Endoscopic ultrasound guided fine needle aspiration of solid pancreatic lesions: Performance and outcomes

Abstract

Our experience confirms that EUS-FNA in patients with suspected solid pancreatic lesions is safe and has a high diagnostic accuracy. This technique should be considered the preferred test when a cytological diagnosis of a pancreatic mass lesion is required.

Characteristics of Small Pancreatic Carcinoma: Neural Invasion is Associated with Tumor Recurrence

“…Maguchi et al [13] reported that the tumor detection rate of TS1 pancreatic carcinoma (≤2 mm) was 100%. Diagnosis by EUS-guided fine needle aspiration (EUS-FNA) at the time of tumor detection had a sensitivity of 85% to 94%, a specificity of 100%, and an accuracy of 95% [14] [15]. However, we should keep in mind that the accuracy would be lower for tumors ≤ 1 mm [16].…”

Endoscopic ultrasound (EUS) guided fine needle biopsy (FNB) with the Procore™ needle provides inadequate material for the histological diagnosis of early chronic pancreatitis

“…EUS-guided FNA and FNB are safe and accurate techniques for the cytohistological evaluation of solid pancreatic lesions (13)(14)(15)24,25,28). The use of reverse-beveled Procore™ needles provides a high diagnostic yield in this setting (17)(18)(19)29,30).…”

“…The implementation of tissue acquisition via EUS in solid pancreatic lesions has had a major impact on the diagnosis and subsequent management of pancreatic cancer (8)(9)(10)(11)(12). Moreover, EUS-guided fine needle aspiration (FNA) or biopsy (FNB) is safe and reliable (13)(14)(15). Data on the role of EUS-FNB in early CP are scarce (16).…”
