¹Note a portion of patients had multiple indications for endoscopic retrograde cholangiopancreatography (ERCP).

²Other indications for ERCP include: Deranged liver function tests, abdominal pain and bile leak follow up.

ERCP: Endoscopic retrograde cholangiopancreatography; CT: Computed tomography.
