“…Nine patients were considered non-diagnostic for pancreatic lesions because the mean number of needle passes was insufficient (2.6 passes) and an adequate sample was not obtained. LeBlanc et al (27) recommend that at least seven passes with a fine needle into pancreatic lesions are required to ensure a high degree of certainty for making a correct diagnosis. Among the patients in the present study, there was one case that was diagnosed as a mass-forming focal chronic pancreatitis (MFP); yet misdiagnosed as pancreatic cancer before surgery or FNA was performed because pancreatic carcinoma could not be absolutely ruled out under EUS (Figs.…”
