Choledochoscopy

Direct visualization allows clinicians to inspect abnormalities within the biliary tree rather than relying only on indirect imaging findings. This can help distinguish possible stones, strictures, and suspected tumors when imaging does not fully explain an obstruction. The resulting visual information may increase diagnostic confidence and support a more individualized management decision.

Irrigation helps maintain the visual field during inspection, while the working channel permits additional procedures through the scope. These features allow clinicians to move beyond observation by obtaining tissue samples, retrieving stones with a basket, or applying intraductal lithotripsy. Together, they make the examination useful for both diagnosis and targeted treatment.

Direct inspection provides detailed visual assessment of areas that may represent a stricture or tumor, while tissue sampling can provide additional diagnostic evidence. This combination links the appearance of a lesion with material for evaluation, helping clinicians investigate unclear biliary disease more directly than imaging alone can support.

The scope may reach the common bile duct through peroral, percutaneous, or surgical access. Once access is established, irrigation supports visualization and the working channel enables sampling or treatment. The examination can therefore be configured around the patient’s biliary problem and the need for inspection, tissue acquisition, stone retrieval, or lithotripsy.

When stones are identified, the technique can support basket retrieval or intraductal lithotripsy. These capabilities connect the diagnostic examination with a targeted response to the observed obstruction. In complex biliary disorders, that combination may help clinicians tailor management to the location and nature of the stone-related problem.

Choledochoscopy is particularly relevant when biliary obstruction or disease remains insufficiently explained, including cases involving stones, strictures, or suspected tumors. Its value extends across diagnostic and therapeutic decisions because it can provide direct inspection, tissue sampling, and focused intervention. This is especially useful for complex biliary disorders requiring individualized treatment planning.
