Clinical Trial Summary

The goal of this research is to determine (1) the feasibility of tethered capsule OCT esophageal imaging in the Parkinson's Disease population; (2) the morphologic changes in the enteric nervous system of the esophagus in patients with Parkinson's disease.


Clinical Trial Description

The purpose of this study is to establish the esophageal pathology findings as imaged with tethered capsule microscopy in subjects with Parkinson Disease. Images from patients with Parkinson disease will be compared to our previously obtained images in healthy subjects to establish the spectrum of esophageal pathologies occurring in patients with Parkinson disease by OCT imaging. In the case of imaging internal luminal organs, like the esophagus, OCT light is delivered via a long catheter. We have developed a new technique termed Tethered Capsule Endomicroscopy (TCE). TCE involves swallowing a tethered capsule that acquires cross-sectional microscopic images of the entire esophagus as it traverses the luminal organ via peristalsis or is pulled up towards the mouth using tether. The catheter is connected to the imaging system, and the side-viewing optical beam rotates either proximally by a motorized rotary joint or distally by a micro-motor, effectuating circular scanning of the lumen wall. Three-dimensional OCT of the entire length of the lumen can be acquired by simultaneous rotation and translation of the focused OCT beam creating a helical pattern. ;
