Does endoscopy of difficult to catheterize channels spare some patients from formal open revision?

Approximately half of our patients did not require a formal channel revision after endoscopic management. We did not identify any specific risk factors for subsequent formal revision of a CCC. We recommend performing at least one endoscopic evaluation for those with difficulty catheterizing prior to proceeding with formal open revision.Table.
