Radiofrequency ablation of symptomatic cervical inlet patch using a through-the-scope device: a pilot study.

Background And Aims: The cervical inlet patch (CIP) is an area of heterotopic gastric mucosa at the proximal esophagus, which can secrete both acid and mucus. Attributable symptoms include chronic globus sensation and sore throat. Previous studies have demonstrated improvement in symptoms after ablation using argon plasma coagulation.
