Recurrent oesophageal intramucosal squamous carcinoma treated by endoscopic mucosal resection and subsequent radiofrequency ablation using HALO system.

The method of radiofrequency ablation (RFA) is currently used for the treatment of high-grade dysplasia in Barrett's oesophagus. It has theoretical potential also for the use in squamous epithelial neoplasias. The authors present a case report of an early diagnosis of squamous cancer in a high-risk patient, its endoscopic treatment and follow-up, and successful RFA of recurrent neoplasia. RFA can expand our therapeutic possibilities for the management of recurrent neoplastic lesions after endoscopic treatment of squamous oesophageal cancer.
