Squamous papilloma of the esophagus is a rare benign lesion of the esophagus. Radiofrequency ablation is an established endoscopic technique for the eradication of Barrett esophagus. No cases of endoscopic ablation of esophageal papilloma by radiofrequency ablation (RFA) have been reported. We report a case of esophageal papilloma successfully treated with a single session of radiofrequency ablation. Endoscopic ablation of the lesion was achieved by radiofrequency using a new catheter inserted through the working channel of endoscope. The esophageal ablated tissue was removed by a specifically designed cup. Complete ablation was confirmed at 3 mo by endoscopy with biopsies. This case supports feasibility and safety of as a new potential indication for BarrxTM RFA in patients with esophageal papilloma.
Core tip: This paper reports for the first time a flexible endoscopic treatment of esophageal papilloma by a new radiofrequency system that goes into the working channel of the endoscope. This allows the endoscopist to see what he is doing along the procedure and to complete the procedure in few minutes. The procedure was performed without particular difficulties and did not required elevated skills.
