Case description

A 75-year-old patient presents with acute cholangitis and a history of open surgery for acute cholangitis 40 years ago. CT scan reveals a 12 mm common bile duct (CBD) containing a 12 mm stone

During ERCP, a stenotic duodenal ulcer was identified, requiring balloon dilatation up to 15 mm to allow passage of the duodenoscope through the stricture. Upon inspecting the second part of the duodenum, the papilla was not visible despite the presence of significant bile. This raised suspicion of a CBD anastomosis connected to the first part of the duodenum (D1).

Further exploration revealed a narrow entrance to the CBD just beyond the pyloric region. A guide wire was successfully advanced, followed by a 12-15 mm balloon catheter. The balloon was dilated up to 13 mm, deflated, and maneuvered into the upper part of the CBD. Subsequently, the balloon was gently inflated without applying pressure, allowing the extraction of the stone.
