Abstract
Background: Endoscopic sphincterotomy (EST) has been employed for the endoscopic treatment of common bile duct stones (CBDSs), and a high success rate of stone removal has been reported. However, EST is associated with the risk of bleeding, perforation, and sphincter of Oddi function disruption. To avoid these risks, endoscopic papillary balloon dilation (EPBD) is an option for CBDS. Sphincter of Oddi function preservation decreases long-term biliary infection and gallstone recurrence. EPBD may have advantages in children who require a long follow-up. However, there have been few reports on pediatric cases, particularly in infants.
Methods: From September 2017 to December 2023, we performed EPBD for four pediatric CBDSs. The patients were aged from 5 months to 8 years; including two infants aged 5 and 6 months. Furthermore, we reviewed the stone removal rate and complications of 545 ESTs performed at high-volume centers and 13 EPBD-reported cases in children with CBDSs.
Results: CBDSs of all patients who underwent EPBD in our institution were successfully removed. No bleeding or perforation was noted, and pancreatitis was observed in three patients. In an analysis of 545 ESTs in children, the stone removal rate was high, ranging from 83% to 100% (mean, 96%). The incidence of pancreatitis was 0%–9.6% (mean, 4.4%), and the grade of pancreatitis was almost mild. The bleeding frequency was 1.3%–5.4% (mean, 2.7%). According to the grade of bleeding, seven and four cases were mild (64%) and moderate (36%), respectively, Compared with adult cases who underwent EST, the frequency of pancreatitis and bleeding was almost similar in children.; however once bleeding occur, it has a higher risk of leading to blood transfusion in children. Stone removal by EPBD in children was 100% successful. All complications were pancreatitis, and its frequency was 46% (6/13 patients, including five mild cases and one moderate case), which is higher than that of EST and adult cases who underwent EPBD. In most children with pancreatitis, pancreatic enzyme levels returned to normal within 2–3 days following EPBD, and no severe cases caused by EPBD were reported.
Conclusions: CBDS removal by EPBD in children has a high success rate with very low risk of bleeding and perforation. Although pancreatitis frequently occurs, most cases are mild. Sphincter of Oddi function preservation by EPBD is expected to prevent long-term stone recurrence and biliary tract infection, and EPBD is considered an effective method for CBDS removal in children.
