Objective To analyze the relationship between neuroticism and gastroesophageal reflux disease (GERD) using the Mendelian randomization (MR) method. Methods Exposure and outcome data were downloaded from the Integrative Epidemiology Unit (IEU) database in August 2023, including summary statistics from genome-wide association studies (GWAS) for neuroticism (n=374 323) and GERD (n=602 604). MR was conducted using the weighted median method, MR-Egger method, inverse variance weighted method, weighted mode method, and simple mode method. The causal relationship between the two was assessed using odds ratio (OR), and sensitivity analyses were performed to ensure the accuracy of the results. ResultsNeuroticism was associated with an increased risk of GERD [OR=1.229, 95%CI (1.186, 1.274), P<0.001]. Similarly, GERD was associated with an increased risk of neuroticism [OR=1.786, 95%CI (1.623, 1.965), P<0.001]. Conclusion There is a bidirectional causal relationship between neuroticism and gastroesophageal reflux disease.
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.
ObjectiveTo summarize the mechanism of effects of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) and the research progress of LSG in combination with fundoplication on obesity with GERD. MethodThe literatures of studies relevant to relation between LSG and GERD and effect of LSG combined with fundoplication on obesity accompanying GERD at home and abroad were searched and reviewed. ResultsAlthough there was considerable disagreement over the effect of LSG on GERD, the evidence showed that the LSG alone might worsen the existing GERD or promote new GERD, which mainly due to the destruction of the lower esophageal sphincter, deactivation of His angle, elevated intragastric pressure, and shape of sleeve stomach. Currently, the LSG in combination with fundoplication had been gradually applied in the clinical treatment of obese patients with GERD. And the short-term results of follow-up showed that the effects of weight loss and anti-reflux could be obtained, which needed to be evaluated by more studies and longer follow-up. ConclusionsThere is a risk of worsening existing GERD or promoting new GERD after LSG surgery. The LSG in combination with fundoplication is safe and feasible, which not only makes up for the adverse effects of LSG only on GERD after surgery, but also achieves the same similar effect of weight loss as LSG, providing a new choice for obese patients with GERD.
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.
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 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.
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.
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.
