Usefulness of Castor Oil for Bowel Preparation for Colon Capsule Endoscopy in the Patients on Dialysis

Since Colon capsule endoscopy (CCE) was approved for reimbursement under the national health insurance system of Japan in January 2014. Dialysis patients are potentially susceptible to bleeding because of the fragile intestine, impaired platelet function, or oral administration of nonsteroidal antiinflammatory drugs (NSAIDs) or anticoagulants. Increasing experience with CCE different bowel preparation regimens have been used with variable results. The patient on dialysis has moisture restrictions. We experienced the case of the half a dose of the previous protocol by a method using the castor oil. In this study, we evaluated the efficacy of bowel preparation with castor oil for improving the capsule excretion rate. In 23 of 24 (95.8%) patients capsule transit time and duration of capsule endoscopy were shortened. The results are presented and briefly discussed in this report.
