It was reported to boston scientific corporation that a hot axios stent was implanted in a transduodenal position to facilitate biliary drainage during an endoscopic ultrasound (eus) guided biliary drainage procedure performed on (b)(6) 2019.Reportedly, the patient had locally advanced inoperable pancreatic cancer and severe chronic obstructive airway disease (coad).The patient had previously undergone a failed endoscopic retrograde cholangiopancreatography (ercp) procedure.According to the complainant, during the procedure, the bile duct was punctured using a 19 gauge eus needle and a guide wire was passed into the bile duct.A cholangiogram was performed to confirm access to the bile duct.The hot axios stent was placed using eus visualization, and following the stent placement, bile was observed to be draining into the duodenum through the stent.The guide wire was removed, and the physician checked the stent position using eus.The physician felt that the stent was appropriately positioned.Reportedly, the patient did not do well overnight, and a computed tomography (ct) scan showed that the distal flange of the stent was located between the bile duct and the duodenum.The patient refused further treatment and died later that night.The clinical cause of the patient's death was sepsis related to a leak from the gastrointestinal (gi) and biliary tract.According to the physician, upon reflection, the imaging was complex, and although he felt it was appropriately positioned during the procedure the physician could not absolutely confirm the first flange was inside the bile duct.He stated that "in retrospect i may have pushed the bile duct wall away from the duodenum and deployed the distal flange in a false space between the duodenum and bile duct".
