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.

This study investigated the trends in idiopathic peptic ulcers, examined the characteristics of refractory idiopathic peptic ulcer, and identified the optimal treatment. The characteristics of 309 patients with idiopathic peptic ulcer were examined. We allocated idiopathic peptic ulcers that did not heal after 8 weeks' treatment (6 weeks for duodenal ulcers) to the refractory group and those that healed within this period to the healed group. The typical risk factors for idiopathic peptic ulcer (atherosclerosis-related underlying disease or liver cirrhosis complications) were absent in 46.6% of patients. Absence of gastric mucosal atrophy (refractory group: 51.4%, healed group: 28.4%; pâ =â 0.016), and gastric fundic gland polyps (refractory group: 17.6%, healed group: 5.9%; pâ =â 0.045) were significantly more common in the refractory group compared to the healed group. A history of H. pylori eradication (refractory group: 85.3%, healed group: 66.0%; pâ =â 0.016), previous H. pylori infection (i.e., gastric mucosal atrophy or history of H. pylori eradication) (refractory group: 48.5%, healed group: 80.0%; pâ =â 0.001), and potassium-competitive acid blocker treatment (refractory group: 28.6%, healed group, 64.1%; pâ =â 0.001) were significantly more frequent in the healed group compared to the refractory group. Thus, acid hypersecretion may be a major factor underlying the refractoriness of idiopathic peptic ulcer.
RESUMO
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: 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: 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.

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.

BACKGROUND/AIM: We evaluated the efficacy of vonoprazan (VPZ), a novel potassium-competitive acid blocker, in patients with proton pump inhibitor (PPI)-refractory gastroesophageal reflux disease (GERD), exhibiting continued pathological esophageal acid exposure (EAE). METHODS: Despite ≥8 weeks of appropriate PPI therapy, patients with -persistent reflux symptoms and pathological EAE times (EAETs ≥4%) were invited to switch to VPZ treatment. After an 8-week-course of once-daily VPZ (20 mg), multichannel intraluminal impedance-pH (MII-pH) monitoring was repeated to compare gastric acid exposure times (GAETs), EAETs, and other reflux parameters relative to the baseline values. Before each MII-pH study, reflux symptom severities were scored using the Gastrointestinal Symptom Rating Scale; erosive esophagitis and fasting plasma gastrin levels were also assessed. RESULTS: From among the 124 patients undergoing MII-pH monitoring, 13 patients (median age, 69 years; females, 64%) were monitored at baseline (while on PPI therapy) and after VPZ therapy. The median GAET associated with VPZ treatment (23.8%) was less than that for PPI treatment (41.1%; p = 0.01), including both daytime and nighttime measurements. VPZ therapy resulted in better median EAET values (4.5%) than did PPI therapy (10.6%) during the 24-h monitoring period (p = 0.055). EAE normalization was achieved in 46% of VPZ-treated patients and was associated with complete gastric acid suppression (p = 0.005). After switching to VPZ, reflux symptoms (p < 0.01) and erosive esophagitis (p = 0.01) improved. CONCLUSION: In patients with PPI-refractory GERD, VPZ provides more potent gastric acid suppression, more effective EAE control, enhanced symptom improvement, and better esophagitis healing than PPIs.

We previously reported that cascade stomach was associated with reflux symptoms and esophagitis. Delayed gastric emptying has been believed to initiate transient lower esophageal sphincter relaxation (TLESR). We hypothesized that cascade stomach may be associated with frequent TLESR with delayed gastric emptying. Eleven subjects with cascade stomach and 11 subjects without cascade stomach were enrolled. Postprandial gastroesophageal manometry and gastric emptying using a continuous 13C breath system were measured simultaneously after a liquid test meal. TLESR events were counted in early period (0-60 min), late period (60-120 min), and total monitoring period. Three parameters of gastric emptying were calculated: the half emptying time, lag time, and gastric emptying coefficient. The median frequency of TLESR events in the cascade stomach and non-cascade stomach groups was 6.0 (median), 4.6 (interquartile range) vs 5.0, 3.0 in the early period, 5.0, 3.2 vs 3.0, 1.8 in the late period, and 10.0, 6.2 vs 8.0, 5.0 in the total monitoring period. TLESR events were significantly more frequent in the cascade stomach group during the late and total monitoring periods. In contrast, gastric emptying parameters showed no significant differences between the two groups. We concluded that TLESR events were significantly more frequent in persons with cascade stomach without delayed gastric emptying.
RESUMO
GERD is a condition in which gastroesophageal reflux(GER) causes either esophageal mucosal break, or troublesome symptoms, or both. It is classified into "erosive GERD" with esophageal mucosal break and "non-erosive GERD" with symptoms alone. Since the diag- nosis is based on symptoms, the medical interview is the most important part in clinical situation. In addition to asking typical symptoms of GERD, a careful interview about extrae- sophageal symptoms might be helpful. Self-reported questionnaires are helpful diagnostic tool of GERD. Appropriate medical interview should include the patient's symptoms, the possible risk factor, and their life style.

BACKGROUND: Patients with proton pump inhibitor (PPI)-resistant nonerosive reflux disease (NERD) include subgroups that have markedly different pathophysiology. This study aimed to clarify the pathophysiology of NERD by esophageal manometry with 24-hour esophageal impedance and pH monitoring. METHODS: Eighteen consecutive outpatients referred to our expert center for functional gastrointestinal motility with suspected PPI-resistant NERD were enrolled. Manometry was performed to detect esophageal motility disorders. Subsequently, 24-hour esophageal impedance and pH monitoring was done while patients were on PPI therapy. RESULTS: Manometry revealed 1 case of achalasia, 1 case of nutcracker esophagus and 3 cases of diffuse esophageal spasm. Three patients had ineffective esophageal motility, with impedance and pH monitoring being performed in 2 of them. Esophageal acid exposure (%time pH <4) was normal in both, but the symptom index (SI) was positive for nonacidic reflux in 1 patient. One of the 10 patients with normal esophageal motility had abnormal esophageal acid exposure. The SI was positive for weakly acidic and nonacidic reflux in 3 of the remaining 9 patients with normal esophageal acid exposure. Five of the other 6 patients seemed to have functional heartburn. CONCLUSION: A substantial percentage (28%) of patients with suspected PPI-resistant NERD had primary esophageal motility disorders. Both nonacidic reflux and weakly acidic reflux are important contributors to the symptoms of patients with PPI-resistant NERD. Esophageal manometry is required to exclude motility disorders, while 24-hour esophageal impedance and pH monitoring is invaluable for assessing symptom-reflux associations and the indications for fundoplication in patients with suspected PPI-resistant NERD.

Background: Gastric cancer (GC) epidemiology and outcomes vary by gender. Methods: We reviewed 18,436 GC patients from 2008 to 2018 and looked for gender differences in clinical characteristics and survival. Results: The gender proportion was 71% male and 29% female. Males had a significantly (p < 0.001) higher proportion of differentiated GC (66.3%) and a lower proportion of undifferentiated GC (26.3%). Diagnosis through medical check-ups was more common in males (30.0% vs. 26.4%, p < 0.001). Clinical staging revealed 54.6% of males and 52.9% of females had localized disease without lymph node metastasis (LNM), while distant metastasis occurred in 17.4% of males and 16.9% of females (p < 0.001). Kaplan-Meier survival curves indicated females had a significantly higher overall survival (p = 0.0018). The survival advantage for females was evident in the early stages, with a significant difference in localized disease without LNM (p < 0.001) and localized disease with LNM (p = 0.0026, log-rank test) but not in the advanced stages. Multivariate Cox regression analysis showed a significantly reduced mortality risk in females (p < 0.001). Conclusions: Significant gender differences exist with regard to pathological type, presentation, clinical stage, and overall survival. These findings suggest gender-specific strategies for screening, diagnosis, and treatment.
RESUMO
BACKGROUNDS: Patients with systemic sclerosis (SSc) often have esophageal motility abnormalities and weak esophago-gastric junction (EGJ) barrier function, which causes proton pump inhibitor (PPI)-refractory reflux esophagitis (RE). The aims of this study were to clarify the current management of RE and prevalence and risk factors of medication-refractory RE in patients with SSc in Japan. METHODS: A total of 188 consecutive patients with SSc who underwent both esophageal high-resolution manometry (HRM) and esophagogastroduodenoscopy (EGD) were reviewed. The presence of RE and grades of the gastroesophageal flap valve (GEFV) were assessed. Esophageal motility was assessed retrospectively according to the Chicago classification v3.0. When RE was seen on a standard dose of PPI or any dose of vonoprazan (VPZ), it was defined as medication-refractory RE. RESULTS: Approximately 80% of patients received maintenance therapy with acid secretion inhibitors regardless of esophageal motility abnormalities. Approximately 50% of patients received maintenance therapy with PPI, and approximately 30% of patients received VPZ. Medication-refractory RE was observed in 30 patients (16.0%). In multivariable analyses, the number of EGD and absent contractility were significant risk factors for medication-refractory RE. Furthermore, combined absent contractility and GEFV grade III or IV had higher odds ratios than did absent contractility alone. CONCLUSIONS: Patients with persistent reflux symptoms and those with absent contractility and GEFV grade III or IV should receive maintenance therapy with strong acid inhibition to prevent medication-refractory RE.

Esophagogastroduodenoscopy (EGD) is performed to rule out organic diseases in the diagnosis of esophageal motility disorders (EMDs). Abnormal endoscopic findings can be observed during EGD, which indicate the presence of EMDs. Several endoscopic findings at both the esophagogastric junction and esophageal body that are related to EMDs have been reported. Gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) could be detected during EGD, and these diseases are often associated with abnormal esophageal motility. Image-enhanced endoscopy (IEE) could improve the detection of these diseases during EGD. Although no report has been published previously on the potential usefulness of IEE in the endoscopic diagnosis of EMDs, IEE can be used to detect disorders that can be associated with abnormal esophageal motility.
RESUMO
BACKGROUND AND AIM: The Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG) is the standard questionnaire used in Japan for the diagnosis of gastroesophageal reflux disease (GERD) and assessment of the response to treatment. We modified the FSSG in order to assess dyspepsia symptoms, and evaluated the modified questionnaire. METHODS: We modified the FSSG by adding two questions on interdigestive and postprandial epigastric pain. We then assessed the modified FSSG with 100 new untreated symptomatic patients presenting to hospital and in 200 subjects undergoing health checks. Endoscopic assessment of the esophagogastric junction was performed according to the modified Los Angeles classification with addition of Grade N (normal appearance) and Grade M (minimal change). Endoscopic images were assessed by five experienced endoscopists blinded to the questionnaire results. RESULTS: The 100 new patients included 16 with erosive GERD (>Grade A), 12 with peptic ulcer, and two with gastric cancer. Among the 70 patients with no evidence of organic disease, the modified FSSG diagnosed functional dyspepsia (FD) in 41 and non-erosive gastric disease (NERD) in 29. A significant difference was seen in the dyspepsia score between patients with FD and NERD. Subjects with endoscopic GERD undergoing health checks had significantly higher scores for all symptoms, reflux symptoms, and dyspeptic symptoms on the modified FSSG. CONCLUSION: The modified FSSG can clearly distinguish FD from NERD, and is useful for the assessment of dyspeptic symptoms.
