[Chromoendoscopy in the diagnosis of precancerous lesions of the esophagus. Our experience].
The elements of an unfavourable prognosis for oesophageal cancer are frequent metastasis, high incidence of local recurrence and mainly the difficulty of an early diagnosis. Alcohol, tobacco and precancerous lesions are the most important risk factors of these tumours. According to literature, the authors suggest the method of chromoendoscopy, with vital staining by lugol or blue toluidine for endoscopic; guidance to biopsy in the aimed screening of patients, whose habits--alcohol, smoking--should cause, in time, the rising of lesions with neoplastic potentiality. Endoscopy with bioptic test is the best diagnostic investigation. In fact sensibility and specificity of these investigations increase using this method with vital staining.
