However, studies on the natural history of treated RE are few. Although proton pump inhibitors(PPIs) as the first-line treatment provide notable symptomatic relief, disordered gut microbiota has been observed among PPI users. Probiotics are commonly administered to patients to regulate the disordered intestinal flora.AIM To evaluate the therapeutic effects in RE patients treated with a combination of esomeprazole and probiotics [Bacillus subtilis(B. subtilis) and Enterococcus faecium(E. faecium)].METHODS One hundred and thirty-four RE patients were randomized into two groups of 67 subjects each. The probiotics group was administered with esomeprazole 20 mg b.i.d. and live combined B. subtilis and E. faecium enteric-coated capsules 500 mg t.i.d. for eight weeks; the placebo group was administered with esomeprazole 20 mg b.i.d. and placebo for eight weeks. Subsequently, 12-wk follow-up was carried out on patients who achieved both endoscopic and clinical cure. Endoscopy,reflux diagnostic questionnaire(RDQ), gastrointestinal symptom rating scale(GSRS), and lactulose hydrogen breath test were performed to evaluate the therapeutic effects. A difference of P < 0.05 was considered statistically significant.RESULTSSixty-six patients in the probiotics group and 64 patients in the placebo group completed the 8-wk treatment. The healing rate and RDQ score had no significant difference between the two groups(P > 0.05). However, the GSRS diarrhea syndrome score was decreased significantly in the probiotics group(P = 0.002),and the small intestinal bacterial overgrowth negative rate in the probiotics group was significantly higher than that in the placebo group(P = 0.002). Of 114 endoscopically and clinically cured patients, 96 completed the follow-up. The logrank test showed that the time to relapse was shorter in the placebo group than in the probiotics group(P = 0.041). Furthermore, the therapy had a significant influence on relapse time, and the risk of relapse in the probiotics group was lower than that in the placebo group at any time point during the 12-wk followup(hazard ratio = 0.52, P = 0.033).CONCLUSION Esomeprazole combined with probiotics(B. subtilis and E. faecium) have a beneficial effect on RE treatment and patient management.展开更多

We report a case of a 56-year-old female patient without chronic degenerative pathologies with a history of non-severe acute SARS-CoV-2 infection that occurred two months prior to her presentation, treated with prednisone and betamethasone orally and inhaled, respectively for 21 days. The pivotal symptom is dysphagia and definitive diagnosis requires a tissue culture of the affected organ or a biopsy that shows the classic sulfur granules. Currently, antibiotic treatment with beta-lactams, such as amoxicillin/clavulanic acid, is still effective, as it was in our patient.展开更多

Methods:1247 patients with RE were diagnosed in our hospital endoscopy center from September 2010 to August 2012. The general information of the patients and the relationship between endoscopic classification and concomitant diseases were analyzed. Results: According to the endoscopic findings, 1247 subjects (4.70%) were found to have RE:932 (74.74%) males and 315 (25.26%) females, and the male to female ratio was 2.96:1. The peak age of prevalence was 50 to 59 (27.35%) which is followed by 40 to 49 (23.10%). In this study, most of the patients had a mild degree of esophagitis representing LA-A in 60.63% and LA-B in 34.24%. The antrum hyperemia was found in 291 patients with esophagitis (23.34%), followed by antrum erosion (20.13%) and hatal hernia (15.88%). There is no statistically significant relevance between Helicobacter pylori infection and RE (P > 0.05), but Barrett’s esophagus, duodenal ulcer, gastroesophageal tumors, a history of gastroesophageal surgery and antrum hyperemia were found to be associated with RE (P . Conclusion: The prevalence rate of endoscopic RE in our study was 4.70%, and most patients had a mild grade esophagitis. Male, advanced age, Barrett’s esophagus, duodenal ulcer, gastroesophageal tumors and a history of gastroesophageal surgery are the risk factors of esophagitis. Antrum hyperemia may reduce the severity of RE.展开更多

文摘Eosinophilic oesophagitis(EoE)is an allergen/immune-mediated chronic esophageal disease characterized by esophageal mucosal eosinophilic infiltration and esophageal dysfunction.Although the disease was originally attributed to a delayed allergic reaction to allergens and a Th2-type immune response,the exact pathogenesis is complex,and the efficacy of existing treatments is unsatisfactory.Therefore,the study of the pathophysiological process of EOE has received increasing attention.Animal models have been used extensively to study the molecular mechanism of EOE pathogenesis and also provide a preclinical platform for human clinical intervention studies of novel therapeutic agents.To maximize the use of existing animal models of EOE,it is important to understand the advantages or limitations of each modeling approach.This paper systematically describes the selection of experimental animals,types of allergens,and methods of sensitization and excitation during the preparation of animal models of EoE.It also discusses the utility and shortcomings of each model with the aim of providing the latest perspectives on EoE models and leading to better choices of animal models.
文摘Achalasia cardia,the most prevalent primary esophageal motility disorder,is predominantly characterized by symptoms of dysphagia and regurgitation.The principal therapeutic approaches for achalasia encompass pneumatic dilatation(PD),Heller's myotomy,and the more recent per-oral endoscopic myotomy(POEM).POEM has been substantiated as a safe and efficacious modality for the management of achalasia.Although POEM demonstrates superior efficacy compared to PD and an efficacy parallel to Heller's myotomy,the incidence of gastroesophageal reflux disease(GERD)following POEM is notably higher than with the aforementioned techniques.While symptomatic reflux post-POEM is relatively infrequent,the significant occurrence of erosive esophagitis and heightened esophageal acid exposure necessitates vigilant monitoring to preclude long-term GERD-related complications.Contemporary advancements in the field have enhanced our comprehension of the risk factors,diagnostic methodologies,preventative strategies,and therapeutic management of GERD subsequent to POEM.This review focuses on the limitations inherent in the 24-h pH study for evaluating post-POEM reflux,potential modifications in the POEM technique to mitigate GERD risk,and the strategies for managing reflux following POEM.

文摘BACKGROUND Multiple primary carcinomas(MPCs)are defined as two or more independent primary cancers that occur simultaneously or sequentially in the same individual.Synchronous MPCs are rarer than solitary cancers or metachronous MPCs.Accurate diagnoses of synchronous MPCs and the choice of treatment are critical for successful outcomes in these cases.CASE SUMMARY A 64-year-old patient presented with dysphagia,without obvious cause.A diagnosis of synchronous esophageal squamous cell carcinoma and colon adenocarcinoma with liver metastasis was confirmed based on examination and laboratory results.After multi-disciplinary consultations,combination chemotherapy(a 3-wk cycle with oxaliplatin 212 mg administered on day 1 and capecitabine 1.5 g twice daily on days 1-14)and esophageal cancer radiotherapy were initiated.Based on the results of genetic testing,we switched to a regimen of leucovorin+fluorouracil+oxaliplatin and cetuximab regimen for 8 cycles.Subsequently,capecitabine and bevacizumab were administered until the most recent follow-up,at which the tumor remained stable.CONCLUSION Successful cetuximab chemotherapy treatment provides a reference for the nonoperative and homogeneous treatment of different pathological types of synchronous MCPs.
文摘BACKGROUND Gastroesophageal reflux disease(GERD)is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage.Wendan Decoction(WDD)is a traditional Chinese herbal formula used to treat various gastrointestinal disorders,such as gastritis,functional dyspepsia,and irritable bowel syndrome.Mosapride,a prokinetic agent,functions as a selective 5-hydroxytryptamine 4 agonist,enhancing gastrointestinal motility.AIM To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.METHODS Eighty patients with GERD were randomly divided into treatment(receiving WDD combined with mosapride)and control(receiving mosapride alone)groups.The treatment was conducted from January 2021 to January 2023.The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire(RDQ).The secondary outcomes were improved esophageal motility(measured using esophageal manometry),gastric emptying(measured using gastric scintigraphy),and quality of life[measured via the Short Form-36(SF-36)Health Survey].RESULTS The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters,such as lower esophageal sphincter pressure,peristaltic amplitude,and peristaltic velocity compared to the control group.The treatment group showed significantly higher gastric emptying rates and SF-36 scores(in both physical and mental domains)compared to the control group.No serious adverse effects were observed in either group.CONCLUSION WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery.It can improve GERD symptoms,esophageal motility,gastric emptying,and the quality of life of patients.Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings.
文摘BACKGROUND Acute esophageal mucosal lesions(AEMLs)are an underrecognized and largely unexplored disease.Endoscopic findings are similar,and a higher percentage of AEML could be misdiagnosed as reflux esophagitis Los Angeles classification grade D(RE-D).These diseases could have different pathologies and require different treatments.AIM To compare AEML and RE-D to confirm that the two diseases are different from each other and to clarify the clinical features of AEML.METHODS We selected emergency endoscopic cases of upper gastrointestinal bleeding with circumferential esophageal mucosal injury and classified them into AEML and RE-D groups according to the mucosal injury’s shape on the oral side.We examined patient background,blood sampling data,comorbidities at onset,endoscopic characteristics,and outcomes in each group.RESULTS Among the emergency cases,the AEML and RE-D groups had 105(3.1%)and 48(1.4%)cases,respectively.Multiple variables exhibited significantly different results,indicating that these two diseases are distinct.The clinical features of AEML consisted of more comorbidities[risk ratio(RR):3.10;95%confidence interval(CI):1.68–5.71;P<0.001]and less endoscopic hemostasis compared with RE-D(RR:0.25;95%CI:0.10–0.63;P<0.001).Mortality during hospitalization was higher in the AEML group(RR:3.43;95%CI:0.82–14.40;P=0.094),and stenosis developed only in the AEML group.CONCLUSION AEML and RE-D were clearly distinct diseases with different clinical features.AEML may be more common than assumed,and the potential for its presence should be taken into account in cases of upper gastrointestinal bleeding with comorbidities.

文摘The occurrence of gastroesophageal reflux disease is common in the human population.Almost all cases of esophageal adenocarcinoma are derived from Barrett's esophagus,which is a complication of esophageal adenocarcinoma precancerous lesions.Chronic exposure of the esophagus to gastroduodenal intestinal fluid is an important determinant factor in the development of Barrett's esophagus.The replacement of normal squamous epithelium with specific columnar epithelium in the lower esophagus induced by the chronic exposure to gastroduodenal fluid could lead to intestinal metaplasia,which is closely associated with the development of esophageal adenocarcinoma.However,the exact mechanism of injury is not completely understood.Various animal models of the developmental mechanisms of disease,and theoretical and clinical effects of drug treatment have been widely used in research.Recently,animal models employed in studies on gastroesophageal reflux injury have allowed significant progress.The advantage of using animal models lies in the ability to accurately control the experimental conditions for better evaluation of results.In this article,various modeling methods are reviewed,with discussion of the major findings on the developmental mechanism of Barrett's esophagus,which should help to develop better prevention and treatment strategies for Barrett's esophagus.

文摘BACKGROUND Reflux esophagitis(RE) is a common digestive disorder, and its frequent recurrences cause significant physical pain and are financially burdensome to patients. However, studies on the natural history of treated RE are few. Although proton pump inhibitors(PPIs) as the first-line treatment provide notable symptomatic relief, disordered gut microbiota has been observed among PPI users. Probiotics are commonly administered to patients to regulate the disordered intestinal flora.AIM To evaluate the therapeutic effects in RE patients treated with a combination of esomeprazole and probiotics [Bacillus subtilis(B. subtilis) and Enterococcus faecium(E. faecium)].METHODS One hundred and thirty-four RE patients were randomized into two groups of 67 subjects each. The probiotics group was administered with esomeprazole 20 mg b.i.d. and live combined B. subtilis and E. faecium enteric-coated capsules 500 mg t.i.d. for eight weeks; the placebo group was administered with esomeprazole 20 mg b.i.d. and placebo for eight weeks. Subsequently, 12-wk follow-up was carried out on patients who achieved both endoscopic and clinical cure. Endoscopy,reflux diagnostic questionnaire(RDQ), gastrointestinal symptom rating scale(GSRS), and lactulose hydrogen breath test were performed to evaluate the therapeutic effects. A difference of P < 0.05 was considered statistically significant.RESULTSSixty-six patients in the probiotics group and 64 patients in the placebo group completed the 8-wk treatment. The healing rate and RDQ score had no significant difference between the two groups(P > 0.05). However, the GSRS diarrhea syndrome score was decreased significantly in the probiotics group(P = 0.002),and the small intestinal bacterial overgrowth negative rate in the probiotics group was significantly higher than that in the placebo group(P = 0.002). Of 114 endoscopically and clinically cured patients, 96 completed the follow-up. The logrank test showed that the time to relapse was shorter in the placebo group than in the probiotics group(P = 0.041). Furthermore, the therapy had a significant influence on relapse time, and the risk of relapse in the probiotics group was lower than that in the placebo group at any time point during the 12-wk followup(hazard ratio = 0.52, P = 0.033).CONCLUSION Esomeprazole combined with probiotics(B. subtilis and E. faecium) have a beneficial effect on RE treatment and patient management.
文摘BACKGROUND Gastroesophageal reflux is associated with poorer outcomes after lung transplant,likely through recurrent aspiration and allograft injury.Although prior studies have demonstrated a relationship between impedance-pH results and transplant outcomes,the role of esophageal manometry in the assessment of lung transplant patients remains debated,and the impact of esophageal dysmotility on transplant outcomes is unclear.Of particular interest is ineffective esophageal motility(IEM)and its associated impact on esophageal clearance.AIM To assess the relationship between pre-transplant IEM diagnosis and acute rejection after lung transplantation.METHODS This was a retrospective cohort study of lung transplant recipients at a tertiary care center between 2007 and 2018.Patients with pre-transplant anti-reflux surgery were excluded.Manometric and reflux diagnoses were recorded from pre-transplant esophageal function testing.Time-to-event analysis using Cox proportional hazards model was applied to evaluate outcome of first episode of acute cellular rejection,defined histologically per International Society of Heart and Lung Transplantation guidelines.Subjects not meeting this endpoint were censored at time of post-transplant anti-reflux surgery,last clinic visit,or death.Fisher’s exact test for binary variables and student’s t-test for continuous variables were performed to assess for differences between groups.RESULTS Of 184 subjects(54%men,mean age:58,follow-up:443 person-years)met criteria for inclusion.Interstitial pulmonary fibrosis represented the predominant pulmonary diagnosis(41%).During the follow-up period,60 subjects(33.5%)developed acute rejection.The all-cause mortality was 16.3%.Time-to-event univariate analyses demonstrated significant association between IEM and acute rejection[hazard ratio(HR):1.984,95%CI:1.03-3.30,P=0.04],confirmed on Kaplan-Meier curve.On multivariable analysis,IEM remained independently associated with acute rejection,even after controlling for potential confounders such as the presence of acid and nonacid reflux(HR:2.20,95%CI:1.18-4.11,P=0.01).Nonacid reflux was also independently associated with acute rejection on both univariate(HR:2.16,95%CI:1.26-3.72,P=0.005)and multivariable analyses(HR:2.10,95%CI:1.21-3.64,P=0.009),adjusting for the presence of IEM.CONCLUSION Pre-transplant IEM was associated with acute rejection after transplantation,even after controlling for acid and nonacid reflux.Esophageal motility testing may be considered in lung transplant to predict outcomes.
文摘We present an unusual case of esophageal actinomycosis that developed in a patient with normal immunity and a history of acute SARS-CoV-2 infection. We report a case of a 56-year-old female patient without chronic degenerative pathologies with a history of non-severe acute SARS-CoV-2 infection that occurred two months prior to her presentation, treated with prednisone and betamethasone orally and inhaled, respectively for 21 days. The pivotal symptom is dysphagia and definitive diagnosis requires a tissue culture of the affected organ or a biopsy that shows the classic sulfur granules. Currently, antibiotic treatment with beta-lactams, such as amoxicillin/clavulanic acid, is still effective, as it was in our patient.
文摘Aim: To summarize and analyze the clinical and endoscopic parameters in patients with reflux esophagitis(RE). Methods:1247 patients with RE were diagnosed in our hospital endoscopy center from September 2010 to August 2012. The general information of the patients and the relationship between endoscopic classification and concomitant diseases were analyzed. Results: According to the endoscopic findings, 1247 subjects (4.70%) were found to have RE:932 (74.74%) males and 315 (25.26%) females, and the male to female ratio was 2.96:1. The peak age of prevalence was 50 to 59 (27.35%) which is followed by 40 to 49 (23.10%). In this study, most of the patients had a mild degree of esophagitis representing LA-A in 60.63% and LA-B in 34.24%. The antrum hyperemia was found in 291 patients with esophagitis (23.34%), followed by antrum erosion (20.13%) and hatal hernia (15.88%). There is no statistically significant relevance between Helicobacter pylori infection and RE (P > 0.05), but Barrett’s esophagus, duodenal ulcer, gastroesophageal tumors, a history of gastroesophageal surgery and antrum hyperemia were found to be associated with RE (P . Conclusion: The prevalence rate of endoscopic RE in our study was 4.70%, and most patients had a mild grade esophagitis. Male, advanced age, Barrett’s esophagus, duodenal ulcer, gastroesophageal tumors and a history of gastroesophageal surgery are the risk factors of esophagitis. Antrum hyperemia may reduce the severity of RE.

文摘Gastroesophageal reflux(GER)in children is very common and refers to the involuntary passage of gastric contents into the esophagus.This is often physiological and managed conservatively.In contrast,GER disease(GERD)is a less common pathologic process causing troublesome symptoms,which may need medical management.Apart from abnormal transient relaxations of the lower esophageal sphincter,other factors that play a role in the pathogenesis of GERD include defects in esophageal mucosal defense,impaired esophageal and gastric motility and clearance,as well as anatomical defects of the lower esophageal reflux barrier such as hiatal hernia.The clinical manifestations of GERD in young children are varied and nonspecific prompting the necessity for careful diagnostic evaluation.Management should be targeted to the underlying aetiopathogenesis and to limit complications of GERD.The following review focuses on up-to-date information regarding of the pathogenesis,diagnostic evaluation and management of GERD in children.
文摘BACKGROUND Eosinophilic esophagitis(EoE)is an eosinophilic-predominant inflammation of the esophagus diagnosed by upper endoscopy and biopsies.A non-invasive and cost-effective alternative for management of EoE is being researched.Previous studies assessing utility of fractional exhaled nitric oxide(FeNO)in EoE were low powered.None investigated the contribution of eosinophilic inflammation of the stomach and duodenum to FeNO.AIM To assess the utility of FeNO as a non-invasive biomarker of esophageal eosinophilic inflammation for monitoring disease activity.METHODS Patients aged 6-21 years undergoing scheduled upper endoscopy with biopsy for suspected EoE were recruited in our observational study.Patients on steroids and with persistent asthma requiring daily controller medication were excluded.FeNO measurements were obtained in duplicate using a chemiluminescence nitric oxide analyzer(NIOX MINO,Aerocrine,Inc.;Stockholm,Sweden)prior to endoscopy.Based on the esophageal peak eosinophil count(PEC)/high power field on biopsy,patients were classified as EoE(PEC≥15)or control(PEC≤14).Mean FeNO levels were correlated with presence or absence of EoE,eosinophil counts on esophageal biopsy,and abnormal downstream eosinophilia in the stomach(PEC≥10)and duodenum(PEC≥20).Wilcoxon rank-sum test,Spearman correlation,and logistic regression were used for analysis.P value<0.05 was considered significant.RESULTS We recruited a total of 134 patients,of which 45 were diagnosed with EoE by histopathology.The median interquartile range FeNO level was 17 parts per billion(11-37,range:7-81)in the EoE group and 12 parts per billion(8-19,range:5-71)in the control group.After adjusting for atopic diseases,EoE patients had significantly higher FeNO levels as compared to patients without EoE(Z=3.33,P<0.001).A weak yet statistically significant positive association was found between the number of esophageal eosinophils and FeNO levels(r=0.30,P<0.005).On subgroup analysis within the EoE cohort,higher FeNO levels were noted in patients with abnormal gastric(n=23,18 vs 15)and duodenal eosinophilia(n=28,21 vs 14);however,the difference was not statistically significant.CONCLUSION After ruling out atopy as possible confounder,we found significantly higher FeNO levels in the EoE cohort than in the control group.
