A prospective multifactorial study of symptoms and disturbance of gastrointestinal function has been undertaken in 50 patients with non-ulcer dyspepsia. Objective tests including solid meal gastric emptying studies, gastric acid secretion, E-HIDA scintiscan for enterogastric bile reflux, and hydrogen breath studies were carried out in all patients and validated against control data. Gastroscopy and biopsy were carried out in non-ulcer dyspepsia patients only. Non-ulcer dyspepsia patients were categorised on the basis of predominant symptoms as: dysmotility-like dyspepsia (n = 22); essential dyspepsia (n = 14), gastro-oesophageal reflux-like dyspepsia (n = 11); and ulcer-like dyspepsia (n = 3). In the total non-ulcer dyspepsia population, solid meal gastric emptying was delayed (T50 mean (SEM) = 102 (6) minutes (patients) v 64 (6) minutes (controls), (p less than 0.01) and high incidences of gastritis (n = 26) and Helicobacter pyloridis infection (n = 18) were found. An inverse correlation was observed between solid meal gastric emptying and fasting peak acid output (r = -0.4; p less than 0.01). Indeed gastric emptying was particularly prolonged in eight patients (T50 mean (SEM) = 139 (15) minutes) with hypochlorhydria. In the non-ulcer dyspepsia population oral to caecal transit time of a solid meal was delayed (mean SEM = 302 (14) minutes (patients) v 244 (12) minutes (controls) (p less than 0.01]. Seven patients had a dual peak of breath hydrogen suggestive of small bowel bacterial overgrowth. No association was observed between symptoms and any of the objective abnormalities. This multifactorial study has shown that hypomotility, including gastroparesis and delayed small bowel transit, is common in non-ulcer dyspepsia and may be related to other disorders of gastrointestinal function. No relation between symptoms and disorders of function, however, has been shown.

Non-ulcer like dyspepsia comprises different symptoms of the upper intestinal tract with no macroscopic lesion and no identifiable etiology. Motility disturbances are the best known alterations and resemble a delay in the emptying of the stomach. Gastroesophageal reflux may produce atypical symptoms. Mucosal lesions are sometimes found which may explain the transmucosal electric potential differences. However, chronic active Helicobacter associated gastritis is usually asymptomatic. There has been no proof of psychological factors up to now. In 50% of the patients the minimum pain threshold in response to distention of the stomach is lowered. No generally accepted therapy has been found. The therapeutic principles depend on the pathogenesis of the syndrome in every individual. Medication which may enhance as well as inhibit motility may be of help.

Fifty symptomatic patients with GERD, 20 each of non ulcer dyspepsia (NUD) & duodenal ulcer (DU) and 10 healthy controls were subjected to various tests employed for diagnosis of GERD. Among these endoscopy and histology had highest sensitivities (92% & 91% respectively) followed by Bernstein's test (overall 88%; early positivity 72%) and oesophagography (70%). The specificities of various tests were: endoscopy (86%), histology (82%) and Bernstein's test (overall 80%; early positive 94%). The false positivity was mainly in DU subjects where majority (greater than 84%) had two or more of these tests offitive. Any two of the three tests (endoscopy, histology & Bernstein's test) in combination had a sensitivity of 80-91% and a specificity of 90-92%. Our observations suggest that these tests, particularly in combination, are useful in establishing the diagnosis of GERD and that subclinical oesophagitis in DU might be responsible for the false positivity of these tests.

We reviewed the indications for and results of 788 consecutive upper gastrointestinal radiographs (UGIs) performed for ambulatory patients. Sixty-three percent of tests were ordered for the evaluation of abdominal pain, dyspepsia, or esophageal reflux. Of these tests, only 4.8% yielded results of major clinical importance to patient management. The yield for patients greater than 50 years of age was greater than for patients less than 50, 6.9 versus 3.0% (p = 0.04). There was a significant increase in yield with increasing age (chi trend = 11.6, p less than 0.001). Among patients with an indication of esophageal reflux alone (n = 62), there were no patients younger than age 60 with a test result that would significantly affect therapy or outcome. Among patients evaluated for fecal occult blood or weight loss (n = 120), 11.7% of tests ordered showed a finding of major clinical importance. In this group, the yield was higher in those greater than or equal to 50 years of age than in those less than 50, 14.7 versus 6.7%, (p = 0.2). These results indicate that UGIs ordered to evaluate pain or symptoms of esophageal reflux in the absence of bleeding or weight loss rarely yield results that significantly influence therapy. Such patients may be best served by an initial trial of empiric therapy or some other test. The UGI has greatest value when indications for it include bleeding or weight loss.

A method for outpatient 24-hr simultaneous recording of pH in the distal esophagus, fundus, and antrum was developed in order to detect acid, alkaline, alkalacid gastroesophageal reflux, and duodenogastric reflux and to study these phenomena in patients complaining of gastroesophageal reflux and dyspepsia related symptoms. Two hundred ninety-four studies were performed in 42 healthy volunteers and 237 patients. Three-probe ambulatory 24-hr esophagogastric pH monitoring applicability, tolerability, and capability to determine a relationship between symptoms which occurred during the tests, gastroesophageal reflux, and duodenogastric reflux episodes were assessed. Eighty-nine percent of the three-probe esophagogastric pH studies were easily performed. The examination was tolerated well by 86.1% of the patients and poorly by 13.9%. A temporal correlation between symptoms and pH activities was recognized in 61.3% when the esophageal tracing was considered (acid gastroesophageal reflux recording) and in 95.6% when the three pH traces were simultaneously interpreted. Alkalacid gastroesophageal reflux and duodenogastric reflux total percentage times were significantly higher in patients complaining of dyspeptic symptoms than in patients only affected by typical gastroesophageal symptoms. Three-probe 24-hr ambulatory esophagogastric pH monitoring is a simple, well-tolerated test that should be routinely adopted for the study of patients complaining of unclear upper gastrointestinal tract symptomatology.

Gastric motor dysfunction and concomitant gastric stasis have been implicated in the pathogenesis of nonulcer dyspepsia, but a cause-and-effect relationship is not established. Essential dyspepsia refers to a subgroup of nonulcer dyspepsia patients who have no evidence of irritable bowel syndrome, gastroesophageal reflux, or pancreaticobiliary disease. In 32 patients with essential dyspepsia, and 32 randomly selected dyspepsia-free community controls of similar age and sex, we measured gastric emptying of solids using Tc99m-Sulphur Colloid in a fried egg sandwich. Subjects with neuromuscular or other diseases that may alter gastric emptying were excluded. Symptoms were assessed by a standard questionnaire. Data processing was carried out "blinded" to the subjects' clinical status. Female patients took significantly longer to empty half the initial stomach activity (mean 90 min) than female controls (mean, 73 min; p = 0.02). The rate of emptying at 25 min was also significantly less in female patients than in controls. Female and male controls, and male patients, had similar emptying times. Delayed emptying was not associated with the occurrence of postprandial pain, belching, or nausea; there was a trend for the half-time rate of emptying to be greater in patients with abdominal distention. While gastric emptying of solids is slightly delayed in females with essential dyspepsia as a group, this may not explain their symptoms.

From August 1987 through July 1988, we evaluated antral biopsy specimens for Campylobacter pylori (CP) in 212 patients undergoing upper endoscopy. For those patients who had multiple endoscopies, the first endoscopy in which a urease test, histology, and culture were done was used to determine CP status. A patient was regarded as CP-positive if the culture was positive or if both a urease test and the histology were positive. Blacks had an increased CP positivity (61.2%) compared to whites (31.5%). Among non-ulcer patients, CP positivity was 52% in black patients and 18% in white patients. Age and gender were unrelated to CP positivity among controls and those without ulcers. There was increased CP positivity in patients with duodenal ulcers (85%), compared with those without ulcers (37%), and a trend toward increased positivity in those with gastric ulcer (53%) and duodenitis (50%). There was no increased CP positivity in patients with gastroesophageal reflux disease (28%), gastritis (29%), non-ulcer dyspepsia (43%), or the control patients with no gastroduodenal mucosal abnormalities (40%). CP-negative DU patients were older (average 71 yr) than CP-positive DU patients (43 yr), and female DU patients had a lower CP positivity (71%) than males (94%).

This open trial was conducted in 50 pregnant women, presenting during the 2nd and 3rd trimesters of their pregnancy typical symptoms of gastro-esophageal reflux (pyrosis, regurgitations, retro-sternal burning sensations, dyspepsia, epigastric burning). The treatment with Gaviscon, suspension to drink, lasted 1 month at a dose of 2 tablespoons, 4 times/day after meals and in the evening at bedtime. After one month, all symptoms were improved, in a statistically significant fashion, regarding their frequency, intensity and duration. The efficacy is considered positive in 98 p. cent of the cases; the patient's impression is favorable in 70 p. cent of the cases. Tolerance is excellent and the medication is satisfactorily accepted.

Gastrooesophageal reflux during liquid and solid meals was investigated in 43 patients with upper abdominal dyspepsia. Gastrooesophageal reflux occurred in 45% of the patients after a solid meal and in 90% after a liquid meal. Differences in oesophageal motility during liquid and solid meals are discussed as a possible explanation of the phenomenon.
