Between 1980 and 1989, 15 of 46 patients (11 children, 4 adults) who underwent suboccipital craniectomy and cervical laminectomy for symptomatic Chiari malformations presented with manifestations of neurogenic dysphagia. Each of these patients had normal swallowing function before the development of dysphagic symptoms. Dysphagia was progressive in all 15 and, in most cases, preceded the onset of other severe brain stem signs. The rate of symptom progression varied depending on the age of the patient. Whereas the six infants (all Chiari II) deteriorated rapidly after the onset of initial symptoms, the five older children (two Chiari I, three Chiari II) and four adults (all Chiari I) showed a more gradual deterioration. In 11 patients with severe dysphagia, barium video esophagograms, pharyngoesophageal motility studies, continuous esophageal pH monitoring, and appropriate scintigraphic studies were useful in defining the scope of the swallowing impairment and determining whether perioperative nasogastric or gastrostomy feedings, gastric fundoplication, and/or tracheostomy were needed to maintain adequate nutrition and avoid aspiration. These patients all had widespread dysfunction of the swallowing mechanism, with a combination of diffuse pharyngoesophageal dysmotility, cricopharyngeal achalasia, nasal regurgitation, tracheal aspiration, and gastroesophageal reflux. The pathophysiology of these swallowing impairments and their relation to the hindbrain malformation is discussed. Postoperative outcome with regard to swallowing function correlated with the severity of preoperative symptoms. The four patients with mild dysphagia showed rapid improvement in swallowing function after surgery. Seven patients with more severe impairment but without other signs of severe brain stem compromise, such as central apnea or complete bilateral vocal cord paralysis, also improved, albeit more slowly. In contrast, the outcome in the four patients who developed other signs of severe brain stem dysfunction before surgery was poor. Early recognition of neurogenic dysphagia and expeditious intervention are therefore crucial in ensuring a favorable neurological outcome.

Nonobstructive dysphagia is a common symptom of gastroesophageal reflux disease, and may be present in up to 45% of patients. To elucidate the mechanism of dysphagia, stationary and ambulatory motility studies were performed in 10 controls and 27 patients with gastroesophageal reflux disease. Sixteen patients had nonobstructive dysphagia and 11 had no dysphagia. During stationary studies, there was essentially no difference in esophageal body motility among all the groups. Lower esophageal sphincter manometry was similar in patients with or without dysphagia. On ambulatory motility, about 40% of contractions in the body of the esophagus were simultaneous in the supine position in controls and both groups of patients. The rate of simultaneous contractions decreased in the upright position and at mealtimes in controls and in patients without dysphagia, but not in those with dysphagia. This resulted in a higher percentage (38%) of intraprandial simultaneous wave activity in patients with dysphagia than in those without dysphagia (23%) or in controls (13%) (p less than 0.05). Patients with reflux disease who suffer from nonobstructive dysphagia therefore have a motility disorder measurable on ambulatory motility studies which results in an increased percentage of nonperistaltic (simultaneous wave) activity during mealtimes.

Fifty-two patients with gastro-oesophageal reflux disease refractory to medical treatment were randomized to undergo a Nissen total (360 degrees wrap) or Lind partial (300 degrees wrap) transabdominal fundoplication. Each group was comparable in number (26 patients), mean age (47 and 48 years) and sex distribution (eight women). Preoperative and postoperative assessment involved a modified Visick score, 22-h intraoesophageal pH monitoring, endoscopy and manometry. Follow-up was at 6 weeks and between 3 and 33 (mean 13) months. The prevalence of heartburn and regurgitation and the results of pH monitoring improved significantly after both operations (P less than 0.001). At early assessment eight previously asymptomatic patients (31 per cent) from the Nissen group and six (23 per cent) from the Lind group experienced difficulty swallowing. Ten patients (38 per cent) in each group complained of 'gas bloat'. Both complications had improved at late assessment in the majority of patients. No statistically significant advantage could be demonstrated for either operation.

Severe feeding troubles were recorded in five babies with long-gap esophageal atresia who underwent, between 1985 and 1990, a delayed primary anastomosis after spontaneous growth of their esophageal stumps. A comparison with 20 cases of direct esophageal anastomosis, operated on in the same period, was carried out by means of recorded esophagrams, pH monitoring and questionnaires charting the growth pattern and feeding habits of the patients. Bottle feeding, and, later on, the introduction of semi-solid foods was significantly retarded in the group of children with delayed primary anastomosis (labeled as group B) as well as height and weight parameters. Failure to complete feeds, dysphagia, vomiting, coughing, choking and recurrent respiratory symptoms were also significantly more common in this group than in the primary anastomosis group (labeled as group A) even in the absence of stricture. Variable degrees of disordered esophageal motility were present in all patients but pooling of the contrast medium, retrograde flow and delayed clearing of the esophagus were more frequent in group B. No patient was shown to have associated hiatal hernia. A 24 hour pH recording showed severe gastroesophageal reflux in 4 out of 13 cases of group A and in 3 out of 5 cases of group B. Clearing times were significantly delayed in all refluxing children. Our data suggest that the retarded start of oral feeding and swallowing coordination in patients with delayed primary anastomosis add further negative factors to their congenitally impaired esophageal motility, causing protracted dysphagia which represents a major problem for both family and hospital staff.

End-to-side anastomosis (ES) and ligation of the tracheoesophageal fistula (TEF) has been the procedure of choice for esophageal atresia at our institution since 1967. This report summarizes our operative and long-term results with the ES operation in 68 babies, including 33 in Waterston group A (50%), 23 in group B (35%), and 12 in group C (15%). An additional 10 patients had a primary end-to-end (EE) anastomosis, while 14 others required either staged EE repair or an esophageal replacement procedure. Overall survival rate with ES was 93% including two deaths attributed to major anastomotic leaks and sepsis, and three others in group C from cardiac anomalies. Six (9%) of those having ES anastomosis developed a recurrent TEF between 40 days and 21 months of age, necessitating reoperation. Predisposing factors to recurrent TEF were surgical inexperience (three cases; first operation for each surgeon), forceful vomiting secondary to gastroesophageal reflux (GER) in two, and drug overdose in one. Anastomotic leak occurred in seven (10%) following end-to-side repair and was implicated in two deaths. Three patients developed minor anastomotic stricture requiring less than three dilatations, while one with a tight stricture needed as many as five dilatations over the first 14 months of life. Mild dysphagia and respiratory symptoms were uniformly observed during the first year, but only five patients (7%), including the two with recurrent TEF, required fundoplication for persistent GER. All patients were eating table foods after 1 year of age, while 10 (15%) have required periodic endoscopic removal of solid food lodged at the radiographically unobstructed anastomosis.(ABSTRACT TRUNCATED AT 250 WORDS)

While an alkaline component to esophageal reflux disease is known to be present, little is known about its etiology and harmful effects. Simultaneous gastric and esophageal 24-hour pH monitoring was performed in 81 patients with foregut symptoms. The presence of a mechanically defective lower esophageal sphincter was determined by manometry and duodenogastric reflux by computer-assisted discriminant analysis of the gastric pH record. Heartburn, dysphagia, and regurgitation occurred more frequently in those with a mechanically defective sphincter (p < 0.05) and epigastric pain in those with duodenogastric reflux (p < 0.05). Esophagitis was more common and severe in those with a mechanically defective sphincter (p < 0.05). In these patients, the percentage of time over 24 hours that the esophageal pH was less than 4 was 40.5% in patients without duodenogastric reflux but only 10.2% in those with duodenogastric reflux (p < 0.005), suggesting acid damage in the former and alkaline damage in the latter. To establish the origin of the esophageal alkaline exposure, episodes of elevated fasting gastric pH greater than 4 lasting longer than 1 minute were searched for and identified in 45 patients. Esophageal pH tracings were compared for 30 minutes before and after these events. The esophageal pH was higher following these episodes in duodenogastric reflux patients (p < 0.05), suggesting a gastroduodenal origin of the esophageal alkalinization. This study shows that esophageal damage may be due to acid or alkaline reflux. The alkaline component of gastroesophageal reflux is important and should be considered in the evaluation of patients with foregut symptoms so that appropriate medical or surgical therapy can be instituted.

We have studied for periods averaging 111 months 16 survivors out of a series of 20 children treated for oesophageal atresia (EA) by neonatal end-to-end anastomosis. Twelve of them had gastroesophageal reflux (GER) manifested by either digestive (vomiting, dysphagia, pyrosis, haemorrhage or foreign body impaction) or respiratory symptoms (repeated neumoniae or frequent u.r.i.). pH-studies decealed very increased acid exposure in these patients. Manometric studies showed disorganized peristalsis with near-absence of propulsive waves and predominance of mass-contractions. Interestingly both lower esophageal sphincter pressure and length were normal. Five children had histological esophagitis and 2 had Barrett's esophagus. Seven patients have had an anti-reflux procedure and two more should be operated in the near future. Our experience reveals that GER incidence in EA is very high, that esophageal function is severely impaired in this condition, that mucosal lesions can be serious and that funduplication is effective. Since it has been demonstrated that esophageal dysfunction in EA patients is due to structural anomalies, spontaneous improvement should not be expected in them and surgical treatment should be largely indicated. EA patients require long-term gastro-enterologic follow-up.

The effects of the Angelchik prosthesis on esophageal and gastric function were investigated in 17 patients (11 men and six women; median age, 57 years; age range, 36 to 88 years) who underwent surgery for treatment of gastroesophageal reflux disease. All patients demonstrated unequivocal reflux, either at endoscopy or 24-hour pH testing. There was a significant increase in lower esophageal sphincter pressure after surgery, and no patient demonstrated abnormal reflux on pH testing. Gastric emptying of liquids and solids was not altered by surgery. Six months after surgery, all symptoms except dysphagia had significantly improved. Thirty-three months after surgery, six patients described symptoms as severe as or worse than those before surgery. Four patients had the prosthesis removed, two because of dysphagia alone, one because of reflux and dysphagia, and one because of flatulence and bloating. The patients who required removal of the prosthesis because of dysphagia had gross delay of esophageal emptying. We conclude that the Angelchik prosthesis is an effective antireflux device, but it interferes with esophageal function in some patients, requiring removal of the prosthesis. We think the rate of removal of the prosthesis is too high for its routine use in the treatment of gastroesophageal reflux disease.

Gastroesophageal reflux disease (GERD) contributes to the development of many otolaryngologic symptoms and conditions, including chronic throat clearing, cough, sore throat, contact ulcer and granuloma, globus pharyngeus, cervical dysphagia, cancer of the larynx, subglottic stenosis, and cricoarytenoid arthritis. These conditions are discussed and the pathogenesis of GERD is also detailed.

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.
