RISK FACTORS FOR RECURRENT BILE DUCT STONES AFTER ENDOSCOPIC PAPILLARY BALLOON DILATION: LONG‐TERM FOLLOW‐UP STUDY

Abstract

Approximately 7% of patients develop stone recurrence after EPBD; however, retreatment with endoscopic retrograde cholangiopancreatography is effective. Careful follow up is necessary in patients with dilated bile duct or previous cholecystectomy. IDUS is useful for reducing stone recurrence after EPBD.
