ObjectiveTo develop an experimental model of gastroesophageal reflux-induced esophageal stricture in rats and explore the mechanism of esophageal stricture. MethodsA total of 30 male Sprague-Dawley (SD) rats by random number table method were randomly divided into three groups as follows: an operation+acid perfusion group, first the models of lower esophageal sphincter relaxation and hiatal hernia were made, and then the rats’ esophagus were perfused with hydrochloric acid-pepsin; acid perfusion group, the rats’ esophagus were directly perfused with hydrochloric acid-pepsin; and control group, rats’ esophagus were perfused with normal saline. After 4 weeks of continuous perfusion, the esophageal mucosal injury of SD rats in each group were observed, and the concentrations of inflammatory cytokines [tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-18] in esophageal tissues were detected by enzyme-linked immunosorbent assay. ResultsIn the operation+acid perfusion group, esophageal stricture was formed in 2 SD rats, but no esophageal stenosis was found in the acid perfusion group and the control group. The body weight of rats in the operation+acid perfusion group and the acid perfusion group were lower than that in the control group (P<0.05). The esophageal mucosal injury scores of rats in the operation+acid perfusion group and the acid perfusion group were higher than that in the control group (P<0.001), and the operation+acid perfusion group was higher than that in the acid perfusion group (P=0.014). The concentrations of TNF-α, IL-1β and IL-18 in esophageal tissues were higher in the operation+acid perfusion group and the acid perfusion group than that in the control group (P<0.001), and the operation+acid perfusion group was higher than that in the acid perfusion group (P<0.001). ConclusionsThe anti-reflux barrier is an important part of preventing gastroesophageal reflux disease. The destruction of anti-reflux barrier, hydrochloric acid-pepsin perfusion and inflammatory cytokines jointly induced esophageal inflammation and injury, and even caused esophageal stricture.
ObjectiveTo investigate the short-term effects of Da Vinci robot-assisted Nissen fundoplication in the treatment of refractory gastroesophageal reflux disease (rGERD), and to evaluate the safety and efficacy of its surgical treatment.MethodsA total of 40 patients with rGERD treated by Da Vinci robot-assisted surgery from October 2016 to November 2019 in our hospital were collected. There were 23 males and 17 females at age of 34-76 (61±23) years. The related clinical data were retrospectively analyzed, and the operation skills of Da Vinci robot-assisted Nissen fundoplication with rGERD were summarized.ResultsThere was no perioperative death or serious complication such as esophagogastric fistula. Postoperative reflux symptoms were significantly improved. DeMeester scores after surgery (39.79±35.01 points vs. 2.61±2.40 points, P=0.029), lower esophageal sphincter pressure (8.74±7.21 mm Hg vs. 24.56±8.76 mm Hg, P=0.020), integrated relaxation pressure (7.29±7.21 mm Hg vs. 16.49±9.99 mm Hg, P=0.023), distal contractile integral (600.49 ± 665.30 mm Hg·s·m vs. 510.99 ± 580.60 mm Hg·s·m, P=0.042), GERD-Q scale score (12.98±2.39 points vs. 7.59±1.11 points, P=0.033) were significantly improved compared with those before surgery. Postoperative dysphagia was found in 2 patients. And dysphagia was alleviated after diet adjustment and other treatments.ConclusionDa Vinci robot-assisted Nissen fundoplication is a safe and effective treatment for rGERD.
胃食管反流(GER)是指胃酸和其他胃內容物反流進入食管，正常人存在一定程度的反流，稱為生理性反流。GER 可以引起臨床癥狀，甚至組織病理學的改變。當出現胃燒灼、反酸、胸骨后疼痛等臨床癥狀和(或)組織病理學的改變時，也被稱為胃食管反流病(GERD)。以慢性咳嗽為主要臨床表現的GERD稱為胃食管反流性咳嗽(GERC)。2006年蒙特利爾會議提出了反流性咳嗽綜合征的定義 。GERC 是慢性咳嗽的常見原因，發生率為5％~41％ ，存在一定的地區差異。歐美報道極為常見，而日本極為少見，國內 GERC占慢性咳嗽病因的12％。
ObjectivesTo systematically review the diagnostic value of GerdQ questionnaire for diagnosing the gastro-oesophageal reflux disease (GERD).MethodsPubMed, Web of Science, EBMR, CNKI, CBM, VIP and WanFang Data databases were searched to collect studies on the diagnostic value the GerdQ questionnaire in diagnosing the GERD from inception to January 1st 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by using Meta-Disc 1.4 software. We used the Stata 12.0 software to assess the publication bias with funnel plots.ResultsA total of 20 studies were enrolled, including 7 978 patients. Among them, 4 848 patients were confirmed with GERD. The results of meta-analysis showed that: a) The pooled sensitivity, specificity, +LR, ?LR, and DOR were 0.79 (95%CI 0.78 to 0.81), 0.66 (95%CI 0.65 to 0.68), 2.28 (95%CI 1.77 to 2.94), 0.37 (95%CI 0.27 to 0.52) and 6.34 (95%CI 3.59, 11.19), SROC(AUC) was 0.789 3, and Q* was 0.726 6. b) When the cut-off was 7, the diagnostic accuracy of GerdQ questionnaire for the GERD was the highest, and that of 9 was the second. c) The diagnostic accuracy of GerdQ questionnaire was higher when it was used in China.ConclusionsGerdQ questionnaire has a moderate accuracy for the diagnosis of GERD, which can be a useful complementary tool for diagnosing GERD, and can be popularized in clinical settings. Due to limitation of quantity and quality of included studies, the above conclusions requires verification by more high quality studies.
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.
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.
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.
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.
