Abstract

Recently, peroral direct cholangioscopy (PDCS) using an ultra-slim endoscope has come into the spotlight. However, the working channel is too small to use various devices for lithotripsy. We report a case of endoscopic lithotripsy with PDCS using a conventional endoscope as a cholangioscope. Computed tomography scan on an 80-year-old female who was admitted with acute cholangitis showed two large stones in the bile duct. Endoscopic retrograde cholangiopancreatography was attempted first. However, mechanical lithotripsy failed because the stone was too large for the basket catheter. Finally, electric hydraulic lithotripsy with PDCS using a conventional endoscope was performed allowed the stones to be cleared completely. In conclusion, PDCS using a conventional endoscope can be an alternative solution for endoscopic lithotripsy for patients with large stones in the dilated bile duct.
