Objective We aimed to evaluate the prevalence of H.pylori infection and the prevalence of cagA+ strains in patients with and without Barrett’s esophagus. Methods A full literature search to February 2008 was conducted in PubMed, MEDLINE and EMbase databases to identify case-control studies or cohort studies evaluating the prevalence of H.pylori in patients with or without Barrett’s esophagus. Summary odds ratios (OR) and 95% confidence interval (CI) were calculated by RevMan 4.2.8. Results Nineteen studies were identified (16 case-controlled studies and 3 cohort studies). In case controlled studies, the prevalence of H.pylori infection significantly decreased in patients with Barrett’s esophagus as compared subjects with normal endoscopic appearance, with a overall OR of 0.56 (95%CI 0.40 to 0.79). The prevalence of H.pylori infection was no statistically significant difference in patients with Barrett’s esophagus as compared to those with gastroesophageal reflux disease, with a overall OR of 0.86 (95% CI 0.74 to 1.00). In cohort studies, the prevalence of H. pylori was no statistically significant difference in patients with Barrett’s esophagus as compared to patients with normal endoscopic appearance or patients with gastroesophageal reflux disease, with a overall OR of 1.12 (95%CI 0.77 to 1.61) and 1.10 (95%CI 0.32 to 3.83). When the analysis was stratified by the status of cagA, the prevalence of cagA positive strains significantly decreased in patients with Barrett’s esophagus as compared both to subjects with normal endoscopic appearance with OR 0.30 and 95% CI 0.12 to 0.74, and to those with gastroesophageal reflux disease (OR 0.55; 95%CI 0.33 to 0.94). Irrespective of the presence of intestinal metaplasia, similar magnitude for the reduction of H.pylori infection was observed for patients with Barrett’s esophagus and those with normal endoscopic appearance. While accompared with the presence of intestinal metaplasia, Barrett’s esophagus was associated with a significantly reduction as compared to the patients with gastroesophageal reflux disease (OR 0.81, 95%CI 0.68 to 0.98). When stratified analyses were performed, a significant reduction of H.pylori infection was observed only in patients with long-segment Barrett’s esophagus (OR 0.54; 95%CI 0.35 to 0.82), but not in those with short-segment Barrett’s esophagus (OR 0.72; 95%CI 0.43 to 1.20). Conclusion This meta-analysis indicated that the prevalence of H.pylori infection, especially the prevalence of cagA positive strains was significantly lower in patients with Barrett’s esophagus than in subjects with normal endoscopic appearance. However, the prevalence of H. pylori infection was no statistical difference in patients with Barrett’s esophagus as compared to those with gastroesophageal reflux disease. Colonization with cagA positive strains may be protective against the formation of Barrett’s esophagus.
ObjectiveTo investigate the causal relationship between gastroesophageal reflux disease (GERD) and obstructive sleep apnea (OSA) with its typical symptoms (snoring and daytime sleepiness) by using Mendelian randomization (MR). MethodsThe inverse-variance weighted method was used as the main analysis method to assess the causal effect. Sensitivity and pleiotropy analyses were carried out using leave-one-out and MR-Egger analysis, and then heterogeneity tests were conducted. ResultsIn the MR analysis, genetically predicted GERD was associated with a greater risk of OSA (IVW: OR=1.528, 95%CI 1.374 to 1.699, P=5.315E?15). Additional MR results were consistent with the IVW results, and no pleiotropy or heterogeneity was found. We also discovered a significant causal relationship between GRED and snoring (IVW: OR=0.959, 95%CI 0.949 to 0.969, P=1.507E?15), and daytime sleepiness (IVW: OR=1.024, 95%CI 1.021 to 1.036, P=4.580E?5), with no evidence of pleiotropy. ConclusionThe MR study supports a causal effect between GERD and OSA with its typical symptoms (daytime sleepiness and snoring).
Objective To investigate the clinical characteristics of upper airway cough syndrome ( UACS) and the relationship of UACS with upper airway diseases, cough variant asthma ( CVA) , and gastroesophageal reflux disease ( GERD) . Methods 92 subjects with chronic cough and throat symptoms and signs were included in the study. The medical records were collected fromall subjects, and 49 subjects suspected for CVA undertook bronchial provocation test. Then the efficacy was evaluated and etiology were analyzed based on the efficacy of targeted treatment. Results Bronchial provocation test yielded positive results in 14 subjects suspected of CVA, accounting for 15. 2% of all cases ( 14/92) . 18. 5% ( 17 /92) of patients had a history of chronic gastritis or combined symptoms of GERD, of whom anti-gastroesophagealreflux treatment was effective. The patients with rhinitis, sinusitis history and/ or symptoms accounted for 33. 7% of cases ( 31 cases) . 51. 1% ( 47/92) of patients had only signs and symptoms of chronic pharyngitis. Conclusions UACS is not only due to the rhinitis and/ or sinusitis but also chronic pharyngitis. Chronic pharyngitis may be secondary to chronic rhinitis/ sinusitis with post nasal drip and gastroesophageal reflux, also may be an independent cause of chronic cough.
ObjectiveTo analyze the effect and prognosis of laparoscopic patch repair of esophageal hiatal hernia.MethodsFrom October 2014 to January 2019, 100 patients with gastroesophageal reflux disease undergoing laparoscopic esophageal hiatus hernia repair were randomly divided into the patch group and the non-patch group. All patients underwent laparoscopic repair of esophageal hiatal hernia plus fundoplication (Nissen’s method). On that basis, the patients in the patch group used special mesh for esophageal hiatal hernia repair, while the ones in the non-patch group did not. All the patients were followed up for a long time. The operative effect, postoperative complication rate, recurrence rate, and satisfaction rate of the patients between the two groups were compared.ResultsA total of 98 patients were successfully followed up for more than one year, including 68 in the patch group and 30 in the non-patch group. One year after surgery, the differences between the patch group and the non-patch group in the improvements of reflux attack, heartburn, dysphagia, and food intake were statistically significant (P<0.05); there was no significant difference between the patch group and the non-patch group in satisfaction rate (82.4% vs. 73.3%, P>0.05); the differences in recurrence rate (2.9% vs. 26.7%) and incidence of dysphagia (47.0% vs. 6.7%) between the patch group and the non-patch group were statistically significant (P<0.05).ConclusionFor the patients with gastroesophageal reflux disease caused by esophageal hiatal hernia, the laparoscopic repair of esophageal hiatal hernia + Nissen fundoplication on the basis of reasonable selection of special mesh for esophageal hiatal hernia can obtain satisfactory clinical effect.
ObjectiveTo investigate the individualized management of severe gastroesophageal reflux disease (GERD) secondary to scleroderma, particularly the safety and feasibility of laparoscopic Toupet fundoplication for this entity.
MethodsFrom June, 2011 to June, 2014 six inpatient cases had severe GERD secondary to scleroderma were documented. Endoscopy, esophageal high-resolution manometry and 24 hours reflux monitoring were applied for GERD evaluation. Maintenance of conservative treatment was carried out for the 2 cases who responsed well to medication therapy, laparoscopic Toupet fundoplication was done for the 4 cases who had extraesophageal symptom and not well controlled by medication. The patients were followed-up for an average of 2.2 years (1 to 4 years) after discharge, and endoscopic was rechecked during the followed-up.
ResultsThe esophageal symptom of regurgitation, heartburn and dysphagia, as well as the extraesophageal symptom of cough and asthma significantly relieved during followed-up, meanwhile the anti-reflux medication was reduced or stopped in all the patients. For the 4 surgical patient, one had partial recurrence and no complication occurred.
ConclusionsThe management of severe GERD secondary to scleroderma could follow the strategy of controlling the primary disease, living adjustment, anti-reflux medication and surgery step by step. The laparoscopic Toupet fundoplication may be safe, effective and feasible for the medication unmet patients, it deserves further studies.
ObjectiveTo explore clinical outcomes of complete mechanical cervical side-to-side esophago-gastric tube anastomosis.
MethodsClinical data of 60 patients with esophageal carcinoma (EC)who underwent complete mechanical cervical side-to-side esophago-gastric tube anastomosis in the 153rd Central Hospital of People's Liberation Army from June 2010 to June 2012 were retrospectively analyzed. There were 41 male and 19 female patients with their age of 46-78 (64.2±6.4)years and body weight of 58.6±12.6 kg. There were 39 patients with mid-thoracic EC, 15 patients with lower-thoracic EC, and 6 patients with upper-thoracic EC. There was 1 patient with stageⅠ EC, 32 patients with stage Ⅱ EC, 23 patients with stage Ⅲ EC, and 4 patients with stage Ⅳ EC. Six to 12 months after the operation, all the patients received a survey questionnaire regarding their quantity and quality of food intake as well as gastroesophageal reflux (GER). Fifty-two patients received barium swallow, and 38 patients received gastroscopy and esophageal mucosal biopsy during follow-up.
ResultsAll the 60 patients were successfully discharged. Average length of hospital stay was 12.0±2.6 days. Average time for anastomosis was 18.4±3.2 minutes. The incidence of anastomotic leak was 1.7% (1/60). During follow-up, all the 60 patients restored normal food intake, and 14 patients (23.3%)had GER symptoms. Barium swallow showed the average anastomotic diameter of 1.6±0.2 cm (range, 1.2 to 2.2 cm). In 45° trendelenburg position, 31 patients (59.6%)had barium GER, but none of the patients had prolonged barium retention, intrathoracic gastric dilation or disturbed gastric emptying. Gastroscopy of 38 patients showed full anastomotic opening in 24 patients (63.2%)and irregular or semiclosed anastomosis in the other 14 patients (36.8%). Mucosal biopsy under gastroscopy showed chronic inflammation in 18.4% (7/38)patients.
ConclusionComplete mechanical cervical side-to-side esophago-gastric tube anastomosis can significantly prevent anastomotic stenosis, leak and intrathoracic stomach symptoms with good clinical outcomes.
Gastroesophageal reflux disease (GERD) is a common, chronic disease of the digestive system. In recent years, endoluminal therapy for GERD has become a research hotspot. The reduced anti-reflux barrier function plays an important role in the occurrence of GERD. Peroral endoscopic therapy can improve the defect of anti-reflux barrier function. According to the involved layers, the endoscopic therapy can be classified as transmural which represented by transoral incisionless and transoral incisionless fundoplication, and non-transmural which represented by peroral endoscopic cardia constriction and radiofrequency ablation. This article reviews the progress of endoscopic non-full-thickness therapy for GERD in recent years, and introduces the action mechanism of peroral endoscopic therapy of GERD, the therapy of the mucosal layer and muscle layer of anti-reflux barrier, and other treatments. The purpose is to provide a reference for further exploring suitable endoscopic treatment of GERD.
ObjectivesTo systematically review the efficacy and safety of hydrotalcite in the treatment of reflux esophagitis (RE).MethodsCBM, CNKI, WanFang Data, VIP, PubMed, EMbase, The Cochrane Library, Web of Science and Scopus databases were searched online to collect randomized clinical trials (RCTs) of hydrotalcite or hydrotalcite plus PPI versus PPI alone in the treatment of RE from inception to June 30th, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was performed by RevMan 5.3 software.ResultsA total of 15 RCTs involving 1 655 patients were included. The results of meta-analysis showed that: after 4-8 weeks of treatment, there was no significant difference between hydrotalcite vs. PPI regarding RE healing rates (RR=0.87, 95%CI 0.76 to 1.00, P=0.05). However, there were significant increases in RE healing rate (RR=1.22, 95%CI 1.14 to 1.31, P<0.001) and symptom relief rate (RR=1.36, 95%CI 1.12 to 1.66,P<0.01) between hydrotalcite plus PPIvs. PPI alone. Similar increases of RE healing rate (RR=1.16, 95%CI 1.08 to 1.25, P<0.001) and symptom relief rate (RR=1.12, 95%CI 1.04 to 1.20,P<0.01) were seen in patients with refractory RE. No increase of adverse effect rate was shown with hydrotalcite or hydrotalcite plus PPI compared to PPI alone.ConclusionsCompared with PPI alone, hydrotalcite plus PPI confers a statistically significant improvement of healing rate and symptom relief rate, while it does not increase adverse effect rate. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To provide a reliable experimental model for gastroesophageal reflux (GER) study. Methods Twenty Japan 5-month-old male rabbits wererandomly divided into two groups: group cardiomyotomy(n=10), group partial cardiomyectomy(n=10). The operations of cardiomyotomy and parital cardiomyectomy were performed in 2 groups respectively. All the animals underwent intraesophagealpH detection 1 week before operation and 4 weeks after operation. The mean changes of reflux ratios were compared between before operation and after operation.Results In gastroesophageal reflux ratio between before operation and after operation, there was no significant difference in group cardiomyotomy (1.98%±1.52% and 4.32%±2.39%, Pgt;0.05) and there was significant difference in group partialcardiomyectomy（1.56%±1.57% and 13.56%±3.27%, Plt;0.05）. Conclusion The reliable experimental model of GER can be made with procedure of partial cardiomyectomy. It can be used in estimating the operative procedure of antireflux and is conducive to dynamic observation and study of esophagitis.
Objective To investigate the prevalence and predisposing factors of gastroesophageal reflux（GER）in patients with chronic obstructive pulmonary disease（COPD）and its impacts on the frequency of COPD exacerbations.Methods 50 patients with acute exacerbation of COPD were enrolled in the study.All patients filled a modified version of clinically validated standardized Mayo Clinic GER questionnaire.Pulmonary function tests（PFT），body mass index（BMI），serum albumin，and medications were recorded.The patients were divided in to GER group（13 patients with GER symptoms longer than one year and diagnosed GER by gastroscope） and non-GER group（37 patients without GER symptoms）.Results There were no significant differences in the BMI，serum albumin，use of inhaled steroids and theophylline between the two groups.Forced expiratory volume in one second as a percentage of the predicted value（FEV1%pred）（37% vs 38.3%，P=0.608.），residual volume % predicted（123.4 % vs 137.8%，P=0.222），and residual volume to total lung capacity（139.4% vs 141.5%，P=0.798） were not significantly different between the two groups.The number of COPD exacerbations per year was significantly higher in patients with GER compared to patients without GER（4.5 vs 1.3，P=0.006）.Conclusions The severity of airflow obstruction and the hyperinflation is unlikely to contribute to the development of GER.Patients with GER experience significantly more exacerbations per year when compared to patients without GER，suggesting more highlight warrant in treatment of GER in COPD patients.
