RESUMEN
OBJECTIVES: With the increasing use of direct oral anticoagulants (DOACs), managing these agents around endoscopic submucosal dissection (ESD) is crucial. However, due to the need for a large number of cases, studies examining the timing of resumption are lacking, resulting in varied recommendations across international guidelines. We aimed to perform a comparative study about the resumption timing of DOACs after colorectal ESD using a nationwide database in Japan. METHODS: We conducted a retrospective cohort study on colorectal ESD using the Diagnosis Procedure Combination database from 2012 to 2023. Patients using anticoagulants other than DOACs were excluded, and only those who resumed DOACs within 3 days were included. From eligible patients, we divided them into early (the day after ESD) and delayed (2 to 3 days after ESD) resumption groups. We used inverse probability of treatment weighting (IPTW) to assess the delayed bleeding and thromboembolic events within 30 days. Delayed bleeding was defined as bleeding requiring endoscopic hemostasis or blood transfusion after ESD. RESULTS: Of 176,139 colorectal ESDs, 3,550 involved DOAC users, with 2,698 (76%) categorized as early resumption and 852 (24%) categorized as delayed resumption groups. After IPTW adjustment, the early resumption group did not significantly increase delayed bleeding compared to the delayed resumption group (OR, 1.05; 95% CI, 0.78-1.42; P = 0.73). However, it significantly reduced the risk of thromboembolic events (OR, 0.45; 95% CI, 0.25-0.82; P < 0.01). CONCLUSIONS: Resuming DOACs the day after colorectal ESD was associated with reduced thromboembolic events without significant increase in risk of delayed bleeding.
RESUMEN
OBJECTIVES: We aimed to develop and validate a simple scoring system to predict in-hospital mortality after endoscopic variceal ligation (EVL) for esophageal variceal bleeding. METHODS: Data from a 13-year study involving 46 Japanese institutions were split into development (initial 7 years) and validation (last 6 years) cohorts. The study subjects were patients hospitalized for esophageal variceal bleeding and treated with EVL. Variable selection was performed using least absolute shrinkage and selection operator regression, targeting in-hospital all-cause mortality as the outcome. We developed the Hospital Outcome Prediction following Endoscopic Variceal Ligation (HOPE-EVL) score from ß coefficients of multivariate logistic regression and assessed its discrimination and calibration. RESULTS: The study included 980 patients: 536 in the development cohort and 444 in the validation cohort. In-hospital mortality was 13.6% and 10.1% for the respective cohorts. The scoring system used five variables: systolic blood pressure (<80 mmHg: 2 points), Glasgow Coma Scale (≤12: 1 point), total bilirubin (≥5 mg/dL: 1 point), creatinine (≥1.5 mg/dL: 1 point), and albumin (<2.8 g/dL: 1 point). The risk groups (low: 0-1, middle: 2-3, high: ≥4) in the validation cohort corresponded to observed and predicted mortality probabilities of 2.0% and 2.5%, 19.0% and 22.9%, and 57.6% and 71.9%, respectively. In this cohort, the HOPE-EVL score demonstrated excellent discrimination ability (area under the curve [AUC] 0.890; 95% confidence interval [CI] 0.850-0.930) compared with the Model for End-stage Liver Disease score (AUC 0.853; 95% CI 0.794-0.912) and the Child-Pugh score (AUC 0.798; 95% CI 0.727-0.869). CONCLUSIONS: The HOPE-EVL score practically and effectively predicts in-hospital mortality. This score could facilitate the appropriate allocation of resources and effective communication with patients and their families.
RESUMEN
Gastrointestinal bleeding (GIB) is a significant public health concern, predominantly associated with high morbidity. However, there have been no reports investigating the trends of GIB in Japan using nationwide data. This study aims to identify current trends and issues in the management of GIB by assessing Japan's national data. We analyzed National Database sampling data from 2012 to 2019, evaluating annual hospitalization rates for major six types of GIB including hemorrhagic gastric ulcers, duodenal ulcers, esophageal variceal bleeding, colonic diverticular bleeding, ischemic colitis, and rectal ulcers. In this study, hospitalization rates per 100,000 indicated a marked decline in hemorrhagic gastric ulcers, approximately two-thirds from 41.5 to 27.9, whereas rates for colonic diverticular bleeding more than doubled, escalating from 15.1 to 34.0. Ischemic colitis rates increased 1.6 times, from 20.8 to 34.9. In 2017, the hospitalization rate per 100,000 for colonic diverticular bleeding and ischemic colitis surpassed those for hemorrhagic gastric ulcers (31.1, 31.3, and 31.0, respectively). No significant changes were observed for duodenal ulcers, esophageal variceal bleeding, or rectal ulcers. The findings of this study underscore a pivotal shift in hospitalization frequencies from upper GIB to lower GIB in 2017, indicating a potential shift in clinical focus and resource allocation.
RESUMEN
OBJECTIVES: Current guidelines recommend colonoscopy within 24 h for acute lower gastrointestinal bleeding; however, the evidence in support for colonic diverticular hemorrhage (CDH) indications remains insufficient. We use a nationwide database to investigate the effectiveness of early colonoscopy for CDH. METHODS: We conducted a retrospective cohort study using the Japanese Diagnosis Procedure Combination inpatient database and identified patients who were admitted for CDH from 2010 to 2017. Patients who underwent colonoscopy on the same day of admission (early group) were compared with those who underwent colonoscopy on the next day of admission (elective group). The primary outcome was in-hospital mortality, and secondary outcomes were length of hospital stay, total hospitalization cost, fasting period, and the prevalence of re-colonoscopy, interventional radiology or abdominal surgery. Propensity score matching was used to adjust for confounders. RESULTS: We identified 74,569 eligible patients. Patients were divided into the early (n = 46,759) and elective (n = 27,810) groups. After propensity score matching, 27,696 pairs were generated. In-hospital mortality did not significantly differ between the two groups (0.49% in the early group vs. 0.41% in the elective group; risk difference 0.08%; 95% confidence interval -0.02 to 0.19; P = 0.14). The early group had a significantly longer length of hospital stay, higher total hospitalization cost, longer fasting period, and higher prevalence of re-colonoscopy and abdominal surgery. CONCLUSIONS: The effectiveness of early colonoscopy conducted on the same day of admission for CDH could not be confirmed. Early colonoscopy may not result in favorable outcomes in CDH patients.

BACKGROUND: Bleeding can be a serious adverse event of endoscopic sphincterotomy (EST). However, the risk of EST bleeding between direct oral anticoagulant (DOAC) users and those who received no antithrombotic agents has not been clarified. This study analyzed the risk factors for bleeding after EST in patients on DOAC and evaluated the Japan Gastroenterological Endoscopy Society (JGES) guidelines for gastroenterological endoscopy in patients undergoing antithrombotic treatment. METHODS: We retrospectively analyzed 524 patients treated with EST who received DOAC or no antithrombotic drug from May 2016 to August 2019. We investigated the risk factors for bleeding. DOAC was typically discontinued for ≤ 1-day based on the JGES guideline. Although DOAC therapy recommenced the next morning after EST in principle, the duration of DOAC cessation and heparin replacement were determined by the attending physician based on each patient's status. RESULTS: The number of patients on DOAC (DOAC group) and those not on antithrombotic drug (no-drug group) was 42 (8.0%) and 482 (92.0%), respectively. DOAC was discontinued for ≤ 1-day in 17 (40.0%) patients and for > 1-day in 25 (60.0%). Of the 524 patients, 21 (4.0%) had EST bleeding. The bleeding rate was higher in the DOAC group (14.0%) (p = 0.004). Multivariate analysis showed that bleeding occurred more frequently in patients on DOAC (odds ratio [OR] 3.95, 95% confidence interval [CI] 1.37-11.4, p = 0.011), patients with low platelet counts (< 100,000/µl) (OR 6.74, 95% CI 2.1-21.6, p = 0.001), and elderly patients (> 80 years old) (OR 3.36, 95%CI 1.17-9.65, p = 0.024). CONCLUSIONS: DOAC treatment, low platelet count, and old age (> 80 years old) are risk factors for EST bleeding. Although the bleeding incidence increased in patients on DOAC who received antithrombotic therapy according to the JGES guidelines, successful hemostasis was achieved with endoscopy in all cases, and no thrombotic events occurred after cessation of DOAC. Thus, the JGES guidelines are acceptable.

BACKGROUND: Upper gastrointestinal (GI) bleeding is the most important presentation of an aorto-duodenal fistula (ADF). Early diagnosis is difficult, and the disease is associated with high mortality. The present study aimed to examine the clinical and the endoscopic characteristics of ADF in eight patients who presented to our hospital. We also sought to clarify the diagnostic approach towards the disease. METHODS: The present study examined the clinical and the endoscopic/computed tomography (CT) characteristics of ADF in eight patients who were definitively diagnosed with this condition in a 12-year period at our hospital. RESULTS: The patients comprised of five men and three women, with a mean age of 69.8 years. Upper gastrointestinal bleeding was the chief complaint for all the patients. Out of these, two patients presented with shock. The patients' mean haemoglobin at presentation was 7.09 g/dL, and the mean number of blood transfusions was 7.5. All patients had undergone intervention to manage an aortic pathology in the past. As the first investigation, an upper GI endoscopy in 5 and a CT scan in 3 patients were performed. In cases where CT scan was performed first, no definitive diagnosis was obtained, and the diagnosis was confirmed by performing an upper GI endoscopy. In cases where endoscopy was performed first, definitive diagnosis was made in only one case, and the other cases were confirmed by the CT scan. In some cases, tip attachments, converting to long endoscopes, and marking clips were found useful. CONCLUSIONS: In patients who have undergone intervention to manage an aortic pathology and have episodes of upper gastrointestinal bleeding, ADF cannot be definitively diagnosed with only one investigation. In addition, when performing upper GI endoscopy in cases where an ADF is suspected, tip attachment, converting to a long endoscope, and using marking clips can be helpful.

Amyloid light-chain (AL) amyloidosis rarely causes colorectal submucosal hematoma. A 76-year-old man presented with a complaint of bloody stool. An initial colonoscopy revealed ulcerative lesions in the descending colon, leading to a diagnosis of ischemic colitis. One month later, he presented with cardiac failure, suspected cardiac amyloidosis, and underwent a second colonoscopy. Although it revealed multiple ulcerative lesions from the ascending to transverse colon, biopsy samples did not confirm amyloid deposition. He underwent a third colonoscopy 3 weeks later due to recurrent bloody stool. It showed multiple submucosal hematomas from the ascending to descending colon concomitant with ulcerative lesions in the descending colon and multiple elevated lesions in the sigmoid colon. Biopsy samples confirmed amyloid deposition. Using a systemic search, multiple myeloma with AL amyloidosis was diagnosed. Colorectal submucosal or intramural hematomas are conditions usually encountered in trauma, antithrombotic use, or coagulation disorders. Based on our review of the literatures, we identified several differences between colorectal intramural hematoma caused by amyloidosis and those caused by other etiologies. We believe that amyloidosis should be considered when relatively small and multiple colorectal hematomas, not restricted to the sigmoid colon, and with concomitant findings of erosions and ulcers, are observed.

BACKGROUND: Duodenal Brunner's gland hyperplasia (BGH) is a therapeutic target when complications such as bleeding or gastrointestinal obstruction occur or when malignancy cannot be ruled out. Herein, we present a case of large BGH treated with endoscopic mucosal resection (EMR). CASE SUMMARY: An 83-year-old woman presented at our hospital with dizziness. Blood tests revealed severe anemia, esophagogastroduodenoscopy showed a 6.5 cm lesion protruding from the anterior wall of the duodenal bulb, and biopsy revealed the presence of glandular epithelium. Endoscopic ultrasonography (EUS) demonstrated relatively high echogenicity with a cystic component. The muscularis propria was slightly elevated at the base of the lesion. EMR was performed without complications. The formalin-fixed lesion size was 6 cm × 3.5 cm × 3 cm, showing nodular proliferation of non-dysplastic Brunner's glands compartmentalized by fibrous septa, confirming the diagnosis of BGH. Reports of EMR or hot snare polypectomy are rare for duodenal BGH > 6 cm. In this case, the choice of EMR was made by obtaining information on the base of the lesion as well as on the internal characteristics through EUS. CONCLUSION: Large duodenal lesions with good endoscopic maneuverability and no evident muscular layer involvement on EUS may be resectable via EMR.
RESUMEN
BACKGROUND: Esophageal variceal bleeding is a severe complication associated with liver cirrhosis and typically necessitates endoscopic hemostasis. The current standard treatment is endoscopic variceal ligation (EVL), and Western guidelines recommend antibiotic prophylaxis following hemostasis. However, given the improvements in prognosis for variceal bleeding due to advancements in the management of bleeding and treatments of liver cirrhosis and the global concerns regarding the emergence of multidrug-resistant bacteria, there is a need to reassess the use of routine antibiotic prophylaxis after hemostasis. AIM: To evaluate the effectiveness of antibiotic prophylaxis in patients treated for EVL. METHODS: We conducted a 13-year observational study using the Tokushukai medical database across 46 hospitals. Patients were divided into the prophylaxis group (received antibiotics on admission or the next day) and the non-prophylaxis group (did not receive antibiotics within one day of admission). The primary outcome was composed of 6-wk mortality, 4-wk rebleeding, and 4-wk spontaneous bacterial peritonitis (SBP). The secondary outcomes were each individual result and in-hospital mortality. A logistic regression with inverse probability of treatment weighting was used. A subgroup analysis was conducted based on the Child-Pugh classification to determine its influence on the primary outcome measures, while sensitivity analyses for antibiotic type and duration were also performed. RESULTS: Among 980 patients, 790 were included (prophylaxis: 232, non-prophylaxis: 558). Most patients were males under the age of 65 years with a median Child-Pugh score of 8. The composite primary outcomes occurred in 11.2% of patients in the prophylaxis group and 9.5% in the non-prophylaxis group. No significant differences in outcomes were observed between the groups (adjusted odds ratio, 1.11; 95% confidence interval, 0.61-1.99; P = 0.74). Individual outcomes such as 6-wk mortality, 4-wk rebleeding, 4-wk onset of SBP, and in-hospital mortality were not significantly different between the groups. The primary outcome did not differ between the Child-Pugh subgroups. Similar results were observed in the sensitivity analyses. CONCLUSION: No significant benefit to antibiotic prophylaxis for esophageal variceal bleeding treated with EVL was detected in this study. Global reassessment of routine antibiotic prophylaxis is imperative.

Introduction: Cold snare polypectomy (CSP) is a procedure with a low risk of complications. Here, we present our experience of a rare case of submucosal abscess following CSP in an immunosuppressed patient. Case Presentation: Seventy-eight-year-old man underwent CSP, developing a fever, chills, and right lower abdominal pain 8 days later. Ultrasound and computed tomography revealed wall thickening of the ascending colon, presenting as whitening and thickening of the same region, and excretion of pus was observed after biopsy. The diagnosis was made as phlegmonous colitis, for which antibiotic therapy was commenced. The patient was diagnosed with chronic myelomonocytic leukemia (CMML) during admission. We considered the following reasons as possible causes of infectious complications after CSP: (1) the patient had a highly immunosuppressed state with comorbidities such as CMML as well as diabetes mellitus and (2) disruption of the mucosal barrier occurred during endoscopic resection. Conclusion: Although CSP is generally considered safe, our case highlights the potential for serious complications in immunosuppressed patients. Therefore, the decision to perform CSP in such patients should be made with caution to avoid unnecessary interventions. In instances where treatment is essential, thorough bowel preparation and prophylactic antibiotic use may be necessary to mitigate the risks.
RESUMEN
BACKGROUND: Short-term treatment of acute cholangitis is sufficient for cure compared with the standard treatment duration. Whether this short-course antimicrobial therapy is effective in patients with acute cholangitis with positive blood cultures has not been fully investigated. This study assessed whether patients with acute cholangitis could achieve successful outcomes with a three-day or shorter antimicrobial treatment period, even with a positive blood culture. METHODS: This single-center retrospective study involved patients with acute cholangitis, defined according to the Tokyo Guidelines 2018 for any cause, who underwent successful biliary drainage and completed a seven-day or shorter antimicrobial treatment. Patients were categorized into six groups based on the duration of antibiotic use (short or standard) after endoscopic retrograde cholangiopancreatography and blood culture findings (positive, negative, or no collection). The primary outcome was the clinical cure rate, defined as no initial presenting symptoms by day 14 after biliary drainage and no recurrence or death by day 30. Secondary outcomes included a three-month recurrence rate and length of hospital stay. RESULTS: In total, 389 cases were selected, and 27 patients (6.9%) undergoing short-course therapy tested positive for blood culture. The clinical cure rate (n=25, 92.6%) in this group was comparable to that in the other groups. For the three-month recurrence rate (n=1, 3.7%) and median hospital stay (six days), this group's outcomes were either better or similar to those of the other groups. CONCLUSIONS: For cases of successful drainage in acute cholangitis, even with positive blood cultures, short-term antibiotic therapy may be appropriate.
RESUMEN
Background and Aim: The appropriate duration of antimicrobial therapy for acute cholangitis (AC) arising from multiple hilar biliary obstructions as opposed to simple obstruction in the extrahepatic bile duct has not been established. This study assessed the efficacy of the duration of antimicrobial treatments in the Tokyo Guidelines 2018 for AC based on the cause and site of obstruction. Methods: This single-center retrospective study involved patients with AC who underwent successful biliary drainage and completed a 7-day or shorter antimicrobial treatment. Patients were categorized into three groups: Group 1, bile duct stone or benign obstruction; Group 2, simple biliary obstruction due to malignancy; and Group 3, multiple hilar biliary obstruction due to malignancy. The primary outcome was clinical cure rate, and the secondary outcomes were 3-month recurrence rate and length of hospital stay. Results: A total of 373 patients were selected. Patients in Group 3 were younger or had Charlson Comorbidity Index ≥4, and had fewer positive blood cultures. In Group 3, the clinical cure rate (87.1%) and 3-month recurrence rate (32.3%) were less favorable than those in the other groups. In Group 1, the clinical cure rate was significantly higher (98.1%, P = 0.02) with a much lower 3-month recurrence rate of only 3.4% (P < 0.001) than that in the other groups. The median hospital stay for all groups was 7 days. Conclusion: This study suggests that the outcomes in Group 3 may be worse than those in Groups 1 or 2, regardless of the duration of the antibiotic treatment.
RESUMEN
The standard treatment duration for acute cholangitis (AC) involves a 4-7-day antimicrobial treatment post-biliary drainage; however, recent studies have suggested that a ≤ 2-3 days is sufficient. However, clinical practice frequently depends on body temperature as a criterion for discontinuing antimicrobial treatment. Therefore, in this study, we assessed whether patients with AC can achieve successful outcomes with a ≤ 7-day antimicrobial treatment, even with a fever, assuming the infection source is effectively controlled. We conducted a single-center retrospective study involving patients with AC, defined following the Tokyo Guidelines 2018 for any cause, who underwent successful biliary drainage and completed a ≤ 7-day antimicrobial treatment. Patients were categorized into the febrile and afebrile groups based on their body temperature within 24 h before completing antimicrobial treatment. The primary outcome was the clinical cure rate, defined as no initial presenting symptoms by day 14 post-biliary drainage without recurrence or death by day 30. The secondary outcome was a 3-month recurrence rate. Logistic regression with inverse probability of treatment weighting was used. Overall, 408 patients were selected, among whom 40 (9.8%) were febrile. The two groups showed no significant differences in the clinical cure and 3-month recurrence rates. Notably, the subgroups limited to patients with a ≤ 3-day antibiotic treatment duration also showed no differences in these outcomes. Therefore, our results suggest that discontinuing antibiotics within the initially planned treatment period was sufficient for successful drainage cases of AC, regardless of the patient's fever status during the 24 h leading up to termination.

BACKGROUND: Nodular gastritis (NG) is characterized by marked antral lymphoid follicle formation, and is a strong risk factor for diffuse-type gastric cancer in adults. However, it is unknown whether aberrant DNA methylation, which is induced by atrophic gastritis (AG) and is a risk for gastric cancer, is induced by NG. Here, we analyzed methylation induction by NG. METHODS: Gastric mucosal samples were obtained from non-cancerous antral tissues of 16 NG and 20 AG patients with gastric cancer and 5 NG and 6 AG patients without, all age- and gender-matched. Genome-wide methylation analysis and expression analysis were conducted by a BeadChip array and RNA-sequencing, respectively. RESULTS: Clustering analysis of non-cancerous antral tissues of NG and AG patients with gastric cancer was conducted using methylation levels of 585 promoter CpG islands (CGIs) of methylation-resistant genes, and a large fraction of NG samples formed a cluster with strong methylation induction. Promoter CGIs of CDH1 and DAPK1 tumor-suppressor genes were more methylated in NG than in AG. Notably, methylation levels of these genes were also higher in the antrum of NG patients without cancer. Genes related to lymphoid follicle formation, such as CXCL13/CXCR5 and CXCL12/CXCR4, had higher expression in NG, and genes involved in DNA demethylation TET2 and IDH1, had only half the expression in NG. CONCLUSIONS: Severe aberrant methylation, involving multiple tumor-suppressor genes, was induced in the gastric antrum and body of patients with NG, in accordance with their high gastric cancer risk.

BACKGROUND: Acute esophageal mucosal lesions (AEMLs) are an underrecognized and largely unexplored disease. Endoscopic findings are similar, and a higher percentage of AEML could be misdiagnosed as reflux esophagitis Los Angeles classification grade D (RE-D). These diseases could have different pathologies and require different treatments. AIM: To compare AEML and RE-D to confirm that the two diseases are different from each other and to clarify the clinical features of AEML. METHODS: We selected emergency endoscopic cases of upper gastrointestinal bleeding with circumferential esophageal mucosal injury and classified them into AEML and RE-D groups according to the mucosal injury's shape on the oral side. We examined patient background, blood sampling data, comorbidities at onset, endoscopic characteristics, and outcomes in each group. RESULTS: Among the emergency cases, the AEML and RE-D groups had 105 (3.1%) and 48 (1.4%) cases, respectively. Multiple variables exhibited significantly different results, indicating that these two diseases are distinct. The clinical features of AEML consisted of more comorbidities [risk ratio (RR): 3.10; 95% confidence interval (CI): 1.68-5.71; P < 0.001] and less endoscopic hemostasis compared with RE-D (RR: 0.25; 95%CI: 0.10-0.63; P < 0.001). Mortality during hospitalization was higher in the AEML group (RR: 3.43; 95%CI: 0.82-14.40; P = 0.094), and stenosis developed only in the AEML group. CONCLUSION: AEML and RE-D were clearly distinct diseases with different clinical features. AEML may be more common than assumed, and the potential for its presence should be taken into account in cases of upper gastrointestinal bleeding with comorbidities.
RESUMEN
An 87-year-old man with dysphagia presented to our hospital. He was diagnosed with autoimmune gastritis (AIG) with severe atrophy and hypergastrinemia. The patient was positive for parietal cell antibody (PCA) and anti-intrinsic factor antibody (IFA), without evidence of H. pylori infection. A flat elevated tumor was detected in the middle corpus, and therapeutic endoscopic submucosal dissection was performed. Histopathological examination revealed atypical cells mimicking the fundic glands, which were positive for pepsinogen-I and partially positive for MUC6 and H + /K + -ATPase, proliferating to the deep layer. The final diagnosis was gastric adenocarcinoma of the fundic gland type (GAFG). AIG is expected to be difficult to develop GAFG because the basal gastric glands are highly atrophic due to the production of PCA. However, some chief cells may remain and could have the potential to develop into malignancy during AIG progression. Therefore, careful observation is required in patients with AIG when considering the occurrence of GAFG.

Chronic ischemic gastritis (CIG) requires early diagnosis and treatment as complications of thromboembolism can be fatal. Although computed tomography (CT) is useful in the diagnosis of CIG, it is difficult to diagnose from a patient's history, endoscopic findings, and tissue biopsy. Identification of the key findings that motivate computed tomography is an important issue. We report a case of CIG diagnosed by endoscopic findings of white patches of mucosa over time. A 63-year-old man presented with epigastric pain. He had a history of repeated gastric ulcers of an undetermined cause. We performed upper endoscopy and observed the appearance of multiple white patches on the gastric mucosa. Central vessel stenosis was considered, and aortic computed tomography revealed complete occlusion of the superior mesenteric artery and stenosis of the celiac artery. We carried out a surgical bypass and found no postoperative endoscopic mucosal changes or abdominal pain. White patch changes in the gastric mucosa over time during endoscopy may indicate CIG. This finding may help in the future diagnosis of CIG.
