Difficult removal of an endoscopic nasobiliary drainage tube after laparoendoscopic rendezvous surgery.

A 52-year-old female patient came to our hospital with upper abdominal pain over more than four days. Magnetic resonance cholangiopancreatography confirmed gallstones, common bile duct dilatation, and suspected choledocholithiasis. After the recommended preoperative preparation, the patient underwent laparoscopic cholecystectomy and intraoperative endoscopic retrograde cholangiopancreatography (ERCP), also called laparoendoscopic rendezvous surgery (LERV). During surgery sand-like stones were successfully removed from the common bile duct.
