Use of Endoscopic Retrograde Cholangiopancreatography in the Diagnosis and Management of Pediatric Pancreatic Injury

Background: ERCP is the gold standard for evaluating the integrity of the main pancreatic duct (MPD); however, ERCP is underutilized in evaluating MPD integrity in pediatric blunt pediatric injury. The primary aim of this study was to evaluate the discordance of cross-sectional imaging (CSI) and ERCP in children with suspected MPD injury.

Methods: A retrospective review of all patients age ≤18 years with CSI or clinical findings suggestive of MPD injury (MPDI) and ERCP was conducted at a level I pediatric trauma center from January 2009 to May 2023. Demographic and clinical data were collected. Pancreatic injury findings were compared between cross-sectional imaging and ERCP.

Results: An ERCP was performed in 28 patients with suspected MPDI with a mean age of 7 ± 4.5 years and weight of 25.0 ± 13.6 kg. Based on initial CSI, 23 patients had a suspected MPDI, and 5 had concern for MPDI based on clinical findings. ERCP differed from CSI findings in 39% of patients: 7 with CSI evidence of MPDI without injury on ERCP and 4 patients without imaging concern of MPDI but demonstrated injury on ERCP. Findings on ERCP guided surgical management in 71% (20/28) of patients due to location and completeness of MPDI. All patients without MPDI were managed nonoperatively.

Conclusion: Approximately 40% of patients had discordant findings between ERCP and CSI. ERCP can aide in surgical management decision making. All patients with a partial MPDI were managed with endoscopic therapy alone. ERCP should be considered when assessing a child with a suspected MPDI.

Level of evidence: Level III.

Type of study: Diagnostic Study.
