[Self-expanding nitinol stent--use in esophageal carcinoma].
In recent years the implantation of self-expanding metal-stents has been recommended as a palliative kind of therapy for dysphagia caused by esophageal carcinoma. The metal-stent has a high flexibility, so that it can fit according to the preformed angel of the esophagocardial transition and does not cause a feeling of pressure when placed in the cervical position. From July 1992 to February 1995 in the surgical department of the University of Bonn 21 patients have got a self-expanding Nitinol stent. No dislocation, bleeding or perforation occurred. The dysphagia improved in all patients. The lethality rate was 9.5%, the mean survival rate 4,6 month. The growth of the tumor through the mesh of the stent was a problem which occurred from the tenth week onwards after implantation. Even when the self-expanding metal-stent does not solve all problems, it enlarges the spectrum of palliative kinds of therapy.
