Official title
Pilot Study for Imaging the Lower Gastrointestinal Tract Using a Retro-TCE Capsule
Overview
The investigators have developed an inexpensive tool to take pictures in the lower GI tract without sedation and to look for signs of disease. The tool is a capsule, about the size of a fish oil or multi-vitamin supplement, attached to a string. The capsule and string are connected to a motor to allow the capsule to advance up the participant's lower GI tract. The capsule will be inserted into the participant's lower GI tract and advance upward via a slow spiral motion. The capsule is connected to an imaging system that saves and displays the images in real time.
Interventions
- Device Feasibility of using an OCT-based Retrograde Tethered Capsule Endomicroscope device to image the lower GI tract
30 participants will be enrolled in this study. All consented participants will receive the same intervention.
Primary outcome measures
- Ability of the R-TCE capsule to acquire quality images of the lower GI tract [Time frame: Imaging data is collected during the study procedure and analyzed within one year of collection.]
Secondary outcome measures (1)
- Tolerability of the R-TCE Capsule in an unsedated participant [Time frame: Day 1]
