Gastroesophageal reflux disease (GERD) is a common medical condition affecting approximately 35-40% of the adult population in the western world. The role of GERD in causing extra-esophageal symptoms including laryngitis, asthma, cough, chest pain, and dental erosions is increasingly recognized with renewed interest among gastroenterologists and other specialists. Direct injury by mucosal contact, and vagally mediated reflex from distal esophageal acid exposure are the two possible mechanisms by which reflux-related extra-esophageal tissue injuries may occur. Several investigational techniques may be used to diagnose gastroesophageal reflux; however, because of the poor sensitivity of endoscopy and pH monitoring, and the poor specificity of laryngoscopy, empiric therapy with proton-pump inhibitors (PPI) is now considered the initial diagnostic step in patients suspected of having GERD-related symptoms. In those who improve with such therapy, it is likely that GERD may be the cause of the extra-esophageal presentation. In those who are unresponsive to such therapy, other diagnostic testing such as impedance/pH monitoring may be reasonable in order to exclude continued acid or weakly acid reflux. However, PPI-unresponsive patients usually have causes other than GERD for the extra-esophageal symptoms and signs.

Esophagitis, ulcer with potential for bleeding and peptic stenosis are typical complications of gastroesophageal reflux disease (GERD). Whereas GERD is frequent with symptom prevalence of 30 % in the normal population, ulcer and peptic stenosis have become very rare. Consequently surgical interventions due to these complications are only necessary in exceptional cases. After successful bougienage and response to adequate medical treatment, surgical indications for peptic stenosis or ulcer are not different to those for other forms of reflux disease. GERD patients with a "short esophagus" and axial hiatal hernia are difficult to treat either by medication or surgery. However, intrathoracic fundoplication may lead to acceptable results. Extraesophageal manifestations of GERD are caused by a severe reflux up to the cervical esophagus. The resulting laryngitis or pulmonary problems require antireflux surgery more often than in the absence of these symptoms. Long-standing reflux can lead to the development of Barrett mucosa, which represents a precancerous for esophageal adenocarcinoma and can be considered as a special complication of GERD. Retrospective data show that progression of Barrett mucosa or its malignant degeneration cannot be prevented by fundoplication. However, in a comparative study concerning low-grade neoplasia fundoplication leads to significantly more cases with regression than medication. High-grade neoplasia has to be removed in all cases. With regard to the prerequisite for correct indications the long-term results of endoscopic or surgical procedures are equal, but endoscopic mucosectomy is favoured due to its lower invasiveness. Indications for surgery by limited or radical esophagectomy are incomplete removal of neoplasia after mucosectomy, long Barrett's esophagus with multifocal lesions or suspicion of submucosal carcinoma.

Laryngeal signs and symptoms are frequently associated with gastroesophageal reflux disease (GERD). Establishing the diagnosis of laryngopharyngeal reflux (LPR), however, is enigmatic as there are no tests that specifically define GERD-related laryngitis. Furthermore, in contrast to typical GERD, the treatment data for LPR using acid suppression with proton pump inhibitors has not shown a statistically significant advantage over placebo. This review highlights the current challenges for establishing the diagnosis of GERD-related LPR and focuses on the limitations of medical therapy directed toward gastric acid suppression.

Chronic laryngeal signs and symptoms associated with gastroesophageal reflux disease (GERD) are often referred to as reflux laryngitis or laryngopharyngeal reflux (LPR). It is estimated that up to 15% of all visits to otolaryngology offices are because of manifestations of LPR. Damage to laryngeal mucosa may be the result of reflux of gastroduodenal contents, whether chronic or a single incident. The most common presenting symptoms of LPR include hoarseness, sore throat, throat clearing, and chronic cough. The diagnosis of LPR is usually made on the basis of presenting symptoms and associated laryngeal signs, including laryngeal edema and erythema. The current recommendation for managing these patients is empiric therapy with twice-daily proton pump inhibitors for 1 to 2 months. Other causes of laryngeal irritation are considered in most of those who are unresponsive to such therapy. Surgical fundoplication is most effective in those who are responsive to acid-suppressive therapy.

Gastroesophageal reflux disease typically manifests as heartburn and regurgitation, but it may also present with atypical or extraesophageal symptoms, including asthma, chronic cough, laryngitis, hoarseness, chronic sore throat, dental erosions, and noncardiac chest pain. Diagnosing atypical manifestations of gastroesophageal reflux disease is often a challenge because heartburn and regurgitation may be absent, making it difficult to prove a cause-and-effect relationship. Upper endoscopy and 24-hour pH monitoring are insensitive and not useful for many patients as initial diagnostic modalities for evaluation of atypical symptoms. In patients with gastroesophageal reflux disease who have atypical or extraesophageal symptoms, aggressive acid suppression using proton pump inhibitors twice daily before meals for three to four months is the standard treatment, although some studies have failed to show a significant benefit in symptomatic improvement. If these symptoms improve or resolve, patients may step down to a minimal dose of antisecretory therapy over the following three to six months. Surgical intervention via Nissen fundoplication is an option for patients who are unresponsive to aggressive antisecretory therapy. However, long-term studies have shown that some patients still require antisecretory therapy and are more likely to develop dysphagia, rectal flatulence, and the inability to belch or vomit.

Helicobacter pylori (H. pylori) is one of the frequently encountered micro-organisms in the aerodigestive tract. Although infections caused by H. pylori are this common, the exact mode of transmission has not been fully understood yet. Oral-oral, fecal-oral and gastrointestinal-oral routes are the possible modes of transmission. This infection is usually acquired in childhood and may persist for the whole life of the patient. However, about 80% of the infected humans are asymptomatic. Human stomach was considered to be the only reservoir of H. pylori until bacteria were discovered in human dental plaque, in oral lesions, in saliva, in tonsil and adenoid tissue. It is suggested that H. pylori enters the nasopharyngeal cavity by gastroesophageal reflux and colonize in the dental plaques, adenoid tissues and tonsils. From these localizations, the bacteria ascend to the middle ear and to the paranasal sinuses directly or by the reflux again and may trigger some diseases, including otitis, sinusitis, phyrangitis, laryngitis and glossitis. But still, the exact mechanism remains unclear.

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.

The manifestations of gastroesophageal reflux disease (GERD) have been classified into either esophageal or extraesophageal syndromes. Cough, reflux laryngitis, and asthma have been classified as extraesophageal syndromes, whereas reflux chest pain has been classified as a symptomatic syndrome of GERD. In extraesophageal syndromes, patients usually do not display the classic symptoms of reflux, such as heartburn and regurgitation. Upper gastrointestinal endoscopy and pH monitoring, when used to diagnose reflux in patients with symptoms not classic for GERD, have proved to have poor sensitivity and are often not diagnostically helpful. In contrast, an empiric trial of proton pump inhibitors is a well-established, cost-effective tool.

Gastroesophageal reflux disease (GERD) often presents as typical symptoms such as heartburn or acid regurgitation. However, a subgroup of patients presents a collection of symptoms and signs that are not directly related to esophageal damage. These are known collectively as the extraesophageal manifestations of GERD, such as non-cardiac chest pain, laryngitis, chronic cough, hoarseness, asthma or dental erosion. They have a common pathophysiology, involving microaspiration of acid into the larynx and pharynx, and vagally mediated bronchospasm and laryngospasm. The role of extraesophageal reflux in such disorders is underestimated due to often silent symptoms and difficult confirmation of diagnosis. Endoscopy and pH monitoring are insensitive and therefore not useful in many patients as diagnostic modalities. Thus, anti-secretory therapy by proton pump inhibitor is used as both a diagnostic trial and as a therapy in the majority. Attention to optimizing therapy and judicious use of endoscopy and reflux monitoring are needed to maximize treatment success.

A global evidence-based consensus has defined gastroesophageal reflux disease (GERD) as 'a condition, which develops when the reflux of stomach contents causes troublesome symptoms and/or complications.' The manifestations of GERD can be divided into esophageal and extraesophageal syndromes, and include vomiting, poor weight gain, dysphagia, abdominal or substernal/retrosternal pain, esophagitis and respiratory disorders. The extraesophageal syndromes have been divided into established and proposed associations: established would include cough, laryngitis, asthma and dental erosion ascribable to reflux, whereas proposed associations would include pharyngitis, sinusitis, idiopathic pulmonary fibrosis and recurrent otitis media. Uninvestigated patients with esophageal symptoms without evidence of esophageal injury would be considered to have asymptomatic esophageal syndromes, whereas those with demonstrable injury are considered to have esophageal syndromes with esophageal injury. Therefore, this allows symptoms to define the disease but permits further characterization if mucosal injury is found. Within the syndromes with associated injury are reflux esophagitis, stricture, Barrett's esophagitis and adenocarcinoma. This review will address definitions of GER and GERD-associated symptoms and treatment options.
