Endoscopic retrograde cholangiopancreatography (ERCP) is an essential procedure that can be
complicated by post-ERCP pancreatitis (PEP). Indomethacin and ketorolac are two medications
used to prevent PEP. The main reason for this research study is to compare the effectiveness
these drugs at reducing rates of PEP. There have been no studies comparing the effectiveness
of these medications in preventing PEP in pediatric patients. You are being asked to take
part in this research study because you are scheduled to have an ERCP as part of your medical
care.
