NvisionVLE™ Registry System Registry

Study Overview
=================
Brief Summary
-----------------
Prospective, multi-site registry with longitudinal follow up for patients undergoing EGD or endoscopy. The primary objective is to provide a collection of patient NvisionVLE™ procedural data for participating physicians, including, but not limited to, imaging data, clinical utility data, demographics, pathology, treatment, and surveillance.

Detailed Description
-----------------
This is a prospective, multi-site registry with longitudinal follow up for patients undergoing EGD or endoscopy. The primary objective is to provide a collection of patient NvisionVLE™ procedural data for participating physicians, including, but not limited to, imaging data, clinical utility data, demographics, pathology, treatment, and surveillance. Up to 1000 patients from up to 20 sites nationwide. There are no protocol defined follow up visits. Patients will undergo an initial baseline Volumetric Laser Endomicroscopy (VLE) procedure. A patient with a negative screening examination may not require additional screening endoscopies. For patients with established disease, further surveillance endoscopies will vary based on the extent of the disease (e.g. every 3 months, every 6 months, annual), which is based on the following American Society for Gastrointestinal Endoscopy (ASGE) guideline: the role of endoscopy in the surveillance of premalignant conditions of the upper GI tract. If patients have additional VLE procedures during the enrollment period, associated data will be collected.

-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percent of patients with endoscopically visible disease/ suspicious areas as determined by the physician | No protocol defined follow up visits. Patients will undergo an initial baseline Volumetric Laser Endomicroscopy (VLE) procedure. If patients have additional VLE procedures during the enrollment period, associated data will be collected. | Baseline | 
| Percent of patients with VLE visible abnormalities/ suspicious areas as determined by the physician | No protocol defined follow up visits. Patients will undergo an initial baseline VLE procedure. If patients have additional VLE procedures during the enrollment period, associated data will be collected. | Baseline | 
| Percent of patients with histologically confirmed disease and a breakdown of diseases observed | No protocol defined follow up visits. Patients will undergo an initial baseline VLE procedure. If patients have additional VLE procedures during the enrollment period, associated data will be collected. | Baseline | 
| Percent of treated patients with endoscopic and VLE identified areas of retained or persistent abnormalities at the first endoscopic evaluation after treatment | No protocol defined follow up visits. Patients will undergo an initial baseline VLE procedure. If patients have additional VLE procedures during the enrollment period, associated data will be collected. | Baseline | 
| Percent of treated patients undergoing surveillance with endoscopic and VLE areas of recurrent abnormality diagnosed by histology as disease | No protocol defined follow up visits. Patients will undergo an initial baseline VLE procedure. If patients have additional VLE procedures during the enrollment period, associated data will be collected. | Baseline | 
| Percent of patients with abnormalities/ suspicious areas identified by the physician as subsquamous visualized on VLE and not seen on endoscopy | No protocol defined follow up visits. Patients will undergo an initial baseline VLE procedure. If patients have additional VLE procedures during the enrollment period, associated data will be collected. | Baseline |
