Gastroesophageal reflux (GER) is a functional entity which is defined as "the involuntary reflux of the gastric contents in the oesophagus, without vomiting and without the involvement of either the gastric, abdominal or diaphragmatic muscles". It is therefore a question of a syndrome which is independent of the anatomical abnormalities in the cardio-tuberositic region (i.e. hiatal hernia). It may also show itself through digestive symptoms, thoracic pains, ENT symptoms and breathing complications. The presence of the latter has been clearly established in certain circumstances: --in infants, GER can cause obstructive apneas, which are responsible for sudden inexplicable deaths (SID): GER and SID have very similar epidemiological characteristics; polygraphic recordings showed that a reflux may immediately precede the onset of obstructive apnea; the instillation of 0.1 N hydrochloric acid in the oesophagus of children with GER causes an apnea. Medical or surgical treatment of the reflux prevents the recurrence of these accidents; --in adults, and older children, GER is responsible for coughs, recurring bronchopneumopathies and asthma; long-term recordings of the oesophageal pH have proved that there is a time-relationship between the two events. Scintigraphic studies have shown the pulmonary contamination by a radioactive isotope placed in the stomach the previous evening. GER has been equally suspected for conditions such as lung abscess, bronchiectasis and hemoptysis, but here it is more difficult to prove. With certain pulmonary fibroses, histological lesions have been compared with those observed during inhalation bronchopneumopathies, but it is difficult to establish a link with a reflux; --functional respiratory studies have not produced a specific functional entity for patients with GER; --careful medical treatment or surgical correction of GER lead to the sedation of respiratory symptoms (RS) in the majority of cases; --the association frequency of a GER and of RS is difficult to establish because of the diversity of the means of diagnosis employed in the past and also because of the heterogeneity of the studied populations, but the frequency is nevertheless high, indeed significantly higher than the prevalence of GER in the general population. The mechanisms which link GER and RS are not well known: first of all, there is the failure of normal antireflux mechanisms and also certain hormonal, alimentary (coffee, alcohol, tobacco, etc.) and therapeutic (theophylline, betamimetics) factors, which facilitate the reflux.(ABSTRACT TRUNCATED AT 400 WORDS)

In otorhinolaryngology, the relationship between gastroesophageal reflux (GER) and pharyngolaryngeal disorders is well-known. In fact, many patients with GER debut with head and neck symptoms or are first seen by an otolaryngologist. We proposed to identify the ENT symptoms most frequently associated with GER, to differentiate between physiological and pathological GER, and to confirm the effectiveness of antacid treatment. Our study included 20 ambulatory patients who presented pharygolaryngeal symptoms and clinical manifestations of GER (heartburn and regurgitation). The patients underwent a complete ENT examination and were referred to a gastroenterologist for esophagoscopy, manometry, and 24-hour pH monitoring. All patients received antireflux therapy for one month (ranitidine 150 mg given twice daily). We conclude that GER produces a variety of manifestations, but the most frequent pharyngolaryngeal symptoms and physical findings were globus pharyngeus and erythema of the arytenoids, respectively. Pathological GER was found in only one third of our patients and 90% responded well to treatment.

Between June 1994 and June 1996, we performed a 24-hour oesophageal pH monitoring in 116 adult patients. A retrospective analysis of the data is hereby presented. The principal indications include a chronic cough, recurrent laryngitis and noncardiac chest pain. In 65.5% of our cases, a pathological gastroesophageal reflux was found during pH monitoring. The symptom-index (SI) concerning the digestive and ENT symptoms did correlate in 1/3 of the cases while it was significant in only 15% of the cases with pulmonary and cardiac symptoms. 24-hour pH monitoring remains the method of choice for the study of gastroesophageal reflux and analysis of the SI is indispensable to evaluate the correlation of symptoms with episodes of reflux.

Gastroesophageal reflux disease (GERD) is the most common esophageal disease. It typically presents with heartburn and regurgitation, but it may also cause atypical symptoms, either alone or in combination. About 20 to 60 percent of patients with GERD have ENT symptoms without any heartburn. The most common ENT symptom is a globus sensation, yet there are many possible clinical signs such as laryngitis, pharyngitis, sinusitis, laryngospasm, laryngeal edema and granuloma that may mislead the initial work-up. In this work the pathophysiology, symptomatology, diagnostic measurements and therapeutic options of GERD are discussed. It is suggested that GERD has to be included into differential diagnostic approaches especially when routine treatment of these ENT diseases failes.

The past decade has witnessed increasing interest in the supraesophageal (ear, nose, and throat (ENT)) symptoms potentially caused by gastroesophageal reflux disease (GERD). Hoarseness, halitosis, problems with vocal presentations, excessive phlegm, frequent throat clearing, globus sensation, sore throat, cough, aspiration, laryngospasm, and laryngeal carcinoma are some, but not all of the ENT symptoms that have been attributed to GERD (1). The availability of highly effective medical and surgical therapies allows for control of these symptoms in many patients adding to the importance of accurately diagnosing GERD.

A variety of pulmonary and ear, nose, and throat (ENT) symptoms and disorders are considered to be extraoesophageal manifestations of gastro-oesophageal reflux disease (GORD). These extraoesophageal manifestations include asthma, chronic cough, laryngeal disorders, and various ENT symptoms. Recent studies have established that GORD underlies or contributes to chronic sinusitis, chronic otitis media, paroxysmal laryngospasm, excessive throat phlegm, and postnasal drip. Traditionally, management of extraoesophageal GORD manifestations relies on prolonged empiric therapy with high doses of proton pump inhibitors (PPI), followed by pH monitoring under PPI in refractory cases. Recent studies found no benefit of empiric long term high dose PPI therapy. The diagnostic yield of endoscopy in extraoesophageal GORD manifestations seems higher than previously appreciated while pH monitoring under PPI therapy has a low yield. Based on these new findings, a new management algorithm can be proposed that uses short term empiric PPI therapy and GORD investigations off PPI. Well designed controlled studies evaluating the proposed management algorithms and treatment approaches in this area are urgently needed.

Gastroesophageal reflux disease (GERD) is present in up to 75% of patients with chronic refractory ear, nose, and throat (ENT) symptoms, and proton pump inhibitor (PPI) therapy induces symptom relief in the majority of these patients. It has been suggested that endoscopic findings and quantification of esophageal acid exposure may help to predict the long-term outcome of medical therapy, but prospective studies that confirm this hypothesis are lacking. The aim of the present study was to investigate the relationship of endoscopic findings and quantification of reflux with long-term outcome in patients with reflux-related ENT symptoms. One hundred six consecutive patients with chronic refractory unexplained ENT symptoms underwent upper GI endoscopy, 24-hr dual-channel esophageal pH and Bilitec (n = 35) monitoring, and esophageal manometry. Subsequently, all were treated with omeprazole, 20 mg b.i.d., and patients were followed at 2-week intervals until symptom relief. Four weeks later, omeprazole therapy was gradually decreased and the lowest effective omeprazole maintenance dose, if any, was determined. Eighty-one patients (49 men; mean age, 50) experienced a clear or excellent therapeutic response after, on average, 4 weeks of omeprazole, 20 mg b.i.d. In 36 patients (44%; group A), PPI treatment could be stopped completely, 27 patients (33%; group B) required a maintenance dose of omeprazole, 20 mg/day, and 18 patients (22%; group C) required maintenance with omeprazole, 40 mg/day. The prevalence of reflux esophagitis was significantly lower in group A patients, who also had significantly lower distal esophageal acid exposure, proximal esophageal acid exposure, and esophageal duodenogastroesophageal reflux exposure compared to groups B and C. Multivariate analysis identified the presence of esophagitis and pathological distal esophageal acid exposure as risk factors for the need of maintenance therapy. In patients with reflux-related ENT symptoms, initial findings on upper GI endoscopy and 24-hr pH-metry help to predict the need for maintenance therapy.

Gastroesophageal reflux disease (GERD) is associated with a variety of extraesophageal symptoms including asthma, chronic cough, laryngeal disorders, and various ENT symptoms. Recent studies suggest that GERD underlies or contributes to chronic sinusitis, chronic otitis media, dental erosion, and obstructive sleep apnea syndrome (OSAS). In this article, we review the prevalence, diagnosis, and treatment of extraesophageal symptoms and including Montreal definition, a new definition and classification of GERD by an International Consensus Group.

In adults, several extra-digestive manifestations (cough, asthma, angina-like chest pain, ENT symptoms, dental erosions and even sleep disturbances) may be due to gastro-oesophageal reflux disease (GORD). In some cases, symptoms are triggered by an oesophageal reflex vagally mediated, while other symptoms are mainly related to the irritant effect of the refluxed material. The link with GORD is often difficult to establish because of the lack of typical digestive symptoms of GORD and of erosive oesophagitis in most of the cases. An empirical trial of double dose PPI therapy for 2 to 3 months can be done as the initial step in the diagnosis and treatment while oesophageal 24-hour pH monitoring is recommended by others to establish a temporal relationship between symptoms and reflux events. The optimal management algorithm remains to be determined. In some case, oesophageal luminal impedance monitoring could be useful to demonstrate a link between symptoms and a non-acid GORD. Traditionally, management of extra-oesophageal GORD manifestations relies on prolonged high doses of PPIs but the symptomatic efficacy of such treatment has been discussed recently. In case of adequate response, treatment can be tapered down to determine the minimal required maintenance dose. Anti-reflux surgery could be an alternative in some cases.

ENT symptoms of gastro-esophageal reflux are frequent. pH-impedance can detect acid and non-acid reflux and measure their proximal extension. The technique identifies the refluxate by changes in impedance. We discuss 2 clinical situations where correlation of symptoms could be explained by a non-acid reflux in the first case, and a lack of acid suppression in the second case, respectively. These results lead to a specific additional treatment to proton pump inhibitors (PPI). This technology provides a better understanding of the pathogenesis of reflux laryngitis, and affords the prescription of PPI on a proven diagnosis. Detection of non-acid reflux leads to an optimized medical treatment.
