RESUMEN
OBJECTIVE: This study was performed to evaluate whether the use of CAD EYE (Fujifilm, Tokyo, Japan) for colonoscopy improves colonoscopy quality in gastroenterology trainees. METHODS: The patients in this multicenter randomized controlled trial were divided into Group A (observation using CAD EYE) and Group B (standard observation). Six trainees performed colonoscopies using a back-to-back method in pairs with gastroenterology experts. The primary end-point was the trainees' adenoma detection rate (ADR), and the secondary end-points were the trainees' adenoma miss rate (AMR) and Assessment of Competency in Endoscopy (ACE) tool scores. Each trainee's learning curve was evaluated using a cumulative sum (CUSUM) control chart. RESULTS: We analyzed data for 231 patients (Group A, n = 113; Group B, n = 118). The ADR was not significantly different between the two groups. Group A had a significantly lower AMR (25.6% vs. 38.6%, P = 0.033) and number of missed adenomas per patient (0.5 vs. 0.9, P = 0.004) than Group B. Group A also had significantly higher ACE tool scores for pathology identification (2.26 vs. 2.07, P = 0.030) and interpretation and identification of pathology location (2.18 vs. 2.00, P = 0.038). For the CUSUM learning curve, Group A showed a trend toward a lower number of cases of missed multiple adenomas by the six trainees. CONCLUSION: CAD EYE did not improve ADR but decreased the AMR and improved the ability to accurately locate and identify colorectal adenomas. CAD EYE can be assumed to be beneficial for improving colonoscopy quality in gastroenterology trainees. TRIAL REGISTRATION: University Hospital Medical Information Network Clinical Trials Registry (UMIN000044031).

BACKGROUND AND AIMS: Pharmacokinetic parameters, such as drug plasma level at trough, time to maximum plasma concentration (Tmax), and coagulation factor Xa (FXa) activity generally predict factors for the anticoagulant effects of direct oral anticoagulants (DOACs). Although GI bleeding is a major adverse event after endoscopic submucosal dissection (ESD), little is known about the association between post-ESD bleeding in patients taking DOACs and the pharmacologic parameters. This study aimed to evaluate pharmacologic risk factors for post-ESD bleeding in patients taking DOACs. METHODS: We prospectively evaluated the incidence of post-ESD bleeding in patients taking DOACs between April 2018 and May 2022 at 21 Japanese institutions and investigated the association with post-ESD bleeding and pharmacologic factors, including plasma concentration and FXa activity at trough and Tmax. RESULTS: The incidence of post-ESD bleeding was 12.8% (14 of 109; 95% confidence interval [CI], 7.2-20.6). Although plasma DOAC concentration and plasma level/dose ratio at trough and Tmax varied widely among individuals, a significant correlation with plasma concentration and FXa activity was observed (apixaban: correlation coefficient, -0.893; P < .001). On multivariate analysis, risk factors for post-ESD bleeding in patients taking DOACs were higher age (odds ratio [OR], 1.192; 95% CI, 1.020-1.392; P = .027) and high anticoagulant ability analyzed by FXa activity at trough and Tmax (OR, 6.056; 95% CI, 1.094-33.529; P = .039). CONCLUSIONS: The incidence of post-ESD bleeding in patients taking DOACs was high, especially in older patients and with high anticoagulant effects of DOACs. Measurement of pharmacokinetic parameters of DOACs may be useful in identifying patients at higher risk of post-ESD bleeding.
RESUMEN
PURPOSE: Therapeutic efficacy of ustekinumab in the real-world data is limited in patients with refractory Crohn's disease (CD). In addition, factors predictive of better therapeutic efficacy of ustekinumab remains unsolved in CD. We aimed to evaluate therapeutic efficacy of ustekinumab in patients with refractory CD and to identify the factors associated with the efficacy of ustekinumab. METHODS: We retrospectively analyzed the clinical data of 72 patients treated with ustekinumab for refractory CD. Therapeutic efficacy was assessed at weeks 8, 26, 52, and 104 on the basis of dual remission, defined as the combination of Crohn's Disease Activity Index < 150 and CRP < 0.3 mg/dL, and factors predictive of the induction and maintenance of dual remission were investigated. The cumulative continuation rates and safety of ustekinumab were assessed. RESULTS: The dual remission rates at weeks 8, 26, 52, and 104 were 31.9%, 37.9%, 47.5%, and 42.6%, respectively. A short disease duration (≤ 2 years) and higher baseline serum albumin levels (≥ 3.1 g/dL) were positively associated with dual remission at weeks 8 and 52. Meanwhile, higher serum CRP levels (≥ 1.19 mg/dL) were negatively associated with dual remission at week 8. The cumulative ustekinumab continuation rate was favorable, and no severe adverse events were found. CONCLUSION: A short disease duration and higher baseline serum albumin levels might be predictive of favorable therapeutic efficacy of ustekinumab in refractory CD. Induction efficacy appears to be lower in patients with higher serum CRP levels.

BACKGROUND: The STRIDE-II position statement has established endoscopic healing as the long-term target of treatment for inflammatory bowel disease, and ileocolonoscopy is considered the gold standard for assessment of endoscopic healing. However, precise assessment of endoscopic healing cannot be achieved by ileocolonoscopy alone in patients with Crohn's disease (CD). SUMMARY: Approximately 70-80% of patients with CD have small bowel disease, and intestinal complications develop more frequently in the small bowel than in the colorectum. The recent advent of small bowel capsule endoscopy and balloon-assisted enteroscopy has not only clarified the higher incidence of proximal small bowel lesions but has also revealed the presence of such lesions as a possible risk factor for poor disease outcomes. Evidence has shown that the therapeutic efficacy of biologics may differ between the small bowel and the colorectum. In the postoperative setting, it was recently recognized that intestinal lesions other than those at the anastomotic site should be carefully monitored considering the risk of postoperative recurrence. However, there are some obstacles to implementing endoscopic assessment of the entire small bowel and colorectum. Inflammatory biomarkers might play important roles in such scenarios, but the predictive value of biomarkers for small bowel endoscopic healing remains controversial. KEY MESSAGES: Endoscopic assessment of the small bowel is indispensable for improvement of the long-term outcome of CD. The validity of endoscopic healing and transmural healing as long-term targets remains to be fully elucidated.

BACKGROUND AND AIM: This study aimed to compare patients with and without sedation during emergency endoscopy for upper gastrointestinal bleeding (UGIB) and to clarify the safety and efficacy of sedation in emergency endoscopy. METHODS: We retrospectively collected 389 patients who underwent emergency endoscopy for UGIB at Ureshino Medical Center from 2016 to 2021. Patients were divided into two groups: sedation group during emergency endoscopy and nonsedation group. Clinical characteristics, patient status on admission, and UGIB etiology were evaluated. Treatment outcomes and adverse events were evaluated using propensity score matching (PSM), and risk factors for mortality from UGIB were investigated using Cox multivariate analysis. RESULTS: The sedation group was significantly younger, composed of a higher proportion of males, and had chronic liver disease. Blood pressure and hemoglobin level on admission were significantly higher in the sedation group. The main cause of bleeding was peptic ulcer, which was significantly higher in the nonsedation group. PSM created 133 matched pairs. The success rate of endoscopic hemostasis was similar in both groups, and procedure time was significantly shorter in the sedation group than in the nonsedation group (17.6 ± 10.0 versus 20.2 ± 10.2 min, P = 0.04). There were no significant differences in adverse events between groups. Cox multivariate analyses revealed that red blood cell transfusion [hazard ratio (HR) 4.45, P < 0.02] and rebleeding (HR 3.30, P = 0.03) were associated with increased risk of 30-day mortality from UGIB. CONCLUSIONS: Sedation reduced the procedure time during emergency endoscopy for UGIB. Sedation during emergency endoscopy for UGIB is acceptable for safe endoscopic procedures.

We held four upper gastrointestinal tract advanced diagnostic endoscopy sessions from the 89th to the 92nd Congress of the Japan Gastroenterological Endoscopy Society. The most common region addressed was the stomach in 25 presentations, followed by the esophagus in 23, duodenum in five, and other in one. Looking at techniques discussed, the most common image enhancement method discussed was narrowband imaging in 29 presentations, blue laser imaging, and linked color imaging (LCI) in 10 each, dual red imaging in three, and autofluorescence imaging in one. Furthermore, there were presentations of new techniques such as M-Chromo-LCI and acetic acid-indigo carmine mixture LCI. There were also six presentations regarding probe-based confocal laser endomicroscopy, and one of endocytoscopy techniques. We also saw presentations of images of gastric subepithelial tumors within the submucosa, 3D endoscopy, the development of computer-aided detection systems for early cancers, and fluorescent imaging.

A 59-year-old female patient underwent surgery for invasive lobular carcinoma of the right breast 12 years ago. The final diagnosis was invasive lobular carcinoma (T4N1M0 stage IIIB). She underwent chemotherapy, radiotherapy, and hormonal therapy after surgery. She had abdominal bloating and vomiting 12 years after surgery. Contrast-enhanced computed tomography (CECT) and esophagogastroduodenoscopy showed edematous thickening from the stomach to the duodenum and moderate amounts of ascites. Lymph node metastasis was not observed. Biopsy specimens of the stomach revealed signet ring cell carcinoma. Immunochemical studies (ER, GCDFP-15, MUC1, MUC5AC, and MUC6) confirmed gastroduodenal metastasis of invasive lobular carcinoma. Ascites disappeared after she underwent chemotherapy with paclitaxel and bevacizumab; however, wall thickening had spread from the lower esophagus to the stomach, small intestine, colon, and rectum on the CECT. She died 7 months after the diagnosis of gastroduodenal metastasis. Herein, we report a case of invasive lobular carcinoma of the breast with extensive digestive tract metastasis.

BACKGROUND: This study aimed to evaluate the usefulness of discharge standards in outpatients undergoing sedative endoscopy by comparing the modified post-anesthetic discharge scoring system (MPADSS) and the modified Aldrete score. METHODS: We prospectively enrolled 376 outpatients who underwent gastrointestinal endoscopy under midazolam sedation; 181 outpatients were assessed regarding discharge after sedative endoscopy using the MPADSS (group M), and 195 patients were assessed by the modified Aldrete score (group A). The clinical characteristics, types of endoscopy, endoscopic outcomes, and anesthesia outcomes were evaluated between the two groups. We compared discharge score, recovery time, and adverse events using propensity-score matching. RESULTS: Propensity-score matching created 120 matched pairs. The proportion of patients who had a recovery time within 60 min after endoscopy was significantly higher in group A than that in group M (42.5% versus 25.0%, respectively; P < 0.01). The proportion of patients who required > 120 min of recovery time after endoscopy was significantly lower in group A than that in group M (0.0% versus 5.0%, respectively; P = 0.03). However, significantly more patients had drowsiness at discharge in group A compared with group M (19.1% versus 5.0%, respectively; P < 0.01). There was no significant difference in the adverse event rate within 24 h of discharge between the groups. CONCLUSIONS: Patients assessed by the modified Aldrete score were allowed to discharge earlier than those assessed by the MPADSS. However, a patient's level of consciousness should be assessed carefully, especially in patients who visit the hospital alone.

BACKGROUND AND AIM: Elobixibat is a novel ileal bile acid transporter inhibitor. This study aimed to compare the efficacy, tolerability, and safety of the combination of elobixibat and 1 L of polyethylene glycol formulation containing ascorbic acid (PEG-Asc) solution versus the combination of sodium picosulfate and 1-L PEG-Asc solution as bowel preparation for colonoscopy. METHODS: This multi-center, randomized, observer-blinded, non-inferiority study recruited 210 outpatients who were assigned to either the elobixibat plus 1-L PEG-Asc group (group A) or the sodium picosulfate plus 1-L PEG-Asc group (group B). The quality of the bowel cleansing level was assessed by the Boston Bowel Preparation Scale (BBPS) and compared the bowel cleansing level between the groups. Data regarding bowel preparation time, patients' tolerability, and adverse events were also analyzed. RESULTS: Data for 196 patients (99 in group A and 97 in group B) were analyzed finally. BBPS was comparable between group A and B (8.3 ± 0.9 vs. 8.3 ± 0.7; P = 0.88). Consequently, the adequate bowel preparation rate in groups A and B was 95.0% and 99.0%, respectively (-4.0%, 95% CI -9.3 to 1.5). Bowel preparation time in group A was similar to that in group B (348.2 ± 79.8 min vs. 330.8 ± 82.5 min; P = 0.13), whereas, sleep disturbance was significantly less frequent in group A than in group B (10.2% vs. 22.7%; P = 0.02). CONCLUSIONS: The combination of elobixibat and 1-L PEG-Asc can be considered an alternative bowel preparation for colonoscopy considering the equivalent bowel cleansing effect and less frequent sleep disturbance.

BACKGROUND: The screening and treatment of Helicobacter pylori infection for all junior high students in Saga Prefecture, Japan, were started in 2016. The present study aims to evaluate the influence of adverse reactions on the success of the eradication therapy. METHODS: From 2017 to 2019, 25,006 third-grade junior high school students were tested for urinary anti-H. pylori antibodies. Positive cases were confirmed by H. pylori stool antigen tests. Of the 531 students who were found to be H. pylori-positive, 390 (358 in first-line and 32 in second-line therapy) underwent eradication therapy, and 274 (242 in first-line and 32 in second-line) students actually completed a self-reported form to rate stool consistency (based on the Bristol Stool Scale), the maximum number of bowel movements, and abdominal symptoms during the 7 days of treatment. RESULTS: Among the 274 students, the total of primary and secondary eradication success rates was 87% (95% confidential interval: 82.9-90.1) in intention-to-treat analysis. On days 4, 5, and 6, stool consistency was looser in the primary eradication failure group than in the success group (p < .05). Looser stool consistencies were observed in male students with abdominal pain compared to those who did not experience pain (p < .05). Abdominal pain and diarrhea were detected in 28.5% and 42.7% of the subjects, respectively. The overall incidence of other adverse events was low (n = 8/274, 2.9%), and only two students discontinued treatment because of adverse events. CONCLUSIONS: Softening of the stool was related to the eradication failure in the junior high school students, especially in males with abdominal pain. Adverse effects did not induce discontinuation of the eradication treatment.

OBJECTIVE: The aim of this study was to determine the characteristics of patients without Helicobacter pylori infection who were prescribed antacid medications (potassium-competitive acid blockers, proton pump inhibitors, and/or H2 receptor antagonist) and had no upper gastrointestinal lesions detected by endoscopy. METHODS: This cross-sectional study included the patients who underwent upper gastrointestinal endoscopy in our institution between August 2017 and July 2018. They were aged from 55 to 89 years, had no upper gastrointestinal lesions detected by endoscopy, and no H. pylori infection. Exclusion criteria comprised low-dose aspirin and/or nonsteroidal anti-inflammatory drugs. The subjects were allocated to middle-aged (55-69 years) and older age groups (70-89 years). The relationships between antacid medications and patient lifestyle and comorbidities were evaluated by multivariate analyses. RESULTS: Of the 420 patients, 272 were in the middle-aged group and 148 patients in the older age group. Age was found to be a risk factor for antacid medications in both groups (p = 0.002, p = 0.007). No other lifestyle related factors were risk factors. As to comorbidities, hiatal hernia was positively associated with antacid medications in the middle-aged group (p = 0.002). Hypertension and Ca-blockers were positively associated with prescription of antacids in the older age group (p = 0.013); this association was not significant in the middle-aged group. CONCLUSIONS: Three lifestyle-related and/or comorbidity-associated factors known to exacerbate gastroesophageal reflux, namely, age, hiatus hernia, and Ca-blockers, were associated with prescription of antacid medications, even in patients without endoscopic reflux esophagitis.

This study was to examine the recent trends in upper gastrointestinal bleeding in Japan using a large-scale real-world database. The incidence of upper gastrointestinal bleeding was evaluated in the Japan Medical Data Center claims database of 13,019,713 patients aged 20 to 74 years with traceability for 3 months from 2009 to 2014. The incidence was compared with peptic ulcers and gastroesophageal reflux disease. The prescription of medications was also evaluated. The incidence of bleeding was 0.137%, 0.121%, 0.113%, 0.106%, 0.099%, and 0.105% during 2009 to 2014 with a time-dependent decline (p<0.001). Peptic ulcers (>10 times higher than the incidence of bleeding) decreased with time (p<0.001), whereas gastroesophageal reflux disease increased (p = 0.006). Upper gastrointestinal bleeding was higher in male patients and older patients (60-74 years old) (p<0.001 respectively). The prescription rate of antithrombotic medications and proton pump inhibitors increased from 2009 to 2014 (p<0.001 respectively). The incidence of upper gastrointestinal bleeding decreased from 2009 to 2014 in this relatively large-scale real-world database in Japan, concomitant with the decrease in peptic ulcers. The decreased incidence might have been due to changes in the disease structure and therapeutic strategies over time.
RESUMEN
BACKGROUND: In both Western countries and in Japan, the incidence of colonic diverticular bleeding has increased with increased use of antithrombotic and nonsteroidal anti-inflammatory drugs (NSAIDs). Therefore, the Japan Gastroenterological Association issued guidelines for colonic diverticular bleeding and colonic diverticulitis in Japanese in 2017 and in English in 2019. However, the guidelines contain unresolved problems. Herein, we review the recent treatment trends for colonic diverticular bleeding in Japan. SUMMARY: Colonic diverticular bleeding necessitates frequent blood transfusions due to rebleeding, and patients require prolonged hospitalization. Endoscopic treatment plays an important role in treating diverticular bleeding. Currently, endoscopic band ligation (EBL) and endoscopic clipping are used in Japan for diverticular hemorrhage when the source of the hemorrhage is identified. EBL results in significantly lower early (<30 days) and 1-year rebleeding rates and long-term recurrence rates compared with endoscopic clipping. Furthermore, the proportion of patients requiring transcatheter arterial embolization or surgery after EBL is significantly lower than that following endoscopic clipping. Several reports state that EBL is superior to endoscopic clipping; however, EBL has associated complications, and it is necessary to carefully consider the individual patient. Key Messages: EBL is superior to endoscopic clipping regarding short- and long-term rebleeding rates and the rate of transition to surgery and embolization. Methods for preventing diverticular hemorrhage have not been established, but NSAIDs should be discontinued if possible. Prevention strategies for diverticular bleeding need to be evaluated in studies with large sample sizes.

BACKGROUND/AIMS: Proton pump inhibitors (PPIs) are widely used for the management of acid-related diseases. This study aimed to clarify the status of PPI use in hospitalized patients. METHOD: A retrospective observational study was performed. We analyzed PPI prescription data for the past 8 years (2009-2016) using Diagnosis Procedure Combination survey data from approximately 10,000 patients per year at Saga University Hospital. We investigated the trend in the number of hospitalized patients who were prescribed PPI for the past 8 years and the changes in patient characteristics. RESULTS: We identified 11,009 patients using PPIs throughout the study period. PPI prescription proportions significantly increased over the study period. The use of PPIs increased steadily with increasing age. The proportion of PPIs prescribed was 1.3-times higher among men than compared with women. In most clinical departments, the number of patients prescribed PPIs was up to 3 times higher in the second half of the period (2013-2016) compared with the first half of the period (2009-2012). The number of patients taking concomitant PPIs and anticoagulants or dual antithrombotic combination therapy increased. CONCLUSION: PPI use has increased substantially in hospitalized patients. The prevalence of PPI prescription by doctors other than gastroenterologists also increased.

INTRODUCTION/AIMS: Immune checkpoint inhibitors (ICIs) sometimes cause immune-related adverse events (irAEs), of which there is little information in the literatures. The objective of this study was to characterize the clinical features of gastrointestinal irAEs (GI irAEs). MATERIALS AND METHODS: From a total of 250 patients who were administered anti-PD-1 antibodies (nivolumab and pembrolizumab), we retrospectively identified 9 patients with grade 2 or higher GI irAE based on medical records. Patient characteristics, clinical features, imaging and pathological findings, and treatment course were evaluated. RESULTS: Grade 2 or higher GI irAEs were observed in 9 (3.6%) patients. Of the 9 patients who experienced GI irAE, 8 were male, and mean age was 63.2 years. Five patients received nivolumab and 4 received pembrolizumab. The GI irAEs observed were diarrhea in 7 patients and bloody stool in 2 patients. Grade 2 GI irAEs were identified in 3 patients and grade 3 GI irAEs in 6 patients. The average time from ICI administration to the onset of GI irAEs was 22.2 weeks (range 7-56 weeks) for nivolumab and 19.7 weeks (range 11-28 weeks) for pembrolizumab. Endoscopic findings showed ulcerative colitis-like findings in 3 of 7 patients, and pathological examination revealed crypt epithelial cell apoptosis in 6 of 7 patients. Eight of the 9 patients received steroids, and 2 patients received infliximab additionally. All GI irAEs were manageable. CONCLUSIONS: Because of the lack of specific clinical, imaging, and pathological findings, information of ICI use was indispensable for diagnosis. Although GI irAEs are controllable by steroid and infliximab, further studies regarding management strategy will be needed.

BACKGROUND: Endoscopic retrograde pancreatography (ERCP) is sometimes complicated by post-ERCP pancreatitis (PEP), which is a severe adverse effect. OBJECTIVE: The present study was performed to (i) evaluate the risk factors for PEP and (ii) compare the risk of PEP after ERCP performed in the off hours versus regular hours. METHODS: This retrospective study included 374 patients who underwent ERCP from January 2013 to December 2017. Among these patients, 38 (10.2%) developed PEP. The potential risk factors for PEP were evaluated by multivariate regression analysis, and the risk of PEP was compared between ERCP performed during regular hours and off hours. RESULTS: The independent risk factors for PEP were a relatively younger age (<75 years; p = 0.024), female sex (p = 0.002), a history of pancreatitis (p = 0.044), and performance of pancreatography (p = 0.010). Use of a diclofenac suppository and performance of pancreatic stenting were not preventive for PEP after ERCP. The complication rate of PEP did not differ between ERCP performed during the off hours versus regular hours. CONCLUSIONS: A relatively younger age (<75 years), female sex, a history of pancreatitis, and performance of pancreatography were potential risk factors for PEP, whereas the risk of PEP was not different between ERCP performed during the off hours versus regular hours.

BACKGROUND: The term "acute esophageal mucosal lesion (AEML)" includes black esophagitis, and non-black esophagitis characterized by diffuse circumferential erosions without black-appearing mucosa. Black esophagitis is easily diagnosed, whereas non-black esophagitis is often misdiagnosed as severe reflux esophagitis (sRE). The aim of this study was to determine differences in clinical characteristics of patients with AEML and those with sRE. METHODS: Thirty-nine patients with sRE and 32 patients with AEML were diagnosed on the basis of endoscopic findings from 2009 to 2016. Characteristics assessed included age, sex, medication use, coexisting endoscopic finding, comorbidities, laboratory tests results, and chief complaints. RESULTS: In contrast with sRE, male sex, need for emergency endoscopy, presence of duodenal lesions, hypertension, and renal dysfunction were positively associated with AEML. Analysis of associations between laboratory data and AEML showed that high white blood cell count, blood urea nitrogen, and blood glucose were significantly associated with an increase OR for AEML. CONCLUSIONS: We showed that AEML differed from sRE regarding both endoscopic findings and clinicopathological features. AEML has not been widely recognized, but it should be defined as a distinct inflammatory disease of the esophagus consisting of both black and non-black esophagitis.

BACKGROUND/AIMS: Colonic endoscopic mucosal resection (EMR) is safe for patients without antithrombotic therapy; however, EMR is associated with several risks. This study was performed to evaluate the risk of delayed hemorrhage in patients undergoing EMR without antithrombotic therapy. METHODS: In the present retrospective single-center study, 1,792 patients without antithrombotic therapy underwent colonic EMR from March 2012 to December 2016 at the Saga Medical Centre Koseikan. Risk factors were evaluated with respect to patient and lesion characteristics, the endoscopist's experience, and preventive hemoclips. Delayed hemorrhage was defined as bleeding for which emergency endoscopic hemostasis was applied >24 h after EMR. RESULTS: Among the 1,792 patients, 1,660 with 3,844 tumors were evaluated. Delayed hemorrhage occurred in 43 patients (2.6%) and 46 polyps (1.2%). Preventive hemoclips were applied in 996 patients (60.0%). Univariate analysis indicated that delayed hemorrhage occurred more frequently in young patients (3-39 years, p < 0.001, 40-59 years, p = 0.005) compared to > 60 years and in association with large polyps (> 10 mm, p = 0.003), hemoclip (p = 0.019), and pedunculated polyps (p = 0.024). Multivariate analysis indicated that risk factors for hemorrhage were young age (age of 3-39 years p < 0.001, 40-59 years, p = 0.005) and large polyps (> 10 mm, p < 0.001). The risk of delayed hemorrhage was increased by an estimated 8% with a 1-mm increase in polyp size. CONCLUSION: The present study suggests that young age (under 60 years old) and large polyp size are risk factors for causing delayed hemorrhage after colonic EMR in patients without antithrombotic therapy.

AIMS: The influence of lifestyle-related factors, including smoking and drinking, was evaluated for Helicobacter pylori eradication therapy with vonoprazan or proton pump inhibitors (PPIs). METHODS: Between 2012 and 2016, the medical records of 620 patients receiving H. pylori eradication therapy at Saiseikai Karatsu Hospital were evaluated. Patients had received vonoprazan (20 mg) or PPIs with 200 mg clarithromycin and 750 mg amoxicillin twice daily for 7 days. The influence of lifestyle-related factors on eradication failure was determined in the 2 groups. RESULTS: The eradication rates for vonoprazan and lansoprazole, rabeprazole, and esomeprazole were, respectively, 91.0, 73.8, 72.0, and 84.6%. The vonoprazan eradication rate was significantly higher than those for the PPIs (p < 0.01). Habitual smoking and drinking did not increase eradication failure, and smoking and drinking during the eradication period did not reduce the eradication rate. Metabolic syndrome-related factors including obesity, hypertension, and diabetes mellitus had no negative influence on the eradication rate. Eradication with vonoprazan was more effective compared with that achieved through the use of PPIs. CONCLUSION: Lifestyle-related factors including smoking and drinking did not exacerbate the H. pylori eradication failure, and vonoprazan was more effective than the PPIs.

BACKGROUND: Leukocyte removal therapy (LRT) is an effective treatment for active ulcerative colitis (UC). The present study was performed to evaluate the relapse-free period after LRT and identify risk factors for relapse. METHODS: In total, 94 patients who underwent first-time LRT for remission of moderate to severe UC from April 2004 to March 2016 were enrolled in the present study. The patients were randomly assigned to one of 2 treatments: leukocytapheresis (LCAP; n = 43) or granulocyte and monocyte/macrophage adsorptive apheresis (GMA; n = 51). The 5-year cumulative relapse-free rate and risk factors for relapse were evaluated. RESULTS: The therapeutic response rate was 82% for GMA and 70% for LCAP without a statistically significant difference. The 5-year relapse-free rate was 34.7% in the LRT group. The 5-year relapse-free rate in patients aged > 40 years was 49.9%, which was significantly higher than that in patients aged ≤40 years (22.9%, p < 0.01). The relapse-free period was longer in the older than younger patients. CONCLUSIONS: The relapse-free period after LRT was examined in patients with UC, and 34.7% of patients achieved clinical remission within a 5-year period. The risk factor for early relapse after LRT was younger age.
