THE ANALYSIS OF THE LASTING RESULTS OF THE PALLIATIVE ENDOBILIARY STENTING BY THE BILE DUCTS' OBSTRUCTION OF MALIGNANT AETIOLOGY

The article presents the proper observing experience of lasting results of the endoscopic stenting in patients suffering from the malignant pathology of the biliopancreatoduodenal organs complicated by the bile duct obstruction. The functioning periods of different implant models have been analyzed in dependence of the tumour localization, the used materials and their implant configurations. Within the study it has been revealed that the service period of implants had significantly varied in patients having both the homogeneous pathology and implant characteristics. This was possible for us to substantiate the necessity of evaluation for the metabolic bile disorders, on basis of which it is possible to forecast the risks of lithogenesis and the service period for implants that by-turn allows us to optimize the algorithm of choosing an implant and also will leads to the increase in frequency of occurrences of their premature obstruction.
