The term "stent biliary v-e-12d10fr (double pigtail)" refers to a particular type of biliary stent with a specific design and characteristics:

• Stent: A device used to hold open a structure within the body—in this case, the bile duct.
• Biliary: Pertains to the bile ducts, which carry bile from the liver and gallbladder to the small intestine.
• V-e-12d10fr:
  • "V-e-12d": Likely refers to the specific model or variant of the stent.
  • "10fr": Refers to the French gauge (Fr), with 10 French (Fr) indicating a diameter of approximately 3.33 millimeters.
• Double Pigtail: This design feature refers to the ends of the stent, which are curled or coiled like pig tails. This design is intended to help the stent stay in place and reduce the risk of migration. The double pigtail shape allows the stent to anchor itself effectively in both ends of the bile duct.

These stents are typically used in cases of bile duct obstruction due to strictures, tumors, or other medical conditions, ensuring the bile can flow freely.
