RESUMEN
Endoscopic Retrograde Cholangiopancreatography (ERCP) is the primary therapeutic procedure for pancreaticobiliary disorders, and studies highlighted the impact of papilla anatomy on its efficacy and safety. Our objective was to quantify the influence of papilla morphology on ERCP outcomes. We systematically searched three medical databases in September 2022, focusing on studies detailing the cannulation process or the rate of adverse events in the context of papilla morphology. The Haraldsson classification served as the primary system for papilla morphology, and a pooled event rate with a 95% confidence interval was calculated as the effect size measure. Out of 17 eligible studies, 14 were included in the quantitative synthesis. In studies using the Haraldsson classification, the rate of difficult cannulation was the lowest in type I papilla (26%), while the highest one was observed in the case of type IV papilla (41%). For post-ERCP pancreatitis, the event rate was the highest in type II papilla (11%) and the lowest in type I and III papilla (6-6%). No significant difference was observed in the cannulation failure and post-ERCP bleeding event rates between the papilla types. In conclusion, certain papilla morphologies are associated with a higher rate of difficult cannulation and post-ERCP pancreatitis.

BACKGROUND, AIMS: Patients with inflammatory bowel disease (IBD) have a more than twofold higher risk of venous thromboembolic events (VTE) than the general population. The etiology is complex, and the role of medication is not precisely defined.We aimed to assess the effect of anti-tumor necrosis factor alpha (anti-TNFα) drugs and conventional anti-inflammatory therapy, namely corticosteroids (CS), immunomodulators (IM), and 5-aminosalicylates (5-ASA) on VTE in IBD. METHODS: A systematic search was performed in five databases on the 22nd of November 2022. We included studies reporting VTE in the distinct categories of medications, determined the proportions, and calculated the odds ratios (OR) with 95% confidence intervals (CI), using the random-effects model. The risk of bias was evaluated with the Joanna Briggs Institute Critical Appraisal Checklist and the Risk of Bias in Non-randomized Studies of Interventions tool. RESULTS: The quantitative analysis included 16 observational studies, with data from 91,322 IBD patients. Patients receiving anti-TNFα medication had significantly less VTE (proportion: 0.05, CI: 0.02-0.10), than patients treated with CS (proportion: 0.16, CI: 0.07-0.32), with OR=0.42 (CI: 0.25-0.71). IMs resulted in similar proportions of VTE compared with biologics (0.05, CI: 0.03-0.10), with OR=0.94 (CI: 0.67-1.33). The proportion of patients receiving 5-ASA having VTE was 0.09 (CI: 0.04-0.20), with OR=1.00 (CI: 0.61-1.62). CONCLUSIONS: Biologics should be preferred over corticosteroids in cases of severe flare-ups and multiple VTE risk factors, as they are associated with reduced odds of these complications. Further studies are needed to validate our data.
RESUMEN
BACKGROUND: Hemodynamic instability and shock are associated with untoward outcomes in gastrointestinal bleeding. However, there are no studies in the existing literature on the proportion of patients who developed these outcomes after gastrointestinal bleeding. AIM: To determine the pooled event rates in the available literature and specify them based on the bleeding source. METHODS: The protocol was registered on PROSPERO in advance (CRD42021283258). A systematic search was performed in three databases (PubMed, EMBASE, and CENTRAL) on 14th October 2021. Pooled proportions with 95%CI were calculated with a random-effects model. A subgroup analysis was carried out based on the time of assessment (on admission or during hospital stay). Heterogeneity was assessed by Higgins and Thompson's I2 statistics. The Joanna Briggs Institute Prevalence Critical Appraisal Tool was used for the risk of bias assessment. The Reference Citation Analysis (https://www.referencecitationanalysis.com/) tool was applied to obtain the latest highlight articles. RESULTS: We identified 11589 records, of which 220 studies were eligible for data extraction. The overall proportion of shock and hemodynamic instability in general gastrointestinal bleeding patients was 0.25 (95%CI: 0.17-0.36, I2 = 100%). In non-variceal bleeding, the proportion was 0.22 (95%CI: 0.14-0.31, I2 = 100%), whereas it was 0.25 (95%CI: 0.19-0.32, I2 = 100%) in variceal bleeding. The proportion of patients with colonic diverticular bleeding who developed shock or hemodynamic instability was 0.12 (95%CI: 0.06-0.22, I2 = 90%). The risk of bias was low, and heterogeneity was high in all analyses. CONCLUSION: One in five, one in four, and one in eight patients develops shock or hemodynamic instability on admission or during hospitalization in the case of non-variceal, variceal, and colonic diverticular bleeding, respectively.

Background: Microscopic colitis (MC) is a chronic inflammatory disease of the large bowel characterized by watery diarrhea, substantially decreasing the patient's quality of life. Scarce data suggest that MC is associated with low bone density (LBD). Objectives: We aimed to assess whether MC is a risk factor for LBD and the proportion of patients with MC having LBD. Design: A systematic review and meta-analysis of studies reporting bone density measurements in MC patients. Data Sources and Methods: We systematically searched five databases from inception to October 16, 2021 (Pubmed, Embase, Cochrane, Scopus, and Web of Science). We used the random-effect model to calculate pooled odds ratios (ORs) and pooled event rates with 95% confidence intervals (CIs). To ascertain the quality of evidence of our outcomes, we followed the recommendations of the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Working Group. Results: The systematic search yielded a total of 3046 articles. Four articles were eligible for quantitative synthesis. All of them used age- and sex-matched controls to evaluate LBD occurrence among patients with MC. The odds of having LBD were twofold increased (OR = 2.13, CI: 1.42-3.20) in the presence of MC, the odds of osteopenia occurrence were 2.4 (OR = 2.45, CI: 1.11-5.41), and of osteoporosis 1.4 (OR = 1.42, CI: 0.65-3.12). The proportion of LBD was 0.68 (CI: 0.56-0.78), osteopenia was 0.51 (CI: 0.43-0.58), and osteoporosis was 0.11 (CI: 0.07-0.16) among the MC population. Our findings' certainty of the evidence was very low following the GRADEPro guideline. Conclusion: Our data demonstrate that MC is associated with a twofold risk for LBD. Based on our findings, we suggest screening patients for bone mineral density upon diagnosis of MC. Further prospective studies with higher patient numbers and longer follow-up periods on this topic are needed. Registration: Our protocol was prospectively registered with PROSPERO (CRD42021283392).
Investigating microscopic colitis as a risk factor for having low bone density in a literature overview and statistical approach Microscopic colitis (MC) is an underdiagnosed chronic inflammatory large bowel disease, characterized by watery diarrhea, which substantially impacts the patient's quality of life. The etiology of MC is still unclear but is suspected to be multifactorial. Moreover, low bone density (LBD) has been associated with the disease. Scarce data investigate the relationship of MC with LBD, although they share common risk factors, like advanced age and female sex. LBD has two forms; the mild is osteopenia and the severe form is osteoporosis. The most severe complications of osteoporosis are osteoporotic fractures, which can culminate in a life-threatening state and amplify the hospital expenses burden. Our primary aim was to assess if MC increases the risk of LBD. Furthermore, we estimated the proportions of bone mineral changes in the MC population. Following a rigorous methodology, our data suggest that MC doubles the odds of LBD. Furthermore, we have shown that two-thirds of the MC population suffers from bone density decrease, half of them have osteopenia, and one in 10 MC patients has osteoporosis. In conclusion, we highly suggest screening patients with MC for bone mineral density at the moment of diagnosis.
