Int J Pediatr Otorhinolaryngol 2020; 138:110271. [PMID: 32805494 DOI: 10.1016/j.ijporl.2020.110271] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 07/20/2020] [Accepted: 07/21/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Despite a reported incidence of HGMPE of 10%, proof of acid production, and an increased incidence of respiratory symptoms, the pediatric otolaryngology, swallowing and voice care literature is silent on this entity. This case series describes pediatric patients confirmed to have HGMPE with dysphonia and/or dysphagia. METHODS Retrospective case series of Pediatric Voice, Resonance, and Swallowing Center patients at a tertiary Children's Hospital in 2019. SETTING Tertiary academic medical center. SUMMARY OF RESULTS Three patients who underwent triple endoscopy for dysphonia or dysphagia were histologically diagnosed with HGMPE. Esophageal biopsies were otherwise normal. Two of the three patients resolved their primary aerodigestive symptoms following treatment with acid suppression and a protectant (sucralfate). The third patient reported significant improvement in symptoms by phone. The significance of this case series cannot be understated: 1) A need for increased awareness among pediatric otolaryngologists, voice care and swallowing professionals of this entity given its relatively common incidence of 10% offset by a dearth of presentations & scientific publications in our literature clearly exists. 2) Otolaryngologists have abandoned operative upper aerodigestive tract endoscopy in lieu of office-based less comprehensive videolaryngostroboscopy and fiberoptic endoscopic evaluation of swallowing. HGMPE & other esophageal disorders (i.e. eosinophilic esophagitis) support revisiting triple endoscopy in select patients where office endoscopy has failed to diagnose and successfully treat such patients. 3) Both acid suppression therapy and a protectant (sucralfate) may be useful in these patients. 4) Modification of rigid esophagoscopy technique to carefully assess the introitus and superior esophageal segment is paramount 5) Otolaryngologists over-diagnose & over-treat laryngopharyngeal reflux. The pediatric & adult literature is replete with significant safety warnings associated with acid suppression therapy and guidelines admonish their indiscriminate use, raising the liability bar of empiric treatment. Large scale prospective, randomized and controlled studies are needed to confirm the pathophysiologic role of this entity in pediatric aerodigestive disorders. CONCLUSION HGMPE is a clinical entity that can be easily missed upon swift entry into the esophagus with rigid endoscopy. Careful scrutiny and visualization of the proximal esophagus is critical in order to identify HGMPE, as there is a higher rate of laryngospasm, stricture, and potentially neoplasm in this population.

Abstract
PURPOSE OF REVIEW The purpose of this review is to assess recent literature on the clinical relevance of the gastric inlet patch with particular focus on endoscopic diagnosis and treatment, the relationship of the inlet patch to laryngopharyngeal reflux disease and the association of proximal esophageal adenocarcinoma with inlet patch. RECENT FINDINGS Recent studies suggest endoscopic diagnosis of inlet patch increases with endoscopist awareness (up to 10-fold) and when using enhanced imaging techniques such as narrow band imaging (up to three-fold). The literature remains mixed on the association of inlet patch with laryngopharyngeal symptoms or globus sensation. Studies of endoscopic ablation, using argon plasma coagulation or radiofrequency ablation have shown improved laryngopharyngeal reflux symptom scores posttreatment. Proximal esophageal adenocarcinomas are rare but often associated with inlet patch when they occur. Case studies have described endoscopic resection of malignant lesions related to inlet patch, using endoscopic mucosal resection or submucosal dissection. SUMMARY Prospective, multicenter studies of symptom association with inlet patch using validated symptom questionnaires and blinded sham-controlled treatments are needed to further clarify the role of such treatments, which to date are limited to a small numbers of centers with a special interest.

Abstract
INTRODUCTION AND AIMS An inlet patch (IP) is the presence of gastric columnar epithelium outside of the stomach. No studies have been conducted in Mexico on that pathology. The aim of the present study was to determine the prevalence of esophageal IP and the clinical characteristics of the patients that present it. MATERIALS AND METHODS A cross-sectional study was conducted that included consecutive patients referred for endoscopy within the time frame of September 2015 to May 2016. The patients answered a questionnaire, and high-definition endoscopy with digital chromoendoscopy was performed. The prevalence of IP was identified. The chi-square test was used to compare the clinical characteristics between patients that presented with esophageal IP and those without it. RESULTS A total of 239 patients were included in the study. Their mean age was 53 years, and 130 (54.4%) were women. IP was found in 26 patients (10.9%), 15 of whom were men (57.7%). The main reason for referral to endoscopy was gastroesophageal reflux disease, present in 69.2% of the patients with IP and in 55.9% without IP (p=.19). The most common symptoms were heartburn and regurgitation. The former was present in 69.2% of the patients with IP and in 59.1% without IP (p=.32), and the latter was present in 65.4% of the patients with IP and 69.1% without IP (p=.7). Extraesophageal manifestation distribution was: cough in 46.2% of the patients with IP and 38% without IP (p=.45) and dysphonia in 54% with IP and 47% without IP (p=.53). Twenty-three percent of the patients with IP had Barrett's esophagus, as did 23% without IP (p=.99). CONCLUSIONS The prevalence of IP was high. The primary referral diagnosis was gastroesophageal reflux disease. No differences were found in relation to symptoms or the presence of Barrett's esophagus between the patients with and without IP.

Abstract
OBJECTIVES To determine the incidence of inlet patch (IP) and to assess the clinical and pathological features, role of the diagnostic workup in treatment decision making, efficacy of medical and endoscopic therapy, and natural history in a pediatric population. STUDY DESIGN Consecutive patients aged <18 years (n = 1000) undergoing esophagogastroduodenoscopy were enrolled prospectively. Biopsy specimens were obtained from IPs and the proximal and distal esophagus, stomach, and duodenum. Multichannel intraluminal impedance and pH monitoring (MII-pH) was performed in all symptomatic patients. Symptomatic patients were treated with proton pump inhibitors for 8 weeks, and IP ablation by argon plasma coagulation (APC) was performed in unresponsive patients. RESULTS The endoscopic incidence of IP was 6.3%, with a cumulative missing rate of 5.8%. Thirty-five of the 63 patients (56%) were asymptomatic, 11 (17%) had symptoms clearly related to the underlying digestive disorder, and 17 (27%) had chronic IP-related symptoms. MII-pH was positive in 10 of the 28 symptomatic patients. All 17 patients with IP-related symptoms were unresponsive to proton pump inhibitors and were treated with APC, and all had achieved complete remission by the 3-year follow-up. Patients with underlying disorders were successfully treated with medical therapy, and asymptomatic patients remained symptom-free, with no endoscopic or histological changes seen at the 3-year follow-up. CONCLUSION IP is an under-recognized cause of symptoms in children with unexplained esophageal and respiratory symptoms. MII-pH and bioptic sampling are needed to exclude entities mimicking IP symptoms and to direct therapy. APC is safe and effective for treating IP-related symptoms.

Abstract
Foci of heterotopic gastric mucosa have been identified at different sites in the human body and the most common location is the proximal esophagus which is referred to as cervical inlet patch (CIP). The true prevalence of CIP varies and it is usually incidental findings during endoscopy. Because CIP is always asymptomatic, it was believed to be of little clinical relevance. However, emerging studies have described the acid-secreting characteristics of heterotopic gastric mucosa and associations of CIP with gastroesophageal reflux disease (GERD). In addition, complications such as stricture, fistula, infection, mucosal hyperplasia, and malignant transformation have been reported. In this study, we investigated the prevalence of CIP, its associations with clinical manifestations, and the effect of intentional screening upper esophagus by magnifying endoscopy-narrow-band imaging (ME-NBI) system. Consecutive healthy adults who underwent panendoscopy were separated into two groups. Patients in group I (n = 471) were examined by an endoscopist who intended to find CIPs by ME-NBI. Patients in group II (n = 428) were examined by two endoscopists who were unaware of the study and performed white-light imaging endoscopy. Participants provided questionnaires on GERD-related symptoms. Higher CIP prevalence (11.7% vs. 1.9%, P < 0.0001) and longer duration of esophageal examination (mean ± standard deviation, 17.50 ± 12.40 vs. 15.24 ± 10.78 seconds, P = 0.004) were noted in group I than in group II. Analyzing group I patients revealed the higher prevalences of reflux symptoms (32.7% vs. 18.3%, P = 0.013) and erosive esophagitis (43.6% vs. 25.5%, P = 0.005) in patients with CIP than in those without. CIP was not associated with globus or dysphagia symptoms. More small CIPs (< 5 mm) were detected by ME-NBI than by white-light imaging (85.3% vs. 41.4%, P = 0.001). In conclusion, CIP prevalence was not low under intentional ME-NBI examination of the upper esophagus. The clinical relevance of CIP and its association with GERD require further investigation.

Abstract
Heterotopic gastric mucosa of the proximal esophagus (HGMPE), also referred to as “inlet patch” or “cervical inlet patch”, is a salmon colored patch that is usually located just distal to the upper esophageal sphincter. HGMPE is uncommon with endoscopic studies reporting a prevalence ranging from less than one percent to 18%. Most HGMPE are asymptomatic and are detected incidentally during endoscopy for evaluations of other gastrointestinal complaints. Most consider HGMPE as clinically irrelevant entity. The clinical significance of HGMPE is mainly acid related or neoplastic transformation. The reported prevalence of laryngopharyngeal reflux symptoms varies from less than 20% to as high as 73.1%. However, most of these symptoms are mild. Clinically significant acid related complications such as bleeding, ulcerations, structure and fistulization have been reported. Although rare, dysplastic changes and malignancies in association with HGMPE have also been reported. Associations with Barrett’s esophagus have also been reported but the findings so far have been conflicting. There are still many areas that are unknown or not well understood and these include the natural history of HGMPE, risk factors for complications, role of Helicobacter pylori infection and factors associated with malignant transformations. Follow-up may need to be considered for patients with complications of HGMPE and surveillance if biopsies show intestinal metaplasia or dysplastic changes. Despite the overall low incidence of clinically relevant manifestations reported in the literature, HGMPE is a clinically significant entity but further researches are required to better understand its clinical significance.
