A schematic illustration of liquid‐based cytology. The collected pancreatic juice via an endoscopic naso‐pancreatic drainage tube should be immersed in the preservation solution for at least 1/2 h. The supernatant was discarded, and distilled water (DW) was added. The solution was centrifuged at 2000 rpm for 5 min. The supernatant was discarded, and 300 µl of DW was added. The solution was suspended and placed in a chamber attached to a glass slide that is positively charged in the center.
