IDDF2018-ABS-0131 Usefulness of castor oil for bowel preparation for colon capsule endoscopy in the patients on dialysis

BackgroundColon capsule endoscopy was approved for reimbursement under the national health insurance system of Japan in 2014. For this reason, detailed examination by capsule endoscope appears as useful. However, the capsule excretion rate after recommended bowel preparation reportedly ranges 70% to 90%, and administration of boosters is also necessary. For dialysis patients, liquid loading is a problem. In this study, we evaluated the efficacy of bowel preparation with castor oil for improving the capsule excretion rate. In 25 patients both capsule transit time and duration of colon capsule endoscopy were shorted. The results were presented and briefly discussed in the report.MethodsThis study included patients who underwent colon capsule endoscopy at Masuko Memorial Hospital since March 2016. Colon Capsule endoscopy was performed with Pillcam Colon Capsule (Medtronic, Minneapolis, MN, USA). The recommended protocol for bowel preparation was modified (with the administration of castor oil), and success rate of completing entire colon observation was compared. The dose of castor oil was 6=at each time point. This study was approved by the ethics committee of my hospital, while we obtained written consent from the participants after providing a thorough explanation of the contents and methods of this study.ResultsThe success rate of completing entire colon observation was 24 patients were 35 (96%) in the study. The maximal water intake of the fluid volume is 390=. The average consumption in patients on dialysis was an average of median 317=, and the patients of the smallest water intake had 200=two patients. A utility is very high for the patients on dialysis with moisture restrictions.ConclusionsAlthough the number of patients receiving bowel preparation with castor oil was small, entire colon observation was successful in dialysis patients. Thus, castor oil appears to be useful for bowel preparation for colon capsule endoscopy.
