Introduction: Self-expandable metal stents (SEMS) are widely used in the management of difficult common bile duct (CBD) stones. Similarly, endoscopic placement of multiple plastic biliary stents & stent within a stent have also been reported for complex choledocholithiasis or benign biliary strictures as a safe alternative to surgery. We report the transpapillary placement of double, side-by side CBD metal stents in a patient with complex bile duct stones.

Case Description/Methods: A 90-year-old Pt. with multiple comorbidities deemed not a candidate for surgery presented with recurrent rt. upper quadrant abdominal pain & fever. A CT scan of the abdomen confirmed acute cholecystitis complicated by contained perforation. She also had multiple CBD stones with the largest stone measuring 22 mm & CBD size 23 mm. She had normal liver tests. She underwent an ERCP with sphincterotomy, & removal of multiple large CBD stones followed by saline irrigation to remove the sludge. Percutaneous cholecystostomy was performed considering her being a poor surgical candidate. Follow up cholecystostomy check after 3 weeks identified multiple large filling defects in CBD & the gallbladder. A repeat ERCP & cholangiograms confirmed persistently dilated CBD to 24 mm & large CBD stones. Multiple attempts to clear the CBD failed even after using a cholangioscopy-guided electrohydraulic lithotripsy with high power & stone extraction basket. The sphincterotomy site was dilated with a TTS balloon to 18 mm followed by sequential placement of two Viabil SEMS (10 mm x 10 cm & 8 mm x 8 cm) into the CBD with an intention of preventing stent migration. To our best knowledge, we present the first case report regarding the safe placement of two side-by-side transpapillary metal stents into the CBD. The patient remained well one week after the procedure with no complications.

Discussion: Transpapillary placement of side-by-side SEMS into the CBD may be safely performed for successful biliary drainage in a select group of patients with complex choledocholithiasis. Twin CBD stents might prevent stent migration.
