Predictors of a variceal source among patients presenting with upper gastrointestinal bleeding

Assessment, Resuscitation and Medical Management of Variceal and Nonvariceal Gastrointestinal Bleeding

Upper gastrointestinal bleeding (UGIB) continues to be an important cause for emergency room visits and carries significant morbidity and mortality. Early resuscitative measures form the basis of the management of patients presenting with UGIB and can improve the outcomes of such patients including lowering mortality. In this review, using an evidence-based approach, we discuss the initial assessment and resuscitation of patients presenting with UGIB including identifying clues from history and physical examination to confirm UGIB, preendoscopic risk assessment tools, the role of early fluid resuscitation, utilization of blood products, use of pharmacologic interventions, and the optimal timing of endoscopy.

Healthcare Disparities and Upper Gastrointestinal Bleeding: Exploring the Linkages

Introduction Upper gastrointestinal bleeding (UGIB) refers to blood loss from a gastrointestinal (GI) source proximal or above the ligament of Treitz. Health equity means giving everyone an equal chance to achieve optimal health by addressing injustices, overcoming barriers, and eliminating health disparities. Healthcare providers must analyze racial and ethnic disparities in UGIB management to ensure all patients receive equal care. Identifying risk factors in specific populations leads to tailored interventions that improve outcomes. Our study aims to examine trends and identify disparities in upper gastrointestinal bleeding across races and ethnicities to promote health equity. Methods Retrospective data on upper gastrointestinal bleeding from June 2009 to June 2022 were collected and categorized into five groups based on race. The baseline characteristics of each group were matched to ensure equitable comparison. A joinpoint regression model was used to compare incidence trends, identifying potential healthcare disparities for different racial/ethnic groups over time. Patients aged 18-75 who suffered from upper gastrointestinal bleeding at Nassau University Medical Center in New York from 2010 to 2021 were selected, excluding those with incomplete baseline comorbidity information. Results This study examined 5103 cases of upper gastrointestinal bleeding, with 41.9% female. The cohort was diverse, with 29.4% African American, 15.6% Hispanic, 45.3% White, 6.8% Asian, and 2.9% of other races. Data were split into two groups; 49.9% occurred between 2009 and 2015 and 50.1% between 2016 and 2022. Findings showed increased UGIB among Hispanics and decreased bleeding among Asians during 2016-2021 compared to 2009-2015. However, no significant difference was found for African Americans, Whites, and other races. In addition, Hispanics had a rise in the annual percentage change (APC) rate, whereas Asians had a decrease. Conclusion Our study examined trends in upper gastrointestinal bleeding and potential healthcare disparities across races and ethnicities. Our findings highlight an increased incidence of UGIB in Hispanics and a decreased incidence in Asians. Additionally, we identified a significant increase in the annual percentage change rate in Hispanics and a decrease in Asians over time. Our study underscores the importance of identifying and addressing disparities in UGIB management to promote health equity. Future research can build on these findings to develop tailored interventions that improve patient outcomes.

Validation of a decision rule to predict patients at low risk of variceal upper gastrointestinal hemorrhage

BACKGROUND

Determining the likelihood of a variceal versus nonvariceal source of upper gastrointestinal bleeding (UGIB) guides ED therapy, but can be difficult to determine on clinical grounds. A simple decision rule, using only platelet and international normalized ratio (INR) values, was previously derived in a single center and had high sensitivity (97%). We sought to validate this decision rule using multi-center data.

MATERIALS AND METHODS

We performed this decision rule validation using data collected from 21 Canadian hospitals, comprising 2020 patients. The parent study enrolled patients aged ≥18 years at participating hospitals with nonvariceal or variceal UGIB from January 2004 through May 2005. To validate the existing decision rule, we computed the test characteristics of the rule on this study population. The existing decision rule, in order to predict patients at low risk for variceal hemorrhage, is designed to be highly sensitive for variceal UGIB. In the previously derived rule, patients are not low risk if either is present: INR ≥1.3 or platelet count ≤200 × 10⁹/L. We additionally added a third common-sense criterion to the decision rule in a separate analysis: whether the patient has previously had variceal hemorrhage.

RESULTS

2001 patients were eligible for analysis, including 214 (10.7%) with a variceal source of gastrointestinal hemorrhage. Median age was 69 (IQR 55-79), and 764 (38%) were women. The two-step rule correctly identified 204 of the 214 (95.3%) patients with variceal hemorrhage; adding prior variceal hemorrhage as a variable identified 5 more patients (209/214 [97.7%]). Of the 2001 patients, 953 (47%) would have been classified as low risk for variceal hemorrhage; of these patients, 5 (0.5%) experienced variceal hemorrhage. The sensitivity of the rule in this validation cohort was 95.3% (95% CI 91.6-97.7%), with a negative likelihood ratio of 0.09 (95% CI 0.05-0.16). Adding prior variceal hemorrhage increased sensitivity to 97.7% (95% CI 94.6-99.2%), with a negative likelihood ratio of 0.04 (95% CI 0.02-0.11).

CONCLUSION

We have validated a simple decision rule to identify patients at low risk for variceal UGIB. This two-step (three-step if prior history of variceal hemorrhage is known) rule is simple to use, and may enable safe deferment of unnecessary or harmful therapies.

Is upper gastrointestinal bleeding still a life-threatening condition?

Background: Upper gastrointestinal bleeding is a common clinical problem and one of the main reasons for emergency hospitalization. It is associated with an overall mortality rate of 2% to 13%, despite advances in medical therapy. First-choice management is conservative treatment with endoscopic hemostasis. Aim of the study: The aim of the study was to examine the epidemiological and clinical characteristics of patients with upper gastrointestinal bleeding with a focus on the course of hospitalization based on the etiology Material and methods: A retrospective study was conducted in the Department of Surgery at the 4th Military Teaching Hospital in the years 2011–2016, comprising a total of 200 hospitalizations. 150 (75%) of the study group were men, and the mean age was 63.6±15.8 years. Results: Patients most frequently presented with melena (n=105; 53.1%) and hematemesis (n=79; 40%) or coffee ground vomiting (n=57; 28.7%). . 138 (69%) of hemorrhages were managed with endoscopic hemostasis, and in 43 (21.5%) of cases conservative treatment was adequate. In 12 (6%) of cases, laparotomy was the first-choice therapy and in 7 (3.5%) cases, surgery was performed after an attempt at endoscopic treatment had failed. The sources of bleeding were: gastric ulcer – 58 (29%), duodenal ulcer – 48 (24%), esophageal varices – 31 (15.5%), gastric tumor – 15 (7.5%), Mallory-Weiss syndrome – 10 (5%), and Dieulafoy’s lesion – 3 (1.5%). 16 (8%) of the hospitalizations were fatal. Conclusions: Upper gastrointestinal bleeding still has a high mortality rate (8%). It more frequently affects men and the elderly. Gastric and duodenal ulcers are the most common etiologies of bleeding. Esophageal varices and neoplasms are also a significant source of bleeding. Despite the progress in the pharmacological treatment of peptic ulcers, the complications resulting from gastrointestinal bleeding continue to be a serious clinical problem.

Comparison of clinical outcomes between variceal and non-variceal gastrointestinal bleeding in patients with cirrhosis

BACKGROUND AND AIM

Acute upper gastrointestinal bleeding (UGIB) in cirrhosis is associated with significant morbidity and mortality and can be classified as acute variceal bleeding (AVB) or non-variceal bleeding (NVB). Differences in mortality, hospital length of stay (LOS), and 30-day readmission have yet to be determined. As such, the study aimed to evaluate differences in these clinical outcomes in cirrhotic patients admitted with UGIB.

METHODS

This retrospective study included all cirrhotic patients hospitalized for UGIB who underwent upper endoscopy from July 2014 to July 2016. AVB was defined as the presence of varices on endoscopy with high-risk stigmata such as cherry-red spots. Mortality, intensive care unit admission, hospital LOS, and 30-day hospital readmission were recorded and compared among patients with AVB and NVB.

RESULTS

A total of 116 patients with cirrhosis were included, 73 with AVB and 43 with NVB. Patients with NVB were older than those with AVB (60.4 ± 11.1 vs 55.0 ± 9.5, P = 0.006) whereas patients with AVB were more likely to have known esophageal varices (64.4% vs 37.2%, P = 0.007). Patients with AVB and NVB had similar mortality (15.1% vs 9.3%, P = 0.57), hospital LOS (4.9, interquartile range: 3.6-6.9 days vs 5.0, interquartile range: 2.7-8.3 days), and 30-day readmission rates (19.2% vs 30.2%, P = 0.18). Severity of clinical presentation was associated with increased LOS and overall mortality, including the need for intensive care unit admission, but these were not associated with 30-day readmission rates.

CONCLUSION

There were no differences in clinical outcomes, including mortality, in cirrhotic patients admitted with AVB and NVB.

Patient Presentation, Risk Stratification, and Initial Management in Acute Lower Gastrointestinal Bleeding

The approach to lower gastrointestinal bleeding (LGIB) has evolved over the last few years to incorporate a multidisciplinary management strategy. Although the causes of LGIB vary depending on the age and comorbid conditions of patients, the initial resuscitation and principles of optimizing patients' condition before endoscopic evaluation, when appropriate, are the cornerstones to clinical care. The role of risk stratification is to triage patients as well as to mobilize health care resources based on predicted outcomes. Individualized management according to patients' comorbid conditions has been a focus in most recent guidelines.

Guidelines for endoscopic management of non-variceal upper gastrointestinal bleeding

Japan Gastroenterological Endoscopy Society (JGES) has compiled a set of guidelines for endoscopic management of non-variceal upper gastrointestinal bleeding using evidence-based methods. The major cause of non-variceal upper gastrointestinal bleeding is peptic gastroduodenal ulcer bleeding. As a result, these guidelines mainly focus on peptic gastroduodenal ulcer bleeding, although bleeding from other causes is also overviewed. From the epidemiological aspect, in recent years in Japan, bleeding from drug-related ulcers has become predominant in comparison with bleeding from Helicobacter pylori (HP)-related ulcers, owing to an increase in the aging population and coverage of HP eradication therapy by national health insurance. As for treatment, endoscopic hemostasis, in which there are a variety of methods, is considered to be the first-line treatment for bleeding from almost all causes. It is very important to precisely evaluate the severity of the patient's condition and stabilize the patient's vital signs with intensive care for successful endoscopic hemostasis. Additionally, use of antisecretory agents is recommended to prevent rebleeding after endoscopic hemostasis, especially for gastroduodenal ulcer bleeding. Eighteen statements with evidence and recommendation levels have been made by the JGES committee of these guidelines according to evidence obtained from clinical research studies. However, some of the statements that are supported by a low level of evidence must be confirmed by further clinical research.

Alcohol Abuse Increases Rebleeding Risk and Mortality in Patients with Non-variceal Upper Gastrointestinal Bleeding

BACKGROUND

No current data are available on rebleeding and mortality risk in patients who use alcohol excessively and are admitted for non-variceal upper gastrointestinal bleeding (NVUGIB). This information could help in planning interventions and follow-up protocols for these patients.

AIM

This study provides contemporary data on the long-term outcome after first-time NVUGIB in alcohol abusers (AAs) compared to non-abusers (NAs).

METHODS

Consecutive patients hospitalized for their first acute gastrointestinal bleeding from 2009 through 2011 were retrospectively recorded and categorized as AA or NA. Risk factors for one-year mortality and rebleeding were identified, and patients were further monitored for long-term mortality until 2015.

RESULTS

Alcohol abuse was identified in 19.7% of patients with NVUGIB (n = 518). The one-year rebleeding rate was 16.7% in AAs versus 9.1% in NAs (P = 0.027). Alcohol abuse was associated with a twofold increase in rebleeding risk (P = 0.025); the risk especially increased 6 months after the initial bleeding. The study groups did not differ significantly in 30-day (6.0%) or one-year mortality rates (20.5%). However, there was a tendency for higher overall mortality in AAs than NAs after adjustment of comorbidities.

CONCLUSION

AAs with NVUGIB are at high risk of rebleeding, and mortality is increased in AA patients. A close follow-up strategy and long-term proton pump inhibitor therapy are recommended for AA patients with peptic ulcer or esophagitis.

Impact of ethnicity in upper gastrointestinal hemorrhage

GOALS

To examine ethnicity's role in the etiology and outcome of upper gastrointestinal hemorrhage (UGIH).

BACKGROUND

UGIH is a serious condition with considerable associated morbidity and mortality.

MATERIALS AND METHODS

We analyzed 2196 patients admitted with acute UGIH between January 2006 and February 2012. Complete clinical data were gathered prospectively and entered into our GI Bleed Registry, which captures demographic and clinical variables. Results were analyzed using the χ² analyses and the analysis of variance techniques with Tukey multiple comparisons.

RESULTS

Among 2196 patients, 620 (28%) were black, 625 (29%) white, 881 (40%) Hispanic, and 70 (3%) were members of other ethnicities. Gastroduodenal ulcers (25%), esophageal varices (25%), and esophagitis (12%) were the most frequently identified causes of UGIH. Blacks experienced a high rate of gastroduodenal ulcers (199/620), whereas Hispanics most commonly had esophageal varices. In all ethnicities, the most common cause of bleeding in patients younger than 35 or older than 65 years was gastroduodenal ulcer disease. However, among patients aged 35 to 64 years, there were differences in the etiology of UGIH. Blacks aged 50 to 64 years frequently experienced gastroduodenal ulcers, whereas Hispanics aged 35 to 49 years typically had esophageal varices. Rebleeding rates were significantly lower in whites (5.8%) than in Hispanics (9.9%) or blacks (8.7%) (P=0.02).

CONCLUSIONS

By examining a diverse population, we conclude that UGIH may follow trends. Hispanics were likely to have esophageal varices and higher rebleeding rates, whereas blacks were likely to have ulcers and the highest mortality. Whites were equally likely to have ulcers or varices, but a lower rate of rebleeding.

Multidisciplinary management strategies for acute non-variceal upper gastrointestinal bleeding

BACKGROUND

The modern management of acute non-variceal upper gastrointestinal bleeding is centred on endoscopy, with recourse to interventional radiology and surgery in refractory cases. The appropriate use of intervention to optimize outcomes is reviewed.

METHODS

A literature search was undertaken of PubMed and the Cochrane Central Register of Controlled Trials between January 1990 and April 2013 using validated search terms (with restrictions) relevant to upper gastrointestinal bleeding.

RESULTS

Appropriate and adequate resuscitation, and risk stratification using validated scores should be initiated at diagnosis. Coagulopathy should be corrected along with blood transfusions, aiming for an international normalized ratio of less than 2·5 to proceed with possible endoscopic haemostasis and a haemoglobin level of 70 g/l (excluding patients with severe bleeding or ischaemia). Prokinetics and proton pump inhibitors (PPIs) can be administered while awaiting endoscopy, although they do not affect rebleeding, surgery or mortality rates. Endoscopic haemostasis using thermal or mechanical therapies alone or in combination with injection should be used in all patients with high-risk stigmata (Forrest I-IIb) within 24 h of presentation (possibly within 12 h if there is severe bleeding), followed by a 72-h intravenous infusion of PPI that has been shown to decrease further rebleeding, surgery and mortality. A second attempt at endoscopic haemostasis is generally made in patients with rebleeding. Uncontrolled bleeding should be treated with targeted or empirical transcatheter arterial embolization. Surgical intervention is required in the event of failure of endoscopic and radiological measures. Secondary PPI prophylaxis when indicated and Helicobacter pylori eradication are necessary to decrease recurrent bleeding, keeping in mind the increased false-negative testing rates in the setting of acute bleeding.

CONCLUSION

An evidence-based approach with multidisciplinary collaboration is required to optimize outcomes of patients presenting with acute non-variceal upper gastrointestinal bleeding.

Nurses' experiences with catastrophic upper gastrointestinal bleeding in patients with hepatocellular carcinoma: a qualitative study

PURPOSE

To explore how nurses experienced catastrophic upper gastrointestinal bleeding in hepatocellular carcinoma (HCC) patients.

METHODS

A qualitative descriptive method was used. Data were collected by semi- structured interviews. Twenty-one registered nurses who had taken care of HCC patients with catastrophic upper gastrointestinal bleeding were purposely recruited from the Department of Hepatobiliary Cancer, Tianjin Medical University Cancer Institute and Hospital located in mainland China.

RESULTS

Four themes explicated from the study were: feelings expressed during the process of rescuing the lives of patients, feelings expressed from succeeding or failing to save the lives of patients, feelings expressed from family members response to nurses' actions, the impact of the experience on the personal life, work and philosophy of life of the nurse subjects.

CONCLUSIONS

The findings of this study indicate that it is necessary for nursing leaders to take effective measures to improve nurses' nursing skills, to provide more education in care of the dying, to offer nurses services that address their psychosocial health and to provide them with emotional support.
