Endoscopic ultrasound-guided coil deployment with sclerotherapy for isolated gastric varices: Case series of feasibility, safety, and long-term follow-up.

The purpose of the present study is to report our experience of endoscopic ultrasound-guided coil deployment with sclerotherapy (EUS-CS) for isolated gastric varices (IGV) through a case series. Eight consecutive patients who had risky IGV were prospectively enrolled. EUS-CS was performed according to the following procedures: (i) several coils were first deployed in the IGV under EUS guidance; (ii) contrast medium was subsequently injected without removing the needle; (iii) if the infused contrast medium stayed in the IGV and feeding vein, sclerosant was then injected to obliterate the IGV and feeders. Coil deployment in the IGV was successfully performed in all cases. Sclerosant was injected both into the IGV and feeders in seven patients (87.5%). There was no adverse event during the procedure. During a median follow-up of 57 months, one patient who could not inject the sclerosant into IGV and feeders had an early hemorrhagic recurrence. Our case series showed that EUS-CS could be a feasible and safe procedure for the treatment of IGV.
