RESUMO
BACKGROUND AND AIMS: The endoscopic reference score using white-light imaging (WLI) is utilized for objectively evaluating the severity of findings in patients with eosinophilic esophagitis. A novel image-enhanced endoscopy technique, red dichromatic imaging (RDI), can visualize deeper vessels in the GI tract, which may assess edema more precisely than WLI. METHODS: A total of 21 consecutive patients with eosinophilic esophagitis were prospectively evaluated. Patients were categorized according to 3 grades based on the visibility of vessels with RDI. Clinical features, such as peak eosinophil counts and presence of symptoms, were reviewed. RESULTS: There were 10 patients with RDI Grade 0/1 and 11 patients with RDI Grade 2. Peak eosinophil counts and the prevalence of heartburn were significantly higher in patients with RDI Grade 2 than in patients with RDI Grade 0/1. CONCLUSIONS: The severity of eosinophilic infiltration could be predicted more precisely using RDI than by evaluations with WLI.

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
INTRODUCTION: We investigated the factors associated with synchronous multiple early gastric cancers and determined their localization. METHODS: We analyzed 8,191 patients who underwent endoscopic submucosal dissection for early gastric cancers at 33 hospitals in Japan from November 2013 to October 2016. Background factors were compared between single-lesion (n = 7,221) and synchronous multi-lesion cases (n = 970) using univariate and multivariate analyses. We extracted cases with two synchronous lesions (n = 832) and evaluated their localization. RESULTS: Significant independent risk factors for synchronous multiple early gastric cancer were older age (≥75 years old) (odds ratio [OR] = 1.257), male sex (OR = 1.385), severe mucosal atrophy (OR = 1.400), tumor localization in the middle (OR = 1.362) or lower region (OR = 1.404), and submucosal invasion (OR = 1.528 [SM1], 1.488 [SM2]). Depressed macroscopic type (OR = 0.679) and pure undifferentiated histology OR = 0.334) were more common in single early gastric cancers. When one lesion was in the upper region, the other was more frequently located in the lesser curvature of the middle region. When one lesion was in the middle region, the other was more frequently located in the middle region or the lesser curvature of the lower region. When one lesion was in the lower region, the other was more frequently located in the lesser curvature of the middle region or the lower region. CONCLUSION: Factors associated with synchronous multiple early gastric cancer included older age, male sex, severe mucosal atrophy, tumor localization in the middle or lower region, and tumor submucosal invasion. Our findings provide useful information regarding specific areas that should be examined carefully when one lesion is detected.

BACKGROUND AND AIMS: Data are lacking regarding post-endoscopic submucosal dissection (ESD) bleeding in patients with early gastric cancer (EGC) who take antiplatelet agents (APAs), particularly in those taking thienopyridine and cilostazol. We aimed to clarify the association between the status of APA medication and post-ESD bleeding risk. METHODS: This study is a secondary analysis using data from a recently conducted nationwide multicenter study in Japan. We retrospectively reviewed patients treated with APAs or on no antithrombotic therapy recruited from 33 institutions who underwent ESD for EGC between November 2013 and October 2016. The primary outcome of this study was the relationship between the rate of post-ESD bleeding and the status of each APA medication. RESULTS: A total of 9736 patients were included in the analysis. Among 665 aspirin users, the continuation group was significantly associated with post-ESD bleeding (odds ratio [OR], 2.79; 95% confidence interval [CI], 1.77-4.37). Among 227 thienopyridine users, the aspirin or cilostazol replacement group was not significantly associated with post-ESD bleeding (OR, 1.85; 95% CI, .72-4.78). Among 158 cilostazol users, there was no significant association with post-ESD bleeding, irrespective of medication status. The rate of post-ESD bleeding was approximately 10% to 20% irrespective of the status of APA administration among dual-antiplatelet therapy users. No patients experienced thromboembolic events in this study. CONCLUSIONS: Replacement of thienopyridine with aspirin or cilostazol may be acceptable for minimizing both the risk of post-ESD bleeding and thromboembolism in patients with EGC. In patients on cilostazol monotherapy undergoing ESD, continuation of therapy may be acceptable.

INTRODUCTION: Non-esophageal eosinophilic gastrointestinal disorders (non-EoE EGIDs) are rare, but their prevalence has recently increased. Although it has been reported that one-half of patients with non-EoE EGIDs have intractable clinical courses, their clinical features are not fully understood. METHODS: This is a multicenter retrospective study in which 10 institutions in Japan participated. Clinical databases from January 1998 to December 2020 were reviewed to identify patients with non-EoE EGIDs. A total of 44 patients were identified; they were divided into two groups based on their clinical course: an intractable group and a non-intractable group. The clinical features were compared between the two groups by a logistic regression analysis. Remarkable eosinophilic infiltration (REI) was defined histologically when the maximal counts of mucosal eosinophils reached a threshold level in the respective area of biopsy. RESULTS: Prevalence of drug allergy and eosinophil counts more than 500/µL (EOS), vomiting symptoms, abnormalities of the stomach, duodenum, and jejunum on computed tomography (upper gastrointestinal abnormality on computed tomography [UACT]), and REI were significantly different between the two groups. Among the factors that were potentially associated with an intractable clinical course, logistic regression revealed that REI, EOS, and UACT were significant factors. Based on an analysis of the area under the receiver operator characteristic curve, a combination of REI and EOS had the lowest Akaike's information criterion, indicating the best model to predict an intractable clinical course. CONCLUSIONS: REI may predict an intractable course in patients with non-EoE EGIDs. In addition, the combination of REI and EOS was a better predictor than REI alone.

BACKGROUND: Red dichromatic imaging (RDI) is a new imaging technology that has been closely correlated with the activity index of ulcerative colitis (UC). Although the RDI score has been developed no study has validated a correlation between the RDI score and the activity index of UC. Therefore, this study aims to validate the RDI score prospectively. METHODS: A total of 34 patients with UC in whom colonoscopy was scheduled between May 2019 and October 2021 at our hospital were enrolled prospectively. MES, UCEIS, RDI scores, and Nancy index were evaluated in a blinded fashion. We evaluated the correlation between RDI and WLI scores using still images with histology. RESULTS: We analyzed 191 sites of colorectum. RDI score showed the positive correlation with UCEIS (r = 0.74 P < 0.0001) and MES (r = 0.78 P < 0.0001). RDI score also showed the positive correlation with Nancy index (r = 0.63 P < 0.0001). RDI score was more strongly correlated with Nancy index than UCEIS (r = 0.51) and MES (r = 0.48). CONCLUSIONS: When comparing still images of RDI and WLI scores, we showed RDI had a higher correlation to histology than WLI.

BACKGROUND: Management of bleeding during endoscopic submucosal dissection (ESD) is critical. Red Dichromatic Imaging (RDI), a novel image-enhanced endoscopy technology, has been reported to improve the visibility of deep vessels and bleeding source compared to white light imaging (WLI). We hypothesized that using RDI during the entire cutting process (full time RDI ESD: FTR-ESD), higher R0 resection rate, shorter procedure time and fewer complications could be achieved. Therefore, the aims of the present study were to investigate the efficacy and safety of FTR-ESD. METHODS: This retrospective observational study included a total of 82 consecutive patients who underwent ESD by a single expert endoscopist for 40 esophageal, 17 gastric and 25 colorectal cancers at our institution from January 2018 to March 2021. The clinicopathological data were collected from patients' medical records and the treatment outcomes were analyzed according to the treatment phase (early; 57 WLI-ESD and late; 25 FTR-ESD). RESULTS: The median of the greatest diameter of resected specimen was 40.0 mm. The median procedure time was relatively shorter in the FTR-ESD group (35 min) than in the WLI-ESD group (40 min), but the difference was not statistically significant (p = 0.34). The median dissection speed in the FTR-ESD group (27.23 mm2/min) was significantly faster than that in the WLI-ESD group (20.94 mm2/min) (p = 0.025). The dissection speed was not different among different organs. A multivariate analysis revealed that tumor size (more than 30 mm) and FTR-ESD were significant independent factors contributing to faster dissection speed (p < 0.05). There were no significant differences in the rates of en bloc resection, HM0, VM0 or occurrence of adverse events between WLI-ESD and FTR-ESD. CONCLUSIONS: FTR-ESD significantly increases the dissection speed compared to WLI-ESD. FTR-ESD can be performed safely and therapeutic outcomes in FTR-ESD are comparable with WLI-ESD. A further multicenter prospective study is warranted to confirm our results.

BACKGROUND: Chicago classification version 4.0 suggests additional maneuvers, such as upright testing, multiple rapid swallows (MRS), and the rapid drink challenge (RDC), for high-resolution manometry (HRM) to minimize ambiguity in the diagnosis of esophageal motility disorders. The present study investigated normative thresholds for these new metrics using the Starlet system as well as their diagnostic yields for relevant esophagogastric outflow disorders (EGJOD). METHODS: In study 1, 30 asymptomatic volunteers prospectively performed HRM including MRS and RDC in the supine/upright positions. We calculated normative thresholds for the new metrics, such as upright integrated relaxation pressure (IRP), upright intrabolus pressure (IBP), and IRP during RDC (RDC-IRP). In study 2, we retrospectively analyzed the HRM tracings of 82 patients who underwent HRM in both positions at our hospital to assess the diagnostic yields of HRM metrics. RESULTS: Based on the results of study 1, we adopted the following normative thresholds: upright IRP < 20 mmHg, upright IBP < 21 mmHg, and RDC-IRP < 16 mmHg. In study 2, 45 patients with dysphagia or chest pain were included in the analysis to identify predictive factors for clinically relevant esophagogastric outflow disorders (true EGJOD). Supine/upright IRP, RDC-IRP, and pan-esophageal pressurization > 20 mmHg during RDC (RDC-PEP) predicted true EGJOD with RDC-PEP with the highest sensitivity of 91.7%. CONCLUSIONS: HRM with additional maneuvers may facilitate the diagnosis of clinically relevant EGJOD.

BACKGROUND: Although dysphagia and chest pain are the two most common symptoms in patients with achalasia, the mechanism of evoking symptoms is still unknown. The aim of this study was to reveal the relationship between symptoms and the subtypes of achalasia defined by the Chicago classification. METHODS: A total of 71consecutive patients with newly diagnosed achalasia were enrolled between March 2009 and December 2017. Esophageal motility was assessed by high-resolution manometry (HRM) with the Chicago classification v 3.0. and esophagograms. Their symptoms were evaluated with structured self-reported questionnaires focused on dysphagia and chest pain. Symptom profiles and radiographic findings according to the manometric subtypes were investigated. RESULTS: Among the total 71 patients, 69 patients (97%) had dysphagia and 39 patients (54%) had chest pain. Regarding dysphagia, type II patients reported dysphagia in the throat the most, while types I and III patients mostly felt it in the epigastrium. Type II patients often felt dysphagia at the time of swallowing (41%), but this was reported in only 8.7% of Type I and 33% of Type III patients (p = 0.02). Concerning chest pain, Type I patients rarely had pain during meals (14%), but more often while sleeping (43%) and in early morning (43%), while type III patients often had pain during meals (67%). Type III patients reported that solid food caused pain more often than other types (I/II/III 0/10/33%, p = 0.09). CONCLUSIONS: Detailed symptoms of achalasia, such as its site and timing, varied by subtypes. The status of the esophageal body might induce those differences in symptoms.

This systematic review was performed to investigate the superiority of proton beam therapy (PBT) to photon-based radiotherapy (RT) in treating esophageal cancer patients, especially those with poor cardiopulmonary function. The MEDLINE (PubMed) and ICHUSHI (Japana Centra Revuo Medicina) databases were searched from January 2000 to August 2020 for studies evaluating one end point at least as follows; overall survival, progression-free survival, grade ≥ 3 cardiopulmonary toxicities, dose-volume histograms, or lymphopenia or absolute lymphocyte counts (ALCs) in esophageal cancer patients treated with PBT or photon-based RT. Of 286 selected studies, 23 including 1 randomized control study, 2 propensity matched analyses, and 20 cohort studies were eligible for qualitative review. Overall survival and progression-free survival were better after PBT than after photon-based RT, but the difference was significant in only one of seven studies. The rate of grade 3 cardiopulmonary toxicities was lower after PBT (0-13%) than after photon-based RT (7.1-30.3%). Dose-volume histograms revealed better results for PBT than photon-based RT. Three of four reports evaluating the ALC demonstrated a significantly higher ALC after PBT than after photon-based RT. Our review found that PBT resulted in a favorable trend in the survival rate and had an excellent dose distribution, contributing to reduced cardiopulmonary toxicities and a maintained number of lymphocytes. These results warrant novel prospective trials to validate the clinical evidence.

BACKGROUND AND AIM: Despite the widespread use of endoscopic submucosal dissection (ESD) for early gastric cancer, post-ESD bleeding remains a significant problem. Intragastric pH plays an important role in intragastric bleeding. Because gastric acid secretion contributes to intragastric pH, both the presence or absence of Helicobacter pylori infection and the degree of gastric mucosal atrophy may affect bleeding. The present study aimed to clarify the relationship between post-ESD bleeding and the degree of gastric mucosal atrophy based on H. pylori infection status. METHODS: We included 8170 patients who underwent ESD for early gastric cancer at 33 hospitals in Japan from November 2013 to October 2016. We analyzed the risk factors contributing to post-ESD bleeding. RESULTS: There were 3935 H. pylori-positive patients and 4235 H. pylori-negative patients. A nonsevere degree of gastric mucosal atrophy was an independent risk factor for post-ESD bleeding in H. pylori-negative patients (odds ratio: 1.51, P = 0.007), but not in H. pylori-positive patients (odds ratio: 0.91, P = 0.600). Further, in H. pylori-negative, but not H. pylori-positive, patients, the rate of post-ESD bleeding increased in a stepwise manner for patients continuing antithrombotic drug use, patients who withdrew antithrombotic drug use, and antithrombotic drug nonusers. CONCLUSIONS: Nonsevere gastric mucosal atrophy was a risk factor for post-ESD bleeding in early gastric cancer in H. pylori-negative patients but not in H. pylori-positive patients.

INTRODUCTION: Few studies have focused on bleeding following endoscopic submucosal dissection (ESD) in surgically altered stomach. We aimed to reveal the bleeding risk in surgically altered stomach following ESD for early gastric cancer (EGC). METHODS: We enrolled patients with ESD for EGC at 33 institutions between 2013 and 2016. In study 1, we evaluated bleeding risk following ESD in surgically altered stomach, compared with whole stomach. In study 2, we evaluated factors associated with bleeding following ESD in patients with surgically altered stomach. RESULTS: Of 11,452 patients, 445 patients had surgically altered stomach with the bleeding rate following ESD of 4.9%. In study 1, the bleeding risk in surgically altered stomach was not significant (odds ratio [OR], 1.37; 95% confidence interval [CI], 0.87-2.17) in the multivariate logistic regression analysis. No significant results were obtained when the surgically altered stomach was subdivided into various types. In study 2, the multivariate logistic regression analysis revealed that independent risk factors for bleeding following ESD were ischemic heart disease (OR, 7.52; 95% CI, 2.00-28.25) and P2Y12 receptor antagonist (OR, 4.81; 95% CI, 1.21-19.14). DISCUSSION/CONCLUSION: In this nationwide study, we found that the bleeding risk of surgically altered stomach following ESD for EGC did not significantly differ from that of whole stomach. The risk factors for ESD in patients with surgically altered stomach were ischemic heart disease and P2Y12 receptor antagonist.

BACKGROUND: Information on whether there is a relationship between hospital volume and bleeding after endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) is limited. This study aimed to compare the bleeding rates after ESD for EGC according to the hospital volume. METHODS: Patients who underwent ESD for EGC at 33 institutions in Japan between November 2013 and October 2016 were included in this multicenter retrospective study. Hospital volume was categorized into three groups, based on the average annual number of ESD procedures: low- and medium-volume group (LMVG), high-volume group (HVG), and very high-volume group (VHVG). The bleeding rate after ESD for EGC was compared between the three hospital volume groups after propensity score matching. RESULTS: A total of 10,320 patients, including 2797 patients in the LMVG, 4646 patients in the HVG, and 2877 patients in the VHVG, were identified. Propensity score matching yielded 2002 patients in each hospital volume group, with an improved balance of confounding variables between the three groups. The bleeding rates in the LMVG, HVG, and VHVG were 4.3%, 3.7%, and 4.9%, respectively, and no significant difference was noted between the three groups. CONCLUSIONS: The bleeding rate after ESD for EGC did not differ between hospitals in Japan. The finding indicated that ESD for EGC is equally feasible across Japanese hospitals of different volumes regarding bleeding after ESD.

OBJECTIVES: To verify the efficacy and safety of red dichromatic imaging (RDI) in hemostatic procedures during endoscopic submucosal dissection (ESD). METHODS: This is a multicenter randomized controlled trial of 404 patients who underwent ESD of the esophagus, stomach, colorectum. Patients who received hemostatic treatments by RDI during ESD were defined as the RDI group (n = 204), and those who received hemostatic treatments by white light imaging (WLI) were defined as the WLI group (n = 200). The primary endpoint was a shortening of the hemostasis time. The secondary endpoints were a reduction of the psychological stress experienced by the endoscopist during the hemostatic treatment, a shortened treatment time, and a non-inferior perforation rate, in RDI versus WLI. RESULTS: The mean hemostasis time in RDI (n = 860) was not significantly shorter than that in WLI (n = 1049) (62.3 ± 108.1 vs. 56.2 ± 74.6 s; P = 0.921). The median hemostasis time was significantly longer in RDI than in WLI (36.0 [18.0-71.0] vs. 28.0 [14.0-66.0] s; P = 0.001) in a sensitivity analysis. The psychological stress was significantly lower in RDI than in WLI (1.71 ± 0.935 vs. 2.03 ± 1.038; P < 0.001). There was no significant difference in the ESD treatment time between RDI (n = 161) and WLI (n = 168) (58.0 [35.0-86.0] vs. 60.0 [38.0-88.5] min; P = 0.855). Four perforations were observed, but none of them took place during the hemostatic treatment. CONCLUSIONS: Hemostatic treatment using RDI does not shorten the hemostasis time. RDI, however, is safe to use for hemostatic procedures and reduces the psychological stress experienced by endoscopists when they perform hemostatic treatment during ESD. UMIN000025134.

We examined 171 patients with novel coronavirus disease 2019 (COVID-19) with liver injury in the respiratory failure groups and the nonrespiratory failure groups and investigated 41 patients with moderate II COVID-19 with respiratory failure who received dexamethasone (Dex) monotherapy in the liver injury group and the nonliver injury group at the time before treatment. The respiratory failure group had 64% more liver damage than the nonrespiratory failure group, was older, had more men, and had significantly more complications from lifestyle-related diseases such as hypertension and diabetes. Obesity was more common in the liver injury group prior to Dex monotherapy, and the liver CT value was significantly lower than in the nonliver injury group. Liver injury worsened in 41% of patients after Dex monotherapy, but there was no significant difference in the frequency before Dex monotherapy between the liver injury group and the nonliver injury group, and the degree of liver injury was mild in all cases, improving in 38% of the liver injury group. Dex monotherapy was a safe treatment for moderate II COVID-19, which frequently resulted in liver injury.

A woman in her 30s was diagnosed with ulcerative colitis (UC) 4 years ago and treated with tacrolimus, azathioprine, and prednisolone 5mg (PSL). Skin ulcers appeared on the right lower leg during the course of treatment, diagnosed as pyoderma gangrenosum (PG). The patient initially improved with an increased PSL and infliximab dose, but then developed multiple skin ulcers and folliculitis throughout her body. She was transferred to our hospital for PG exacerbation treatment. She developed fever after transfer and contrast-enhanced computed tomography showed multiple abscesses in the lungs and kidneys. PSL was decreased and infliximab was discontinued. Antibiotic therapy and granulocyte/monocyte apheresis (GMA) were started. Fever persisted even after antibiotic treatment, and her general condition did not improve. A right renal abscess puncture was performed. Pus was sterile. A sterile abscess associated with PG was suspected. The PSL dose was increased to 1mg/kg and infliximab restarted. Thereafter, the patient's general condition improved, and both lung and renal abscesses contracted. Skin ulcer epithelialization was also observed. Abdominal symptoms were mild during the course of the disease, and colonoscopy showed only a localized ulcerative lesion in the rectum. The patient was later transferred to the department of dermatology at our hospital for PG treatment. Aseptic abscesses are caused by neutrophil infiltration without infection and have been reported to be associated with neutrophilic dermatosis and inflammatory bowel disease. UC-associated aseptic abscess is rare. This is only the sixth case in Japan. Aseptic abscesses can occur in various sites, including subcutaneous and deep organs, but this is the first kidney abscess case. In previous reports, PSL, infliximab, colchicine, and infliximab+GMA were used for aseptic abscesses associated with UC. They all showed abscess reduction. Aseptic abscesses associated with PG should be considered if abscess lesions occur during the course of UC, and a treatment strategy including enhanced immunosuppression should be considered.

BACKGROUND: Jackhammer esophagus (JE) is a hypercontractile esophageal motility disorder diagnosed using high-resolution manometry (HRM). We sought to determine the clinical presentation and therapeutic data of patients with JE in Japan. METHODS: The study included patients with JE, diagnosed through HRM performed for suspicious esophageal motility disorders. Demographics, esophagogastroduodenoscopy, radiology, and therapy data were collected from patient charts. RESULTS: Among the 4,412 HRM tests performed, 89 patients (61.6 ± 13.4 years; 64 males, 25 females) were diagnosed with JE (2.0%). Dysphagia was the most frequent symptom (80%), followed by chest pain (40%) and heartburn (25%). Esophagogastroduodenoscopy showed abnormal findings in 32% of patients: corkscrew/rosary beads appearance in 26%, narrowing in 11%. Eosinophilic infiltration (> 15 eosinophils/high power field) was diagnosed in 21%. Esophagography showed abnormal findings in 9% of the patients. For the initial therapy, 47 patients received medical treatment followed by peroral endoscopic myotomy (21 patients) and laparoscopic myotomy (two patients). Thirteen patients did not receive any treatment and 10 of those (77%) reported spontaneous resolution of symptoms. Patients who required invasive treatment experienced severe disability in their quality of life and greater maximal distal contractile integral than those who did not. CONCLUSIONS: HRM showed that the prevalence of JE was very low (2%). Esophagogastroduodenoscopy revealed some characteristic features of JE in patients. Some patients showed improvement of symptoms without invasive treatments. Follow-up with/without medical treatment should be considered before performing invasive treatment in patients whose distal contractile integral is relatively low and the quality of life is not impaired.

The consumption of fruit and vegetables was reported to be associated with a reduced risk of esophageal cancer (EC) in many studies of esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC) from different regions worldwide. Therefore, to provide precise information to reduce the risk of EC in Asia, we performed a systematic review and meta-analysis of studies conducted in the Asian region about fruit and vegetable consumption and the risk of EC. We searched the MEDLINE (PubMed) and ICHUSHI (Japana Centra Revuo Medicina) databases from January 2010 to December 2020. The summary relative risk (SRR) and 95% CI were calculated using a random-effects model. In addition, I2 statistics were used to detect heterogeneity. Twenty-two studies were eligible for meta-analysis (16 case-control studies and 6 cohort studies). The SRR for the lowest versus highest fruit consumption was 0.64 (95% CI 0.53-0.77, I2 = 82%). That for the lowest versus highest vegetable consumption was 0.61 (95% CI 0.50-0.74, I2 = 81%). Based on subgroup analysis, a validated Food Frequency Questionnaire (FFQ) was significantly associated (SRR for fruit: 0.54; 95% CI 0.40-0.74, SRR for vegetable: 0.60; 95% CI 0.48-0.76) with low heterogeneity (I2 = 48% for fruit, I2 = 0% for vegetables). Egger's funnel plot asymmetry test demonstrated publication bias (P < 0.001 for fruit, P = 0.009 for vegetables). Fruit and vegetable consumption might be associated with a lower risk of EC in the Asian region. However, further substantial prospective studies with a validated FFQ and well-controlled important confounding factors are required to confirm the association.

Alcohol consumption is a major risk factor for esophageal cancer. In Asia, heavy drinkers are considered to have a higher risk of esophageal cancer than nondrinkers and light drinkers. However, no study has shown an association between alcohol reduction and the morbidity of esophageal cancer in Asian heavy drinkers. Therefore, this study investigated the significance of reducing alcohol consumption to prevent esophageal cancer in Asian heavy drinkers by conducting a systematic review and meta-analysis. The MEDLINE (PubMed) and ICHUSHI (Japana Centra Revuo Medicina) databases were searched from January 1995 to December 2020. The hazard ratio (HR) and 95% confidence interval (CI) were calculated using a random-effects model. I2 statistics were used to detect heterogeneity. This study included 21 articles in the qualitative synthesis. Light drinkers and heavy drinkers were categorized based on alcohol consumption amount as ≤ 25 ethanol g/day and ≥ 66 ethanol g/day, respectively, as described in many previous studies, and five cohort studies were eligible for this meta-analysis. The HR of esophageal cancer among heavy drinkers versus nondrinkers was 4.18 (95% CI 2.34-7.47, I2 = 74%). On the other hand, the HR of esophageal cancer among light drinkers was 1.82 compared with nondrinkers (95% CI 1.57-2.10, I2 = 0%). Heavy drinkers have a higher esophageal cancer incidence than light drinkers and nondrinker. It is possible that alcohol reduction may decrease the risk of esophageal cancer in Asian heavy drinkers.
