Overview
Introduction: Heterotopic gastric mucosa of the proximal esophagus (IP – inlet patch) is an islet of gastric mucosa close to the upper esophageal sfincter. Its cells may be able to produce acids and digestive enzymes. Methodology: Prospective study from 2020–2021 follows patients of groups A and B who underwent gastroduodenal endoscopic procedure or direct esophagoscopy in general anesthesia. In group C, patients with confirmed inlet patch underwent ENT videoendoscopic procedure to asses any laryngeal mucosa damage. Results: The prevalence of IP in our group was determined to be 4.87%. We diagnosed 40 IPs out of 821 examinations performed. Group C does not show any signs of laryngeal mucosal damage in patients with inlet patch. Conclusion: The prevalence of IP in the Nový Jičín region was 4.87%. In our study group, we didn’t find any significant laryngeal mucosal damage in patients with IP. t is necessary to think about IP in patients with laryngopharyngeal reflux without the effect of conservative therapy as a possible cause of difficulties. In the treatment of extraoesophageal reflux, which is difficult to influence with conservative therapy, it is advisable to supplement the gastrofibroscopic examination with a focus on the evidence of IP and its biopsy.
