Abstract
OBJECTIVES There is currently no reference standard test for the detection of the extra-esophageal manifestations of gastroesophageal reflux disease (GERD). The current suite of diagnostic tests principally assesses reflux events in the esophagus. A new scintigraphic technique has been developed and validated against reference standards. It allows direct visualization of refluxate in the laryngopharynx and lungs. METHODS Fifty patients were assessed by scintigraphy before and after fundoplication at a single nuclear medicine facility. Standardized reflux symptom indices (RSIs) were obtained from each patient before and after surgery. Patients were scanned after oral 99 m technetium Fyton administration with early dynamic images and delayed SPECT/CT images of the head, neck, and lungs. ANOVA, Spearman correlation, and the Student's t-test were utilized for analysis. RESULTS The study population (35F, 15 M) had a mean age of 63.9 years. Mean BMI was 26.8 with 67% being overweight or obese. All patients had significant reflux. SPECT/CT showed LPR events in 45/50 and pulmonary micro-aspiration (PMA) in 45/50 preoperatively and in 36/50 and 20/50 postoperatively, respectively. The RSI, cough, and throat clearing indices showed a significant fall postoperatively (p < 0.001). Frequency of scintigraphic reflux events was reduced from a mean of 4.5 in 30 min to 2.9 (t = 9.1, p = 0.004). CONCLUSION The novel scintigraphic test detects esophageal and extra-esophageal reflux events and permits direct visualization of refluxate in the head and neck structures and lungs. It correlates well with symptoms of reflux in the esophagus and extra-esophageal structures and the response to therapy. LEVEL OF EVIDENCE Although prospective, the study did not randomize patients and in effect each patient became their own control following an intervention (fundoplication). Thus, the study is Level 3 evidence Laryngoscope, 2024.

Abstract
AIM A recent study has reported that anti-reflux surgery reduced the risk of lung cancer. However, the exact causal association between gastro-esophageal reflux disease (GORD) and lung cancer remains obscure. Therefore, we conducted a multivariable and network Mendelian randomization (MR) study to explore this potential association and mediation effect. METHODS Independent single nucleotide polymorphisms (SNPs) strongly associated with GORD were selected as instrumental variables (IVs) from the corresponding genome-wide association studies (GWAS). The summary statistics were obtained from the largest GORD GWAS meta-analysis of 367 441 (78 707 cases) European individuals, and the summary statistics of lung cancer and pathological subtypes came from International Lung Cancer Consortium (ILCCO) and FinnGen databases. Univariable and multivariable MR analyses were performed to investigate and verify the causal relationship between genetically predicted GORD and lung cancer. Network MR analysis was conducted to reveal the mediating role of GORD between smoking initiation and lung cancer. RESULTS The univariable MR analysis demonstrated that GORD was associated with an increased risk of total lung cancer in both ILCCO [inverse variance weighted (IVW): odds ratio (OR) = 1.37, 95% confidence interval (CI) 1.16-1.62, P = 1.70E-04] and FinnGen database (IVW: OR = 1.25, 95% confidence interval CI 1.03-1.52, P = 2.27E-02). The consistent results were observed after adjusting the potential confounders [smoking traits, body mass index (BMI) and type 2 diabetes] in multivariable MR analyses. In subtype analyses, GORD was associated with lung adenocarcinoma (IVW: OR = 1.27, 95% CI 1.02-1.59, P = 3.48E-02) and lung squamous cell carcinomas (IVW: OR = 1.50, 95% CI 1.22-1.86, P = 1.52E-04). Moreover, GORD mediated 32.43% (95% CI 14.18-49.82%) and 25.00% (95% CI 3.13-50.00%) of the smoking initiation effects on lung cancer risk in the ILCCO and FinnGen databases, respectively. CONCLUSION This study provides credible evidence that genetically predicted GORD was significantly associated with an increased risk of total lung cancer, lung adenocarcinoma and lung squamous cell carcinomas. Furthermore, our results suggest GORD is involved in the mechanism of smoking initiation-induced lung cancer.

Abstract
INTRODUCTION Paraoesophageal hernias (PEH) are often symptomatic and can lead to life-threatening complications such as volvulus and ischaemia. Dyspnoea is one of the most prevalent symptoms of giant hiatus herniae. The primary outcome of this study is resolution of dyspnoea following composite repair of giant paraoesophageal hernia. Secondary outcomes include complications of surgery, hernia recurrence rates and effect of recurrence on dyspnoea. METHODS Data were extracted from a prospectively maintained single-surgeon database containing records of all patients undergoing composite repair of paraoesophageal hernia. Patients presenting with dyspnoea who underwent composite laparoscopic repair of giant (>30% of stomach above diaphragm) paraoesophageal hernia between March 2009 and December 2015 were included. RESULTS Inclusion criteria were met by 154 patients. The mean age at time of surgery was 71.2 years (range 49-93, SD 9.66) with an average BMI of 28 (range 19-38kg/m2, SD 4.1). On average hernia contained 64% of stomach (range 30-100%, SD 20.2). One procedure was converted to laparotomy. Surgery resulted in near complete resolution of dyspnoea (2.6% postoperatively, p<0.001). Recurrence rate was 24% and was not associated with persistent dyspnoea. There was one death and two significant complications. CONCLUSION Dyspnoea resolves following laparoscopic repair of giant paraoesophageal hernia. The presence of dyspnoea in patients with known large paraoesophageal hernia should be regarded as an indication for referral to a surgical service with expertise in hiatal hernia management.

Abstract
Background Pertussis is an infectious disease of the respiratory tract with a changing epidemiology. An increasing incidence has been found in the adult population with recurrent infections possibly related to changes in the current vaccine. Is there an association between pertussis infection, refractory cough and atypical gastro-oesophageal reflux (GORD)? Does this magnify and compound respiratory complications? Methods Observational study which compares post-pertussis (n=103) with non-pertussis patients (n=105) with established GORD. Patients were assessed for laryngopharyngeal reflux and aspiration of refluxate by a novel scintigraphic study. Results Both groups showed severe GORD in association with high rates of laryngopharyngeal reflux (LPR) and pulmonary aspiration and lung disease. High rates of hiatus hernia and clinical diagnosis of “atypical” asthma showed correlations with pulmonary aspiration. Conclusions A high level of new onset LPR and lung aspiration has been shown in patients with chronic cough after recent pertussis infection by a novel scintigraphic technique with fused hybrid x-ray computed tomography (SPECT/CT).

Abstract
INTRODUCTION Chronic disease poses a major problem for the Australian healthcare system as the leading cost-burden and cause of death. Gastroesophageal reflux disease (GORD) typifies the problems with a growing prevalence and cost. We hypothesise that a scintigraphic test could optimise the diagnosis, especially in problematic extraoesophageal disease. MATERIALS AND METHODS Data was collected from 2 groups of patients. Patients undergoing fundoplication for severe GORD (n = 30) and those with atypical symptoms (n = 30) were studied by scintigraphy and 24-hour oesophageal pH, impedance and manometry. RESULTS Mean age of cohort was 55.8 years with 40 females and 20 males. Body mass index was a mean of 28.3. DeMeester score was normal in 12/60 with atypical symptoms and abnormal in the rest. Good correlation was shown between scintigraphy and impedance, manometry and distal pH readings. Pulmonary aspiration was shown in 25/60 (15 with atypical symptoms) and LPR in 20/30. Several impedance, manometric and scintigraphic finding were good predictors of lung aspiration of refluxate. CONCLUSION Scintigraphy provides a good tool for screening patients with typical and atypical symptoms of GORD. It is well correlated with the standard methods for the diagnosis and provides visual evidence of LPR and lung aspiration.

Abstract
The aim of this study was to characterise pulmonary aspiration of refluxate in patients with gastroesophageal reflux disease (GORD) and laryngopharyngeal reflux (LPR) by continuous pulse oximetry (SpO2) during the supine phase of a scintigraphic reflux study. Variables assessed for significance included age, hiatus hernia, frequency, amplitude of reflux and clearance of reflux from the oesophagus/pharynx. The patients included in this study had established GORD and LPR by clinical history. All patients underwent fused three- dimensional scintigraphic/ X-ray computed tomography (CT) and simultaneous continuous pulse oximetry when supine for 30 minutes. A total of 265 patients (40.4% M, 59.6% F) were studied. Mean age of aspirators was 57.0 years and non-aspirators was 53.5 years. Seven patients had baseline oxygen saturation <95%, with 6/7 showing aspiration by scintigraphy. The remainder had mean baseline saturation of 97.7%. Continuous SpO2 monitoring showed a significant fall in pulmonary aspirators after 20 min of supine acquisition with significant variability. Analysis revealed a cyclic event every 1.5 min in aspirators only. Panel regression analysis showed a significant effect of age, hiatus hernia, pulse rate and reflux frequency on the fall in SpO2. Pulmonary aspiration in patients with LPR and GORD is characterised by acute oxygen desaturation. Variables affecting oxygen desaturation were age, hiatus hernia, pulse rate and reflux frequency. A cyclic event was observed every 1.5 min in aspirators and may be due to reflex homeostatic mechanism attempting to correct perceived hypoxia.

Abstract
Gastroesophageal reflux disease (GERD) is defined by retrograde reflux of gastric contents to the esophagus leading to various signs and symptoms that range from heartburn/regurgitation to the development of extraesophageal respiratory syndromes like asthma. Although a cause-effect relationship has been proposed, evidence suggests that these two entities share a complex mechanism that may be reciprocal to each other. The understanding of the underlying mechanisms is imperial due to the fact that asthmatic patients may benefit from reflux therapy with subsequent improvement in pulmonary function testing and quality of life. This study has revised available literature in order to provide evidence for a nexus between GERD and asthma based on clinical correlation, pathophysiology, and pharmacologic management.

Abstract
OBJECTIVE Reflux scintigraphy is often used to diagnose gastro-esophageal reflux disease (GERD). However, the efficacy of this study remains controversial. Our aim was to determine the role of reflux scintigraphy in diagnosing GERD by comparing it to 24 h combined pH-impedance study as the gold standard. MATERIALS AND METHODS Adult patients who presented for investigations of reflux symptoms were prospectively recruited into the study. All patients underwent high resolution esophageal manometry and those with major motor disorders of the esophagus were excluded. Eligible patients immediately underwent reflux scintigraphy following insertion of the pH-impedance catheter. RESULTS Thirty patients were included in the study. Using a total acid exposure time (AET) of >4.2% as the reference for abnormal acid reflux, reflux scintigraphy had a sensitivity and specificity of 62.5 and 68.2%, respectively, in detecting acid reflux. When compared to AET >6%, reflux scintigraphy had a sensitivity and specificity of 66.7 and 62.5%, respectively, and a positive predictive value of 30.8% and a negative predictive value of 88.2%. There were no associations between outcomes of reflux scintigraphy and total AET (p = .46), total (acid or non-acid) reflux events (p = 0.11), proximal AET (p = .33) or the number of proximal reflux episodes (p = .75) on 24 h pH-impedance study. CONCLUSIONS Reflux scintigraphy has limited role in diagnosing GERD when compared to 24 h combined pH-impedance monitoring.

Abstract
BACKGROUND The management of patients with gastroparesis and recurrent reflux after previous fundoplication is challenging. The aim of this study was to evaluate the safety and efficacy of subtotal gastrectomy with Roux-en-Y reconstruction as a remedial procedure in this select patient population. METHOD Retrospective analysis of a prospectively populated database identified all patients that underwent subtotal gastrectomy with Roux-en-Y reconstruction (SGRNY) due to reflux symptoms and delayed gastric emptying (DGE). Demographic, intra-operative and post-operative data including pre and post-operative modified reflux aspiration scintigraphy studies were evaluated. Standardized questionnaires were used to assess symptomatic outcomes. RESULTS From 2018 SGRNY has been selectively performed in 13 patients. Preoperative workup confirmed DGE and severe symptomatic reflux in all patients. The median number of previous fundoplication and or hiatal hernia operations was two (range 1-3). The mean hospital length of stay was 10 ± 6 days. Post-operative morbidity was experienced in three patients (23%). Seven patients (64%) had significant improvement or complete resolution of reflux on post-operative scintigraphy. Symptom improvement was reported in 92% of patients. CONCLUSION In a select patient cohort with post-fundoplication reflux and DGE symptoms, SGRNY is a moderately safe and effective salvage option.

Abstract
Background Pulmonary manifestation of gastro-oesophageal reflux disease (GORD) is a well-recognised entity; however, little primary reported data exists on presenting symptoms of patients in whom reflux micro-aspiration is confirmed. The aim of this study is to report symptoms and presenting patterns of a large group of patients with confirmed reflux micro-aspiration. Patients and methods Data was extracted from a prospectively populated database of patients referred to a tertiary specialist centre with severe, refractory or atypical reflux. Patients with reflux micro-aspiration on scintigraphy were included in this study. A separate group included patients with evidence of proximal reflux to the level of pharynx when supine and/or upright. Results Inclusion criteria were met by 243 patients with confirmed reflux micro-aspiration (33% males; mean age 59). Most common symptoms amongst patients with micro-aspiration were regurgitation (72%), cough (67%), heartburn (66%), throat clearing (65%) and dysphonia (53%). The most common two-symptom combinations were heartburn/regurgitation, cough/throat clearing, regurgitation/throat clearing, cough/regurgitation and dysphonia/throat clearing. The most common three-symptom combinations were cough/heartburn/regurgitation, cough/regurgitation/throat clearing and dysphonia/regurgitation/throat clearing. Cluster analysis demonstrated two main symptom groupings, one suggestive of proximal volume reflux symptoms and the other with motility/inflammatory bowel syndrome-like symptoms (bloat, constipation). Conclusion The combination of typical symptoms of GORD such as heartburn or regurgitation and a respiratory or upper aero-digestive complaint such as cough, throat clearing or voice change should prompt consideration of reflux micro-aspiration. Patients with reflux micro-aspiration most commonly present with a combination of regurgitation and/or heartburn and cough and/or throat clearinghttps://bit.ly/3GM8cNS

Abstract
INTRODUCTION Previously described methodologies for detecting laryngopharyngeal reflux (LPR) have limitations. Symptoms alone are non-diagnostic, and pH-impedance studies have poor sensitivity. Pulmonary micro-aspiration is under-recognised in LPR and gastro-esophageal reflux disease (GERD). The present study aimed to describe the results of a modified technique for scintigraphic reflux studies in two groups with severe reflux: those with typical reflux symptoms and those with laryngopharyngeal manifestations of reflux. METHODS A prospective database of severely symptomatic, treatment-resistant reflux patients was grouped based upon predominant symptom profile of typical GERD or LPR. All patients underwent reflux scintigraphy. Results were obtained for early scintigraphic reflux contamination of the pharynx and proximal esophagus, and delayed contamination of the pharynx and lungs after 2 h. RESULTS 187 patients were studied (82 GERD, 105 LPR). The LPR patients were predominantly female (70.5% vs. 56.1%; p = 0.042) and older than the GERD group (median age 60 years vs. 55.5 years; p = 0.002). Early scintigraphic reflux was seen at the pharynx in 89.2% (GERD 87.7%, LPR 90.4%; p = 0.133), and at the proximal esophagus in 89.7% (GERD 88.9%, LPR 90.4%; p = 0.147). Delayed contamination of the pharynx was seen in 95.2% (GERD 93.9%, LPR 96.2%; p = 0.468). Delayed pulmonary aspiration was seen in 46% (GERD 36.6%, LPR 53.3%; p = 0.023). CONCLUSION Reflux scintigraphy demonstrated a high rate of reflux-related pulmonary aspiration. Contamination of the proximal esophagus and pharynx was observed frequently in both groups of severe disease. The likelihood of pulmonary aspiration and potential pulmonary disease needs to be entertained in severe GERD and LPR.

Abstract
INTRODUCTION Severe oesophageal dysmotility is associated with treatment-resistant reflux and pulmonary reflux aspiration. Delayed solid gastric emptying has been associated with oesophageal dysmotility; however, the role of delayed liquid gastric emptying (LGE) in the pathophysiology of severe reflux disease remains unknown. The purpose of this study is to examine the relationship between delayed LGE, reflux aspiration, and oesophageal dysmotility. METHODS Data were extracted from a prospectively populated database of patients with severe treatment-resistant gastro-oesophageal reflux disease. All patients with validated reflux aspiration scintigraphy and oesophageal manometry were included in the analysis. Patients were classified by predominant clinical subtype as gastro-oesophageal reflux (GOR) or laryngopharyngeal reflux. LGE time of 22 min or longer was considered delayed. RESULTS Inclusion criteria were met by 631 patients. Normal LGE time was found in 450 patients, whilst 181 had evidence of delayed LGE. Mean liquid half-clearance was 22.81 min. Reflux aspiration was evident in 240 patients (38%). Difference in the aspiration rates between delayed LGE (42%) and normal LGE (36%) was not significant (p = 0.16). Severe ineffective oesophageal motility (IOM) was found in 70 patients (35%) and was independent of LGE time. Severe IOM was strongly associated with reflux aspiration (p < 0.001). GOR dominant symptoms were more common in patients with delayed LGE (p = 0.03). CONCLUSION Severe IOM was strongly associated with reflux aspiration. Delayed LGE is not associated with reflux aspiration or severe IOM. Delayed LGE is more prevalent in patients presenting with GOR dominant symptoms.

Abstract
Gastroesophageal reflux disease (GERD) is a common and growing problem in most western countries. It may present with the typical symptoms of heartburn and regurgitation or with the effects of extra-esophageal disease. We have developed and validated a scintigraphic test that evaluates reflux at both sites in patients at high risk of laryngopharyngeal reflux and lung aspiration. We hypothesized that the test may be able to separate physiologic reflux from pathological reflux and examined this possibility in normal asymptomatic volunteers. Asymptomatic volunteers were screened with the Belafsky reflux symptom index (RSI) and entered into the trial if scores were less than 13. 99mTc Phytate was ingested orally and dynamic studies from the pharynx to the stomach were obtained while upright and supine. A delayed study of the thorax was also obtained for lung aspiration of refluxate. Studies were semi-quantitated graphically as time-activity curves. A total of 25 volunteers were studied (13 M, 12 F) with a mean age of 57.5 yr (Range 40-85 yr). None gave a history of heartburn or regurgitation. Mean RSI was 4.1 (range 0-10). Testing showed upright gastroesophageal reflux to the mid-upper esophagus without pharyngeal contamination in 32%. None of the subjects showed supine reflux or lung aspiration. This result corresponds well with intraluminal impedance/pH monitoring in normal volunteers. The scintigraphic reflux test gives similar results to standard intraluminal impedance/pH studies in normal volunteers. A significant proportion of asymptomatic volunteers demonstrate upright reflux only.

Abstract
BACKGROUND The inclusion of scintigraphy in the diagnostic algorithm for gastroesophageal reflux is controversial due to variability in methodology and reporting. A novel scintigraphic reflux study has been developed and validated against the current standards for the diagnosis of gastroesophageal reflux disease (GORD). OBJECTIVE To compare a new scintigraphic reflux test against historic techniques and standardised diagnostic reference tests for gastroesophageal reflux disease. METHODS Paired scintigraphic studies were conducted in seventeen patients. All patients underwent at least one other standardised diagnostic reflux test such as 24- hour oesophageal impedance/ pH, and oesophageal manometry, barium swallow, gastroscopy or the Peptest. Patients inadvertently presented at sites B for scintigraphic reflux testing rather than at Site A which was part of an approved study. The findings from sites B did not correlate with clinical symptoms and other diagnostic reference tests from GORD. These studies were then repeated at Site A with approval from the patients. A second reflux study was performed at site A, utilising a novel technique with the capability of assessing oesophageal and extra-oesophageal disease. RESULTS The Site A technique shows good concordance with the reference diagnostic tests with an accuracy of 82.4% and kappa of 0.64 (SE: 0.16, p = 0.00). Site B had an overall accuracy of 47.1% and kappa of 0.066 (SE: 0.068, p = 0.45). CONCLUSION The Site A technique shows higher accuracy than either site B or the historic reflux techniques. It has characteristics that make it an effective screening tool for assessment of local oesophageal disease and its extraoesophageal manifestations.

Abstract
Gastroesophageal reflux disease (GERD) is defined by the presence of symptoms induced by the reflux of the stomach contents into the esophagus. Although clinical manifestations of GERD typically involve the esophagus, extra-esophageal manifestations are widespread and less known. In this review, we discuss extra-esophageal manifestations of GERD, focusing on clinical presentations, diagnosis, and treatment. Common extra-esophageal manifestations of GERD include chronic cough, asthma, laryngitis, dental erosions, and gingivitis. Extra-esophageal involvement can be present also when classic GERD symptoms are absent, making the diagnosis more challenging. Although available clinical studies are heterogeneous and frequently of low quality, a trial with proton pump inhibitors can be suggested as a first-line diagnostic strategy in case of suspected extra-esophageal manifestations of GERD.

Abstract
BACKGROUND Gastro-esophageal reflux disease (GERD) can present with typical or atypical or laryngo-pharyngeal reflux (LPR) symptoms. Pulmonary aspiration of gastric refluxate is one of the most serious variants of reflux disease as its complications are difficult to diagnose and treat. The aim of this study was to establish predictors of pulmonary aspiration and LPR symptoms. METHODS Records of 361 consecutive patient from a prospectively populated database were analyzed. Patients were categorized by symptom profile as predominantly LPR or GERD (98 GER and 263 LPR). Presenting symptom profile, pH studies, esophageal manometry and scintigraphy and the relationships were analyzed. RESULTS Severe esophageal dysmotility was significantly more common in the LPR group (p = 0.037). Severe esophageal dysmotility was strongly associated with isotope aspiration in all patients (p = 0.001). Pulmonary aspiration on scintigraphy was present in 24% of patients. Significant correlation was established between total proximal acid on 24-h pH monitoring and isotope aspiration in both groups (p < 0.01). Rising pharyngeal curves on scintigraphy were the strongest predictors of isotope aspiration (p < 0.01). CONCLUSIONS Severe esophageal dysmotility correlates with LPR symptoms and reflux aspiration in LPR and GERD. Abnormal proximal acid score on 24-h pH monitoring associated with pulmonary aspiration in reflux patients. Pharyngeal contamination on scintigraphy was the strongest predictor of pulmonary aspiration.
