The term "stent biliary v-e-01p-5fr (single pigtail)" refers to a specific type of biliary stent, commonly used in biliary interventions. Here’s a breakdown of the components:

• Stent: A tubular device used to maintain the patency (openness) of a duct, such as the bile duct.
• Biliary: Refers to the bile ducts, which transport bile from the liver and gallbladder to the small intestine.
• V-e-01p: Likely represents the model, type, or variant of the stent.
• 5fr: Refers to the diameter of the stent in French gauge (Fr), with 5 French units being approximately 1.67 millimeters (1 Fr = 0.33 mm).
• Single Pigtail: This means the stent has a curled or coiled design at one end, resembling a pig's tail. The pigtail is designed to prevent the stent from migrating or moving out of place by anchoring it at one end in the bile duct.

This type of stent is commonly used to treat bile duct obstructions, such as those caused by gallstones, strictures, or tumors, and can be placed endoscopically.
