Introduction. The heterotopic gastric mucosal patch or inlet patch is the presence of gastric columnar mucosa outside the stomach, most frequently located in the proximal esophagus. Its manifestations vary from esophageal and extraesophageal reflux symptoms to major complications, most of them being asymptomatic. Aim. To determine the prevalence of cervical heterotopic gastric mucosa in our environment and its association with esophageal and extraesophageal reflux symptoms. Material and methods. Prospective cross-sectional and observational study; consecutive patients who came to our institution between December 2018 and October 2019 for diagnostic upper gastrointestinal videoendoscopy were included, following a questionnaire on clinical manifestations. Results. A total of 1,408 patients were included. In 89 (6.3%), a cervical heterotopic gastric mucosal patch was described. The mean age of the patients without this condition was 54.6 and 55.5 in patients with it. The esophageal symptoms of gastroesophageal reflux (heartburn, regurgitation, and chest pain) in patients with cervical heterotopic gastric mucosa was observed in 40 (44.9% / p = 0.473), 12 (13.5% / p = 0.783) and 4 (4.5% / p = 0.199) patients respectively. The presence of extraesophageal symptoms (globus, chronic cough, dysphonia, and throat clearing) in patients with cervical heterotopic gastric mucosa was: 9 (10.1% / p = 0.011); 7 (7.9% / p = 0.155); 4 (4.5% / p = 0.458) and 9 (10.1% / p = 0.036) respectively. Conclusions. A statistically significant association was found between the presence of cervical heterotopic gastric mucosal patch and symptoms of globus (p = 0.011) and throat clearing (p = 0.036). It could be interpreted that this group of patients would benefit from the research and treatment of this condition with the intention of improving their symptoms.
