inferior OS while there was no significant association between tumor grade and OS.
CONCLUSION
RASSF1A, BRCA1, and APC promoter methylation were not significantly associated with clinical prognostic and cancer characteristics. p16 may be a useful biomarker for predicting PFS in ovarian cancer. Furthermore, the clinical stage was significantly associated with OS. In further research, more prospective and multicenter validation studies remain needed.

Review
BACKGROUND
Malignant Brenner tumors are rare ovarian tumors, accounting for less than 1% of malignant ovarian neoplasms. The aim of this manuscript is to systematically review the current literature concerning malignant Brenner tumors.
METHODS
We searched three medical databases (PubMed, Scopus, and Web of Science) for relevant articles published until 15 September 2023.
RESULTS
After applying inclusion and exclusion criteria, 48 manuscripts describing 115 cases were included in this study from the English literature.
CONCLUSIONS
We analyzed the demographic, clinical, pathological, and oncological characteristics of 115 patients with malignant Brenner tumors. The statistical analysis showed that recurrence was marginally statistically significantly related to tumor stage and was more common in patients with ascites and in women with abnormal CA-125 levels; patients that were treated with lymphadenectomy had better disease-specific survival.
