Barrett’s esophagus (BE) is currently recognized as a precancerous lesion of esophageal adenocarcinoma. Gender, age, obesity, smoking and some other factors are closely related to BE, but the exact pathogenesis is still unclear. Gastrointestinal microecology is of great significance to the human body. It is closely related to human immunity, tumor, chronic inflammation, nutrient absorption, material metabolism. It may be closely related to the occurrence and development of BE. This article reviews the research progress of the relationship between BE and gastrointestinal microecology, aiming to provide a basis for further clarifying the pathogenesis of BE and targeting intervention in BE.
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.
Non-erosive gastroesophageal reflux disease (NERD) refers to a disease with symptoms such as acid reflux, heartburn and pathological reflux, but no significant esophageal mucosal damage under endoscopy. Its pathogenesis may be related to factors such as lower esophageal sphincter dysfunction, weakened esophageal clearance ability, visceral hypersensitivity, and disordered intestinal microecology, but the specific mechanism is still unclear. Small intestinal bacterial overgrowth (SIBO) is a common intestinal flora disorder syndrome. A number of studies have shown that SIBO has a certain correlation with NERD, and SIBO may be involved in the occurrence and development of NERD through mechanisms such as inflammatory response, gas production, and increased short-chain fatty acids. Therefore, this article reviews the correlation between NERD and SIBO, aiming to provide new ideas for the diagnosis and treatment of NERD.
【摘要】目的 探討胃食反流管病(GERD)患者牙周疾病的發生情況,以及GERD與牙周炎之間的關系。方法2008年7月2009年6月對360例GERD患者,396名正常人進行牙周健康狀況和全身一般情況檢查,牙周檢查以社區牙周指數(CPI)和附著喪失(AL)作為診斷標準。結果GERD患者牙周炎患病率及嚴重程度、牙列缺損率及缺牙數目均高于正常人, GERD患者無牙頜比例高于正常人。結論長期患GERD可能是牙周病的危險因素。
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.
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％。
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.
