X-RAY controlled implantation stents to stenoses in gastrointestinal system.
CERKUNÍKOVÁ, Anna
X-ray controlled stent implantation into gastrointestinal tract stenoses is a modern mini-invasive method. Many medicine branches have gone through considerable development in the second half of 20th century. In many cases it has been based on new discoveries in disease pathogenesis, new approaches in therapy and most importantly on new technical possibilities. This thesis describes treatment of stenotic tumors in gastrointestinal tract that used to belong to frequent surgery indication, regardless of possible radicality. Intervention radiology is a dynamic and quickly developing specialisation. New material and procedures development extends the possibilities of mini-invasive therapy in gastrointestinal tract illness. Instead of surgery, stent implantation is indicated in many cases. This method has many advantages when comparing with surgery, e.g. lower invasivity without general anesthesia usage and short recuperation. Indications of stent implantation into gastrointestinal tract stenoses can be divided according to more aspects, e.g. stenosis localisation, stenosis etiology, inborn or acquired stenoses and last but not least benign and malign stenoses that are the main topic of this thesis. The aim of this thesis is success and effectively assessment in stent implantation into gastrointestinal tract stenoses. The procedures are divided according to stenosis localisation in a certain period. The results are compared with other centers in the Czech Republic. In every procedure, we assess the etiology, stenosis localisation, patient age and sex, procedure type and its success rate, early and late complications (to 30 days from the procedure). As in the majority of cases we analysed patients with inoperable malign tumors, the mortality was not assessed. This thesis confirms the only chosen hypothesis ? the stent implantation in gastrointestinal tract stenosis is a quick and effective method with a low number of complications. Our department wants to use the data acquired in practise to compare the success rate and complication number with other centers and according to the results to confront the procedure method.
