[Use of self-expanding stents in benign and malignant esophageal disease].
Of patients with malignant esophageal tumors, more than the half has incurable disease at the time of diagnosis. In such cases, quality of life and ability to swallow should be improved or restored by palliating the process e.g. by inserting esophageal stents. In the recent years, use of covered self-expandable metal stents (SEMS) has led to an increased success rate in the palliative treatment of--mainly malignant--strictures of the esophagus. High occurrence of complications (perforation, bleeding) associated with the use of rigid plastic esophageal stents necessitated the development of flexible stents. First generation self-expandable stents were made of special metal alloys, such as nickel-titanium. In the recent years, self-expandable plastic stents are available, too, offering new alternatives in the palliative treatment of esophageal diseases. In our present review article, we discuss the most important aspects about the use of self-expanding esophageal stents, based on recent clinical observations and data.
