BACKGROUND An 81-year-old patient presented to our center with pancreatic head cancer,obstructive jaundice,and acute cholecystitis.Due to duodenal tumor infiltration,both endoscopic retrograde cholangiopancreatography and endoscopic ultrasound(EUS)-guided choledochoduodenostomy were technically challenging.CASE SUMMARY An EUS-guided gallbladder drainage along with an EUS-guided fine needle biopsy were performed,resulting in a diagnosis of pancreatic cancer resolution of jaundice and improvement in acute cholecystitis,all in a safe and effective single endoscopic session.CONCLUSION This case demonstrated the successful use of EUS-guided gallbladder drainage and EUS-guided fine needle biopsy in a patient with pancreatic cancer invading the duodenal wall.
