Barrett's esophagus is a common finding in patients with gastroesophageal reflux and is associated with a high incidence of serious complications (stricture, ulceration, and carcinoma). The reason that only a portion of patients with reflux develop Barrett's esophagus and why some are prone to develop complications is unknown. Twenty-three patients with Barrett's esophagus underwent endoscopy, 24-hour esophageal pH monitoring, and manometry. Nine of these patients with gastritis underwent 24-hour gastric pH monitoring, and three with symptoms of duodenogastric reflux underwent 99mTc-labeled hepato-iminodiacetic acid scanning. Patients with complicated (n = 12) and uncomplicated (n = 11) Barrett's esophagus were compared with each other and with patients with reflux esophagitis (n = 53) and normal volunteers (n = 50). Patients with Barrett's esophagus showed an increased exposure to acid and alkaline gastric juice compared with patients with esophagitis and normal volunteers. In the patients with Barrett's esophagus with and without complications, there was no significant difference in age, incidence of defective lower esophageal sphincter, incidence of defective peristalsis, extent of the Barrett's epithelium, or percent time the esophageal pH was less than 4. In contrast, the percent time the esophageal pH was greater than 7 was significantly greater in patients with complications. This alkaline exposure is likely to be related to duodenogastric reflux. This was supported by positive gastric pH scores for duodenogastric reflux and 99mTc-labeled hepato-iminodiacetic acid scans in patients with Barrett's complications. These findings suggest that the development of complications in Barrett's esophagus is the result of the damaging effect of refluxed duodenal juice.

Delayed gastric emptying in patients with gastroesophageal reflux disease may be due to an incompetent distal esophageal sphincter and/or a gastric abnormality. To determine the influence of the Nissen fundoplication on gastric emptying we studied the rate of gastric emptying before and after operation in 25 patients with proved gastroesophageal reflux disease. Nine patients had no gastric pathology, 9 had gastric acid hypersecretion, 5 had gastritis, and 2 had evidence of significant duodenogastric reflux. All were treated by Nissen fundoplication. Those with gastric acid hypersecretion also had a proximal gastric vagotomy (PGV) and the two patients with pathologic duodenogastric reflux were treated by a bile diversion procedure. We found that in gastroesophageal reflux disease with associated gastric pathology there was a higher prevalence of delayed gastric emptying before operation than in patients without gastric pathology. Nissen fundoplication was associated with speeding of gastric emptying in patients with or without gastric pathology. Proximal gastric vagotomy performed in association with Nissen fundoplication augmented the speeding of gastric emptying, which was advantagenous in most cases but detrimental in two. Every patient in whom gastric emptying was not normalized had postoperative symptoms. Only two of 20 patients with normal postoperative gastric emptying had postoperative symptoms. Both patients had preexisting gastric pathology. Based on these findings, the side effects associated with Nissen fundoplication are due to the failure to normalize gastric emptying rather than the operation.

Barrett's esophagus is a gastrointestinal metaplasia of the esophageal epithelium occurring frequently in adults with long-standing peptic esophagitis. Recent reports of Barrett's esophagus in children with gastroesophageal reflux (GER) showed that also at the pediatric age intestinal metaplasia of the esophagus may occur in association with peptic esophagitis. Recently a close association between Campylobacter-like organisms (CLOs) and gastritis has been found in the stomach of both adults and children with a variety of peptic diseases, but evidence of such infection in specimens of Barrett's epithelium has never been described in children. We report here a child with Barrett's esophagus and GER, treated with H2 blockers, who showed a Barrett's ulcer in association with CLO infection. The addition of amoxicillin to antireflux treatment was accompanied by healing of the ulcer, suggesting that bacterial infection of Barrett's epithelium may have an important role in determining its inflammation and possibly ulceration.

Paraesophageal hiatal herniation and pyloric obstruction were diagnosed in a pup with a history of vomiting. Findings of contrast radiography included esophageal reflux, delayed gastric emptying time, and paraesophageal herniation. Exploratory celiotomy revealed increased firmness of the pylorus and a primary defect in the esophageal hiatus, which allowed gastric herniation. Nissen fundoplication was performed following reconstruction of the esophageal hiatus, and pyloroplasty was performed to relieve the gastric outlet obstruction. Pyloric biopsy findings were consistent with a diagnosis of chronic gastritis. Recovery from surgery was initially unremarkable; however, the dog died suddenly 3 weeks after surgery. Necropsy revealed a large diaphragmatic hernia adjacent to the esophageal hiatus; the hernia had resulted in incarceration of the abdominal organs. The hiatal hernia reconstruction remained intact and was not the cause of the diaphragmatic disruption.

Dyspepsia, defined as chronic or recurrent upper abdominal pain or nausea, is a common occurrence. Dyspepsia without an ulcer (non-ulcer dyspepsia) is diagnosed in patients at least twice as often as peptic ulceration. Diseases that may present with similar symptoms include gastroesophageal reflux, biliary tract disease, chronic pancreatitis, and irritable bowel syndrome. A careful history and physical examination, supplemented by selected tests, usually lead to a correct diagnosis. The pathogenesis of non-ulcer dyspepsia remains unknown. Gastric acid secretion, duodenogastric reflux, psychological factors, environmental exposures, and heredity probably do not play a major role. Some patients may have motility disturbances, but whether these disturbances cause dyspepsia is unknown. Campylobacter pylori infection and associated gastritis are common in non-ulcer dyspepsia, but their etiologic role is controversial, as is the importance of chronic duodenitis. By recognizing the heterogeneity of patients who present with non-ulcer dyspepsia, more rational management may be possible. Although an empiric trial of antacids or H2 blockers has been recommended to treat dyspepsia, most controlled trials show that although these substances reduce severity of symptoms, they are no more effective than placebos in non-ulcer dyspepsia.

The aim of this study was to assess the incidence of oesophageal abnormalities and to determine their nature in patients with retrosternal chest pain and normal coronary angiography with a negative coronary spasm provocation test. Oesophageal manometry was carried out in all cases with or without a spasm provocation (usually alkalosis) test. Forty consecutive patients were studied: 19 men (47.7 +/- 10.0 years) and 21 women (54.7 +/- 7.5 years). A history of gastro-intestinal disorder was obtained in 57 p. 100 of cases (hiatal hernia and/or gastro-oesophageal reflux, biliary lithiasis and/or cholecystectomy, gastritis). Seventeen patients had broad based powerful oesophageal contractions which are an established cause of pain; they were recorded under basal conditions in 5 cases and after a provocation test in 12 cases. Two patients had a megaoesophagus without giant waves. Thirteen patients had manometric signs of reflux (malposition and hypotonia of the lower oesophageal sphincter) of whom 7 had giant waves on provocation. In addition, three patients experienced pain during gastro-oesophageal reflux (1 case) or hypotonia of the lower oesophageal sphincter (2 cases). In all, a very probable oesophageal origin of the chest pain was demonstrated in 22 patients (55 p. 100 of cases).

Gastritis has a wide spectre of definition modalities. Most previous studies have compared symptomatology with histologic gastritis with negative results. We believe that this may be due to inadequate definition criteria and emphasize this point by comparing gastroesophageal reflux with duodenogastric reflux. A prospective randomized trial has been conducted for half a year comparing Sucralfate with a placebo in patients with symptomatological and macroscopical gastritis. Although approximately one hundred patients met the endoscopic criteria, the vast majority could not be included due to well-defined interfering diseases, and thus the material is still too sparse to give any indication of the influence of Sucralfate on endoscopic gastritis, although the preliminary overall results seem promising.

Among 857 patients admitted from October 1977 to December 1984 with acute upper gastrointestinal hemorrhage, 165 (19.5%) had endoscopically proved esophageal or gastric varices. Among this group, varices were considered as the actual bleeding lesion in only 83 (9.7%). Stigmata of variceal bleeding were observed in 76 (92%) including 35 venous spurts, 12 venous oozes, 20 adherent clots, and 14 "platelet aggregates." In only seven cases, variceal rupture could only be presumed, because no other lesion was present. In the other 82 patients, a lesion other than varices was the bleeding source, mostly peptic ulcers (32 = 38%) and erosive gastritis (30 = 36%). One-third of the patients with bleeding varices required more than one endoscopy to provide evidence of variceal bleeding. The most frequent bleeding point was the cardia and a good correlation between variceal size and bleeding was observed. There was no relationship with evidence of gastroesophageal reflux.

Fine transverse folds of the esophagus are well described as a transient motor phenomenon seen in patients with or without gastroesophageal reflux. They appear to be due to contraction of the muscularis mucosa and are thought to have little, if any, significance. We have observed similar transverse folds in the gastric antrum during double-contrast upper gastrointestinal series in five patients. In contrast to the transient nature of the folds in the esophagus, these gastric folds were more persistent. They were seen in multiple spot images with the gastric antrum distended or partially collapsed and even during peristalsis. In follow-up studies, the folds were repeatedly demonstrated in two patients. Two patients had associated gastric polyps with histologic evidence of chronic gastritis; however, the antral mucosa appeared normal on endoscopy. The remaining three patients had no associated gastric disease. The pathophysiologic significance of these folds is yet to be determined; however, they appear to be clinically insignificant.

Non-ulcer dyspepsia (NUD) is defined as dyspepsia in which investigation shows no evidence of focal gastroduodenal disease or oesophagitis. The aim of the present study was to determine the proportion of NUD patients with other identifiable diseases. We interviewed 327 consecutive patients who had at least 1 month of dyspepsia before a panendoscopy that showed no evidence of oesophagitis, malignancy, or peptic ulcer. Symptoms were assessed by a structured history questionnaire. The existence of gallstones was excluded radiologically. Of the subjects studied, 75 (23%) had irritable bowel syndrome and 71 (22%) gastro-oesophageal reflux, whereas 63 (19%) had both, 25 (8%) had aerophagy, and 14 (4%) had gallstones. Of the remaining 79 patients (24%) 6 had duodenitis and 10 gastritis, whereas 1 had both. Sixty-two subjects (19%) had entirely normal endoscopic results and no ascertainable cause of their dyspepsia (termed provisionally essential dyspepsia). It is concluded that, whereas three-quarters of NUD patients have diseases that fall into other diagnostic categories, nearly one-quarter have essential dyspepsia.
