POSSIBILITIES OF OPTICAL COHERENCE TOMOGRAPHY IN DIFFERENTIAL DIAGNOSTICS OF BILIARY TRACT STRICTURES
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.
