Gastroesophageal reflux (GER) is a dysfunction of the distal esophagus causing movement of stomach contents into the esophagus. Patients may develop heartburn, regurgitation, dysphagia, odynophagia, and hemorrhage. Respiratory symptoms occur in 10-60 percent of patients with GER or hiatal hernia. Although there is evidence associating pulmonary symptoms and GER, causality has not been proven. The appropriate use of antireflux therapy or surgery to treat GER may consequently alleviate respiratory symptoms.

The aetiologic factors in gastro-oesophageal reflux disease include the free reflux of gastric juice, the composition of refluxed juice, the defensive mechanisms of the oesophagus, which are both mechanical and mucosal, and, sometimes, gastric abnormalities. Symptoms include heartburn, odynophagia, chest pain, dysphagia, regurgitation, and, occasionally, haemorrhage. Respiratory symptoms may occur. Diagnosis is based on determining the pressure and frequency of reflux (for which pH monitoring is preferred), testing for symptoms that may be caused by reflux, and assessing the degree of oesophagitis, for which endoscopy and histology are the only known techniques.

Respiratory symptoms were studied in 119 patients operated on for fundoplication and crural repair because of gastroesophageal reflux disease (GERD). The effect of antireflux surgery and of smoking habits on their respiratory symptoms was evaluated. A questionnaire was completed before and after surgery in connection with esophageal investigations. Chronic bronchitis was present in 20% of the patients, 38% of whom were smokers. In the rest of the patients, 18% were smokers. Cough was reported by 34% and expectoration by 21%. After surgery the number of patients with cough and chronic bronchitis was reduced significantly in nonsmokers and to some extent in smokers. It is believed that fundoplication with distal anchoring of the longitudinal esophageal muscle will improve pharyngoesophageal function and thereby decrease aspiration and respiratory symptoms due to mis-swallowing.

Respiratory symptoms in children may be associated with underlying gastro-oesophageal reflux (GOR). We reviewed the case notes of 20 children who presented to us from June 1993 to June 1994 with respiratory symptoms and GOR. The patients consisted of 16 Malays, two Chinese and two Indians with equal number of males and females. Their age at diagnosis was less than one year in 17 patients. The earliest age at presentation was at the third day of life. All patients had major respiratory manifestations i.e. recurrent wheezing, recurrent cough and pneumonia. In addition, three patients had stridor and six patients had apparent life threatening episodes (ALTE). Fourteen patients required ventilation because of respiratory failure. Diagnosis of GOR was based on clinical grounds supported by barium oesophagogram in seven patients and ultrasound examination in 11 patients. Eight patients were fundoplicated because of ALTE and recurrent severe bronchospasm. On follow up, 14 patients had hyperactive airways requiring inhaled bronchodilator and steroid therapy.

The association between asthma and gastroesophageal reflux (GER) has been further delineated with recent clinical investigations. The prevalence of GER development in asthmatics is higher than in control populations. Furthermore, asthmatics with GER have a higher risk of asthma hospitalization. Asthma medications may be one of the promoting factors for GER development in asthmatics. Inhaled albuterol decreases lower esophageal sphincter (LES) pressure and esophageal contraction amplitude. Furthermore, oral prednisone results in increased esophageal acid contact times. Respiratory symptoms also correlate with esophageal acid events. The role of neurogenic inflammation in asthma-induced bronchoconstriction is also being further developed. Therapy of GER may improve asthma outcomes in selected asthmatics. Currently, there are no double-blind, placebo-controlled, multicenter trials reporting asthma outcomes with antireflux therapy.

Gastroesophageal reflux disease can cause respiratory symptoms. These symptoms are triggered by reflux events that reach the pharynx, causing microaspiration or through vagal reflex. Respiratory symptoms can be vague and coexist with gastroesophageal reflux disease, without a real link between the two entities. To effectively treat these patients, it is important tofind an association between the two diseases. Work up should include the diagnosis of reflux disease, the diagnosis of pharyngeal reflux events--microaspiration--and, if possible, of laryngeal injury. Once the diagnosis has been established, an effective therapy must be offered to the patient. In these patients, medical treatment is less effective when compared to the results in the population with typical symptoms. This may be due to the fact that non-acid reflux episodes are causing the respiratory symptoms or as a result of an irreversible damage generated in the airway. Antireflux surgery is an effective therapy that reduces both acid and non-acid reflux events. This article describes the different diagnostic tests as well as the results obtained with surgical treatment in this population. Additionally, it describes potential applications of esophageal and pharyngeal impedance monitoring in these patients.

Respiratory symptoms might originate sometimes in the diseases of another thoracic organ than the lungs, the esophagus, which is able to determine sufferings mimicking pulmonary diseases. The authors review a series of esophageal diseases capable of generating respiratory symptoms, as well as the criteria for differential diagnosis: Zenker diverticulum, esophageal fistula, achalasia, cancer of the esophagus, esophageal cyst and gastro-esophageal reflux disease.

Although initial prognosis of oesophageal atresia is nowadays excellent with more than 95% of survival, the long-term complications are frequent. A gastro-oesophageal reflux is found in 26 to 75% of the cases, responsible for peptic oesophagitis, anastomotic stenosis and Barrett's oesophagus, risk factor of adenocarcinoma of the oesophagus. A dysphagia is frequently observed on these patients, sometimes several years after the surgery, observed in almost 45% of five-year-old children. Growth retardation is found in nearly a third of these children. Respiratory symptoms are particularly frequent, especially in the first years, associating tracheomalacia facilitating the bronchopulmonary infectious episodes (found in about 30% of 5-year-old children). Esotracheal fistula recurrence is very rare. A deformation of the rib cage is reported in 20%, and a scoliosis in 10% of the patients. However, the quality of life of these patients in the adulthood is good, and influenced by the existence of associated malformations. Even if the current prognosis of oesophageal atresia is good altogether, the frequency of the complications (digestive, respiratory, nutritional, orthopaedic) far from the initial intervention, and the necessity of a surveillance of the secondary oesophageal damages, justifies a systematic and multidisciplinary follow-up until adulthood.

Although after oesophageal atresia (OA) repair in infancy, respiratory problems are common, their natural history remains unclear. We assessed morbidity, pulmonary function (PF), and bronchial hyperresponsiveness (BHR) in adults with repaired OA respiratory. 588 patients who underwent surgery for OA during 1947-1985 were identified and those 262 who were alive and had their native oesophagus were included. Respiratory symptoms and respiratory symptom-related quality of life (RSRQoL) were assessed by questionnaire and interview, and the patients underwent spirometry, a histamine challenge test, and an exhaled nitric oxide test. For the questionnaires, we added 287 carefully matched general population-derived controls. Among the 101 (58 male) patients, median age 36 yrs (range 22-56 yrs), respiratory morbidity was significantly increased compared to controls. Patients had more respiratory symptoms and infections, as well as asthma and allergies, and more often impaired RSRQoL (p<0.001 for all). PF tests revealed restrictive ventilatory defect in 21 (21%) patients, obstructive ventilatory defect in 21 (21%) patients, and both in 36 (36%) patients. A total of 41 (41%) had BHR, and in 15 (15%), it was consistent with asthma. The most significant risk factors for restrictive ventilatory defect were thoracotomy-induced rib fusions (OR 3.4, 95% CI 1.3-8.7; p = 0.01) and oesophageal epithelial metaplasia (OR 3.0, 95% CI 1.0-8.9; p = 0.05). After repair of OA, respiratory-related morbidity, restrictive ventilatory defect and BHR extended into adulthood. Nearly half the patients had BHR and over half had a restrictive ventilatory defect. Thoracotomy-induced rib fusions and gastro-oesophageal reflux-associated oesophageal epithelial metaplasia were the strongest risk factors for restrictive ventilatory defect.

Most of the children operated for esophageal atresia will survive the neonatal period. However, medium-term and late complications are frequent in this population. Gastroesophageal reflux disease is observed in 26 to 75% of the cases and can be responsible for peptic esophagitis, anastomotic stenosis, and Barrett esophagus, which is a risk factor for adenocarcinoma of the esophagus. Dysphagia is frequently observed, sometimes several years after the surgery, affecting up to 45% of children at the age of 5 years. Growth retardation is present in nearly one-third of children at the age of 5 years. Ear, nose, and throat and respiratory complications are also very frequent but tend to improve with time. Tracheomalacia is found in 75% of these children at birth, sometimes responsible for severe complications (malaise, bradycardia). Respiratory symptoms are dominated by chronic cough, wheezing, and infections reported in 29% of the children by the age of 5 years. Restrictive, obstructive syndromes and bronchial hyperactivity can be observed, but usually remain moderate. All these complications can influence the patient's quality of life, which is moderately impaired compared to healthy controls. The high frequency of late sequelae in esophageal atresia justifies regular and multidisciplinary follow-up through adulthood.
