Abstract

enAt the Cliniques universitaires Saint-Luc, 390 EUS guided punctures (EUS-FNA/FNB) of the pancreas were performed over a period of five years, between 2014 and 2019. These were performed to characterize suspicious pancreatic masses and diagnose pancreatic tumors. Although this technique is constantly evolving and improving, it still seems to be some misdiagnosis. For this reason, it was considered interesting to retrospectively evaluate the diagnostic reliability of punctured pancreatic masses within the large centre of expertise that is Cliniques universitaires Saint-Luc. To do this, a CRF (Case Report Form) created on the website www.castoredc.com was used to collect all the data (such as the patient's age, the date of the puncture, but also the presence or absence of chronic pancreatitis, the size and location of the suspected mass, the size of the needle used, the type of needle used: FNA vs FNB, the number of passes made through the mass as well as the various anatomopathological analyses performed). No confidential patient data was mentioned on this CRF. A random patient ID system was established to ensure this confidentiality. Next, different factors were studied in order to identify the variables that influence the diagnostic reliability of suspicious pancreatic masses by EUS guided puncture. To this end, sensitivity and specificity calculations of this diagnostic technique as well as χ^2 tests of independence of different factors were performed. Then, our results were compared with different data published in the recent scientific literature.
