Clinical Outcomes Following Therapeutic Endoscopic Retrograde Cholangiopancreatography in Children With Pancreas Divisum.

ABSTRACT

OBJECTIVES: Pancreas divisum (PD) is a risk factor in children for the development of acute pancreatitis. Endoscopic retrograde cholangiopancreatography (ERCP) with minor papilla endoscopic sphincterotomy (mPES) may be of clinical benefit, however, the clinical outcomes from endotherapy remain unclear. We sought to review the outcomes and safety of therapeutic ERCP in children with PD. METHODS: We performed a retrospective chart of children with PD who underwent an ERCP between February 2012 and December 2018. Pertinent patient, clinical and procedure information was collected including procedure-related adverse events. A follow-up questionnaire of the parent was conducted to determine the clinical impact from endotherapy. RESULTS: Fifty-eight ERCPs were performed in 27 patients (14 boys; mean age 9.7 years, range 2-19) with PD. All patients underwent a successful mPES. A genetic variant was identified in 19/26 (73%) tested patients. Post-ERCP pancreatitis (PEP) was the only observed adverse event; 21% (12/58). Median follow-up interval from first ERCP intervention to questionnaire completion was 31.5 months (range 4--72 months). Of the 20 questionnaire responders, 13 reported clinical improvement from endotherapy. CONCLUSIONS: The majority of children from our PD cohort possessed at least 1 genetic variant. Most questionnaire responders had a favorable response to endotherapy. PEP rate was comparable with that of prior reports in adult patients.
