  • Title: Heterotopic gastric mucosal patch in patients with reflux laryngitis: an entity of clinical interest?
    Author: Salminen P, Ovaska J.
    Journal: Surg Laparosc Endosc Percutan Tech; 2009 Oct; 19(5):361-3. PubMed ID: 19851260.
    Abstract:
    Heterotopic gastric mucosal patch (HGMP) in the upper esophagus has been suggested to play a role in the pathogenesis of laryngopharyngeal reflux. The aim of this study was to evaluate the prevalence and possible clinical significance of HGMPs in patients who underwent laparoscopic Nissen fundoplication for gastroesophageal reflux disease-induced reflux laryngitis.Forty consecutive patients with pH-proven reflux laryngitis referred to surgery by a specialist in otorhinolaryngology underwent laparoscopic Nissen fundoplication between 1998 and 2002. Twenty-seven (67.5%) of these patients underwent a postoperative upper gastrointestinal endoscopy paying special attention for detecting possible HGMPs in the proximal esophagus. When HGMP was found, biopsies were taken for histologic confirmation. A small histologically confirmed HGMP was detected in 1 out of 27 patients (3.7%). The prevalence of HGMPs in the upper esophagus in this specific patient group operated on for gastroesophageal reflux disease-induced reflux laryngitis equals the reported general prevalence rates of HGMPs detected in patients referred for upper gastrointestinal endoscopy as a part of gastrointestinal tract evaluation. The role of at least small HGMPs in the proximal esophagus in the pathogenesis of laryngopharyngeal reflux is clinically insignificant.
