Intractable Pancreatic Stone Removal Using SpyGlass™ DS II with Electrohydraulic Lithotripsy: A Case Report and Literature Review

Pancreatic stones are a common finding of chronic pancreatitis and may causerecurrent abdominal pain and pancreatitis. Pancreatic stones are often accompaniedby stenosis of the pancreatic duct and are often impacted within the pancreaticduct, so it is not easy to remove the pancreatic stones using a basket. Until now,extracorporeal shock wave lithotripsy has been used, but it requires repeatedprocedures and the success rate is not very high. The recently developed SpyGlass™DS II (Boston Scientific, Marlborough, MA, USA) has a 3.5 mm diameter that allowsinsertion into the dilated pancreatic duct, it is possible to remove the pancreaticstones using electrohydraulic lithotripsy (EHL) or laser lithotripsy while directlyviewing the pancreatic stones. In this paper, we would like to introduce a method toremove multiple pancreatic stones larger than 10 mm using SpyGlass™ DS II with EHL.
