Meta-Analysis
Fibroblast growth factor-19 (FGF-19) is a gut hormone which interacts with metabolism and is depleted in obesity. There is some indication that the hormone undergoes a resurgence following bariatric surgery (BS), an effect which may contribute to the beneficial outcomes of such procedures. This systematic review and meta-analysis aims to synthesize the available literature on FGF-19 levels before and after BS. MEDLINE, Scopus and Web of Science databases were searched, and the effect of different surgical procedures and degrees of body mass index (BMI) reduction on FGF-19 levels was assessed by DerSimonian and Laird random-effects model in meta-analysis and dose-response analyses. This meta-analysis, which included 474 patients from 25 arms undergoing one of five BS procedures, revealed a significant increase in the levels of circulating FGF-19 following all-type BS. Vertical sleeve gastrectomy, duodenal-jejunal bypass liner and Roux-en-Y gastric bypass all significantly increased circulating FGF-19 levels from baseline. However, gastric banding failed to achieve the same, and in fact, biliopancreatic diversion was associated with decreased circulating FGF-19. Finally, an inverse association between FGF-19 and the degree of BMI-reduction post-operatively was noted. FGF-19 is increased by BS and may represent a pharmaceutical target in efforts to reproduce the beneficial effects of BS in a medical setting.

Comparative Study
Management of bleeding peptic duodenal ulcer refractory to endoscopic treatment: surgery or transcatheter arterial embolization as first-line therapy? A retrospective single-center study and systematic review.
BACKGROUND
The objective of this study was to compare the results of transcatheter arterial embolization (TAE) with surgery in terms of efficacy in the context of bleeding duodenal ulcer (BDU) refractory to endoscopic treatment.
MATERIALS AND METHODS
From January 2006 to December 2016, all patients treated for a BDU refractory to endoscopic treatment were included in this observational, comparative, retrospective, single-center study. Primary endpoint was the overall success of treatment of BDU requiring surgical and/or TAE. The secondary endpoints were pre-interventional data, recurrence rates, feasibility of secondary treatment, morbidity and mortality of surgical and radiological treatment, intensive care unit and length of stay. A systematic review of the literature was performed to compare results of surgery and TAE.
RESULTS
59 out of 396 patients (14.9%) treated for BDU required embolization and/or surgery: 15 patients underwent surgery (group S) including 7 patients after embolization failure and 44 patients underwent TAE (group TAE). The overall treatment success in intention to treat (85.7% vs 67.3%), per protocol (80% vs 79.5%) and bleeding recurrence rates (20% vs 15.9%) were also identical. Mortality (14.2% vs 15.3%) was similar between the two groups. Our study data were pooled with data from eight published studies and suggest that surgery have significant increased overall success (68.3% vs. 55.4%, p < 0.005).
CONCLUSION
The overall success rate was in favour of surgery according our meta-analysis. Our single-center study highlights the fact that predictive factors for recurrent bleeding after TAE must be identified to select good candidates for TAE and/or surgery.

Review
BACKGROUND
Post-pancreatectomy bleeding is a potentially fatal complication which results from the erosion of the regional visceral arteries, mainly the hepatic artery and stump of the gastro-duodenal artery, caused by a leak or fistula from the pancreatic anastomosis. The objective of this article is to assess whether wrapping of regional vessels with omentum or falciform/teres ligament following pancreaticoduodenectomy reduces the risk of extra-luminal bleeding.
MATERIALS AND METHOD
Standard medical electronic databases were searched with the help of a local librarian and relevant published randomised controlled trials (RCT) and any type of comparative trial were shortlisted according to the inclusion criteria. The summated outcome of post-operative extra-luminal bleeding in patients undergoing pancreaticoduodenectomy was evaluated using the principles of meta-analysis on RevMan 5 statistical software.
RESULT
Two RCTs and 5 retrospective studies on 4100 patients undergoing pancreaticoduodenectomy were found suitable for this meta-analysis. There were 1404 patients in the wrapping-group (WG) and 2696 patients in the no-wrapping group (NWG). In the random effects model analysis, the incidence of extra-luminal haemorrhage was statistically lower in WG [odds ratio 0.51, 95%, CI (0.31, 0.85), Z = 2.59, P = 0.01]. There was moderate heterogeneity between the studies; however it was not statistically significant.
CONCLUSION
The wrapping of regional vessels (using omentum, falciform ligament or ligamentum teres) following pancreaticoduodenectomy seems to reduce the risk of post-operative extra-luminal bleeding. However, more RCTs of robust quality recruiting a greater number of patients are required to validate these findings as this study presents the combined data of two RCTs and 5 retrospective studies.

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.

Prophylactic Clipping to Prevent Delayed Bleeding and Perforation After Endoscopic Submucosal Dissection and Endoscopic Mucosal Resection: A Systematic Review and Meta-analysis.
BACKGROUND AND AIMS
To help prevent delayed adverse events after endoscopic surgery, endoscopists often place clips at the site. This meta-analysis aimed to assess the efficacy and safety of prophylactic clipping in the prevention of delayed bleeding and perforation after endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR).
METHODS
Multiple databases were searched from the inception dates to April 2021. And we included all relevant studies. Pooled odds ratio comparing the prophylactic clipped group versus nonprophylactic clipped group were calculated using the random effects model.
RESULTS
Twenty-seven articles fulfilled the inclusion criteria, with a total size of 8693 participants. There was statistically significant difference in prophylactic clipping versus no prophylactic clipping for delayed bleeding and perforation found in all studies (odds ratio: 0.35, 95% confidence interval: 0.25-0.49, P <0.01; odds ratio: 0.42, 95% confidence interval: 0.21-0.83, P <0.05; respectively). Besides, statistically significant difference was also found in subgroup analyses based on patients with lesions larger than 20 mm. Prophylactic clipping was more protective for duodenal delayed adverse events than colorectum. The use of clip closure was more protective to ESD-related delayed adverse events than EMR.
CONCLUSIONS
Prophylactic clipping after ESD and EMR was beneficial in preventing delayed bleeding and perforation.

Meta-Analysis
BACKGROUND
The mainstay of surgical management of perforated peptic ulcer is omental patch repair. Advances in minimally invasive techniques have shown feasibility of laparoscopic omental patch repair (LOPR). Laparoscopic omental patch repair is limited by learning curve (LC), but there is a lack of reporting of LC in LOPR. This study aims to compare outcomes following LOPR versus open omental patch repair (OOPR) with reporting of LC.
METHODS
PubMed, Embase, The Cochrane Library, and Scopus were systematically searched from inception till January 2022 for randomized controlled trials (RCTs) and non-RCTs comparing LOPR and OOPR in perforated peptic ulcer. Exclusion criteria were primary repair without use of omental patch repair. Primary outcomes were 30-day mortality, postoperative leak, and LC analysis.
RESULTS
There were a total of 29 studies including 5,311 patients (LOPR, n = 1,687; OOPR, n = 3,624), with 4 RCTs with 238 patients (LOPR, n = 118; OOPR, n = 120). Majority of ulcers were located in the duodenum (57.0%) followed by stomach (30.7%). Mean ulcer size ranged from 5 to 16.2 mm in LOPR and 4.7 to 15.8 mm in OOPR. Laparoscopic omental patch repair was associated with lower 30-day mortality (odds ratio [OR], 0.57; 95% confidence interval [CI], 0.35-0.92; p = 0.02), overall morbidity (OR, 0.31; 95% CI, 0.18-0.53; p < 0.0001), surgical site infection (OR, 0.27; 95% CI, 0.18-0.42; p < 0.00001), and length of stay (mean difference, -2.84 days; 95% CI, -3.63 to -2.06; p < 0.00001). Postoperative leakage (OR, 1.06; 95% CI, 0.43-2.61; p = 0.90) was comparable between LOPR and OOPR. Only three studies analyzed the proportion of consultants to trainees; LOPR was performed mainly by consultants (range, 82.4-91.4%), while OOPR was mainly performed by trainees (range, 52.8-96.8%). One study showed that consultants who performed open conversion had shorter operating time compared with chief residents (85 vs. 186.6 minutes, p < 0.003).
CONCLUSION
Laparoscopic omental patch repair has lower mortality, overall morbidity, length of stay, intraoperative blood loss, and postoperative pain compared with OOPR. More prospective studies should be conducted to evaluate LC in LOPR.

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.

ETHNOPHARMACOLOGICAL RELEVANCE
Different orchids are important in traditional medicine, and species belonging to the genus Bletilla are important. Bletilla species have been used for thousands of years in Traditional Chinese Medicine (TCM) for the treatment of several health disorders, such as gastrointestinal disorders, peptic ulcer, lung disorders, and traumatic bleeding etc. AIM OF THIS REVIEW: This review aims to provide a systematic overview and objective analysis of Bletilla species and to find the probable relationship between their traditional use, chemical constituents, and pharmacological activities, while assessing their therapeutic potential in treatment of different human diseases.
MATERIALS AND METHODS
Relevant literatures on Bletilla species have been collected using the keywords "Bletilla", "phytochemistry", and "pharmacology" in scientific databases, such as "PubMed", "Scifinder", "The Plant List", "Elsevier", "China Knowledge Resource Integrated databases (CNKI)", "Google Scholar", "Baidu Scholar", and other literature sources, etc. RESULTS: This review indicates the isolation and identification of over 261 compounds from this genus, till December 2020. These chemical isolates belong to the stilbenes (bibenzyls and phenanthrenes), flavonoids, triterpenoids, steroids, simple phenolics, and glucosyloxybenzyl 2-isobutylmalates classes of compounds. These compounds have been reported to be characteristically distributed in Bletilla striata (Thunb.) Rchb. f. (BS), Bletilla ochracea Schltr. (BO), and Bletilla formosana (Hayata) Schltr. (BF). The crude extracts and pure compounds derived from the three Bletilla species have reportedly exhibited a wide spectrum of in vitro and in vivo pharmacological effects, such as hemostatic, anti-inflammatory, anti-tumor, and anti-microbial activities. As a Traditional Chinese Medicine (TCM), Bletilla species or preparations containing Bletilla species have been used for the treatment of epistaxis, gastrointestinal bleeding, cough and hemoptysis, gastric and duodenal ulcer, and traumatic injuries. Thus, Bletilla species have proven potential both in traditional uses and scientific studies.
CONCLUSIONS
Pharmacological studies have validated the use of Bletilla species in the traditional medicine, especially hemorrhagic diseases. Polysaccharides and stilbenes are the major bioactive chemical constituents of Bletilla genus according to the literatures. However, the mechanism of action of these molecules is yet to be studied. In addition, a detailed comparative analysis of the phytochemistry and biological activities of the three Bletilla species (BS, BO and BF) is highly recommended for understanding their ethnopharmacological uses and applications in clinics. Clinical toxicity tests on BS have been found to be negative, but it can't be used with Aconitum carmichaeli in traditional uses. Furthermore, not many reports are present in the literature regarding the conservation of Bletilla species.

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.
