Single-center experience of choledochoscopy in pediatric patients

Advances in the Treatment of Neonatal Biliary Disease

This article discusses current standard of care in neonatal biliary disease, particularly management of biliary atresia and choledochal cysts. It highlights surgical considerations, guidelines for adjuvant therapies, and promising therapeutic options that are under investigation.

Percutaneous Cholangioscopy for the Diagnosis and Management of Biliary Pathology in Pediatric Patients: A Single-Center Experience

Transhepatic percutaneous cholangioscopy (PC) can be used for the diagnosis and treatment of biliary pathology. It allows for direct visualization of the biliary system to identify pathologic changes, perform biopsies, and treat biliary obstruction. The effectiveness and safety of PC in adults have been established. However, the data on the use of PC in pediatric patients are limited. In this case series, the outcomes in 4 pediatric patients (3 girls; mean age, 4 [range, 1-8] years) who underwent 6 PC procedures were examined. Three out of the 6 (50%) PC procedures were performed for diagnostic visualization of the biliary tree and/or small intestine, whereas the remaining 3 (50%) were performed for the treatment of biliary obstruction causing chronic cholestasis. The technical and procedural success rate was 100%, and no complications were encountered during or 30 days after the procedure. This study supports the feasibility and safety of PC in pediatric patients for the management of biliary pathology.

Cholangioscopy in Children and Adolescents: Utilization, Outcomes, and Safety

BACKGROUND

Endoscopic retrograde cholangiopancreatography (ERCP) is increasingly utilized for management of biliary disorders in children and adolescents. Practice patterns surrounding cholangioscopy in pediatric patients, however, are largely uncharacterized.

METHODS

We retrospectively analyzed all ERCPs in which cholangioscopy was performed on patients 18 and under at our tertiary care children's hospital from 2015 to 2020 using our institution's paper and electronic medical record system. Patient demographics, procedure indications, interventions, and associated adverse events were analyzed.

RESULTS

Over the study period, 307 ERCPs were performed on 282 patients at our children's hospital. Cholangioscopy was performed in 36 procedures (11.7%) using the SpyGlass cholangioscope (Boston Scientific). Antibiotics to cover biliary organisms were administered to all patients precholangioscopy. Mean patient age was 13.6 years (range 7-18 years). The 2 most common indications for cholangioscopy included electrohydraulic lithotripsy for biliary stone disease and evaluation of biliary stricture (with incidental finding of biliary web in 2 patients and retained suture material in 2 patients). Adverse events were less prevalent in patients who underwent cholangioscopy relative to those who underwent ERCP. 0/36 (0%) developed post-ERCP pancreatitis, one patient had self-limited melena (possible self-limited postsphincterotomy bleeding). Patient care was enhanced by cholangioscopy in 30/36 (83.3%) of these patients.

CONCLUSIONS

These data attest to the safety and clinical utility of cholangioscopy in children and adolescents. Cholangioscopy was performed in just over 11% of pediatric patients who underwent ERCP at our academic medical center-rates similar to those reported in adult patients. The radiation-sparing nature of cholangioscopy, coupled with these data supporting its safety, make it particularly appealing for use in children. Further multi-institution evaluation of the utility, safety, and range of indications for cholangioscopy in other practice settings would be of great interest and help guide endoscopic care.
