Diagnostic Performance of Endoscopic Ultrasound-Guided Tissue Acquisition by EUS-FNB for Solid Pancreatic Lesion: a Tunisian Retrospective Study

Aims Endoscopic ultrasound (EUS) has been established as the reference for the histologic diagnosis of solid pancreatic lesions, as it is efficient and safe. It has been performed for several years in our country, but there are currently few data evaluating its performance. The aim of our study was to evaluate the performance of fine needle biopsy (FNB) in adults undergoing EUS –guided sampling of solid pancreatic lesions.
