ABSTRACT

The authors report their views on the treatment of unoperable neoplastic esophago-gastric stenoses with Nitinol prostheses. Despite a number of advantages (reduced trauma, greater tolerability) in relation to plastic prostheses, the paper highlights some problems (difficulty of unfastening, incomplete opening) which may be eliminated by improved materials.
