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.
ObjectiveTo analyze the causal relationship between the intake of cheese or tea and the risk of gastroesophageal reflux disease (GERD). MethodsUsing a two-sample Mendelian randomization approach, single nucleotide polymorphisms (SNPs) associated with milk or tea intake were used as instrumental variables. The causal effect of milk or tea intake on the risk of GERD was investigated using the MR Egger method, the weighted median method, the inverse-variance weighted (IVW) random-effects model, and the IVW fixed-effects model. Multivariable analysis was conducted using the MR Egger method, and leave-one-out sensitivity analysis was performed to validate the reliability of the data. ResultsCheese intake could reduce the occurrence of GERD [IVW random-effects model β=–1.010, 95%CI (0.265, 0.502), P<0.05], while tea intake could lead to the occurrence of GERD [IVW random-effects model β=0.288, 95%CI (1.062, 1.673), P<0.05]. ConclusionCheese intake may have a positive causal relationship with reducing the risk of GERD occurrence, while tea intake may have a positive causal relationship with increasing the risk of GERD occurrence.
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 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.
Objective To review the clinical experience of Heller myotomy for treatment of achalasia through a small thoracotomy. Methods Twenty-five patients with achalasia (9 moderate, 16 severe) underwent Heller myotomy without concomitant antireflux procedure through a small incision. A left thoracotomy was carried out through either the seventh or eighth intercostals space. The length of skin incision was 6 to 8 cm. Results There was no hospital death and severe postoperative complications. The mean operating time was 50 minutes. Mean hospital stay was 10 days. There was one intraoperative perforation and repaired successfully. All patients reported good to excellent relief of dysphagia and no symptom of gastroesophageal reflux after surgery. Eight patients were subsequently studied with a 24-hour esophageal pH monitoring and no evidence of pathologic reflux found. Conclusions Transthoracic Heller myotomy with a small incision is effective and safe method for treatment of achalasia with minimal invasion, quick recovery, less postoperative complication and shorter hospital stay. Proper extent of the myotomy may decrease the risk of subsequent gastroesophageal reflux in the postoperative period.
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.
ObjectiveTo present the safety and efficiency of laparoscopic Nissen fundoplication for hiatal hernia in elderly patients. MethodsClinical data of 35 elderly patients with hiatal hernia who underwent laparoscopic Nissen fundoplication in The Affiliated Hospital of Xuzhou Medical College between August 2013 and March 2014 was retrospectively analyzed. ResultsAll patients underwent laparoscopic Nissen fundoplication. The operation time was 72-minute in average (65-105 minutes) and intraoperative blood loss was 30 mL in average (10-120 mL). The mean value of postoperative hospital stay was 5-day (3-23 days). Patients' stomachs and esophagus were restored to normal position after surgery. No complication was noted except 2 patients had mild gastroesophageal reflux after operation, and 1 patient suffered from transient dysphagia after operation, all the symptoms subsided after conservative treatment. Afterwards, 33 of them achieved follow-up for 6 to 12 months (mean of 8.5 months), the other 2 patients were lost to follow-up. During the follow-up period, a questionnaire regarding to the criteria for Reflux Diagnostic Questionnaire (RDQ) score were conducted in the 33 patients, and the results showed that the symptoms including acid reflux, heartburn, chest pain, cough, dyspnea, lump sensation in the pharynx, and hoarseness were improved significantly in 6 months after operation (P<0.05), and no recurrence was found during the follow-up period. ConclusionLaparoscopic Nissen fundoplication is a safe operation for elderly patients with hiatal hernia, and it can achieve good clinical result.
ObjectiveTo evaluate laparoscopic anti-reflux surgery for treatment of chronic obstructive pulmonary disease (COPD) associated with gastroesophageal reflux disease (GERD).MethodsA total of 20 patients with GERD and COPD underwent laparoscopic anti-reflux procedure in the First Affiliated Hospital of Zhengzhou University from January 2016 to December 2017. The reflux diagnostic questionnaire, pulmonary function, COPD assessment test scale, 24-hour esophageal pH-impedance monitoring and esophageal pressure measurement were performed in all patients. All drug-refractory patients underwent the laparoscopic anti-reflux surgery. After 12 months follow-up, the parameters of COPD and GERD were evaluated again.ResultsTwenty patients with COPD and GERD were successfully performed laparoscopic anti-reflux surgery, no hernia patch repair patient and death patient occurred. There was no esophageal rupture, bleeding, infection, and other serious postoperative complications. Although 8 patients had the different degree dysphagia and 10 patients had the different degree abdominal distention, they all relieved themselves. Twenty patients with GERD and COPD were followed up for 1 year. Compared with the values before treatment, the GERD symptom score, reflux times, DeMeester score, and COPD assessment test score of the patients were significantly reduced (P<0.05), the lower esophageal sphincter pressure, percentage of forced expiratory volume in one second (FEV1) in the predicted value and FEV1/forced vital capacity (FVC) were significantly increased (P<0.05) after the treatment. According to the grading standard of The Global Initiative for Chronic Obstructive Lung Disease (GOLD), 5 cases of grade Ⅰ, 2 cases of grade Ⅱ and 1 case of grade Ⅲ were cured; 1 case of grade Ⅰ, 4 cases of grade Ⅱ and 4 cases of grade Ⅲ were improved; 1 case of grade Ⅰ, 1 case of grade Ⅱ and 1 case of grade Ⅳ were ineffective. The total effective rate was 85% (17/20).ConclusionsCOPD is closely related to GERD. Laparoscopic anti-reflux surgery can not only effectively treat GERD, but also markedly improve COPD.
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.
Abstract: Objective To evaluate the effect on gastroesophageal reflux and gastric emptying in the different route of gastroesophageal anastomosis objectively after esophagectomy for patients with midesophageal carcinoma. Methods Forty patients with midesophageal carcinoma were randomly divided into two groups. Esophageal bed group (n=20): the gastroesophageal anastomosis were performed while the stomach were pulled on through the esophageal bed after esophagectomy; endothoracic group (n=20): gastroesophageal anastomosis were performed while the stomach were pulled on in the thoracic cavity. Ten persons had no disease of digestive system and healthy volunteers were recruited as normal control group. 24-hour esophageal pH monitoring and radioisotope gastric emptying checkup were carried out in all experimental subjects 3 months after operation, so as to observe the changes of gastroesophageal reflux and gastric emptying. Results All of the patients’s operation were success. And no anastomotic leakage and no anastomotic stenosis. Three months after operation, the patients in both operation groups were with different level of reflux. DeMeester total appraise score, the times of regurgitation of gastric juice in 24h, gt;5 min reflux frequency, the longest time of keep reflux, pHlt;4.00 total time and pHlt;4.00 of total time percent, these targets in both operation groups were higher than those in control group (Plt;0.01) DeMeester total appraise score, the times of regurgitation of gastric juice in 24 hours, the longest time of keeping reflux, pHlt;4.00 of total time and pHlt;4.00 of total time percent in esophageal bed group were lower than those in endothoracic group(Plt;0.01). The recent period of gastric emptying percentage (GE) in both operative groups were lower than that in normal control group. GE in esophageal bed group experimental meal in the stomach after entering the 30,60,90,120,180 and 240 min were higher than those in endothoracic group. Conclusion After the operation of esophagogastric anastomosis through esophageal bed in upper aortic site,gastroesophageal reflux and delayed gastric emptying exist objectively, However, the technique is superior to the traditional technique to reduce the extent of gastroesophageal reflux and delayed gastric emptying, its mechanism might be the result of mechanical factors.
