Lung transplantation is one of the highest risk solid organ transplant modalities. Recent studies have demonstrated a relationship between gastroesophageal reflux disease (GERD) and lung transplant outcomes, including acute and chronic rejection. The aim of this review is to discuss the pathophysiology, evaluation, and management of GERD in lung transplantation, as informed by the most recent p...

Up to 50% of patients with gastroesophageal reflux disease (GERD) still suffer from GERD symptoms despite proton pump inhibitor (PPI) therapy, indicating a need for new treatments. The lower esophageal sphincter (LES) plays a crucial role in maintaining the mechanical barrier necessary for prevention of gastric reflux. Transient LES relaxation (TLESR) is an important factor behind the occurrenc...

We have evaluated esophageal tone in two different conditions that, in some cases, similarly impair phasic esophageal motility. Studies were performed in 14 healthy volunteers, 10 patients with total esophageal aperistalsis secondary to gastroesophageal reflux disease (GERD), and 25 untreated achalasia patients. We quantified esophageal compliance and relaxation induced by a nitric oxide donor ...

The incidence of gastroesophageal reflux disease (GERD) is increasing and if left untreated can lead to significant patient morbidity and even death. The disease results from the abnormal reflux of gastric contents into the distal esophagus causing symptoms in most and subsequent mucosal damage in some. Several investigations can be used to confirm the diagnosis, but most are dependent on the p...

Helicobacter pylori organisms that infect the stomach conceivably could contribute to esophageal inflammation in patients with gastroesophageal reflux disease (GERD) through any of at least three potential mechanisms: 1) by causing an increase in gastric acid secretion; 2) by spreading to infect the gastric-type columnar epithelium that occasionally can line the distal esophagus; and/or 3) by s...

BACKGROUND & AIMS Gastroesophageal reflux causes inflammation and intestinal metaplasia and its downstream sequelum adenocarcinoma in the distal esophagus. The incidence of esophageal adenocarcinoma has increased approximately 6-fold in the United States since the 1970s, accompanied with a significant increase in the prevalence of gastroesophageal reflux disease (GERD). Despite extensive epidem...

Chagas disease (CD) is very prevalent in South America, with wellknown manifestations in the digestive system. CD esophagopathy leads to a clinical and manometric picture similar to idiopathic (primary) achalasia. Although the treatment for CD esophagopathy is well established, South American surgeons and gastroenterologists are sometimes faced with CD patients without esophageal involvement bu...

Gastroesophageal reflux disease (GERD) is clearly explained as the unintentional passage of stomach contents through the esophagus that takes place many times during the day both in children and in adults. GERD leads to symptoms of heartburn and regurgitation, these defined esophageal symptoms are in dichotomy with extraesophageal symptoms of GERD. These extra-esophageal symptoms include severa...

BACKGROUND Proton pump inhibitors (PPI) are the drugs of choice for treatment of gastroesophageal reflux disease (GERD). Omeprazole, the first PPI commercialized, is now available in different formulations. OBJECTIVES To compare the efficacy of different omeprazole formulations on gastric acid secretion measured by intragastric and esophageal pH monitoring in patients with reflux esophagitis....

BACKGROUND A Stanford University study reported that in asymptomatic GERD patients who were being treated with a proton pump inhibitor (PPI), 50% had pathologic esophageal acid exposure. AIM We considered the possibility that the high prevalence of pathologic esophageal reflux might simply have resulted from calculating acidity as time pH < 4. METHODS We calculated integrated acidity and ti...
