Radiosurgical Maintenance of Indeterminate Proximal Biliary Stricture. Clinical Observation

The paper presents a case of an indeterminate proximal biliary stricture in a patient who admitted to the N.N. Blokhin National Medical Research Center of Oncology with a referral diagnosis of Klatskin tumor and 6 years earlier had undergone cholecystectomy for calculous cholecystitis complicated by Mirizzi syndrome. The authors highlight the difficulties of biliary lesion differentiation as well as the importance of anamnestic, clinical, imaging, laboratory and morphological data synthesis with the emphasis on percucationous endobiliary interventions to establish the etiology of the disease.
