Abstract null null Aims null To compare polyethylene glycol (PEG) high-volume to PEG low-volume with bisacodyl split-dosing regimens. null null null Methods null Adult outpatients in 10 Canadian tertiary hospitals were randomized, stratified by morning or afternoon colonoscopy, to PEG high-volume split-dose (2+2L) (High-SD) or low volume (1L+1L) + bisacodyl (15mg) (Low-SD) with a second randomization to liquid or low-residue diets. The primary endpoint, using non-inferiority hypothesis testing w...

Background Clinical implementation of the resect-and-discard strategy has been difficult because optical diagnosis is highly operator dependent. This prospective study aimed to evaluate a resect-and-discard strategy that is not operator dependent. null null null null Methods The study evaluated a resect-and-discard strategy that uses the anatomical polyp location to classify colonic polyps into non-neoplastic or low risk neoplastic. All rectosigmoid diminutive polyps were considered hyperplastic...

ABSTRACT Background & Aims Endoscopic submucosal dissection (ESD) is a widely accepted treatment option for superficial gastric neoplasia in Asia, but there are few data on outcomes of gastric ESD from North America. We aimed to evaluate the safety and efficacy of gastric ESD in North America. Methods We analyzed data from 347 patients who underwent gastric ESD at 25 centers, from 2010 through 2019. We collected data on patient demographics, lesion characteristics, procedure details and related ...

Background and study aims A novel endoscopic optical diagnosis classification system (SIMPLE) has recently been developed. This study aimed to evaluate the SIMPLE classification in a clinical cohort. Patients and methods All diminutive and small colorectal polyps found in a cohort of individuals undergoing screening, diagnostic, or surveillance colonoscopies underwent optical diagnosis using image-enhanced endoscopy (IEE) and the SIMPLE classification. The primary outcome was the agreement of su...

Background and Aims Optical polyp diagnosis using image-enhanced endoscopy (IEE) allows for real-time histology prediction of colorectal polyps. The aim of this study was to evaluate a recently introduced IEE modality (Optivista [OV]; Pentax Medical, Tokyo, Japan) in a randomized controlled trial. Methods In a prospective cohort of subjects (ages 45-80 years) undergoing elective screening, surveillance, or diagnostic colonoscopy, all colorectal polyps between 1 and 5 mm underwent IEE assessment....

Background: Standard colonoscopy practice requires removal and histological characterization of almost all small (<10 mm) and diminutive (≤5 mm) colorectal polyps found. The aim of this study was to test a simplified polyp-based resect and discard (PBRD) strategy that assigns surveillance intervals based only on size and number of small and diminutive polyps, without the need for pathology. Methods: A post hoc analysis was performed on patients enrolled in a prospective colonoscopy study. The pr...
