Intrahepatic Cholangiolithiasis Extraction During Endoscopic Retrograde Cholangiopancreatography Using a Disposable...

Area of Science:

• Gastroenterology
• Hepatology
• Endoscopic Procedures

Background:

• Hepatolithiasis involves stones in intrahepatic bile ducts, often causing infections and strictures.
• Standard endoscopic retrograde cholangiopancreatography (ERCP) can be difficult for treating hepatolithiasis.
• Effective management of intrahepatic bile duct stones remains a clinical challenge.

Purpose of the Study:

• To describe a novel endoscopic retrograde cholangiopancreatography (ERCP) technique for hepatolithiasis.
• To evaluate the efficacy of a disposable ultrafine peroral cholangioscope in treating intrahepatic cholangiolithiasis.
• To showcase direct visualization and stone extraction in the intrahepatic bile ducts.

Main Methods:

• A step-by-step description of an ERCP procedure utilizing a novel disposable ultrafine peroral cholangioscope.
• Direct visualization of the intrahepatic bile ducts during the procedure.
• Percutaneous removal of stones from the intrahepatic bile ducts.

Main Results:

• Successful removal of stones from the intrahepatic bile ducts in a patient with hepatolithiasis.
• Demonstrated the immediacy and efficiency of peroral cholangioscopy in navigating intrahepatic anatomy.
• Confirmed the feasibility of stone extraction under direct visualization using the novel scope.

Conclusions:

• The novel disposable ultrafine peroral cholangioscope offers an effective method for treating intrahepatic cholangiolithiasis.
• Direct visualization via peroral cholangioscopy enhances stone removal in challenging hepatolithiasis cases.
• This technique provides valuable insights for future management of similar conditions.
