DIAGNOSTIC YIELD OF EUS FNA IN PANCREATIC MASSES : CORRELATION BETWEEN THE CONSERVATIVE USED AND PATHOLOGICAL RESULT

Aims To evaluate the yield of EUS FNA in the diagnosis of pancreatic masses and establish a correlation between the conservative used and pathological results

Methods A retrospective descriptive study, from August 2016 to August 2021, including 106 EUS-FNA performed and 99 patients with a pancreatic mass. Data regarding the results were analysed by SPSS.

Results

Mean age was 63.3 years; sex ratio was 1. Mean lesion size was 4 cm; needle used was 22G in 87.7%; techniques frequently used were “slow pull” associated with aspiration in 50% of cases and slow pull alone in 43.4%; the mean pass number was 2.4; conservative was chosen in concert with anatomopathologists; cytolite and formalin in 34%, cytolite alone in 20%, slide spreading+formalin in 16%, and saline alone in 7.5% of cases; a combination of several conservatives was possible. Cell block procedure was performed in 82.4%. The association of cytological and cell block procedure revealed the following results : pancreatic adenocarcinoma in 65.6%; pancreatic adenosquamous carcinoma in 2%; pancreatic lymphoma in 1%; metastasis of pulmonary keratinizing squamous cell carcinoma in 1% ([Figure 1]: a-c: aspiration, d: cell block), pancreatic carcinoma in situ in 1%; solid and pseudo-papillary pancreatic tumor in 2%; pancreatic tuberculosis, mucinous cystadenoma, autoimmune pancreatitis, and chronic pancreatitis respectively in 1%. 3 cases of minimal bleeding, resolved spontaneously, were noted.

Conclusions The yield of EUS FNA in the diagnosis of pancreatic masses in our experience was 80%. Most used conservative was cytolite alone or combined in 65%; confirming a conclusive diagnosis in 53.7%.
