Обзор

The investigators will conduct a large study in the primary care clinic to determine the feasibility of using tethered capsule endomicroscopy as a screening method for Barrett's esophagus (BE) in the primary care practice environment. The investigators are also determining the prevalence of Barrett's esophagus in a primary care practice cohort at MGH.

Подробное описание

The investigators have developed a tethered capsule OCT device intended as an inexpensive screening tool for BE. The capsule, which is attached to a thin, flexible tether, is reusable after being processed by a standard disinfection technique. Used without sedation, the capsule is swallowed by the participant and travels in the esophagus to the gastroesophageal junction (GEJ) via peristalsis. Cross-sectional microscopic OCT images of the entire esophagus are collected during transit. The total time needed for swallowing, imaging and retrieval does not exceed 10 minutes, with a total of 30 minutes for the procedure. The investigators have tested the feasibility and the tolerability of this new OCT screening technology in 250 procedures in healthy volunteers and participants with various esophageal diseases including BE. The procedure has been safe and well tolerated. High quality microscopic images of the esophagus have been obtained in 90% of the enrolled participants.

Вмешательства

  • Устройство Tethered Capsule Endomicroscopy
    Participants will be asked to swallow the TCE device. Participants may use mild numbing spray, and lubrication spray to help swallowing. Imaging will be conducted once the TCE device is past the pharynx. The TCE device will be advanced until the stomach and then slowly pull the TCE back up the esophagus. This may be repeated twice.

Первичные конечные точки

  • Subject Tolerability of Tethered Capsule Endomicroscopy Swallow [Срок оценки: During the single study visit (avg 30.mins), and before leaving, the participant will fill out the tolerability survey]
  • Prevalence of Barrett's esophagus within the single Primary Care Practice cohort. [Срок оценки: Imaging data is collected during the procedure, and analyzed within 1 year of collection.]

Критерии исключения
