Frequently when dysphagia first becomes manifest, esophageal carcinoma is already unresectable. Endoscopic laser therapy is a recently introduced method which can be used for the palliative treatment of esophageal cancer. By using the method the tumour is destroyed and the esophagus is recanalized, there is low incidence of complications, and the patient can be fed naturally thus improving quality of life. The method has been perfected over the past years and now offers excellent results.
