Clinical application of capsule sponge testing in symptomatic reflux disease: a national prospective cohort study.

Background: Capsule sponge testing, using an oesophageal cell collection device with biomarkers, was implemented nationally across Scotland in 2020 for symptomatic reflux patients referred to secondary care for non-urgent endoscopy. The aim was to use capsule sponge testing as a triage tool to reduce pressures on the endoscopy service during COVID-19, focus endoscopy resources on those most likely to have pathology and streamline the patient pathway. This prospective cohort study presents the first real-world results and evaluates the clinical application of capsule sponge testing in symptomatic reflux disease based on endoscopic biopsy results.

Oesophageal cell collection device and biomarker testing to identify high-risk Barrett's patients requiring endoscopic investigation.

Background: Barrett's oesophagus surveillance places significant burden on endoscopy services yet is vital to detect early cancerous change. Oesophageal cell collection device (OCCD) testing was introduced across Scotland for Barrett's surveillance in response to the COVID-19 pandemic. This national pragmatic retrospective study presents the CytoSCOT programme results and evaluates whether OCCD testing is successfully identifying high-risk Barrett's patients requiring urgent endoscopy.

Tailoring follow-up endoscopy in patients with severe oesophagitis.

Objective: We aimed to investigate the clinical utility of follow-up oesophagogastroduodenoscopy (OGD2) in patients with severe oesophagitis (Los Angeles grades C or D) through evaluating the yield of Barrett's oesophagus (BO), cancer, dysplasia and strictures. Second, we aimed to determine if the Clinical Frailty Scale (CFS) may be used to identify patients to undergo OGD2s.

Design/method: Patients in NHS Lothian with an index OGD (OGD1) diagnosis of severe oesophagitis between 1 January 2014 and 31 December 2015 were identified.

National adoption of an esophageal cell collection device for Barrett's esophagus surveillance: impact on delay to investigation and pathological findings.

High quality Barrett's esophagus surveillance is crucial to detect early neoplastic changes. An esophageal cell collection device (OCCD) was introduced as a triage tool for Barrett's surveillance. This study aims to evaluate whether the Scottish OCCD program (CytoSCOT) has reduced delays to Barrett's surveillance, and whether delayed surveillance negatively impacts endoscopic pathology.
