Gastric endoscopic mucosal resection is challenging due to the slippery mucosa, abundant blood vessels, and the presence of mucus. We developed gel immersion endoscopy to secure the visual field, even in a blood-filled gastrointestinal lumen in 2016. Clear gel with appropriate viscosity, instead of water, can prevent rapid mixture with blood and facilitate identification of the culprit vessel.

In contrast to that for PPIs, the evidence concerning the safety of long-term potassium-competitive acid blocker use is scant. Vonoprazan (VPZ) is a representative potassium-competitive acid blocker released in Japan in 2015.

Article Synopsis
- This study compares the effectiveness of blue laser imaging (laser-BLI) and LED-blue light imaging (LED-BLI) for assessing colorectal polyps using a specific classification system (JNET).
- A total of 756 images from 63 lesions were analyzed by 12 endoscopists, resulting in a 92.5% agreement rate between the two imaging methods.
- The findings suggest that both imaging techniques provide very similar evaluations in terms of surface patterns, vessel patterns, and brightness, indicating that laser light could be a viable option for endoscopic examinations.
Background: Endoscopic balloon dilation (EBD) is an effective, minimally invasive treatment for Crohn's disease (CD) related intestinal strictures. However, restenosis frequently occurs and requires repetitive EBD or surgical resection. Since previous studies could not evaluate restenosis based on stricture diameter, factors affecting restenosis after EBD were unclear.

Little information is available on the seroprevalence of SARS-CoV-2 antibodies among healthcare workers (HCWs) in endoscopy units. Thus, the seroprevalence was examined in HCWs who do and do not participate in gastrointestinal endoscopy.
