Cholangioscopy is a specialized endoscopic procedure used to directly visualize and examine the bile ducts, allowing for the diagnosis and treatment of various biliary tract disorders. During cholangioscopy, a thin, flexible tube equipped with a miniature camera is inserted through the working channel of an endoscope and advanced into the bile ducts. This allows for high-definition imaging of the bile ducts' inner lining, enabling the detection of abnormalities such as stones, strictures, tumors, or parasites. Cholangioscopy offers several advantages over traditional imaging techniques, such as improved visualization and the ability to obtain targeted biopsies or perform therapeutic interventions directly. It can be performed as a standalone procedure or in conjunction with other endoscopic techniques, such as Endoscopic Retrograde Cholangiopancreatography (ERCP). Cholangioscopy plays a crucial role in the diagnosis and management of biliary tract disorders, providing clinicians with valuable information to guide treatment decisions and improve patient outcomes.
