Objective: The Society of Abdominal Radiology established a panel to prepare a consensus statement on the role of barium esophagography in gastroesophageal reflux disease (GERD), as well as recommended techniques for performing the fluoroscopic examination and the gamut of findings associated with this condition., Conclusion: Because it is an inexpensive, noninvasive, and widely available study that requires no sedation, barium esophagography may be performed as the initial test for GERD or in conjunction with other tests such as endoscopy.

Chronic cough is common and has a significant impact on the wellbeing of patients and the use and cost of health care services. Traditionally the approach to chronic cough in patients who are nonsmokers and are not taking an angiotensin-converting enzyme inhibitor has focused on the diagnosis and management of the upper airway cough syndrome, asthma, and reflux disease. The evaluation of patients with chronic cough frequently involves trials of empiric therapy for these 3 conditions. Chronic cough may be perpetuated by abnormalities of the cough reflex and sensitization of its afferent and central components., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Objectives: The etiology of uninvestigated reflux is largely unknown. Although diet has been associated with uninvestigated reflux, the role of dietary patterns is not clear yet. The aim of this study was to investigate dietary patterns in relation to uninvestigated reflux among Iranian adults., Methods: This cross-sectional study was carried out within the framework of SEPAHAN (Study on the Epidemiology of Psychological, Alimentary Health and Nutrition) among Iranian adults. Dietary data were collected using a self-administered, 106-item, dish-based, semiquantitative food frequency questionnaire. Uninvestigated reflux was considered to be present when an individual reported to be suffering from heartburn sometimes or frequently in the preceding 3 mo. Specific dietary patterns were identified using factor analysis., Results: Complete information from 3846 individuals was available for statistical analysis. We identified four major dietary patterns: fast food, traditional, vegetarian, and Western. After controlling for potential confounders, no overall significant associations were found between these dietary patterns and uninvestigated reflux. However, participants in the third quintile of the traditional dietary pattern had greater odds of uninvestigated reflux, either in the crude (odds ratio [OR], 1.37; 95% confidence interval [CI], 1.09-1.74) or the adjusted (OR, 1.52; 95% CI, 1.16-2.00) model taking into account different confounders. After controlling for age, men in the second (OR, 1.64; 95% CI, 1.10-2.45) and women in the fourth (OR, 1.47; 95% CI, 1.02-2.11) quintiles of the fast food dietary pattern were more likely to have uninvestigated reflux. Moreover, in the age-adjusted model, men in the second (OR, 1.72; 95% CI, 1.14-2.59) and fourth (OR, 1.56; 95% CI, 1.03-2.35) quintiles, and women in the second (OR, 1.48; 95% CI, 1.08-2.04) quintile of the traditional dietary pattern were at higher risk for being diagnosed with uninvestigated reflux., Conclusion: Although the present study showed no statistically significant associations between major dietary patterns and the risk for uninvestigated reflux, relative positive associations were found between uninvestigated reflux and adherence to either fast food or traditional dietary patterns, suggesting that these contribute to the risk for developing reflux., (Crown Copyright © 2016.

The widespread popularity of new surgical technologies such as laparoscopy, thoracoscopy and robotics has led many surgeons to treat esophageal diseases with these methods. The expected benefits of minimally invasive surgery (MIS) mainly include reductions of postoperative complications, length of hospital stay, and pain and better cosmetic results. All of these benefits could potentially be of great interest when dealing with the esophagus due to the potentially severe complications that can occur after conventional surgery. Moreover, robotic platforms are expected to reduce many of the difficulties encountered during advanced laparoscopic and thoracoscopic procedures such as anastomotic reconstructions, accurate lymphadenectomies, and vascular sutures. Almost all esophageal diseases are approachable in a minimally invasive way, including diverticula, gastro-esophageal reflux disease, achalasia, perforations and cancer. Nevertheless, while the limits of MIS for benign esophageal diseases are mainly technical issues and costs, oncologic outcomes remain the cornerstone of any procedure to cure malignancies, for which the long-term results are critical. Furthermore, many of the minimally invasive esophageal operations should be compared to pharmacologic interventions and advanced pure endoscopic procedures; such a comparison requires a difficult literature analysis and leads to some confounding results of clinical trials. This review aims to examine the evidence for the use of MIS in both malignancies and more common benign disease of the esophagus, with a particular emphasis on future developments and ongoing areas of research.

Introduction: The management of gastro-esophageal reflux and esophagitis in infants and children is challenging, and there are currently no clear practice guidelines. Given a paucity of evidence in the treatment of pediatric esophagitis, there are concerns over both the efficacy and safety of proton-pump inhibitors, histamine type 2 receptor antagonists, and prokinetics., Areas Covered: Comprehensive data from randomized-controlled trials, meta-analyses and observational studies have helped to illustrate the efficacy and safety of various pharmacologic and non-pharmacologic treatments in pediatric esophagitis. We review the evidence on the risks of antacid therapy including bone mineral density, respiratory infections and enteric infections including necrotizing enterocolitis., Expert Opinion: Evidence pertaining to the safety of proton-pump inhibitors and histamine 2 receptor antagonists in pediatric populations is lacking. Largely based on small observational and randomized controlled trials, it does appear both antacids pose an increased risk of respiratory and enteric infections, which can occur even with a short course of treatment. The benefits of treatment, especially in pediatric esophagitis, must be weighed against the potential risks. More large-scale studies are needed to better quantify short-term and long-term risks of treatment. Anti-secretory medications, mostly proton pump inhibitors, have substantially improved the management of pediatric esophagitis. Nevertheless, because of possible infectious safety concerns, their use must be restricted to validated indications only.

Introduction: Barrett's esophagus (BE) is the only known precursor of adenocarcinoma occuring in the lower third of the esophagus. According to statistics, severity and elapsed time of gastroesophageal reflux disease (GERD) are major pathogenetic factors in the development of Barrett's esophagus., Patients and Methods: In a retrospective study between 2001 and 2008, we compared the preoperative results (signs and sympthoms, 24 hour pH manometry, esophageal manometry, Bilitec) and treatment efficacy of 176 GERD patients and 78 BE patients, who have undergone laparoscopic Nissen procedure for reflux disease., Results: The two groups of patients had similar demographic features, and elapsed time of reflux sympthoms were also equal. Both groups were admitted for surgery after a median time of 1.5 years (19.87 vs. 19.20 months) of ineffective medical (proton pump inhibitors) treatment. Preoperative functional tests showed a more severe presence of acid reflux in the BE group (DeMeester score 18.9 versus 41.9, p < 0.001). On the other hand, mano-metry - despite confirming lower esophageal sphincter (LES) damage - did not show difference between the two groups (12.10 vs. 12.57 mmHg, p = 0.892). We did not experience any mortality cases with laparoscopic antireflux procedures, although in two cases we had to convert during the operation (1 due to extensive adhesions, and 1 due to injury to the spleen). 3 months after the procedure - according to Visick score - both groups experienced a significant decrease, or lapse in reflux complaints (group I: 73%, group II: 81% of patients), LES functions improved (17.58 vs.18.70 mmHg), and the frequency and exposition of acid reflux decreased (DeMeester score 7.73 vs. 12.72)., Conclusion: The severity of abnormal acid reflux occuring parallel with the incompetent function of the damaged LES triggers not only inflammation in the gastroesophageal junction (GEJ), but also metaplastic process, and the development of Barrett's esophagus. Laparoscopic Nissen procedure for reflux disease can further improve outcome among patients with GERD not responding to conservative therapy.

Background and Objective: Respiratory function deteriorates over time after lung transplant. Reflux disease with pulmonary complications is a possible cause of this decline. This case series we aim to assess whether respiratory function improves after Nissen fundoplication in lung transplant patients and if surgery reduces gastroesophageal reflux disease (GERD) symptoms and use of proton pump inhibitors (PPIs)., Materials and Methods: A retrospective case series of lung transplant patients with reflux disease and Nissen fundoplication. Clinical symptoms, pH-metry data, use of PPIs were recorded before the procedure and up to 18 months postoperatively. The FEV1 values before and after Nissen fundoplication were recorded at 3 monthly intervals. Patients' satisfaction scores were recorded before operation and postoperatively., Results: A total of 64 lung transplant patients were selected. After Nissen fundoplication, the pH studies were done on 26 patients. The mean overall acid exposure fraction was 1.03% (P<0.05). FEV1 declined for 6 months postoperatively and then gradually improved. The comparison of FEV1 at 3 months preoperatively to 3 months postoperatively showed no significant difference (P=0.067) as well as at 6 months. A significant improvement in clinical GERD symptoms was achieved after antireflux surgery; however, the patients remained receiving PPIs., Conclusions: NF has been established as a safe operation for lung transplant patients. Late Nissen fundoplication did not improve lung function significantly amongst lung transplanted patients; however, patients with symptomatic GERD may have benefited from Nissen fundoplication in terms of symptom relief. A multicenter randomized control trial is needed to assess the effect of early unselected reflux control on respiratory function and graft survival., (Copyright © 2014 Lithuanian University of Health Sciences.

The stratified squamous epithelium of the esophagus forms a tight protective barrier. Defects of the barrier function contribute to gastroesophageal reflux disease (GERD), which is manifested as damage to the esophageal epithelium due to exposure to the gastrointestinal refluxate. In this review, we discuss the involvement of NFkB and Nrf2 in esophageal epithelial barrier function. Understanding these molecular pathways in the esophagus may help us develop therapeutic strategies to improve clinical outcomes in patients with GERD.
