This study examines the role of trainee involvement with pediatric endoscopic retrograde cholangiopancreatography (ERCP) and whether it affects the procedure's success, post-procedural adverse outcomes, and duration. A secondary analysis of the Pediatric ERCP Database Initiative, an international database, was performed. Consecutive ERCPs on children <19 years of age from 18 centers were entered prospectively into the database.

Previous studies have demonstrated the safety of performing endoscopic retrograde cholangiopancreatography (ERCP) in the pediatric population; however, few have addressed the outcomes of children undergoing ERCP during acute pancreatitis (AP). We hypothesize that ERCP performed in the setting of AP can be executed with similar technical success and adverse event profiles to those in pediatric patients without pancreatitis. Using the Pediatric ERCP Database Initiative, a multi-national and multi-institutional prospectively collected dataset, we analyzed 1124 ERCPs.

Article Synopsis
  • - The study aimed to investigate differences in clinical characteristics and treatment of pediatric acute recurrent pancreatitis (ARP) and chronic pancreatitis (CP) across various INSPPIRE locations, comparing US regions to non-US sites.
  • - Data from 479 subjects revealed geographic variances: the South had a higher prevalence of Hispanic ethnicity and gallstones, while non-US patients had lower rates of CP and longer times from initial diagnosis.
  • - The findings indicate significant disparities in management practices and disease burden across regions, with US sites utilizing more advanced treatments like ERCP and CT scans compared to non-US sites, warranting further research into these variations.

Objectives: Adults with chronic pancreatitis (CP) have a high risk for developing pancreatogenic diabetes mellitus (DM), but little is known regarding potential risk factors for DM in children with acute recurrent pancreatitis (ARP) or CP. We compared demographic and clinical features of children with ARP or CP, with and without DM, in the INternational Study Group of Pediatric Pancreatitis: In Search for a CuRE (INSPPIRE) registry.

Methods: We reviewed the INSPPIRE database for the presence or absence of physician-diagnosed DM in 397 children, excluding those with total pancreatectomy with islet autotransplantation, enrolled from August 2012 to August 2017.

Objective: Functional pancreatic sphincter dysfunction (FPSD), previously characterized as pancreatic sphincter of Oddi dysfunction, is a rarely described cause of pancreatitis. Most studies are reported in adults with alcohol or smoking as confounders, which are uncommon risk factors in children. There are no tests to reliably diagnose FPSD in pediatrics and it is unclear to what degree this disorder contributes to childhood pancreatitis.
