Since August 1984 18 patients suffering from inoperable esophageal cancer have been treated by Nd. Yag Laser therapy under endoscopic control in the Verona University Institute of Clinical Surgery. Three patients, all males ranging in age from 68 to 80 years, had endo-esophageal prostheses which were occluded as a result of the neoplasms. Occlusion of the prostheses had been ascertained by both x-rays and endoscopy. The symptoms consisted of severe dysphagia of solid foods in 2 cases and of solids and liquids in 1 case. The original sites of the tumors were the lower 3rd in two cases and the mid 3rd in 1 case. Histologically, the tumors were identified as 2 squamous-cell carcinomas and 1 adenocarcinoma. Laser treatment was given on average once every 7 days. Patients were admitted to the day hospital, thus avoiding negative repercussions in terms of quality of life or length of hospital stay. In 2 cases there was an improvement in symptoms with the possibility of semi-solid nutrition after a single treatment with 6000-5032 Joules. In the third case, to obtain the same result, 2 treatments were necessary at an interval of 7 days with a total of 9396 J. One patient died of cardiorespiratory failure 24 days after the first treatment. A second patient was treated a further 3 times with a total of 12356 J and is now on a liquid and solid diet 5 months after the first treatment. The third patient was treated 4 times with a total of 15769 J; this patient was on a liquid and solid diet, but died of cardiorespiratory failure 3 months after the first treatment. In the light of our experience, Nd. Yag Laser disocclusion of endo-esophageal prostheses occluded by neoplasms presented no complications and was an appropriate indication in these cases with satisfactory long-term results.

Abstract
Since August 1984 18 patients suffering from inoperable esophageal cancer have been treated by Nd. Yag Laser therapy under endoscopic control in the Verona University Institute of Clinical Surgery. Three patients, all males ranging in age from 68 to 80 years, had endo-esophageal prostheses which were occluded as a result of the neoplasms. Occlusion of the prostheses had been ascertained by both x-rays and endoscopy. The symptoms consisted of severe dysphagia of solid foods in 2 cases and of solids and liquids in 1 case. The original sites of the tumors were the lower 3rd in two cases and the mid 3rd in 1 case. Histologically, the tumors were identified as 2 squamous-cell carcinomas and 1 adenocarcinoma. Laser treatment was given on average once every 7 days. Patients were admitted to the day hospital, thus avoiding negative repercussions in terms of quality of life or length of hospital stay. In 2 cases there was an improvement in symptoms with the possibility of semi-solid nutrition after a single treatment with 6000-5032 Joules. In the third case, to obtain the same result, 2 treatments were necessary at an interval of 7 days with a total of 9396 J. One patient died of cardiorespiratory failure 24 days after the first treatment. A second patient was treated a further 3 times with a total of 12356 J and is now on a liquid and solid diet 5 months after the first treatment. The third patient was treated 4 times with a total of 15769 J; this patient was on a liquid and solid diet, but died of cardiorespiratory failure 3 months after the first treatment. In the light of our experience, Nd. Yag Laser disocclusion of endo-esophageal prostheses occluded by neoplasms presented no complications and was an appropriate indication in these cases with satisfactory long-term results.
