Abstract

Background/purpose: The aim of this study is to clarify the relation between the incision size for endoscopic sphincterotomy (EST) and common bile duct stone (CBDS) recurrence. Methods: Patients who underwent elective endoscopic treatment for CBDS between January 2013 and December 2017 were enrolled, excluding those who met the exclusion criteria. The clinical characteristics were investigated using propensity score matching analysis. Results: A total of 243 patients were investigated. Propensity scores were calculated using multinomial logistic regression with five relevant variables (age, gender, follow‐up time, maximum stone size, and bile duct diameter), which led to extraction of 188 cases to compose cohorts of the small and medium EST incision groups. The CBDS recurrence rate was 17.0% in the small incision group and 6.4% in the medium incision group. Multivariate analysis identified the medium incision as an independent predictor of CBDS recurrence (hazard ratio 0.350, 95% confidence interval 0.133‐0.922, P =.034). The CBDS non‐recurrence rate of the medium incision group was significantly higher than that of the small incision group (log‐rank test P =.019). Conclusions: Our findings suggest that the CBDS recurrence rate was lower in EST with medium incision size than with small incision size. [ABSTRACT FROM AUTHOR]

Abstract

Background Gastrointestinal hemorrhage occurs frequently. We reviewed the tendency of occurrence of bleeding gastric and duodenal ulcers and their association with antithrombotic therapy before and after the widespread use of Evidence‐Based Clinical Practice Guidelines for Peptic Ulcer 2009 (1st edition), which was published to improve treatment outcomes and prevent peptic ulcers. Methods The study enrolled 1105 patients with bleeding gastric and duodenal ulcers treated at our hospital between January 2000 and March 2016. They were divided into the preguideline group (807 patients treated between January 2000 and December 2010) and the postguideline group (298 patients treated between January 2011 and March 2016). The use of medications, severity, the incidence of Helicobacter pylori infection, the presence of any underlying disease, and other factors were compared between the pre‐ and postguideline groups. Results The number of patients receiving antithrombotic therapy was slightly higher in the postguideline group without a significant difference (P = 0.50). The incidence of H. pylori infection was significantly lower in the postguideline group (P

Abstract

Summary: Background: The increasing incidence of older‐onset ulcerative colitis (UC), which has a higher risk of surgery, is a global health issue. However, data regarding intravenous steroid treatment, one of the important treatment options to avoid surgery, for older‐onset UC is lacking. Aims: To evaluate the association between onset age and effectiveness of intravenous steroids in UC. Methods: This retrospective multicentre (27 facilities) cohort study included moderate‐to‐severe hospitalised UC patients who underwent their first intravenous steroids between April 2014 and July 2019. The primary outcome was clinical remission at day 30, using two‐item patient‐reported outcome scoring. The key secondary outcomes were risks of surgery and adverse events (death, infection and venous thrombosis) within 90 days. A modified Poisson regression model was used for analysis. Results: Overall, 467 UC patients (384 younger‐onset and 83 older‐onset) were enrolled. Clinical remission at day 30 was observed in 252 (65.6%) among younger‐onset patients and 43 (51.8%) among older‐onset patients (adjusted risk difference, −21.7% [95% CI, −36.1% to −7.2%]; adjusted risk ratio [ARR], 0.74 [95% CI, 0.59 to 0.93]). The risks of surgery and adverse events were higher in older‐onset UC (20.5% vs. 3.1%; ARR, 8.92 [95% CI, 4.13 to 19.27], 25.3% vs. 9.1%; ARR, 2.19 [95% CI, 1.22 to 3.92], respectively). Four deaths occurred, all involving older‐onset UC. The risks of infection and venous thrombosis were also higher in older‐onset UC (18.1% vs. 8.6%, 7.2% vs. 0.5%, respectively). Conclusions: Older‐onset was associated with a lower effectiveness of intravenous steroids with higher risks of surgery and adverse events in UC. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: A few reports stating that differences in the various types of contrast media injected into the pancreatic duct are related to the onset of post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) have been published, and it was indicated that iodixanol which is a nonionic iodide radiographic contrast medium with a dimeric (2 dimers) structure may reduce the incidence of PEP. The aim of this retrospective study is to evaluate the usefulness of iodaxanol for prevention PEP in comparison with megulamine amidototrizoate. Methods: Two hundred and ninety-one patients were enrolled and divided into the 2 groups according to the contrast medium used. One hundred and fifty-five patients underwent ERCP with meglumine amidotrizoate, and 136 patients underwent ERCP with iodaxanol. The primary outcome of this study was the incidence of PEP associated with the use of each contrast medium. Results: In this study, comparison of the meglumine amidotrizoate treatment and iodaxanol treatment groups showed no significant difference with respect to the incidence of PEP. In addition, there was also no difference between the groups with respect to PEP severity. Conclusion: Our study suggested that iodaxanol does not necessarily contribute to the prevention of PEP in comparison with meglumine amidotrizoate. [ABSTRACT FROM AUTHOR]
