Hoarseness, asthma, and bronchitis are common but sometimes obscure manifestations of gastroesophageal reflux, the etiology of when respiratory symptoms predominate. In 300 consecutive patients who underwent surgical correction for gastroesophageal reflux, 129 (43%) had major respiratory complaints. Group 1 patients (82, 64%) were those referred for respiratory problems alone. In Group 2 (patients referred because of peptic complaints), 47 had associated respiratory problems in various combinations, including an additional 10 patients who had bronchiectasis. Treatment with appropriate surgical resection, in addition to antireflux procedures, was carried out in these people. Noticeable relief of respiratory symptoms was obtained in 96 (74%) of the 129 patients; 30 were improved and 2 were unchanged. Recurrent hiatus hernia or esophagitis was documented in 21 (7%) of the 300 patients.

Hoarseness is not generally appreciated to be a manifestation of pediatric gastroesophageal reflux. We describe a case in which treatment of well-documented gastroesophageal reflux and esophagitis in a young girl with hoarseness and nocturnal cough led to resolution of these symptoms. Possible pathogenetic mechanisms and the difficulty in associating hoarseness with reflux by standard reflux testing are discussed.

In an attempt to ascertain radiologic efficacy in patients with evidence of gastroesophageal reflux disease (GERD) at pH testing, radiographic findings were correlated with pH values obtained with an esophageal monitor worn for a 24-hour period in 112 patients. Fifteen (30%) of 50 patients with abnormal pH test results had esophagitis diagnosed radiographically, compared with six (10%) of 62 with normal pH test results (P < .05). The severity of abnormal pH monitoring results was classified but did not correlate significantly with the prevalence of esophagitis diagnosed radiographically. Hiatal hernia was also more common (80% vs 60%) in patients with abnormal pH test results (40 of 50 patients) than in those with normal results (37 of 62 patients) (P < .05). Pharyngeal, laryngeal, and pulmonary symptoms were common indications for evaluation, and 14 of 27 (52%) patients with hoarseness had an abnormal pH tracing. Only a minority of patients with evidence of GERD as defined by abnormal pH test results had reflux esophagitis diagnosed radiographically.

The frequency and the possible age-related characteristics of gastro-oesophageal reflux disease (GORD) were investigated in 195 consecutive elderly subjects (mean age 74 years), referred to endoscopy for abdominal symptoms or sideropenic anaemia. In the 105 of these patients in whom there was any suspicion of GORD, 24-hour pH monitoring was carried out. All the patients were interviewed before the examinations. Erosive or complicated (grade 2-4) oesophagitis was found in 18% of patients. The main symptoms in these patients were dysphagia, respiratory symptoms and vomiting. Chronic cough, hoarseness or wheezing were present in 57% of patients with oesophagitis compared with 33% of those without oesophagitis (p less than 0.001). The occurrence of heartburn and regurgitation did not differ significantly between patients with or without oesophagitis, although the mean symptom scores were higher in those with oesophagitis. Dyspepsia and chest pain were not typical symptoms in oesophagitis. Of patients with oesophagitis 29% had no typical symptoms of GORD; only 24% of patients with regurgitation had oesophagitis. In 24-hour pH monitoring, a significant increase in the occurrence of symptoms was not seen until total reflux time pH less than 4 exceeded 10%. The occurrence of heartburn did not correlate with the extent of reflux in the pH study. In conclusion, typical symptoms of GORD in the aged were regurgitation, dysphagia, respiratory symptoms and vomiting rather than heartburn.

Occult (silent) gastroesophageal reflux disease (GER, GERD) is believed to be an important etiologic factor in the development of many inflammatory and neoplastic disorders of the upper aerodigestive tract. In order ot test this hypothesis, a human study and an animal study were performed. The human study consisted primarily of applying a new diagnostic technique (double-probe pH monitoring) to a population of otolaryngology patients with GERD to determine the incidence of overt and occult GERD. The animal study consisted of experiments to evaluate the potential damaging effects of intermittent GER on the larynx. Two hundred twenty-five consecutive patients with otolaryngologic disorders having suspected GERD evaluated from 1985 through 1988 are reported. Ambulatory 24-hour intraesophageal pH monitoring was performed in 197; of those, 81% underwent double-probe pH monitoring, with the second pH probe being placed in the hypopharynx at the laryngeal inlet. Seventy percent of the patients also underwent barium esophagography with videofluoroscopy. The patient population was divided into seven diagnostic subgroups: carcinoma of the larynx (n = 31), laryngeal and tracheal stenosis (n = 33), reflux laryngitis (n = 61), globus pharyngeus (n = 27), dysphagia (n = 25), chronic cough (n = 30), and a group with miscellaneous disorders (n = 18). The most common symptoms were hoarseness (71%), cough (51%), globus (47%), and throat clearing (42%). Only 43% of the patients had gastrointestinal symptoms (heartburn or acid regurgitation). Thus, by traditional symptomatology, GER was occult or silent in the majority of the study population. Twenty-eight patients (12%) refused or could not tolerate pH monitoring. Of the patients undergoing diagnostic pH monitoring, 62% had abnormal esophageal pH studies, and 30% demonstrated reflux into the pharynx. The results of diagnostic pH monitoring for each of the subgroups were as follows (percentage with abnormal studies): carcinoma (71%), stenosis (78%), reflux laryngitis (60%), globus (58%), dysphagia (45%), chronic cough (52%), and miscellaneous (13%). The highest yield of abnormal pharyngeal reflux was in the carcinoma group and the stenosis group (58% and 56%, respectively). By comparison, the diagnostic barium esophagogram with videofluoroscopy was frequently negative. The results were as follows: esophagitis (18%), reflux (9%), esophageal dysmotility (12%), and stricture (3%). All of the study patients were treated with antireflux therapy. Follow-up was available on 68% of the patients and the mean follow-up period was 11.6 +/- 12.7 months.(ABSTRACT TRUNCATED AT 400 WORDS)

The exact incidence of gastroesophageal reflux (GER) is unknown, although it is estimated that at least 25% of patients with GER have head and neck symptoms alone. These symptoms may consist of one or more of the following: excess salivation, hoarseness, "post-nasal drip," voice change, persistent coughing, food sticking in the throat, globus hystericus, otalgia, throat clearing, neck pain, sore throats, the sensation of a lump in the throat, choking spells, and bronchospasm. Carcinoma of the larynx and upper aerodigestive tract may be a consequence of chronic reflux. GER, especially when the classic symptoms of reflux are absent, is frequently overlooked as a cause of these problems. This article reviews the symptoms and pathophysiology of these conditions. The diagnostic and therapeutic modalities available to us in managing these patients are also discussed.

In a number of patients there is evidence of an unfavourable interaction between gastro-oesophageal reflux (GER) and pulmonary disease, that takes the form of a vicious circle: first GER can induce and maintain chronic bronchopulmonary inflammation by recurrent unnoticed aspirations and, secondly chemical irritation of the oesophageal mucosa causes airway obstruction by vagally-mediated reflexes. Obstructive airway disease in turn favours GER via anatomical functional and physiological factors. Thus the prevalence of GER is increased to 30-40% in patients with asthma and chronic bronchitis, as compared with only 5-10% in the general population. A positive history of productive cough, nocturnal respiratory symptoms and recurrent hoarseness may be helpful in detecting an important relationship between GER and chronic airway disease. The modified Bernstein-test, radionuclide studies and detailed sleep studies are suitable methods of establishing the diagnosis. Antireflux diets, H2-antagonists and antacids are accepted treatment in the adult, and may obviate surgical procedures in most patients. In clinical practice the relationship between GER and pulmonary diseases should be considered routinely, in order to initiate early and effective treatment and to end the vicious circle.

Gastroesophageal reflux disease is a common problem that frequently presents with atypical complaints including nausea, hiccups, globus sensation, chest pain, hoarseness, coughing, or various pulmonary complaints. Diagnosis may be difficult, as these patients often do not have radiographic or endoscopic evidence of esophagitis. In these difficult cases, prolonged esophageal pH monitoring provides an accurate method of quantitating acid reflux parameters and correlating symptoms with reflux episodes in an outpatient setting. Current equipment is compact, durable, and not difficult to use or extremely expensive. Data analysis, with a particular emphasis on acid-exposure time (total, upright, supine), reliably discriminates between abnormal and normal subjects but it is not a perfect "gold standard" for gastroesophageal reflux disease. Indications for esophageal pH monitoring include: (1) atypical symptoms of acid reflux with normal endoscopy, (2) typical reflux symptoms unresponsive to medical therapy, and (3) the follow-up of reflux disease after either medical or surgical therapy. This test is currently performed primarily by gastroenterologists, but we believe many other groups may find this technology helpful. To meet these expanding applications, test refinements are necessary, particularly easier methods of placing the pH probe and better standards for defining abnormal pH parameters in older patients. The future for esophageal pH monitoring is bright. This technology has the potential to do for the diagnosis of gastroesophageal reflux disease what endoscopy has done for the diagnosis of peptic ulcer disease.

The symptoms and presentations of gastroesophageal reflux disease are rather numerous. These include the typical symptoms, such as heartburn, regurgitation, water brash, or dysphagia. However, reflux may also be responsible for such symptoms as hoarseness, pulmonary aspiration, or asthma. It may also be an important cause of noncardiac chest pain. Thus, gastroesophageal reflux disease may be considered a disease with more than just "esophageal" symptoms.

Ten patients referred by an otolaryngologist for ambulatory esophageal pH monitoring for suspected reflux-induced hoarseness were monitored with a dual ambulatory pH system in which probes were simultaneously placed 5 cm above the lower esophageal sphincter and 2 cm above the upper esophageal sphincter (laryngeal inlet). All were nonsmokers. Hypopharyngeal reflux (pH drop less than 4 in upper electrode preceded by pH drop less than 4 in esophageal electrode) was conclusively demonstrated in 7 of 10 patients. Three of these seven patients had normal frequency and duration of esophageal reflux and would have been classified as normal, yet demonstrated acid reflux into the hypopharynx. As a group, these patients were high frequency, short duration, upright refluxers. Combined hypopharyngeal and esophageal pH monitoring is useful in the diagnosis of reflux-induced hoarseness.
