Background And Aims: PuraStat (3-D Matrix, Tokyo, Japan) is an absorbent localized hemostatic agent that uses self-assembling peptide technology. In this multicenter pilot study, we evaluated the efficacy and safety of endoscopic hemostasis using PuraStat in patients with colonic diverticular bleeding (CDB).
Methods: This study involved patients who had CDB with stigmata of recent hemorrhage (SRH) and underwent endoscopic hemostasis with PuraStat monotherapy or combination therapy comprising PuraStat with endoscopic band ligation (EBL) or clipping (group A).
Article Synopsis
- The study compares two bowel cleansing methods for colonoscopy preparation: Sodium picosulfate/magnesium citrate (SP/MC) and polyethylene glycol (PEG) with ascorbic acid, with a focus on patient acceptability and effectiveness.
- The trial includes 540 participants aged 40-69 and evaluates bowel cleansing quality using the Boston Bowel Preparation Scale, along with other factors like patient satisfaction and detection of polyps.
- Researchers aim to demonstrate that SP/MC is not only more acceptable due to its smaller dosage and better taste but also as effective as PEG for ensuring thorough bowel cleansing in outpatient settings.
Objective: This study was performed to evaluate whether the use of CAD EYE (Fujifilm, Tokyo, Japan) for colonoscopy improves colonoscopy quality in gastroenterology trainees.
Methods: The patients in this multicenter randomized controlled trial were divided into Group A (observation using CAD EYE) and Group B (standard observation). Six trainees performed colonoscopies using a back-to-back method in pairs with gastroenterology experts.
The virtual scale endoscope (VSE) is a new endoscope that helps estimate the size of neoplasms in the gastrointestinal tract. We compared the accuracy of polyp size estimation by VSE with that of visual estimation. A dual center prospective study was conducted in two Japanese academic endoscopy units.

Ileocolonoscopy revealed increased capillary growth, fine granular mucosa, and longitudinal mucosal tears mainly in the left side of the colon. A bioptic examination revealed thickened subepithelial collagen bands, thus confirming the diagnosis of collagenous colitis.
