Successful EUS-FNO in group B was defined as positive EUS-FNO from either 1 of 2 passes of EUS-FNO. Techniques for taking tissue from pancreatic cancer are the standard technique of EUS-guided fine needle biopsy (EUS-FNB) using a 20-gauge forward-bevel needle. Tissues from the first and second puncture were collected into separate test tubes that were frozen to control temperature and taken to a laboratory room for organoid culture. The success in pancreatic organoid creation is considered initial success when we could isolate organoids (P0). When organoids grow and are confluent in the Matrigel plate, we would pass the cell to grow in the other Matrigel plate and repeat the passing process until 5 passages of growth. Complete success is defined when we could establish pancreatic organoid lines for ≥5 passages of growth (P5). These processes were performed before standard EUS-FNB for histopathology.
