An evaluation was done of 325 consecutive patients who underwent esophageal manometry to investigate the relationship between solid food dysphagia and peristaltic dysfunction in gastroesophageal reflux disease. All patients with dysphagia were endoscoped to evaluate for mechanical obstruction. Manometry was done focusing on the incidence of peristaltic dysfunction (failed peristaltic sequences or sequences characterized by foci of hypotensive peristalsis). The major finding was that the severity of manometrically demonstrated peristaltic dysfunction in reflux patients correlated with the prevalence of dysphagia. After excluding patients with esophageal rings or strictures from the analysis, the overall prevalence of dysphagia was 39% among the 157 reflux patients. Within this group, 29% of patients with minimal peristaltic dysfunction experienced dysphagia compared to 78% of patients with severe peristaltic dysfunction. We conclude that peristaltic dysfunction should be considered along with mechanical obstruction as a potential cause of dysphagia in patients with gastroesophageal reflux disease.

Fifty-eight patients had surgery for carcinoma of the esophagus at Scripps Clinic, La Jolla, Calif, from 1976 to 1986. Esophagectomy with reconstruction by colon interposition was done in 24 patients with adenocarcinoma arising in columnar-lined epithelium (Barrett's). In 5 patients, obstructive symptoms had not yet developed and the diagnosis was made by endoscopy performed for evaluation of gastroesophageal reflux. Dysphagia had just started in 12 additional patients and no weight loss had been noted. The operation was palliative in 14 patients and potentially curative in the other 10. Only 3 patients had negative lymph nodes. Ten patients were alive after 2 to 11 years. Encouraging results were indicated for surgical treatment of adenocarcinoma of the esophagus developing in Barrett's epithelium. A good outcome can be obtained with resection even in patients with lymph node metastases.

Gastro-oesophageal reflux occurs when the pressure barrier of the lower oesophageal sphincter (LOS) fails due to a low basal pressure (less than or equal to 6 mm Hg), sphincteric relaxations or a noncompensated increase in intragastric pressure. This reflux becomes pathological when it leads to symptoms severe enough for the patient to seek medical help or results in reflux oesophagitis or its complications. Damage to the oesophageal mucosa develops when the balance between aggressive and defensive factors is no longer in equilibrium. The main aggressive factor is acid-pepsin or alkaline bile secretion. Defence against this aggression is based on rapid removal of the refluxate from the oesophagus (oesophageal clearance) and on poorly understood mucosal resistance. The length of time acid is in contact with the oesophageal mucosa is shortened by adoption of an upright position, by swallow-induced oesophageal peristalsis and saliva. Treatment of pathological reflux aims (1) to decrease acid aggression by means of H2-receptor antagonists or proton pump inhibitors; (2) to strengthen the anti-reflux barrier and improve oesophageal clearance by prokinetic drugs that increase the LOS pressure and enhance peristaltic contractions; and (3) to boost mucosal resistance by sucralfate or prostaglandin analogues. Initial treatment of gastro-oesophageal reflux disease may be symptomatic provided that there are no alarming symptoms, such as dysphagia, anaemia or weight loss. Usually either H2-receptor blockers or prokinetic drugs are used. Endoscopy is indicated whenever alarming symptoms are present and when there is insufficient symptomatic improvement after a 4-6-week therapeutic trial. Moderate oesophagitis may be treated in the same way.(ABSTRACT TRUNCATED AT 250 WORDS)

Schatzki's ring is a distinct anatomical entity associated with hiatal hernia; however, its significance is unclear. Thirty-two patients with a radiologically demonstrated Schatzki's ring were compared with 32 patients with hiatal hernia and no Schatzki's ring. Schatzki's ring was confirmed on endoscopy in 59 percent of patients. Seventy-five percent of patients with Schatzki's ring presented with dysphagia compared with 41 percent of control patients (p less than 0.01). Heartburn and regurgitation were less frequent than in control subjects (38 percent versus 91 percent, p less than 0.0001). Schatzki's ring patients were found to have a lower incidence of proven gastroesophageal reflux on 24-hour pH monitoring. Those with proven reflux were found to have a more efficient lower esophageal sphincter than control patients. Sixty-two percent of Schatzki's ring patients without proven reflux had a history of chronic ingestion of drugs known to be damaging to the esophageal mucosa, whereas only 26 percent of patients with reflux had this history. This was found in 16 percent of controls. Sixty-two percent of Schatzki's ring patients without reflux responded to a single dilatation compared with 37 percent of those with reflux. These findings suggest an etiologic relationship between pill lodgement and Schatzki's ring in patients without reflux and indicate that different therapy should be employed in these patients.

Between 1976-1987, 408 patients were studied for Reflux Esophagitis. Clinical, endoscopic, manometric characteristic were analyzed, and scintigraphic studies for gastroesophageal and duodenogastric reflux were done. Esophagitis was classified according endoscopic findings in Esophagitis grade I (non confluent erosion), grade II (confluent erosions), grade III ("uncomplicated Barrett syndrome") and grade IV (esophageal ulcer or stricture ("complicated Barrett syndrome"). Fifty six (56) patients with mild (grade I), 52 with moderate (grade II) and 146 patients with severe esophagitis (56 grade III, and 90 grade IV) were included in this protocol. No significative differences were found in clinical feature except dysphagia and bleeding, symptoms more frequent in severe esophagitis than mild or moderate grades. Lower esophageal sphincter pressure was similar in both groups of patients, but the frequency of motor disorders was significative higher in severe esophagitis. Scintigraphic gastroesophageal reflux was positive in all patients and no differences in gastric emptying and duodenogastric reflux were detected. In conclusion, the differences in subjective and objective analysis between different grade of esophagitis suggest to employ different models of management.

A total of 61 patients with gastro-oesophageal reflux; resistant to medical therapy, were entered into a prospective randomized trial comparing the Angelchik antireflux prosthesis with Nissen's fundoplication. Both groups had a similar age and sex distribution and their reflux profiles were comparable. An Angelchik prosthesis was inserted in 30 patients and 31 underwent fundoplication. The mean duration of postoperative follow-up was 38 months. At clinical assessment 23 (77 per cent) of the Angelchik group were graded Visick grade I or II, compared with 29 (94 per cent) of the Nissen group. Assessment by 24 h pH monitoring and manometry between 3 and 6 months after operation showed that both procedures were equally effective in reducing reflux and increasing lower oesophageal sphincter pressure. However, long-term endoscopic follow-up revealed grade III oesophagitis in seven patients in the Angelchik group. No patient in the fundoplication group had grade III oesophagitis. Three of eight patients with strictures in the Angelchik group reported persistent dysphagia. All seven patients with strictures in the Nissen group were relieved of their dysphagia. Migration or erosion of the prosthesis did not occur. Three prostheses (10 per cent) were removed, two for dysphagia and one because of sepsis.

The authors report their experience of the surgical treatment of gastroesophageal reflux using a circular cardiopexy with the ligamentum teres (Rampal-Marchal's procedure) associated with a 180 degrees posterior fundoplication. 100 patients with severe reflux (76% oesophagitis) were operated on with this procedure over a 6 year period. Symptoms of reflux disappeared immediately in 99% cases, which corresponded to the healing of oesophagitis with 45 out of the 46 patients controlled with endoscopy, and to a significant increase of inferior sphincteric pressure (from 12 cm H20 to 24 cm H20). Objective controls by post prandial pHmetry evidenced persistent reflux with 4 patients, but 3 of them are totally free of symptoms. Operative mortality was 2%. Transient dysphagia was observed in 25% cases. 96 patients were reviewed with a mean follow up of 23 months. 3 clinical recurrence of reflux were observed (4%) but no oesophagitis was found on endoscopic controls with these 3 patients and none had to be reoperated on. Actuarial chance to remain free of recurrence was estimated at 96.6% up to 48 months according to the Kaplan-Maier's method. Cardiopexy with the ligamentum teres ensures the lengthening of the abdominal portion of the esophagus and anchors the antireflux assembly within the positive pressure environment of the abdomen in a strong and flexible way. It seems to be an advisable procedure for the treatment of GE reflux.

Symptomatic gastroesophageal reflux is one of the most common complaints encountered by clinicians. The pathogenesis of reflux remains unclear, but multiple factors are involved. Heartburn is the most common clinical manifestation. The history and barium esophagram provide sufficient diagnostic information in most cases. Other studies, including ambulatory pH monitoring, the Bernstein test, endoscopy with biopsy, and esophageal manometry, are warranted if the patient has atypical symptoms, an incomplete response to therapy, dysphagia, or abnormalities on the esophagram. Proper utilization of these studies requires an understanding of the questions each test answers. Reflux disease is often a chronic problem. Many patients can be treated symptomatically by a combination of life-style modifications and use of antacids. Patients who do not respond adequately to these simple measures or who have documented erosive esophagitis usually require further drug therapy.

The diagnosis of GERD requires the thoughtful evaluation of a patient's symptoms and clinical course. In young patients with classical reflux symptoms in the absence of untoward complications such as structure, bleeding or pulmonary aspiration, antireflux treatment can be instituted without the need for diagnostic testing. A large number of patients will demonstrate a good clinical response to medical therapy. The diagnostic challenge arises when symptoms of reflux masquerade as cardiac and pulmonary disease or do not respond to simple medical treatment. The use of diagnostic testing to determine the presence and quantity of reflux is helpful in establishing the diagnosis in atypical settings. Prolonged pH monitoring offers the opportunity to monitor symptoms in a physiologic setting over a prolonged period and to provide a correlation of symptoms with the presence of reflux. Endoscopic evaluation is most important in evaluating patients with complications such as peptic strictures, hemorrhagic esophagitis, or Barrett's metaplasia. In these situations, important diagnostic and prognostic information as well as therapeutic intervention can be gained through endoscopy. In patients with peptic strictures, palliation can be achieved by endoscopic dilatation. The number of options available for the medical management of reflux disease has increased significantly in recent years. The introduction of effective agents to block acid secretion has provided a significant advance in the medical treatment of gastroesophageal reflux. Prokinetic agents offer an attractive alternative either alone or in combination with acid inhibition. Early results using parietal cell proton-pump blocking agents suggest that they may be effective in the treatment of severe esophagitis previously resistant to medical therapy. Despite significant advances in the medical treatment of GERD, a number of patients (5 to 10 per cent) may require antireflux surgery. The Nissen fundoplication has been shown to be an effective means of attaining mucosal healing usually accompanied by symptomatic relief. The use of a "loose wrap" performed over a large bore dilator avoids the postoperative problems of dysphagia or gas bloat. Despite improvements in our diagnostic and therapeutic armamentarium, a number of patients continue to pose a challenge for the clinician. There remains a clear need for more well-designed, well-controlled studies to assist in the effective treatment of this ubiquitous and often debilitating disease.

Thirty-one patients about to undergo surgery for gastroesophageal reflux were randomized into either a Nissen fundoplication group (12) or a modified Toupet semifundoplication group (19). All patients were followed on a long-term basis for 5 years with a standard questionnaire, endoscopy, and manometry. Ninety-five percent of the patients in the modified Toupet group had good or excellent results versus 67% for the Nissen group. However both procedures are effective in curtailing esophagitis with an improvement of the endoscopic grading in the Nissen group by 91% and 89% in the group undergoing the modified Toupet procedure. A significant improvement in symptoms (acid regurgitation, heartburn, retrosternal pain) was noted in both groups, except for dysphagia in the Nissen group. Three patients with a Nissen fundoplication had a slipped Nissen requiring reoperation and two had gas-bloat syndrome. These specific complications of the Nissen procedure were not found in the modified Toupet group.
