A 69-year-old man underwent endoscopic bile duct stone removal and bile duct stent placement for common bile duct and gallbladder stones in 2020. CT showed residual bile duct stent and stones around the stent, leading to a diagnosis of cholangitis due to bile duct stones. Endoscopic retrograde cholangiopancreatography (ERCP) was performed, the stent was torn during attempts at removal. After another attempt to remove the stones was unsuccessful, extracorporeal shock wave lithotripsy (ESWL) was performed. However, stone removal proved difficult, and electronichydraulic lithotripsy (EHL) was performed. The stone was successfully crushed, and the stone was removed along with the stent. The stone and granulation were adherent to the stent.
Stones forming around a long-implanted bile duct stent are a rare complication called stent-stone complex (SSC). In this report, we describe a case of SSC that was difficult to remove endoscopically, and review related literature.
