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.
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.
Objective To systematically review the prognostic significance of extranodal extension in gastric cancer, esophageal cancer and gastroesophageal junction cancer. Methods We searched EMbase, The Cochrane Library (Issue 9, 2016), PubMed, CBM, CNKI, VIP and WanFang Data databases from inception to August 2016, to collect cohort studies about the prognostic significance of extranodal extension. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed by using RevMan 5.2 software. Results A total of 16 studies involving 9 445 participants were included. The results of meta-analysis showed that for gastric cancer patients, the overall survival (OS) (HR=1.71, 95%CI 1.49 to 2.00,P<0.000 01), disease free survival (DFS) (HR=1.39, 95%CI 1.12 to 1.73,P=0.003) and cancer specific survival (HR=1.52, 95%CI 1.18 to 1.96,P=0.001) in ENE(+) group were lower than ENE(–) group. For esophageal cancer and gastroesophageal junction cancer patients, the overall survival (OS) (HR=1.84, 95%CI 1.49 to 2.27,P<0.000 01), disease free survival (DFS) (HR=2.18, 95%CI 1.70 to 2.81,P<0.000 01) and cancer specific survival (HR=1.73, 95%CI 1.19 to 2.52,P=0.004) in ENE(+) group were lower than ENE(–) group. Conclusion Current evidence indicates that ENE(+) was correlated with a poor prognosis in gastric cancer, esophageal cancer and gastroesophageal junction cancer patients. Due to the quantity and quality limitations of included studies, more high quality cohort studies are needed to verify the above conclusions.
ObjectiveTo explore various exposure technology of gastroesophageal region and their advantages and disadvantages by laparoscopic surgery in upper abdominal. MethodThe related literatures on various exposure technology of gastroesophageal region by laparoscopic surgery in upper abdominal at home and abroad in recent years were collected and reviewed. ResultsNow, there were main three exposure technologies of gastroesophageal region by laparoscopic surgery in upper abdominal, including traditional retractor liver retraction, suspension liver retraction, and adhesion liver retraction. Each method had its own advantages and disadvantages. Conclusionthe most suitable exposure method of gastroesophageal region by laparoscopic surgery in upper abdominal should be selected according to situations of surgery and patient.
Objective To investigate the effect on motility function of remnant esophagus and intrathoracic stomach after esophagectomy for esophageal and cardiac carcinoma. Methods Thirty nine patients with esophageal and cardiac carcinoma were divided into two groups according to surgical procedure. Group of anastomosis above aortic arch （n = 21）： esophagogastrostomy was performed above the aortic arch in patients with esophageal carcinoma of the middle third; group of anastomosis below aortic arch（n= 18）： esophagogastrostomy was performed below the aortic arch in patients with esophageal carcinoma of the low third and cardiac carcinoma. Six health volunteers without gastroesophageal reflux were recruited as control group. Esophageal manometry and upper alimentary tract roentgenography were performed in all patients. Results There was a high pressure zone at the anastomotic orifice in parts of patients of both anastomosis groups. The resting pressure of remnant esophagus was higher than that in control group （P〈0. 05）, and similar to the resting pressure of intrathoracic stomach （P〉0. 05）. There was no significant difference in resting pressure of remnant esophagus and intrathoracic stomach between two anastomosis groups （P〉0.05）. The amplitude and number of primary peristalsis in remnant esophagus of group of anastomosis above aortic arch were significantly reduced in comparison with control group. The number of primary peristalsis in remnant esophagus of group of anastomosis above aortic arch was significantly lower than that of group of anastomosis below aortic arch （P〈0. 05）. The motility in the body of intrathoracic stomach was not observed. Weak motor activity of the gastric antrum was observed with upper alimentary tract roentgenography after surgery and evidently recovered 1 year after surgery. Conclusions The resting pressure of remnant esophagus and intrathoracic stomach is not influenced by the site of anastomosis. Esophagogastric anastomosis at the upper thorax is likely to result in poor motility of remnant esophagus. The motor activity of intrathoracic stomach becomes weak after esophagectomy and then recovers gradually over time, hut still fail to return to normal level.
Objective To investigate the different clinical features of chronic cough induced by rhinitis /sinusitis or gastro-esophageal reflux, and its significance for etiological diagnosis of chronic cough.Methods Chronic cough patients were recruited from respiratory medicine clinic in Chongqing Xinqiao Hospital from December 2009 to December 2010. Medical history, symptoms and signs were recorded from all selected patients. The patients with chronic rhinitis / sinusitis, but without gastro-esophageal reflux symptoms were suspected upper airway cough syndrome ( UACS) , and given chlorpheniramine, nasal decongestant, and corticosteroid treatment for 1 week. The patients with clinical symptoms associated with gastroesophageal reflux or with history of gastric diseases were suspected gastroesophaged reflux-related cough ( GERC) , were given esomeprazole ( 40 mg, bid) , combined prokinetic agent for 2 weeks. The patients were confirmed the diagnosis of UACS or GERC when their cough was relieved after the above targeted treatment.Results 114 patients were enrolled in this study. 47 patients were suspected GERC, of which 32 were confirmed, and 67 patients were suspected UACS, of which 43 were confirmed. There was no significant difference in age, duration of disease, severity of cough, proportion of night cough, proportion of clear throat symptom, or proportion of cobblestone sign between the UACS patients and the GERC patients ( P gt;0. 05) .There were more females in the GERC patients and more males in the UACS patients ( P lt; 0. 05) . Cough with sputum, throat symptoms and signs were more common in the UACS patients ( P lt;0. 05) . The hoarseness and sore throat symptoms were found only in the GERC patients, but postnasal drip symptoms were found only in the UACS patients. Conclusions Throat signs and symptoms are not completely similiar in the GERC and the UACS patients. Comprehensive judgments combining with patient history,characteristics of concurrent cough, throat symptoms, and signs can provide important references for the clinical diagnosis of chronic cough caused by rhinitis/ sinusitis or gastro-esophageal reflux.
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.
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 evaluate the efficacy of the subtotal splenectomy versus total splenectomy with gastroesophageal devascularization for patients of hepatic cirrhosis and portal hypertension. Methods We searched the Cochrane Library (Issue 2, 2008), MEDLINE (1966 to August, 2008), EMbase (1966 to August, 2008), the China Biological Medicine Database (1978 to August, 2008), Chinese Sci-tech Periodical Full-text Database (1989 to August, 2008) and Chinese Periodical Full-text Database (1994 to August, 2008), as well as hand-searched several related journals and conference proceedings for the randomized controlled trials involving the comparison of the efficacy of the subtotal splenectomy with the total splenectomy for the patients of the hepatic cirrhosis and portal hypertension. Results Three studies involving 136 patients were identified. The results of two studies indicated that both of the subtotal splenectomy increased less the peripheral platelet count and there was a statistically significant difference between the two groups [WMD= – 39.27, 95%CI (– 62.57, – 15.97)]. Two studies indicated that the serum tuftsin level was increased significantly after the subtotal splenectomy [WMD= 165.28, 95%CI (159.36, 171.21)]. One study indicated that both of the subtotal splenectomy and total splenectomy with gastroesophageal devascularization increased the peripheral white blood cell count and there was statistical difference between the two groups [WMD= – 0.93, 95%CI (– 1.52, – 0.34)]. There was no statistical difference in serum IgA level between the two groups. One study indicated the average fever time after the total splenectomy was longer than the subtotal splenectomy; there was statistical differences in 5 years survival rate between the two groups (Plt;0.05). Conclusions After the subtotal splenectomy the hypersplenism of patients suffered from hepatic cirrhosis and portal hypertension was corrected obviously and the blood cells were increased smoothly so that high blood viscosity was prevented and occurrence of the thrombotic diseases was decreased. And the immune system reserve functions of the patients with hepatic cirrhosis and portal hypertension were maintained. More randomized controlled trials, with large sample sizes, may lead to more accurate results.
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.
