Sucralfate used as adjunctive therapy in patients with severe erosive peptic esophagitis resulting from gastroesophageal reflux.

A total of 36 patients with grade 2 or greater erosive esophagitis and an abnormal 24-h pH monitor study, were treated in a randomized, double-blind fashion to assess the efficacy of sucralfate suspension as adjunctive therapy to cimetidine for severe esophagitis secondary to gastroesophageal reflux. Treatment consisted of cimetidine, 300 mg qid and either sucralfate suspension (1 g/10 ml) or an identical placebo suspension, 10 ml after meals and 20 ml hs. Patients were treated for 12 wk unless endoscopic healing occurred earlier. Initial evaluation and monthly follow-up consisted of symptom monitoring, endoscopic evaluation and pre- and post-therapy esophageal manometry, Bernstein test, and 24-h pH monitoring. The combination of cimetidine and sucralfate suspension was superior to cimetidine alone in improving daytime heartburn symptoms (p less than 0.05) but not nighttime heartburn, dysphagia, or regurgitation. Sucralfate plus cimetidine improved the overall endoscopic outcome of esophagitis more than cimetidine alone (p less than 0.05). More patients exhibited endoscopic healing in the adjunctive sucralfate group than in the cimetidine-only group. Endoscopic healing, however, was not statistically different between groups. We conclude that sucralfate used as adjunctive therapy to cimetidine resulted in improvement of some of the symptoms of reflux, and probably increases the likelihood of complete healing of esophagitis, compared with cimetidine alone.

Cycling, a manometric phenomenon due to repetitive episodes of gastroesophageal reflux and clearance.

We studied intraesophageal pressure changes in patients with symptoms of gastroesophageal reflux and an abnormal 24-hr pH monitoring record (N = 52). Our method was simultaneous esophageal manometry and pH monitoring. We observed a three-component esophageal manometric sequence (EMS). When this sequence recurred over and over, we termed this phenomenon "cycling." We found cycling in 35% of the patients (18/52). Those with cycling had lower basal LES pressures, more acid exposure, and an increased incidence of endoscopic esophagitis. That cycling resulted from repeated reflux events and their esophageal clearance was documented by scintigraphy during simultaneous manometry and pH monitoring (N = 7 patients). Cycling was found on the routine esophageal manometry record of 25% of symptomatic patients (N = 112) with an abnormal 24-hr pH score. In conclusion, cycling represents an esophageal manometric phenomenon due to repetitive reflux events. Its recognition during esophageal manometry may denote a severe reflux diathesis.

Gastric emptying of solid food in patients with gastroesophageal reflux.

While delayed gastric emptying of solid food has been reported in patients with symptoms of gastroesophageal reflux, the study populations were not defined by 24-h intraesophageal pH monitoring. Moreover, the influence that the gastric emptying rate may have on patterns of reflux during the day or night, as well as on esophagitis, is not known. In this study, we compared the gastric emptying rate of solid food (in vivo intracellular labeled chicken liver) observed in asymptomatic control volunteers (n = 15) with that of symptomatic patients with an abnormal 24-h pH record who had either the presence (n = 22) or absence (n = 11) of endoscopic esophagitis. We found no significant difference in the gastric emptying rate between the asymptomatic control volunteers and the symptomatic patients with and without esophagitis. Moreover, there was no significant correlation between the gastric emptying rate and the degree of daytime or nighttime distal esophageal acid exposure found during 24-h intraesophageal pH monitoring. Only 6% of the symptomatic patients had a gastric emptying rate that exceeded the mean value plus 2 SD of that found in the asymptomatic control volunteers. We believe these support a de-emphasis of the role that delayed gastric emptying of solid food may play in the pathophysiology of gastroesophageal reflux in most patients.

Rumination, heartburn, and daytime gastroesophageal reflux. A case study with mechanisms defined and successfully treated with biofeedback therapy.

A 31-year-old man with a 19-year history of rumination developed frequent episodes of heartburn and regurgitation associated with acid gastroesophageal reflux that occurred predominantly during the day. This reflux and its attendant symptoms resulted from abdominal muscle contractions at the time of gastroesophageal pressure equilibration (i.e., common cavity phenomena) consistent with the egress of air from the stomach to the esophagus. A voluntary pharyngeal maneuver unassociated with swallowing but simultaneous with the abdominal contraction resulted in a decrease in upper esophageal sphincter pressure. This lowered pressure facilitated acid esophagopharyngeal regurgitation at a velocity of 100 cm/s. Biofeedback therapy directed at relaxing the abdominal muscles during eating and avoiding the pharyngeal maneuver resulted in a decrease in reflux and marked improvement in symptoms.

Adult duodenal web associated with reflux esophagitis.

Duodenal webs are the third leading cause of alimentary tract obstruction in infants. They rarely present in adulthood, with 47 cases reported in the literature. These seems to be an association with peptic ulcer disease. They most frequently occur in the vicinity of the ampulla of Vater. A case of adult duodenal web associated with peptic ulcer disease and reflux esophagitis is reported. This appears to be the second reported case associated with significant reflux esophagitis. Etiology, presentation, diagnosis, and management are discussed.

Hiccups associated with reflux esophagitis.

A 67-yr-old man with protracted hiccups, as well as reflux esophagitis and a stricture, was found to have heartburn and water brash only during episodes of hiccups. Intraesophageal pH monitoring showed acid gastroesophageal reflux increased during these episodes and decreased with cessation of hiccups. After all attempts failed to relieve his hiccups, a Nissen fundoplication relieved heartburn, healed the esophagitis, and stopped excessive reflux of acid gastric juice, even though the hiccups persisted. These observations showed that reflux provoked by prolonged hiccups could either have adversely affected preexistent reflux esophagitis and stricture or conceivably could have caused these complications.

Esophageal hematoma. Four new cases, a review, and proposed etiology.

We report four cases of esophageal hematoma and emphasize that endoscopically and radiographically it may simulate a neoplasm. After a review of 26 cases, we found that patients with normal hemostasis often had esophageal hematoma occur distally after vomiting. Most of these hematomas probably originated from a Mallory-Weiss laceration. In contrast, patients with impaired hemostasis had esophageal hematoma occur proximally or at multiple sites. Many of these hematomas occurred spontaneously, without a history of vomiting, and probably resulted from impaired coagulation. Regardless of etiology most esophageal hematomas were associated with a benign course.
