The aim of this study was to develop and prospectively validate a simple endoscopic score of disease activity for dogs with inflammatory bowel disease (IBD). Archived endoscopic still images and video recordings of gastric, duodenal, and colonic endoscopic examinations were displayed to novice and experienced endoscopists for assessment of inflammatory activity using established descriptions. The mucosal appearances evaluated were normal tissue, erosions, friability, increased granularity, lymphangiectasia (duodenum), and mass (colon). Fleiss and Cohen's Kappa statistics were used to estimate the inter-observer agreement of the index. For duodenal assessment, there were statistically significant (P <0.05) differences in inter-observer agreement, with experienced endoscopists performing better than novice endoscopists in the accurate identification of mucosal appearance of the duodenum. In contrast, there was no significant difference between novice and experienced endoscopists in their interpretation of gastric (P = 0.10) and colonic (P = 1.0) mucosal appearances. Validation studies using endoscopic video clips to assess the same endoscopic parameters by quantitative (lesion number and severity) and qualitative (presence of mucosal lesions) methods showed moderate-to-substantial agreement between experienced endoscopists. Based on the observations that the quantitative and qualitative scores of mucosal appearances are virtually identical, and that qualitative assessment was performed more quickly and objectively than quantitative assessment, we propose a simple endoscopic activity score based on qualitative criteria alone in dogs with inflammatory bowel disease.

Importance: High-quality colonoscopy reduces the risks of colorectal cancer by increasing the adenoma detection rate. Routine use of an automatic quality control system (AQCS) to assist in colorectal adenoma detection should be considered.
Objective: To evaluate the effect of an AQCS on the adenoma detection rate among colonoscopists who were moderate- and low-level detectors during routine colonoscopy.

Background: Despite the availability of several biologics for ulcerative colitis (UC), there remains a critical need to identify first-line treatment biologics. The superiority of infliximab (IFX) over vedolizumab (VED) and ustekinumab (UST) was evaluated as initial UC treatments in patients with biologic-naïve UC.
Methods: This multicenter, randomized control trial was conducted across 20 Japanese medical institutions.

Background: The aberrant expression of α defensin 5 (DEFA5) protein in colonic inflammatory bowel diseases (IBDs) underlies the distinct pathogenesis of Crohn's colitis (CC). It can serve as a biomarker for differentiating CC from Ulcerative colitis (UC), particularly in Indeterminate colitis (IC) cases into UC and CC. We evaluated the specificity of commercially available anti-DEFA5 antibodies, emphasizing the need to further validate their appropriateness for a given application and highlighting the necessity for novel antibodies.

There are national and international guidelines and developments for the surgery of chronic inflammatory bowel disease (IBD) that contribute to better patient care. Important recommendations include increasingly individualized and minimally invasive approaches with the integration of new technologies. The indication for abdominal surgery remains tied to specialization, not least in order to continue to be able to assess the importance of sequential treatment and multimodality in improving surgical results and minimizing risks.

Background: Historically, randomized controlled trials (RCTs) have been criticized for being poorly generalizable to patients with ulcerative colitis (UC) evaluated in routine care. We aimed to evaluate the proportion of patients with UC starting an advanced therapy who would be eligible to participate in phase 3 registrational UC RCTs.
Methods: We conducted a retrospective cohort analysis of UC patients starting vedolizumab, ustekinumab, or tofacitinib at 2 IBD clinics at the University of Calgary.
