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.
Objective To evaluate preventive effectiveness of pocket esophagogastric anastomosis for postoperativeanastomotic leak，stricture and gastroesophageal reflux disease （GERD），and investigate clinical significance of Montreal definition and classification of GERD after esophageal reconstruction. Methods Clinical data of 1 078 patients whoreceived 2 different surgical procedures for resection of esophageal or cardiac carcinoma from June 2007 to June 2011 in our hospital were retrospectively analyzed. In the experimental group，there were 582 patients who received pocketesophagogastric anastomosis，including 403 male and 179 female patients with their age of 60.4±12.6 years. There were 399 patients with esophageal carcinoma and 183 patients with cardiac carcinoma，392 patients receiving esophagogastrostomyabove the aortic arch and 190 patients receiving esophagogastrostomy below the aortic arch respectively. In the control group，there were 496 patients who received conventional end-to-side esophagogastric anastomosis，including 343 male and 153 female patients with their age of 59.2±12.8 years. There were 322 patients with esophageal carcinoma and 174 patients with cardiac carcinoma，317 patients receiving esophagogastrostomy above the aortic arch and 179 patients receivingesophagogastrostomy below the aortic arch respectively. A survey questionnaire was made on the basis of relevant diagnosticstandards to investigate the incidence of postoperative anastomotic stricture and GERD of the 2 groups during follow-up.Results The incidence of postoperative anastomotic leak of the experimental group was significantly lower than that of the control group ［0% （0/582）versus 1.0% （5/496），χ2=5.835，P=0.016］. Patients in the experimental group had less severeGERD symptoms，and the percentage of patients who needed antacid therapy for extraesophageal symptoms of GERD ofthe experimental group was significantly lower than that of the control group ［1.6% （33/541） versus 12.6% （57/453），χ2=23.564，P=0.000］. The incidence of anastomotic stricture of the experimental group was significantly lower than that of thecontrol group ［0.9% （5/539） versus 7.3% （34/465），χ2=25.124，P=0.000］，and especially，the incidence of severe anastomoticstricture of the experimental group was significantly lower than that of the control group ［0% （0/539） versus 4.7% （22/465），χ2=24.883，P=0.000］. There was no statistical difference in five-year survival rate. Conclusion Pocket esophagogastric anastomosis is better than conventional end-to-side esophagogastric anastomosis for the prevention of postoperative anastomoticleak，stricture and GERD. Montreal definition and classification of GERD is suitable for the diagnosis of postoperativeGERD after esophageal reconstruction.
ObjectiveTo investigate the clinical effects of laparoscopic hiatus reconstruction with Bard Crurosoft patch associated with Nissen fundoplication in elderly patients with gastroesophageal reflux disease (GERD). MethodsFrom July 2006 to July 2009, 22 consecutive elderly patients （≥65 years） with GERD underwent laparoscopic hiatus reconstruction associated with Nissen fundoplication， 10 of them underwent laparoscopic Crurosoft patch hiatus reconstruction (hiatus diameter≥5 cm in 2 patients， lt;5 cm in 8 patients) and 12 underwent laparoscopic simple sutured hiatus reconstruction (hiatus diameter≥5 cm in 2 patients， lt;5 cm in 10 patients). Intra and perioperative data including symptoms (heartburn, regurgitation, dysphagia, and respiratory complications), functional evaluations (esophagogastroscopy, manometric evaluations in lower esophageal segment, and 24 h pH-monitoring values) were compared and analyzed. ResultsPatients in 2 groups had similar preoperative values in demographics, symptom scores, functional evaluations, as well as operative data except for mean operative time. Three-month and 1-year follow-up after operation, the results of symptoms scores and functional evaluations of patients in 2 groups compared with preoperative values wear improved （Plt;0.05）, but symptoms scores and functional evaluations of patients in patch group were evaluated to demonstrate more significant improvement than suture group （Plt;0.05）. In suture group, the results of 3 months after operation were better than 1 year after operation, with statistically significant difference （Plt;0.05）. Two patients underwent postoperative intrathoracic immigration of wrap in suture group, but this complication did not happen in patch group （Plt;0.05）. ConclusionsLaparoscopic hiatus reconstruction with Bard Crurosoft patch associated with Nissen fundoplication is a safe and effective treatment for elderly patients(≥65 years) with GERD.
ObjectiveTo explore and analyze the clinical diagnosis and treatment of gastroesophageal reflux disease (GERD) which is manifested mainly as stubborn pharyngitis. MethodsFrom February 2010 to December 2012, 79 cases were diagnosed as stubborn pharyngitis and otolaryngology standard treatment was invalid. GERD questionnaire ratings and conventional endoscopy were performed for patients with obvious manifestations of stubborn pharyngitis shown on the laryngoscopy. They were randomly divided into treatment group (n=40) and control group (n=39). Patients in the treatment group accepted esomeprazole 40 mg, qd, for 12 weeks; and patients in the control group had sucralfate suspension 15 mL bid for 12 weeks. At the three observation points which are 4, 8, and 12 weeks after treatment began, clinical symptom score and pharyngeal inflammatory changes were recorded, and at the end of the treatment, all patients underwent endoscopy, and esophageal mucosal healing was observed. ResultsThere was no significant difference between the two groups of patients in terms of general data. After the treatment, the symptom scores were significantly decreased in the treatment group at the three observation points (P<0.05). The same situation happened also in the control group, but the difference was not significant (P>0.05). The symptom scores between the two groups after treatment were significantly different (P<0.5). And the effective rate for local pharyngeal infection was 83.9% and 41.4% in the treatment group and the control group respectively (P<0.05). ConclusionSome atypical GERDs feature by the symptoms of stubborn pharyngitis. Clinically, patients with long-term stubborn pharyngitis should be screened to exclude the possibility of GERD. esomeprazole therapy can significantly improve the pharyngitis symptoms and relieve local inflammation.
ObjectiveTo introduce the hiatal hernia (HH) and to summarize the research development of relationship between HH and respiratory symptoms. MethodsLiteratures in recent years which about relationship between HH and respiratory symptoms at home and abroad were collected and reviewed. ResultsGastroesophageal reflux disease (GERD), which always be caused by laryngeal airway and other esophageal symptoms, was a common illness and easily be misdiagnosed. One common symptom of the GERD was the HH. For those patients with reflux-associated esophageal symptoms, many of them suffered from HH. The treatment results showed that the endoscopic surgery could relieve the reflux symptom and effectively control the respiratory symptoms. ConclusionsThe HH can increase the risk of respiratory symptoms; an active treatment on the HH can relieve the respiratory symptoms, which is caused by the reflux symptom.
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 summarize basic research progress and current status of clinical diagnosis and therapy for gastroesophageal reflux disease. MethodRelated literatures were collected to review the pathogenesis, clinical manifestations, diagnosis and therapy of gastroesophageal reflux disease. ResultsGastroesophageal reflux disease was caused by many factors, such as hiatus hernia, hypotensive lower esophageal sphincter pressure, acid pocket, prolonged esophageal clearance, and delayed gastric emptying. Extra-esophageal symptoms was a common clinical presentation to gastroesophageal reflux disease. The diagnosis methods for gastroesophageal reflux disease included the symptom observation, gastroscopy examination, 24 h pH monitoring of esophageal, proton pump inhibitor test, questionnaire of gastroesophageal reflux disease and so on. The laparoscopic fundoplication could essentially treat the pathophysiologic abnormalities of gastroesophageal reflux disease, which had an obvious curative effect and wide application prospect. ConclusionPathogenesis, diagnosis, and therapy of gastroesophageal reflux disease are associated with multiple factors, which is still controversial and remains to be further studied.
Objective To investigate the gastrin level in patients with type 2 diabetes mellitus (T2DM) with gastroesophageal reflux disease (GERD), and analyze the possible mechanism of gastrin in the pathogenesis of T2DM combined with GERD. Methods Thirty-eight patients with T2DM combined with GERD treated between January 2013 and January 2015 were designated as group A; 40 patients with T2DM only were regarded as group B; 36 patients with GERD only were regarded as group C; and another 40 healthy volunteers who underwent physical examination at the same period were regarded as group D. The fasting serum levels of gastrin were measured and compared among the above four groups. Results The fasting serum level of gastrin was significantly higher in group A [(116.53±22.02) pg/mL] than group B [(101.89±20.76) pg/mL], group C [(90.04±21.16) pg/mL], and group D [(92.48±19.69) pg/mL] (P<0.01). The fasting serum level of gastrin in group B was significantly higher than group C and D (P<0.05). There was no significant difference between group C and D in terms of fasting serum level of gastrin (P>0.05). Conclusions There is a high level of gastrin in patients with GERD combined with T2DM. Abnormal secretion of gastrin may be closely related with the occurrence and development of T2DM and 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.
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.
