Objective To investigate the intervention ways of endoscopes in the treatment of esophagus stenosis due to carcinoma of esophagus and improvement of quality. Method 11 cases of advanced carcinoma of esophagus were included in this study. Operation and chemical therapy were unavailable for these patients. Memory trestle with membrane and made of alloy of Nickel－ titanium was inserted under intervention of endoscope. Trestle was posed in stenosis part of esophagus under direction of X－ ray. Trestle could be dilated 3－ 7 days after operation due to its reaction characteristics to temperature. So, redilated therapy was unnecessary. Trestle could reconstruct swallowing tract and made feeding through mouth become available during limited survival time.Results All trestles were successfully inserted.Half－ fluid feeding was available after operation. Obstruction was removed in all patients(100％ ).Conclusion Method described in this study was safe and effective .Effective swallowing tracts were reconstructed in all patients after trestle was planted and quality of life and survival time were both improved.
