Endoscopic and echographic imaging and tactile sensitivity are similar to the real one. Conclusion: The models described in this study demonstrated to be realistic, easy to reproduce and allow repetition during the same session. However, comparative studies are necessary to verify the real impact on teaching.

Ideally, the needle for ultrasound guided endoscopic fine needle aspiration should have specific features. Obviously, it should be resistant enough to drill the central airway wall, without the risk of damage or, even worse, breakages associated with the contact with cartilages or during the needle pushing up and down. At the same time, a

Endoscopic ultrasound (EUS)‑guided fine‑needle aspiration (EUS‑FNA) is highly accurate in obtaining specific diagnoses for various diseases. The present study aimed to evaluate the diagnostic yields, accuracies and sampling adequacies, of slow-pull, 5 ml suction and 10 ml suction techniques in EUS-FNA of solid lesions. The present study

Endobronchial Ultrasound: A New Tool for Pulmonologists

Oesophageal endoscopic ultrasound (EUS) and fine needle aspiration (FNA) under its guidance had been in practice for gastrointestinal malignancies as well as accessible para-oesophageal lymphnodes since 1980s [6]. However, the probe was too big and was not suitable for use in the airways. It took more than a decade to develop an endobronchial

Endoscopic Ultrasound-guided Liver Biopsy

Fine-needle aspiration Fine-needle biopsy KEY POINTS Endoscopic ultrasound guided liver biopsy (EUS-LB) is emerging as a cost-effective, safe, and well tolerated approach to liver biopsy. The ability of EUS-LB to target widely separated areas of liver allows more representative sampling.

Issue Highlights

Fine-needle Biopsy and Aspiration Techniques Endoscopic ultrasound (EUS) with fine needle aspiration (FNA) is the standard diagnostic procedure for tissue sampling of solid lesions within adjacent to the GI tract. However, FNA has limita-tions that can eliminated if a larger tissue sample is obtained. A fine needle biopsy (FNB) device that has

Open Access Endoscopic Ultrasound Fine-Needle Aspiration

Background/Aims: Endoscopic ultrasound fine-needle aspiration (EUS-FNA) is preferred for sampling of lymph nodes (LNs) adjacent to the gastrointestinal wall; however, fine-needle biopsy (FNB) may provide improved diagnostic outcomes. This study aimed to evaluate the comparative efficacy and safety of FNA versus FNB for LN sampling.

EUS-FNA: Wet Suction Technique

Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) has been widely utilized to diagnose a range of gastrointestinal diseases. (1,2). The literature surrounding EUS-guided FNA techniques generally involves the use of a needle, with or without suction, or a slow-pulling technique with the stylet (3, 4, 5).

of endoscopic ultrasound-fine needle aspiration is affected by several factors such as different needle sizes and types and fine needle aspiration techniques. Several comparative studies have been published on various techniques, such as the use of a stylet and suction during fine needle aspiration.

Use of suction during endoscopic ultrasound-guided fine

Endoscopic ultrasound-guided tissue acquisition (EUS-TA) has become the procedure of choice for pathological diagnosis of solid pancreatic lesions [1]. Since its introduction, EUS fine-needle aspiration (FNA) had been done with narrow-caliber needles. This technique, asso-ciated with the processing of the material obtained in smears,

open Access Present and Future of Endoscopic Ultrasound

Endoscopic ultrasound-guided tissue acquisition (EUS-TA) is a well-established method for pathological diagnosis of solid pancreatic neoplasm. It can be performed either as EUS-guided fine-needle aspiration (EUS-FNA) or EUS-guided fine-needle biopsy (EUS-FNB). The incidence of adverse events related to EUS-TA is less than 1%.
