Electrohydraulic lithotripsy for ball valve syndrome due to stent-stone complex after endoscopic ultrasound-guided hepaticogastrostomy.

Abstract

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is the standard endoscopic procedure for malignant biliary obstruction [1] [2]. However, the rate of EUS-HGS-associated adverse events remains high, and various severe complications, including risk factor and rescue techniques, have been reported [3] [4] [5]. We present a rare case of electrohydraulic lithotripsy (EHL) for ball valve syndrome due to a stent-stone complex after EUS-HGS.
