Cimetidine in the treatment of symptomatic gastroesophageal reflux: a double blind controlled trial.

The effectiveness of cimetidine for symptomatic relief in patients with chronic gastroesophageal reflux was studied in a multicenter, double blind clinical trial. Patients were entered into the study for a total of 8 weeks, receiving either cimetidine, 300 mg four times daily, or identical placebo tablets. Throughout the trial, frequent assessments were made of symptom severity and frequency, combined with careful measurement of antacid use. Esophagoscopy, esophageal acid sensitivity, and lower esophageal pressures were performed before and at the completion of the treatment period. Significant (P less than 0.05) decreases in symptom frequency and severity were noted throughout the study in the cimetidine-treated patients, as compared with the placebo group. This subjective improvement was corroborated by a concomitant decrease in antacid use, which was significantly (P less than 0.05) reduced in the cimetidine-treated group. In addition, significant improvement in esophageal acid sensitivity resulted from cimetidine therapy. No objective improvement in esophageal endoscopic appearance or sphincter pressures was noted. The results of this double blind trial indicate that cimetidine is more effective than the placebo for the relief of symptoms of gastroesophageal reflux.

Esophageal manometrics in patients with angina-like chest pain.

Fifty-eight patients with angina-like chest pain had esophageal manometric testing. Forty-three had no evidence of coronary artery disease at the time of referral or at subsequent contact; 15 patients were proven to have coronary artery disease. High-amplitude contraction waves were the most frequently found manometric abnormality (15 patients). Less frequent were increased duration of contractions, achalasia, and diffuse esophageal spasm; the latter was present in only 3 patients. An approach to the interpretation of information obtained during manometry is presented. Using this approach, the esophagus was strongly implicated as the cause of the pain in 20 patients and was suspect in 18 others. Seven patients had results that exonerated the esophagus, and in the 13 remaining individuals, the esophagus was probably not the offending organ.

Studies of idiopathic intestinal pseudoobstruction. II. Hereditary hollow visceral myopathy: family studies.

Twelve relatives of a 15-year-old girl with idiopathic intestinal pseudoobstruction were studied with esophageal manometry or cine-esophagography to determine whether the disease was genetically transmitted. Four maternal relatives, including the patient's mother, 13-year-old brother, one aunt, and one of that aunt's children had mild dysphagia and esophageal motor dysfunction. In addition, the patient's mother and 13-year-old brother had a flaccid bladder and bilateral ureteral reflux, respectively. The brother had abnormal bladder smooth muscle by light microscopy. We conclude that idiopathic intestinal pseudoobstruction in this family is secondary to a generalized disease of smooth muscle which is transmitted as a dominant trait of variable expressivity, manifested in some family members as a mild disorder of esophageal smooth muscle dysfunction, at times accompanied by bladder dysfunction. We suggest that this form of idiopathic intestinal pseudoobstruction be called "hereditary hollow visceral myopathy." Esophageal manometry may prove useful as a tool for studying the inheritance of this disorder.

Esophageal reflux--an unrecognized cause of recurrent obstructive bronchitis in children.

Forty-three children with recurrent obstructive bronchitis but without prominent gastrointestinal symptoms were studied for esophageal reflux roentgenographically and by manometry. Roentgenographic evidence for reflux was shown in 26; these patients had a mean lower esophageal sphincter pressure of 6.3 mm Hg as compared to a mean LES pressure of 21.9 mm Hg in normal control infants. The remaining 17 patients had a mean LES pressure of 10.0 mm Hg, also significantly lower than that of control subjects. Fifteen of 20 patients with recurrent obstructive bronchitis noted alleviation of their pulmonary symptoms after medical treatment of their reflux. Sequential studies of another group with radiologically demonstrated reflux showed increases in sphincter pressures and disappearance of radiologically observed reflux in one third of the patients. It is suggested that esophageal reflux should be sought in patients with recurrent bronchitis: if found, antireflux therapy might be expected to improve the pulmonary symptomatology.

Esophageal motor dysfunction in idiopathic intestinal pseudoobstruction.

Five patients with idiopathic intestinal pseudoobstruction were studied with esophageal manometry and all had abnormalities of esophageal motility. In 2, primary peristalsis was replaced by simultaneous contractions and repetitive spontaneous activity was marked. The lower esophageal sphincter failed to relax and the Mecholyl test was positive in both. In the other 3, primary peristalsis was absent, low amplitude simultaneous waves followed swallows, no spontaneous activity was present, and defects in lower esophageal sphincter relaxation were found in two. The Mecholyl test was negative in the one patient tested. The esophagus appears to be abnormal in idiopathic intestinal pseudoobstruction and could prove useful as an organ for diagnostic study in patients who may have this syndrome.

Surgical correction of reflux. An effective therapy for esophageal strictures.

An effective antireflux operation, posterior gastropexy with cardiac calibration, was performed on 24 patients with well established peptic strictures of the esophagus. Without intraoperative or postoperative dilation, the diameter of the strictures went from a mean of 6.3 mm to a postoperative mean diameter of 13.0 mm. Significant increases in sphincter pressure were recorded and endoscopic evaluation showed a return to normal. Preoperative dysphagia was relieved. It is concluded that an adequate antireflux operation will obviate the need for postoperative dilations or more formidable operations such as interposition.
