Meta-Analysis Review
Cystic pancreatic neuroendocrine tumors represent 13% of all neuroendocrine tumors. The aim of this study is to analyze the phenotype and biologic behavior of resected cystic neuroendocrine tumors. A systematic review and meta-analysis were conducted until September 2016 using a search in Medline, Scopus, and EMBASE with the terms "cystic pancreatic endocrine neoplasm", "cystic islets tumors" and "cystic islets neoplasms". From the 795 citations recovered 80 studies reporting on 431 patients were selected. 87.1% (n = 387) were sporadic tumors and 10.3% (n = 40) corresponded to multiple endocrine neoplasia endocrine type 1. Were diagnosed incidentally 44.6% (n = 135). Cytology was found to have a sensitivity of 78.5%. Were non-functional tumors 85% (n = 338), and among the functional tumors, insulinoma was the most frequent. According to the European Neuroendocrine Tumor Society staging, 87.8% were limited to the pancreas (I-IIb), and 12.2% were advanced (III-IV). Disease-free survival at 5 years in stages (I-IIIa) and (IIIb-IV) was 91.5% and 54.2%, respectively; and was significantly lower (p = 0.0001) in functional tumors. In patients with multiple endocrine neoplasia there was a higher incidence of functional (62.5%) and multifocal (28.1%) tumors. Disease-free survival at 5 and 10 years was 60%. Cystic pancreatic neuroendocrine tumors exhibit phenotypical characteristics which are different to those of solid neuroendocrine tumors.

Health Technology Assessment... Jul 2023Magnetic resonance imaging-based technologies are non-invasive diagnostic tests that can be used to assess non-alcoholic fatty liver disease.
BACKGROUND
Magnetic resonance imaging-based technologies are non-invasive diagnostic tests that can be used to assess non-alcoholic fatty liver disease.
OBJECTIVES
The study objectives were to assess the diagnostic test accuracy, clinical impact and cost-effectiveness of two magnetic resonance imaging-based technologies (LiverMultiScan and magnetic resonance elastography) for patients with non-alcoholic fatty liver disease for whom advanced fibrosis or cirrhosis had not been diagnosed and who had indeterminate results from fibrosis testing, or for whom transient elastography or acoustic radiation force impulse was unsuitable, or who had discordant results from fibrosis testing.
DATA SOURCES
The data sources searched were MEDLINE, MEDLINE Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Database of Controlled Trials, Database of Abstracts of Reviews of Effects and the Health Technology Assessment.
METHODS
A systematic review was conducted using established methods. Diagnostic test accuracy estimates were calculated using bivariate models and a summary receiver operating characteristic curve was calculated using a hierarchical model. A simple decision-tree model was developed to generate cost-effectiveness results.
RESULTS
The diagnostic test accuracy review (13 studies) and the clinical impact review (11 studies) only included one study that provided evidence for patients who had indeterminate or discordant results from fibrosis testing. No studies of patients for whom transient elastography or acoustic radiation force impulse were unsuitable were identified. Depending on fibrosis level, relevant published LiverMultiScan diagnostic test accuracy results ranged from 50% to 88% (sensitivity) and from 42% to 75% (specificity). No magnetic resonance elastography diagnostic test accuracy data were available for the specific population of interest. Results from the clinical impact review suggested that acceptability of LiverMultiScan was generally positive. To explore how the decision to proceed to biopsy is influenced by magnetic resonance imaging-based technologies, the External Assessment Group presented cost-effectiveness analyses for LiverMultiScan plus biopsy versus biopsy only. Base-case incremental cost-effectiveness ratio per quality-adjusted life year gained results for seven of the eight diagnostic test strategies considered showed that LiverMultiScan plus biopsy was dominated by biopsy only; for the remaining strategy (Brunt grade ≥2), the incremental cost-effectiveness ratio per quality-adjusted life year gained was £1,266,511. Results from threshold and scenario analyses demonstrated that External Assessment Group base-case results were robust to plausible variations in the magnitude of key parameters.
LIMITATIONS
Diagnostic test accuracy, clinical impact and cost-effectiveness data for magnetic resonance imaging-based technologies for the population that is the focus of this assessment were limited.
CONCLUSIONS
Magnetic resonance imaging-based technologies may be useful to identify patients who may benefit from additional testing in the form of liver biopsy and those for whom this additional testing may not be necessary. However, there is a paucity of diagnostic test accuracy and clinical impact data for patients who have indeterminate results from fibrosis testing, for whom transient elastography or acoustic radiation force impulse are unsuitable or who had discordant results from fibrosis testing. Given the External Assessment Group cost-effectiveness analyses assumptions, the use of LiverMultiScan and magnetic resonance elastography for assessing non-alcoholic fatty liver disease for patients with inconclusive results from previous fibrosis testing is unlikely to be a cost-effective use of National Health Service resources compared with liver biopsy only.

Meta-Analysis Review
PURPOSE
to review recent literature concerning long-term health issues and transitional care in esophageal atresia (EA) patients. PubMed, Scopus, Embase and Web of Science databases were screened for studies regarding EA patients aged more than or equal to 11 years, published between August 2014 and June 2022. Sixteen studies involving 830 patients were analyzed. Mean age was 27.4 years (range 11-63). EA subtype distribution was: type C (48.8%), A (9.5%), D (1.9%), E (0.5%) and B (0.2%). 55% underwent primary repair, 34.3% delayed repair, 10.5% esophageal substitution. Mean follow-up was 27.2 years (range 11-63). Long-term sequelae were: gastro-esophageal reflux (41.4%), dysphagia (27.6%), esophagitis (12.4%), Barrett esophagus (8.1%), anastomotic stricture (4.8%); persistent cough (8.7%), recurrent infections (4.3%) and chronic respiratory diseases (5.5%). Musculo-skeletal deformities were present in 36 out of 74 reported cases. Reduced weight and height were detected in 13.3% and 6% cases, respectively. Impaired quality of life was reported in 9% of patients; 9.6% had diagnosis or raised risk of mental disorders. 10.3% of adult patients had no care provider. Meta-analysis was conducted on 816 patients. Estimated prevalences are: GERD 42.4%, dysphagia 57.8%, Barrett esophagus 12.4%, respiratory diseases 33.3%, neurological sequelae 11.7%, underweight 19.6%. Heterogeneity was substantial (> 50%). Conclusion: EA patients must continue follow-up beyond childhood, with a defined transitional-care path by a highly specialized multidisciplinary team due to the multiple long-term sequelae.
WHAT IS KNOWN
• Survival rates of esophageal atresia patients is now more than 90% thanks to the improvements in surgical techniques and intensive care, therefore patients' needs throughout adolescence and adulthood must be taken into account.
WHAT IS NEW
• This review, by summarizing recent literature concerning long term sequelae of esophageal atresia, may contribute to raise awareness on the importance of defining standardized protocols of transitional and adulthood care for esophageal atresia patients.

Meta-Analysis Review
INTRODUCTION
The independent effect of exercise on liver histology in non-alcoholic fatty liver disease (NAFLD) remains unclear. As such, we conducted a systematic review and meta-analysis of the effect of exercise alone on histological endpoints in biopsy-proven NAFLD.
MATERIALS AND METHODS
A systematic literature search was conducted to include controlled clinical trials investigating the effect of exercise alone on liver histology in biopsy-proven NAFLD. Meta-analysis was conducted for histological outcomes with available data from a minimum of three studies. Pooled estimates of the effect of exercise on histological endpoints were calculated using random-effects models.
RESULTS
We identified three controlled clinical trials that assessed the independent effect of exercise on histological outcomes in patients with biopsy-proven NAFLD. The studies consisted of 72 total participants, including 40 subjects in the exercise intervention and 32 individuals in the comparison group. Meta-analysis showed that exercise did not significantly improve Brunt grade, NAFLD activity score, and fibrosis in NAFLD.
DISCUSSION
Exercise alone may not lead to significant histopathological improvement in NAFLD. Future well-powered randomized controlled trials are needed to better characterize the impact of exercise on histological outcomes and clinical endpoints.

Review
Inflammatory bowel disease (IBD) is a chronic condition and mainly affects the intestines, however, the involvement of the other organs of the gastrointestinal tract (upper part, pancreas, and liver) have been observed. The coexistence of IBD with pancreatic pathology is rare, however, it has been diagnosed more frequently during recent years in the pediatric population. This article reviews the current literature on the most common pancreatic diseases associated with IBD in the pediatric population and their relationship with IBD activity and treatment. We performed a systematic review of data from published studies on pancreatic disorders, also reported as extraintestinal manifestations (EIMs), among children with IBD. We searched PubMed and Web of Science to identify eligible studies published prior to 25 April 2020. Forty-four papers were chosen for analysis after a detailed inspection, which aimed to keep only the research studies (case control studies and cohort studies) or case reports on children and only those which were written in English. The manifestations of IBD-associated pancreatic disorders range from asymptomatic increase in pancreatic enzymes activity to severe disease such as acute pancreatitis. Acute pancreatitis (AP) induced by drugs, mainly thiopurine, seems to be the most- often-reported pancreatic disease associated with IBD in children. AP associated with other than drug etiologies, and chronic pancreatitis (CP), are rarely observed in the course of pediatric IBD. The pancreatic involvement can be strictly related to the activity of IBD and can also precede the diagnosis of IBD in some pediatric patients. The course of AP is mild in most cases and may occasionally lead to the development of CP, mainly in cases with a genetic predisposition. The involvement of the pancreas in the course of IBD may be considered as an EIM or a separate co-morbid disease, but it can also be a side effect of IBD therapy, therefore a differential diagnosis should always be performed. As the number of IBD incidences with concomitant pancreatic diseases is constantly increasing in the pediatric population, it is important to include pancreatic enzymes level measurement in the workup of IBD.

Meta-Analysis Review
PURPOSE
Surgical strategies for perforated diverticulitis (Hinchey stages III and IV) remain controversial. This systematic review aimed to compare the outcome of primary anastomosis, Hartmann procedure and laparoscopic lavage.
METHODS
A systematic literature search was conducted through Medline, Embase, Cochrane Central Register and Health Technology Assessment Database to identify randomized and non-randomized controlled trials involving patients with perforated left-sided colonic diverticulitis comparing different surgical strategies. The methodological quality of the included studies was assessed systematically (Grading of Recommendations, Assessment, Development and Evaluation) and a meta-analysis was performed.
RESULTS
After screening 4090 titles and abstracts published between 1958 and January 2018, 148 were selected for full text assessment. Sixteen trials (7 RCTs, 9 non-RCTs) with 1223 patients were included. Mortality rates were not significantly different between Hartmann procedure and primary anastomosis for Hinchey III and IV, neither in the meta-analysis of three RCTs (RR 2.03 (95% CI 0.79 to 5.25); p = 0.14, moderate quality of evidence) nor in the meta-analysis of six observational studies (RR 1.53 (95% CI 0.89 to 2.65); p = 0.13, very low quality of evidence). However, stoma reversal rates were significantly higher in the primary anastomosis group (RR 0.73 (95% CI 0.58 to 0.98); p = 0.008, moderate quality of evidence). Meta-analysis of four RCTs showed no significant difference between laparoscopic lavage for Hinchey III compared to sigmoid resection neither for mortality (RR 1.07 (95% CI 0.65 to 1.76); p = 0.79, moderate quality of evidence) nor for major complications (RR 0.86 (95% CI 0.69 to 1.08); p = 0.20, moderate quality of evidence).
CONCLUSIONS
This systematic review suggests similar rates of complications but higher rates of colonic restoration after primary anastomosis compared to Hartmann procedure in perforated diverticulitis with generalized peritonitis (Hinchey III and IV). Results in laparoscopic lavage for Hinchey III are not superior to primary resection. However, further studies with a careful interpretation of the meaning of re-interventions are required.

Meta-Analysis Review
Downstaging can facilitate liver transplantation (LT) for patients outside of Milan criteria with hepatocellular carcinoma (HCC); however, the optimal protocol and downstaging outcomes are poorly defined. We aimed to characterize rates of successful downstaging to within Milan criteria and post-LT recurrence and survival among patients who underwent downstaging. We performed a systematic literature review using the MEDLINE and Embase databases from January 1996 through March 2015 and a search of national meeting abstracts from 2010 to 2014. Rates of downstaging success (defined as a decrease of tumor burden to within Milan) and post-LT recurrence with 95% confidence intervals (CIs) were calculated. Prespecified subgroup analyses were conducted by treatment modality, study design, and patient characteristics. Thirteen studies (n = 950 patients) evaluating downstaging success had a pooled success rate of 0.48 (95% CI, 0.39-0.58%). In subgroup analyses, there was no significant difference comparing transarterial chemoembolization (TACE) versus transarterial radioembolization (TARE; P = 0.51), but there were higher success rates in prospective versus retrospective studies (0.68 versus 0.44; P < 0.001). The 12 studies (n = 320 patients) evaluating post-LT HCC recurrence had a pooled recurrence rate of 0.16 (95% CI, 0.11-0.23). There was no significant difference in recurrence rates between TACE and TARE (P = 0.33). Post-LT survival could not be aggregated because of heterogeneity in survival data reporting. Current data have heterogeneity in baseline tumor burden, waiting time, downstaging protocols, and treatment response assessments. There are also notable limitations including inconsistent reporting of inclusion criteria, downstaging protocols, and outcome assessment criteria. In conclusion, the success rate of downstaging HCC to within Milan criteria exceeds 40%; however, posttransplant HCC recurrence rates are high at 16%. Downstaging protocols for HCC should be systematically studied and optimized to minimize the risk of post-LT HCC recurrence.

Meta-Analysis Review
BACKGROUND & AIMS
Alcohol is one of the leading causes of hepatocellular carcinoma (HCC). However, pooled estimates of HCC incidence in alcohol-associated cirrhosis have not been evaluated systematically. We performed a pooled analysis of time-to-event data to provide robust estimates for the incidence of HCC in alcohol-associated cirrhosis.
METHODS
Medline, Embase, Cochrane Central Register, Scopus, and Web of Science were searched from inception to August 2021. Individual patient data were reconstructed from published Kaplan-Meier curves, and a pooled analysis of cumulative HCC incidence was performed using a random-effects model.
RESULTS
We screened 5022 articles and included 18 studies (148,333 patients). In the pooled analysis, the cumulative incidence of HCC in alcohol-associated cirrhosis at 1, 5, and 10 years among studies that accounted for the competing risk of death without HCC was 1%, 3%, and 9%, respectively. A secondary analysis by traditional meta-analysis determined that the HCC incidence rate was higher in cohorts enrolled in a HCC surveillance program (18.6 vs 4.8 per 1000 person-years; P = .001) vs those who were not enrolled in a surveillance program. Meta-regression showed that diabetes, smoking, variceal bleeding, and hepatic decompensation were associated with a higher risk of HCC.
CONCLUSIONS
Our analysis determined that the 5- and 10- year cumulative risk of HCC in alcohol-associated cirrhosis was 3% and 9%, respectively, with a higher incidence in cohorts that were enrolled in a HCC surveillance program. These data should be validated further in large prospective studies, and may have important implications for HCC screening and surveillance among patients with alcohol-associated cirrhosis.

Meta-Analysis Review
Achalasia(AC) is an esophageal motility disorder characterized by decreased esophageal motility and impaired relaxation of lower esophageal sphincter(LES). The treatment of achalasia is continuously improved for the development of technology, but each treatment has its own advantages and disadvantages. This article was to compare the efficacy and complication of different treatment on AC. PUBMED/MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials were searched for eligible studies. A random-effects model within a Bayesian framework was applied to compare treatment effects as odds ratio (OR) with their corresponding 95% credible interval (CI), also OR was applied to compare complication with 95% CI. The surface under the cumulative ranking area (SUCRA) was calculated to make the ranking of the treatments for outcomes. Twenty-seven randomized controlled trials (RCTs) were eligible. According to SUCRA ranking, anterior peroral endoscopic myotomy (APOEM) (SUCRA = 84.6%) might have the highest probability to be the best treatment for dysphagia remission in AC patients, followed by POEM (SUCRA = 78.4%). For gastroesophageal reflux disease (GERD) assessment, the corresponding SUCRA values indicated that botulinum toxin(BT) (SUCRA = 18.3%) might have lowest GERD incidence rate and POEM ranked the worst (SUCRA = 69.8%).. APOEM might have the highest probability to be the best therapeutic strategy for dysphagia remission in a short-term of follow-up, but the GERD incidence rate was high. BT injection might have the lowest probability to treat dysphagia, but the risk of GERD was the lowest. In the future, more RCTs with higher qualities are needed to make head-to-head comparison between 2 or more treatments.

Review
BACKGROUND
Cystic fibrosis is an autosomal recessive inherited defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene resulting in abnormal regulation of salt and water movement across the membranes. In the liver this leads to focal biliary fibrosis resulting in progressive portal hypertension and end-stage liver disease in some individuals. This can be asymptomatic, but may lead to splenomegaly and hypersplenism, development of varices and variceal bleeding, and ascites; it has negative impact on overall nutritional status and respiratory function in this population. Prognosis is poor once significant portal hypertension is established. The role and outcome of various interventions for managing advanced liver disease (non-malignant end stage disease) in people with cystic fibrosis is currently unidentified.
OBJECTIVES
To review and assess the efficacy of currently available treatment options for preventing and managing advanced liver disease in children and adults with cystic fibrosis.
SEARCH METHODS
We searched the Cochrane Cystic Fibrosis Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books.Date of last search: 06 April 2017.We also searched the reference lists of relevant articles and reviews and online trials registries. Date of last search: 04 January 2017.
SELECTION CRITERIA
Any published and unpublished randomised controlled trials and quasi-randomised controlled trials of advanced liver disease in cystic fibrosis with cirrhosis or liver failure, portal hypertension or variceal bleeding (or both).
DATA COLLECTION AND ANALYSIS
Authors independently examined titles and abstracts to identify potentially relevant trials, but none were eligible for inclusion in this review.
MAIN RESULTS
A comprehensive search of the literature did not identify any published eligible randomised controlled trials.
AUTHORS' CONCLUSIONS
In order to develop the best source of evidence, there is a need to undertake randomised controlled trials of interventions for preventing and managing advanced liver disease in adults and children with cystic fibrosis.
