Epidemiology of acute upper gastrointestinal bleeding

The impact of inter-hospital transfer on outcomes in lower gastrointestinal bleeding: a retrospective cohort analysis

BACKGROUND

This study investigates the role of interhospital transfer (IHT) in lower gastrointestinal bleeding (LGIB) management and its impact on patient outcomes, focusing on mortality rates, complication occurrences, procedural performance, and resource utilization in patients diagnosed with LGIB.

METHODS

This retrospective cohort study used data from the National Inpatient Sample database from 2017 to 2020. It included adult patients diagnosed with LGIB, assessing the impact of IHT on outcomes such as mortality, complication rates, procedural performance, and resource utilization. Adjusted odds ratios (AOR) and adjusted mean differences (AMD) were used to evaluate these impacts.

RESULTS

A total of 393,495 LGIB patients were analyzed, with 31,565 (8.02%) undergoing interhospital transfer. Transferred patients exhibited significantly higher inpatient mortality (AOR 1.96, P < 0.01). They also faced increased risks of acute kidney injury (AOR 1.32, P < 0.01), septic shock (AOR 2.11, P < 0.01), and intensive care unit admission (AOR: 2.61, P < 0.01). These patients were more likely to undergo interventional radiology-guided embolization (AOR 2.68, P < 0.01) and showed variations in colonoscopy procedures. Resource utilization was also higher among transferred patients, with an increased mean length of hospital stay by 4.37 days (P < 0.01) and higher hospitalization charges (mean difference $61,239, P < 0.01).

CONCLUSION

Interhospital transfer in LGIB patients is associated with increased mortality, greater resource utilization, and the need for more specialized procedural interventions. Enhanced clinical vigilance and tailored resource allocation for transferred LGIB patients are necessary. Future research should optimize care strategies for these high-risk patients.

The efficacy and comparison of upper gastrointestinal bleeding risk scoring systems on predicting clinical outcomes among emergency unit patients

BACKGROUND

Gastrointestinal bleeding is a significant cause of morbidity and mortality among emergency unit patients. Several scoring systems are verified for predicting hospitalization and mortality such as Glasgow Blatchford Bleeding Score (GBS), AIMS65 score, Rockall score (RS), and International Bleeding Risk Score (INBS; ABC score). The aim of this study is to evaluate the efficacy and predictive value of these scoring systems.

METHODS

Adult emergency unit patients with gastrointestinal bleeding were retrospectively enrolled. The age, gender, complaints at admission, vitals and examination results, laboratory findings, outcomes, blood transfusion status, and endoscopic interventions were all reported, and GBS, AIMS65, RS, and INBS (ABC) scores were calculated individually for all enrollies.

RESULTS

A total of 311 patients were included. The median age of participants was 70 years (IQR (25-75%): 59-81), and 202 (65%) of them were male. The efficacy of all four scoring systems (GBS, AIMS65, RS, and INBS (ABC)) in predicting hospitalization, need of blood transfusion, determination of high- and low-risk patients, and mortality was found to be statistically significant (p < 0.05 for all). ROC-AUC analysis was revealed that while GBS is the most beneficial in predicting hospitalization, INBS (ABC) has the best predictive value on mortality. Besides, the only scoring model with predictive value in determining the need for endoscopic intervention was RS (p < 0.05).

CONCLUSION

The present study showed that, among adult emergency unit patients with gastrointestinal bleeding, GBS, AIMS65, RS, and INBS (ABC) scores could successfully predict hospitalization, need of blood transfusion, determination of high- and low-risk patients, and mortality. However, the only scoring system that could be used to determine the need of endoscopic intervention is RS. Finally, we believe further studies with prospective enrollment would be beneficial for more accurate conclusions.

Major Bleeding in the Emergency Department: A Practical Guide for Optimal Management

Major bleeding is a life-threatening condition with high morbidity and mortality. Trauma, gastrointestinal bleeding, haemoptysis, intracranial haemorrhage or other causes of bleeding represent major concerns in the Emergency Department (ED), especially when complicated by haemodynamic instability. Severity and source of bleeding, comorbidities, and prior use of anticoagulants are pivotal factors affecting both the clinical status and the patients' differential response to haemorrhage. Thus, risk stratification is fundamental in the initial assessment of patients with bleeding. Aggressive resuscitation is the principal step for achieving haemodynamic stabilization of the patient, which will further allow appropriate interventions to be made for the definite control of bleeding. Overall management of major bleeding in the ED should follow a holistic individualized approach which includes haemodynamic stabilization, repletion of volume and blood loss, and reversal of coagulopathy and identification of the source of bleeding. The aim of the present practical guide is to provide an update on recent epidemiological data about the most common etiologies of bleeding and summarize the latest evidence regarding the bundles of care for the management of patients with major bleeding of traumatic or non-traumatic etiology in the ED.

Construction and validation of a predictive model for the risk of rebleeding in patients with esophageal and gastric varices hemorrhage

BACKGROUND AND PURPOSE

Esophageal and gastric varices hemorrhage (EGVH) is a life-threatening condition with the 6-week mortality rate of 15-25%. Up to 60% of patients with EGVH may experience rebleeding with a mortality rate of 33%. The existing scoring systems, such as RS scoring system (Rockall score, RS) and GBS scoring system (Glasgow-Blatchford score, GBS), have limitations in predicting the risk of rebleeding. Our study was to construct and validate a novel predictive model for the risk of rebleeding in patients with EGVH and to compare the predictive power of the predictive model with GBS and pRS.

METHODS

Data of patients with EGVH was collected in the First Affiliated Hospital of Dalian Medical University from January 2016 to June 2020. Binary logistic and stepwise regression was performed to construct a predictive model. We compared the predictive power of the new predictive model to the GBS and pRS scoring systems.

RESULTS

Clinical data from a total of 265 patients with EGVH was collected. Six factors including systolic blood pressure, transfusion requirement, CA199, platelet count, upper esophageal varices and severity of esophageal varices were included in our new predictive model. The AUCs of the specificity of the predictive model, GBS and pRS are 0.82, 0.60 and 0.56.

CONCLUSION

This study successfully constructed a predictive model for the risk of rebleeding in patients with EGVH. This predictive model demonstrated higher predictive ability than pRS and GBS scoring systems for assessing rebleeding risk in EGVH patients.

Ionically assembled hemostatic powders with rapid self-gelation, strong acid resistance, and on-demand removability for upper gastrointestinal bleeding

Upper gastrointestinal bleeding (UGIB) is bleeding in the upper part of the gastrointestinal tract with an acidic and dynamic environment that limits the application of conventional hemostatic materials. This study focuses on the development of N-[(2-hydroxy-3-trimethylammonium) propyl] chitosan chloride/phytic acid (HTCC/PA, HP) powders with fast hemostatic capability and strong acid resistance, for potential applications in managing UGIB. Upon contact with liquids within 5 seconds, HP powders rapidly transform into hydrogels, forming ionic networks through electrostatic interactions. The ionic crosslinking process facilitates the HP powders with high blood absorption (3.4 times of self-weight), sufficient tissue adhesion (5.2 and 6.1 kPa on porcine skin and stomach, respectively), and hemostasis (within 15 seconds for in vitro clotting). Interestingly, the PA imparts the HP powders with strong acid resistance (69.8% mass remaining after 10 days of incubation at pH 1) and on-demand removable sealing while HTCC contributes to fast hemostasis and good wet adhesion. Moreover, the HP powders show good biocompatibility and promote wound healing. Therefore, these characteristics highlight the promising clinical potential of HP powders for effectively managing UGIB.

A novel predictive model for Intensive Care Unit admission in Emergency Department patients with upper gastrointestinal bleeding

Acute upper gastrointestinal bleeding (UGIB) is a critical emergency. Conventional scoring models for patients with UGIB have limitations; thus, more suitable tools for the Emergency Department are necessary. We aimed to develop a new model that can identify significant predictors of Intensive Care Unit (ICU) admission in Emergency Department patients with UGIB and to compare its predictive accuracy with that of existing models. We retrospectively analyzed data from patients with UGIB treated between January 2020 and July 2022 at the Emergency Department of a single tertiary medical center. Using multivariable logistic regression and the area under the receiver operating characteristic curve (AUROC), we developed a new model to predict the probability of ICU admission. Among 433 patients, multiple logistic regression analysis identified sex, systolic blood pressure, diastolic blood pressure, hemoglobin level, platelet count, alanine transaminase level, and prothrombin time as significant predictors of ICU admission. Our model demonstrated superior predictive accuracy with an AUROC of 0.8539 (95% confidence interval [CI]: 0.8078-0.8999), outperforming the Glasgow-Blatchford score and AIMS65 score, which had AUROCs of 0.7598 (95% CI: 0.7067-0.8130) and 0.6930 (95% CI: 0.6324-0.7537), respectively. We implemented this model in a user-friendly calculator for clinical use. We identified key predictors of ICU admission that are crucial for hemodynamic stabilization in patients with UGIB. Our model, combined with this probability calculator, will enhance clinical decision-making and patient care for UGIB in emergency settings.

Sequential endoscopic treatment for esophageal and gastric variceal bleeding significantly reduces patient mortality and rebleeding rates

Background

Esophageal-gastric variceal bleeding (EGVB) is a serious complication in patients with liver cirrhosis, characterized by high mortality and rebleeding rates. The effect of sequential endoscopic therapy on patient mortality and rebleeding rates remains unclear.

Objectives

This study aimed to evaluate the effects of sequential endoscopic therapy on mortality and rebleeding rates in patients with EGVB.

Design

In this single-center retrospective study, 373 hospitalized cases of EGVB caused by liver cirrhosis, collected between November 2019 and November 2023, were divided into four groups according to different treatment methods: a sequential endoscopy group, emergency endoscopy group, emergency endoscopy plus transjugular intrahepatic portosystemic shunt (TIPS) group and control group.

Methods

Mortality and rebleeding rates were compared among the four groups using statistical analyses.

Results

The mortality and rebleeding rates of the sequential endoscopy group (3.7% and 19%, respectively) were significantly lower than those of the emergency endoscopy (22% and 36%, respectively), emergency endoscopy plus TIPS (33% and 28%, respectively), and control groups (33% and 51%, respectively) (p = 0.013 and p = 0.013, respectively).

Conclusion

Sequential endoscopic therapy may significantly reduce the mortality and rebleeding rates of patients with EGVB compared to other conventional treatment strategies. The findings of the study could help develop approaches benefiting EGVB treatment.

Gingival Bleeding in a Heavy Drinker

This case report presents a 34-year-old Japanese man with hematemesis who was ultimately diagnosed with gingival bleeding due to periodontitis via esophagogastroduodenoscopy. Although endoscopic examination revealed no gastrointestinal lesions, persistent bleeding from the gums was observed, highlighting the need to consider non-gastrointestinal sources of bleeding in such scenarios. Heavy alcohol consumption likely contributed to poor oral health and increased the risk of oral bleeding. This case emphasizes the importance of thorough endoscopic evaluation of the oral and pharyngolaryngeal regions, particularly when common gastrointestinal sources of bleeding are excluded. A comprehensive diagnostic approach is essential to avoid overlooking less common causes of bleeding.

Systematic review and meta-analysis of endoscopic versus medical management of peptic ulcers with adherent clots

Peptic ulcer disease is an important cause of upper gastrointestinal bleeding. Current guidelines recommend endoscopic treatment for ulcers with active bleeding or non-bleeding visible vessels, but the optimal management of ulcers with adherent clots is unclear. We performed a systematic review of the efficacy of endoscopic versus medical management of peptic ulcers with adherent clots. A systematic literature search was performed through September 2022 (MEDLINE, Embase, and CENTRAL). Randomized controlled trials (RCTs) comparing the effect of endoscopic versus medical management alone for peptic ulcers with adherent clots on the outcome of recurrent bleeding were incuded. A random-effects meta-analysis was performed to estimate the overall treatment effect. We included seven RCTs reporting on the endoscopic versus medical management of peptic ulcers with adherent clots. The pooled cohort comprised 268 patients with a mean age of 62.8 years and a mean follow up of 20 days. There was a significant reduction in the risk of recurrent bleeding with endoscopic hemostatic treatment for peptic ulcers with adherent clots, compared with medical management alone (risk ratio [RR] = 0.40, 95% confidence interval [CI] 0.16-0.95, 268 participants). However, there was no difference in mortality (RR = 0.90, 95% CI 0.23-3.59, 52 participants) or need for ulcer surgery (RR = 0.48, 95% CI 0.10-2.28, 52 participants) between endoscopic and medical management groups. In summary, there was evidence for a reduction in recurrent bleeding from peptic ulcers with adherent clots treated with endoscopic hemostatic techniques compared with medical management alone but no difference in rates of mortality or need for surgery.

Clinical and Biochemical Differences in Patients Having Non-Variceal Upper Gastrointestinal Bleeding on NSAIDs, Oral Anticoagulants, and Antiplatelet Therapy

Introduction: Upper gastrointestinal bleeding (UGIB) is among the most common causes of morbidity and mortality worldwide, accounting for major resource allocation and increasing incidence. This study aimed to evaluate the severity of non-variceal bleeding in patients at risk of bleeding through the use of NSAIDs, oral anticoagulants, and antiplatelet therapy. Material and Method: The study included 296 patients admitted in the Gastroenterology Department of the Municipal County Emergency University Hospital, Timisoara, between 01.01.2018 and 01.04.2020, and diagnosed via gastroscopy with non-variceal gastrointestinal bleeding. The patients were divided among four groups based on their use of different drugs known to induce UGIB, i.e., aspirin and clopidogrel, NOACs, NSAIDs, and anti-vitamin K drugs, respectively. Statistical analyses were performed based on ANOVA one-way tests for continuous variables and Chi-square tests for categorical variables with pairwise comparisons based on Bonferroni adjusted significance tests. Results: The results showed several parameters having statistical significance among the different groups of patients. Patients on NOACs had statistically significant lower hemoglobin levels, lower hematocrit values, lower erythrocytes, lower RDW and higher fibrinogen levels compared to patients on VKA. Discussion: Surprisingly, the results from our study suggest that the use of NOACs was associated with a higher risk of bleeding when compared to VKA, which differs from the existing literature. Conclusions: One of the important factors causing upper non-variceal bleeding can be iatrogenic, either due to antiplatelet drugs or anticoagulants, to which NSAID treatment is additionally associated for various reasons. In our study, the use of NOACs seemed to have a more severe bleeding spectrum with higher morbidity compared to VKA.

Comparison of Vonoprazan Versus Intravenous Proton Pump Inhibitor for Prevention of High-Risk Peptic Ulcers Rebleeding After Successful Endoscopic Hemostasis: A Multicenter Randomized Noninferiority Trial

BACKGROUND & AIMS

High-dose proton pump inhibitor (PPI) therapy has been recommended to prevent rebleeding of high-risk peptic ulcer (PU) after hemostasis. Vonoprazan has been proven to be noninferior to PPIs in various acid-related diseases. This study aimed to compare the efficacy of vonoprazan vs PPI for preventing high-risk PU rebleeding after hemostasis.

METHODS

A multicenter, randomized, noninferiority study was conducted in 6 centers. Pre-endoscopic and endoscopic therapy were performed according to standard protocol. After successful hemostasis, patients with high-risk PU bleeding (Forrest class Ia/Ib, IIa/IIb) were randomized into 1:1 to receive vonoprazan (20 mg twice a day for 3 days, then 20 mg once a day for 28 days) or high-dose PPI (pantoprazole intravenous infusion 8 mg/h for 3 days, then omeprazole 20 mg twice a day for 28 days). The primary outcome was a 30-day rebleeding rate. Secondary outcomes included 3- and 7-day rebleeding rate, all-cause and bleeding-related mortality, rate of rescue therapy, blood transfusion, length of hospital stay, and safety.

RESULTS

Of 194 patients, baseline characteristics, severity of bleeding, and stage of ulcers were comparable between the 2 groups. The 30-day rebleeding rates in vonoprazan and PPI groups were 7.1% (7 of 98) and 10.4% (10 of 96), respectively; noninferiority (within 10% margin) of vonoprazan to PPI was confirmed (%risk difference, -3.3; 95% confidence interval, -11.2 to 4.7; P < .001). The 3-day and 7-day rebleeding rates in the vonoprazan group remained noninferior to PPI (P < .001 by Farrington and Manning test). All secondary outcomes were also comparable between the 2 groups.

CONCLUSION

In patients with high-risk PU bleeding, the efficacy of vonoprazan in preventing 30-day rebleeding was noninferior to intravenous PPI. (ClinicalTrials.gov, Number: NCT05005910).

Antibiotic prophylaxis vs. on‑demand antibiotic treatment in endoscopic therapy for variceal hemorrhage: A meta‑analysis of randomized controlled trials

The aim of the present study was to conduct a meta-analysis for elucidating the effects of antibiotic prophylaxis on infection, rebleeding and mortality in patients who underwent endoscopic therapy for variceal hemorrhage. Articles on antibiotic prophylaxis and on-demand antibiotic administration following endoscopic therapy for acute variceal bleeding were searched on PubMed, Embase and Cochrane Library between January 1959 and February 2024, to elucidate whether the use of prophylactic antibiotics was necessary. The quality of randomized controlled trials (RCTs) was assessed using the Cochrane risk-of-bias assessment tool and RevMan software version 5.4.1 was used for meta-analysis of the data. The current meta-analysis included four RCTs and 322 patients with acute variceal bleeding who underwent endoscopic therapy. All included studies were of high quality according to the Cochrane risk-of-bias assessment tool. According to the results of the meta-analysis, the incidence of infection in the prophylactic antibiotic group was significantly lower than that in the on-demand group [odds ratio (OR), 0.31; 95% confidence interval (CI), 0.13-0.74; P=0.009]. The prophylactic antibiotic group also exhibited a lower incidence of rebleeding compared with that of the on-demand group (OR, 0.37; 95% CI, 0.19-0.72; P=0.003). No significant differences were noted in the incidence of mortality between the two groups (OR, 0.92; 95% CI, 0.45-1.92; P=0.83). In conclusion, the data indicated that antibiotic prophylaxis is recommended to be used in patients who have undergone endoscopic therapy for variceal hemorrhage.

Upper gastrointestinal bleeding as a warning sign of gastrointestinal cancer

Background

Upper gastrointestinal bleeding (UGIB) is a prevalent etiology for hospital admissions on a global scale. However, the significance of UGIB as a warning sign of gastrointestinal (GI) cancer is frequently disregarded due to its uncommon and atypical symptoms.

Methods

In the Kailuan study, participants diagnosed with UGIB were assigned as the case group and were randomly matched in a 1:4 ratio with a control group of comparable age and sex from 2006 to 2018 in Tangshan. The statistical analysis included a total of 1250 UGIB patients and 5000 individuals without UGIB. The impact of UGIB on cancer incidence was evaluated using a Cox proportional hazards model, enabling the investigation of both site-specific and time-dependent effects of UGIB on cancer incidence.

Results

The mean age of the patients was 60.91 ± 13.08 years. Over an average follow-up period of 8.92 years, there were 102 cases of cancer in the UGIB group and 210 cases in the non-UGIB group. The results of the Cox model analysis indicated that the strength of association between UGIB and cancer depends on specific cancer site. Excluding patients with follow-up periods of less than 1, 3, and 5 years weakened the associations between UGIB and GI cancer in sensitivity analysis.

Conclusion

UGIB may serve as a sign of occult cancer, necessitating thorough evaluation of middle-aged and elderly patients presenting with this warning symptom to detect the possibility of missing a cancer diagnosis.

Meta-analysis: Over-the-scope clips in patients at high risk of re-bleeding following upper gastrointestinal tract bleeding

BACKGROUND

Acute non-variceal upper gastrointestinal bleeding (UGIB) is challenging in patients at high risk of re-bleeding in whom standard endoscopic treatment (ST) has limited effectiveness. Over-the-scope clips (OTSC) have shown promise in these patients although their precise role remains uncertain.

AIMS

To confirm the role of OTSC in patients with UGIB at high risk of re-bleeding.

METHODS

We systematically searched CENTRAL, MEDLINE and Embase from January 1st, 1970 to April 24, 2024 for randomised controlled trials (RCTs) comparing OTSC and ST in acute non-variceal UGIB with high re-bleeding risk. The GRADE framework assessed evidence certainty, while trial sequential analysis (TSA) controlled random errors and evaluated conclusion validity.

RESULTS

We analysed four RCTs (319 patients); pooled risk ratio (RR) for clinical success at initial endoscopy favoured OTSC (RR = 1.30, 95% CI = 1.08-1.56, p = 0.006, I2 = 58%, moderate certainty of evidence). TSA showed the desired sample size was 410 and the cumulative Z curve crossing the trial sequential monitoring boundary. The pooled RR for re-bleeding within 30 days favoured OTSC (RR = 0.53, 95% CI = 0.30-0.94, p = 0.03, I2 = 0%, moderate certainty of evidence). There was no significant difference in 30-day mortality, or length of hospital or ICU stay.

CONCLUSIONS

Moderate certainty evidence supports OTSC as a superior initial treatment for acute non-variceal UGIB with high re-bleeding risk. Further large-scale studies are needed to confirm OTSCs' role by exploring other prognostic outcomes and assessing cost-effectiveness and potential complications.

Endoscopy for acute upper gastrointestinal bleeding: a protocol for systematic review and network meta-analysis of randomized controlled trials

Background

Previous studies have reached mixed conclusions regarding the timing of endoscopic approaches for managing individuals with acute upper gastrointestinal bleeding (AUGIB). Therefore, the authors performed a protocol for systematic review and meta-analysis to assess the efficacy of various timing endoscopic approaches in managing individuals with AUGIB.

Methods

The authors will search multiple databases, including PubMed, Embase, Web of Science, China National Knowledge Infrastructure, VIP Database, Wanfang Database, WHO International Clinical Trials Registry Platform, and Chinese Clinical Trial Register. The search will cover the entire duration, starting from the establishment of these databases until July 2023. The selection criteria will focus on randomized controlled trials that assess the efficacy of endoscopy with varying timing in managing patients with AUGIB. The primary outcomes will include primary hemostasis and inpatient death. The secondary outcomes will include recurrent bleeding, need for surgical intervention, admission to the ICU, blood transfusion needs, and duration of hospitalization. Two reviewers will select the studies, extract data, and assess the risk of bias. A Bayesian approach will be used to conduct a network meta-analysis.

Results

The results of this systematic review and meta-analysis will be published in peer-reviewed journals.

Conclusion

This network meta-analysis provides comprehensive evidence of different timing endoscopic approaches for managing individuals with AUGIB.

Ulcer Bleeding in the United States: Epidemiology, Treatment Success, and Resource Utilization

BACKGROUND AND GOALS

Peptic ulcer disease is the most frequent cause of upper gastrointestinal bleeding. We sought to establish the epidemiology and hemostasis success rate of the different treatment modalities in this setting.

METHODS

Retrospective cohort study using the National Inpatient Sample. Non-elective adult admissions with a principal diagnosis of ulcer bleeding were included. The primary outcome was endoscopic, radiologic and surgical hemostasis success rate. Secondary outcomes were patients' demographics, in-hospital mortality and resource utilization. On subgroup analysis, gastric and duodenal ulcers were studied separately. Confounders were adjusted for using multivariate regression analysis.

RESULTS

A total of 136,425 admissions (55% gastric and 45% duodenal ulcers) were included. The mean patient age was 67 years. The majority of patients were males, Caucasians, of lower income and high comorbidity burden. The endoscopic, radiological and surgical therapy and hemostasis success rates were 33.6, 1.4, 0.1, and 95.1%, 89.1 and 66.7%, respectively. The in-hospital mortality rate was 1.9% overall, but 2.4% after successful and 11.1% after failed endoscopic hemostasis, respectively. Duodenal ulcers were associated with lower adjusted odds of successful endoscopic hemostasis, but higher odds of early and multiple endoscopies, endoscopic therapy, overall and successful radiological therapy, in-hospital mortality, longer length of stay and higher total hospitalization charges and costs.

CONCLUSIONS

The ulcer bleeding endoscopic hemostasis success rate is 95.1%. Rescue therapy is associated with lower hemostasis success and more than a ten-fold increase in mortality rate. Duodenal ulcers are associated with worse treatment outcomes and higher resource utilization compared with gastric ulcers.

Perforated Peptic Ulcer: A Case Report of a Dreaded Complication of an Insidious Disease

Perforated peptic ulcers, though relatively rare, represent critical surgical emergencies with potentially life-threatening consequences. Their significance lies not only in their acute presentation but also in the diagnostic challenges they pose, particularly in patients with complex medical histories. Here we present a case of a 71-year-old female with a complex medical history, including insulin-dependent type 2 diabetes mellitus, hypertension, hyperlipidemia, hypothyroidism, dementia, diverticulitis, and chronic back pain, who initially were unresponsive and cyanotic. Despite challenges in diagnosis due to her medical complexity and opioid use, she was ultimately diagnosed with a perforated duodenal ulcer. Tragically, despite immediate surgical intervention, she succumbed to her illness, highlighting the complexities involved in managing perforated peptic ulcers, especially in patients with multiple chronic medical conditions. Peptic ulcer disease (PUD) can often remain asymptomatic, leading to delayed diagnosis and potentially life-threatening complications like perforation. Mortality rates associated with perforated peptic ulcers vary widely, ranging from 1.3% to 20%, with risk factors including nonsteroidal anti-inflammatory drug (NSAID) use, Helicobacter pylori infection, smoking, and corticosteroid use. Diagnosis necessitates a high index of suspicion, thorough clinical examination, and imaging modalities such as computed tomography (CT) scans with oral contrast. Treatment strategies range from nonoperative management with intravenous (IV) histamine H2-receptor blockers or proton pump inhibitors (PPIs) to surgical intervention, depending on the patient's hemodynamic stability. However, the case presented underscores the challenges in timely diagnosis and intervention, particularly in patients with complex medical histories, where symptoms may be masked or attributed to other comorbidities. Recent studies indicate a demographic shift toward older age and a higher prevalence among females, emphasizing the importance of increased awareness and vigilance among healthcare providers. Early recognition of symptoms, prompt investigation, and interdisciplinary collaboration are crucial in optimizing outcomes for patients presenting with perforated peptic ulcers, especially in the context of their underlying medical conditions.

Coffee ground emesis and early endoscopy: Is timing actually relevant?

OBJECTIVE

Coffee ground vomiting is a classical symptom of upper gastrointestinal bleeding. However, the clinical usefulness is limited, due to the low positive predictive value. Our goal is to determine if whether an urgent endoscopy does modify our therapeutic management with a real impact on survival.

PATIENTS AND METHODS

It is a retrospective, observational and descriptive study. We selected all patients that underwent a gastroscopy in our center for coffee ground vomiting over the last 4 years (2017-2021). Two groups were established: urgent endoscopy (first 24h) and scheduled (over 24h). Then we studied differences between both groups regarding survival, ICU admission, hospitalization days and rebleeding.

RESULTS

Three hundred and fourteen patients were identified, from which 276 were included, with 176 belonging to the urgency group and 109 to the scheduled group. There were no differences in the ICU admission, hospitalization days, survival or rebleeding after 30 days. There were no differences either in the number of potentially bleeding lesions or the need of endoscopic therapeutic.

CONCLUSIONS

Coffee ground vomiting, without any other data supporting upper gastrointestinal bleeding, does not represent a reliable indicator. Performing urgent endoscopy is not beneficial in terms of morbimortality. Therefore, a more conservative strategy would allow to differ endoscopy, decreasing risks and reducing costs, without affecting the prognosis.

The Use of Pre-Endoscopic Metoclopramide Does Not Prevent the Need for Repeat Endoscopy: A U.S. Based Retrospective Cohort Study

BACKGROUND

Peptic ulcer disease (PUD) can cause upper gastrointestinal bleeding (UGIB), often needing esophagogastroduodenoscopy (EGD). Second-look endoscopies verify resolution, but cost concerns prompt research on metoclopramide's efficacy compared to erythromycin.

METHODS

We analyzed the Diamond Network of TriNetX Research database, dividing UGIB patients with PUD undergoing EGD into three groups: metoclopramide, erythromycin, and no medication. Using 1:1 propensity score matching, we compared repeat EGD, post-EGD transfusion, and mortality within one month in two study arms.

RESULTS

Out of 97,040 patients, 11.5% received metoclopramide, 3.9% received erythromycin, and 84.6% received no medication. Comparing metoclopramide to no medication showed no significant difference in repeat EGD (10.1% vs. 9.7%, p = 0.34), transfusion (0.78% vs. 0.86%, p = 0.5), or mortality (1.08% vs. 1.08%, p = 0.95). However, metoclopramide had a higher repeat EGD rate compared to erythromycin (9.4% vs. 7.5%, p = 0.003), with no significant difference in transfusion or mortality.

CONCLUSIONS

The need to repeat EGD was not decreased with pre-EGD use of metoclopramide. If a prokinetic agent is to be used prior to EGD, erythromycin shows superior reduction in the need of repeat EGD as compared to metoclopramide.

A systematic review and meta-analysis assessing the use of tranexamic acid (TXA) in acute gastrointestinal bleeding

INTRODUCTION

Gastrointestinal bleeding results in significant morbidity, cost and mortality. TXA, an antifibrinolytic agent, has been proposed to reduce mortality; however, many studies report conflicting results.

METHODS

The aim of the study was to perform the first systematic review and meta-analysis of RCTs to evaluate the efficacy TXA for both upper and lower gastrointestinal bleeding. This was performed per PRISMA guidelines. PubMed, EMBASE, Cochrane and Scopus databases were searched for RCTs. Dichotomous variables were pooled as risk ratios (RR) with 95% confidence intervals (CI) using the MH method with random effects modelling.

RESULTS

Fourteen RCTs were identified with 14,338 patients and mean age of 58.4 years. 34.9% (n = 5008) were female and 65.1% (n = 9330) male. There was no significant difference in mortality between TXA and placebo (RR 0.86 95% CI (0.74 to 1.00), P: 0.05). The secondary outcomes, similarly, did not yield significant results. These included rebleeding, need for surgical intervention (RR: 0.75 95% CI (0.53, 1.07)), endoscopic intervention (RR: 0.92 95% CI (0.70, 1.22)), transfusion requirement (RR: 1.01 95% CI (0.94, 10.7)) and length of stay (RR: 0.03 95% CI (- 0.03, 0.08)). There was no increased risk of VTE, RR: 1.29 95% CI (0.53, 3.16). One trial (n = 12,009) reported an increased risk of seizure in the TXA group, RR: 1.73 95% CI (1.03-2.93).

CONCLUSION

TXA does not reduce mortality in patients with acute upper or lower gastrointestinal bleeding and may confer an increased risk of seizures. The authors do not recommend the use of TXA in acute gastrointestinal bleeding.

Dose of selective serotonin reuptake inhibitors and risk of upper gastrointestinal bleeding in older adults

BACKGROUND

Selective serotonin reuptake inhibitors (SSRIs) have been associated with an increased risk of upper gastrointestinal bleeding (UGIB) in older patients but little is known about the risk associated with individual SSRI drugs and doses.

AIMS

To quantify the risk of UGIB in relation to individual SSRI use in older adults.

METHODS

We conducted a nested case-control study within a cohort of 9565 patients aged ⩾65 years prescribed SSRIs from 2000 to 2013 using claims data of universal health insurance in Taiwan. Incident cases of UGIB during the follow-up period were identified and matched with three control subjects. Conditional logistic regression was used to estimate the odds ratio (OR) of UGIB associated with individual SSRI use and cumulative dose.

RESULTS

UGIB risk increased with the increasing cumulative doses of SSRIs (adjusted OR: 1.28, 95% confidence interval (CI): 1.02-1.62 for the highest vs. the lowest tertile). Compared with users of other SSRIs, fluoxetine users were at an increased risk of UGIB (adjusted OR: 1.25, 95% CI: 1.03-1.50) with a dose-response manner, whereas paroxetine users had 29% decreased odds (95% CI: 0.56-0.91). The increased risk was only observed among current fluoxetine users.

CONCLUSIONS

Fluoxetine therapy was associated with an increased risk of UGIB in a dose-response manner among older adults.

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.

A novel strategy of combining abdominal surgery and endoscopy for the quick hemostasis of acute duodenal ulcer bleeding: a case report

BACKGROUND

Uncontrolled ulcer bleeding of duodenal ulcer (DU) after endoscopic therapy often needs surgery. At present, cutting the bottom of the ulcer with ligation and performing its excision-lesion are the common ways to achieve immediate efficacy in stopping bleeding. For the problem of its great trauma, we seek an easy and useful technical method to reach the same therapeutic effect to stop acute bleeding.

METHODS

We determined the distribution of the lesion and its innervated blood vessels under the guidance of the endoscopy and then performed suture and hemostasis on the external surface of the stomach and duodenum.

RESULTS

An immediate efficacy in stopping bleeding was shown and the hemoglobin (Hb) level returned to normal after operation with no recurrence of bleeding.

CONCLUSION

We created a successful and novel strategy for laparotomy-endoscopic assisted suture for DU emergency hemostasis without duodenectomy.

Varicose vein embolization and portal vein stenting in a patient with sinistral portal hypertension-induced gastrointestinal hemorrhage: a case report

Introduction and importance

Massive gastrointestinal hemorrhage is a severe hemorrhage that occurs in the gastrointestinal tract and is a life-threatening condition. Sinistral portal hypertension is a common etiology for massive gastrointestinal hemorrhage, whose occurrence might be derived from pathological changes induced by obstruction and/or increased blood flow to the portal vein system. However, there is a rare study reporting pancreatic disease-induced sinistral portal hypertension.

Case presentation

An 80-year-old female pancreatic cancer patient was admitted to our hospital on 22 January 2022 due to a massive gastrointestinal hemorrhage with shock after receiving radio-chemotherapy. Abdominal enhanced computerized tomography showed that the patient presented with pancreatic cancer-causing sinistral portal hypertension with massive collateral circulation, intrahepatic bile duct dilation, and the formation of massive ascites. Subsequent portography interventional procedure revealed the esophageal and gastric varix. Then, the varicose vein was embolized, and the stent was implanted at the lumen of the superior mesenteric vein accessing the portal vein. The patient recovered from pancreatic cancer-causing sinistral portal hypertension, and a normal direction of blood flow was observed in the superior mesenteric vein with a decreasing amount of ascites. In addition, a transfusion was also carried out, and the massive gastrointestinal hemorrhage was alleviated.

Clinical discussion and conclusion

This study emphasizes the successful treatment of massive gastrointestinal hemorrhage induced by pancreatic cancer-causing sinistral portal hypertension by varicose vein embolization and portal vein stenting, which could be considered an alternative opinion for these patients.

Role of endoscopic ultrasound in non-variceal upper gastrointestinal bleeding management

Non-variceal upper gastrointestinal bleeding (NVUGIB) is one of the challenging situations in clinical practice. Despite that gastric ulcer and duodenal ulcer are still the main causes of acute NVUGIB, there are other causes of bleeding which might not always be detected through the standard endoscopic evaluation. Standard endoscopic management of UGIB consists of injection, thermal coagulation, hemoclips, and combination therapy. However, these methods are not always successful for rebleeding prevention. Endoscopic ultrasound (EUS) has been used recently for portal hypertension management, especially in managing acute variceal bleeding. EUS has been considered a better tool to visualize the bleeding vessel in gastroesophageal variceal bleeding. There have been studies looking at the role of EUS for managing NVUGIB; however, most of them are case reports. Therefore, it is important to review back to see the evolution and innovation of endoscopic treatment for NVUGIB and the role of EUS for possibility to replace the standard endoscopic haemostasis management in daily practice.

Gastrointestinal Bleeding in Children: The Role of Endoscopy and the Sheffield Scoring System in a Resource-Limited Setting

Objective

To document the clinical presentation, endoscopic diagnosis, and Sheffield scores of children with gastrointestinal (GI) bleeding who were referred for endoscopy at the Lagos University Teaching Hospital. The participants who needed endoscopy based on clinical criteria and according to the Sheffield scores were also documented.

Methods

This study analyzed the records of 111 children with GI bleeding retrospectively from January 2013 to January 2021, while 9 children were recruited prospectively from February 2021 to March 2022. Receiver operating curves and area under the curve were generated to test the ability of the Sheffield scores to predict rebleeds, mortality, and the need for endoscopic intervention for upper GI bleeds.

Results

One hundred and twenty participants were recruited. Ninety-one (75.8%) presented with upper GI bleeding (UGIB), while 29 (24.2%) had lower GI bleeding (LGIB). Only 70 (58.3%) (53 UGIB and 17 LGIB) had endoscopy performed. For UGIB, 5 (9.4%) had no source of the bleeding identified at endoscopy, 12 (22.6%) had variceal bleeding, and 36 (67.9%) had nonvariceal bleeding. Colonoscopy revealed juvenile polyps in 5 (29.4%), indeterminate colitis in 5 (29.4%), ulcerative colitis in 4 (23.5%), Crohn's disease in 1 (5.9%), and hemorrhoids in 2 (11.8%) participants, respectively. The Sheffield score was ≥8 in 42 (46.1%) of the participants who presented only with UGIB (hematemesis and melena). The scores were significantly related to the type of bleeds, rebleeds, and deaths (P = 0.00).

Conclusion

The clinical and endoscopic findings in this study are similar to those reported previously. The Sheffield scoring was useful in assessing Nigerian children. However, due to limited access and other restraints, endoscopy was not performed on all the study participants even when the scoring system was suggestive. The availability, and therefore, utility of GI endoscopy in this setting are still suboptimal. The need for the provision of adequate equipment and resources and the training of personnel is thus recommended.

Admission Hypocalcemia and the Need for Endoscopic and Clinical Interventions among Patients with Upper Gastrointestinal Bleeding

INTRODUCTION

Calcium is an essential co-factor in the coagulation cascade, and hypocalcemia is associated with adverse outcomes in bleeding patients, including trauma patients, women with postpartum hemorrhage, and patients with intracranial hemorrhage. In this retrospective, single-center, cohort study, we aimed to determine whether admission-ionized calcium (Ca++) is associated with higher rates of therapeutic interventions among patients presenting with acute nonvariceal upper gastrointestinal bleeding (NV-UGIB).

METHODS

Adult patients admitted due to NV-UGIB between January 2009 and April 2020 were identified. The primary outcome was defined as a need for clinical intervention (two or more packed cell transfusions, need for endoscopic, surgical, or angiographic intervention). Univariate and multivariable logistic regression analyses were performed to determine whether Ca++ was an independent predictor of the need for therapeutic interventions. Propensity score matching was performed to adjust the imbalances of covariates between the groups.

RESULTS

A total of 434 patients were included, of whom 148 (34.1%) had hypocalcemia (Ca++ <1.15 mmol/L). Patients with hypocalcemia were more likely to require therapeutic interventions than those without hypocalcemia (48.0% vs. 18.5%, p < 0.001). Specifically, patients with hypocalcemia were more likely to require endoscopic intervention for control of bleeding (25.0% vs. 15.7%, p = 0.03) and multiple packed cell transfusions (6.8% vs. 0.3%, p < 0.001). Additionally, they had significantly longer hospital stay (5.0 days [IQR 3.0-8.0] vs. 4.0 days [IQR 3.0-6.0], p = 0.01). After adjusting for multiple covariates, Ca++ was an independent predictor of the need for therapeutic intervention (aOR 1.62, 95% confidence interval [CI] 1.22-2.14, p < 0.001). The addition of Ca++ to the Modified Glasgow Blatchford score improved its accuracy in the prediction of therapeutic intervention from AUC of 0.68 (95% CI 0.63-0.72) to 0.72 (95% CI 0.67-0.76), p = 0.02. After incorporation of the propensity score, the results did not change significantly.

CONCLUSION

These findings suggest that hypocalcemia is common and is associated with an adverse clinical course in patients with NV-UGIB. Measurement of Ca++ on admission may facilitate risk stratification in these patients. Trials are needed to assess whether the correction of hypocalcemia will lead to improved outcomes.

Melatonin protects against ketorolac induced gastric mucosal toxic injuries through molecular mechanism associated with the modulation of Arylakylamine N-Acetyltransferase (AANAT) activity

Ketorolac tromethamine (KT), is a widely used non-steroidal anti-inflammatory drug (NSAID) for treating moderate to severe pain. However, the use of KT has been restricted due to its highly toxic attributes that lead to severe gastric ulceration and bleeding. The protective effects of exogenous melatonin (MT) has been reported in conditions associated with gastro-intestinal disorders. This study aims at exploring the role of gastric endogenous MT level and it's metabolizing enzyme AANAT, at the onset of ketorolac mediated toxicities in the gastric mucosa. Gastric mucosal damage was induced in experimental rats by oral administration of graded doses of KT, where 50 mg/kg b.w. of KT was observed to incur maximum gastric lesions. However, gastric damages were found to be protected in rats, pre-treated with 60 mg/kg b.w. of MT. Post-sacrifice, mean ulcer index, oxidative status, total melatonin levels and enzyme activities associated with MT biosynthesis and catabolism were estimated. The results reveal that KT decreases AANAT activity with a concomitant decline in endogenous MT level which cumulatively aggravates gastric toxicity. Moreover, exogenous MT administration has been found to be protective in ameliorating this ulcerogenic process in rats, challenged with KT. Biochemical and histo-pathological observations revealed the reduction in oxidative stress level and replenishment of depleted gastric MT levels in MT pre-treated animals, which might be the causative factors in conferring protection to the gastric tissues and residing mitochondria. The results revealed a correlation between depleted gastric MT level and ulcer formation, which unveiled a novel ulcerogenic mechanism. This may bring forth future therapeutic relevance for treating patients suffering from KT mediated acute gastric toxicities.

Hepatic venous pressure gradient and rebleeding risk of patients with nonalcoholic steatohepatitis cirrhosis after variceal bleeding

Background and aims

Hepatic venous pressure gradient (HVPG) has a strong predictive value for variceal rebleeding in cirrhotic patients, but the accuracy of HVPG may be compromised in nonalcoholic steatohepatitis (NASH) cirrhosis. This study aimed to evaluate the accuracy of HVPG and portal pressure gradient (PPG) for predicting rebleeding in NASH cirrhosis after acute variceal bleeding.

Patients and methods

Thirty-eight NASH cirrhosis patients and 82 hepatitis B virus (HBV) cirrhosis patients with acute variceal bleeding were included in this study. All patients recived transjugular intrahepatic portalsystemic shunt (TIPS). The prognostic value of HVPG and PPG for variceal rebleeding was evaluated.

Results

Compared with HBV cirrhosis, NASH cirrhosis demonstrated a lower HVPG (15.3 ± 3.8 vs. 18.0 ± 4.8; p = 0.003) and lower PPG (18.0 ± 3.7 vs. 20.0 ± 3.4; p = 0.005). HVPG (AUC = 0.82; p = 0.002) and PPG (AUC = 0.72; p = 0.027) had promising prognostic value among NASH cirrhosis patients. The optimal threshold of HVPG and PPG for predicting rebleeding in NASH cirrhosis was 17 mmHg and 20 mmHg. At multivariate analysis, HVPG ≥17 mmHg was a significant predictor of variceal rebleeding (HR 9.40; 95% CI 1.85-47.70; p = 0.007).

Conclusion

In the patients with cirrhosis and vairceal bleeding, the levels of HVPG and PPG were found to be low in NASH cirrhosis than HBV cirrhosis. However, the prevalence of rebleeding was similar between two groups. HVPG measurement is still an accurate way to assess the risk of variceal rebleeding in NASH cirrhosis.

Peptic ulcer disease complicated with choledocho-duodenal fistula and gastro-intestinal bleeding: a case report and review of the literature

Peptic ulcer disease (PUD) is a very common condition, with an annual incidence ranging from 0.1% to 0.3% and a lifetime prevalence ranging from 5% to 10%. If not treated, it can lead to severe complications such as gastro-intestinal bleeding, perforation, or entero-biliary fistula. Entero-biliary fistulas and especially choledocho-duodenal fistula (CDF) are a rare, but relevant and important diagnosis, which can lead to several complications such as gastric outlet obstruction, bleeding, perforation, or recurrent cholangitis. In this article, we present the case of an 85-year-old woman with PUD complicated with gastro-intestinal bleeding and a CDF. We also performed a review of the literature to search for pre-existing cases with this atypical clinical presentation. The aim was to raise awareness among surgeons and clinicians by offering a summary of different types of entero-biliary and especially CDF, existing diagnostic investigations, and management.

Trends of Upper Gastrointestinal Bleeding Mortality in the United States Before and During the COVID-19 Era: Estimates From the Centers for Disease Control WONDER Database

Background

There have been reports of increased upper gastrointestinal bleeding (UGIB) in patients with coronavirus disease 2019 (COVID-19). Still, only a few studies have examined the mortality rate associated with UGIB in the United States before and during COVID-19. Hereby, we explored the trends of UGIB mortality in the United States before and during COVID-19. The study's objective was to investigate whether the COVID-19 pandemic significantly impacted UGIB mortality rates in the USA.

Methods

The decedents with UGIB were included. Age-standardized mortality rates were estimated with the indirect method using the 2000 US Census as the standard population. We utilized the deidentified data from the Centers for Disease Control and Prevention Wide-Ranging Online Data for Epidemiologic Research (CDC WONDER) database. Linear regression analysis was performed to determine 2021 projected mortality rates based on trends between 2012 and 2019 to quantify the association of the pandemic with UGIB-related deaths.

Results

The mortality rate increased from 3.3 per 100,000 to 4.3 per 100,000 among the population between 2012 and 2021. There was a significant increase in the overall mortality rate between each year and the following year from 2012 to 2019, ranging from 0.1 to 0.2 per 100,000, while the rise in the overall mortality rate between each year and 2021 ranges from 0.4 to 0.9 per 100,000.

Conclusions

Our results showed that the mortality rate increased among the population between 2012and 2021, suggesting a possible influence of COVID-19 infection on the incidence and mortality of UGIB.

Previous antithrombotic therapy does not have an impact on the in-hospital mortality of patients with upper gastrointestinal bleeding

The association between antithrombotics (ATs) and the risk of gastrointestinal bleeding is well known; however, data regarding the influence of ATs on outcomes are scarce. The goals of this study are: (i) to assess the impact of prior AT therapy on in-hospital and 6-month outcomes and (ii) to determine the re-initiation rate of the ATs after a bleeding event. All patients with upper gastrointestinal bleeding (UGB) who underwent urgent gastroscopy in three centres from 1 January 2019 to 31 December 2019 were retrospectively analysed. Propensity score matching (PSM) was used. Among 333 patients [60% males, mean age 69.2 (±17.3) years], 44% were receiving ATs. In multivariate logistic regression, no association between AT treatment and worse in-hospital outcomes was observed. Development of haemorrhagic shock led to worse survival [odds ratio (OR) 4.4, 95% confidence interval (CI) 1.9-10.2, P < 0.001; after PSM: OR 5.3, 95% CI 1.8-15.7, P = 0.003]. During 6-months follow-up, higher age (OR 1.0, 95% CI 1.0-1.1, P = 0.002), higher comorbidity (OR 1.4, 95% CI 1.2-1.7, P < 0.001), a history of cancer (OR 3.6, 95% CI 1.6-8.1, P < 0.001) and a history of liver cirrhosis (OR 2.2, 95% CI 1.0-4.4, P = 0.029) were associated with higher mortality. After a bleeding episode, ATs were adequately re-initiated in 73.8%. Previous AT therapy does not worsen in-hospital outcomes in after UGB. Development of haemorrhagic shock predicted poor prognosis. Higher 6-month mortality was observed in older patients, patients with more comorbidities, with liver cirrhosis and cancer.

External validation of Glasgow-Blatchford, modified Glasgow-Blatchford and CANUKA scores to identify low-risk patients with upper gastrointestinal bleeding in emergency departments: a retrospective cohort study

BACKGROUND

Upper gastrointestinal bleeding (UGIB) is a medical emergency with an approximate mortality of 10%, which results in a high hospitalisation rate. The Glasgow-Blatchford score (GBS) is recommended to identify low-risk patients who can be discharged from the emergency department (ED). A modified GBS (mGBS) and CANUKA score have recently been proposed but have not been well studied. The aim of this study was to assess whether the use of GBS, mGBS or CANUKA score could identify patients at low risk of death or need for intervention.

METHODS

A single-centre retrospective study was performed including patients with suspected UGIB visiting the ED of Saint-Antoine hospital (Paris, France) from January 2016 to December 2018. Demographic and medical data needed to calculate GBS and CANUKA were collected, as well as outcomes data. Need for intervention was defined as the need for blood transfusion, endoscopic haemostasis or rebleeding within 7 days. In-hospital mortality was also collected. Sensitivity, specificity and predictive values were measured for the score thresholds of interest.

RESULTS

A total of 386 patients were included. Median age was 60 years (38-78), 65.3% (n=252) were male and 60% (n=233) were hospitalised. A GBS≤1, mGBS=0 and CANUKA≤2 categorised 24.9%, 18.2% and 18.9% of patients as low risk, respectively. There was a need for intervention in 2.2%, 4.6% and 0% of those patients categorised as low risk by GBS, mGBS and CANUKA, respectively. No deaths occurred in the patients identified as low risk, regardless of the score used. All scores had a high sensitivity and negative predictive value.

CONCLUSIONS

In patients with UGIB, the use of a GBS≤1 or CANUKA score ≤2 appears to be safe for identifying patients at low risk of death or need for intervention.

Use of over-the-scope clip (OTSC) versus standard therapy for the prevention of rebleeding in large peptic ulcers (size ≥1.5 cm): an open-labelled, multicentre international randomised controlled trial

INTRODUCTION

Over-the-scope clip (OTSC) has been used recently for primary haemostasis of peptic ulcers. This study aimed to compare the efficacy of OTSC to standard endoscopic therapy in primary treatment of patients with peptic ulcer bleeding that are of size ≥1.5 cm. The target population accounts for only 2.5% of all upper GI bleeders.

METHODS

This was a multicentre international randomised controlled trial from July 2017 to October 2020. All patients with Forest IIa or above peptic ulcers of ≥1.5 cm were included. Primary outcome was 30-day clinical rebleeding. Secondary endpoints include 3-day all-cause mortality, transfusion requirement, hospital stay, technical and clinical success, and further interventions. 100 patients are needed to yield a power of 80% to detect a difference of -0.15 at the 0.05 significance level (alpha) using a two-sided Z-test (pooled).

RESULTS

100 patients were recruited. Success in achieving primary haemostasis was achieved in 46/50 (92%) and 48/50 (96%) in the OTSC and conventional arm, respectively. Among patients who had success in primary haemostasis, 2/46 (4.35%) patients in the OTSC arm and 9/48 (18.75%) patients in the conventional arm developed 30-day rebleeding (p=0.03). However, in an intention-to-treat analysis, there was no difference in rebleeding within 30 days (5/50 (10%) OTSC vs 9/50 (18%) standard, p=0.23) or all-cause mortality (2/50 (4%) OTSC vs 4/50 (8%) standard, p=0.68; OR=2.09, 95% CI 0.37 to 11.95). There was also no difference in transfusion requirement, hospital stay, intensive care unit admission and further interventions.

CONCLUSION

The routine use of OTSC as primary haemostasis in large bleeding peptic ulcers was not associated with a significant decrease in 30-day rebleeding.

A Rare Case of a Gastric Ulcer Causing Left Gastric Artery Pseudoaneurysm

Upper gastrointestinal hemorrhage is an uncommon but can be a lethal presentation of a pseudoaneurysm because a rupture is associated with a 40%–80% mortality rate. We report a rare case of left gastric artery pseudoaneurysm secondary to peptic ulcer disease presenting as an upper gastrointestinal hemorrhage.

Management of Acute Upper Gastrointestinal Bleeding in Critical Care Transport

Upper gastrointestinal bleeding is a relatively common and life-threatening condition encountered by critical care transport crews. It is of paramount importance that transport crews understand the underlying pathophysiology of variceal and nonvariceal gastrointestinal bleeding as well as the nuanced management of this patient population. This article reviews the current clinical evidence on initial resuscitation, medical management, and advanced invasive therapies (such as balloon tamponade devices) that transport crews should be familiar with to manage these patients. In addition, we present a novel method of continuous balloon pressure monitoring of balloon tamponade devices that is applicable to the transport environment.

External validation and comparison of the Glasgow-Blatchford score, modified Glasgow-Blatchford score, Rockall score and AIMS65 score in patients with upper gastrointestinal bleeding: a cross-sectional observational study in Western Switzerland

Upper gastrointestinal bleeding (UGIB) presents a high incidence in an emergency department (ED) and requires careful evaluation of the patient's risk level to ensure optimal management. The primary aim of this study was to externally validate and compare the performance of the Rockall score, Glasgow-Blatchford score (GBS), modified GBS and AIMS65 score to predict death and the need for an intervention among patients with UGIB. This was a cross-sectional observational study of patients consulting the ED of a Swiss tertiary care hospital with UGIB. Primary outcomes were the inhospital need for an intervention, including transfusion, or an endoscopic procedure or surgery or inhospital death. The secondary outcome was inhospital death. We included 1521 patients with UGIB, median age, 68 (52-81) years; 940 (62%) were men. Melena or hematemesis were the most common complaints in 1020 (73%) patients. Among 422 (28%) patients who needed an intervention or died, 76 (5%) died in the hospital. Accuracy of the scoring systems assessed by receiver operating characteristic curves showed that the Glasgow-Blatchford bleeding and modified GBSs had the highest discriminatory capacity to determine inhospital death or the need of an intervention [AUC, 0.77 (95% CI, 0.75-0.80) and 0.78 (95% CI, 0.76-0.81), respectively]. AIMS65 and the pre-endoscopic Rockall score showed a lower discrimination [AUC, 0.68 (95% CI, 0.66-0.71) and 0.65 (95% CI, 0.62-0.68), respectively]. For a GBS of 0, only one patient (0.8%) needed an endoscopic intervention. The modified Glasgow-Blatchford and Glasgow-Blatchford bleeding scores appear to be the most accurate scores to predict the need for intervention or inhospital death.

The Effectiveness of Student-Led Ward Round Training on Knowledge Acquisition, Critical Thinking Ability, and Self-Confidence of Acute Upper Gastrointestinal Bleeding for Nursing Students

INTRODUCTION

Nursing knowledge, critical thinking ability, and self-perceived confidence are imperative to nursing skills in professional nursing practice. Therefore, nurse educators are required to use teaching strategies that will help promote their knowledge, critical thinking, and self-confidence in complex contents such as the nursing of acute upper gastrointestinal bleeding (AUGIB).

PURPOSE

This study compares the effect of student-led and instructor-led ward-round training methods on knowledge acquisition, critical thinking ability, and self-perceived confidence during AUGIB sessions.

METHODS

Forty nursing students in the first year of the Emergency Nursing Residency Program were randomly divided into a student-led ward round training group (SG) and an instructor-led ward round training group (IG) with a ratio of 1:1. A knowledge quiz, critical thinking ability test, and self-perceived confidence questionnaire were performed before and after the ward round training to assess both groups of students for their knowledge acquisition, critical thinking ability, and self-perceived confidence improvement. Feedback questionnaires were conducted after the training to evaluate students' perspectives and interests concerning the teaching module.

RESULTS

The scores of the post-training quiz were significantly higher than that of the pre-training quiz in both the SG (44.10±2.92 vs 31.10±4.27, p<0.001) and IG (32.35±2.21 vs 30.55±2.24, p=0.01). In the post-training quiz, scores achieved by the students from the SG (44.10±2.92) were significantly higher than those achieved by the students from the IG (32.35±2.21, p< 0.001). The level of self-perceived confidence improved significantly after ward round training in the SG (p< 0.001). However, there was no statistically significant difference in the IG with respect to the change from pre- to post-training (p=0.43).The students' critical thinking ability improved significantly in the SG (14.95±2.58 vs 7.10±1.79, p<0.001), while no significant improvement was found in the IG (7.91±2.28 vs 6.52±2.21, p=0.07) after ward round training.

CONCLUSION

The teaching method of SWRT improves nursing students' knowledge acquisition, critical thinking ability, and self-perceived confidence in AUGIB.

The effect of prophylactic antibiotics in acute upper gastrointestinal bleeding patients in the emergency department

BACKGROUND

Currently, prophylactic antibiotics are recommended only for cirrhotic patients with acute upper gastrointestinal bleeding (AUGIB); however, the benefit for other AUGIB patients remains undetermined. We aimed to compare the clinical outcomes between patients with AUGIB with and without prophylactic antibiotics to identify the population that requires this therapy.

METHODS

Patients with AUGIB admitted between 1st January 2019 and 31st December 2021 in the Emergency Department of Peking Union Medical College Hospital were enrolled. Patients were divided into the antibiotic and non-antibiotic groups. The primary outcome was in-hospital mortality, and the secondary outcome was the onset of new infection. The risk factors for mortality and infection were analyzed, and stratification analysis of prophylactic antibiotics was performed. Continuous data were analyzed using the t-test or nonparametric rank sum test, and categorical data were analyzed using the Chi-square test or Fisher's exact test. Indicators with significant differences between the groups were included for logistic regression analysis. A P-value <0.05 was considered statistically significant.

RESULTS

A total of 392 individuals were included, among them, 281 patients received prophylactic antibiotics, and 111 patients did not receive prophylactic antibiotics. The mortality rates were significantly lower in the antibiotic group than in the non-antibiotics group (6.41% vs. 17.12%, P=0.001). The risk factors for infection were varicose veins (P=0.045) and endotracheal intubation (P=0.005) in the prophylactic antibiotic group, and endoscopic treatment (P=0.010) in the non-prophylactic antibiotic group. Stratified analyses showed that patients with age ≥ 65 years, endotracheal intubation, endoscopic treatment, and AUGIB of variceal etiologies benefited from prophylactic antibiotics.

CONCLUSION

AUGIB patients may benefit from prophylactic antibiotics to decrease mortality, especially those aged ≥ 65 years and those with endotracheal intubation, endoscopic treatment, and variceal etiologies.

Unmasking lower gastrointestinal bleeding under administration of norepinephrine

BACKGROUND

Bleeding in the gastrointestinal tract is common and transarterial embolization enables the clinician to control gastrointestinal bleeding. Contrast extravasation is a prerequisite for successful embolization. Provocative angiography is helpful in the detection of elusive bleeding.

AIM

We performed a retrospective analysis of angiographic treatment in patients with lower gastrointestinal hemorrhage and initially negative angiographies, as well as the role of norepinephrine (NE) in unmasking bleeding.

METHODS

We analyzed 41 patients with lower gastrointestinal bleeding after angiography who had undergone treatment over a period of 10 years. All patients had a positive shock index and needed intensive care.

RESULTS

In three of four patients, angiography disclosed the site of bleeding when NE was used during the procedure for hemodynamic stabilization.

CONCLUSION

We suggest that angiography performed after the administration of NE in unstable patients with gastrointestinal bleeding and an initially negative angiography has the potential to unmask bleeding sites for successful embolization. However, this statement must be confirmed in prospective studies.

ABC score is an effective predictor of outcomes in peptic ulcer bleeding

BACKGROUND

Risk stratification is recommended for patients with gastrointestinal (GI) bleeding. The ABC score is a new scoring tool with high accuracy for upper and lower GI bleeding. We aimed to evaluate the effectiveness of the ABC score in predicting the outcomes of patients with peptic ulcer bleeding.

METHODS

This single-center retrospective study included 809 patients, each with symptoms of upper GI bleeding, and who were diagnosed with ulcerative lesions between October 2011 and March 2021. The association between the ABC score's variables and the patients' outcome was analyzed. The score's performance in predicting the patients' outcome was validated using receiver-operating characteristic curve analysis and compared with that of other scores.

RESULTS

The study analyzed 772 patients with peptic ulcer bleeding. The primary outcome measure was all-cause 30-day mortality. Secondary outcome measures included rebleeding within 30 days and the need for radiologic/surgical intervention. Age (P = .013), serum albumin levels (P < .001), serum creatinine levels (P = .004), mental status (P < .001), and American Society of Anesthesiologists score (P < .001) were associated with the primary outcome. The ABC score predicted the 30-day mortality (area under the receiver-operating characteristic curve [AUROC] 0.927; 95% confidence interval [CI] 0.899-0.956) better than other scores. However, it was less accurate in predicting rebleeding (AUROC 0.630; 95% CI 0.563-0.697) and need for radiologic/surgical intervention (AUROC 0.641; 95% CI 0.550-0.732).

CONCLUSIONS

The ABC score accurately predicts the 30-day mortality in patients with peptic ulcer bleeding. However, it may not be suitable for predicting rebleeding or the need for radiologic/surgical interventions.

Risk factors, prediction model, and prognosis analysis of myocardial injury after acute upper gastrointestinal bleeding

Background

Cardiovascular complications in patients with acute upper gastrointestinal bleeding (AUGIB) have been associated with a high-risk of subsequent adverse consequences. This study aimed to analyze the risk factors for myocardial injury in AUGIB patients, predict the risk of myocardial injury, and explore the clinical prognosis and influencing factors in AUGIB patients with myocardial injury.

Materials and methods

A retrospective case-control study based on AUGIB patients in the First Affiliated Hospital of Xi'an Jiaotong University from 2016 to 2020 was performed. We divided the enrolled patients into a myocardial injury group and a control group according to whether they developed myocardial injury. The variables significant in the univariate analysis were subjected to binary logistic regression for risk factor analysis and were used to establish a nomogram for predicting myocardial injury. In addition, logistic regression analysis was performed to better understand the risk factors for in-hospital mortality after myocardial injury.

Result

Of the 989 AUGIB patients enrolled, 10.2% (101/989) developed myocardial injury. Logistic regression analysis showed that the strong predictors of myocardial injury were a history of hypertension (OR: 4.252, 95% CI: 1.149-15.730, P = 0.030), blood urea nitrogen (BUN) (OR: 1.159, 95% CI: 1.026-1.309, P = 0.018) and left ventricular ejection fraction (LVEF) <68% (OR: 3.667, 95% CI: 1.085-12.398, P = 0.037). The patients with a tumor history (digestive system tumors and non-digestive system tumors) had no significant difference between the myocardial injury group and the control group (P = 0.246). A prognostic nomogram model was established based on these factors with an area under the receiver operator characteristic curve of 0.823 (95% CI: 0.730-0.916). The patients with myocardial injury had a much higher in-hospital mortality rate (10.9% vs. 2.0%, P < 0.001), and an elevated D-dimer level was related to in-hospital mortality among the AUGIB patients with myocardial injury (OR: 1.273, 95% CI: 1.085-1.494, P = 0.003).

Conclusion

A history of hypertension, renal dysfunction, and cardiac function with LVEF <68% were strong predictors of myocardial injury. Coagulopathy was found to be associated with poor prognosis in AUGIB patients with myocardial injury.

Evaluation of transjugular intrahepatic portosystemic shunt and modified sclerotherapy in preventing rebleeding of esophageal and gastric varices

Esophageal and gastric varices are complications of decompensated portal hypertension due to cirrhosis, and gastrointestinal bleeding and can seriously trigger major bleeding and crisis life. Seriously endangers patients' physical and mental health and attracts great attention in the clinic. To compare the efficacy and safety of MES (combined with lauromacrogol and tissue adhesive) and TIPS in the treatment of esophageal and gastric varices. The 62 cases of esophageal and gastric variceal bleeding in our hospital were retrospectively analyzed. They were divided into the MES group and TIPS group according to the treatment method. The rebleeding rate, complications, 2-year birth rate, treatment cost, and hospitalization time within 2 years after operation were compared between the two groups. Among the 62 patients, there were 32 in the MES group and 30 in the TIPS group. The rebleeding rate within 1 year after operation in the MES group was higher than that in the TIPS group, but the difference was not statistically significant. The rebleeding rate within 2 years after operation in the MES group was 40.63%, significantly higher than 13.33% in the TIPS group (P < 0. 05). In the MES group, the incidence of hepatic encephalopathy after the operation was 9.38%, significantly lower than 33.33% in TIPS group (P < 0. 05). The survival rate within 2 years after operation in MES group (81.25%) and TIPS group (83.33), the difference was not statistically significant (P > 0.05). There was no significant difference in hospital stay between the MES group and TIPS group (P > 0.05). The treatment cost of the MES group was lower than that of the TIPS group (P < 0.05). MES is more suitable for development and promotion in grass-roots hospitals, but TIPS treatment should be carried out as soon as possible for patients with poor efficacy of endoscopic treatment.

Transarterial Embolization for Active Gastrointestinal Bleeding: Predictors of Early Mortality and Early Rebleeding

Background: The aim of this study was to determine predictive factors of early mortality and early rebleeding (≤30 days) following transarterial embolization (TAE) for treatment of acute gastrointestinal bleeding. Methods: All consecutive patients admitted for acute gastrointestinal bleeding to the interventional radiology department in a tertiary center between January 2012 and January 2022 were included. Exclusion criteria were patients: (1) aged < 18-year-old, (2) referred to the operation room without TAE, (3) treated for hemobilia, (4) with mesenteric hematoma, (5) lost to follow-up within 30 days after the procedure. We evaluated pre and per-procedure clinical data, biological data, outcomes, and complications. Results: Sixty-eight patients were included: 55 (80.9%) experienced upper gastrointestinal bleeding and 13 (19.1%) lower gastrointestinal bleeding. Median age was 69 (61−74) years. There were 49 (72%) males. Median hemoglobin was 7.25 (6.1−8.3) g/dL. There were 30 (50%) ulcers. Coils were used in 46 (67.6%) procedures. Early mortality was 15 (22.1%) and early rebleeding was 17 (25%). In multivariate analysis, hyperlactatemia (≥2 mmol/L) were predictive of early mortality (≤30 days). A high number of red blood cells units was associated with early rebleeding. Conclusion: This study identified some predictive factors of 30-day mortality and early rebleeding following TAE. This will assist in patient selection and may help improve the management of gastrointestinal bleeding.

Clinical outcomes of acute upper gastrointestinal bleeding according to the risk indicated by Glasgow-Blatchford risk score-computed tomography score in the emergency room

BACKGROUND/AIMS

Acute upper gastrointestinal (UGI) bleeding is a significant emergency situation with a mortality rate of 2% to 10%. Therefore, initial risk stratification is important for proper management. We aimed to evaluate the role of contrast-enhanced multidetector computed tomography (MDCT) for risk stratification in patients with acute UGI bleeding in the emergency room (ER).

METHODS

This retrospective study included patients with UGI bleeding in the ER. Glasgow-Blatchford risk score-computed tomography (GBS-CT) was assessed using a combination of GBS and the MDCT scan scoring system.

RESULTS

Of the 297 patients with UGI bleeding, 124 (41.8%) underwent abdominal MDCT. Among them, 90.3% were classified as high-risk by GBS, and five patients died (4.0%). Rebleeding occurred in nine patients (7.3%). The high-risk GBS-CT group had significantly higher in-hospital mortality (10.5% in high-risk vs. 1.4% in moderate risk vs. 0% in low-risk, p = 0.049), transfusion amount (p &lt; 0.001), and endoscopic hemostasis (p &lt; 0.001) compared to the moderate- and low-risk groups.

CONCLUSION

Adding MDCT scans to the existing validated prognosis model when predicting the risk of UGI bleeding in patients in the ER plays a significant role in determining in-hospital mortality, transfusions, and the need for endoscopic hemostasis.

Comparison of Pre-Endoscopic C-WATCH Score with Established Risk Assessment Tools in Patients with Upper Gastrointestinal Bleeding

INTRODUCTION

Use of risk scores for early assessment of patients with upper gastrointestinal bleeding (UGIB) is recommended by various guidelines. We compared Cologne-WATCH (C-WATCH) score with Glasgow-Blatchford score (GBS), Rockall score (RS), and pre-endoscopic RS (p-RS).

METHODS

Patients with UGIB between January and December 2017 were retrospectively analyzed for 30-day mortality and composite endpoints risk of complications and need for intervention using areas under the receiver-operating characteristics curve (AUROC). Subgroup analysis was conducted for patients with UGIB on admission and in-hospital UGIB.

RESULTS

A total of 252 patients were identified (67.5% men, mean age 63.8 ± 14.9 years). In-hospital UGIB occurred in 49.6%. AUROCs for 30-day mortality, risk of complications, and need for intervention (not applicable to RS) were 0.684 (95% confidence interval [CI]: 0.606-0.763), 0.665 (95% CI: 0.594-0.735), and 0.694 (95% CI: 0.612-0.775) for C-WATCH score, 0.724 (95% CI: 0.653-0.796) and 0.751 (95% CI: 0.687-0.815) for RS, 0.652 (95% CI: 0.57-0.735), 0.653 (95% CI: 0.579-0.727), and 0.673 (95% CI: 0.602-0.745) for p-RS and 0.652 (95% CI: 0.572-0.732), 0.663 (95% CI: 0.592-0.734), and 0.752 (95% CI: 0.683-0.821) for GBS. RS outperformed pre-endoscopic scores in predicting risk of complications, while there were no significant differences between pre-endoscopic scores except GBS outperforming p-RS in predicting need for intervention. The subgroup analysis obtained similar results. Positive predictive values for patients with estimated low risk for all three endpoints (C-WATCH score ≤1, RS ≤2, p-RS <1, and GBS ≤1) were 89%, 69%, 78%, and 92%.

CONCLUSION

C-WATCH score performed similar to the established pre-endoscopic risk scores in patients with UGIB regarding relevant patient-related endpoints with no significant differences between both the subgroups.

Early lactate clearance for predicting outcomes in patients with gastrointestinal bleeding

BACKGROUND

Acute gastrointestinal bleeding (GI bleeding) can range from mild symptoms to life-threatening conditions that require emergency intervention. Therefore, it is important to first identify the high-risk and low-risk patients in the emergency department (ED).

AIMS

This study aimed to investigate the usefulness of a three-hourly interval for determining the lactate clearance, which is shorter than the time interval in previous studies, in order to predict the prognosis early in patients with GI bleeding.

METHODS

This retrospective study involved patients who visited for complaining of GI bleeding symptoms. Initial lactate levels were measured upon arrival at the ED and measured again 3 h later after performing initial resuscitation. And 3-h lactate clearance was calculated. Lactate and 3-h lactate clearance for predicting outcomes were evaluated by the area under the receiver operating characteristic (AUROC) curve.

RESULTS

A total of 104 patients were enrolled and 21 patients (20.2%) died in the hospital. Multivariate logistic regression showed that 3-h lactate clearance was a significant predictor of in-hospital mortality. The AUROC of 3-h lactate clearance for predicting in-hospital mortality was 0.756. The sensitivity and specificity were 66.67% and 75.90%. On combining lactate clearance, total bilirubin, and PTT, the AUROC was 0.899 for predicting in-hospital mortality.

CONCLUSIONS

This study validated that lactate clearance at three-hourly intervals is useful for early prediction of mortality and prognosis in patients with GI bleeding. It is important to perform not only an initial lactate measurement, but also a follow-up lactate measurement after initial resuscitation to check the lactate clearance.

Massive bleeding from gastric ulcer-induced splenic artery pseudoaneurysm successfully treated with transcatheter arterial embolization and surgery: a case report

BACKGROUND

Upper gastrointestinal bleeding (UGIB) is a routine medical emergency. The most common non-variceal cause is peptic ulcer disease, while a rare presentation is peptic ulcer-induced splenic artery pseudoaneurysm (SAP). Primary endoscopic treatment is generally attempted for UGIB; however, it sometimes fails when arterial etiology is present. In such cases, either transcatheter arterial embolization (TAE) or surgery is necessary, but the choice of treatment is controversial. We present a case that illustrates the utility of both approaches in a gastric ulcer-induced SAP.

CASE PRESENTATION

A 33-year-old male presented with hemorrhagic shock secondary to UGIB. The source of bleeding was identified as an SAP that was caused by a gastric ulcer. TAE enabled temporary bleeding control despite the patient's poor overall condition and limited blood transfusion capability. However, rebleeding occurred soon after stabilization. Ultimately, we performed proximal gastrectomy and splenic artery ligation, and the patient survived.

CONCLUSIONS

SAP is an uncommon occurrence, and angiographic information is important for correctly identifying the source of bleeding. The treatment for SAP bleeding is basically the same as for endoscopically unmanageable non-variceal UGIB, since TAE and surgery each have a different utility, depending on the situation. If surgery is performed, especially SA ligation and gastrectomy, it is important to consider the circulation of the spleen and residual stomach. Using TAE and laparotomy, we managed to save the life of the patient with massive hemorrhage under limited circumstances.

Transcatheter arterial embolization for gastrointestinal bleeding: Clinical outcomes and prognostic factors predicting mortality

We evaluated clinical outcome and prognostic factors predicting mortality of transcatheter arterial embolization (TAE) for acute gastrointestinal (GI) bleeding. Fifty-nine patients (42 men, 17 women; mean age 66.1 ± 17.0) who underwent 59 TAE procedures for GI bleeding during 2013-2018 were retrospectively evaluated. Clinical outcomes included technical success, adverse events, and rebleeding and mortality rate within 30 days. The technical success rate was 100%. Angiography showed contrast extravasation in 41 (69.5%) patients and indirect signs of bleeding in 16 (27.1%) patients. Two (3.4%) patients underwent prophylactic embolization. TAE-related adverse events occurred in 7 (11.9%) patients; adverse events were more common for mid GI or lower GI bleeding than for upper GI bleeding (22.6% vs 0%, P = 0.007). Rebleeding within 30 days was observed in 22 (37.3%) patients after TAE. Coagulopathy was a prognostic factor for rebleeding (odds ratio [OR] = 3.53, 95% confidence interval 1.07-11.67, P = .038). Mortality within 30 days occurred in 11 (18.6%) patients. Coagulopathy (OR = 24, 95% confidence interval 2.56-225.32, P = .005) was an independent prognostic factor for mortality within 30 days. TAE is an effective, safe, and potentially lifesaving procedure for GI bleeding. If possible, coagulopathy should be corrected before TAE as it may reduce rebleeding and mortality.
