Targeted and effective diagnosis guarantees more successful treatment prospects for patients with suspected malignant bile duct tumors. We present a percutaneous bile duct biopsy kit used for percutaneous transluminal bile biopsy, allowing efficient extraction of a highly accurate histological specimen. This kit will enable you to apply an improved Cross and Push methodology during the procedure. This is a safer and more accurate choice for access and tissue biopsy from the bile duct system than standard bile sampling techniques performed during percutaneous aspiration biopsy, intraluminal bile lavage, and bile cytological analysis procedures.
