Safety and efficacy of endoscopic retrograde cholangiopancreatography in pediatric pancreatic and biliary disorders.

Abstract

There is sparse data from India on indications, technical success, safety and outcomes of endoscopic retrograde cholangiopancreatography (ERCP) using standard adult duodenoscope in the pediatric population. Retrospective analysis of prospectively maintained electronic endoscopy and clinical database was performed to identify pediatric patients (age ≤ 18years) who underwent ERCP between January 2017 and December 2022. Demographics and procedural details including indications, cholangio-pancreatogram findings, endotherapy type performed, technical and clinical success and complications were noted. As many as 150 pediatric patients were included of whom 88 had pancreatic (mean age-13.7years) and 62 had biliary disease (mean age- 14.9years). Common pancreatic ERCP indications were chronic pancreatitis (n = 45 [51.1%]), pancreatic duct disruption fistula (n = 21 [23.9%]) and recurrent acute pancreatitis (n = 16 [18.2%]). Among biliary indications were choledocholithiasis (n = 29 [46.8%]), benign bile duct strictures (n = 13 [21%]), bile duct injury/leak and biliary stent removal (n = 7 [11.3%]) , choledochal cyst (n = 5 [8.1%]) and pancreatic mass causing biliary compression (n = 1 [1.6%]). Technical success in pancreatic and biliary ERCP was 94.3% and 95.2%, respectively, and clinical success was 84.1% and 93.5%, respectively. Most common complications following pancreatic ERCPs were acute pancreatitis (n = 9 [10.2%]) (mild = 5, moderate = 4) patients and post sphincterotomy bleed in one (1.1%). Among biliary ERCPs, post ERCP pancreatitis was seen in (n = 3 [4.8%]) (mild = 2, moderate = 1). ERCP can be safely and effectively performed in children using standard duodenoscope. Chronic pancreatitis, choledocholithiasis and pancreatic divisum are common pediatric ERCP indications.
