Patient enrolment and baseline data
Between January and February 2020, 46 patients were recruited, two of them were unable to withstand anesthesia, and five of them were lost to follow‐up. Finally, a total of 39 patients included 26 men and 13 women with a mean age of 58.8 ± 12.2 years (range: 30–81 years) were included. All patients had CH‐EUS examination and were then randomized to undergo either traditional EUS‐FNA (Control group) or CH‐EUS MASTER‐guided EUS‐FNA (CH‐EUS MASTER group). The trial flowchart is illustrated in Figure Flowchart of the clinical trial.The demographic details, laboratory tests, and pancreatic mass baseline characteristics of the included patients are presented in Table The demographic details, laboratory tests, and pancreatic mass baseline characteristics of 39 patients included in the study
