Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.
