Clinical usefulness of tissue acquisition of pancreatic cystic lesions using an endoscopic ultrasound-guided needle for histological analysis.

There are rare data on the usefulness of endosonography-guided tissue acquisition (EUS-TA) in patients with pancreatic cystic lesions (PCLs). This study aimed to determine the accuracy of EUS-TA with ProCore 20G (PC20) for differentiating between mucinous neoplasia (MN) and non-MNs (n-MN) and identifying malignant PCLs, as well as its adverse events (AEs) in patients with PCLs without a classificatory diagnosis by imaging exams. In this observational, retrospective, single-center study, all patients with PCL who underwent EUS-TA due to diagnostic doubts in imaging studies were consecutively recruited from June 2017 to December 2021.

Endosonography Diagnosis with a New ProCore 20G of Mediastinal Metastasis from a Malignant Cutaneous Melanoma.

Melanoma is an uncommon tumor and represents about 1.5% of all neoplasms. In the mediastinum, it presents as a primary neoplasm or metastasis.

Comparison of endoscopic resection techniques for duodenal neuroendocrine tumors: systematic review.

Regardless of size, duodenal neuroendocrine tumors (dNETs) should be considered potentially malignant. A complete resection without complications is essential to increase safety procedures. The aim of this review was to describe effectiveness and possible complications of endoscopic techniques resection for resectioning dNETs in patients with tumors ≤ 20 mm in diameter.

Nonsteroidal anti-inflammatory drug effectivity in preventing post-endoscopic retrograde cholangiopancreatography pancreatitis: A systematic review and meta-analysis.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is the primary therapeutic procedure for the treatment of diseases affecting the biliary tree and pancreatic duct. Although the therapeutic success rate of ERCP is high, the procedure can cause complications, such as acute pancreatitis [post-ERCP pancreatitis (PEP)], bleeding and perforation.

Aim: To assess the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) in preventing PEP during follow-up.

EUS-FNA Diagnosis with Core Biopsy of Pancreatic Metastases from Primary Breast Cancer.

Background: The pancreas as a site of metastasis of other primary tumors is a rare event. Pancreatic metastases may occur years after the start of treatment of a neoplasm of another organ or may be the initial manifestation of an unidentified primary tumor. The most commonly reported primary sites for pancreatic metastases are the kidneys, lungs, breast, bowel, and skin (melanoma).
