Colon capsule endoscopy was approved for reimbursement under the national health insurance system of Japan in 2014.
However, the capsule excretion rate after recommended bowel preparation reportedly ranges from 70% to 90%, and administration of boosters is also necessary. The caster oil-based booster had an emission rate of 97%, but required a total water content of 3L. Considering whether it is possible to popularize colon capsule endoscopy by reducing the amount of water, including dialysis patients with water restrictions, we will consider whether the capsule discharge rate can be improved by combining new laxatives.
