Meta-Analysis
A systematic review and meta-analysis were performed to estimate the incidence of possible complications following EUS-guided pancreas biopsy. Pancreatic cancer has a very poor prognosis with a high fatality rate. Early diagnosis is important to improve the prognosis of pancreatic cancer. We searched Pubmed, Embase, Web of Science, and Scopus databases for studies published from inception to Augest, 2018. Meta-analysis were conducted with random-effect models and heterogeneity was calculated with the Q, I and τ statistics. We enrolled 78 studies from 71 articles in the meta-analysis, comprising 11,652 patients. Pooled data showed that the whole complication incidences were low 0.210 × 10(95%CI -0.648 × 10, 1.068 × 10). And they were in bleeding 0.002 × 10 (95%CI -0.092 × 10, 0.097 × 10), pancreatitis 0.002 (95%CI -0.082 × 10, 0.086 × 10), abdominal pain 0 (95%CI -0.037 × 10, 0.038 × 10), fever 0 (95%CI -0.032 × 10, 0. 032 × 10), infection 0 (95%CI -0.030 × 10, 0.031 × 10), duodenal perforation 0 (95%CI -0.033 × 10, 0.034 × 10), pancreatic fistula 0 (95%CI -0.029 × 10, 0.029 × 10), abscess 0 (95%CI -0.029 × 10, 0.029 × 10) and sepsis 0 (95%CI -0.029 × 10, 0.030 × 10). Subgroup analysis based on the tumor size, site, needle type and tumor style also showed robust results. The pooled data showed EUS-guided pancreas biopsy could be a safe approach for the diagnosis of pancreatic lesions. More large-scale studies will be necessary to confirm the findings across different population.

Meta-Analysis
Systematic Review and Meta-Analysis: Accuracy of Both Gamma Delta+ Intraepithelial Lymphocytes and Coeliac Lymphogram Evaluated by Flow Cytometry for Coeliac Disease Diagnosis.
UNLABELLED
It has been suggested that in doubtful cases of coeliac disease, a high CD3 T-cell receptor gamma delta (TCRγδ) intraepithelial lymphocyte count increases the likelihood of coeliac disease.
AIM
To evaluate the diagnostic accuracy of both an isolated increase of TCRγδ cells and a coeliac lymphogram (increase of TCRγδ decrease of CD3 intraepithelial lymphocytes) evaluated by flow cytometry in the diagnosis of coeliac disease.
METHODS
The literature search was conducted in MEDLINE and EMBASE. The inclusion criteria were: an article that allows for the construction of a 2 × 2 table of true and false positive and true and false negative values. A diagnostic accuracy test meta-analysis was performed.
RESULTS
The search provided 49 relevant citations, of which 6 were selected for the analysis, which represented 519 patients and 440 controls. Coeliac lymphogram: The pooled S and Sp were 93% and 98%, without heterogeneity. The area under the SROC curve (AUC) was 0.98 (95% CI, 0.97-0.99). TCRγδ: Pooled S and Sp were both 95%, with significant heterogeneity. The AUC was 0.97 (95% CI, 0.95-0.98). : Both TCRγδ count and coeliac lymphogram assessed by flow cytometry in duodenal mucosal samples are associated with a high level of diagnostic accuracy for and against coeliac disease.

Meta-Analysis
We aimed to estimate the seroprevalence and the prevalence of coeliac disease (CD) in women with reproductive problems. A systematic review of English published articles until June 2019 was performed in PubMed and Scopus using the terms: (infertility and (coeliac disease OR gluten) OR (miscarriage and (coeliac disease OR gluten) OR (abortion and (coeliac disease OR gluten). All articles showing numerical data of anti-transglutaminase type 2 or anti-endomisium antibodies, or intestinal biopsy information were included. The study group comprised women with overall infertility, unexplained infertility, or recurrent spontaneous abortions. Two authors independently performed data extraction using a predefined data sheet. The initial search yielded 310 articles, and 23 were selected for data extraction. After meta-analysis, the pooled seroprevalence was very similar for overall and unexplained infertility, with a pooled proportion of around 1.3%-1.6%. This implies three times higher odds of having CD in infertility when compared to controls. The pooled prevalence could not be accurately calculated due to the small sample sizes. Further studies with increased sample sizes are necessary before giving specific recommendations for CD screening in women with reproductive problems, but current data seem to support a higher risk of CD in these women.

Comparative Study Meta-Analysis
In cases of difficult biliary cannulation, transpancreatic sphincterotomy (TPS) can be an alternative approach of biliary access. However, its success and safety profile have not been studied in detail. A systematic review and meta-analysis were performed to study the overall cannulation success and adverse events of TPS. These outcomes were also compared to other advanced cannulation methods. A systematic literature search was conducted to find all relevant articles containing data on TPS. Successful biliary cannulation and complications rates [post-ERCP pancreatitis (PEP), bleeding, and perforation rates] were compared in the pooled analyses of prospective comparative studies. The overall outcomes were calculated involving all studies on TPS. TPS was superior compared to needle-knife precut papillotomy (NKPP) and the double-guidewire method (DGW) regarding cannulation success (odds ratio [OR] 2.32; 95% confidence interval [CI] 1.37-3.93; and OR 2.72; 95% CI 1.30-5.69, respectively). The rate of PEP did not differ between TPS and NKPP or DGW; however, TPS (only retrospective studies were available for comparison) proved to be worse than needle-knife fistulotomy in this regard (OR 4.62; 95% CI 1.36-15.72). Bleeding and perforation rates were similar among these advanced techniques. There were no data about long-term consequences of TPS. The biliary cannulation rate of TPS is higher than that of the other advanced cannulation techniques, while the safety profile is similar to those. However, no long-term follow-up studies are available on the later consequences of TPS; therefore, such studies are strongly needed for its full evaluation.

Meta-Analysis Review
The purpose of this study is to assess the clinical outcomes and prognostic factors for survival of patients with duodenal gastrointestinal stromal tumors (GIST) who underwent pancreaticoduodenectomy (PD) or local resection (LR). PubMed database was searched for relevant studies. A meta-analysis was performed with Review Manager 5.3 software. Twenty-seven observational studies involving 1103 patients were included in the review. The overall morbidity and 30-day mortality was 27% and 0.5% respectively. The median (range) 5-year overall survival (OS) and disease-free survival (DFS) rates were 87% (60-100%) and 71% (44-100%) respectively. In meta-analyses, factors associated with shorter DFS included male sex, mitotic index >5/50 high-power fields, high risk, tumor size >5 cm, and the PD procedure. Factors associated with shorter OS included mitotic index >5/50 high-power fields and tumor size >5 cm. Patients in PD group had a higher incidence of mitotic index >5/50 HPF, a higher incidence of high-risk classification, a higher incidence of tumors in the second portion of the duodenum, a larger tumor size, a longer duration of operation, more intraoperative blood loss, a greater blood transfusion requirement, a higher morbidity rate, a longer hospital stay, and an increased recurrence rate than those in LR group. In conclusion, the current literature review demonstrates that the postoperative prognosis of duodenal GIST is promising and mainly affected by tumor factors. The choice of the surgical approach should depend on the anatomical location and tumor size.

Meta-Analysis
BACKGROUND AND AIMS
Endoscopic biliary sphincterotomy (EST) is commonly performed during therapeutic endoscopic retrograde cholangiopancreatography (ERCP), but is an independent risk factor for post-ERCP pancreatitis, bleeding and duodenal perforation. These are partly ascribed to the electrosurgical current mode used for EST, and currently the optimal current model for EST remains controversial. In this study, we aimed to compare the rate of complications undergoing EST using the Endocut versus the blended current.
METHODS
A systematic search of databases was performed for relevant published and prospective studies including randomized clinical trials (RCTs) to compare Endocut with blended current modes for EST. Data were collected from inception until 1 July 2018, using post-ERCP pancreatitis, bleeding and perforation as primary outcomes.
RESULTS
Three RCTs including a total of 594 patients met the inclusion criteria. Our meta-analysis results showed the rate of post-ERCP pancreatitis, primarily mild to moderate pancreatitis, was no different between Endocut versus blended current modes [risk ratio (RR) 0.61, 95% confidence interval (CI) 0.25-1.52, P = 0.29]. However, the risk of endoscopically bleeding events, primarily mild bleeding, was lower in studies using Endocut versus blended current (RR 0.54, 95% CI 0.31-0.95, P = 0.03). Notably, none of the patients experienced perforation in these three trials.
CONCLUSIONS
The rate of post-ERCP pancreatitis was not significantly different when using the Endocut versus blended current during EST. Nevertheless, compared with the blended current, Endocut reduced the incidence of endoscopically evident bleeding; however, the available data were insufficient to assess the perforation risk.
