Gastrojejunal tube placement through an established gastrostomy via an endoscopic transgastric approach in a pediatric population

Abstract

Background and aims: Gastrojejunal feeding tubes (GJTs) are typically converted from gastrostomy feeding tubes by interventional radiology in many pediatric centers to provide both postpyloric feeding and gastric decompression. Endoscopic transgastric GJT placement via an established gastric stoma can be performed without sedation and with minimal fluoroscopy but is relatively new in pediatrics with limited description. This study analyzed the success rate, adverse events, and technical issues associated with endoscopic GJT placement via a transgastric approach in pediatric patients at a large children's hospital.

Methods: We retrospectively reviewed endoscopic GJT placements in pediatric patients performed over a 16-month period at the Children's Hospital of New York-Presbyterian, Columbia University Medical Center. Indication for GJT placement, patient demographic characteristics and medical history, use of sedation, fluoroscopy time, and procedural and postprocedural adverse events were assessed.

Results: A total of 47 GJT placements were performed, all successful, in a patient cohort with a mean age of 8 years. The mean fluoroscopy time was 10 seconds, and sedation was used in 30% of placements. In 8 patients who had undergone GJT placement by endoscopy and interventional radiology, the fluoroscopy time was significantly reduced by using the endoscopic method (10 seconds vs 299 seconds, P = .001).

Conclusions: Endoscopic transgastric GJT placement via an established gastrostomy with fluoroscopic confirmation can be safely performed by pediatric gastroenterologists without sedation and with minimal radiation exposure.
