Abstract
BACKGROUND Heterotopic gastric mucosa in the upper esophagus (HGMUE) is considered to be accompanied by pharyngolaryngeal symptoms, whereas the association strength between HGMUE and pharyngolaryngeal symptoms remains controversial. This study assessed the strength of the association between HGMUE and pharyngolaryngeal symptoms using a meta-analytic approach. METHODS PubMed, Embase, Web of Science, and CNKI databases were searched for relevant articles published between January 2010 and January 2024. The pharyngolaryngeal symptoms of chronic cough, dysphagia, hoarseness, and globus in patients with HGMUE were summarized. The pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using a random-effects model. The exploratory analyses were also performed, including sensitivity and subgroup analyses. RESULTS A total of 17 observational studies (1 cohort study and 16 cross-sectional studies) with 626,369 patients (2414 HGMUE patients and 623,955 non-HGMUE patients) were included in the meta-analysis. HGMUE was significantly associated with an elevated incidence of chronic cough (OR: 3.36; 95% CI 1.25-9.01; P = 0.02), dysphagia (OR: 1.58; 95% CI 1.12-2.25; P = 0.01), hoarseness (OR: 4.13; 95% CI 1.47-11.56; P = 0.007), and globus (OR: 2.41; 95% CI: 1.43-4.04, P < 0.001). The association between HGMUE and the risk of dysphagia was found to be potentially influenced by study design, sample size, country, and diagnostic method, whereas the association between HGMUE with the risk of globus was potentially affected by the study design and country. CONCLUSION HGMUE was significantly associated with chronic cough, dysphagia, hoarseness, and globus. HGMUE should be taken into consideration for patients with pharyngolaryngeal symptoms.

Abstract
INTRODUCTION Gastric inlet patches are often incidental, but can also be a treatable cause of laryngo-esophageal symptoms. METHODS We retrospectively reviewed all patients whose gastric inlet patches were diagnosed following assessment for laryngopharyngeal and swallowing symptoms. Improvement following Argon Plasma Coagulation (APC) was assessed using Minimum Clinically-Important Difference methodology combining voice, throat, and swallowing domains. Correlations between APC response and measures of reflux and mucosal barrier integrity, measured during 24-h pH-impedance manometry, were obtained. Proximal and Distal Mean Nocturnal Baseline Impedance (MNBI) values were separately calculated and the novel variable of Mucosal Impedance Gradient was derived as [((Distal MNBI-Proximal MNBI)/((Distal MNBI + Proximal MMBI)/2)) x 100]. KEY RESULTS Inlet patches were detected in 57 of 651 patients who had Transnasal Panendoscopy (8.7 ± 2.2%). There were 34 males. Mean age was 58 years. Mean duration of symptoms was 2 years. The commonest symptoms were hoarseness (n = 33), throat symptoms (n = 24), and dysphagia (n = 21), respectively. APC was used to ablate patches in 34 patients. Treatment response was 71% at a mean followup of 5.5 months. MIG > - 25% predicted response to APC, with area under the receiver operating characteristic curve of 0.875 (Sensitivity = 81%; Specificity = 100%; p < 0.0001). CONCLUSIONS Gastric inlet patches are common and under-recognized. They can cause protracted pharyngo-esophageal symptoms. Patch ablation is an effective treatment for carefully selected patients. Optimal patient selection requires multidisciplinary teamwork. Mucosal Impedance Gradient could further refine patient selection.

Abstract
Cervical inlet patches (CIP) are common endoscopic findings with uncertain pathogenesis and clinical significance. We aimed to perform a systematic review and prospective study of clinical data and endoscopic findings related to CIP. It was a prospective single-center study conducted between 10/01/2017 and 9/01/2018. Forty patients with histopathologically confirmed CIP were compared with 222 individuals in the reference group. The systematic review was executed in accordance with the PRISMA guideline. Alcohol consumption tended to be higher among patients with CIP (3.0 ± 4.6 vs. 1.9 ± 5.0 standard drinks/week CIP patients and reference group, respectively; p < 0.001). Dysphagia was more frequent among patients with CIP (25% vs. 1.4%, CIP patients and reference group, respectively; p < 0.001), and sore throat and hoarseness were less frequent in patients with CIP (17.5% vs. 26.6% CIP patients and reference group, respectively; p < 0.01). In the multivariate regression analysis, the only risk factor of CIP occurrence was dysphagia (OR 21.9, 95%CI 4.9-98.6; p < 0.001). Sore throat and hoarseness were a reverse-risk factor of CIP diagnosis (OR 0.3, 95%CI 0.1-0.93; p = 0.04). Clinical data and coexisting endoscopic findings were not related to CIP. In the presented study, dysphagia was related to CIP occurrence, and sore throat and hoarseness tended to be less frequent among patients with CIP.

CHILDREN (BASEL, SWITZERLAND) 2023; 10:children10020229. [PMID: 36832358 PMCID: PMC9955082 DOI: 10.3390/children10020229] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/04/2022] [Revised: 01/23/2023] [Accepted: 01/26/2023] [Indexed: 01/31/2023]
Abstract
Helicobacter pylori infection is one of the main causes of dyspepsia, but it is not the only cause. Esophageal inlet patches are areas of heterotopic gastric mucosa within the esophagus and are commonly located in the cervical part of the esophagus. We report the case of a 16-year-old female, previously known to display symptoms of anxiety, who was admitted to our clinic for dyspeptic symptoms lasting for approximately 1 month in spite of the treatment with proton pump inhibitors. The clinical exam revealed only abdominal tenderness in the epigastric area, while routine laboratory tests showed no abnormalities. The upper digestive endoscopy revealed a well-circumscribed salmon-pink-colored oval lesion of approximately 10 mm in the cervical esophagus, along with hyperemia of the gastric mucosa and biliary reflux. The histopathological exam established the diagnosis of esophageal inlet patch with heterotopic antral-type gastric mucosa and also revealed regenerative changes within the gastric mucosa. We continued to treat the patient with proton pump inhibitors, as well as ursodeoxycholic acid, with favorable evolution. Although rare or underdiagnosed, esophageal inlet patches should never be underestimated and all gastroenterologists should be aware of their presence when performing an upper digestive examination in a patient with dyspeptic symptoms.

Abstract
Objective The goal of this study was to characterize the symptoms and outcomes of patients with a symptomatic cervical inlet patch (CIP). Study Design Retrospective case series. Setting Tertiary care laryngology clinic in Charlottesville, Virginia. Methods A retrospective chart review of the patient's demographics, comorbidities, prior workup, interventions, and response to treatment was performed. All patients received flexible nasolaryngoscopy and barium swallow study. The analysis was descriptive. Results Eight patients (6 female) were followed for the management of symptoms related to CIP. The mean age at presentation to our clinic was 64.9 (standard deviation = 15.7). Five out of 8 patients presented with a chief complaint of dysphagia, and the remaining 3 with chronic coughs. Five out of 8 patients demonstrated findings of laryngopharyngeal reflux (LPR) including vocal fold edema, mucosal erythema, or postcricoid edema. Swallow study demonstrated hiatal hernia in 3 of 8 patients, and cricopharyngeal (CP) dysfunction (CP hypertrophy, CP bar, and Zenker's diverticulum) in 3 of 8 patients. One patient presented with a history of Barrett's esophagus. Treatment included increased acid suppression therapy and management of coexisting esophageal pathologies. Ablative procedures were performed in 5 out of 8 cases, with 2 patients requiring repeat procedures. All patients experience subjective symptom improvement. Conclusion CIP tends to present in complex patients with multifactorial dysphagia, with the most common symptoms being dysphagia and cough. Clinical features of CIP overlap with other more common pathologies encountered by otolaryngologists including LPR and CP dysfunction, and future prospective studies in larger populations should seek to clarify these associations.

Abstract
Esophageal heterotopic gastric mucosal patches (HGMP), also known as cervical inlet patches (CIP), is a rare but underdiagnosed condition characterized by the presence of salmon-colored, velvety mucosa located in the proximal esophagus, distal to the upper esophageal sphincter. The incidence of CIP ranges from 3% to 10% in adults, and its endoscopic appearance is characterized by a flat or slightly raised salmon-colored patch. In this case, we report a 78-year-old man who presented with symptoms of laryngopharyngeal reflux and dysphagia. An esophagogastroduodenoscopy showed a flat area of salmon-colored patch between 17 and 20 cm from the incisors, suggestive of a CIP complicated by stricture. The biopsy results showed an oxyntic-type mucosa lined with columnar cells consistent with an inlet patch. Esophageal dilation was done with a savory dilator with no resistance at 18 mm. The patient was placed on maintenance acid suppression therapy with proton-pump inhibitors and reported complete resolution of symptoms at the 1-month follow-up.

Abstract
Ectopic gastric mucosa can be present throughout the gastrointestinal tract; however, when located within the upper esophagus, it is termed an esophageal inlet patch. To the best of our knowledge, most esophageal inlet patches occur as a single area of gastric mucosa. Here, we present a 44-year-old female who suffered from symptoms of chronic dysphagia and globus sensation for two years due to multiple inlet patches located in the cervical area of the upper esophagus with an associated cervical esophageal stricture. The patient underwent esophageal dilation and proton pump inhibitor therapy, resulting in a resolution of her symptoms. Our case demonstrates the appropriate clinical management of patients suffering from symptoms of chronic dysphagia due to multiple esophageal inlet patches. We recommend routine examination of the cervical esophagus in developing a differential diagnosis of inlet patch, especially in patients with chronic upper dysphagia.

Abstract
OBJECTIVES Argon plasma coagulation (APC) of gastric inlet patches of the cervical esophagus (GIP) has been shown to relieve the globus sensation. This study aimed to investigate the long-term effects of APC therapy on a variety of laryngopharyngeal symptoms. METHODS Patients with laryngopharyngeal symptoms who had undergone endoscopic GIP eradication via APC therapy were eligible for a retrospective observational cohort study. Symptom relief was assessed by a five-grade scale during a structured interview. Statistical analysis included ANOVA, the chi-squared and t-test. RESULTS A total of 45 patients (61.0 (52.0; 69.0) years, 26 (57.8%) female) were included after a follow-up time of 85.0 (55.3; 111.0) months. Symptoms included dysphagia (56.0%), dysphonia (51.0%), hoarseness (76.0%), the necessity of throat clearing (73.0%), globus sensation (56.0%) and heartburn (71.0%). Complete GIP eradication was achieved after one session in 25 (55.6%), repetitive sessions were needed in the remaining cases. Fourteen patients (31.1%) reported a very strong, 11 (24.4%) a strong and 8 patients (17.8%) an intermediate improvement; five patients did not benefit. The most apparent improvement was seen regarding hoarseness (from 2.6 ± 1.7 to 1.2 ± 1.3), the necessity of throat clearing (from 2.6 ± 1.7 to 1.1 ± 1.3), globus sensation (from 2.0 ± 1.9 to 0.9 ± 1.3) and heartburn (from 2.5 ± 1.8 to 1.4 ± 1.6). Adverse events included post-endoscopic pain (n = 6, 13.3%) and purulent pharyngitis (n = 2, 4.4%). CONCLUSIONS The APC therapy of GIP is safe and leads to long-term relief of laryngopharyngeal symptoms in carefully selected patients.

Abstract
BACKGROUND Cervical inlet patch (CIP), also called gastric inlet patch, is a heterotopic columnar mucosal island located in the cervical esophagus, which has been under-recognized by clinicians. AIM We conducted a systemic review and meta-analysis to explore the prevalence and clinical and endoscopic characteristics of CIP. MATERIALS AND METHODS Studies were searched through the PubMed, EMBASE, and Cochrane Library databases. The prevalence of CIP with 95% confidence interval (CI) was pooled by using a random-effect model. The association of CIP with demographics, clinical presentations, and endoscopic features was evaluated by odds ratios (ORs). RESULTS Fifty-three studies including 932,777 patients were eligible. The pooled prevalence of CIP was 3.32% (95% CI=2.86%-3.82%). According to the endoscopic mode, the pooled prevalence of CIP was higher in studies using narrow-band imaging than in those using white light and esophageal capsule endoscopy (9.34% vs. 2.88% and 0.65%). The pooled prevalence of CIP was higher in studies where the endoscopists paid specific attention to the detection of this lesion (5.30% vs. 0.75%). CIP was significantly associated with male (OR=1.24, 95% CI=1.09-1.42, P=0.001), gastroesophageal reflux disease (OR=1.32, 95% CI=1.04-1.68, P=0.03), reflux symptoms (OR=1.44, 95% CI=1.14-1.83, P=0.002), dysphagia (OR=1.88, 95% CI=1.28-2.77, P=0.001), throat discomfort (OR=4.58, 95% CI=1.00-21.02, P=0.05), globus (OR=2.95, 95% CI=1.52-5.73, P=0.001), hoarseness (OR=4.32, 95% CI=1.91-9.78, P=0.0004), cough (OR=3.48, 95% CI=1.13-10.72, P=0.03), Barrett's esophagus (OR=2.01, 95% CI=1.37-2.94, P=0.0003), and esophagitis (OR=1.62, 95% CI=1.27-2.07, P=0.0001). CONCLUSION CIP appears to be common by using narrow-band imaging, especially if the endoscopists would like to pay attention to the detection of this lesion. CIP is clearly associated with acid-related symptoms and Barrett's esophagus.

Abstract
BACKGROUND The use of placebo comparisons for randomised trials assessing the efficacy of surgical interventions is increasingly being considered. However, a placebo control is a complex type of comparison group in the surgical setting and, although powerful, presents many challenges. OBJECTIVES To provide a summary of knowledge on placebo controls in surgical trials and to summarise any recommendations for designers, evaluators and funders of placebo-controlled surgical trials. DESIGN To carry out a state-of-the-art workshop and produce a corresponding report involving key stakeholders throughout. SETTING A workshop to discuss and summarise the existing knowledge and to develop the new guidelines. RESULTS To assess what a placebo control entails and to assess the understanding of this tool in the context of surgery is considered, along with when placebo controls in surgery are acceptable (and when they are desirable). We have considered ethics arguments and regulatory requirements, how a placebo control should be designed, how to identify and mitigate risk for participants in these trials, and how such trials should be carried out and interpreted. The use of placebo controls is justified in randomised controlled trials of surgical interventions provided that there is a strong scientific and ethics rationale. Surgical placebos might be most appropriate when there is poor evidence for the efficacy of the procedure and a justified concern that results of a trial would be associated with a high risk of bias, particularly because of the placebo effect. CONCLUSIONS The use of placebo controls is justified in randomised controlled trials of surgical interventions provided that there is a strong scientific and ethics rationale. Feasibility work is recommended to optimise the design and implementation of randomised controlled trials. An outline for best practice was produced in the form of the Applying Surgical Placebo in Randomised Evaluations (ASPIRE) guidelines for those considering the use of a placebo control in a surgical randomised controlled trial. LIMITATIONS Although the workshop participants involved international members, the majority of participants were from the UK. Therefore, although every attempt was made to make the recommendations applicable to all health systems, the guidelines may, unconsciously, be particularly applicable to clinical practice in the UK NHS. FUTURE WORK Future work should evaluate the use of the ASPIRE guidelines in making decisions about the use of a placebo-controlled surgical trial. In addition, further work is required on the appropriate nomenclature to adopt in this space.

Abstract
Globus is a non-painful sensation of a tightness or a lump/foreign body in the throat that is not associated with dysphagia and may actually improve during meals. While several otorhinolaryngologic, thyroid, and esophageal disorders have been linked to globus, cause-and-effect relationships are difficult to establish. Consequently, though part of the evaluation, objective otorhinolaryngologic and esophageal testing is often negative. The presence of alarm symptoms, particularly pain, weight loss, dysphagia, or odynophagia is indications for objective testing. A diagnosis of idiopathic globus requires exclusion of pharyngeal, laryngeal, and esophageal disorders with laryngoscopy, endoscopy, high-resolution manometry, barium radiography, and/or ambulatory reflux monitoring. A trial of acid-suppressive therapy may be reasonable in the absence of alarm symptoms, especially if concurrent reflux symptoms are identified. Ablation of heterotopic gastric mucosa in the proximal esophagus has been reported to improve globus symptoms. Beyond these specific approaches, further management of idiopathic globus consists of reassurance, neuromodulators, and complementary approaches. Globus has a benign course with no long-term consequences, and the overall prognosis is good as the magnitude of symptoms may decline over time.

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
The proximal esophagus is rarely examined, and its inspection is often inadequate. Optical chromoendoscopy techniques such as narrow band imaging improve the detection rate of inlet patches in the proximal esophagus, a region in which their prevalence is likely underestimated. Various studies have reported correlations between these esophageal marks with different issues such as Barrett's esophagus, but these findings remain controversial. Conflicting reports complicate the process of interpreting the clinical features of esophageal inlet patches and underestimate their importance. Unfortunately, the limited clinical data and statistical analyses make reaching any conclusions difficult. It is hypothesized that inlet patches are correlated with various esophageal and extraesophageal symptoms, diagnoses and the personalized therapeutic management of patients with inlet patches as well as the differential diagnosis for premalignant lesions or early cancers. Due to its potential underdiagnosis, there are no consensus guidelines for the management and follow up of inlet patches. This review focuses on questions that were raised from published literature on esophageal inlet patches in adults.

Abstract
Globus is an area of interest for many medical specialists including otorhinolaryngologists, gastroenterologist, allergists, and psychiatrists. It may be caused by an organic disease, but it is not uncommon that an underlying etiology remains unidentified even after a full workup has been performed. Patients who suffer from globus usually visit several physicians from different specialties without finding a solution for their symptoms. Identifying the underlying cause of globus is not always a simple task; therefore, structural or functional abnormalities of the thyroid, larynx, pharynx, and esophagus should be investigated. Gastroesophageal reflux disease is commonly considered to be the underlying cause after being identified in an otorhinolarygeal (ear, nose, and throat) evaluation, which is usually the first diagnostic step. In the last few years, an inlet patch in the proximal esophagus has been shown to be associated with globus, and its elimination has resulted in symptom resolution in some patients. Finally, globus can be associated with psychiatric disorders as well as oropharyngeal hypersensitivity that could be either chemical or mechanical. Treatment is directed toward an identified organic cause; in those with a functional disorder, the mainstay of therapy includes neuromodulators and psychiatric/psychological interventions.

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
The cervical inlet patch is an island of heterotopic gastric mucosa, most commonly found in the proximal oesophagus. Its importance as a cause of throat symptoms has been recognised, particularly chronic globus sensation. This has led to a change in the Rome IV criteria for globus management, with emphasis on ruling out the condition. Proton pump inhibitors are often ineffective in resolving symptoms. Endoscopic studies on the use of ablative techniques, most recently radiofrequency ablation (RFA), have shown promise in reversing the CIP to mormal squamous mucosa, with subsequent symtpomatic resolution. The aim of this review is to update on the investigation and management of the CIP.

Abstract
A woman aged 47 years reported the feeling of a lump in her throat for the past year. The sensation was present intermittently and usually improved when she ate. She noted it was worse with dry swallows when she felt like a tablet was stuck in her throat. The sensation had become more persistent in recent weeks leading her to worry that she had cancer. She had no cough, sore throat or hoarseness. There were no precipitating factors and no symptoms of weight loss, dysphagia, odynophagia or change in her voice. She had smoked previously and rarely had heartburn. She had no other anxieties and was not under any unusual stress. She was initially assessed by an ear, nose and throat surgeon, who found no abnormalities on examination of her neck, throat and oral cavity. Nasolaryngoscopy was normal. An upper gastrointestinal endoscopy was organised and reported a hiatus hernia, but a 3-month trial of a proton pump inhibitor did not have any impact on her symptoms. The benign nature of her symptoms was discussed at her gastroenterology follow-up appointment. She was discharged back to primary care with a final diagnosis of 'globus'. A trial of speech therapy, cognitive behavioural therapy or amitriptyline would be recommended if her symptoms became more troublesome in future.

Abstract
BACKGROUND AND AIM Symptomatic cervical heterotopic gastric mucosa, also known as cervical inlet patch (CIP), may present in various shapes and causes laryngopharyngeal reflux (LPR). Unfortunately, argon plasma coagulation, standard treatment of small symptomatic CIP, is limited in large CIP mainly because of concerns of stricture formation. Therefore, we aimed to investigate radiofrequency ablation (RFA), a novel minimally invasive ablation method, in the treatment of CIP focusing on large symptomatic patches. METHODS Consecutive patients with macroscopic and histological evidence of large (≥20 mm diameter) heterotopic gastric mucosa were included in this prospective trial. Primary outcome was complete macroscopic and histological eradication rate of CIP. Secondary outcome measures were symptom improvement, quality of life, severity of LPR and adverse events. RESULTS Ten patients (females, n = 5) underwent RFA of symptomatic CIP. Complete histological and macroscopic eradication of CIP was observed in 80% (females, n = 4) of individuals after two ablations. Globus sensations significantly improved from median visual analog scale score 8 (5-9) at baseline to 1.5 (1-7) after first ablation and 1 (1-2) after final evaluation (P < 0.001). Mental health scores significantly increased from 41.4 (± 8.5) to 54.4 (± 4.4) after RFA (P = 0.007). LPR improved significantly (P = 0.005) with absence of strictures after a mean follow up of 1.9 (± 0.5) years. CONCLUSIONS This is the first study on RFA focusing on therapy of large symptomatic heterotopic gastric mucosa. Hereby, we demonstrate that this new technique can be successfully implemented in patients where treatment was limited so far (NCT03023280).

Abstract
BACKGROUND AND AIMS Sham procedures in endoscopy are used with the intention of controlling for placebo response, potentially allowing more precise evaluation of treatment effect. Nevertheless, this type of study may impose significant risk without potential benefit for those in the sham group. The aim of the current study was to systematically review and analyze the endoscopic literature to assess the safety of sham controls. METHODS MEDLINE and Embase databases were searched for endoscopic sham procedures for all dates to July 2017. Only randomized controlled trials comparing an endoscopic therapy with a sham were included. Primary outcome was adverse events (AEs) categorized as mild, moderate, or severe. Results were combined using a random-effects model. Heterogeneity was assessed with the I2 statistic, and publication bias was assessed with the Egger test and funnel plots. RESULTS Data were extracted from 34 publications (1987-2017; 100% full text), with a total of 2492 procedures (1355 treatment/1137 sham). Sham procedures involved upper endoscopy (31 studies) and ERCP (3 studies). Treatment arms included procedures with the following indications: weight loss (38.2%), GI bleeding (26.5%), GERD (20.6%), sphincter of Oddi dysfunction (8.8%), and dysphagia (6.2%). Overall percentage of severe adverse events (SAEs) in the sham group was 1.7% (19/1137). Of these, the most common SAEs in the sham groups were need for surgery/intensive care unit stay (35.3%), post-ERCP pancreatitis (23.5%), and perforation (11.8%). There was no significant difference in the odds of developing an SAE between the treatment group and the sham group (odds ratio, 1.3; 95% confidence interval [CI], 0.7-2.3). The pooled additional risk incurred from being initially randomized to the sham arm and then receiving a cross-over intervention was significant (RR, 1.33; 95% CI, 1.14-1.56; P < .001), compared with patients initially randomized to the study intervention. CONCLUSION The frequency of AEs in endoscopic sham procedures is substantial, and patients are subjected to considerable morbidity. These results raise a serious ethical dilemma regarding the use of sham-controlled trials.

Abstract
Cervical inlet patch (CIP), also referred to as esophageal heterotopic gastric mucosa, is regarded as the residue of columnar epithelium of the embryonic esophagus. Narrow band imaging increases the detection rate of CIP. Herein, we present a 55-year-old man with symptomatic circumferential inlet patch. He exhibited globus and dysphagia, and esophagogastroduodenoscopy found cir-cumferential CIP, where im-munohistochemistry revealed the existence of pro-ton pumps (H+, K+-ATPase). His throat symptoms were relieved by acid suppressive therapy with pump inhibitors. This case indicated that CIP should be considered as a differential diagnosis for the cause of globus symptoms in rare cases.

Abstract
This document represents the first position statement produced by the British Society of Gastroenterology and Association of Upper Gastrointestinal Surgeons of Great Britain and Ireland, setting out the minimum expected standards in diagnostic upper gastrointestinal endoscopy. The need for this statement has arisen from the recognition that while technical competence can be rapidly acquired, in practice the performance of a high-quality examination is variable, with an unacceptably high rate of failure to diagnose cancer at endoscopy. The importance of detecting early neoplasia has taken on greater significance in this era of minimally invasive, organ-preserving endoscopic therapy. In this position statement we describe 38 recommendations to improve diagnostic endoscopy quality. Our goal is to emphasise practices that encourage mucosal inspection and lesion recognition, with the aim of optimising the early diagnosis of upper gastrointestinal disease and improving patient outcomes.

Abstract
BACKGROUND AND AIMS The cervical inlet patch (CIP) is an area of heterotopic gastric mucosa at the proximal esophagus, which can secrete both acid and mucus. Attributable symptoms include chronic globus sensation and sore throat. Previous studies have demonstrated improvement in symptoms after ablation using argon plasma coagulation. Our aim was to assess a through-the-scope radiofrequency ablation (RFA) catheter for ablation of symptomatic CIP. METHODS Ten patients with endoscopically and histologically proven CIP and symptoms of globus or sore throat were included in the study. An ablation protocol of 3 ablations at 12 J/cm2, without removal of coagulated tissue between ablations, was used. A maximum of 2 RFA sessions, 3 months apart, was allowed. A visual analog score was completed at baseline, 6 weeks (on proton pump inhibitor), 3 months (off proton pump inhibitor), and 12 months after treatment. RESULTS Mean patient age was 56 years (±3 years, standard error of the mean), 60% were men, and 80% were white. Barrett's esophagus was present in 50%. The mean number of CIPs was 2 (range, 1-4) with a median surface area of 2 cm2 (range, .5-14). After a median of 2 treatments, 80% achieved complete endoscopic and histologic resolution, with a mean follow-up of 14 months (range, 12-17). Globus, sore throat, and cough significantly improved from baseline (P < .05). No strictures or buried glands were identified. CONCLUSIONS This prospective pilot study demonstrates that RFA using a through-the-scope device is safe and effective for treating patients with symptomatic CIP. One-year follow-up data suggest the effect is durable.

Abstract
OBJECTIVE Sham surgery (placebo surgery) is an intervention that omits the step thought to be therapeutically necessary. In surgical clinical trials, sham surgery serves an analogous purpose to placebo drugs, neutralizing biases such as the placebo effect. A critical review was performed to study the statistical relevance of the clinical trials about sham surgery in the light of potential confounding factors. MATERIALS AND METHODS For the critical review 52 articles were included. The possible confounding factors have been studied using a structured interpretative research form designed by the authors. This form includes the following ten confounding factors: I), lack of homogeneity among inclusion/exclusion criteria. II), false double blind. III), lack of post-surgery double blind. IV), power of the study. V), sample characteristics. VI), lost patients to Follow-up. VII), gender distribution. VIII), age equilibrium. IX), lack of psychological patient evaluation. X), lack of psychiatric patient evaluation. In most of the studies, at least one confounding factor was present. RESULTS The analysis of the confounding factors showed that they could influence the reliability of the surgical placebo effects. CONCLUSIONS The validity of sham surgery should be reconsidered.

Abstract
The landscape for patients with Barrett's oesophagus (BE) has changed significantly in the last decade. Research and new guidelines have helped gastroenterologists to better identify those patients with BE who are particularly at risk of developing oesophageal adenocarcinoma. In parallel, developments in endoscopic image enhancement technology and optical biopsy techniques have improved our ability to detect high-risk lesions. Once these lesions have been identified, the improvements in minimally invasive endoscopic therapies has meant that these patients can potentially be cured of early cancer and high-risk dysplastic lesions without the need for surgery, which still has a significant morbidity and mortality. The importance of reaching an accurate diagnosis of BE remains of paramount importance. More work is needed, however. The vast majority of those undergoing surveillance for their BE do not progress towards cancer and thus undergo a regular invasive procedure, which may impact on their psychological and physical well-being while incurring significant cost to the health service. New work that explores cheaper endoscopic or non-invasive ways to identify the at-risk individual provides exciting avenues for research. In future, the diagnosis and monitoring of patients with BE could move away from hospitals and into primary care.

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
OBJECTIVES To find evidence, either corroborating or refuting, for many persisting beliefs regarding the feasibility of carrying out surgical randomised controlled trials with a placebo arm, with emphasis on the challenges related to recruitment, funding, anaesthesia or blinding. DESIGN Systematic review. DATA SOURCES AND STUDY SELECTION The analysis involved studies published between 1959 and 2014 that were identified during an earlier systematic review of benefits and harms of placebo-controlled surgical trials published in 2014. RESULTS 63 trials were included in the review. The main problem reported in many trials was a very slow recruitment rate, mainly due to the difficulty in finding eligible patients. Existing placebo trials were funded equally often from commercial and non-commercial sources. General anaesthesia or sedation was used in 41% of studies. Among the reviewed trials, 81% were double-blinded, and 19% were single-blinded. Across the reviewed trials, 96% (range 50-100%) of randomised patients completed the study. The withdrawal rate during the study was similar in the surgical and in the placebo groups. CONCLUSIONS This review demonstrated that placebo-controlled surgical trials are feasible, at least for procedures with a lower level of invasiveness, but also that recruitment is difficult. Many of the presumed challenges to undertaking such trials, for example, funding, anaesthesia or blinding of patients and assessors, were not reported as obstacles to completion in any of the reviewed trials.

Abstract
"Globus sensation" is often described as the sensation of a lump in the throat associated
with dry swallowing or the need for dry swallowing, which disappears completely during
eating or drinking and for which no organic cause can be established. Due to the uncertain
etiology of "globus sensation", it remains difficult to establish standard treatment
strategies for affected patients. Lately most attention has been focused on
gastroesophageal reflux disease and several reports have indicated that there is a close
relationship between esophageal acid reflux and globus sensation. Nowadays, empirical
therapy with a high dose of a proton pump inhibitor (PPI) is considered to be indicated
for patients with globus sensation, after excluding organic diseases such as pharyngeal
cancer, Zenker's diverticulum, or thyroid enlargement. If patients are nonresponsive to
PPI therapy, evaluation of esophageal motility should be done. In our recent study, 47.9%
had abnormal esophageal motility, with the most common esophageal motility abnormality
being an ineffective esophageal motility in PPI-resistant patients with globus sensation.
This suggests that prokinetics alone or adding prokinetics to PPI should be the treatment
to be considered, although few studies have investigated the efficacy of prokinetics in
the treatment of patients with globus sensation. If patients without any esophageal
motility dysfunctions are nonresponsive to PPI therapy, either cognitive-behavioral
therapy, anti-depressants, or gabapentin could be helpful, although further well-designed,
randomized controlled large-scale studies will be necessary to determine the effectiveness
of each treatment strategy on patients with globus sensation.

Abstract
OBJECTIVES To assess the quantity and quality of randomised, sham-controlled studies of surgery and invasive procedures and estimate the treatment-specific and non-specific effects of those procedures. DESIGN Systematic review and meta-analysis. DATA SOURCES We searched PubMed, EMBASE, CINAHL, CENTRAL (Cochrane Library), PILOTS, PsycInfo, DoD Biomedical Research, clinicaltrials.gov, NLM catalog and NIH Grantee Publications Database from their inception through January 2015. STUDY SELECTION We included randomised controlled trials of surgery and invasive procedures that penetrated the skin or an orifice and had a parallel sham procedure for comparison. DATA EXTRACTION AND ANALYSIS Three authors independently extracted data and assessed risk of bias. Studies reporting continuous outcomes were pooled and the standardised mean difference (SMD) with 95% CIs was calculated using a random effects model for difference between true and sham groups. RESULTS 55 studies (3574 patients) were identified meeting inclusion criteria; 39 provided sufficient data for inclusion in the main analysis (2902 patients). The overall SMD of the continuous primary outcome between treatment/sham-control groups was 0.34 (95% CI 0.20 to 0.49; p<0.00001; I(2)=67%). The SMD for surgery versus sham surgery was non-significant for pain-related conditions (n=15, SMD=0.13, p=0.08), marginally significant for studies on weight loss (n=10, SMD=0.52, p=0.05) and significant for gastroesophageal reflux disorder (GERD) studies (n=5, SMD=0.65, p<0.001) and for other conditions (n=8, SMD=0.44, p=0.004). Mean improvement in sham groups relative to active treatment was larger in pain-related conditions (78%) and obesity (71%) than in GERD (57%) and other conditions (57%), and was smaller in classical-surgery trials (21%) than in endoscopic trials (73%) and those using percutaneous procedures (64%). CONCLUSIONS The non-specific effects of surgery and other invasive procedures are generally large. Particularly in the field of pain-related conditions, more evidence from randomised placebo-controlled trials is needed to avoid continuation of ineffective treatments.

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
The presence of columnar epithelium in the esophagus is associated with two conditions: Barrett's esophagus and heterotopic gastric mucosa. The former results from the metaplastic replacement of the normal distal squamous esophageal lining, is associated with gastroesophageal reflux and is a pre-neoplastic condition. The second is thought as a congenital condition, resulting from the incomplete squamous epithelialization of the esophagus during embryologic development. It is found mainly in the cervical esophagus. Histologically, Barrett's esophagus is composed of an admixture of cardiac mucosa, oxintocardiac mucosa and intestinal metaplasia. Most of heterotopic gastric mucosa consists of oxynticmucosa where the mucosal glands are straight and composed of parietal and chief cells.There are few reports of heterotopic gastric mucosa in the lower esophagus, generally presenting as small islands. In the present report, a series of four cases of large lower esophageal heterotopic gastric mucosa is described. All patients were initially misdiagnosed with Barrett's esophagus and referred for surveillance. The correct diagnosis was based in endoscopic and histological features. In all, a circular tiny strip of squamous mucosa was observed at endoscopy between the lower end of the columnarlined esophagus and the esophagogastric junction, defined as the proximal end of the gastric folds. Biopsy samples taken from the columnar-lined segments of the four patients showed pure oxyntic mucosa.When columnar-lined esophagus is observed in the distal esophagus not in continuity with gastric mucosa, the diagnosis of heterotopic gastric mucosa must be thought and confirmed histologically by the presence of pure oxyntic mucosa.

Abstract
The prevalence of heterotopic gastric mucosa of the upper esophagus (inlet patch) has a wide range depending on the method and detail of examination. The inlet patch is believed to be a congenital malformation that rarely leads to symptoms. We aimed to quantify the prevalence of the inlet patch in a non-referred population and determine if there are any risk factors or associated symptoms. Men between ages 50 and 79 presenting for routine colonoscopy at two clinical sites were recruited to undergo an upper endoscopy. Endoscopists were prompted to examine for the presence of the inlet patch. Of the 822 enrolled patients, 795 had data regarding the presence of an inlet patch. Of these, 55 (6.9%) had an inlet patch identified. Education was inversely associated (odds ratio [OR] advanced degree vs. high school or less = 0.310; 95% confidence interval [CI] = 0.111, 0.869), and tobacco use was positively associated with the presence of an inlet patch (current vs. never smokers OR = 2.87; 95% CI = 1.23, 6.69; former vs. never smokers OR = 1.93; 95% CI = 0.922, 4.02). No association between the inlet patch and symptoms of heartburn, globus, or dysphagia was found. In a cross-sectional study of colon cancer screenees, inlet patches were common and were not associated with symptoms. Tobacco use appears to be associated with the presence of an inlet patch.

Abstract
AIM: To determine the prevalence, demographic, clinical and histopathologic features of heterotopic gastric mucosa (HGM) in Chinese patients.
METHODS: Patients referred to three endoscopy units were enrolled in this study. The macroscopic characteristics of HGM were documented. Biopsies were obtained and observed using hematoxylin and eosin staining. Helicobacter pylori colonization was examined by Whartin-Starry staining.
RESULTS: HGM was observed in 420 Chinese patients, yielding a prevalence of 0.4%. The majority of patients had a single patch (300/420; 71.4%), while the remainder had two (84/420; 20%) or multiple patches (36/420; 8.6%). The size of the patches and the distance from the patch to the frontal incisor teeth varied significantly. The large majority of HGM patches were flat (393/420; 93.6%), whereas the remaining patches were slightly elevated. The primary histological characteristic was fundic-type (216/420; 51.4%) within the HGM patch, and antral- (43/420; 10.2%) and transitional-type (65/420; 15.5%) mucosa were also observed. The prevalence of intestinal metaplasia was 3.1% (13/420) and the prevalence of dysplasia was 1.4% (6/420), indicating the necessity for endoscopic follow-up in patients with HGM. Esophageal and extraesophageal complaints were also observed in patients with HGM. Dysphagia and epigastric discomfort (odds ratios: 6.836 and 115.826, respectively; Ps < 0.05) were independent risk factors for HGM.
CONCLUSION: Clinical complaints should be considered to improve the detection rate of HMG. The prevalence of intestinal metaplasia and dysplasia also indicates a need for endoscopic follow-up.

Abstract
BACKGROUND Heterotopic gastric mucosa is found in the proximal oesophagus, just below the upper oesophageal sphincter, and is encountered when the oesophagus is examined carefully during endoscopy. AIMS In this study on paediatric patients, we aimed to determine the endoscopic prevalence of heterotopic gastric mucosa of the proximal oesophagus (HGMPO), to identify its macroscopic and histological characteristics and to evaluate its clinical features. PATIENTS AND METHODS A total of 1399 patients were examined. Ages, sex, clinical and endoscopic findings of all patients were recorded. Patients with HGMPO were classified in accordance with a clinicopathological classification and information on the treatment and evolution was also recorded. RESULTS Of the 1399 patients, 20 (11 male) were found to have HGMPO. The prevalence of HGMPO was determined to be 1.4%. In five patients, the upper oesophageal and laryngopharyngeal symptoms were remarkable. The clinicopathological classification showed that 15 patients were HGMPO type 1 (asymptomatic) and five were type 2 (symptomatic without morphologic changes). There was no significant association of any other endoscopic finding with the presence of an HGMPO. Proton pump inhibitors treatment was initiated in 16 patients, including those with HGMPO type 2. In one type 2 patient who showed no improvement during medical treatment, endoscopic treatment was indicated (argon plasma ablation). In patients with symptoms attributable to the presence of the inlet patch, the proposed treatment resolved clinical symptoms. CONCLUSION The presence of HGMPO is not an infrequent finding in thorough endoscopies. Although HGMPO does not usually have a symptomatic progression, it can sometimes lead to supraoesophageal symptoms; thus, treatment should be considered.

Abstract
AIM To determine the long-term effect of argon plasma coagulation (APC) of gastric inlet patches in the cervical esophagus for patients suffering from globus sensation. METHODS We intended to follow up all patients between 2004 and 2011 (n = 49) who received argon plasma ablation of gastric inlet patches for globus sensation at our clinic. Symptoms were assessed by a visual analogue scale (VAS) in 31 of 49 patients. Follow-up endoscopy of the upper gastrointestinal tract was performed to confirm residual or relapsed cervical inlet patches. RESULTS After a median period of 27 months, APC was assessed as a successful therapy in 23 of 31 patients (74%). VAS scores decreased significantly from 7.6 to 4.0 in the long term. Twenty-two of 31 patients were willing to undergo follow-up endoscopy. Endoscopy revealed recurrent/residual gastric inlet patches after APC in 11 of 22 cases. These patients suffered from a significant relapse of symptoms in the postinterventional period (p < 0.001). CONCLUSION This retrospective study indicates that APC of gastric inlet patches for the treatment of globus sensation might be a sufficient therapy option. Recurrences or residual heterotopic gastric mucosa are possible and seem to be associated with a relapse of symptoms. Therefore, endoscopic follow-up and retreatment might be necessary if globus sensation is not sufficiently eliminated.

Abstract
BACKGROUND Proximal esophageal heterotopic gastric mucosa or so-called inlet patch in the cervical oesophagus is easily missed on endoscopic examination because of its localisation, usually just below the upper oesophageal sphincter. We evaluated the clinical use of narrow band imaging for detection of inlet patches. METHODS In this prospective, controlled observational study, 1407 subsequent patients underwent oesophagogastroduodenoscopy with or without narrow band imaging on withdrawal of the endoscope in the cervical oesophagus. RESULTS One endoscopist who was not aware of the prospective observation documented 6 (1.17%) cases of inlet patches in 515 oesophagogastroduodenoscopies compared to 4 cases out of 382 (1.05%) performed by the endoscopist who paid special attention to the presence of inlet patches but did not routinely apply narrow band imaging (OR 0.89, CI 95% 0.25-3.20, p=0.85). In comparison, 17 cases of inlet patches out of 510 (3.33%) were detected by the endoscopist who routinely applied narrow band imaging. The detection rate of proximal oesophageal heterotopic gastric mucosa using narrow band imaging was significantly higher compared to white light endoscopy only (OR 3.06, CI 95% 1.39-6.73, p=0.005). CONCLUSIONS Withdrawal of the endoscope from the cervical oesophagus using narrow band imaging increased the detection of inlet patches about three-fold compared to standard white light endoscopy.

Abstract
OBJECTIVE To investigate whether placebo controls should be used in the evaluation of surgical interventions. DESIGN Systematic review. DATA SOURCES We searched Medline, Embase, and the Cochrane Controlled Trials Register from their inception to November 2013. STUDY SELECTION Randomised clinical trials comparing any surgical intervention with placebo. Surgery was defined as any procedure that both changes the anatomy and requires a skin incision or use of endoscopic techniques. DATA EXTRACTION Three reviewers (KW, BJFD, IR) independently identified the relevant trials and extracted data on study details, outcomes, and harms from included studies. RESULTS In 39 out of 53 (74%) trials there was improvement in the placebo arm and in 27 (51%) trials the effect of placebo did not differ from that of surgery. In 26 (49%) trials, surgery was superior to placebo but the magnitude of the effect of the surgical intervention over that of the placebo was generally small. Serious adverse events were reported in the placebo arm in 18 trials (34%) and in the surgical arm in 22 trials (41.5%); in four trials authors did not specify in which arm the events occurred. However, in many studies adverse events were unrelated to the intervention or associated with the severity of the condition. The existing placebo controlled trials investigated only less invasive procedures that did not involve laparotomy, thoracotomy, craniotomy, or extensive tissue dissection. CONCLUSIONS Placebo controlled trial is a powerful, feasible way of showing the efficacy of surgical procedures. The risks of adverse effects associated with the placebo are small. In half of the studies, the results provide evidence against continued use of the investigated surgical procedures. Without well designed placebo controlled trials of surgery, ineffective treatment may continue unchallenged.

Abstract
Globus is a topic of interest for many specialties including otorhinolaryngology, gastroenterology and psychiatry/psychosomatic medicine, but, although many hypotheses have been suggested, key questions about its aetiology remain. This Review provides an overview of the extensive literature concerning this topic and discusses the quality of the evidence to date. Globus has been associated with oropharyngeal structural lesions, upper oesophageal sphincter disorders, oesophageal disorders, GERD, psychosocial factors and psychiatric comorbidity. However, findings are often contradictory and the literature remains highly inconclusive. Indeed, with the exception of patients with structural-based globus, the Rome III criteria for functional globus only apply to a subgroup of patients with idiopathic globus. In clinical reality, there exists a group of patients who present with idiopathic (nonstructural) globus, but nevertheless have dysphagia, odynophagia or GERD-exclusion criteria for globus diagnosis according to Rome III. The symptomatology of patients with globus might be broader than previously thought. It is therefore crucial to approach globus not from one single perspective, but from a multifactorial point of view, with focus on the coexistence and/or interactions of different mechanisms in globus pathogenesis. This approach could be translated to clinical practice by adopting a multidisciplinary method to patients presenting with globus.

Abstract
BACKGROUND Heterotopic gastric mucosa (HGM) may be located at sites throughout the gastrointestinal (GI) tract. Clinical characteristics of HGM, role of Helicobacter pylori infection, natural history, and relationship to neoplastic transformation have not sufficiently been explored. AIM To retrospectively study the prevalence, histological features, and clinical characteristics of HGM among Chinese patients who underwent upper GI endoscopy. METHODS Endoscopic, histological, and clinical records of patients, who underwent upper GI endoscopy (n = 6802) and colonoscopy (n = 3504), respectively, between May 2011 and May 2012, were collected and retrospectively analyzed. A total of 6716 sex- and age-matched patients without HGM were enrolled as controls. RESULTS HGM was diagnosed in 86 cases (51 esophageal, 0.75%; 35 duodenal, 0.51%). Male:female ratio was 1.4:1 (30/21) for esophageal HGM, 1.7:1 (22/13) for duodenal HGM, and 1.1:1 (3557/3159) for controls. Two histopathological types of HGM were identified: foveolar epithelium alone and foveoloar epithelium together with gastric glands. Helicobacter pylori were present in 19.6% of cases with esophageal HGM and 20.0% of cases with duodenal HGM. Esophageal HGM was significantly associated with dysphagia and globus; duodenal HGM was not significantly associated with GI symptoms. Intestinal metaplasia was present in two and three patients in both groups, respectively, with no dysplasia or carcinoma. CONCLUSION HGM was present in fewer patients undergoing upper GI endoscopy, and it was more often present in men. A careful endoscopic examination is required to diagnose HGM, and it should be supported with a biopsy when indicated.

Abstract
AIM: To compare the diagnostic yield of heterotopic gastric mucosa (HGM) in the cervical esophagus with conventional imaging (CI) and narrow-band imaging (NBI).
METHODS: A prospective study with a total of 760 patients receiving a CI examination (mean age 51.6 years; 47.8% male) and 760 patients undergoing NBI examination (mean age 51.2 years; 45.9% male). The size of HGM was classified as small (1-5 mm), medium (6-10 mm), or large (> 1 cm). A standardized questionnaire was used to obtain demographic characteristics, social habits, and symptoms likely to be related to cervical esophageal HGM, including throat symptoms (globus sensation, hoarseness, sore throat, and cough) and upper esophageal symptoms (dysphagia and odynophagia) at least 3 mo in duration. The clinicopathological classification of cervical esophageal HGM was performed using the proposal by von Rahden et al.
RESULTS: Cervical esophageal HGM was found in 36 of 760 (4.7%) and 63 of 760 (8.3%) patients in the CI and NBI groups, respectively (P = 0.007). The NBI mode discovered significantly more small-sized HGM than CI (55% vs 17%; P < 0.0001). For the 99 patients with cervical esophageal HGM, biopsies were performed in 56 patients; 37 (66%) had fundic-type gastric mucosa, and 19 had antral-type mucosa. For the clinicopathological classification, 77 patients (78%) were classified as HGM I (asymptomatic carriers); 21 as HGM II (symptomatic without morphologic changes); and one as HGM III (symptomatic with morphologic change). No intraepithelial neoplasia or adenocarcinoma was found.
CONCLUSION: NBI endoscopy detects more cervical esophageal HGM than CI does. Fundic-type gastric mucosa constitutes the most common histology. One-fifth of patients have throat or dysphagic symptoms.

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.

Abstract
Although the pathogenesis of cervical inlet patch (CIP) is not fully understood, most authors consider it as a congenital abnormality, whereas others surmise it to be related to gastroesophageal reflux disease (GERD). We aimed to evaluate esophageal function and the prevalence of GERD and Barrett's esophagus in patients with CIP. GERD is defined by the presence of erosive esophagitis or an abnormal pH monitoring. Seventy-one consecutive patients with endoscopic and histological evidence of CIP were prospectively evaluated. Esophageal symptom analysis, 24-hour simultaneous biliary reflux and double-channel pH-monitoring, and esophageal manometry were carried out in 65/71 (92%) patients and in 25 matched controls. Six patients were not suitable for testing and were, therefore, excluded. The histological evaluation of the heterotopic islands showed cardia and/or oxyntic mucosa in 64/65 (98%) patients and specialized intestinal metaplasia (SIM) in one patient (2%). The cardia and/or oxyntic mucosa was accompanied by focally appearing pancreatic acinar metaplasia and pancreatic ductal metaplasia in 7/64 (11%) and in 1/64 (2%), superficial mucous glands in 6/64 (9%), and SIM in 2/64 (3%) cases. In total, SIM was present in three patients (5%), and one of them had low-grade dysplasia. At the gastroesophageal junction, 28 (43%) patients had columnar metaplasia, including nine (14%) patients with SIM. Erosive esophagitis was present in 37 (57%) cases. Thirty-two patients (49%) had abnormal acid reflux in the distal and 25 (38%) in the proximal esophagus. Abnormal biliary reflux was present in 25 (38%) cases. On the basis of endoscopic and pH studies, GERD was established in 44/65 (68%) patients. Typical reflux symptoms were common (33/65, 51%). The combined 24-hour biliary and double-channel pH-monitoring detected significantly more significant acidic reflux at both measurement points and significantly longer bile exposure time in the distal esophagus in patients with CIP. Acid secretion in the CIP was detected in three (5%) cases. Esophageal manometry revealed decreased LES pressure and prolonged relaxation with decreased peristaltic wave amplitude, and an increased number of simultaneous contractions in the esophageal body. The detailed evaluation of the esophageal morphology and function in subjects with CIP showed a high prevalence of GERD and Barrett's esophagus. Further studies are needed to evaluate whether combined acidic and biliary reflux is able to promote similar histomorphological changes in the CIP, as it is shown distally in patients with Barrett's esophagus.
