Endoscopic placement of an esophageal endoprosthesis is the most rational therapy for relieving the distress of malignant esophago-pulmonary fistula. The commercial prostheses are very expensive for widespread use in India. We have indigenously prepared silicone rubber endoprostheses. The wall of the prosthesis was hardened in a graded manner until the desired resistance to compression with flexibility is achieved. This prosthesis was placed successfully in five patients with malignant esophago-pulmonary fistula. Dysphagia and aspiration were relieved in all the patients. One patient had delayed esophageal perforation and died of massive bleeding 3 weeks after the placement of prosthesis. The indigenous endoprosthesis is cost-effective and safe.
