Endoscopic Therapy of Early Carcinoma of the Oesophagus

BACKGROUND Oesophageal cancer is a comparatively rare disease in the Western world. Prognosis is highly dependent on the choice of treatment. Early stages can be treated by endoscopic resection, whereas surgery needs to be performed in the case of advanced carcinomas. Technical progress has enabled high-definition endoscopes and technical add-ons which help the endoscopist in finding fine irregularities in the oesophageal mucosa, though interpretation still remains challenging. METHODS In this review, we discuss both novel and old diagnostic procedures and their value, as well as the current recommendations for the diagnosis and treatment of early oesophageal carcinomas. The database of PubMed and Medline was searched and analysed to provide all relevant literature for this review. RESULTS AND CONCLUSION Endoscopic resection is the therapy of choice in early oesophageal cancer. In case of adenocarcinoma it is mandatory to perform subsequent ablation of all residual Barrett's mucosa to avoid metachronous lesions.
