Tips to overcome technical challenges in EUS-guided tissue acquisition

Peter Vilmann et al. Gastrointest Endosc Clin N Am. 2014 Jan.

Abstract

The diagnostic yield of EUS-FNA depends on several factors, such as the experience of the endosonographer, the characteristics of the lesion, the clinical status of the patient, the size and type of needles, the methods of specimen preparation, as well as cytopathologist expertise. The endosonographic technique can be improved when several tips and tricks useful to overcome challenges of FNA are known. Technical challenges of FNA are related to the characteristics of the lesion and its surroundings, sonographic imaging, and limitations related to the needle. Several tips and tricks necessary to overcome them are presented in this review.

Keywords: EUS guided biopsy; EUS-FNA technique; Endoscopic ultrasound (EUS); Fine needle aspiration (FNA); Tissue acquisition.
