Outcome measures
Primary outcome
1. The number of patients and the number of lesions with early neoplasia detected with SVE and ETMI;
2. The number of patients with early neoplasia detected with targeted biopsies only with ETMI and SVE.
Secondary outcome
1. The sensitivity and positive predictive value (PPV) of HRE and AFI;
2. The reduction of false positive findings after NBI;
3. Negative predictive value of the combination of HRE and AFI and the reduction in false negative findings after.
Background summary
Endoscopic Trimodal Imaging is a new imaging device that incorperates high-resolution white light endoscopy with autofluorescence imaging and narrow band imaging. Our aim of this study is to compare ETMI with standard video endoscopy for the detection of early neoplastic lesions in Barrett's esophagus. In this study high-risk patients reffered for the work-up of high-grade dysplasia or early cancer will included. All prodedures will performed by expert endoscopists in this field in 4 tertiary referal centres for the endoscopic treatment of early Barrett's neoplasia. All patients will undergo two endoscopies (ETMI and SVE) perfromed by two different endoscopists with an interval of 6-12 weeks.
Study objective
ETMI improves the detection of early neoplasia in Barrett's esophagus.
Intervention
In this study we will compare diagnostic endoscopy techniques for the detection of early enoplasia in Barrett's esophagus. These techniques are standard video endoscopy (the current standard) and
Endoscopic Tri-Modal Imaging (ETMI). Patients will undergo two consecutive endoscopies in an interval of 8-12 weeks. One of the two aformentioned techniques will be randomly assigned to the first procedure, the second procedure will subsequently be performed with the other technique by a second endoscopist.
The primary outcome will be the number of lesions and patients with early neoplasia detected with standard video endoscopy and ETMI.

Inclusion criteria
1. Age > 18 years;
2. Prior diagnosis of BE defined as the presence of columnar lined epithelium in the tubular esophagus with specialised intestinal metaplasia on histological investigation;
3. Prior diagnosis of high-grade dysplasia or early cancer that was endoscopically inconspicuous according to the referring physician. Review of the pathology slides is not required for inclusion;
4. A minimum Barrett’s length of C>2M>2 or C<2M>4 according to the Prague C&M classification of the endoscopic appearance of BE;
4. Written informed consent.
Exclusion criteria
1. Presence of active erosive esophagitis > grade A according to the Los Angles classification of erosive esophagitis;
2. Description of an endoscopically visible suspicious lesion in the Barrett’s segment in the referring center;
3. Presence of conditions precluding histological sampling of the esophagus (e.g. esophageal varices, coagulation disorders, anticoagulant therapy);
4. At the first endoscopy: the presence of a type 0-I or type 0-III lesion or a lesion that, according to the discretion of the endoscopist, does not allow a delay in intervention for a period of 6 weeks (interval between the two cross-over endoscopies).
