ABSTRACT
A 76-year-old woman with advanced pancreatic cancer developed recurrent cholecystitis after covered self-expandable metal stent (CSEMS) placement. The cholecystitis was refractory to repeated percutaneous transhepatic gallbladder drainage (PTGBD). Cholecystography showed a patent cystic duct with right and cranial side bifurcation, which is indicative of an increased likelihood of success of endoscopic transpapillary gallbladder drainage (ETGBD). We were able to manage the cholecystitis by ETGBD without further recurrence. ETGBD is considered an effective internal drainage method for the management of acute cholecystitis after CSEMS placement, and its indication may be decided on the basis of the findings of cholecystography through the PTGBD route.
