RESUMEN
INTRODUCTION: Visceral obesity is a risk factor for reflux esophagitis (RE). We investigated the risk of RE according to visceral adipose tissue (VAT) measured by deep neural network architecture using computed tomography (CT) and evaluated the longitudinal association between abdominal adipose tissue changes and the disease course of RE. METHODS: Individuals receiving health checkups who underwent esophagogastroduodenoscopy (EGD) and abdominal CT at Seoul National University Healthcare System Gangnam Center between 2015 and 2016 were included. Visceral and subcutaneous adipose tissue areas and volumes were measured using a deep neural network architecture and CT. The association between the abdominal adipose tissue area and volume and the risk of RE was evaluated. Participants who underwent follow-up EGD and abdominal CT were selected; the effects of changes in abdominal adipose tissue area and volume on RE endoscopic grade were investigated using Cox proportional hazards regression. RESULTS: We enrolled 6,570 patients who underwent EGD and abdominal CT on the same day. RE was associated with male sex, hypertension, diabetes, excessive alcohol intake, current smoking status, and levels of physical activity. The VAT area and volume increased the risk of RE dose-dependently. A decreasing VAT volume was significantly associated with improvement in RE endoscopic grade (hazard ratio: 3.22, 95% confidence interval: 1.82-5.71). Changes in subcutaneous adipose tissue volume and the disease course of RE were not significantly correlated. DISCUSSION: Visceral obesity is strongly associated with RE. VAT volume reduction was prospectively associated with improvement in RE endoscopic grade dose-dependently. Visceral obesity is a potential target for RE treatment.

Computer-aided diagnosis (CAD) assists endoscopists in analyzing endoscopic images, reducing misdiagnosis rates and enabling timely treatment. A few studies have focused on CAD for gastroesophageal reflux disease, but CAD studies on reflux esophagitis (RE) are still inadequate. This paper presents a CAD study on RE using a dataset collected from hospital, comprising over 3000 images. We propose an uncertainty-aware network with handcrafted features, utilizing representation and classifier decoupling with metric learning to address class imbalance and achieve fine-grained RE classification. To enhance interpretability, the network estimates uncertainty through test time augmentation. The experimental results demonstrate that the proposed network surpasses previous methods, achieving an accuracy of 90.2% and an F1 score of 90.1%.

[Purpose] This study aimed to examine the validity and reproducibility of a new quantitative method for measuring spinal kyphosis using computed tomography (CT), and to investigate its relationship with reflux esophagitis. [Method] Using a new method to measure the index of kyphosis in CT images (IKCT), 10 examiners evaluated 10 cases of spinal kyphosis. One examiner measured 47 cases twice and 20 cases were examined to assess the validity with the kyphosis index. A case-control study was conducted on 303 cases of reflux esophagitis, of which 241 were mild and 62 severe. [Results] Regarding IKCT reproducibility, the inter-rater intraclass correlation coefficient was 0.977. The intra-rater intraclass correlation coefficient was 0.974. The correlation index with the kyphosis index was 0.731. A greater IKCT value, not contracting serious atrophic gastritis, and severe hiatal hernia were identified as risk factors for severe reflux esophagitis. [Conclusion] IKCT is a simple and useful method for measuring kyphosis. The prevention of kyphosis can help suppress severe reflux esophagitis.

BACKGROUND AND AIMS: High prevalence of minimal change lesion (MCL) in nonerosive reflux esophagitis (NERD) patients is commonly recognized by many endoscopists. However, it is difficult to detect MCL with conventional white-light imaging (WLI) endoscopy. Linked color imaging (LCI), a novel image-enhanced endoscopy technology with strong, unique color enhancement, is used for easy recognition of early gastric cancer and detection of Helicobacter pylori infection. The aim of the study was to compare the efficacy of LCI and WLI endoscopy in evaluating MCL in patients with NER. MATERIALS AND METHODS: Forty-one patients with NERD and 38 subjects with nongastroesophageal reflux disease (non-GERD) were recruited in this study between August 2017 and July 2018. During upper gastrointestinal endoscopy, the distal 5 cm of the esophageal mucosal morphology at the squamocolumnar junction was visualized using WLI followed by LCI. MCL was defined as areas of erythema, blurring of the Z-line, friability, decreased vascularity, white turbid discoloration, and edema or accentuation of the mucosal folds. Three experienced endoscopists evaluated the color patterns for MCL on WLI images and on WLI combined with LCI images in both groups. A biopsy was taken 2 cm above the esophagogastric junction. Histologic slides were scored by a pathologist in a blinded manner. RESULTS: The proportion of MCL was higher in the patients with NERD (70.7%, 29/41) than in patients with non-GERD (39.5%, 15/38) using WLI combined with LCI. In 12 patients with NERD, both WLI and LCI showed normal mucosa. The MCL detection rate was significantly higher when using WLI combined with LCI than when using WLI (70.7% vs. 51.2%, P=0.039) in patients with NERD. The histopathologic score of MCL (+) was significantly higher than that of MCL (-) patients in both the NERD group (4.59±0.32 vs. 2.36±0.34, P<0.01) and the non-GERD group (3.47±0.50 vs. 2.00±0.28, P<0.01). The intraobserver reproducibility levels and interobserver agreement were better with LCI than with WLI alone. CONCLUSIONS: Frequency of MCL was higher in patients with NERD than in those with non-GERD. MCL can be identified by using WLI combined with LCI in patients with NERD. By enhancing endoscopic images, LCI is more sensitive in detecting MCL compared with WLI.

ABSTRACT: The similarities and differences between acute esophageal necrosis and severe reflux esophagitis have not been elucidated. We compared Los Angeles classification Grade C reflux esophagitis, Grade D reflux esophagitis, and acute esophageal necrosis to consider the similarities and differences between acute esophageal necrosis and severe reflux esophagitis.We retrospectively reviewed records of patients who underwent esophagogastroduodenoscopy at a tertiary referral center from January 2012 to December 2019. Data on patients diagnosed as Grade C reflux, Grade D reflux, or acute esophageal necrosis for the first time were extracted for analysis.A total of 213 patients were enrolled in the study, composed of 130 Grade C reflux, 74 Grade D reflux, and 9 acute esophageal necrosis patients. Compared to Grade C reflux patients, Grade D reflux and acute esophageal necrosis patients were more likely to be transfused (Pâ=â.013 and Pâ=â.011, respectively), to have duodenal ulcers (Pâ=â.025 and Pâ=â.049, respectively), and to have psychiatric illnesses (Pâ=â.022 and Pâ=â.018, respectively). Compared to both Grade C and D reflux, acute esophageal necrosis patients were more likely to present with shock (Pâ=â.003 and Pâ<â.001, respectively), have type 1 diabetes (Pâ=â.030 and Pâ=â.004, respectively), and present in winter (Pâ<â.001 and Pâ<â.001, respectively). Significant step-wise differences (Grade Câ<âGrade Dâ<âacute esophageal necrosis) were observed in the need for admission (Pâ<â.001 and Pâ=â.009), coffee ground emesis (Pâ<â.001 and Pâ=â.022), and stigmata of hemorrhage on endoscopy (Pâ=â.002 and Pâ<â.001). Admission (Pâ=â.003) and coffee ground emesis (Pâ=â.003) independently predicted either Grade D reflux or acute esophageal necrosis over Grade C reflux on multivariate analysis.Shock, type 1 diabetes, and winter may predict acute esophageal necrosis, while the need for admission and coffee ground emesis may predict Grade D reflux or acute esophageal necrosis.

OBJECTIVES: Diagnosis of reflux esophagitis according to the Los Angeles classification minimal change (LA-M) has a low inter-observer agreement. We aimed to investigate whether the inter-observer agreement of reflux esophagitis was better when expert endoscopists read the endoscopic images, or when the linked color imaging (LCI) or blue laser imaging (BLI)-bright mode was used. In addition, whether the inclusion of LA-M in the definition of reflux esophagitis affected the consistency of the diagnosis was investigated. METHODS: During upper endoscopy, endoscopic images of the gastroesophageal junction were taken using white light imaging (WLI), BLI-bright, and LCI modes. Four expert endoscopists and four trainees reviewed the images to diagnose reflux esophagitis according to the modified LA classification. RESULTS: The kappa values for the inter-observer variability for the diagnosis of reflux esophagitis were poor to fair among the experts (κ = â0.22, 0.17, and 0.27 for WLI, BLI-bright, and LCI, respectively) and poor among the trainees (κ = â0.18, 0.08, and 0.14 for WLI, BLI-bright, and LCI). The inter-observer variabilities for the diagnosis of reflux esophagitis excluding LA-M were fair to moderate (κ = â0.42, 0.35, and 0.42 for WLI, BLI-bright, and LCI) among the expert endoscopists and moderate among the trainees (κ = 0.48, 0.43, and 0.51 for WLI, BLI-bright, and LCI). CONCLUSIONS: The inter-observer agreement for the diagnosis of reflux esophagitis was very low for both the expert endoscopists and the trainees, even using BLI-bright or LCI mode. However, when reflux esophagitis LA-M was excluded from the diagnosis of esophagitis, the degree of inter-observer agreement increased.

BACKGROUND: With more prevalent gastroesophageal reflux disease comes increased cases of Barrett's esophagus and esophageal adenocarcinoma. Image-enhanced endoscopy using linked-color imaging (LCI) differentiates between mucosal colors. We compared LCI, white light imaging (WLI), and blue LASER imaging (BLI) in diagnosing reflux esophagitis (RE). METHODS: Consecutive RE patients (modified Los Angeles [LA] classification system) who underwent esophagogastroduodenoscopy using WLI, LCI, and BLI between April 2017 and March 2019 were selected retrospectively. Ten endoscopists compared WLI with LCI or BLI using 142 images from 142 patients. Visibility changes were scored by endoscopists as follows: 5, improved; 4, somewhat improved; 3, equivalent; 2, somewhat decreased; and 1, decreased. For total scores, 40 points was considered improved visibility, 21-39 points was comparable to white light, and < 20 points equaled decreased visibility. Inter- and intra-rater reliabilities (Intra-class Correlation Coefficient [ICC]) were also evaluated. Images showing color differences (ΔE*) and L* a* b* color values in RE and adjacent esophageal mucosae were assessed using CIELAB, a color space system. RESULTS: The mean age of patients was 67.1 years (range: 27-89; 63 males, 79 females). RE LA grades observed included 52 M, 52 A, 24 B, 11 C, and 3 D. Compared with WLI, all RE cases showed improved visibility: 28.2% (40/142), LA grade M: 19.2% (10/52), LA grade A: 34.6% (18/52), LA grade B: 37.5% (9/24), LA grade C: 27.3% (3/11), and LA grade D: 0% (0/3) in LCI, and for all RE cases: 0% in BLI. LCI was not associated with decreased visibility. The LCI inter-rater reliability was "moderate" for LA grade M and "substantial" for erosive RE. The LCI intra-rater reliability was "moderate-substantial" for trainees and experts. Color differences were WLI: 12.3, LCI: 22.7 in LA grade M; and WLI: 18.2, LCI: 31.9 in erosive RE (P < 0.001 for WLI vs. LCI). CONCLUSION: LCI versus WLI and BLI led to improved visibility for RE after subjective and objective evaluations. Visibility and the ICC for minimal change esophagitis were lower than for erosive RE for LCI. With LCI, RE images contrasting better with the surrounding esophageal mucosa were more clearly viewed.

Objective: While there is an association between successful eradication of Helicobacter pylori (HP) and reflux esophagitis (RE), risk factors associated with RE remain obscure. The aim of this study is to determine risk factors associated with the development of RE after HP eradication.Materials and methods: Among all patients treated with successful HP eradication from 2008 to 2016, we retrospectively analyzed those who were free from RE at initial esophagogastroduodenoscopy (EGD) and who were followed up with EGD after eradication. Patients were classified according to the presence or absence of RE at the follow-up EGD. RE was defined as mucosal breaks proximal to the squamous-columnar junction. Demographic data, underlying diseases, medications and endoscopic findings at the initial EGD were compared between patients with and without RE.Results: Among 1575 patients, 142 (9.0%) had RE at the follow-up EGD. The time interval from HP eradication until EGD ranged from 4 to 24 months. The endoscopic grade of RE was higher in males than in females. Multivariate analysis revealed that male sex (odds ratio [OR], 1.51; 95% confidence interval [CI], 1.04-2.24), body mass index ≥25 kg/m2 (OR, 2.91; 95% CI, 2.00-4.22), use of calcium channel blockers (OR, 1.70; 95% CI, 1.12-2.55), and hiatal hernia (OR, 3.46; 95% CI, 2.41-5.00) were associated with the development of RE.Conclusions: Calcium channel blocker use was found to be a risk factor for the development of RE after eradication of HP.

BACKGROUND: To investigate the efficacy of long-term (52 weeks) maintenance therapy by 10-mg vonoprazan administration for proton pump inhibitor-resistant reflux esophagitis continued from the preceding study. METHODS: Sixteen patients with proton pump inhibitor-resistant reflux esophagitis (mean age 70.9 years, eight males) in whom endoscopic healing was achieved by 20-mg vonoprazan administration for 4 weeks and maintenance of remission was maintained by 10-mg vonoprazan administration for 8 weeks were enrolled. Endoscopy was performed at 52 weeks after the initiation of maintenance therapy with 10-mg vonoprazan to evaluate whether there was any recurrence of reflux esophagitis. Changes in the gastric mucosa were investigated at 52 weeks. Symptoms were assessed using the frequency scale for the symptoms of gastroesophageal reflux disease and the fast gastrin level at 8 and 52 weeks following the maintenance therapy. RESULTS: Endoscopic remission was maintained at 52 weeks in 15 (93.8%) of the 16 patients with proton pump inhibitor-resistant reflux esophagitis. One patient relapsed with grade C of reflux esophagitis. There were no significant differences in the symptom score at 8 and 52 weeks, nor the gastrin level at 8 and 52 weeks. There was no change in the stomach on endoscopy at 52 weeks. CONCLUSION: Long-term maintenance therapy by 10-mg vonoprazan administration is very effective for proton pump inhibitor-resistant reflux esophagitis patients in whom endoscopic healing was maintained by 8 weeks maintenance therapy with 10-mg vonoprazan administration.

BACKGROUND: Esophageal cancer is the eighth most common cancer. The prognosis is bleak in patients with advanced stages. Patients with early disease have a better prognosis than those with advanced stage. There are several techniques for the screening of premalignant and superficial lesions including chromoendoscopy. OBJECTIVE: This article aimed to determine the effectiveness of chromoendoscopy with toluidine blue combined with Lugol's solution for diagnosis of esophageal premalignant and superficial neoplastic lesions in high risk patients. METHODS: Routine white light upper endoscopy was performed. Toluidine blue was sprayed from the gastroesophageal junction to 20 cm of the dental arch. Then the uptake dye areas were characterized. Later Lugol's solution was sprayed. Areas with less-intense staining were characterized. Biopsy of the toluidine blue capturing areas and areas with less-intense staining of Lugol's solution were taken. In the cases where lesions were not evidenced after application of dyes, biopsies four quadrants of the esophageal mucosa were taken. The samples were evaluated by a digestive pathologist. RESULTS: Barrett's esophagus was the most common premalignant lesion and the early neoplastic lesion was adenocarcinoma with a sensitivity of 100%, specificity 85.7%, positive predictive value 30%, negative predictive value 100%, positive likelihood ratio 7 negative likelihood ratio 0. CONCLUSION: Chromoendoscopy with toluidine blue combined with Lugol's solution is a useful tool in the screening of esophageal premalignant lesions and superficial neoplasms.

RESUMO CONTEXTO: O câncer de esôfago é o oitavo câncer mais comum. O prognóstico é sombrio em pacientes com estágios avançados. Pacientes com doença precoce têm um melhor prognóstico do que aqueles com estágio avançado. Existem várias técnicas para a triagem de lesões pré-malignas e superficiais, incluindo cromoendoscopia. OBJETIVO: Este artigo objetivou determinar a efetividade da cromoendoscopia com azul de toluidina combinada com a solução de Lugol para o diagnóstico de lesões neoplásicas pré-malignas e superficiais esofágicas em pacientes de alto risco. MÉTODOS - A endoscopia de luz branca de rotina foi realizada de forma rotineira. O azul do toluidina foi pulverizado desde a junção gastroesofágica até 20 cm da arcada dentária. As áreas impregnadas pela tintura da tomada foram então caracterizadas. Mais adiante a solução de Lugol foi pulverizada. Áreas com coloração menos intensa foram caracterizadas. Foram realizadas biópsias das áreas de captura de azul de toluidina e áreas com coloração menos intensa da solução de Lugol. Nos casos onde as lesões não foram evidenciadas após a aplicação das tinturas, foram feitas biópsias em quatro quadrantes da mucosa esofágica. As amostras foram avaliadas por um patologista especializado. RESULTADOS: O esôfago de Barrett foi a lesão pré-maligna mais frequente e a lesão neoplásica precoce foi adenocarcinoma com sensibilidade de 100%, especificidade de 85,7%, valor preditivo positivo de 30%, valor preditivo negativo 100%, razão de verossimilhança positiva 7 e razão de verossimilhança negativa 0. CONCLUSÃO: A cromoendoscopia com azul de toluidina combinada com a solução de Lugol é uma ferramenta útil na triagem de lesões pré-malignas esofágicas e neoplasias superficiais.

BACKGROUND: Some recent studies suggested that reflux esophagitis is positively correlated with asthma. However, there are debates on this issue. The aim of this study is to clarify the true association between reflux esophagitis and asthma in a large population. METHODS: Medical records of subjects who received health surveillance checkup between January 2005 and December 2011 were reviewed. Their endoscopic findings, medical history, body mass index, and smoking history were analyzed. Erosive esophagitis was defined as endoscopically detected mucosal break at the Z-line, irrespective of reflux symptom. Information about asthma history was obtained from their questionnaires and medical records. RESULTS: Out of the total 15,999 patients, 986 had erosive esophagitis and 376 had asthma. In this population, erosive esophagitis was inversely related with asthma in univariable analysis (OR, 0.586; 95% CI, 0.342-1.003, p = 0.049). In multivariable analysis, asthma was demonstrated as an independent negative risk factor for erosive esophagitis (OR, 0.472; 95% CI, 0.257-0.869, p = 0.016), under adjustment with age (OR, 1.000; 95% CI, 0.994-1.006, p = 0.977), male sex (OR, 2.092; 95% CI, 1.683-2.601, p < 0.001), body mass index (OR, 1.115; 95% CI, 1.090-1.141, p < 0.001), smoking (OR, 1.584; 95% CI, 1.318-1.902, p < 0.001), and urban residence (OR, 1.363; 95% CI, 1.149-1.616, p < 0.001). Likewise, erosive esophagitis was shown to be an independent negative risk factor for asthma (OR, 0.558; 95% CI, 0.324-0.960, p = 0.035) under adjustment with age (OR, 1.025; 95% CI, 1.015-1.034, p <0.001), male sex (OR, 0.861; 95% CI, 0.691-1.074, p = 0.185), and body mass index (OR, 1.067; 95% CI, 1.030-1.106, p < 0.001) in multivariable analysis. CONCLUSIONS: Contrary to previous studies, this large scale data showed inverse association between erosive esophagitis and asthma. Further studies investigating the clear mechanism of this phenomenon are warranted.

PURPOSE: Abdominal ultrasound (US) can visualize the esophagogastric junction (EGJ) as a hyperechoic area in the dorsal portion of the lateral segment of the liver. We prospectively evaluated the EGJ using US elastography (US-EG) in patients with reflux esophagitis (RE) to examine prediction of distal esophageal function. METHODS: Of 108 patients undergoing US-EG and esophagogastroduodenoscopy, 102 in whom the EGJ was observed for ≥ 15 s were included. The subjects were divided into a RE group (n = 41, Grade M/A/B:24/13/4 according to modified Los Angeles Classification) and a non-RE group (n = 61). Direct strain elastography (LOGIQ E9, GE Healthcare), which gives a semi-quantitative elasticity index within a region of interest including the lateral segment, was used as a standard for measurement of the change in stiffness (CS) at the EGJ. RESULTS: The number of CS as determined by US-EG was 6.0 (5.5-6.7) in the RE group and 8.6 (6.6-10.0) in the non-RE group (P < 0.0001). In ROC analysis, the AUC was 0.8415 for diagnosis of RE using the number of CS. At a cut-off of 7.7, the sensitivity, specificity, and accuracy for diagnosis were 92.7, 65.6, and 74.5%, respectively. CONCLUSION: The presence of RE can be predicted based on US-EG.

BACKGROUND: High-resolution manometry (HRM), which is breakthrough testing equipment to evaluate esophageal motor function, was developed in Europe and United State and has garnered attention. Moreover, multichannel intraluminal impedance pH (MII-pH) testing has allowed us to grasp all liquid/gas reflux including not only acid but also non-acid reflux. We examined the impact of the presence of reflux esophagitis (RE) on esophageal motor function before and after laparoscopic fundoplication. MATERIALS AND METHODS: The subjects included 100 patients (male: 63 patients, mean age: 54.1 ± 15.8) among 145 patients who underwent laparoscopic fundoplication for GERD associated diseases during a 4-year period from October 2012 to September 2016, excluding 6 patients who underwent further surgery, 32 patients on whom HRM was not performed, 3 patients who had technical errors during testing, and 4 patients for whom the status of RE was unknown. Regarding HRM, Mano Scan from Given Imaging Ltd. was used, and for the analysis, Mano View version 3.0 from the same company was used, after which data was calculated based on the Chicago Classification advocated by Pandolfino et al. Moreover, for the MII-pH testing, Sleuth manufactured by Sandhill Scientific. Inc. was used and automatic analysis was conducted by a computer. Postoperative assessments were conducted 3 months following surgery for all. Data was described in the median value and inter-quartile range, with a statistically significant difference defined as p < 0.05 by Chi square, Mann-Whitney, and Wilcoxon tests. RESULTS: RE+ group (Los Angeles classification A:B:C:D = 7:9:16:12 patients) included 44 patients (44%), of older age compared to the RE- group (62 vs. 50 years, p = 0.012) and a higher Body Mass Index value (24.0 vs. 22.5, p = 0.045); however, no differences were observed in terms of gender and duration of symptoms. In the preoperative findings on MII-pH, the RE+ group demonstrated significantly longer acid reflux time (4.7 vs. 1.3%, p = 0.005), while in the HRM findings, the RE- group demonstrated a significantly longer abdominal esophagus (0 vs. 0.4 cm, p = 0.049) and maintained esophageal body motor function (DCI: 1054 vs. 1407 mmHg s cm, p = 0.021, Intact peristalsis ratio: 90 vs. 100%, p = 0.037). As to the comparison of the treatment effect before and after laparoscopic fundoplication (Toupet fundoplication for all), significant improvements were observed in both groups in various parameters regarding reflux including acid reflux time, total number of liquid reflux episodes and total number of reflux episodes. Moreover, for both groups, the total length of the lower esophageal sphincter (LES) (RE+ group: 2.7 vs. 3.2 cm, p = 0.001, RE- group: 3.0 vs. 3.4 cm, p = 0.003) and the total length of the abdominal esophagus (RE+ group: 0 vs. 1.6 cm, p < 0.001, RE- group: 0 vs. 1.8 cm, p = 0.001) were significantly extended following surgery; however, no change was observed in DCI before and after surgery. CONCLUSIONS: Regardless of the presence of RE, cardiac function and LES function were improved following laparoscopic Toupet fundoplication, but no changes were observed in esophageal body motor function.

AIM: To compare vonoprazan 10 and 20 mg vs lansoprazole 15 mg as maintenance therapy in healed erosive esophagitis (EE). METHODS: A total of 607 patients aged ≥ 20 years, with endoscopically-confirmed healed EE following 8 wk of treatment with vonoprazan 20 mg once daily, were randomized 1:1:1 to receive lansoprazole 15 mg (n = 201), vonoprazan 10 mg (n = 202), or vonoprazan 20 mg (n = 204), once daily. The primary endpoint of the study was the rate of endoscopically-confirmed EE recurrence during a 24-wk maintenance period. The secondary endpoint was the EE recurrence rate at Week 12 during maintenance treatment. Additional efficacy endpoints included the incidence of heartburn and acid reflux, and the EE healing rate 4 wk after the initiation of maintenance treatment. Safety endpoints comprised adverse events (AEs), vital signs, electrocardiogram findings, clinical laboratory results, serum gastrin and pepsinogenâI/II levels, and gastric mucosa histopathology results. RESULTS: Rates of EE recurrence during the 24-wk maintenance period were 16.8%, 5.1%, and 2.0% with lansoprazole 15 mg, vonoprazan 10 mg, and vonoprazan 20 mg, respectively. Vonoprazan was shown to be non-inferior to lansoprazole 15 mg (P < 0.0001 for both doses). In a post-hoc analysis, EE recurrence at Week 24 was significantly reduced with vonoprazan at both the 10 mg and the 20 mg dose vs lansoprazole 15 mg (5.1% vs 16.8%, P = 0.0002, and 2.0% vs 16.8%, P < 0.0001, respectively); by contrast, the EE recurrence rate did not differ significantly between the two doses of vonoprazan (P = 0.1090). The safety profiles of vonoprazan 10 and 20 mg were similar to that of lansoprazole 15 mg in patients with healed EE. Treatment-related AEs were reported in 11.4%, 10.4%, and 10.3% of patients in the lansoprazole 15 mg, vonoprazan 10 mg, and vonoprazan 20 mg arms, respectively. CONCLUSION: Our findings confirm the non-inferiority of vonoprazan 10 and 20 mg to lansoprazole 15 mg as maintenance therapy for patients with healed EE.

Here we report a retrospective cross-sectional study on Esophageal eosinophilia (EsEo) frequency in Brazil, for 2, 425 pediatric patients with symptoms associated with gastroesophageal diseases in 2012. EsEo is defined by ≥15 eosinophils per high power field (400x) and confirmed through histological analyses of esophageal biopsies. Overall, 126 patients had EsEo equating to a frequency of 5.2%. There was a significant difference between the endoscopic features of patients with EsEo, where 10.7% had erosive esophagitis, 3.0% had non-erosive esophagitis and 1% showed normal esophageal mucosa. According to the interaction of the variables in the Classification and Regression Tree Analysis, most patients diagnosed with EsEo were older males with erosive esophagitis. On the other hand, the lowest frequency of EsEo was found among younger females with non-erosive esophagitis/normal mucosa. Environmental conditions, including climate variation and changes, were observed in association with EsEo, supporting a potential role for environmental factors in its pathogenesis. There was an inverse correlation between the number of EsEo, rainfall and humidity. EsEo is a relatively frequent finding in the pediatric population of Brazil with symptoms of gastroesophageal diseases. Both clinical and histological examinations of patients are important for a reliable diagnostic of EsEo cases and to patient care.

RESUMEN: El reflujo faringolaríngeo. Se origina por el flujo retrógrado de contenido gástrico hacia la faringe, pero existen factores, capaces de perpetuarlo: disfunción del esfínter esofágico, tiempo de exposición y sensibilidad del tejido al material refluido, estos elementos permiten considerar al reflujo faringolaríngeo como una entidad diferente del reflujo gastroesofágico. OBJETIVO: Encontrar una correlación entre los signos endoscópicos de pacientes con síntomas por reflujo gastroesofágico y reflujo faringolaringeo a través de los hallazgos de la fibrolaringoscopía flexible y video endoscopia digestiva alta. Además de identificar la distribución epidemiológica de los pacientes participantes. MATERIAL Y MÉTODOS: Estudio observacional, retrospectivo y analítico. Se incluyeron pacientes que consultaron al servicio de Otorrinolaringología y Gastroenterología de la Clínica Universitaria Reina Fabiola Córdoba Argentina, por sintomatología de reflujo faringolaríngeo y gastroesofágico. Entre mayo/2016 y mayo/2017. Los hallazgos de reflujo faringolaríngeo por fibrolaringoscopía flexible y de esofagitis por video endoscopia digestiva alta de cada paciente se compararon con la prueba de Chi cuadrado. Se consideró significativo un valor de p ≤0.05. RESULTADOS: Se incluyeron 49 pacientes entre 7 y 80 años; de éstos, el 45% son de género masculino, y 55% femenino. El 100% de los pacientes presentaron criterios fibrolaringoscópicos diagnósticos de reflujo faringolaríngeo, por el contrario, la video endoscopia digestiva alta mostró que solo el 55% de los pacientes tenían signos de esofagitis (p= 0.24). CONCLUSIONES: En este estudio, no se observó una correlación diagnóstica entre los signos de la fibrolaringoscopía y video endoscopia digestiva alta en relación al diagnóstico de reflujo faringolaríngeo y esofagitis. No se encontró una diferencia entre ambos géneros y los signos de reflujo faringolaríngeo y esofagitis. La frecuencia de las manifestaciones otorrinolaringológicas del reflujo faringolaríngeo se relaciona directamente con el incremento de la edad; sobre todo, la cuarta década de la vida. (AU)
OBJECTIVE: Find a correlation between the endoscopic signs of patients with symptoms due to gastroesophagic reflux and faringolaryngeal reflux through the findings of fiber-optic laryngoscopy and upper gastrointestinal endoscopy. In addition, identify the epidemiological distribution of the participant's patients. MATERIALS AND METHODS: Observational, retrospective and analytical study of patients who have consulted the service of Otorhinolaryngology and Gastroenterology of the Reina Fabiola University Clinic, due to symptomatology of pharyngolaryngeal reflux and gastroesophageal reflux. Between May/2016 and May/2017. The findings of pharyngolaryngeal reflux by fiber-optic laryngoscopy and esophagitis by upper gastrointestinal endoscopy of each patient were compared with the Chi square test. A value of p ≤0.05 was considered significant. RESULTS: We included 49 patients between 7 and 80 years old; 45% of them were male and 55% were female. 100% of the patients had fiber-optic laryngoscopy diagnostic criteria of pharyngolaryngeal reflux. In contrast, upper digestive endoscopy showed that only 55% of the patients had signs of esophagitis (p = 0.24). CONCLUSIONS: In this study, wasn´t observed a diagnostic correlation between the signs of fiber-optic laryngoscopy and upper gastrointestinal endoscopy in relation to the diagnosis of pharyngolaryngeal reflux and esophagitis. We did not find a difference between both genders and signs of esophageal pharyngolaryngeal reflux. The frequency of otorhinolaryngological manifestations of pharyngolaryngeal reflux is directly related to the increase in age. (AU)

INTRODUCTION: The relationship between the Los Angeles (LA) grade of esophagitis and acid exposure by pH monitoring is unclear. The aim of this study was to correlate the results of pH testing in patients with esophagitis to determine at what LA grade of esophagitis a pH test is not necessary. METHODS: A retrospective review was performed of the records of all patients who underwent upper endoscopy and were found to have esophagitis graded using the LA system and who had pH monitoring from 2014 to 2016. An abnormal pH test was determined based on the DeMeester score. RESULTS: There were 56 patients with a median age of 57 years. Esophagitis was LA grade A in 19, B in 20, C in 15 and D in 2 patients. An abnormal pH score was present in 47 patients (84%). All patients with C or D esophagitis had an abnormal pH score compared to 79% and 75% of patients with A and B esophagitis, respectively. CONCLUSIONS: The presence of LA C or D esophagitis was always associated with increased esophageal acid exposure on pH testing and is proof of reflux disease. However, pH testing is recommended prior to antireflux surgery in patients with LA A or B esophagitis.

BACKGROUND: Rabeprazole at 10 or 20 mg twice daily (b.i.d.) has been reported to be highly effective in the treatment of proton pump inhibitor (PPI)-resistant reflux esophagitis (RE) that is refractory to the standard once-daily PPI regimen. We evaluated the efficacy and safety of rabeprazole maintenance therapy at 10 mg once daily (q.d.) or b.i.d. for longer than 8 weeks. METHODS: Patients with RE refractory to standard PPI regimens for at least 8 weeks were enrolled. They were treated with rabeprazole at 10 or 20 mg b.i.d. for 8 weeks during the open-label treatment period. After endoscopic examination, those with confirmed healing entered the subsequent double-blind maintenance therapy. During this period, the subjects were randomized to receive rabeprazole 10 mg q.d. (control) or 10 mg b.i.d. The primary endpoint was the endoscopic no-recurrence rate at Week 52. RESULTS: In total, 517 subjects entered the treatment, and 359 subjects continued on maintenance therapy. The full analysis set for central assessment included 343 subjects. The no-recurrence rate at Week 52 was significantly higher in the b.i.d. group (73.9%; p < 0.001, χ2 test) than in the q.d. group (44.8%). In particular, the b.i.d. regimen was more effective in all subgroups with Los Angeles Classification Grade B to D at treatment entry. CONCLUSIONS: In the maintenance treatment of PPI-resistant RE, rabeprazole at 10 mg b.i.d. exerted a stronger recurrence-preventing effect than 10 mg q.d. over 52 weeks. No particular safety issues were noted during long-term administration. ClinicalTrials.gov number: NCT02135107.

BACKGROUND: Reflux esophagitis (RE) may mimic symptoms requiring cross-sectional imaging. METHODS: From 565 patients who had CT and esophagogastroduodenoscopy within four days apart, CT scans of 72 patients with RE confirmed by esophagogastroduodenoscopy and 108 matched patients without RE were evaluated for distal esophageal wall characteristics. RESULTS: In RE patients the distal esophageal wall thickness was greater (5.2±2.0mm) compared to patients without RE (3.5±1.2mm, p<0.0001) with AUC of 0.78 and 56% sensitivity, 88% specificity for a 5.0mm cut-off. CONCLUSIONS: There is a moderate association between distal esophageal wall thickness on CT and RE diagnosed by esophagogastroduodenoscopy as the reference standard.
