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

Abstract

BackgroundERCP 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. MethodsA 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. ResultsAn 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. ConclusionApproximately 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 EvidenceDiagnostic Study Level III
