Primary gastrojejunostomy tube placement using laparoscopy with endoscopic assistance: A novel technique.

BACKGROUND: Gastrojejunostomy (GJ) tubes are commonly used to provide postpyloric enteral nutrition in pediatric patients who cannot tolerate gastric feeds. Most techniques depend on a preexisting gastrostomy tube (GT) site to convert to a gastrojejunostomy. Several minimally invasive techniques have been described; however, their risk profile varies widely. DESCRIPTION OF THE OPERATIVE TECHNIQUE: We present a technique for primary laparoscopic GJ tube placement that minimizes the risk of hollow viscus injury and the use of fluoroscopy through endoscopic assistance. RESULTS: Eleven GJ tubes were placed using this technique in patients ranging from 5 months to 17 years of age and weighing 6.3 to 46.0 kg. Endoscopy through the gastrostomy site allowed direct visualization of wire and tube placement. There were no intraoperative or postoperative complications within 30 days of operation. Use of fluoroscopy was limited with minimal total radiation exposure. CONCLUSION: The described technique of laparoscopic primary gastrojejunostomy tube placement with endoscopic assistance was associated with a low complication rate and minimal use of fluoroscopy. LEVEL OF EVIDENCE: IV.

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

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.
