Non-Endoscopic Detection of Barrett's Esophagus Using Methylation Biomarkers on EndoSign® Cell Collection Device Samples

Efficacy and Safety of HYbrid Argon Plasma Coagulation Technique in Patients With Barrett's Esophagus-Related Dysplasia

Detection of Barrett s Esophagus in Patients Without GERD Symptoms

This study will investigate whether using EsoCheck/EsoGuard(EC/EG) can detect BE in individuals at risk for BE who are currently not being detected and are not undergoing routine esophago-gastro-duodenoscopy (EGD) BE can only be diagnosed by performing upper endoscopy. Up to 500 adults who have risk factors for BE but do not have chronic heartburn or regurgitation will be enrolled in this study. This will include the EsoCheck/EsoGuard determination along with the upper endoscopy for qualifying EsoGuard negative subjects

Application of hybridAPC in the Treatment of Barrett

After thermal ablation of Barrett's esophagus, stricture formation is reported in 5 to over 10% of patients. Submucosal fluid injection prior to ablation may lower the risk of stricture formation. The new technique of HybridAPC which combines submucosal injection with APC is considered to reduce the complication.

Pilot Study for TCE Imaging of the Esophagus Using an OFDI Capsule With a Compact Imaging System

Ten healthy volunteer subjects and ten volunteers with a previous diagnosis of Barrett's Esophagus (BE) will be enrolled in the study. The capsule is attached to a string-like tether which allows the operator to control as well as navigate the capsule as it progresses down the esophagus using peristalsis. Images of the esophagus will be acquired in real time to be analyzed later.

Australian Barrett's Cohort With Dysplasia and Early Cancer Study

CBAS180 De-escalation Study

Cryoballoon ablation is a relatively new ablation technique for the treatment of dysplastic Barrett's esophagus (BE). Previous studies with this technique have shown that treatment is safe and effective. When compared to other ablation techniques, cryoballon ablation has several potential advantages, including less pain and less complications such as stricture formation after treatment. Recently, a cryoballoon ablation system has become available which enables treatment of larger esophageal surfaces. Although a recent clinical study with this new device has shown promising results, the lowest possible dose that optimally balances safety and efficacy is still unknown. This study is a multicenter, prospective, intervention study consisting of two phases: the treatment phase and the follow-up phase. During the treatment phase, patients will undergo an upper endoscopy during which CBAS180 treatment will be performed. Treatment consists of two CBAS180 applications, starting just below the gastroesophageal junction (GEJ), resulting in a circumferential ablation of 3cm in length. During the treatment phase, two doses will be tested consecutively starting with the lowest dose (i.e. 1.2mm/sec). For each dose a total of 25 patients will be included. An interim analysis will be performed after treatment of the first 25 patients with the lowest dose of 1.2mm/sec, before proceeding to treatment of the additional 25 patients with a higher dose of 1.1mm/sec. The follow-up phase starts after CBAS180 treatment and ends after first follow-up endoscopy at 10 weeks (±2 weeks) after treatment. Therefore, the study duration will be approximately 3 months for each individual patient. The investigators expect to report the primary outcome for all participating patients within 2 years.

Navicam for Detection of Barrett's Esophagus

Accuracy, Yield and Clinical Impact of a Low-Cost HRME in the Early Diagnosis of Esophageal Adenocarcinoma

Primary outcomes: - the diagnostic yield (defined as the proportion of mucosal biopsy samples with neoplasia) of HRME with directed biopsy - compared to standard white-light endoscopy with 4-quadrant random biopsy (WL) for the diagnosis of BE-associated neoplasia in flat mucosa as well as mucosal lesions - the clinical impact of HRME on the diagnosis and endoscopic surveillance of BE- associated neoplasia - does HRME alter the decision to obtain a mucosal biopsy or perform endoscopic mucosal resection (EMR) - the total number of total mucosal biopsies taken per procedure; does HRME alter the number of biopsies necessary? Secondary outcomes: - sensitivity, specificity, positive predictive value, and negative predictive value of HRME for the in-vivo diagnosis of neoplasia in a routine surveillance population of patients with BE (using histopathologic diagnosis of mucosal biopsies as the reference standard) - the total procedure time for imaging and mucosal biopsy acquisition of HRME - compared with WL, stratified by length of BE (< 3 cm and > 3cm)

TREAT-BE Study (Treatment with Resection and Endoscopic Ablation Techniques for Barrett's Esophagus)

Patients will be enrolled in this study at the participating centers when evaluated in gastro-intestinal (GI) clinics and endoscopy suites. Initial evaluation of patients will include collection of data on demographics, assessment of risk factors such as smoking, metabolic syndrome, family history and detailed medication history, and past surgical history. All patients will be complete questionnaires regarding Gastroesophageal Reflux Disease (GERD) symptoms, GERD related quality of life (QOL) and overall health related QOL. Details of all previous endoscopic and surgical evaluation along with histopathology data will be documented. Patients undergoing endoscopic evaluation at the participating centers will have their endoscopic and histopathology results documented. This will include data collection regarding use of advanced imaging techniques, details regarding tissue acquisition, EET and adverse events. Patients undergoing esophagectomy will have surgical details documented along with complications related to surgery. Similarly, details regarding chemoradiation treatments will be documented .
