RESUMO
OBJECTIVE: To comprehensively evaluate the efficacy, safety, patient symptoms, and quality-of-life (QoL) of lubiprostone, linaclotide, and elobixibat as treatment for chronic constipation (CC). DESIGN: Systematic literature review (SLR) and meta-analysis (MA). Literature searches were conducted on PubMed and Embase using the Ovid platform. METHODS: SLR including randomized controlled trials (RCTs) and observational studies was conducted to identify the overall efficacy and safety of lubiprostone, linaclotide, and elobixibat. Thereafter, MA was performed using only RCTs. The number needed to treat (NNT) and number needed to harm (NNH) analyses were additionally conducted. PRIMARY AND SECONDARY OUTCOME MEASURES: The primary outcome was efficacy regarding change in spontaneous bowel movements. Secondary outcomes included safety, constipation-related symptoms, and QoL. RESULTS: Twenty-four studies met the inclusion criteria for the SLR: 17 RCTs, 4 observational studies, and 3 single-arm trials. Feasibility assessment for the MA resulted in 14 studies available for safety data analysis, and 8 available for efficacy analysis, respectively. Three drugs showed similar efficacy in the MA and NNT analysis. However, the NNH analysis revealed distinct safety profiles: lubiprostone, linaclotide, and elobixibat were linked to the highest risk of nausea, diarrhea, and abdominal pain, respectively. CONCLUSION: The current study provides an updated overview of the efficacy, safety, patient symptoms, and QoL of the three drugs with different mechanisms of action for CC treatment.The findings could help physicians adopt an individualized approach for treating patients with CC in clinical practice.

INTRODUCTION: This study evaluated the psychometric properties of the newly developed chronic constipation-therapeutic efficacy and satisfaction test (CC-TEST) among patients with chronic constipation. METHODS: Japanese patients with moderate or severe chronic constipation underwent a 4-week remedy. The baseline, 2-week, and 4-week assessments included the CC-TEST, Constipation Scoring System (CSS), Medical Outcome Study Short Form-8 Health Survey (SF-8), and Hospital Anxiety and Depression Scale (HADS). The CC-TEST comprises three domains: (1) symptoms; chronic constipation symptom severity (seven items), defecation status (five items), (2) impact for daily life; dissatisfaction with daily life level (DS; four items), and (3) therapeutic response; therapeutic efficacy measured by patients and medication compliance (four items). RESULTS: Of 201 eligible patients at baseline, 110 completed the 4-week treatment and the survey responses. Cronbach's α values for the stool, defecation, and abdominal symptom subscales, as well as the total symptom score and DS subscale, showed good internal consistency reliability (0.72-0.80). Pearson's r for comparisons between corresponding items (CC-TEST symptoms with CSS, and CC-TEST DS with SF-8 physical and mental component summary scores) was significant. After 4 weeks, scores for symptoms, defecation status, and DS items/subscales notably decreased, with a significant effect size (p < 0.005, Cohen's d; 0.30-1.16). Statistically significant differences emerged between treatment responders and nonresponders using the three responder definitions, in changes in scores for most CC-TEST symptoms, defecation status, and DS items/subscales (p < 0.05). CONCLUSION: CC-TEST demonstrates commendable reliability, convergent and known-group validity, and responsiveness to treatment effects. As a simple, comprehensive, and versatile patient-reported outcome measure, CC-TEST may be well suited for clinical trials and primary care of Japanese patients with chronic constipation.
RESUMO
In July 2023 the Japan Gastroenterological Association published the first version of its clinical guidelines for chronic constipation 2023. Based on the latest evidence, these guidelines describe the definition, classification, diagnostic criteria, diagnostic testing methods, epidemiology, pathophysiology, and treatment of chronic constipation. They include flowcharts for both diagnosis and treatment of chronic constipation. In the treatment of chronic constipation, the first step involves differentiating between secondary forms, such as organic disease-associated constipation, systemic disease-associated constipation, and drug-induced constipation. The next step is to determine whether the chronic constipation stems from a motility disorder, a form of primary chronic constipation. For functional constipation and constipation-predominant irritable bowel syndrome, treatment should be initiated after evaluating symptoms like reduced frequency of bowel movement frequency type or defecation difficulty type. The first line of treatment includes improvement of lifestyle habits and diet therapy. The first drugs to consider for oral treatment are osmotic laxatives. If these are ineffective, secretagogues and ileal bile acid transporter inhibitors are candidates. However, stimulant laxatives are exclusively designated for as-needed use. Probiotics, bulk-forming laxatives, prokinetics, and Kampo medicine, for which there is insufficient evidence, are considered alternative or complementary therapy. Providing the best clinical strategies for chronic constipation therapy in Japan, these clinical guidelines for chronic constipation 2023 should prove useful for its treatment worldwide.
RESUMO
A 30-year-old man with idiopathic peptic ulcer disease (IPUD) experienced repeated recurrence of ulcerative bleeding despite treatment with lansoprazole and then vonoprazan. Further evaluation suggested that the cause of the ulcer was strong contractile movements of the antrum. This prompted the co-administration of trimebutine maleate (TM) and vonoprazan to relieve the stomach contractions. TM was effective in preventing the recurrence of ulcerative bleeding, and the patient has remained in remission for 4 years. This case highlights the potential efficacy of TM in treating IPUD and the importance of considering hypercontractility as the underlying cause in cases of IPUD.

In Japan, standard of care of the patients with resectable esophageal cancer is neoadjuvant chemotherapy (NAC) followed by esophagectomy. Patients unfitted for surgery or with unresectable locally advanced esophageal cancer are generally indicated with definitive chemoradiotherapy (CRT). Local disease control is undoubtful important for the management of patients with esophageal cancer, therefore endoscopic evaluation of local efficacy after non-surgical treatments must be essential. The significant shrink of primary site after NAC has been reported as a good indicator of pathological good response as well as favorable survival outcome after esophagectomy. And patients who could achieve remarkable shrink to T1 level after CRT had favorable outcomes with salvage surgery and could be good candidates for salvage endoscopic treatments. Based on these data, "Japanese Classification of Esophageal Cancer, 12th edition" defined the new endoscopic criteria "remarkable response (RR)", that means significant volume reduction after treatment, with the subjective endoscopic evaluation are proposed. In addition, the finding of local recurrence (LR) at primary site after achieving a CR was also proposed in the latest edition of Japanese Classification of Esophageal Cancer. The findings of LR are also important for detecting candidates for salvage endoscopic treatments at an early timing during surveillance after CRT. The endoscopic evaluation would encourage us to make concrete decisions for further treatment indications, therefore physicians treating patients with esophageal cancer should be well-acquainted with each finding.

BACKGROUND & AIMS: Currently, large, nationwide, long-term follow-up data on acute lower gastrointestinal bleeding (ALGIB) are scarce. We investigated long-term risks of recurrence after hospital discharge for ALGIB using a large multicenter dataset. METHODS: We retrospectively analyzed 5048 patients who were urgently hospitalized for ALGIB at 49 hospitals across Japan (CODE BLUE-J study). Risk factors for the long-term recurrence of ALGIB were analyzed by using competing risk analysis, treating death without rebleeding as a competing risk. RESULTS: Rebleeding occurred in 1304 patients (25.8%) during a mean follow-up period of 31 months. The cumulative incidences of rebleeding at 1 and 5 years were 15.1% and 25.1%, respectively. The mortality risk was significantly higher in patients with out-of-hospital rebleeding episodes than in those without (hazard ratio, 1.42). Of the 30 factors, multivariate analysis showed that shock index ≥1 (subdistribution hazard ratio [SHR], 1.25), blood transfusion (SHR, 1.26), in-hospital rebleeding (SHR, 1.26), colonic diverticular bleeding (SHR, 2.38), and thienopyridine use (SHR, 1.24) were significantly associated with increased rebleeding risk. Multivariate analysis of colonic diverticular bleeding patients showed that blood transfusion (SHR, 1.20), in-hospital rebleeding (SHR, 1.30), and thienopyridine use (SHR, 1.32) were significantly associated with increased rebleeding risk, whereas endoscopic hemostasis (SHR, 0.83) significantly decreased the risk. CONCLUSIONS: These large, nationwide follow-up data highlighted the importance of endoscopic diagnosis and treatment during hospitalization and the assessment of the need for ongoing thienopyridine use to reduce the risk of out-of-hospital rebleeding. This information also aids in the identification of patients at high risk of rebleeding.

BACKGROUND AND AIMS: We aimed to determine the optimal timing of colonoscopy and factors that benefit patients who undergo early colonoscopy for acute lower GI bleeding. METHODS: We identified 10,342 patients with acute hematochezia (CODE BLUE-J study) admitted to 49 hospitals in Japan. Of these, 6270 patients who underwent a colonoscopy within 120 hours were included in this study. The inverse probability of treatment weighting method was used to adjust for baseline characteristics among early (≤24 hours, n = 4133), elective (24-48 hours, n = 1137), and late (48-120 hours, n = 1000) colonoscopy. The average treatment effect was evaluated for outcomes. The primary outcome was 30-day rebleeding rate. RESULTS: The early group had a significantly higher rate of stigmata of recent hemorrhage (SRH) identification and a shorter length of stay than the elective and late groups. However, the 30-day rebleeding rate was significantly higher in the early group than in the elective and late groups. Interventional radiology (IVR) or surgery requirement and 30-day mortality did not significantly differ among groups. The interaction with heterogeneity of effects was observed between early and late colonoscopy and shock index (shock index <1, odds ratio [OR], 2.097; shock index ≥1, OR, 1.095; P for interaction = .038) and performance status (0-2, OR, 2.481; ≥3, OR, .458; P for interaction = .022) for 30-day rebleeding. Early colonoscopy had a significantly lower IVR or surgery requirement in the shock index ≥1 cohort (OR, .267; 95% confidence interval, .099-.721) compared with late colonoscopy. CONCLUSIONS: Early colonoscopy increased the rate of SRH identification and shortened the length of stay but involved an increased risk of rebleeding and did not improve mortality and IVR or surgery requirement. Early colonoscopy particularly benefited patients with a shock index ≥1 or performance status ≥3 at presentation.

BACKGROUND AND AIMS: Ligation therapy, including endoscopic detachable snare ligation (EDSL) and endoscopic band ligation (EBL), has emerged as an endoscopic treatment for colonic diverticular bleeding (CDB); its comparative effectiveness and risk of recurrent bleeding remain unclear, however. Our goal was to compare the outcomes of EDSL and EBL in treating CDB and identify risk factors for recurrent bleeding after ligation therapy. METHODS: We reviewed data of 518 patients with CDB who underwent EDSL (n = 77) or EBL (n = 441) in a multicenter cohort study named the Colonic Diverticular Bleeding Leaders Update Evidence From Multicenter Japanese Study (CODE BLUE-J Study). Outcomes were compared by using propensity score matching. Logistic and Cox regression analyses were performed for recurrent bleeding risk, and a competing risk analysis was used to treat death without recurrent bleeding as a competing risk. RESULTS: No significant differences were found between the 2 groups in terms of initial hemostasis, 30-day recurrent bleeding, interventional radiology or surgery requirements, 30-day mortality, blood transfusion volume, length of hospital stay, and adverse events. Sigmoid colon involvement was an independent risk factor for 30-day recurrent bleeding (odds ratio, 1.87; 95% confidence interval, 1.02-3.40; P = .042). History of acute lower GI bleeding (ALGIB) was a significant long-term recurrent bleeding risk factor on Cox regression analysis. A performance status score of 3/4 and history of ALGIB were long-term recurrent bleeding factors on competing risk regression analysis. CONCLUSIONS: There were no significant differences in outcomes between EDSL and EBL for CDB. After ligation therapy, careful follow-up is required, especially in the treatment of sigmoid diverticular bleeding during admission. History of ALGIB and performance status at admission are important risk factors for long-term recurrent bleeding after discharge.

INTRODUCTION: Weekend admissions showed increased mortality in several medical conditions. This study aimed to examine the weekend effect on acute lower gastrointestinal bleeding (ALGIB) and its mortality and other outcomes. METHODS: This retrospective cohort study (CODE BLUE-J Study) was conducted at 49 Japanese hospitals between January 2010 and December 2019. In total, 8,120 outpatients with acute hematochezia were enrolled and divided into weekend admissions and weekday admissions groups. Multiple imputation (MI) was used to handle missing values, followed by propensity score matching (PSM) to compare outcomes. The primary outcome was mortality; the secondary outcomes were rebleeding, length of stay (LOS), blood transfusion, thromboembolism, endoscopic treatment, the need for interventional radiology, and the need for surgery. Colonoscopy and computed tomography (CT) management were also evaluated. RESULTS: Before PSM, there was no significant difference in mortality (1.3% vs. 0.9%, p = 0.133) between weekend and weekday admissions. After PSM with MI, 1,976 cases were matched for each admission. Mortality was not significantly different for weekend admissions compared with weekday admissions (odds ratio [OR] 1.437, 95% confidence interval [CI] 0.785-2.630; p = 0.340). No significant difference was found with other secondary outcomes in weekend admissions except for blood transfusion (OR 1.239, 95% CI 1.084-1.417; p = 0.006). Weekend admission had a negative effect on early colonoscopy (OR 0.536, 95% CI 0.471-0.609; p < 0.001). Meanwhile, urgent CT remained significantly higher in weekend admissions (OR 1.466, 95% CI 1.295-1.660; p < 0.001). CONCLUSION: Weekend admissions decrease early colonoscopy and increase urgent CT but do not affect mortality or other outcomes except transfusion.

BACKGROUND AND AIM: The clinical severity and course of acute lower gastrointestinal bleeding (ALGIB) are believed to differ between inpatient-onset and outpatient-onset cases, but no reports have investigated these issues in detail. We aimed to evaluate the clinical differences between inpatient-onset and outpatient-onset ALGIB. METHODS: Medical records of patients who had undergone emergency colonoscopy for ALGIB were retrospectively reviewed. The severity was evaluated using the NOBLADS score. Patients with obvious ALGIB relapse and/or persistent iron-deficiency anemia after emergency colonoscopy were considered to exhibit a poor clinical course. RESULTS: We reviewed 723 patients with ALGIB and divided them into the inpatient-onset cohort (172 patients) and outpatient-onset cohort (551 patients). Compared with the outpatient-onset cohort, the inpatient-onset cohort had a significantly higher proportion of patients with a poor clinical course (51.2% vs 21.6%; P < 0.001) and a significantly higher mean NOBLADS score (3.6 ± 1.1 vs 2.5 ± 1.0; P < 0.001). The most common bleeding source was acute hemorrhagic rectal ulcer (52.3%) in the inpatient-onset cohort and colonic diverticular bleeding (29.4%) in the outpatient-onset cohort. Multivariate analysis showed that a platelet count < 15 × 104 /µL and albumin concentration < 3 g/dL were significantly associated with a poor clinical course in the inpatient-onset cohort. CONCLUSIONS: The clinical course was significantly worse in the inpatient-onset cohort than in the outpatient-onset cohort. The bleeding source, clinical characteristics, and clinical course differed between the inpatient-onset and outpatient-onset cohorts. The clinical course in the inpatient-onset cohort may depend on the patient's condition at ALGIB onset.

AIM: No studies have compared the clinical outcomes of early and delayed feeding in patients with acute lower gastrointestinal bleeding (ALGIB). This study aimed to evaluate the benefits and risks of early feeding in a nationwide cohort of patients with ALGIB in whom haemostasis was achieved. METHODS: We reviewed data for 5910 patients with ALGIB in whom haemostasis was achieved and feeding was resumed within 3 days after colonoscopy at 49 hospitals across Japan (CODE BLUE-J Study). Patients were divided into an early feeding group (≤1 day, n = 3324) and a delayed feeding group (2-3 days, n = 2586). Clinical outcomes were compared between the groups by propensity matching analysis of 1508 pairs. RESULTS: There was no significant difference between the early and delayed feeding groups in the rebleeding rate within 7 days after colonoscopy (9.4% vs. 8.0%; p = 0.196) or in the rebleeding rate within 30 days (11.4% vs. 11.5%; p = 0.909). There was also no significant between-group difference in the need for interventional radiology or surgery or in mortality. However, the median length of hospital stay after colonoscopy was significantly shorter in the early feeding group (5 vs. 7 days; p < 0.001). These results were unchanged when subgroups of presumptive and definitive colonic diverticular bleeding were compared. CONCLUSION: The findings of this nationwide study suggest that early feeding after haemostasis can shorten the hospital stay in patients with ALGIB without increasing the risk of rebleeding.

INTRODUCTION: Length of stay (LOS) in hospital affects cost, patient quality of life, and hospital management; however, existing gastrointestinal bleeding models applicable at hospital admission have not focused on LOS. We aimed to construct a predictive model for LOS in acute lower gastrointestinal bleeding (ALGIB). METHODS: We retrospectively analyzed the records of 8,547 patients emergently hospitalized for ALGIB at 49 hospitals (the CODE BLUE-J Study). A predictive model for prolonged hospital stay was developed using the baseline characteristics of 7,107 patients and externally validated in 1,440 patients. Furthermore, a multivariate analysis assessed the impact of additional variables during hospitalization on LOS. RESULTS: Focusing on baseline characteristics, a predictive model for prolonged hospital stay was developed, the LONG-HOSP score, which consisted of low body mass index, laboratory data, old age, nondrinker status, nonsteroidal anti-inflammatory drug use, facility with ≥800 beds, heart rate, oral antithrombotic agent use, symptoms, systolic blood pressure, performance status, and past medical history. The score showed relatively high performance in predicting prolonged hospital stay and high hospitalization costs (area under the curve: 0.70 and 0.73 for derivation, respectively, and 0.66 and 0.71 for external validation, respectively). Next, we focused on in-hospital management. Diagnosis of colitis or colorectal cancer, rebleeding, and the need for blood transfusion, interventional radiology, and surgery prolonged LOS, regardless of the LONG-HOSP score. By contrast, early colonoscopy and endoscopic treatment shortened LOS. CONCLUSIONS: At hospital admission for ALGIB, our novel predictive model stratified patients by their risk of prolonged hospital stay. During hospitalization, early colonoscopy and endoscopic treatment shortened LOS.

Melanosis coli (MC) is an acquired colorectal disorder visualized as colonic mucosa pigmentation. Disease severity is confirmed based on MC depth, shape, and coloration, although the clinical course is not fully understood. This study sought to clarify characteristics of MC development and disappearance and to investigate its clinical course and severity. Contributors to MC grade progression were explored. This study reviewed MC cases discovered via colonoscopy at a single institution over a 10-year period. Of all 216 MC cases, 17 developing and 10 disappearing cases were detected. Anthranoid laxative use was a key factor: 29.4% of the developing cases had used such agents before the initial MC diagnosis, whereas 40% of disappearing cases had discontinued anthranoids prior to detection of MC disappearance. Among 70 grade I cases, progression to grade II occurred in 16 cases during a mean follow-up of 3.67±2.1 years (rate of progression=22.8%). Males more commonly showed progressive than stable grade I cases, and the probability of progression was higher for male than for female cases. An association between anthranoid administration and MC presence was presumed, and grade I MC was found to progress in severity over 5 years.

BACKGROUND: Although anxiety and depression status is considered related to gastroesophageal reflux disease (GERD) and functional dyspepsia (FD) symptoms, ambiguity primarily arises from the difficulty in determining their cause-effect relationships. We aimed to examine the longitudinal reciprocal causation between anxiety/depression status and GERD/FD symptoms among symptomatic adult patients with GERD. METHODS: Adult (≥ 20 years) patients with GERD symptoms received PPI treatment for 4 weeks after endoscopy. GERD and FD symptom subscales (GERD-SS/FD-SS) were evaluated using the gastroesophageal reflux and dyspepsia therapeutic efficacy and satisfaction test (GERD-TEST). Anxiety and depression status were evaluated using the hospital anxiety and depression scale (HADS). A cross-lagged analysis using structural equation modeling was conducted to examine causal relationships among psychiatric bias (anxiety and depression scores) and upper gastrointestinal symptoms (GERD-SS and FD-SS scores) over time. RESULTS: A total of 182 patients with GERD (men: 120; age: 57.1 ± 12.8 years; body mass index: 24.2 ± 4.1 kg/m2; nonerosive reflux disease/erosive reflux disease: 61/121) were eligible before (T1) and after 4 weeks (T2) of PPI therapy. The cross-lagged effect model indicated that anxiety at T1 contributed to the FD-SS at T2 (ß = 0.18*) and depression at T1 contributed to the GERD-SS at T2 (ß = 0.23*) (*p < 0.05). CONCLUSION: Psychiatric bias was a risk factor for refractory GERD and FD. Anxiety and depression status reduced the therapeutic effect of PPIs on GERD and FD symptoms. Therefore, attention is required to detect the anxiety/depression status of patients with GERD/FD symptoms to treat patients appropriately and optimize therapeutic outcomes.

BACKGROUND AND AIMS: Treatment strategies for colonic diverticular bleeding (CDB) based on stigmata of recent hemorrhage (SRH) remain unstandardized, and no large studies have evaluated their effectiveness. We sought to identify the best strategy among combinations of SRH identification and endoscopic treatment strategies. METHODS: We retrospectively analyzed 5823 CDB patients who underwent colonoscopy at 49 hospitals throughout Japan (CODE-BLUE J-Study). Three strategies were compared: find SRH (definitive CDB) and treat endoscopically, find SRH (definitive CDB) and treat conservatively, and without finding SRH (presumptive CDB) treat conservatively. In conducting pairwise comparisons of outcomes in these groups, we used propensity score-matching analysis to balance baseline characteristics between the groups being compared. RESULTS: Both early and late recurrent bleeding rates were significantly lower in patients with definitive CDB treated endoscopically than in those with presumptive CDB treated conservatively (<30 days, 19.6% vs 26.0% [P < .001]; <365 days, 33.7% vs 41.6% [P < .001], respectively). In patients with definitive CDB, the early recurrent bleeding rate was significantly lower in those treated endoscopically than in those treated conservatively (17.4% vs 26.7% [P = .038] for a single test of hypothesis; however, correction for multiple testing of data removed this significance). The late recurrent bleeding rate was also lower, but not significantly, in those treated endoscopically (32.0% vs 36.1%, P = .426). Definitive CDB treated endoscopically showed significantly lower early and late recurrent bleeding rates than when treated conservatively in cases of SRH with active bleeding, nonactive bleeding, and in the right-sided colon but not left-sided colon. CONCLUSIONS: Treating definitive CDB endoscopically was most effective in reducing recurrent bleeding over the short and long term, compared with not treating definitive CDB or presumptive CDB. Physicians should endeavor to find and treat SRH for suspected CDB.

OBJECTIVES: The Kyoto classification of gastritis was established for diagnosing Helicobacter pylori (H. pylori) infection via endoscopic findings. We investigated the role of the Kyoto classification of gastritis in the diagnosis of H. pylori infection and histological gastritis in Japanese individuals. Moreover, the histological findings of gastritis in H. pylori infection were examined based on age and sex differences. METHODS: We selected 561 patients aged 20-79 years who underwent gastroduodenal endoscopy at our hospital between 2010 and 2018. Endoscopic biopsy specimens from the antrum and corpus were used to investigate H. pylori infection and histology. Endoscopic findings were based on the Kyoto classification of gastritis, and histological findings were based on the updated Sydney System. RESULTS: Endoscopic findings based on the Kyoto classification of gastritis (H. pylori positive, 303 patients; H. pylori negative, 258 patients, based on endoscopic findings) had 98.7% sensitivity and 98.4% specificity for histological gastritis. In addition, endoscopic findings in the three age groups (20-39, 40-59, and 60-79 years) had high sensitivity and specificity. Atrophy and intestinal metaplasia were found only in the H. pylori-positive group and progressed with age. Histological inflammation of pyloric mucosa in the younger age group of H. pylori-positive patients was significantly higher than that in the elderly group. Significant inflammation was observed in young women. CONCLUSIONS: The Kyoto classification of gastritis can not only diagnose H. pylori infection but also detect histological gastritis. Histological gastritis has varying characteristics of inflammation, atrophy, and intestinal metaplasia, depending on age and sex.

BACKGROUND: To date, no in-depth studies have focused on the impact of various clinical characteristics of esophageal squamous cell carcinoma (ESCC), including its association with subjective symptoms, on patient prognosis. We aimed to investigate the clinical factors that affect the prognosis of patients with ESCC and to clarify how subjective symptoms are related to prognosis. METHODS: We retrospectively evaluated the clinical records of 503 consecutive patients with ESCC from April 2011 to December 2019. Six established prognostic factors for ESCC (body mass index, alcohol drinking, cigarette smoking, sex, clinical stage, and age) and subjective symptoms were used to subgroup patients and analyze survival differences. Next, the patients were divided into two groups: a symptomatic group and an asymptomatic group. In the symptomatic group, differences in the incidence of subjective symptoms according to tumor size, tumor location, macroscopic tumor type, and clinical stage were examined. Finally, subjective symptoms were divided into swallowing-related symptoms and other symptoms, and their prognosis was compared. RESULTS: Multivariate Cox regression analysis identified sex [hazard ratio (HR) 1.778; 95% CI 1.004-3.149; p = 0.049], TNM classification (HR 6.591; 95% CI 3.438-12.63; p < 0.001), and subjective symptoms (HR 1.986; 95% CI 1.037-3.803; p = 0.0386) as independent risk factors for overall survival. In the symptomatic group, the mean time from symptom onset to diagnosis was 2.4 ± 4.3 months. The incidence of subjective symptoms differed by clinical stage, and the prognosis of patients with swallowing-related symptoms was significantly worse than that of patients with other symptoms. CONCLUSION: The results of this study suggest that screening by upper gastrointestinal endoscopy, independent of subjective symptoms (especially swallowing-related symptoms), may play an important role in the early detection and improvement of prognosis of ESCC, although further validation in a large prospective study is needed.

BACKGROUND AND AIM: The majority of patients with eosinophilic esophagitis (EoE) are likely to have observable features under narrow-band imaging, namely beige mucosa. However, the histological features and clinical implications of beige mucosa have not been investigated. The aim of this study was to determine whether beige mucosa could serve as an endoscopic marker for predicting active inflammatory sites of EoE. METHODS: We retrospectively analyzed both the narrow-band images and biopsied specimens of 77 esophageal lesions from 35 consecutive patients with EoE. We divided these specimens into two groups: target biopsied specimens from beige mucosa (beige group) and specimens biopsied from non-beige mucosa (non-beige group). The number of eosinophils per high-powered field, thickness of the superficial differentiated cell layer, and depth of the hemoglobin component from the surface layer were compared between the two groups. RESULTS: Forty-four out of the 45 specimens were diagnosed as histological active lesions in the beige group. The sensitivity, specificity, and overall accuracy of beige mucosa in predicting EoE activity were 97.8%, 96.9%, and 97.8%, respectively. Compared with the non-beige group, specimens in the beige group had a significantly thinner superficial differentiated cell layer. CONCLUSIONS: Beige mucosa is associated with thinning of the normal superficial differentiated cell layer, and these histological changes in the active inflammatory sites of EoE could be recognized endoscopically as color differences. Beige mucosa may serve as an endoscopic indicator for predicting the histological activity of EoE.

BACKGROUND: Similar trends in the prevalence of gastroesophageal reflux disease (GERD), obesity, and Helicobacter pylori infection have been observed in Asian and Western countries despite their time differences. However, it is unclear whether the prevalence of gastroesophageal junction adenocarcinomas in Asian countries is increasing. In this review, we discuss the epidemiological trends of gastroesophageal junction adenocarcinoma in Asian countries. SUMMARY: The prevalence of GERD is increasing in Asian countries, but most cases are considered mild. Obesity is a serious problem worldwide, but it is considered less serious in Asia than in Western countries. In Asian countries where gastric cancer is common, both cardiac and noncardiac cancers are associated with high rates of H. pylori infection, which is considered a carcinogenic risk factor for both sites of cancer. The widespread use of H. pylori eradication therapy for chronic gastritis in several Asian countries has not directly led to an increased prevalence of esophageal adenocarcinoma. One of the originating sites of junctional adenocarcinoma in most Asian countries is Barrett's esophagus, with short-segment Barrett's esophagus having much lower carcinogenicity than long-segment Barrett's esophagus. Key Messages: Considering the future trends of several risk factors for gastroesophageal junction adenocarcinoma in Asian countries, it is likely that the incidence of gastroesophageal junction adenocarcinoma will gradually increase, but not at a rate that exceeds that of squamous cell carcinoma, as in Western countries.

BACKGROUND: The incidence of eosinophilic esophagitis (EoE), a Th2-type allergic disease of the esophagus, has increased with the higher prevalence of gastroesophageal reflux disease (GERD). Both conditions are chronic inflammatory diseases with similar clinical presentations, yet their pathogenesis is thought to differ. Recent evidence indicates that forkhead box P3 (FOXP3)-positive regulatory T cells (Tregs) play a critical role in immune tolerance and control of Th2-biased responses in various allergic diseases. AIMS: This study aimed to investigate differences in Treg induction between EoE and GERD and clarify whether this difference was related to the clinicopathological findings of patients with EoE. METHODS: Thirty patients (15 men, 15 women) with EoE and 30 patients (15 men, 15 women) with GERD were included. Patient characteristics, including endoscopic and pathological findings, were compared between the two groups. Immunohistochemistry staining was used to identify T lymphocytes and Tregs. Tregs were identified by CD3 + FOXP3 + staining, and T cells were defined as CD3 + cells. The number of T cells and Tregs in the epithelium was counted, and the average of Tregs/T cells was calculated. RESULTS: The ratio of Tregs/CD3 + T cells in the esophageal epithelium was significantly lower in the EoE group than in the GERD group (9.9% vs. 23.6%, P = 0.0000012). Comparison of the ratio of Tregs/CD3 + T cells by age, gender, endoscopic findings, and histological findings in patients with EoE revealed a significant difference in gender. CONCLUSIONS: Treg induction was impaired, and this effect was more pronounced in male adult patients with EoE than those with GERD.
