Background Percutaneous endoscopic gastrostomy is commonly used for enteral nutritional access, but gastrocutaneous fistulae (GCF) may persist after tube removal, posing clinical challenges. The use of endoscopic closure devices, including over-the-scope clips (OTSC), has shown promise in managing non-healing fistulae, although data in the pediatric population are limited. Methods A retrospective multicenter study analyzed pediatric patients who underwent GCF closure following gastrostomy tube removal. Data from seven centers across multiple countries were collected, including patient demographics, procedural details, complications, and outcomes. Closure techniques were compared between OTSC and surgical closure. Results Of 67 pediatric patients included, 21 underwent OTSC closure and 46 had surgical closure. Surgical closure demonstrated a higher success rate (100%) compared to OTSC closure (61.9%, P < 0.001). While procedural duration was shorter for OTSC closure (25 vs. 40 min, P = 0.002), complications, and scar quality were comparable between techniques. A subsequent sub-analysis did not reveal differences based on center experience. Conclusion OTSC closure is feasible and safe in pediatric patients, but surgical closure remains superior in achieving sustained GCF closure, although OTSC offers benefits, such as shorter procedural duration, potentially reducing the duration of general anesthesia exposure. Non-operative approaches, including OTSC, may be a valuable alternative to surgical closure.
