| Popis: | Aim. Expand and determinate indications for using of extraction balloon catheters in endoscopic biliary surgery, as an additional and auxiliary endoscopic technique, which optimizes the technical conditions for performing medical and diagnostic tasks.Material and methods. We used disposable two- and three-lumen extraction balloon catheters with a diameter of 7.5 Fr. The catheters assumed delivery of an extractor balloon along a conductor with a diameter of 0.35 in into the bile duct, and also made it possible to inject a radiopaque substance. 136 retrograde endoscopic interventions were performed on the bile ducts using extraction balloon catheters.Research results. Indications for the use of an extractor balloon have been determined and proposed as a conventional standard. Interventions on the bile ducts were carried out using only a balloon catheter and in combination with a Dormia basket (n = 61). An extraction balloon catheter was used during retrograde endoscopic intervention on the bile ducts as an additional diagnostic endoscopic manipulation to facilitate the performance of the diagnostic task (n = 38). The device was also used to optimize the technical conditions of medical and diagnostic tasks (n = 37). 116 patients had benign diseases, 20 patients had tumor lesion.Сonclusion. The main function of an extraction balloon catheter is to move or displace the contents from the proximal to the distal parts of the bile duct, followed by its extraction into the duodenum. The design characteristics of the instrument make it possible to significantly expand the indications for its use, including not for its intended purpose, but as an additional method, optimizes the technical conditions for performing medical and diagnostic tasks. The endoscopic extraction balloon catheter is a multipurpose instrument that can be used to solve both diagnostic and therapeutic tasks of retrograde interventions on the bile ducts. |
