Artificial intelligence (AI)-assisted colonoscopy systems with contact microscopy capabilities have been reported previously; however, no studies regarding the clinical use of a commercially available system in patients ulcerative colitis (UC) reported. In this study, diagnostic performance an AI-assisted ultra-magnifying for histological healing was compared that conventional light non-magnifying endoscopic evaluation UC.

Background: Small bowel (SB) lesions in quiescent Crohn’s disease (CD) are sometimes not identified by clinical activity or existing markers. We investigated the usefulness of a novel biomarker, leucine-rich α2-glycoprotein (LRG), for screening presence SB ulcerative detected small-bowel capsule endoscopy (SBCE). Methods: examined patients with Disease Activity Index (CDAI) value < 150 and C-reactive protein (CRP) 0.5 mg/dL colonic CD. The (≥0.5 cm) was grouped SBCE results, we then compared...

Tofacitinib (TOF), a Janus kinase inhibitor, has emerged as an innovative treatment option for patients with moderate-to-severe ulcerative colitis (UC). However, the clinical course of who achieve induction and maintain remission followed by TOF tapering or withdrawal is unclear. We investigated efficacy after in real-world practice. Thirty-two treated 20 mg/day UC relapse between October 2018 August 2023 were included this single-center, retrospective observational study. Disease activity...

Coronavirus disease 2019 (COVID-19), caused by infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is now a pandemic. Although several treatment guidelines have been proposed for patients who both inflammatory bowel and COVID-19, immunosuppressive therapy essentially not recommended, the options are limited. Even in COVID-19 pandemic, adjuvant adsorptive granulocyte monocyte apheresis may safely bring ulcerative colitis (UC) into remission removing activated myeloid...

We treated a 39-year-old Japanese man who was admitted for an abdominal mass. He had neurofibroma-like skin lesions since childhood. Computed tomography and endoscopic ultrasound results were consistent with tumor in the small intestine. Although undetectable by single-balloon endoscopy, patient’s background imaging led us to suspect gastrointestinal stromal (GIST). also met diagnostic criteria neurofibroma type 1 (NF1). performed surgical removal of tumor, biopsy definitive diagnosis GIST....
