Background: Despite accumulating evidence and recommendations for management of colonic diverticular bleeding (CDB), the changes in its clinical management and outcomes remain unknown.
Methods: We performed a retrospective tendency analysis on a biennial basis, a propensity score-matched cohort study between the first and latter half groups, and mediation analyses to compare the diagnostic and treatment methods between January 2010 and December 2019 (CODE BLUE-J Study).
Results: A total of 6575 patients with CDB were included.
Background And Aims: We sought to validate the British Society of Gastroenterology (BSG) guidelines for acute lower GI bleeding (ALGIB).
Methods: We analyzed 8956 patients with ALGIB in the Colonic Diverticular Bleeding Leaders Update Evidence From Multicenter Japanese Study (CODE BLUE-J) study and categorized them into 4 groups based on the BSG guidelines. Outcomes included 30-day rebleeding, 30-day mortality, blood transfusion, therapeutic intervention, and severe bleeding.
Article Synopsis
- The study examined the link between blood group O and the likelihood of rebleeding in patients with acute lower gastrointestinal bleeding (ALGIB).
- Out of 2336 patients analyzed, those with blood group O had higher rebleeding rates within 30 days (17.9%) and 1 year (21.9%) compared to non-O patients.
- Blood group O was found to be an independent risk factor for rebleeding, while rates of thrombosis and mortality were similar between groups.
Introduction: We investigated the factors associated with synchronous multiple early gastric cancers and determined their localization.
Methods: We analyzed 8,191 patients who underwent endoscopic submucosal dissection for early gastric cancers at 33 hospitals in Japan from November 2013 to October 2016. Background factors were compared between single-lesion (n = 7,221) and synchronous multi-lesion cases (n = 970) using univariate and multivariate analyses.
Article Synopsis
- The study analyzed 8,254 cases of patients with acute lower gastrointestinal bleeding to find key factors that predict mortality and create a reliable prediction tool.
- Researchers established the CACHEXIA score, which uses factors present at admission and management during hospitalization to assess the risk of death within 30 days and 1 year.
- The CACHEXIA score demonstrated high accuracy (ROC-AUC 0.93 for 30 days; C-index 0.88 for 1 year) with significant differentiation of mortality risk, indicating that patients with high scores need continuous monitoring after discharge.
