Pulling instead of pushing: A case report of gastrostomy-assisted pull technique as an alternative method for endoluminal sponge placement in EVAC therapy.

ABSTRACT

Endoscopic vacuum-assisted therapy offers an easier and safer alternative to thoracic surgery, self-expanding stents, or esophageal clips and has been shown to be a promising technique for management of pediatric esophageal perforations. In this report, we present a novel application of a percutaneous endoscopic gastrostomy-assisted pull technique, wherein a preexisting gastrostomy is reaccessed to allow safe placement of the vacuum sponge with a more comfortable and effective endoscopic vacuum-assisted closure therapy compared to transnasal or transoral options. A 7-year-old male with a history of type C esophageal atresia with distal tracheoesophageal fistula complicated by leak and refractory esophageal stricture, severe tracheomalacia, and prior esophageal stricture resection presented for posterior tracheoplasty and tracheopexy complicated by esophageal perforation. A preexisting gastrostomy site was re-accessed to allow for a novel approach for endoluminal sponge placement in endoscopic vacuum-assisted closure (EVAC) therapy by gastrostomy-assisted pull technique. The patient had appropriate healing without further leak 1 month after repair. This case highlights the use of EVAC as a minimally invasive option for repair of esophageal perforation using a pull-through method at the percutaneous endoscopic gastrostomy tube site as gastric access. This method may improve control of placement and reduce sponge migration, reduce intraluminal distance of sponge placement, and reduce morbidity by avoiding thoracotomy.
