Visualization of the Colon Through Use of the Magnetic Flexible Endoscope (MFE)

The clinical practice at Vanderbilt University Medical Center (VUMC) is to perform the screening colonoscopic exam while the patient is sedated (Monitored Anesthesia Care administered by the VUMC out-of-OR Anesthesia team) with a legacy colonoscope (Olympus CF/PCF-H190L; Olympus America, Center Valley, PA, USA) to evaluate the patient's colon (via the rectum passed trans-anally with the intent of reaching the cecum). After the screening examination with the legacy colonoscope has been completed and the legacy colonoscope is removed from the patient, the sedation for the patient is stopped as per the standard of care. The patient will be monitored as per VUMC standard of care post-sedation monitoring protocol in the procedure room (post-sedation recovery phase). While the patient is in the post-sedation recovery phase in the procedure room, the MFE will be inserted trans-anally into the rectum and traverse the colon with the intent on reaching the cecum. No additional sedation is administered. After the cecum is visualized, the MFE will be removed from the patient. The patient will continue to be monitored as per VUMC standard of care post-procedure monitoring protocol in the procedure room. Once VUMC standard of care discharge parameters have been met, the patient will be discharged from the procedure area/VUMC as per standard of care. The investigators plan to enroll 5 healthy patients who are already scheduled to undergo their standard of care colonoscopic exam for age-appropriate colorectal cancer screening. The endpoints of the study are navigation of the colon, mucosal visibility, tolerability of the MFE traveling in the human colon, and endoscopist assessment.
