Cholangioscopy offers new diagnostic and therapeutic options for bile duct stones and strictures. Both peroral and percutaneous approaches showed effectiveness, with percutaneous methods linked to higher complication rates.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Biliary Medicine

Background:

  • Cholangioscopy enables novel diagnostic and therapeutic interventions within the biliary system.
  • The procedure can be performed via peroral or percutaneous transhepatic routes, depending on anatomical suitability.

Purpose of the Study:

  • To evaluate the efficacy and outcomes of cholangioscopy for treating common bile duct (CBD) and intrahepatic stones, as well as malignant stenosis.
  • To compare the success rates and complication profiles of peroral versus percutaneous transhepatic cholangioscopy.

Main Methods:

  • Peroral cholangioscopy was attempted in 6 patients (5 with lithiasis, 1 with stenosis).
  • Percutaneous transhepatic cholangioscopy was utilized when peroral access was not feasible or failed, including 17 patients with CBD stones and 18 with intrahepatic stones.

  • Electrohydraulic lithotripsy and stent extraction were employed as therapeutic interventions.

    • Main Results:

    • Peroral cholangioscopy was successful in 4 out of 6 cases, with successful lithotripsy in 2 out of 3.
    • Percutaneous cholangioscopy achieved complete CBD stone clearance in 16 out of 17 patients.
    • Excellent or good results were reported in 18 patients with intrahepatic lithiasis, with lithotripsy or stenosis dilatation as needed.
    • Complication rates for lithiasis were 29.5% (CBD) and 27.7% (intrahepatic), with an 8.5% mortality rate, primarily associated with the percutaneous route.
    • For malignant stenosis, cholangioscopy facilitated diagnosis, stent extraction, and endobiliary laser treatment.

    Conclusions:

    • Cholangioscopy, particularly the percutaneous transhepatic approach, is an effective therapeutic option for complex biliary lithiasis and malignant stenosis.
    • While effective, the percutaneous route is associated with significant complication and mortality rates that require careful consideration.
    • Further research may focus on refining techniques to minimize complications associated with percutaneous cholangioscopy.
