Obstruction of the main pancreatic duct (MPD) by stones can cause debilitating pain in patients with chronic pancreatitis (CP). Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for detecting MPD ...

Carcinoembryonic antigen (CEA) levels measured from fluid obtained by EUS-FNA of pancreatic cystic neoplasms (PCN) are used to distinguish between mucinous and non-mucinous cysts. While high accuracy rates with levels >200 ...

Objectives: Observational data on the impact of on-site cytopathology evaluation (OCE) during endoscopic ultrasonography-guided fine needle aspiration (EUS–FNA) of pancreatic masses have reported conflicting results. We ...

Availability of onsite CyP evaluation during EUS FNA of SPL can increase diagnostic yield of malignancy with a significantly lower number of EUS-FNA passes. However, studies on clinical impact of onsite CyP have reported ...

Despite lack of evidence, use of a stylet during EUS-FNA is believed to improve quality and diagnostic yield of specimens. Use of a stylet is time consuming and increases cost of the needle. Recent pilot studies have ...

Duodenal Carcinoids (Neuroendocrine tumors, NETs) account for <2% of duodenal tumors found on endoscopy. The behavior of duodenal NETs remains unclear and consensus regarding management is lacking. There is limited data ...

Background: American Society for Gastrointestinal Endsocopy (ASGE) guidelines for assessing minimal competence in EUS are based on expert opinion and retrospective studies. Objective: To prospectively define learning ...
