Upper gastrointestinal bleeding risk scores: Who, when and why?

Preclinical study of a novel ingestible bleeding sensor for upper gastrointestinal bleeding

BACKGROUND/AIMS

Upper gastrointestinal bleeding (UGIB) is a life-threatening condition that necessitates early identification and intervention and is associated with substantial morbidity, mortality, and socioeconomic burden. However, several diagnostic challenges remain regarding risk stratification and the optimal timing of endoscopy. The PillSense System is a noninvasive device developed to detect blood in patients with UGIB in real time. This study aimed to assess the safety and performance characteristics of PillSense using a simulated bleeding model.

METHODS

A preclinical study was performed using an in vivo porcine model (14 animals). Fourteen PillSense capsules were endoscopically placed in the stomach and blood was injected into the stomach to simulate bleeding. The safety and sensitivity of blood detection and pill excretion were also investigated.

RESULTS

All the sensors successfully detected the presence or absence of blood. The minimum threshold was 9% blood concentration, with additional detection of increasing concentrations of up to 22.5% blood. All the sensors passed naturally through the gastrointestinal tract.

CONCLUSION

This study demonstrated the ability of the PillSense System sensor to detect UGIB across a wide range of blood concentrations. This ingestible device detects UGIB in real time and has the potential to be an effective tool to supplement the current standard of care. These favorable results will be further investigated in future clinical studies.

The Reduction of After-Hours and Weekend Effects in Upper Gastro-intestinal Bleeding Mortality During the COVID-19 Pandemic Compared to the Pre-Pandemic Period

Background

In upper gastrointestinal bleeding (UGIB), admissions after normal working hours and during weekends may be associated with increased mortality.

Aim

To assess the evolution of the after-hours and weekend effects during the COVID-19 pandemic as a result of progressive improved management despite management challenges during the pandemic.

Methods

We performed an observational study of patients admitted for UGIB at a tertiary academic center between March 2020 and December 2021, compared to the corresponding timeframe before the pandemic. Admissions were assessed based on regular hours versus after-hours and weekdays versus weekends. We stratified patients based on demographic data, etiology, prognostic scores, the time between symptom onset and admission, as and between admission and endoscopy. The outcomes included mortality, rebleeding rate, the requirement for surgery and transfusion, and hospitalization days.

Results

802 cases were recorded during the pandemic, and 1006 cases before the pandemic. The overall mortality rate was 12.33%. Patients admitted after hours and during weekends had a higher mortality rate compared to those admitted during regular hours and weekdays (15.18% versus 10.22%, and 15.25% versus 11.16%), especially in cases of non-variceal bleeding. However, the difference in mortality rates was reduced by 2/3 during the pandemic, despite the challenges posed by COVID-19 infection. This suggests that there was an equalization effect of care in UGIB, regardless of the admission time. The differences observed in mortality rates for after-hours and weekend admissions seem to be primarily related to a higher proportion of patients who did not undergo endoscopy, while the proportion of severe cases remained similar. Blood requirements, hospital days, and rebleeding rate were similar between the two groups.

Conclusion

Admissions during weekends and after-hours have been associated with increased mortality, particularly in cases of non-variceal bleeding. However, the impact of this association was significantly reduced during the pandemic.

AIMS65, Glasgow-Blatchford bleeding score and modified Glasgow-Blatchford bleeding score in predicting outcomes of upper gastrointestinal bleeding: An accuracy and calibration study

BACKGROUND

Albumin, international normalized ratio (INR), mental status, systolic blood pressure, age >65 years (AIMS65), Glasgow-Blatchford bleeding score (GBS) and modified GBS (mGBS) are three pre-endoscopy scoring systems used in the risk stratification of upper gastrointestinal bleeding (UGIB). The utility of such scoring systems in a population is estimated by their accuracy and calibration in the population. We aimed at validating and comparing the accuracy of the three scoring systems in predicting clinical outcomes including in-hospital mortality, need for blood transfusion, endoscopic treatment and rebleeding risk.

METHOD

We conducted a single-center, retrospective cohort study on patients with UGIB at a tertiary care center in India over 12 months. Clinical and laboratory data was collected from all patients admitted with UGIB. All patients were risk stratified using AIMS65, GBS and mGBS. The clinical outcome examined were: in-hospital mortality, requirement of blood transfusion, need for endoscopic treatment and rebleeding during hospital stay. The area under receiver-operating curve (AUROC) was calculated to assess the performance and calibration curves (Hosmer-Lemeshow goodness of fit curve) were plotted to examine how accurately the model describes the data of all three scoring systems.

RESULTS

Total 260 patients were included in the study, of which 236 (90.8%) were males. As many as 144 (55.4%) patients required blood transfusion and 64 (30.8%) required endoscopic treatment. While the incidence of rebleeding was 7.7%, in hospital mortality was 15.4%. Of 208 who underwent endoscopy, the most common causes identified were varices (49%) and gastritis (18.2%), followed by ulcer (11%), Mallory-Weiss tear (8.1%), portal hypertensive gastropathy (6.7%), malignancy (4.8%) and esophageal candidiasis (1.9%). The median AIMS65 score was 1, GBS 7 and mGBS 6. The area under curve (AUROC) for AIMS65, GBS and mGBS was (0.77, 0.73,0.70), (0.75, 0.82,0.83), (0.56, 0.58,0.83), (0.81, 0.94,0.53) for in-hospital mortality, blood transfusion requirement, endoscopic treatment and rebleeding prediction, respectively.

CONCLUSION

GBS and mGBS are superior to AIMS65 in predicting the requirement of blood transfusion and rebleeding risk, whereas in-hospital mortality was better predicted by AIMS 65. Both scores performed poorly in predicting the need of endoscopic treatment. An AIMS65 of 0,1 and a GBS of ≤ 1 are not associated with significant adverse events. A poor calibration of the scores in our population points to the lack of generalizability of these scoring systems.

A Nomogram Model for Prediction of Mortality Risk of Patients with Dangerous Upper Gastrointestinal Bleeding: A Two-center Retrospective Study

OBJECTIVE

This study aimed to establish a nomogram model to predict the mortality risk of patients with dangerous upper gastrointestinal bleeding (DUGIB), and identify high-risk patients who require emergent therapy.

METHODS

From January 2020 to April 2022, the clinical data of 256 DUGIB patients who received treatments in the intensive care unit (ICU) were retrospectively collected from Renmin Hospital of Wuhan University (n=179) and the Eastern Campus of Renmin Hospital of Wuhan University (n=77). The 179 patients were treated as the training cohort, and 77 patients as the validation cohort. Logistic regression analysis was used to calculate the independent risk factors, and R packages were used to construct the nomogram model. The prediction accuracy and identification ability were evaluated by the receiver operating characteristic (ROC) curve, C index and calibration curve. The nomogram model was also simultaneously externally validated. Decision curve analysis (DCA) was then used to demonstrate the clinical value of the model.

RESULTS

Logistic regression analysis showed that hematemesis, urea nitrogen level, emergency endoscopy, AIMS65, Glasgow Blatchford score and Rockall score were all independent risk factors for DUGIB. The ROC curve analysis indicated the area under curve (AUC) of the training cohort was 0.980 (95%CI: 0.962-0.997), while the AUC of the validation cohort was 0.790 (95%CI:0.685-0.895). The calibration curves were tested for Hosmer-Lemeshow goodness of fit for both training and validation cohorts (P=0.778, P=0.516).

CONCLUSION

The developed nomogram is an effective tool for risk stratification, early identification and intervention for DUGIB patients.

Performance of Six Clinical Physiological Scoring Systems in Predicting In-Hospital Mortality in Elderly and Very Elderly Patients with Acute Upper Gastrointestinal Bleeding in Emergency Department

Background and Objectives: The aim of this study is to compare the performance of six clinical physiological-based scores, including the pre-endoscopy Rockall score, shock index (SI), age shock index (age SI), Rapid Acute Physiology Score (RAPS), Rapid Emergency Medicine Score (REMS), and Modified Early Warning Score (MEWS), in predicting in-hospital mortality in elderly and very elderly patients in the emergency department (ED) with acute upper gastrointestinal bleeding (AUGIB). Materials and Methods: Patients older than 65 years who visited the ED with a clinical diagnosis of AUGIB were enrolled prospectively from July 2016 to July 2021. The six scores were calculated and compared with in-hospital mortality. Results: A total of 336 patients were recruited, of whom 40 died. There is a significant difference between the patients in the mortality group and survival group in terms of the six scoring systems. MEWS had the highest area under the curve (AUC) value (0.82). A subgroup analysis was performed for a total of 180 very elderly patients (i.e., older than 75 years), of whom 27 died. MEWS also had the best predictive performance in this subgroup (AUC, 0.82). Conclusions: This simple, rapid, and obtainable-by-the-bed parameter could assist emergency physicians in risk stratification and decision making for this vulnerable group.

An intelligent intestinal bleeding diagnosis and treatment capsule system based on color recognition

To our best knowledge, there are no non-invasive and painless means for the diagnosis and treatment of intestinal bleeding as of now, especially the segment of intestine that cannot be reached by endoscopy. We proposed an intelligent intestinal bleeding diagnosis and treatment capsule (IBDTC) system for the first time to diagnose and treat intestinal bleeding with low power consumption, estimated to be about 2.16mW. A hue-saturation-light (HSL) color space method was applied to diagnose bleeding according to H (hue) values of the film dyed by blood. A MEMS-based micro-igniter works as the critical component of the micro-thruster that houses the propellant (74.6% potassium nitrate, 11.9% sulfur, 13.5% charcoal) and the detonating agent (dinitrodiazophenol), to help release drug. Bleeding detection and ignition tests were performed to justify its feasibility and reliability. Results demonstrated that the bleeding diagnosis module of the IBDTC can effectively detect bleeding and the micro-igniter can successfully ignite the propellant. Owing to its simplicity and intelligence, the IBDTC system will pave a way for future accurate treatment of small intestinal bleeding with no injury, no pain, no complicated supporting equipment, no need for in vitro operation and positioning.

Acute gastrointestinal bleeding: A comparison between variceal and nonvariceal gastrointestinal bleeding

Acute upper gastrointestinal bleeding (UGIB) is a typical medical emergency, with an incidence of 84 to 160 cases per 100,000 individuals and a mortality rate of approximately 10%. This study aimed to identify all cases of UGIB hospitalized in a tertiary gastroenterology department, to identify possible predictive factors involved in rebleeding and mortality, potential associations between different elements and the severity of bleeding, and the differences between the upper digestive hemorrhage due to nonvariceal and variceal bleeding. This was an observational, retrospective study of patients with UGIB admitted to the tertiary Department of Gastroenterology between January 2013 and December 2020. A total of 1499 patients were enrolled in the study. One thousand four hundred and ninety-nine patients were hospitalized for 7 years with active upper digestive hemorrhage, 504 variceal bleeding, and 995 nonvariceal bleeding. When comparing variceal with nonvariceal bleeding, in nonvariceal bleeding, the mean age was higher, similar sex, higher mortality rate, higher rebleeding rate, and higher hemorrhagic shock rate. Endoscopy treatment was also performed more frequently in variceal bleeding than in nonvariceal bleeding. Severe anemia was found more frequently in patients with variceal bleeding. The mortality rate was 10% in the entire study group, which was not significantly different between the 2 batches. However, the rebleeding rate is higher in patients with variceal gastrointestinal bleeding.

International Normalized Ratio-to-Albumin Ratio as a Novel Marker of Upper Gastrointestinal Bleeding Severity

Introduction

Upper gastrointestinal bleeding (UGIB) is a potentially life-threatening gastrointestinal emergency, and effective management depends on early risk stratification. The Glasgow–Blatchford and Rockall scores are commonly used prognostic measures for UGIB, although these scoring systems are relatively difficult to apply in early emergency settings. AIMS65 with five items, albumin, international normalized ratio, mental status, systolic blood pressure, and age (>65 years), showed efficacy in predicting long-term hospitalization and mortality. This study aimed to investigate the usefulness of the prothrombin time-international normalized ratio-to-albumin ratio (PTAR) in the emergency room for early UGIB risk stratification.

Methods

We retrospectively examined patients who visited a tertiary academic hospital's emergency department (ED) with UGIB as the chief presentation between January 2019 and December 2020. The cutoff values and diagnostic accuracies of the PTAR, Glasgow–Blatchford score, AIMS65 score, pre-endoscopy, and complete Rockall score were analyzed, and the performance of the PTAR was compared with that of other risk stratification methods. In total, 519 patients were enrolled: 163 patients were admitted in the intensive care unit (ICU) and 35 died during admission. Multiple logistic regression analyses confirmed the association of the PTAR with ICU admission and mortality. The adjusted odd ratio (aOR) of the PTAR for ICU admission care was 8.376 (2.722–25.774), and the aOR of the PTAR for mortality was 27.846 (8.701–89.116).

Conclusions

The PTAR measured in the ED is an independent factor related to ICU admission and mortality in patients with UGIB. Using ED blood laboratory results, which are reported relatively quickly and are easy to acquire and calculate, the PTAR can be used as a risk stratification marker in the early emergency setting.

Peri-Ulcerative Mucosal Inflammation Appearance is an Independent Risk Factor for 30-Day Rebleeding in Patients with Gastric Ulcer Bleeding: A Multicenter Retrospective Study

Aim

The aim of this study was to identify clinical endoscopic indicators related to peri-ulcerative mucosal inflammation and to analyze whether the degree of peri-ulcerative mucosal inflammation appearance is an independent risk factor for gastric ulcer rebleeding.

Methods

We conducted a retrospective study that included patients with gastric ulcer bleeding who were hospitalized at three medical centers in China from January 1, 2016 to December 31, 2019. Ulcer rebleeding that occurred within 30 days of successful initial hemostasis was analyzed to determine whether this event was related to the degree of peri-ulcerative mucosal inflammation appearance or other mucosal inflammation-related factors.

Results

We enrolled 1111 patients and determined that GBS-Rebleeding-ROC (P<0.001), age (P=0.01), use of NSAIDs (P=0.001), bile reflux (P<0.001), and Helicobacter pylori (P<0.001) are all risk factors for peri-ulcerative mucosal inflammation appearance. Through multivariate analysis, we determined that severe peri-ulcerative mucosal inflammation appearance (P=0.002) was an independent risk factor for ulcer rebleeding within 30 days. Finally, we developed a risk assessment model using factors associated with mucosal inflammation that may be useful for early prediction of rebleeding.

Conclusion

The risk factors for peri-ulcerative mucosal inflammation appearance were identified. Severe peri-ulcerative mucosal inflammation appearance is an independent risk factor for ulcer rebleeding.

Platelet Count/Spleen Thickness Ratio and the Risk of Variceal Bleeding in Cirrhosis With Esophagogastric Varices

Introduction

The platelet count/spleen thickness ratio (PC/ST ratio) is associated with the grade of esophagogastric varices (EGV) in cirrhotic patients, but little is known about its relationship with esophagogastric variceal bleeding (EGVB). The aim of this study was to investigate the association between the PC/ST ratio and the risk of EGVB within 1 year in cirrhotic patients.

Methods

A total of 1,354 patients with cirrhosis who had EGV were enrolled in this cohort study. A logistic regression model was used to determine the association between the PC/ST ratio and the risk of EGVB within 1 year in patients with cirrhosis by adjusting the PC/ST ratio with all the important clinical variables and confounders.

Results

The quartile values of the PC/ST ratio were 1.01, 1.36, and 1.98, respectively. The PC/ST ratio was an independent risk factor for variceal bleeding in cirrhotic patients with moderate or severe EGV. After adjusting for multiple variables, the relationship was still unchanged. The odds ratios of the first EGVB in these patients were 5.07-fold at non-adjustment and 3.28-fold after multivariate adjustment. The odds ratios of rebleeding in these patients from the lowest to the highest quartile were 2.34-fold at non-adjustment and 2.01-fold after multivariable adjustment. The PC/ST ratio ≤ 1.36 elevated the 1-year risk of first-time variceal bleeding or rebleeding in cirrhotic patients with moderate or severe EGV (All P &lt; 0.05).

Conclusion

The PC/ST ratio ≤ 1.36 is an independent risk factor for the onset of first bleeding or rebleeding in cirrhotic patients with moderate or severe EGV.

A Comparative Analysis of Risk Scoring Systems in Predicting Clinical Outcomes in Upper Gastrointestinal Bleed

Background

Upper gastrointestinal bleed (UGIB) is a life-threatening condition that presents as hematemesis (fresh blood), coffee-ground vomiting, or melena. Multiple scoring systems are developed to predict different clinical outcomes, which are important to managing UGIB and are essential to determining low and high-risk patients. The study aimed to compare the sensitivity and specificity of risk scoring systems and their optimum cut-off values in the assessment of UGIB.

Methods

The prospective cross-sectional study included patients (N = 81) with acute UGIB. Four different proposed scores [Glasgow-Blatchford score (GBS), AIMS65, pre-endoscopic Rockall, and full Rockall scoring system] were used for evaluating patients with UGIB. The optimum cut-off values of these risk scores were used to predict the clinical outcomes.

Results

The AIMS65 score [Area Under the Receiver Operating Characteristic curve (AUROC): 0.91, cut-off: >1, sensitivity: 100%, specificity: 76.62%] and pre-Rockall were similar (AUROC: 0.91, cut-off: >0, sensitivity: 100%, specificity: 93.51%) at predicting mortality. The GBS (cut-off: >9, AUROC: 0.79, sensitivity: 69.23, specificity: 87.50) and AIMS65 scores (cut-off: >0, AUROC: 0.67, sensitivity: 72.31, specificity: 62.5) were good predictors of need for ICU care.

Conclusion

GBS was superior in predicting categorization into high risk and low risk, and endoscopic intervention, blood transfusion, and intensive care unit (ICU) care in UGIB patients. Pre-Rockall score and AIMS65 score were similar in predicting the mortality rate in UGIB.

The effectiveness of Glasgow-Blatchford Score in early risk assessment of hemodialysis patients

In the emergency departments (ED), the incidence of admission is increasing gradually due to gastrointestinal system (GIS) complications of hemodialysis (HD) patients. With this increasing number of patients, there are many classification systems developed in early risk assessment before endoscopy. In this study, we aimed to evaluate the Glasgow-Blatchford Score's (GBS) effectiveness in HD patients with suspected GIS hemorrhage in the ED.The files of 169 patients who received HD treatment were retrospectively reviewed. 64 patients who were examined and treated for reasons other than GIS hemorrhage in the ED were excluded, and the files of a total of 105 were analyzed retrospectively. The demographic characteristics and laboratory values of the patients were recorded from the patient files. When the patients were evaluated according to GBS parameters, a significant difference was found between the two groups in terms of pulse pressure, systolic blood pressure, hemoglobin value, melena, and accompanying comorbid diseases (p < 0.05). Of the 16 patients who presented to the ED due to syncope, 2 were in the GIS hemorrhage (+) group, and 14 patients were in the control group. In this study, we aimed to show that the increase in the number of admissions in the ED due to complications secondary to HD treatment and the accompanying serious changes in laboratory parameters may cause misleading results in patients with suspected GIS hemorrhage, and it is necessary to plan comprehensive and multi-center studies on new alternative scoring systems to GBS in specific patient groups such as HD patients.

Prediction of adverse outcomes using non-endoscopic scoring systems in patients over 80 years of age who present with the upper gastrointestinal bleeding in the emergency department

BACKGROUND

The emergency department (ED) admission rate for elderly patients with non-variceal upper gastrointestinal bleeding (UGIB) is increasing. The AIMS65 and Glasgow-Blatchford score (GBS) are two distinct scoring systems proposed to predict in-hospital and post-discharge mortality, length of stay (LOS), and health-related costs in these patients. The objective of the present study is to evaluate the accuracy of these scoring systems, in conjunction with the Charlson comorbidity index (CCI), to predict 30-day mortality and LOS in UGIB patients who are 80 years of age or older METHODS: A retrospective analysis was undertaken of 182 patients with non-variceal UGIB who were admitted to the ED of Canakkale Onsekiz Mart University Hospital. The AIMS65, GBS, and CCI scores were calculated and adverse patient outcomes were assessed.

RESULTS

The mean age of patients was 85.59±4.33 years, and 90 (49.5%) of the patients were males. The AIMS65 was superior to the GBS (area under the receiver operating characteristic curve [AUROC] 0.877 vs. 0.695, respectively) and CCI (AUROC 0.877 vs. 0.526, respectively) in predicting the 30-day mortality. All three scores performed poorly in predicting the LOS in hospital. The cutoff threshold that maximized sensitivity and specificity for mortality was three for the AIMS65 score (sensitivity, 0.87; specificity, 0.80; negative predictive values [NPV], 0.977; positive predictive values [PPV], 0.392), 14 for GBS (sensitivity, 0.83; specificity, 0.51; NPV, 0.923; PPV, 0.367), and 5 for CCI (sensitivity, 0.91; specificity, 0.22; NPV, 0.946; PPV, 0.145).

CONCLUSION

The AIMS65 is a simple, accurate, and non-endoscopic scoring system that can be performed easily in ED settings. It is superior to GBS and CCI in predicting 30-day mortality in elderly patients with UGIB.

Utility of Endoscopy in Hospitalized Patients with Gastrointestinal Hemorrhage and Pulmonary Hypertension

BACKGROUND

Gastrointestinal hemorrhage (GIH) has been reported as one of the most common GI complications in patients with pulmonary hypertension (PH). There is paucity of data on the national burden of GIH in patients with PH. We aimed to assess the prevalence, trends and outcomes of endoscopic interventions in patients with PH who were admitted with GIH.

METHOD

We queried National Inpatient Sample (NIS) database from 2005 to 2014 and identified the patients hospitalized with primary or secondary discharge diagnosis of PH (ICD 9 CM Code: 416.0, 416.8, and 416.9). Using Clinical Classification Software Coding system (153) patients with concurrent diagnosis of GIH were then identified. We studied the prevalence and trends of GIH in PH, factors associated with GIH, use of endoscopy, factors associated with utilization of endoscopic interventions, endoscopy outcomes including mortality, and overall healthcare burden.

RESULTS

Out of 7,586,973 PH hospitalizations 3.2% (N = 246,358) had concurrent GIH, with a rising prevalence of GIH in PH patients during the last decade. Clinical predictors for GIH in PH included older age, congestive heart failure, anticoagulation therapy and concurrent alcohol abuse. Mean length of stay (LOS) in PH patients hospitalized with GIH was significantly higher than without GIH (8.6 vs. 6.4 days, p < 0.01) along with a significant increase in hospitalization cost ($20,189 vs. $14,807, p < 0.01). Similarly, odds of in-hospital mortality increase by ~ 1.5 times in PH patients with GIH than those without it (adjusted odds ratio [aOR: 1.45, 95%CI: 1.43-1.47]). Endoscopic interventions were performed in 48.6% of patients with PH and GIH during their hospitalization. Older patients were more likely to undergo endoscopy, as well as the patients who received blood transfusion, and those with hypovolemic shock. Patients with acute respiratory failure and acute renal failure were less likely to get endoscopy. Mean LOS in patients undergoing endoscopic intervention was significantly higher than those who did not receive any intervention (8.7 vs. 8.4 days, p < 0.01), without a substantial increase in hospitalization cost ($20,344 vs. $20,041, p < 0.01). Also, there was a significant decrease in in-hospital mortality in patients undergoing endoscopic interventions.

CONCLUSION

Concurrent GIH in patients with PH increases length of stay; healthcare costs and increases in-hospital mortality. Use of endoscopic interventions in these patients is associated with reduced length of stay, in-hospital mortality without significantly increasing the overall health care burden and should be considered in hospitalized patients with PH who are admitted with GIH. Future studies comparing GIH patients with and without PH should be done to assess if PH is a risk factor for worse outcomes.

Optimal timing of endoscopy for acute upper gastrointestinal bleeding: a systematic review and meta-analysis

Acute upper gastrointestinal bleeding (UGIB) is the most common indication for urgent endoscopy, but the correct timing of endoscopy in these patients is still debated. Our systematic review with meta-analysis was aimed at investigating the potential clinical benefit of very early endoscopy for UGIB patients. We performed an electronic literature search of PubMed, Scopus, Web of Science and the Cochrane Library up to 23rd May 2020 and considered only randomised controlled trials (RCTs) comparing management of UGIB patients by very early vs early endoscopy. Only five RCTs were considered eligible for quantitative analysis, with a total population of 926 cases (468 in the very early endoscopy arm and 458 in the early). The meta-analysis showed no statistically significant benefit for very early endoscopy compared to early endoscopy in terms of risk of rebleeding, mortality, ICU admission, blood transfusion, surgery and length of hospital stay. However, our results showed a significantly higher need for haemostatic treatment when very early endoscopy was performed (RR 1.23, 95% CI 1.06-1.42, p < 0.01) in comparison to early endoscopy.

Clinical algorithms for the prevention of variceal bleeding and rebleeding in patients with liver cirrhosis

Portal hypertension (PH), a common complication of liver cirrhosis, results in development of esophageal varices. When esophageal varices rupture, they cause significant upper gastrointestinal bleeding with mortality rates up to 20% despite state-of-the-art treatment. Thus, prophylactic measures are of utmost importance to improve outcomes of patients with PH. Several high-quality studies have demonstrated that non-selective beta blockers (NSBBs) or endoscopic band ligation (EBL) are effective for primary prophylaxis of variceal bleeding. In secondary prophylaxis, a combination of NSBB + EBL should be routinely used. Once esophageal varices develop and variceal bleeding occurs, standardized treatment algorithms should be followed to minimize bleeding-associated mortality. Special attention should be paid to avoidance of overtransfusion, early initiation of vasoconstrictive therapy, prophylactic antibiotics and early endoscopic therapy. Pre-emptive transjugular intrahepatic portosystemic shunt should be used in all Child C10-C13 patients experiencing variceal bleeding, and potentially in Child B patients with active bleeding at endoscopy. The use of carvedilol, safety of NSBBs in advanced cirrhosis (i.e. with refractory ascites) and assessment of hepatic venous pressure gradient response to NSBB is discussed. In the present review, we give an overview on the rationale behind the latest guidelines and summarize key papers that have led to significant advances in the field.

Management of Patient with Simultaneous Overt Gastrointestinal Bleeding and Myocardial Infarction with ST-Segment Elevation - Priority Endoscopy

Background

The current ERC guidelines are the source of many positive changes, reduction of mortality, length of hospitalization and improvement of prognosis of STEMI patients. However, there is a small group of patients whose slight modification in guidelines would further reduce in-hospital mortality and hospitalization costs. These are patients with concomitant STEMI infarction and gastrointestinal bleeding.

Methods

Two separate methods of treatment were compared in patients with concomitant gastrointestinal bleeding and ST-segment elevation myocardial infarction. The first – traditional approach, in the line with the ESC guidelines, the second innovative, with priority for endoscopy.

Results

Despite the innovative approach, the patient with endoscopy before PCI was discharged without complication. A patient who has undergone coronary intervention and who has been started on typical antiplatelet therapy prior to gastroenterological diagnosis has died due to massive bleeding.

Conclusion

For ethical reasons and in connection with the cardiological guidelines of the management of ACS, a study of patients with ASC a high risk of intestinal bleeding, in which endoscopy will have priority, and only later PCI, will probably never be performed. Although, as the described case shows, despite exceeding the 90 minutes time to implement PCI (<120 minutes) in logistic terms such behavior is completely feasible.

Comparison of the quick SOFA score with Glasgow-Blatchford and Rockall scores in predicting severity in patients with upper gastrointestinal bleeding

INTRODUCTION

Upper gastrointestinal bleeding is one of the common causes of mortality and morbidity. The Rockall score (RS) and Glasgow-Blatchford score (GBS) are frequently used in determining the prognosis and predicting in-hospital adverse events, such as mortality, re-bleeding, hospital stay, and blood transfusion requirements. The quick Sepsis Related Organ Failure Assessment (qSOFA) score is easy and swift to calculate. The commonly used scores and the qSOFA score were compared and why and when these scores are most useful was investigated.

METHOD

133 patients admitted to the emergency department with upper gastrointestinal bleeding over the period of a year, were evaluated in this retrospective study. The RS, GBS and qSOFA score were calculated for each patient, and their relationship with in-hospital adverse events, such as length of hospitalization, rebleeding, endoscopic treatment, blood transfusion requirements, and mortality, was investigated.

RESULTS

The mean overall GBS was 9.72 ± 3.72 (0-19), while that of patients who did not survive was 14.0 ± 1.1 (13-16), with an area under the curve (AUC) of 0.901, a cutoff value of 12.5, and specificity (Spe) and sensitivity (Sen) of 1 and 0.82, respectively. The median value of the GBS, in terms of transfusion need, was 7.12 ± 4.01 (0-15). (AUC = 0.752, cut-off = 9.5, Spe = 0.79, Sen = 0.69). The median value of the qSOFA score, in terms of intensive care need, was 1.73 ± 0.7 (0-3) (AUC = 0.921, cut-off = 0.5, Spe = 0.93, Sen = 0.79). The RS median, in terms of re-bleeding, was 8.22 ± 0.97 (6-9).

CONCLUSION

Early use of risk stratification scores in upper gastrointestinal bleeding is important due to the high risk of morbidity and mortality. All scoring systems were effective in predicting mortality, the need for intensive care, and re-bleeding. The GBS had a greater predictive power in terms of mortality and transfusion need, the qSOFA score for intensive care need, and the RS for re-bleeding. The simpler, more efficient, and more easily calculated qSOFA score can be used to estimate the severity of patients with upper gastrointestinal bleeding.

A novel concept on volumetric assessment and quantification of gastrointestinal bleed on computed tomography angiography: Observations based on a case series

Department of Radiology, Mazumdar Shaw Medical Centre - Narayana Multispecialty Hospital, Narayana Health, Estimation of quantity and rate of bleeding is of great value in the management of patients with acute GI bleed. Endoscopy and multiphase contrast enhanced computed tomography (MCECT) are the presently employed two important methods for this purpose. Still there is a lacuna in the methods of precise estimation of amount of bleed, which at the moment are somewhat unreliable and subjectively evaluated. We present the value of dynamic contrast-enhanced CT examination in quantitatively estimating the amount of extravasated blood with the help of three illustrative clinical examples. Technique CT examination, the methodology for assessment of quantity of bleed is presented and the discussion of existing literature regarding the estimation methods is presented.Bommasandra, Bengaluru, India

The Clinical Impact of Rockall and Glasgow-Blatchford Scores in Nonvariceal Upper Gastrointestinal Bleeding

Introduction

Risk stratification in patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) is crucial for proper management. Rockall score (RS; pre-endoscopic and complete) and Glasgow-Blatchford score (GBS) are some of the most used scoring systems. This study aims to analyze these scores' ability to predict various clinical outcomes and possible cutoff points to identify low- and high-risk patients. Secondarily, this study intents to evaluate the appropriateness of patients' transfers to our facility, which provides a specialized emergency endoscopy service.

Methods

This study was retrospectively conducted at Centro Hospitalar Universitário do Porto and included patients admitted to the Emergency Department with acute manifestations of NVUGIB between January 2016 and December 2018. Receiver operating characteristic (ROC) curves and corresponding areas under the curve (AUC) were calculated. Transferred patients from other institutions and nontransferred (directly admitted to this institution) patients were also compared.

Results

Of a total of 420 patients, 23 (5.9%) died, 34 (8.4%) rebled, 217 (51.7%) received blood transfusion, 153 (36.3%) received endoscopic therapy, 22 (5.7%) had surgery, and 171 (42.3%) required hospitalization in the Intermediate or Intensive Care Unit. Regarding mortality prediction, both complete RS (AUC 0.756, p < 0.001) and pre-endoscopic RS (AUC 0.711, p = 0.001) showed good performance. In the prediction of rebleeding, only complete RS (AUC 0.735, p < 0.001) had discriminative ability. GBS had good performance in the prediction of transfusion (AUC 0.785, p < 0.001). No score showed discriminative capability in the prediction of other outcomes. Transferred and nontransferred patients had similar pre-endoscopic RS (3.41 vs. 3.34, p = 0.692) and GBS (13.29 vs. 12.29, p = 0.056). Only patients with GBS ≥6 were transferred to our facility. There were no adverse outcomes recorded in any group when GBS was ≤3.

Discussion/Conclusion

Complete RS and pre-endoscopic RS are effective at predicting mortality, but only complete RS showed good performance at predicting rebleeding. GBS is better at predicting transfusion requirement. Our study suggests that a transfer can possibly be reconsidered if GBS is ≤3, although current recommendations only propose outpatient care when GBS is 0 or 1. Patients' transfers were appropriate, considering the high GBS scores and the outcomes of these patients.

Hemostatic spray powder TC-325 in the primary endoscopic treatment of peptic ulcer-related bleeding: multicenter international registry

BACKGROUND

Upper gastrointestinal bleeding (UGIB) is a leading cause of morbidity and is associated with a 2 % - 17 % mortality rate in the UK and USA. Bleeding peptic ulcers account for 50 % of UGIB cases. Endoscopic intervention in a timely manner can improve outcomes. Hemostatic spray is an endoscopic hemostatic powder for GI bleeding. This multicenter registry was created to collect data prospectively on the immediate endoscopic hemostasis of GI bleeding in patients with peptic ulcer disease when hemostatic spray is applied as endoscopic monotherapy, dual therapy, or rescue therapy.

METHODS

Data were collected prospectively (January 2016 - March 2019) from 14 centers in the UK, France, Germany, and the USA. The application of hemostatic spray was decided upon at the endoscopist's discretion.

RESULTS

202 patients with UGIB secondary to peptic ulcers were recruited. Immediate hemostasis was achieved in 178/202 patients (88 %), 26/154 (17 %) experienced rebleeding, 21/175 (12 %) died within 7 days, and 38/175 (22 %) died within 30 days (all-cause mortality). Combination therapy of hemostatic spray with other endoscopic modalities had an associated lower 30-day mortality (16 %, P < 0.05) compared with monotherapy or rescue therapy. There were high immediate hemostasis rates across all peptic ulcer disease Forrest classifications.

CONCLUSIONS

This is the largest case series of outcomes of peptic ulcer bleeding treated with hemostatic spray, with high immediate hemostasis rates for bleeding peptic ulcers.

Perfusion index: Could this be a new triage tool for upper gastrointestinal system bleeding in the emergency department? A prospective cohort study

BACKGROUND

Many scoring systems for predicting mortality, rebleeding and transfusion needs among patients with upper gastrointestinal bleeding (UGIB) have been developed. However, no scoring system can predict all these outcomes.

OBJECTIVE

To show whether the perfusion index (PI), compared with the Rockall score (RS), helps predict transfusion needs and prognoses among patients presenting with UGIB in emergency departments. In this way, critical patients with transfusion needs can be identified at an early stage.

DESIGN AND SETTING

Prospective cohort study in an emergency department in Turkey, conducted between June 2018 and June 2019.

METHODS

Patients' demographic parameters, PI, RS, transfusion needs and prognosis were recorded.

RESULTS

A total of 219 patients were included. Blood transfusion was performed in 174 patients (79.4%). The PI cutoff value for prediction of the need for blood transfusion was 1.17, and the RS cutoff value was 5. The area under the curve (AUC) value for PI (AUC: 0.772; 95% confidence interval, CI: 0.705-0.838; P < 0.001) was higher than for RS (AUC: 0.648; 95% CI: 0.554-0.741; P = 0.002). 185 patients (84.5%) were discharged, and 34 patients (15.5%) died. The PI cutoff value for predicting mortality was 1.1, and the RS cutoff value was 7. The AUC value for PI (AUC: 0.743; 95% CI: 0.649-0.837; P < 0.001) was higher than for RS (AUC: 0.725; 95% CI: 0.639-0.811; P < 0.001).

CONCLUSION

PI values for patients admitted to emergency departments with UGIB on admission can help predict their need for transfusion and mortality risk.

Risk Factor Analysis And Method Development For Predicting The Recurrence Of Gastroduodenal Ulcer Bleeding

Objective — To clarify clinical, laboratory and endoscopic signs of a high recurrence risk of gastroduodenal ulcer bleeding (GDUB) and to develop a multifactorial method for its prediction. Material and Methods — The research was completed over 2019-2020. The study took place in two stages. At the first stage, 409 patients with GDUB, who were treated at the emergency surgical department of Saratov City Clinical Hospital No. 6 from 1991 to 2000, were included in the study. During that time, endoscopic hemostasis therapy was used in a few cases, while modern antisecretory therapy has not yet been developed and carried out. Two groups of patients were compared: with recurrent bleeding (104 patients) and without recurrent bleeding (305 patients). At the second stage, a retrospective analysis of the outcomes of treating 126 patients with GDUB, cared for at the clinic from 2001 to 2009, was carried out. During this period of time, assistance for this pathology was the most complete and matched all current standards. The analysis included 63 patients with recurrent bleeding and 63 patients without recurrent bleeding. We conducted a comparative analysis of the developed method for predicting bleeding recurrence versus the classifications by J.A. Forrest (1974) and G.P. Giderim (1992) in our original modification. Results — At the first stage of the study, the most significant signs for predicting recurrent bleeding were identified as unstable hemodynamics, severity of blood loss, nature of vomiting, presence of concomitant pathology, state of the ulcer surface sensu J.A. Forrest; and localization, size and depth of the ulcer. We determined their informative value in assessing the risk of recurrent bleeding and developed a novel method of its prediction. Taken alone, each of nine predictive signs has a correlation, comparable in the magnitude with patient allocation into each group (based on the absolute value of gamma, ranging 0.49–0.66); the prediction accuracy is 60–74%, with a positive predictive value of 35-49%. The measure of the gamma relationship for splitting patients among groups by the original method based on nine features in conjunction with each other was -0.79 (p<0.001). Conclusion — Prediction of recurrent bleeding by one or two signs is inferior in informational content (although insignificantly) to the multifactorial method. The developed method for predicting the recurrence of ulcer bleeding from nine signs has an optimal ratio of sensitivity and specificity, which ensures a prediction accuracy of over 70% and a positive predictive value of 68.9%.

Comparison of various risk scores for the prognosis of hemorrhagic upper gastrointestinal mucosal disorder

Background

Various risk scores have been proposed that are useful for the management of upper gastrointestinal bleeding (UGIB), which is an important disease in emergency medicine. Few studies have examined the usefulness of Charlson Comorbidity index (CCI) in this disease, which evaluates the patient’s general condition by scoring the patient’s underlying disease. There have been no studies investigating the efficacy of CCI compared to other risk scores in the management of UGIB requiring endoscopic hemostasis.

Methods

In addition to the Glasgow-Blatchford score, AIMS65 score, and Rockall score, we investigated the efficacy of the outcome prediction obtained by the original CCI and the updated CCI, scored only with respect to the underlying disease. We also examined the cutoff value when using the risk score. This retrospective study included 265 patients with hemorrhagic upper gastrointestinal mucosal lesions who underwent emergency endoscopic hemostasis during a 6-year period between 2011 and 2016 in our hospital.

Results

The updated CCI and AIMS65 score correlated with prognosis in multivariate analysis (p = 0.002 and p = 0.003, respectively). In clinical practice, the prognosis might be worse if both updated CCI and AIMS65 score were 3 point or more.

Conclusion

In addition to the AIMS65 score, the updated CCI can be a useful tool for managing upper gastrointestinal mucosal disorder bleeding that requires endoscopic hemostasis.

Immature Granulocyte Count and Percentage as New Predictors of Mortality in Patients with Upper Gastrointestinal Bleeding

Aims

Early identification of patients at risk of adverse outcomes may increase the survival rates in patients with upper gastrointestinal bleeding (UGIB), but this can be difficult to predict in emergencies. The aim of the study is to evaluate immature granulocyte (IG), which can be obtained from simple hemogram tests in patients with UGIB, in terms of clinical use and as a mortality marker.

Materials and methods

The patients diagnosed with UGIB between March 1, 2019, and September 30, 2019, were evaluated retrospectively. Demographic characteristics, causes of hemorrhage, clinical presentations, hemogram, and biochemistry values at ED admission and 30-day mortality status of the patients were examined. We divided the patients into groups according to their mortality status, and the groups were compared among themselves in terms of parameters.

Results

A total of 213 patients who met the inclusion criteria were included in the study. Of these patients, 139 (65.3%) were male and the mean age was 65.05 ± 16.7 years. Fifteen (7%) of them were in the nonsurvival group, while 198 (93%) were in the survival group. The efficacy of both the IG count (IGC) and IG% in predicting mortality was statistically significant (p = 0.002, p = 0.008, respectively). The sensitivity and specificity for the IGC were found as 60% and 84.4; for the IG%, they were found as 66.7% and 75.7%, respectively.

Conclusion

IGC and IG% are independent risk factors for the 30-day mortality status. These measurements are obtained from simple hemogram tests and may be useful for the evaluation of mortality in patients with UGIB.

Semiautomated Glasgow-Blatchford Bleeding Score helps direct bed placement for patients with upper gastrointestinal bleeding

OBJECTIVE

The Glasgow-Blatchford Bleeding Score (GBS) was designed to identify patients with upper gastrointestinal bleeding (UGIB) who do not require hospitalisation. It may also help stratify patients unlikely to benefit from intensive care.

DESIGN

We reviewed patients assigned a GBS in the emergency room (ER) via a semiautomated calculator. Patients with a score ≤7 (low risk) were directed to an unmonitored bed (UMB), while those with a score of ≥8 (high risk) were considered for MB placement. Conformity with guidelines and subsequent transfers to MB were reviewed, along with transfusion requirement, rebleeding, length of stay, need for intervention and death.

RESULTS

Over 34 months, 1037 patients received a GBS in the ER. 745 had an UGIB. 235 (32%) of these patients had a GBS ≤7. 29 (12%) low-risk patients were admitted to MBs. Four low-risk patients admitted to UMB required transfer to MB within the first 48 hours. Low-risk patients admitted to UMBs were no more likely to die, rebleed, need transfusion or require more endoscopic, radiographic or surgical procedures than those admitted to MBs. No low-risk patient died from GIB. Patients with GBS ≥8 were more likely to rebleed, require transfusion and interventions to control bleeding but not to die.

CONCLUSION

A semiautomated GBS calculator can be incorporated into an ER workflow. Patients with a GBS ≤7 are unlikely to need MB care for UGIB. Further studies are warranted to determine an ideal scoring system for MB admission.

The Prognosis Analysis of Liver Cirrhosis with Acute Variceal Bleeding and Validation of Current Prognostic Models: A Large Scale Retrospective Cohort Study

Background

Acute variceal bleeding is a major cause of death in liver cirrhosis. This large scale retrospective cohort study aims to analyze the prognosis of patients with cirrhosis and acute variceal bleeding and to validate the current prognostic models.

Methods

Patients with cirrhosis and acute variceal bleeding were enrolled from Jan 2019 to March 2020. The independent prognostic factors for in-hospital death were identified by logistic regression analyses. Area under curves (AUCs) was compared among Child-Pugh, cirrhosis acute gastrointestinal bleeding (CAGIB) score, and model for end-stage liver disease (MELD) and neutrophil-lymphocyte ratio (NLR) scores.

Results

Overall, 379 patients with liver cirrhosis and acute variceal bleeding were consecutively evaluated. The majority of the patients were males (59.1%) and the mean age of all patients were 53.7 ± 1.3 years (range 14-89). Hepatitis B virus (HBV) was the most common underlying cause of liver cirrhosis (54.1%). 72 (19%) patients had hepatocellular carcinoma. Multivariate logistic regression analyses showed that age, HCC, WBC, total serum bilirubin, serum creatinine, and ALT were independently associated with in-hospital death. And the odds ratios (ORs) for in-hospital death were 1.066 (95% CI 1.017-1.118, P = 0.008), 7.19 (95% CI 2.077-24.893, P = 0.001), 1.123 (95% CI 1.051-1.201, P = 0.001), 1.014 (95% CI 1.005-1.023, P = 0.003), 1.012 (95% CI 1.004-1.021, P = 0.006), and 1.005 (95% CI 1.000-1.009, P = 0.036), respectively. In the whole cohort with HCC patients, the AUCs of Child-Pugh, CAGIB, MELD and NLR scores were 0.842 (95% CI 0.801-0.878), 0.840 (95% CI 0.799-0.876), 0.798 (95% CI 0.754-0.838), and 0.688 (95% CI 0.639-0.735), respectively. The differences were statistically significant between Child-Pugh and NLR scores (P = 0.0118), and between CAGIB and NLR scores (P = 0.0354).

Conclusion

Child-Pugh and CAGIB scores showed better predictive performance for prognosis of patients with cirrhosis and acute variceal bleeding than NLR scores.

Gastrointestinal Stromal Tumor: GIST Another Duodenal Ulcer

Background: Gastrointestinal stromal tumors (GISTs), although exceedingly rare, are the most common mesenchymal tumors in the gastrointestinal (GI) tract. GISTs are often asymptomatic; approximately 10% are found incidentally on imaging or endoscopy for other indications, although GI bleeding, intestinal obstruction, and perforation can occur. We present a case of upper GI bleeding from a duodenal GIST. Proton-pump inhibitor (PPI) therapy resulted in complete endoscopic ulcer healing, yet a discrete mass lesion was identified on endoscopic ultrasound (EUS). Case Report: A 70-year-old female presented with upper GI bleeding, and a duodenal ulcer was identified with esophagogastroduodenoscopy (EGD). Computed tomography (CT) scan of the abdomen and pelvis showed duodenal bulb thickening without clear mass. The ulcer was treated with 1:10,000 concentration epinephrine, injected in 4 quadrants around the ulcer base. The patient's GI bleeding resolved, and she was discharged with a referral for outpatient EUS follow-up. One month later, EUS showed resolution of the ulcer after PPI therapy but also showed a lesion consistent with GIST that was confirmed by cytologic analysis. The patient was started on imatinib therapy and had no further bleeding. Conclusion: Initial EGD and CT findings could have easily been attributed to duodenal peptic ulcer disease for which follow-up endoscopy is not routinely recommended given the low risk of malignancy. However, because of the high index of suspicion on the part of the referring physicians, duodenal GIST was diagnosed. This case extends the spectrum of the presentation, evaluation, and diagnosis of GISTs and stresses the importance of keeping this rare disease on the provider's differential, even after routine workup shows no findings of tumor.

Prognostic value of risk scoring systems for cirrhotic patients with variceal bleeding

BACKGROUND

Acute variceal bleeding is one of the deadliest complications of cirrhosis, with a high risk of in-hospital rebleeding and mortality. Some risk scoring systems to predict clinical outcomes in patients with upper gastrointestinal bleeding have been developed. However, for cirrhotic patients with variceal bleeding, data regarding the predictive value of these prognostic scores in predicting in-hospital outcomes are limited and controversial.

AIM

To validate and compare the overall performance of selected prognostic scoring systems for predicting in-hospital outcomes in cirrhotic patients with variceal bleeding.

METHODS

From March 2017 to June 2019, cirrhotic patients with acute variceal bleeding were retrospectively enrolled at the Second Affiliated Hospital of Xi’an Jiaotong University. The clinical Rockall score (CRS), AIMS65 score (AIMS65), Glasgow-Blatchford score (GBS), modified GBS (mGBS), Canada-United Kingdom-Australia score (CANUKA), Child-Turcotte-Pugh score (CTP), model for end-stage liver disease (MELD) and MELD-Na were calculated. The overall performance of these prognostic scoring systems was evaluated.

RESULTS

A total of 330 cirrhotic patients with variceal bleeding were enrolled; the rates of in-hospital rebleeding and mortality were 20.3% and 10.6%, respectively. For in-hospital rebleeding, the discriminative ability of the CTP and CRS were clinically acceptable, with area under the receiver operating characteristic curves (AUROCs) of 0.717 (0.648-0.787) and 0.716 (0.638-0.793), respectively. The other tested scoring systems had poor discriminative ability (AUROCs < 0.7). For in-hospital mortality, the CRS, CTP, AIMS65, MELD-Na and MELD showed excellent discriminative ability (AUROCs > 0.8). The AUROCs of the mGBS, CANUKA and GBS were relatively small, but clinically acceptable (AUROCs > 0.7). Furthermore, the calibration of all scoring systems was good for either in-hospital rebleeding or death.

CONCLUSION

For cirrhotic patients with variceal bleeding, in-hospital rebleeding and mortality rates remain high. The CTP and CRS can be used clinically to predict in-hospital rebleeding. The performances of the CRS, CTP, AIMS65, MELD-Na and MELD are excellent at predicting in-hospital mortality.

Comparison of various prognostic scores in variceal and non-variceal upper gastrointestinal bleeding: A prospective cohort study

BACKGROUND AND AIMS

Various prognostic scores like Glasgow-Blatchford bleeding score (GBS), modified Glasgow-Blatchford bleeding score (mGBS), full Rockall score (FRS) including endoscopic findings, clinical Rockall score (CRS), and albumin, international normalized ratio (INR), mental status, systolic blood pressure, age >65 (AIMS65) are used for risk stratification in patients with upper gastrointestinal bleeding (UGIB). The utility of these scores in variceal UGIB (VUGIB) is not well defined. In this prospective study, we aimed to assess the performance of these scores in patients with non-variceal (NVUGIB) and VUGIB.

METHODS

We included 1011 patients (during March 2017 and August 2018) including 439 with NVUGIB and 572 VUGIB. Performance of GBS, mGBS, FRS, CRS, and AIMS65 for various outcome measures was analyzed using the area under receiver operator characteristic curve (AUROC).

RESULTS

The accuracy of prognostic scores in predicting the composite outcome including the need of hospital-based intervention and 42-day mortality was higher in NVUGIB as compared with VUGIB, AUROC: CRS: 0.641 vs. 0.537; FRS: 0.669 vs. 0.625; GBS: 0.719 vs. 0.587; mGBS: 0.711 vs. 0.594; AIMS65: 0.567 vs. 0.548. GBS and mGBS at a cut-off score of 1 had the highest negative predictive value, 91.7% and 91.3%, respectively, for predicting composite outcome in NVUGIB. Similarly, these scores had better accuracy for predicting 42-day rebleeding in NVUGIB as compared to VUGIB, AUROC: CRS: 0.680 vs. 0.537; FRS: 0.698 vs. 0.565; GBS: 0.661 vs. 0.543; mGBS: 0.627 vs. 0.540; AIMS65: 0.695 vs. 0.606.

CONCLUSION

The prognostic scores such as CRS, FRS, GBS, mGBS, and AIMS65 predict the need for hospital-based management, rebleeding, and mortality better among patients with NVUGIB than VUGIB.

Both Full Glasgow-Blatchford Score and Modified Glasgow-Blatchford Score Predict the Need for Intervention and Mortality in Patients with Acute Lower Gastrointestinal Bleeding

BACKGROUND

Glasgow-Blatchford score (GBS) has been developed for risk stratification in management of acute upper gastrointestinal (GI) bleeding. However, the performance of GBS in patients with lower GI bleeding is unknown.

AIM

To evaluate the performance of full or modified GBS and modified GBS in prediction of major clinical outcomes in patients with lower GI bleeding.

METHODS

A retrospective study of patients admitted to a tertiary care center with either non-variceal upper GI bleeding or lower GI bleeding was conducted. The full and modified GBS were calculated for all patients. The primary outcome was a combined outcome of inpatient mortality, need for endoscopic, surgical, or radiologic procedure to control the bleed or treat the underlying source, and need for blood transfusion.

RESULTS

A total of 1026 patients (562 cases for upper GI and 464 cases for lower GI) were included in the study. Hospital-based interventions and mortality were significantly higher in upper GI bleeding group. The performance of the full GBS in lower GI bleeding (area under the receiver operating curve (AUROC) 0.78, 95% CI 0.74-0.82) was comparable to full GBS in upper GI bleeding (AUROC 0.77, 95% CI 0.73-0.81) in predicting the primary outcome. Similarly, the performance of modified GBS in lower GI bleeding was shown to be comparable to modified GBS in upper GI bleeding (AUROC 0.78, 95% CI 0.74-0.83 vs. AUROC 0.76 95% CI 0.72-0.80).

CONCLUSION

In patients with lower GI bleeding, both full GBS and modified GBS can predict the need for hospital-based interventions and mortality.

Evaluation of scoring systems without endoscopic findings for predicting outcomes in patients with upper gastrointestinal bleeding

Background

Risk scoring systems are used to evaluate patients with upper gastrointestinal bleeding (UGIB). We compared Glasgow-Blatchford score (GBS), modified GBS (mGBS), and Pre-endoscopy Rockall score (Pre-E RS) for immediate application without endoscopic findings in predicting the need of interventions and the 30-day mortality in patients with UGIB.

Methods

Patients who visited the emergency room with UGIB from January 2007 to June 2016 were included. GBS, mGBS, and Pre-E RS were obtained for all patients. The area under the receiver-operating characteristic curves (AUC) was used to assess the accuracy of the scoring systems to determine the need for interventions and 30-day mortality. Also, we investigated the potential cutoff scores for predicting 30-day mortality and the need for interventions.

Results

In predicting the need for interventions, GBS (AUC = 0.727) and mGBS (AUC = 0.733) outperformed Pre-E RS (AUC = 0.564, P < 0.0001). In predicting 30-day mortality, Pre-E RS (AUC = 0.929) outperformed GBS (AUC = 0.664, P < 0.0001) and mGBS (AUC = 0.652, P < 0.0001). Based on AUC analyses of sensitivities and specificities, the optimal cutoff mGBS and GBS for the need for interventions was 9 (70.71% sensitivity, 89.35% specificity) and 9 (73.57% sensitivity, 82.90% specificity) respectively, and optimal cutoff Pre-E RS for 30-day mortality was 4 (88.0% sensitivity, 97.52% specificity).

Conclusions

GBS and mGBS are considered to be moderately accurate in making an early decision about the need of interventions in patients with UGIB. Pre-E RS is considered to be highly accurate in early detection of patients at high risk for 30-day mortality without endoscopic findings. In addition, we suggested potential cutoff scores to predict the need of interventions for GBS and mGBS, and 30-day mortality for Pre-E RS. Further studies are needed to confirm the clinical applicability of results.

Multicenter evaluation of first-line endoscopic treatment with the OTSC in acute non-variceal upper gastrointestinal bleeding and comparison with the Rockall cohort: the FLETRock study

INTRODUCTION

The over-the-scope clip (OTSC) overcomes limitations of standard clips and achieves a more efficient and reliable hemostasis in non-variceal upper gastrointestinal bleeding (NVUGIB). The study aims to evaluate mortality, rebleeding, and mortality after rebleeding of patients in whom the OTSC was used as the first-line endoscopic treatment (FLET) of NVUGIB.

PATIENTS AND METHODS

In total, 118 patients (FLET cohort) with a median age of 73.5 years (range 29-93 years; mean (±SD) 71.39 ± 12.39 years) were included. The distribution of patients with respect to risk category revealed a median Rockall score of 7 (range 3-10). For hypothesis testing, the FLET cohort was categorized into three risk groups taking into account the Rockall score: low risk [Rockall risk category (RRC ≤3)], moderate risk (RRC 4-7), and high risk (RRC ≥8). Event rates (mortality, rebleeding, and mortality after rebleeding) observed per risk group were compared to predicted event rates (Rockall cohort) using Fisher's Exact Test.

RESULTS

Primary successful hemostasis (PSH) was achieved in 92.4% either by FLET alone or in combination with an additional hemostasis technique in 1.7% (SCS = secondary clinical success). In 7.5% of the FLET cohort PSH could not be achieved. Compared to RRC prediction, mortality after rebleeding was significantly reduced from 27.9 to 10.9% in the high-risk group (RRC ≥8) treated with FLET (p < 0.011). Furthermore, the occurrence of rebleeding or continued bleeding was significantly lower in the moderate risk group (RRC 4-7) with 4.9% as well as in the high-risk group (RRC ≥8) with 21.4% compared to the Rockall cohort 24.0 and 53.2%, respectively (p < 0.001).

CONCLUSIONS

This study shows that OTSC is superior to standard care and FLET reduces significantly rebleeding and rebleeding-associated mortality in NVUGIB. For this reason, OTSC could be the treatment of choice as the first-line treatment as an alternative to standard hemostasis techniques in high-risk patients.

Readmission after Gastrointestinal Bleeding in Children: A Retrospective Cohort Study

INTRODUCTION

To compare the demographic, clinical, and therapeutic characteristics in a cohort of patients discharged following acute gastrointestinal bleeding, representing to the emergency department (ED) and readmitted within 30 days of discharge with the characteristics of non-readmitted patients.

STUDY DESIGN

Hospitalization data was obtained from the Pediatric Hospital Information System including 49 tertiary children's hospitals in the US. Children 1-21 years of age diagnosed with acute gastrointestinal bleeding, admitted between January 2007 and September 2015 were included. The primary outcomes in this study were 30-day inpatient readmission through the ED and 30-day return to the ED only. Unadjusted, univariate followed by multivariable analysis of the associations between patient characteristics and treatment course at the index encounter using the R statistical package, v. 3.2.3.

RESULTS

During the study period, 9902 patients were admitted with acute gastrointestinal bleeding; in the following month, 1460 (16.1%) represented to the ED and 932 (9%) were readmitted; 68.7% within 14 days from discharge. Readmission was most frequently associated with portal hypertension or esophageal variceal hemorrhage. There was a decreased likelihood of readmission with endoscopy (OR 0.77, 95% CI, 0.661, 0.906) and with Meckel scan (OR 0.513, 95% CI 0.362, 0.727) during the initial admission. Multiple comorbidities, longer initial stay and the early proton pump inhibitor therapy were associated with higher likelihood of readmission.

DISCUSSION

Readmission following acute gastrointestinal bleeding is common and is more likely following variceal hemorrhage, long initial admission, and chronic comorbidities.

Comparison of three scoring systems in predicting clinical outcomes in patients with acute upper gastrointestinal bleeding: a prospective observational study

OBJECTIVE

To compare the performances of the Glasgow-Blatchford score (GBS), modified GBS (mGBS) and AIMS65 in predicting clinical outcomes in patients with acute upper gastrointestinal bleeding (AUGIB).

METHODS

This study enrolled 320 consecutive patients with AUGIB. Patients at high and low risks of developing adverse clinical outcomes (rebleeding, the need of clinical intervention and death) were categorized according to the GBS, mGBS and AIMS65 scoring systems. The outcome of the patients were the occurrences of adverse clinical outcomes. The areas under the receiver operating characteristics curve (AUROC) of three scoring systems were compared.

RESULTS

Irrespective of the systems used, the high-risk groups showed higher rates of rebleeding, intervention and death compared with the low-risk groups (P < 0.05). For the prediction of rebleeding, AIMS65 (AUROC 0.735, 95% CI 0.667-0.802) performed significantly better than GBS (AUROC 0.672, 95% CI 0.597-0.747; P < 0.01) and mGBS (AUROC 0.677, 95% CI 0.602-0.753; P < 0.01). For the prediction of interventions, there was no significant difference among the three systems (GBS: AUROC 0.769, 95% CI 0.668-0.870; mGBS: AUROC 0.745, 95% CI 0.643-0.847; AIMS65: AUROC 0.746, 95% CI 0.640-0.851). For the prediction of in-hospital mortality, there was no significant difference among the three systems (GBS: AUROC 0.796, 95% CI 0.694-0.898; mGBS: AUROC 0.803, 95% CI 0.703-0.904; AIMS65: AUROC 0.786, 95% CI 0.670-0.903).

CONCLUSIONS

The three scoring systems are reliable and accurate in predicting the rates of rebleeding, surgery and mortality in AUGIB. However, AIMS65 outperforms GBS and mGBS in predicting rebleeding.

Comparison of Glasgow-Blatchford score and full Rockall score systems to predict clinical outcomes in patients with upper gastrointestinal bleeding

Background

Various risk scoring systems have been recently developed to predict clinical outcomes in patients with upper gastrointestinal bleeding (UGIB). The two commonly used scoring systems include full Rockall score (RS) and the Glasgow-Blatchford score (GBS). Bleeding scores were assessed in terms of prediction of clinical outcomes in patients with UGIB.

Patients and methods

Two hundred patients (age >18 years) with obvious symptoms of UGIB in the emergency department of Rasoul Akram Hospital were enrolled. Full RS and GBS were calculated. We followed the patients for records of rebleeding and 1-month mortality. A receiver operating characteristic curve by using areas under the curve (AUCs) was used to statistically identify the best cutoff point.

Results

Eighteen patients were excluded from the study due to failure to follow-up. Rebleeding and mortality rate were 9.34% (n=17) and 11.53% (n=21), respectively. Regarding 1-month mortality, full RS was better than GBS (AUC, 0.648 versus 0.582; P=0.021). GBS was more accurate in terms of detecting transfusion need (AUC, 0.757 versus 0.528; P=0.001), rebleeding rate (AUC, 0.722 versus 0.520; P=0.002), intensive care unit admission rate (AUC, 0.648 versus 0.582; P=0.021), and endoscopic intervention rate (AUC, 0.771 versus 0.650; P<0.001).

Conclusion

We found the full RS system is better for 1-month mortality prediction while GBS system is better for prediction of other outcomes.
