Mid-to-long-term outcomes with image-guided placement of de novo low-profile gastrojejunostomy tubes in pediatric patients.

ABSTRACT

OBJECTIVE: De novo low-profile gastrojejunostomy (GJ) tubes are advantageous in children that require prolonged supplemental nutrition. However, few institutions place these devices at the time of initial feeding tube placement. We aim to build upon our previously published initial experience with this procedure to study mid-to-long-term outcomes of pediatric patients who have had de novo, image-guided, percutaneous low-profile GJ tube placement. METHODS: All de novo, image-guided, percutaneous, low-profile GJ tube placements at a single children's hospital were retrospectively reviewed between May 2014 and March 2021. Technical parameters, including fluoroscopy time, tube size, technical success, and complications were recorded. Clinical data, including age, indication, weight gain and transition to gastric/oral feeds were analyzed. RESULTS: 64 de novo low-profile GJ tubes were successfully placed in 65 patients (mean age 4.6 years, median 1, range 0.2-19; mean pre-procedural weight 16.8 kg, median 8.2, range 4.4-66.7). Average clinical follow-up 23.4 months (range 0.1-75, median 10.4). Average weight gain was 6.1 kg. Average increase in weight percentile was 7.3%. 19 (19/64; 29.7%) patients had conversion from GJ to G tube. 11 (11/64; 17.2%) patients had their enteric tube removed completely. There were 7 minor complications (7/65; 10.7%), most common being excessive skin irritation (6/7) and 9 major complications (9/65; 13.8%), most common being tube dislodgment within the first 30 days (6/9). CONCLUSIONS: These results further support that de novo, image-guided, percutaneous, low-profile GJ tube placement is technically feasible and efficacious in children requiring post-pyloric nutritional supplementation with a favorable safety profile.
