Choledocholithiasis in RIPD/CCD. (a) Each image shows the following: pancreas divisum as seen on the 2D T2 thick-slab turbo spin echo image (top left), stone in the duct of Santorini as seen on the axial fat-saturated T2 weighted image (arrow in top right), stone in the RIPD/CCD (arrow) as seen on the 2D T2 thick-slab turbo spin echo image MR image (bottom left), and removal of a stone from the duct of Wirsung through ERCP (bottom right). (b) In 18 patients, stones were identified in the RIPD/CCD. The observation was conducted in three asymptomatic patients, whereas in patients with larger stones or accompanying pancreatitis, stones were removed through ERCP. Four patients required ERPD due to severe stenosis of the pancreatic duct, and except for two patients, all required ERCP procedures more than twice. *RIPD: remnant intrapancreatic common bile duct; CCD: common channel duct; MR: magnetic resonance; ERCP: endoscopic retrograde cholangiopancreatography: ERPD: endoscopic retrograde pancreatic drainage.
