The incidence of aspiration, the causative esophageal pathophysiology, and the results of surgical therapy were evaluated in 100 patients with abnormal gastroesophageal reflux documented by 24-hour esophageal pH monitoring. Based on historical evidence, 48 patients were suspected to be aspirators. Eight patients had documented episodes of aspiration (drop on esophagela pH, followed by acid taste in mouth and onset of cough or wheezing spell) during the monitoring period. Nine patients were considered to be potential aspirators because they presented oral acid regurgitation without development of pulmonary symptoms. In five patients a primary respiratory disorder (PRD) induced gastroesophageal reflux. The remaining 78 patients had abnormal reflux without aspiartion or regurgitation. Aspirators had a 75% incidence of esophageal motor abnormality on manometry, and the clearance of refluxed acid was significantly delayed in the supine position. A history of heartburn and endoscopic evidence of esophagitis were present in only half of the patients who were documented aspirators. Potential aspirators were spared from aspiration by rapid esophageal clearance of refluxed acid unaffected by changes in body position. Patients with a PRD had higher distal esophageal segment (DES) pressure and normal esophageal motility with minimal esophagitis. Nonaspirators significantly improved their clearance while in the supine position, emphasizing the protective effect of esophageal peristalsis against aspiration. An antireflux procedure in five aspirators raised the DES pressure significantly and returned the reflux status to normal by 24-hour pH-monitoring standards. The incidence of aspiration appears to be less than that suspected by history and is due to a motor disorder that interferes with the ability of the esophagus to clear reflex acid. Abnormal pulmonary symptoms can induce or result from gastroesophageal reflux and, when the latter occurs, an antireflex procedure stops both reflux and aspiration.

Eight lesser known reflexes were grouped together because of their anatomical and physiological relationship. In all of them a branch of the vagus nerve forms a bridge between a circumscribed area of the skin, mostly the external auditory meatus, and an internal organ, namely the stomach, esophagus, lungs, heart, uterus, and some male and female sex organs. The eight reflexes are: (1) Gastroauricular phenomenon (Gaph) (Engel, 1922) in man; (2) Auricular phenomenon (Malherbe, 1958) in man; (3) Pulmonoauricular phenomenon (Deutsch, 1919) in man; (4) Auriculogenital reflex (Bradford, 1937) in cat; (5) Auriculouterine reflex (Vasiliu, 1932) in women; (6) Oculocardiac reflex (Aschner, 1967) in man; (7) Kalchschmidt's reflex in cattle (1956); and (8) Coughing attack with heartburn (Berlin, 1959) in man. The organs involved are either effector or receptor organs. The six reflexes observed in man are of diagnostic significance. Attention is also drawn to analogous reflexes in which the meningeal branch of the vagus is involved.

A patient, an 80-year-old female, had complained of a cough for 20 weeks, and was not cured by cough medicine. Gastroesophageal reflux was considered as the cause of the cough because of her symptoms and gastrointestinal fiberscopy (GIF) and barium meal studies. She made favorable progress on a histamine H2 blocker and cysapurid for 4 weeks. Therefore we diagnosed her cough as caused by gastroesophageal reflux. We also studied the incidence of chronic persistent cough in patients suspected of gastroesophageal reflux because of symptoms and GIF results. Among 676 cases examined by GIF at Niigata-kenritsu Myoko Hospital, we detected 7 cases who complained of heartburn and in whom we observed hiatal hernia and reflux esophagitis by GIF. Only one of them, the present case, complained of a cough. CPC caused by gastroesophageal reflux is not seen frequently, but the possibility of GER as the cause of CPC should be considered.

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)

A questionnaire study was conducted to assess the prevalence and severity of symptoms suggestive of esophageal disorders in a general population. The study included 407 randomly selected subjects, evenly distributed in terms of sex and age, within the age span of 20-79 years. A total of 337 subjects replied (85%). Symptoms suggestive of gastroesophageal reflux were found among 25% of the participants. Cough on swallowing was common (27%), as was globus (16%) and chest pain (13%). In addition, dysphagia was reported by 10% and vomiting by 9%. The symptoms were usually mild, and moderate to severe symptoms were reported only occasionally (1-4%). No statistical correlation was found between esophageal symptoms and age, sex, or the reported consumption of tobacco, alcohol, or non-steroidal anti-inflammatory drugs. The frequency of heartburn and/or acid regurgitation was twice as common among those with symptoms of respiratory disease as among those with no respiratory complaints. A stepwise logistic regression analysis showed that a chronic cough and/or breathing difficulties were significantly related to the presence of symptoms suggestive of gastroesophageal reflux.

Nocturnal gastro-oesophageal reflux is known to be particularly damaging to the oesophageal mucosa, being associated with stricture formation and columnarisation. At present, this can only be detected by prolonged intra-oesophageal pH monitoring. A total of 50 patients with endoscopic oesophagitis were evaluated by ambulatory pH monitoring to detect the presence of nocturnal reflux. Whether certain symptoms in the presence of a hiatal hernia would identify those patients with reflux at night was investigated. Thirty-three patients had nocturnal reflux, two-thirds of whom had a hiatal hernia. Heartburn at night was of limited value (specificity = 65%) in detecting acid reflux whereas regurgitation and cough showed greater specificity (88% and 100% respectively) but lacked sensitivity (45% and 12% respectively). The combination of nocturnal symptoms and a hiatal hernia in patients with endoscopic oesophagitis correctly identified 58% of patients with nocturnal reflux and was highly specific (100%). This study has confirmed that symptoms and endoscopic findings can detect a significant proportion of 'at risk' patients, but the remainder will require pH monitoring to assess their pattern of acid exposure.

This study was carried out on 104 patients of whom 94 were asthmatic and 10 patients presented with a spasmodic intractable cough; all presented with symptoms evocative of an associated gastro-oesophageal reflux (RGO). The clinical symptoms revealed a nocturnal cough (67%), cough preceeding asthma (46%) and heartburn in 60%. The asthma was severe (type III and IV in 89% of cases), or dependent on corticosteroids (37% of cases). pH monitoring of the oesophagus is the most sensitive examination (88% with positive results) slightly ahead of manometry and scintigraphy (both 81%), these examinations were clearly superior to radiographic examination (49%) and oesophageal fibroscopy (36%). The combination of pH monitoring and of scintigraphy enabled 98% of RGO cases to be identified by their clinical data. Medical treatment with Tagamet, Gaviscon and Primperan (alone or in combination) produced an improvement in the respiratory symptoms in 50% of the cases. Of the 14 surgically treated, 7 obtained an improvement in their respiratory symptoms. Seven of the ten patients with spasmodic cough were improved by medical treatment. Our study shows the frequency of oesophageal reflux in patients with severe asthma. In half of them RGO intervened as an aggravating factor and the medical treatment of RGO led to a clear improvement in the respiratory symptoms.

Although gastro-esophageal reflux (GER) is one of the major causes of chronic persistent cough (CPC) in the USA and in Europe, it is a rare cause of CPC in Japan. We report a rare case of CPC caused by GER, in which treatment with an H2-blocker or with a proton pump inhibitor was successful. A 65-year-old woman had complained of coughing for over 25 years. Her coughing was not alleviated by treatment with a bronchodilator (beta 2-adrenoceptor agonist), an anti-allergic agent, a corticosteroid, or a sedative. GER was considered as a possible cause of her coughing because exacerbation of the coughing was associated with the development of gastrointestinal symptoms (heartburn). Fiberoptic esophagoscopy showed esophagitis and esophageal herniation of the sliding type. Twenty four-hour monitoring of distal esophageal pH showed that the coughing occurred when the pH dropped below 4, and that the pH was less than 4 for about 7% of the whole monitoring time. An H2-blocker or a proton pump inhibitor completely eliminated the symptoms. Therefore, CPC caused by GER was diagnosed. We found that coughing could be induced by instillation of 0.1 N hydrochloric acid at the distal esophagus, and that the coughing was partially inhibited by inhalation of an anti-muscarinic agent (ipratropium bromide) and by esophageal instillation of 4% xylocaine. These data support the "reflex theory". Although CPC caused by GER is rare in Japan, we should remember that GER can be a cause of CPC even in Japanese patients.

Gastroesophageal reflux may be responsible for atypical symptoms such as chronic cough and hoarseness. Our aim was to evaluate and treat patients with severe gastroesophageal reflux and chronic cough or hoarseness with intensive antireflux therapy. Twenty-seven patients with typical heartburn symptoms in addition to significant cough or hoarseness were treated with aggressive antireflux therapy. We recorded the response of each symptom to the antireflux therapy. Two patients were lost to follow-up. Twenty of the 25 (80%) patients showed some improvement in cough or hoarseness, nine (36%) had no atypical symptoms at follow-up. The response of heartburn to therapy was strongly predictive of successful therapy for the atypical symptoms. Cough and hoarseness improved in only two of the five patients with residual heartburn symptoms compared to 18 of 20 patients with no heartburn (P < 0.04). Only patients with no heartburn symptoms at follow-up had complete resolution of atypical symptoms. There were no important differences on ambulatory pH monitoring between partial and complete responders. Improvement in atypical reflux symptoms, such as chronic cough and hoarseness, is common with aggressive antireflux therapy. There are no findings on ambulatory esophageal pH monitoring that uniquely identify patients who are likely to respond to antireflux therapy.

Heartburn and epigastric pain are the leading symptoms of reflux disease. Next to other symptoms like pharyngeal burning, regurgitation and retrosternal pain, chronic hoarseness and coughing as well as angina pectoris symptoms may point towards a pathological reflux. In endoscopically verified reflux esophagitis proton pump inhibitors are the treatment of first choice. Aim of therapy is loss of symptoms, healing of epithelial defects and prevention of Barrett's esophagus. If a columnar epithelium-lined esophagus is seen, surveillance is recommended in one- or two-year intervals.
