Percutaneous Cholangioscopy in the Management of Biliary Disease: Experience in 25 Patients

Abstract

Purpose: To present our experience performing percutaneous cholangioscopy in the management of 25 patients with biliary disease.

Methods: During the last 3 years, 26 percutaneous cholangioscopies were performed in 25 patients with common bile duct disease (n = 16), intrahepatic ducts disease (n = 6), and gallbladder disease (n = 4). Our patient population group included seven with common bile duct stones, three with intrahepatic lithiasis, and eight with benign strictures (six iatrogenic and two postinflammatory). In four patients malignancy was to be excluded, in two the tumor extent was to be evaluated, whereas in one case the correct placement of a metallic stent needed to be controlled. A 9.9 Fr flexible endoscope URF-P (Olympus, 1.2 mm working channel, 70-cm length) was used.

Results: In total, percutaneous cholangioscopy answered 30 diagnostic questions, was technically helpful in 19 cases (performing lithotripsy or biopsy or guiding a wire), and of therapeutic help in 12 (performing stone retrieval). In 24 of 26 cases the therapeutic decision and the patient management changed because of the findings or because of the help of the method. In two cases biliary intervention failed to treat the cause of the disease. No major complication due to the use of the endoscopy was noted.

Conclusions: Percutaneous cholangioscopy is a very useful tool in the management of patients with biliary disease. The method can help in diagnosis, in performing complex interventional procedures, and in making or changing therapeutic decisions.
