Interventions

None listed

Eligibility

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: - Age > 18 * 80 years; - BO with a minimal circumferential length of 2 cm; - BO without dysplasia (NDBO) and patients with BO referred for endoscopic work-up of HGIN or EC; - Signed informed consent.

Exclusion criteria

Exclusion criteria: - Prior history of surgical or endoscopic treatment for oesophageal neoplasia; - Presence of erosive oesophagitis (Los Angeles classification *B); - Inability to obtain biopsies (e.g. due to anticoagulation, coagulation disorders, varices); - Unable to provide signed informed consent.

Design outcomes

Primary

Measure	Time frame
Phase 1 will be used to develop a tissue recognition algorithm by correlating the measured fluorescence spectra to the histology of the corresponding tissue. In phase 2 the WavSTAT optical biopsy will be validated and assessed for the following outcome parameters: 1. sensitivity and specificity of WavSTAT for the detection of early Barrett neoplasia (HGIN/EC) 2. additional value of WavSTAT to standard inspection with WLE, compared to inspection with WLE alone for the detection of early Barrett neoplasia (HGIN/EC).	—
