ABSTRACT
Background:
Gastric variceal (GV) bleeding is among the most morbid sequelae of portal hypertension, with mortality ranging from 30% to 50%. Pediatric data focused on endoscopic approaches to management are needed. The present study represents the first pediatric case series of endoscopic ultrasound (EUS)-guided coil placement within feeding vessels as monotherapy for management of GV bleeding.
Methods:
Using our prospectively maintained endoscopy database, we identified patients 18 years and younger who underwent EUS-guided coil placement for management of GV bleeding from 2008 to 2018. Demographics, indication, procedural interventions/findings, and available clinical outcomes data were analyzed.
Results:
Twelve patients (median age 15, range 11–18 years) underwent EUS-guided coil placement for GV bleeding. All had portal hypertension, with EV in 58.3% and prior GV bleeding with attempted endoscopic management in 75%. Coil placement was accomplished using a linear echoendoscope and a 19-gauge needle. A mean of 2.75 (± 0.43) coils were placed in each patient (4, 6, 8, and 10 mm Nester Embolization Coils, Cook Medical, Bloomington, Indiana, USA). Immediate hemostasis was achieved in all patients, and 25% of patients developed recurrent gastric varices at a median of 5.5 months following the initial EUS-guided coil placement (range 4–6 months) over the median 12 month follow-up period.
Conclusions:
The present study establishes the feasibility and efficacy of EUS-guided coil placement as monotherapy for GV bleeding in children and adolescents. The technique was technically successful, with primary hemostasis achieved in all patients. EUS-guided embolization with coils may represent an alternative to current approaches for management of highly morbid GV bleeding.
