When to puncture, when not to puncture: Pancreatic masses

Area of Science:

• Gastroenterology
• Oncology
• Medical Imaging

Background:

• Endoscopic ultrasound (EUS) is vital for evaluating pancreatic diseases, especially solid lesions.
• Distinguishing malignant from benign pancreatic lesions solely via EUS imaging remains challenging.

Purpose of the Study:

• To review the diagnostic accuracy and complication rates of EUS-guided fine needle aspiration (EUS-FNA) for pancreatic lesions.
• To clarify the current indications for tissue diagnosis of potentially malignant pancreatic lesions using EUS-FNA.

Main Methods:

• Literature review focusing on diagnostic accuracy and complications of EUS-FNA for pancreatic lesions.
• Analysis of current clinical indications for EUS-FNA in suspected malignant pancreatic diseases.

Main Results:

• EUS-FNA provides high accuracy for cytological and histological sampling of pancreatic lesions.
• EUS-FNA is associated with low complication rates.
• Despite its proven utility, indications for EUS-FNA in potentially malignant pancreatic lesions are still debated.

Conclusions:

• EUS-FNA is a valuable tool for diagnosing pancreatic lesions, complementing EUS imaging.
• Further clarification on EUS-FNA indications may optimize its clinical application for pancreatic cancer diagnosis.
