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.

| Measure | Description | Time Frame |
|---|---|---|
| Complete histologic eradication of heterotopic gastric mucosa | the change from gastric epithelium to squamous epithelium is monitored by histological sampling throughout the study period | measured endoscopically throughout the study period. First time point of measurement is 3 months after first ablation. Further measurements are carried out 3 months after subsequent ablations up to a maximum number of three ablations. |
| Measure | Description | Time Frame |
|---|---|---|
| symptom assessment | visual analog scale 0-10 (0=no interference, 10=maximum interference) is used for the symptom assessment of globus sensation | measured at the beginning, 12 weeks after first ablation and 12 weeks after final endoscopic examination |
| laryngopharyngeal reflux |
