A more relaxing colonoscopy?
A preliminary study suggests that patients who get virtual colonoscopies, which are alternatives to regular colonoscopies, might avoid the unpleasant task of bowel-cleansing with laxatives beforehand.
Colon cancer is a challenging disease, and colonoscopy screening enables doctors to identify, and remove, precancerous polyps.
In a virtual colonoscopy, doctors use a CT scan to inspect the intestines for signs of colon cancer.
The scan uses a contrast agent, which is added to low-fibre meals and snacks for two days before the procedure.
No laxative needed, and a much happier outcome for the patient.
