Use of Goggle Balloon to Improve Cecal Intubation During Colonoscopy
Use of Goggle Balloon to Improve Cecal Intubation During Colonoscopy
This study aims to look if use of goggle balloon can help to complete colonoscopy in patients with very redundant colons.
About 5% of colonoscopies are technically difficult because the colon is elongated or redundant. There is an increased risk of the colonoscope not reaching the cecum in these cases. One solution to this is to try to keep the colon shorter by not insufflating it with gas. In order to achieve that, in these cases the investigators typically fill the colon with water, which does not distend the colon as much. Another technique, which can improve visualization, is to use a device called the goggle balloon. This is a small balloon filled with a few mL of water which fits over the end of the colonoscope and pushes the colonic mucosa away from the end of the scope so that the luminal direction can be visualized with minimal insufflation. In patients with normal colons, the goggle balloon can be used to insert the colonoscope to the cecum with virtually no air or water filling. We aim to study if the goggle balloon can be used to help complete the colonoscopy in patients with redundant colons.
