Abstract:

46-year old man with obstructive jaundice has a complication of hemobilia after performed earlier percutaneous transhepatic biliary drainage (PTBD). Angiography failed to localize the bleeding site, that is why selective therapeutic embolization was not done. We performed implantation of Gore stent-graft into biliary ducts, and hemobilia stopped immediately.

Abstract:

Aim: was to estimate possibilities of optical coherence tomography (OCT) in diagnostics of pathology of bile ducts in combination with percutaneous transhepatic biliary drainage (PTBD).

Materials and methods: examined 5 patients with obstructive jaundice, suspected cancerous etiology OCT was performed during or 5-14 days after PTBD. For morphological confirmation of results we performed forceps intraductal biopsies.

Results: tomographic evidences of the malignant stricture were revealed in 4 (80%) patients anc in 1 patient benign stricture was determined. Diagnoses were confirmed histologically (80%) and clinically (20%). Sensitivity of the OCT was 100%.

Conclusion: percutaneous transhepatic OCT appeared to be a perspective method for differential diagnostics of biliary strictures.
