Background: Metachronous multiple esophageal squamous cell carcinomas (ESCCs) may occur in some patients after endoscopic resection. Multiple dysplastic lesions in the esophagus increase risk of multiple squamous cell carcinomas (SCCs). Endoscopic imaging technology such as narrow band imaging (NBI), can detect early SCC.

Colonoscopy revealed a 15-mm-sized flat elevated lesion with a central depression in the sigmoid colon. Narrow-band imaging magnification revealed a Japan Narrow-Band Imaging Expert Team classification of type 2B, whereas crystal violet staining showed a mild to severely irregular type VI pit pattern.

Background And Aims: The multicenter, randomized, control trial was conducted to evaluate whether computer-aided diagnosis (CADx) improves the optical diagnosis of gastric neoplasia in non-expert endoscopists.
Methods: Patients undergoing endoscopy prior to endoscopic resection (ER) of gastric neoplasia or for surveillance after ER were randomized to the CADx-assisted and non-CADx-assisted groups. Endoscopy was performed by a non-expert endoscopist blinded to the patient information.

Background: Gel immersion endoscopy is a novel method that uses gel to enhance the visual field. This study aimed to analyze the efficacy of magnified endoscopy under gel immersion for optimal visualization and characterization of colorectal tumors.
Methods: We retrospectively examined 107 lesions observed with blue-laser/light imaging (BLI) or narrow-band imaging (NBI) between June 2022 and July 2023 using the Japan NBI Expert Team classification.
