Main Pancreatic Duct Diameter

Normal Values of Main Pancreatic Duct Diameter

The maximal diameter of the pancreatic duct will be measured by endoscopic ultrasound at four different parts:

• Pancreatic head
• Pancreatic neck
• Pancreatic body
• Pancreatic tail

Study Overview

• Status: Recruiting
• Conditions: Pancreatic Duct Dilatation

Detailed Description

All patients without pancreatic or biliary disorders undergoing upper-GI endoscopic ultrasound (EUS) are eligible for the study.

The maximal diameter of the pancreatic duct will be measured by endoscopic ultrasound in millimeters at four different parts:

• Pancreatic head
• Pancreatic neck
• Pancreatic body
• Pancreatic tail

• Study Type: Observational
• Enrollment (Estimated): 102
