Symptomatic heterotopic gastric mucosa also known as cervical inlet patch (CIP) may be
present in varying shapes and causes symptoms of laryngopharyngeal reflux like globus
sensations, hoarseness and chronic cough. Unfortunately, argon plasma coagulation, standard
treatment of small symptomatic CIP, is limited for large heterotopic gastric mucosa due to
concerns of stricture formation. Therefore, the investigators aimed to investigate the effect
of radiofrequency ablation (RFA), a novel minimal-invasive ablation method, in the treatment
of large symptomatic CIP.
