Examination of endoscopic intracanal observation with an ultrafine-diameter scope.

Objectives: The endoscopic channel can be damaged by instruments during use and cleaning, leading to contamination, infection, and increased repair costs. However, few devices are available to observe the inside of the endoscopic channel. This study employed an ultrafine-diameter scope to examine damage in the endoscopic channel.

Usefulness of a long hood for the detection of bleeding sites in colonic diverticular hemorrhage: A randomized controlled trial.

Background And Aim: The use of a hood at the tip of a colonoscope enables aspiration, inversion of the diverticulum, and observation of the inside of the diverticulum. In most previous studies, a short hood was used; however, observation of the diverticulum is often inadequate. Long food is promising by previous research, but it was a retrospective study using propensity matching and has some limitations.

Linked-color imaging with or without artificial intelligence for adenoma detection: a randomized trial.

Background: Adenoma detection rate (ADR) is an important indicator of colonoscopy quality and colorectal cancer incidence. Both linked-color imaging (LCI) with artificial intelligence (LCA) and LCI alone increase adenoma detection during colonoscopy, although it remains unclear whether one modality is superior. This study compared ADR between LCA and LCI alone, including according to endoscopists' experience (experts and trainees) and polyp size.

Nintedanib-associated enterocolitis with intractable diarrhea: a case report.

Revised idiopathic pulmonary fibrosis treatment guidelines were published in 2015, and nintedanib was conditionally recommended. Although diarrhea is reported to be a common major adverse event associated with nintedanib, there have been few reports on detailed endoscopic findings of nintedanib-associated enterocolitis. A 74-year-old woman was diagnosed with idiopathic pulmonary fibrosis 4 years ago in May.

Intussusception associated with pneumatosis cystoides intestinalis in a male adolescent: A case report.

Pneumatosis cystoides intestinalis is an uncommon disease that rarely causes intussusception. We report the case of a 16-year-old male patient with intermittent abdominal pain who was diagnosed with intussusception. The patient had no history of raw food ingestion, fever, diarrhea, or hematochezia.
