  • presence in a patient of a plastic stent.In this case, inflammation of bile ducts, installed nazobiliarny dr
    ainage, which makes it possible to wash the bile duct aseptic.
  • obstructive jaundice.In this case, installing a metal or plastic stent, but only in the absence of contraindications to surgery.

two-stage stenting ducts made in the following situations:

  • postoperative stenosis (narrowing) of the biliary tract.To expand the channel, you must re-stenting.
  • cholangitis.In this situation the first set nazobiliarny drainage, and then - a metal or plastic stent.

cholangioscopy carried out with the participation of a nurse and two doctors.Premedication is to enhance the motility of the digestive system and the suppression increased salivation.In addition, before the procedure, the patient is administered sedatives and painkillers because the manipulation is carried painful and often causes anxiety, making it difficult to complete the survey.
