[Clinical Management of Non-Variceal Upper Gastrointestinal Bleeding].

Non-variceal upper gastrointestinal bleeding (NVUGIB) is defined as bleeding proximal to the ligament of Treitz in the absence of varices. As a common clinical problem, NVUGIB entails a heavy burden on the healthcare system. In addition to endoscopic hemostasis, evaluation and treatment before and after endoscopy are also of critical importance for the clinical management of NVUGIB patients. In recent years, based on the rapid development of endoscopic technology and clinical management of NVUGIB, the research evidence and clinical guidelines have been updated internationally, while some clinical decisions remain controversial. In this article, we mainly reviewed and discussed the current status of NVUGIB patient management before, during, and after endoscopy, aiming to deepen the understanding of the disease for clinicians, and to promote standardized management of patients with NVUGIB.

[Efficacy Analysis of Transcatheter Arterial Embolization in Acute Non-Variceal Upper Gastrointestinal Bleeding].

Objective: To evaluate the safety and effectiveness of transcatheter arterial embolization (TAE) in the treatment of acute non-variceal upper gastrointestinal bleeding (ANVUGIB), and to guide clinical practice and continue to optimize diagnosis and treatment strategies. Methods: This retrospective study included 266 patients who underwent angiography due to ANVUGIB between March 2016 and March 2021. Data on the positive rate of angiography, the technical success rate and clinical success rate of TAE, and the rebleeding rate and the all-cause mortality within 30 days after TAE treatment were collected, and the influencing factors relevant to the above events were analyzed accordingly. Results: All 266 patients completed angiography--the positive rate of angiography was 54.1% (144/266), the total technical success rate was 97.3% (217/223), the clinical success rate was 73.1% (155/212), and the rebleeding rate and all-cause mortality within 30 days were 26.9% (57/212) and 16.1% (35/217), respectively. This study found that shock index>1 ( OR=5.950; 95% CI: 1.481-23.895; P=0.012), computed tomography angiography (CTA) positive result ( OR=6.813; 95% CI: 1.643-28.252; P=0.008) and interval<24 h ( OR=10.530; 95% CI: 2.845-38.976; P<0.001) were independent predictors of positive angiography. Shock index>1 ( OR=2.544; 95% CI: 1.301-4.972; P=0.006) and INR>1.5 ( OR=3.207; 95% CI: 1.381-7.451; P=0.007) were independent risk factors for rebleeding. Patients with postoperative bleeding ( OR=3.174; 95% CI: 1.164-8.654; P=0.024) and patients with rebleeding after embolization ( OR=34.665; 95% CI: 11.471-104.758; P<0.001) had a higher risk of death within 30 days. Conclusion: TAE is safe and effective in the treatment of ANVUGIB. Patients with shock index>1 and positive CTA are more likely to be angiographic positive, and should undergo angiography as early as possible after bleeding. In addition, rebleeding after embolization deserves high attention.

Assessing guideline adherence in patients with non-variceal upper gastrointestinal bleeding receiving antiplatelet and anticoagulant therapy.

Background & aims: Non-variceal upper gastrointestinal bleeding (NVUGIB) occurs frequently and is associated with a significant morbidity and mortality, especially in patients receiving antiplatelet or anticoagulant therapy (APT and ACT, respectively). We aimed to evaluate adherence to guideline recommendations published by European Society of Gastrointestinal Endoscopy (ESGE).Methods: Retrospective analysis of patients with NVUGIB und prior exposition to APT or ACT at a single university hospital between 01 January 2016 and 31 December 2017.Results: 270 patients were identified (70.4% male, median age 72 years). 6/17 (35.3%) patients receiving APT for primary cardiovascular prophylaxis, 39/71 (54.9%) and 35 (49.3%) patients receiving APT for secondary cardiovascular prophylaxis (using strict and liberal definition, respectively) and 13/25 (52%) patients receiving dual antiplatelet therapy (DAPT) were not managed according to current recommendations. Management of ACT for secondary thromboembolic prophylaxis did not follow guideline recommendations in 59/93 (63.4%) and 34/93 (36.6%) patients (using strict and liberal definition, respectively). 23.7% of patients with NVUGIB were exposed to combined APT and ACT for whom no guideline recommendations exist. Mortality for any reason was twice as high in patients who were not managed according to guideline recommendations (18.8% vs. 8% using strict definition, 20.5% vs. 10.2% using liberal definition), which did not remain significant after adjusting for comorbidities, whereas cardiovascular events were observed at similar rates.Conclusion: A significant number of patients with NVUGIB receiving APT or ACT is not managed according to current ESGE guideline recommendations. Strategies to implement these guidelines into daily practice need to be developed.

Impaired activity of daily living is a risk factor for high medical cost in patients of non-variceal upper gastrointestinal bleeding.

BACKGROUND: Non-variceal upper gastrointestinal bleeding (NVUGIB) is still a common and life-threatening disease, thus it would have a big impact on medical care cost. However, little is known about risk factors for increased medical care cost in NVUGIB patients. AIM: The purpose of the study was to clarify predictor of requiring high medical care cost in NVUGIB patients. Patients who underwent endoscopic hemostasis due to NVUGIB between April 2012 and March 2015 were included in this retrospective study. We analyzed the association between patients' background including activity of daily livings (ADL) and high medical care cost using logistic regression model. Medical care cost was calculated in reference to the "Diagnosis Procedure Combination" which is diagnosis-dominant case-mix system in Japan. The cutoff value of high medical care cost was defined as its first quartile. ADL was assessed according to Katz-6 score. We defined impaired ADL patient who revealed Katz-6 score more than 1. RESULTS: A total of 128 consecutive patients were included in this study. Median medical care cost was 5323 USD (IQR 3661-8172 USD). There were 13 patients (10%) in impaired ADL group. In univariate analysis, age and impaired ADL before admission revealed significant association with high cost. Of these, impaired ADL was an only independent risk factor [odds ratio 15.3 (95% CI 2.49-183)] in multivariate analysis. CONCLUSION: Impairment in ADL before admission was an independent predictor for high medical care cost with NVUGIB patients.

[Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding (2018, Hangzhou)].

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is one of the most common medical emergencies worldwide. In 2009, the first edition of "Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding" was published in China. These guidelines were updated in 2015, which aimed to provide the standard diagnosis and management for patients with ANVUGIB. Based on the rapid development of multiple disciplines and latest understanding of ANVUGIB, this new edition of guidelines was therefore released for standardizing the diagnosis and management process of ANVUGIB.

Effectiveness of the polysaccharide hemostatic powder in non-variceal upper gastrointestinal bleeding: Using propensity score matching.

BACKGROUND AND AIM: Recently, the application of hemostatic powder to the bleeding site has been used to treat active upper gastrointestinal bleeding (UGIB). We aimed to assess the effectiveness of the polysaccharide hemostatic powder (PHP) in patients with non-variceal UGIB. METHODS: We reviewed prospectively collected 40 patients with UGIB treated with PHP therapy between April 2016 and January 2017 (PHP group) and 303 patients with UGIB treated with conventional therapy between April 2012 and October 2014 (conventional therapy group). We compared the rate of successful hemostasis and the rebleeding between the two groups after as well as before propensity score matching using the Glasgow-Blatchford score and Forrest classification. RESULTS: Thirty patients treated with the PHP and 60 patients treated with conventional therapy were included in the matched groups. Baseline patient characteristics including comorbidities, vital signs, and bleeding scores were similar in the matched groups. The rate of immediate hemostasis and 7-day and 30-day rebleeding were also similar in the two groups before and after matching. In the subgroup analysis, no significant differences in immediate hemostasis or rebleeding rate were noted between PHP in monotherapy and PHP combined with a conventional hemostatic method. At 30 days after the therapy, there were no significant PHP-related complications or mortality. CONCLUSIONS: Given its safety, the PHP proved feasible for endoscopic treatment of UGIB, having similar effectiveness as that of conventional therapy. The PHP may become a promising hemostatic method for non-variceal UGIB.

Endoscopic hemostasis for peptic ulcer bleeding: systematic review and meta-analyses of randomized controlled trials.

BACKGROUND: Peptic ulcer represents the most common cause of upper gastrointestinal bleeding. Endoscopic therapy can reduce the risks of rebleeding, continued bleeding, need for surgery, and mortality. The objective of this review is to compare the different modalities of endoscopic therapy. METHODS: Studies were identified by searching electronic databases MEDLINE, Embase, Cochrane, LILACS, DARE, and CINAHL. We selected randomized clinical trials that assessed contemporary endoscopic hemostatic techniques. The outcomes evaluated were: initial hemostasis, rebleeding rate, need for surgery, and mortality. The possibility of publication bias was evaluated by funnel plots. An additional analysis was made, including only the higher-quality trials. RESULTS: Twenty-eight trials involving 2988 patients were evaluated. Injection therapy alone was inferior to injection therapy with hemoclip and with thermal coagulation when evaluating rebleeding and the need for emergency surgery. Hemoclip was superior to injection therapy in terms of rebleeding; there were no statistically significant differences between hemoclip alone and hemoclip with injection therapy. There was considerable heterogeneity in the comparisons between hemoclip and thermal coagulation. There were no statistically significant differences between thermal coagulation and injection therapy, though their combination was superior, in terms of rebleeding, to thermal coagulation alone. CONCLUSIONS: Injection therapy should not be used alone. Hemoclip is superior to injection therapy, and combining hemoclip with an injectate does not improve hemostatic efficacy above hemoclip alone. Thermal coagulation has similar efficacy as injection therapy; combining these appears to be superior to thermal coagulation alone. Therefore, we recommend the application of hemoclips or the combined use of injection therapy with thermal coagulation for the treatment of peptic ulcer bleeding.

Out-of-hours endoscopy for non-variceal upper gastrointestinal bleeding.

BACKGROUND: Most countries lack a well-coordinated approach to out-of-hours endoscopy. Economic constraints and lack of resources have been identified as important barriers. OBJECTIVE: To assess the performance evaluation of an out-of-hours emergency endoscopy model of care. DESIGN: During a 3 year period (January 2010 to December 2012), data from consecutive outpatients (n = 332) with non-variceal acute upper gastrointestinal bleeding admitted or transferred to a single referral hospital were prospectively collected. RESULTS: 34% (n = 113) were direct admissions whereas 66% (n = 219) were transferred from other hospitals. Median time to upper endoscopy esophagogastroduodenoscopy (EGD) was 6 h and 7.7 h for direct admissions and transferred, respectively. EGD was performed within 24 h in 90% of the patients. Rebleeding, in-hospital mortality, 30 day mortality and need for surgery were respectively 9.8%, 5.8%, 7.4%, and 6.6% and were not significantly different between the two groups. Age, malignancy, and moderate to high clinical Rockall risk score were independent predictors of in-hospital mortality in both groups. Age remained as an important predictor of main outcomes in transferred patients, while comorbidities differed according to admission status and predictable outcomes. CONCLUSION: This gastroenterology emergency model improved access and equity to out-of-hours endoscopy in an effective, safe, and timely way, recognized by the rates and the homogeneity observed in the outcomes, between transferred patients and direct admissions.

Risk of peptic ulcer bleeding associated with Helicobacter pylori infection, nonsteroidal anti-inflammatory drugs, low-dose aspirin, and antihypertensive drugs: a case-control study.

BACKGROUND AND AIM: The associations between antithrombotic or antihypertensive drugs and peptic ulcer bleeding (PUB) remain unknown, particularly in Asia, where Helicobacter pylori infection is prevalent. This study aims to evaluate the risks of PUB from antithrombotic drugs, angiotensin II receptor blockers (ARBs), angiotensin-converting enzyme (ACE) inhibitors, calcium channel blockers, α-blockers, and ß-blockers. METHODS: This prospective hospital-based case-control study included 230 patients with endoscopically verified PUB and 920 age and sex-matched controls (1:4) without bleeding on screening endoscopy. Adjusted odds ratios (AOR) for the risk of PUB were determined by conditional logistic regression analysis. RESULTS: In multivariate analysis, alcohol consumption (AOR, 2.2; P < 0.001), history of peptic ulcer (AOR, 4.8; P < 0.001), H. pylori infection (AOR, 2.1; P < 0.001), comorbidity index (AOR, 1.1; P = 0.089), nonsteroidal anti-inflammatory drugs (NSAIDs) (AOR, 2.0; P = 0.025), and low-dose aspirin (AOR, 2.8; P = 0.003) increased the risk of PUB, whereas H. pylori eradication (AOR, 0.03; P < 0.001), proton pump inhibitors (PPIs) (AOR, 0.1; P < 0.001), and histamine 2-receptor antagonists (H2RA) (AOR, 0.1; P < 0.001) reduced it. No significant interactions were observed between H. pylori infection and NSAIDs use for PUB (P = 0.913). ARBs (P = 0.564), ACE inhibitors (P = 0.213), calcium channel blockers (P = 0.215), α-blockers (P = 0.810), and ß-blockers (P = 0.864) were not associated with PUB. CONCLUSION: We found that alcohol consumption, history of peptic ulcer, H. pylori infection, NSAIDs use, and low-dose aspirin use were independent risk factors for PUB, whereas H. pylori-eradication, PPIs use, and H2RA use reduced its risk. Interactions between H. pylori and NSAIDs use in PUB were not observed. No antihypertensive drug was associated with PUB.

[Incidence and predictive factors of iron deficiency anemia after acute non-variceal upper gastrointestinal bleeding without portal hypertension]. / Incidencia y factores predictivos de anemia ferropénica tras una hemorragia digestiva alta no asociada a hipertensión portal.

INTRODUCTION: There are few studies on iron deficiency anemia (IDA) after non-variceal acute upper gastrointestinal bleeding (UGIB) in patients without portal hypertension. OBJECTIVES: To define the incidence of IDA after UGIB, to characterize the predictive factors for IDA and to design algorithms that could help physicians identify those patients who could benefit from iron therapy. MATERIAL AND METHOD: We registered 391 patients with UGIB between April 2007 and May 2009. Patients with portal hypertension and those with clinical or/and biological conditions that could affect the ferrokinetic pattern were excluded. Blood analyses were performed, including ferric parameters upon admission, on the 5th day, and on the 30th day after the hemorrhage episode. We used a multiple logistic regression model and a classification and regression tree model. RESULTS: A total of 124 patients were included, of which 76 (61.3%) developed IDA 30 days after UGIB. The predictive variables were age >75 years (P=.037; OR 3.9; 95% CI: 1.3-11.6), initial urea level >80mg/dL (P=.027; OR 2.9; 95% CI: 1.1-7.6), initial ferritin level ≤65ng/dL (P=.002; OR 7.6; 95% CI: 2.9-18.5), initial hemoglobin level ≤100g/L (P=.003; OR 3.2; 95% CI: 1.3-8.0), hemoglobin level on the 5th day ≤100g/L (P<.001; OR 14.9; 95% CI: 3.6-61.1) and the value of the transferrin saturation index on the 5th day <10% (p<0.001; OR 7.2; 95% CI: 2.6-20.3). CONCLUSIONS: Most patients with UGIB developed IDA 30 days after the episode. Identification of the predictive factors for IDA may help to establish guidelines for the administration of iron therapy.

Upper gastrointestinal bleeding in hospital inpatients: the role of antithrombotic drugs.

BACKGROUND: Critically ill patients are considered to be most at risk from developing non-variceal upper gastrointestinal bleeding (NVGIB) while in hospital. The increasing prescription of low-dose aspirin and other antithrombotic drugs for protection against thromboembolism to many patients admitted to hospital may increase the vulnerability of a wider group to NVGIB. OBJECTIVE: This study compares two groups of patients with NVGIB: group I, inpatients cared for outside the intensive care unit; and group II, patients admitted with this condition, while considering the use of antithrombotic drugs. METHODS: We identified all patients who developed NVGIB in the two calendar years between 2008 and 2009 and compared group I with group II while taking into account their clinical details including Rockall scores and drug usage. RESULTS: Compared with group II (n=274), group I (n=96) were older (median age of 77 years vs 68; p<0.001), had fewer males (45.8% vs 60.6%; p=0.016), higher prevalence of cardiovascular disease (52.1% vs 29.2%; p<0.001), more patients with complete Rockall score ≥ 3 (84.4% vs 66.7%; p=0.001) and more patients treated with aspirin or other antithrombotic drugs (64.6% vs 44.5%; p=0.001). After adjustment for age and sex, group I were still significantly more likely to be taking antithrombotic drugs than group II (OR (95% CIs), 2.15 (1.25 to 3.68); p=0.006). The endoscopic abnormalities in more than 80% of patients included erosive oesophagitis, gastric or duodenal ulcers or erosions. CONCLUSIONS: Subjects who develop NVGIB as inpatients have higher Rockall scores are mainly older females with cardiovascular disease and using antithrombotic drugs. Secondary care clinicians should be mindful of this at-risk group of patients and consider giving them prophylactic antiulcer therapy.

Improved outcomes in patients with non-variceal upper gastrointestinal bleeding while undergoing antithrombotic therapy: A propensity score matching analysis.

BACKGROUND: This study sought to examine the effect of antithrombotic use on clinical outcomes in non-variceal upper gastrointestinal bleeding (UGIB). METHODS: Patients consecutively diagnosed with non-variceal UGIB between February 2019 and September 2020 were divided into two groups based on their antithrombotic use: users and non-users. Using propensity score matching (PSM) and multivariable regression analyses, the impact of antithrombotic use prior to UGIB presentation on clinical outcomes was examined. RESULTS: In the entire cohort, there were 210 and 260 patients in the antithrombotic user and non-user groups, respectively. Using PSM analysis with seven covariates, two matched groups of 157 patients were created at a 1:1 ratio. In the matched cohort, despite their longer hospital stays and a higher rate of intensive care unit admissions, the patients in the user group had lower 30- and 90-day mortality rates (4.5% vs. 14.0 %; p = 0.003 and 8.9% vs. 18.5 %; p = 0.014, respectively). In the entire cohort, multivariable analyses adjusted for confounding factors revealed that antithrombotic use was associated with lower risks of in-hospital (adjusted OR: 0.437; 95 % CI: 0.191-0.999), 30-day (adjusted OR: 0.261; 95 % CI: 0.099-0.689), and 90-day (adjusted OR: 0.386; 95 % CI: 0.182-0.821) mortality. CONCLUSION: Antithrombotic use prior to UGIB presentation was found to be an independent protective factor for all-cause mortality.

Value of multidetector computed tomography angiography in severe non-variceal upper gastrointestinal bleeding: a retrospective study in a referral bleeding unit.

BACKGROUND: Non-variceal upper gastrointestinal bleeding is a common gastroenterological emergency associated with significant morbidity and mortality. Upper gastrointestinal endoscopy is currently recommended as the gold standard modality for both diagnosis and treatment. As historically played a limited role in the diagnosis of acute non-variceal upper gastrointestinal bleeding, multidetector-row computed tomography angiography is emerging as a promising tool in the diagnosis of non-variceal upper gastrointestinal bleeding, especially for severe cases. However, to date, evidence concerning the role of multidetector-row computed tomography angiography in the non-variceal upper gastrointestinal bleeding diagnosis is still lacking. AIM: The purpose of this study was to retrospectively investigate the diagnostic performance of emergent multidetector-row computed tomography angiography performed prior to any diagnostic modality or following urgent upper endoscopy to identify the status, the site, and the underlying etiology of severe non-variceal upper gastrointestinal bleeding. METHODS: Institutional databases were reviewed in order to identify severe acute non-variceal upper gastrointestinal bleeding patients who were admitted to our bleeding unit and were referred for emergent multidetector-row computed tomography angiography prior to any hemostatic treatment (< 3 h) or following (< 3 h) endoscopy, between December 2019 and October 2022. The study aim was to evaluate the diagnostic performance of multidetector-row computed tomography angiography to detect the status, the site, and the etiology of severe non-variceal upper gastrointestinal bleeding with endoscopy, digital subtraction angiography, surgery, pathology, or a combination of them as reference standards. RESULTS: A total of 68 patients (38 men, median age 69 years [range 25-96]) were enrolled. The overall multidetector-row computed tomography angiography sensitivity, specificity, and accuracy to diagnose bleeding status were 77.8% (95% CI: 65.5-87.3), 40% (95% CI: 5.3-85.3), and 75% (95% CI: 63.0-84.7), respectively. Finally, the overall multidetector-row computed tomography angiography sensitivity to identify the bleeding site and the bleeding etiology were 92.4% (95% CI: 83.2-97.5) and 79% (95% CI: 66.8-88.3), respectively. CONCLUSION: Although esophagogastroduodenoscopy is the mainstay in the diagnosis and treatment of most non-variceal upper gastrointestinal bleeding cases, multidetector-row computed tomography angiography seems to be a feasible and effective modality in detecting the site, the status, and the etiology of severe acute non-variceal upper gastrointestinal bleeding. It may play a crucial role in the management of selected cases of non-variceal upper gastrointestinal bleeding, especially those clinically severe and/or secondary to rare and extraordinary rare sources, effectively guiding timing and type of treatment. However, further large prospective studies are needed to clarify the role of multidetector-row computed tomography angiography in the diagnostic process of acute non-variceal upper gastrointestinal bleeding.

Validating the CHAMPS Score: A Novel and Reliable Prognostic Score of Non-Variceal Upper Gastrointestinal Bleeding.

Introduction: The Charlson Comorbidity Index ≥2, in-Hospital onset, Albumin <2.5 g/dL, altered Mental status, Eastern Cooperative Oncology Group Performance status ≥2, Steroid use (CHAMPS) score is a novel and promising prognostic tool. We present an initial external validation of the CHAMPS score for predicting mortality in acute nonvariceal upper gastrointestinal bleeding (NVUGIB) across multiple clinical outcomes. Methods: A prospective cohort study was conducted on adult patients with NVUGIB admitted to the Department of Gastroenterology between November 2022 and June 2023. The CHAMPS score performance in predicting in-hospital outcomes was evaluated by employing area under the receiver operating characteristic (AUROC) curves, followed by a comparative analysis with five pre-existing scores. Results: A total of 140 patients were included in the study. The CHAMPS score showed its highest performance in predicting mortality rates (AUROC = 0.89), significantly outperforming the Glasgow-Blatchford Bleeding Score (GBS) as well as the Albumin level <3.0 mg/dL, International normalized ratio >1.5, altered Mental status, Systolic blood pressure ≤90 mmHg, and age >65 years (AIMS65) score (AUROC = 0.72 and 0.71, respectively; all p < 0.05). Subgroup analysis for bleeding-related and non-bleeding-related mortality further confirmed the robust predictive capability of the CHAMPS score (AUROC = 0.88 and 0.87, respectively). The CHAMPS score failed to predict rebleeding and intervention reliably, exhibiting AUROC values of 0.43 and 0.55, respectively. The optimal CHAMPS score cutoff value for predicting mortality was 3 points, achieving 100% sensitivity and 71.2% specificity. In the low-risk category defined by both CHAMPS and GBS scores, mortality and rebleeding rates were 0%. However, within the CHAMPS score-based low-risk group, 58.8% required intervention, contrasting with a 0% intervention rate for the GBS score-based low-risk group (GBS score ≤1). Conclusion: The CHAMPS score consistently demonstrated a robust predictive performance for mortality (AUROC > 0.8), facilitating the identification of high-risk patients requiring aggressive treatment and low-risk patients in need of localized treatment or safe discharge after successful bleeding control.

Predictive utility of the Rockall scoring system in patients suffering from acute nonvariceal upper gastrointestinal hemorrhage.

BACKGROUND: Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) represents a significant clinical challenge due to its unpredictability and potentially severe outcomes. The Rockall risk score has emerged as a critical tool for prognostic assessment in patients with ANVUGIB, aiding in the prediction of rebleeding and mortality. However, its applicability and accuracy in the Chinese population remain understudied. AIM: To assess the prognostic value of the Rockall risk score in a Chinese cohort of patients with ANVUGIB. METHODS: A retrospective analysis of 168 ANVUGIB patients' medical records was conducted. The study employed statistical tests, including the t-test, χ 2 test, spearman correlation, and receiver operating characteristic (ROC) analysis, to assess the relationship between the Rockall score and clinical outcomes, specifically focusing on rebleeding events within 3 months post-assessment. RESULTS: Significant associations were found between the Rockall score and various clinical outcomes. High Rockall scores were significantly associated with rebleeding events (r = 0.735, R 2 = 0.541, P < 0.001) and strongly positively correlated with adverse outcomes. Low hemoglobin levels (t = 2.843, P = 0.005), high international normalized ratio (t = 3.710, P < 0.001), active bleeding during endoscopy (χ 2 = 7.950, P = 0.005), large ulcer size (t = 6.348, P < 0.001), and requiring blood transfusion (χ 2 = 6.381, P = 0.012) were all significantly associated with rebleeding events. Furthermore, differences in treatment and management strategies were identified between patients with and without rebleeding events. ROC analysis indicated the excellent discriminative power (sensitivity: 0.914; specificity: 0.816; area under the curve: 0.933; Youden index: 0.730) of the Rockall score in predicting rebleeding events within 3 months. CONCLUSION: This study provides valuable insights into the prognostic value of the Rockall risk score for ANVUGIB in the Chinese population. The results underscore the potential of the Rockall score as an effective tool for risk stratification and prognostication, with implications for guiding risk-appropriate management strategies and optimizing care for patients with ANVUGIB.

Racial Differences in Non-variceal Upper Gastrointestinal (GI) Bleeding: A Nationwide Study.

Background and aims Knowledge about the impact of race on non-variceal upper GI bleeding (NVUGIB) is limited. This study explored the racial differences in the etiology and outcome of NVUGIB. Methods We conducted a study from 2009 to 2014 using the Nationwide Inpatient Sample (NIS) database. NIS is the largest publicly available all-payer inpatient database in the USA with more than seven million hospital stays each year. The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes for NVUGIB, esophagogastroduodenoscopy (EGD) and demographics were obtained. The outcomes of interest were in-hospital mortality, hospital length of stay (HLOS), total hospital charges, admission to the intensive care unit (ICU), and patient disposition. Analysis was conducted using Chi-square tests and Tukey multiple comparisons between groups. Results Among 1,082,516 patients with NVUGIB, African American and Native Americans had the highest proportions of hemorrhagic gastritis/duodenitis (8.2% and 4.2%, respectively) and Mallory-Weiss bleeding (10.4% and 5.4%, respectively; p<0.01). African Americans were less likely to get an EGD done within 24 hours of admission compared to Whites and Latinxs (45.9% vs 50.1% and 50.4%, respectively; p<0.001). In-hospital mortality was similar among African Americans, Latinxs, and Whites (5.8% vs 5.6% vs 5.9%, respectively; p=0.175). Asian/Pacific Islanders and African Americans were more likely to be admitted to the ICU (9.6% and 9.0%, respectively; p<0.001). Moreover, African Americans had a longer HLOS compared to Latinxs and Whites (7.5 vs 6.5 and 6.4 days, respectively; p<0.001). Conversely, Asian/Pacific Islanders and Latinx incurred the highest hospital total charges compared to African Americans and Whites ($81,821 and $69,267 vs $61,484 and $53,767, respectively; p<0.001). Conclusion African Americans are less likely to receive EGD within 24 hours of admission and are more likely to be admitted to the ICU with prolonged hospital lengths of stay. Latinxs are more likely to be uninsured and incur the highest hospital costs.

Importance of risk assessment, endoscopic hemostasis, and recent advancements in the management of acute non-variceal upper gastrointestinal bleeding.

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is a common medical emergency in clinical practice. While the incidence has significantly reduced, the mortality rates have not undergone a similar reduction in the last few decades, thus presenting a significant challenge. This editorial outlines the key causes and risk factors of ANVUGIB and explores the current standards and recent updates in risk assessment scoring systems for predicting mortality and endoscopic treatments for achieving hemostasis. Since ANUVGIB predominantly affects the elderly population, the impact of comorbidities may be responsible for the poor outcomes. A thorough drug history is important due to the increasing use of antiplatelet agents and anticoagulants in the elderly. Early risk stratification plays a crucial role in deciding the line of management and predicting mortality. Emerging scoring systems such as the ABC (age, blood tests, co-morbidities) score show promise in predicting mortality and guiding clinical decisions. While conventional endoscopic therapies remain cornerstone approaches, novel techniques like hemostatic powders and over-the-scope clips offer promising alternatives, particularly in cases refractory to traditional modalities. By integrating validated scoring systems and leveraging novel therapeutic modalities, clinicians can enhance patient care and mitigate the substantial morbidity and mortality associated with ANVUGIB.

Hemospray Versus Conventional Therapy for Non-variceal Upper Gastrointestinal Bleeding: A Systematic Review and Meta-Analysis.

Hemospray (TC-325; Cook Medical, Winston-Salem, NC) has been used effectively in hemostasis in non-variceal upper gastrointestinal (GI) bleeding. Current guidelines suggest using Hemospray as a temporizing measure or adjunct technique. This systematic review and meta-analysis aimed to evaluate the efficacy and safety of Hemospray as a modality for primary hemostasis. We searched MEDLINE, CENTRAL, and CINAHL (Cumulative Index of Nursing and Allied Health Literature) databases from inception to August 1, 2022. Three independent reviewers performed a comprehensive review of all original articles describing the application of Hemospray as the primary method of hemostasis in non-variceal upper GI bleeding patients. Three reviewers independently reviewed and abstracted data and assessed study quality using the Cochrane risk of bias tool. Primary outcomes were (1) primary hemostasis rate, (2) rebleeding rate until hospital discharge or death, (3) need for surgery, and (4) overall mortality rate. Of the 211 studies identified, 146 underwent title and abstract review, and four were included in the systematic review. Pooled results from 303 patients showed that compared to standard of care, Hemospray has significantly higher odds of primary hemostasis (OR: 3.48, 95% CI: 1.09-11.18, p = 0.04). There was no statistically significant difference in terms of rebleeding rates (OR: 0.79, 95% CI: 0.24-2.55, p = 0.69), need for surgery (OR: 1.62, 95% CI: 0.35-7.41, p = 0.54), or overall mortality (OR: 1.08, 95% CI: 0.56-2.08, p = 0.83). This systematic review and meta-analysis prove that Hemospray is a better modality of primary hemostasis in non-variceal upper GI bleeding when used as a primary method. At the same time, there is no significant difference in complications, including rebleeding, need for surgical intervention, and all-cause mortality.

Retrospective analysis of risk factors for non-variceal upper gastrointestinal bleeding and construction of a nomogram prediction model.

AIM: By analyzing the clinical data of patients with non-variceal upper gastrointestinal bleeding (NVUGIB), the independent risk factors for NVUGIB were found, and a risk prediction model was initially constructed. METHODS: This retrospective analysis collected patients hospitalized in Laizhou City People's Hospital from January 2020 to January 2022. According to whether the patients had NVUGIB during hospitalization, they were divided into a bleeding group of 173 cases and a control group of 121 cases. We collected the medical records of the two groups, including general conditions, disease conditions, medication conditions, and laboratory test indicators. The independent risk factors of NVUGIB were screened by univariate and multivariate logistic regression analysis, and a prediction model was initially constructed. The nomogram was developed using R language. the establishment of a regression equation model was based on the above risk factors: logit (P) = -8.320 + 0.436 * history of peptic ulcer + Helicobacter pylori infection * 0.522 + use of anticoagulant and antiplatelet drugs * 0.881 + 0.583 * increased leukocyte count + prolonged international normalized ratio (INR) * 0.651 + hypoproteinemia * 0.535. By using receiver operating characteristic curves, area under curve and Hosmer-Lemeshow test, the discrimination and calibration of the model was evaluated, and a calibration curves were plotted. RESULTS: Univariate and multivariate regression analysis identified that history of peptic ulcer, Helicobacter pylori infection, use of anticoagulant and antiplatelet drugs, increased leukocyte count, prolonged INR and hypoproteinemia were risk factors for NVUGIB. Those risk factors were used to construct a clinical predictive nomogram. The calibration curves for NVUGIB risk revealed excellent accuracy of the predictive nomogram model. The unadjusted C-index was 0.773 [95% CI, 0.515-0.894]. The area under the curve was 0.793982. Decision curve analysis showed that the predictive model could be applied clinically when the threshold probability was 20 to 60%. CONCLUSIONS: A history of peptic ulcer, Helicobacter pylori infection, use of anticoagulant and antiplatelet drugs, increased leukocyte count, prolonged INR, and hypoproteinemia may be independent risk factors for NVUGIB. Furthermore, this study initially established a risk prediction model for NVUGIB and developed a nomogram. It was verified that the model had good differentiation ability and consistency, andcould provide a practical reference for clinical work.
