Usefulness of prognostic indices in upper gastrointestinal bleeding

Child-Pugh Score, MELD Score and Glasgow Blatchford Score to Predict the In-Hospital Outcome of Portal Hypertensive Patients Presenting with Upper Gastrointestinal Bleeding: An Experience from Tertiary Healthcare System

The two most familiar scores used for prognostication of liver cirrhosis are the Model for End-stage Liver Disease (MELD) and Child-Turcotte-Pugh (CTP), while the Glasgow-Blatchford (GB) score is used for sorting non-variceal upper gastrointestinal hemorrhage into high- or low-risk categories. This study evaluates the validity of the CTP, MELD, and GB scoring systems in prognosticating the in-hospital outcome of bleeding portal hypertensive patients. In this study, the ROC curve and Younden index determine the efficacy of three scoring systems. The results indicate that CTP was the most efficient score as the predictor of outcome (AUC = 0.9, cut-off value > 7); followed by MELD (AUC = 0.8, cut-off value > 18) and then the GB score (AUC = 0.64, cut-off value > 14) (p < 0.05). In pair-wise comparison, the difference between CTP and MELD was insignificant (p > 0.05). Patients with a CTP score of >7 had notably higher in-hospital mortality (19.8% vs. 0.9%, p < 0.0001). Similarly, mortality with a MELD score > 18 was significant (14.8% vs. 5.9% (p < 0.0001). The GB score was not a good indicator of the outcome. Platelets, albumin, CTP, and MELD scores were the independent contributors to mortality. Thus, as liver cirrhosis prognosticators, CTP and MELD scores can also both be used as predictive scores of the in-hospital outcomes of bleeding patients due to portal hypertension. Compared to the GB score, CTP and MELD scores are fairly efficient predictors in these patients.

Prediction of in-hospital mortality after acute upper gastrointestinal bleeding: cross-validation of several risk scoring systems

OBJECTIVE

We aimed to identify the clinical, biochemical, and endoscopic features associated with in-hospital mortality after acute upper gastrointestinal bleeding (AUGIB), focusing on cross-validation of the Glasgow-Blatchford score (GBS), full Rockall score (RS), and Cedars-Sinai Medical Center Predictive Index (CSMCPI) scoring systems.

METHODS

Our prospective cross-sectional study included 156 patients with AUGIB. Several statistical approaches were used to assess the predictive accuracy of the scoring systems.

RESULTS

All three scoring systems were able to accurately predict in-hospital mortality (area under the receiver operating characteristic curve [AUC] > 0.9); however, the multiple logistic model separated the presence of hemodynamic instability (state of shock) and the CSMCPI as the only significant predictive risk factors. In compliance with the overall results, the CSMCPI was consistently found to be superior to the other two systems (highest AUC, highest sensitivity and specificity, highest positive and negative predictive values, highest positive likelihood ratio, lowest negative likelihood ratio, and 1-unit increase in CSMCPI associated with 6.3 times higher odds of mortality), outperforming the GBS and full RS.

CONCLUSIONS

We suggest consideration of the CSMCPI as a readily available and reliable tool for accurately predicting in-hospital mortality after AUGIB, thus providing an essential backbone in clinical decision-making.

Timing of Emergency Endoscopy for Acute Upper Gastrointestinal Bleeding: A Literature Review

Upper gastrointestinal (GI) bleeding is a common cause for Emergency Department and hospital admissions and has significant mortality and morbidity if it remains untreated. Upper endoscopy is the key procedure for both diagnosis and treatment of acute upper GI bleeding. The aim of this article is to review the optimal timing of endoscopy in patients with acute upper GI bleeding. The cost-effectiveness and the influence of urgent or emergent endoscopy on patients' outcomes are discussed. Also, we compare and contrast the available evidence and guidelines regarding the recommended time points for performing endoscopy in different clinical settings.

Risk factors associated with clinically significant gastrointestinal bleeding in pediatric ED

INTRODUCTION

Gastrointestinal bleeding is a common problem in pediatric emergency department (PED). Some of these patients can lose significant amount of blood which may lead to shock. The aim of this study is to determine the risk factors predicting clinically significant gastrointestinal (GIS) bleeding in patients presenting to PED.

METHODS

This study was performed prospectively from January 1st 2013 to December 31th 2013 in patients with upper or lower GIS bleeding. Clinically significant GIS bleeding was defined as >2g/dL hemoglobin decrease at any time during observation in PED, need for erythrocyte transfusion or need for rapid endoscopic evaluation.

RESULTS

105 patients were enrolled, 81 of which were eligible for the study. Twenty two patients (26,8%) had clinically significant GIS bleeding. These patients have significantly more commonly have upper GI bleeding and symptoms of melena, pallor and tachycardia. Initial laboratory findings revealed lower hemoglobin, RBC and albumin levels with higher WBC and BUN levels. They need significantly more nasogastric tube placement and PPI and H2 blocker treatment. Final diagnosis included more gastritis and peptic ulcers. These patients have less hematochezia, less lower gastrointestinal bleeding and less commonly diagnosed as acute gastroenteritis or Mallory Weiss tear as a final diagnosis.

CONCLUSIONS

Pediatric emergency physicians should be aware of clinical and laboratory parameters of patients with clinically significant GIS bleeding to predict which patients are under risk of life threatening blood loss. Patients who have melena, pallor, tachycardia, anemia and uremia at presentation are more prone to have significant GIS bleeding.

Comparison of Risk Stratification Scores for Patients Presenting with Symptoms of Upper Gastrointestinal Bleeding in the Emergency Department

Objective

To compare four scoring systems to predict outcomes in patients with symptoms of upper gastrointestinal bleeding presenting to the emergency department.

Method

A single centered prospective cohort study. All adult patients presenting to the emergency department of the studying centre with haematemsis or tarry stool or coffee ground vomiting or coffee ground aspirate from nasogastric tube were included from February 2012 to April 2012. The outcome variables include mortality, length of stay in hospital, blood product transfusion and interventions for bleeding control. The AIMS65 score, pre-endoscopic Rockall score, Glasgow Blatchford Score (GBS) and the modified Glasgow Blatchford Score (mGBS) were evaluated. Diagnostic characteristics were presented and areas under the receiver-operating-characteristic (AUROC) curve were compared.

Results

A total of 129 patients were included in the study. 81 of them (62.8%) had upper endoscopy performed. The mortality rate was 3.1%. Initial haemoglobin level of <10 was an important factor in risk stratification. Validation of the 4 scoring systems showed GBS had highest sensitivities (98.3-100%) and negative predictive values (90-100%) for all outcome variables but could not achieve a good specificity and positive predictive values against the outcomes. Both GBS and modified GBS outperformed the other two scoring systems in the AUROC curves in predicting composite high-risk outcome, length of stay in hospital and blood transfusion.

Conclusion

GBS appeared the best scoring system in the emergency department for screening purpose and to stratify those high risk patients for admission and low risk patients for out-patient management. (Hong Kong j.emerg.med. 2016;23:199-209)

Prospective multicenter validation of the Glasgow Blatchford bleeding score in the management of patients with upper gastrointestinal hemorrhage presenting at an emergency department

BACKGROUND/AIMS

The Glasgow Blatchford Bleeding Score (GBS) has been developed to assess the need for treatment in patients with acute upper gastrointestinal hemorrhage (UGIH) presenting at emergency departments (EDs). We aimed (a) to determine the validity of the GBS and Rockall scoring systems for prediction of need for treatment and (b) to identify the optimal cut-off value of the GBS.

METHODS

We carried out a population-based, prospective multicenter study of 520 consecutive patients presenting with acute UGIH at EDs of three hospitals. The accuracy of GBS and Rockall scores in predicting the need for treatment (i.e. endoscopic, surgical, or radiological intervention and blood transfusion) was analyzed using receiver operating characteristic curves.

RESULTS

Receiver operating characteristic curve analysis showed that the GBS had a good discriminative ability to determine the need for treatment in patients with acute UGIH (area under the curve: 0.88; 95% confidence interval: 0.85-0.91). The GBS was superior to both the clinical Rockall and the full Rockall score in predicting the need for treatment (area under the curve: 0.86 vs. 0.70 vs. 0.77). At a cut-off value of up to 2, the GBS had the optimal combination of sensitivity (99.4%) and specificity (42.4%).

CONCLUSION

The GBS is superior compared with both Rockall scores in predicting the need for treatment in patients with suspected acute UGIH presenting at EDs in the Netherlands. Patients with a GBS of 2 or less form a subgroup of low-risk patients. These low-risk patients are eligible for outpatient management, which might reduce hospital admissions and healthcare costs.

[Validation of the Glasgow-Blatchford Scoring System to predict mortality in patients with upper gastrointestinal bleeding in a hospital of Lima, Peru (June 2012-December 2013)]

BACKGROUND AND AIM

Upper gastrointestinal bleeding is a major cause of hospitalization and the most prevalent emergency worldwide, with a mortality rate of up to 14%. In Peru, there have not been any studies on the use of the Glasgow-Blatchford Scoring System to predict mortality in upper gastrointestinal bleeding. The aim of this study is to perform an external validation of the Glasgow-Blatchford Scoring System and to establish the best cutoff for predicting mortality in upper gastrointestinal bleeding in a hospital of Lima, Peru.

METHODS

This was a longitudinal, retrospective, analytical validation study, with data from patients with a clinical and endoscopic diagnosis of upper gastrointestinal bleeding treated at the Gastrointestinal Hemorrhage Unit of the Hospital Nacional Edgardo Rebagliati Martins between June 2012 and December 2013. We calculated the area under the curve for the receiver operating characteristic of the Glasgow-Blatchford Scoring System to predict mortality with a 95% confidence interval.

RESULTS

A total of 339 records were analyzed. 57.5% were male and the mean age (standard deviation) was 67.0 (15.7) years. The median of the Glasgow-Blatchford Scoring System obtained in the population was 12. The ROC analysis for death gave an area under the curve of 0.59 (95% CI 0.5-0.7). Stratifying by type of upper gastrointestinal bleeding resulted in an area under the curve of 0.66 (95% CI 0.53-0.78) for non-variceal type.

CONCLUSIONS

In this population, the Glasgow-Blatchford Scoring System has no diagnostic validity for predicting mortality.

Comparison of the efficacy of two combined therapies for peptic ulcer bleeding: adrenaline injection plus haemoclipping versus adrenaline injection followed by bipolar electrocoagulation

INTRODUCTION

Peptic ulcer remains the most frequent cause of upper gastrointestinal bleeding. Treatment of bleeding with simultaneous combination of two endoscopic techniques has proved to be more efficient than monotherapy. None of the published comparative studies of various contact coagulation modalities have confirmed the superiority of one of these techniques over the others.

AIM

To compare the therapeutic outcomes of the use of a device enabling both injection of adrenaline solution and bipolar electrocoagulation (A + BE) to those of combined adrenaline injection with mechanical therapy (haemostatic clips) (A + HC) in the treatment of peptic ulcer bleeding.

MATERIAL AND METHODS

Fifty-two subjects with bleeding ulcers were assigned to the A + BE group, and 55 patients were treated with A + HC.

RESULTS

Overall, treatment failed in 20 patients (20/107, 18.7%): in 10 individuals from the A + BE group (10/52; 18.2%) and in 10 individuals from the A + HC group (10/55; 19.2%) (p > 0.05). Primary haemostasis was not obtained in 7 patients (6.5%): in 4 patients in the A + BE group and in 3 patients in the A + HC group (p > 0.05). Ten individuals (9.3%) experienced recurrent bleeding during hospitalisation: 4 patients from the A + BE group and 6 patients from the A + HC group (p > 0.05). Finally, in 96.3% of the patients (n = 103) the endoscopic treatment proved efficient with regards to obtaining haemostasis during hospitalisation. Surgical intervention was required in 4 individuals (3.7%): 2 patients in the A + BE group and 2 patients treated with A + HC (p > 0.05). Three patients (2.8%) - all from the A + HC group - died during hospitalisation. No significant intergroup differences were documented with regards to the mean number of transfused blood units and the mean length of hospital stay.

CONCLUSIONS

The efficacy of combined endoscopic treatment of ulcer bleeding with a probe enabling simultaneous bipolar electrocoagulation and adrenaline injection seems comparable to the widely used dual technique of adrenaline injection and haemostatic clipping.

One fifth of hospitalizations for peptic ulcer-related bleeding are potentially preventable

AIM: To calculate the proportion of potentially preventable hospitalizations due to peptic ulcer disease (PUD), erosive gastritis (EG) or duodenitis (ED).

METHODS: Retrospective cohort study using ICD-10 codes to identify all patients with upper gastrointestinal hemorrhage secondary to endoscopically proven PUD, EG or ED during the period from March 2007 to October 2010 in three major metropolitan hospitals in Melbourne, Australia. Patients were divided into “high risk” (those who would benefit from gastroprotection) and “not high risk” groups as defined by established guidelines. Mean Rockall score, transfusion requirement, length of stay, rebleeding rates, need for surgery and in-hospital mortality was compared between “high risk” and “not high risk” groups. Within the “high risk” group, those on gastroprotection and those with no gastroprotection were also compared.

RESULTS: Five hundred and seven patients were included for analysis of which 174 were classified as high risk. Median values of complete Rockall Score (5 vs 4, P = 0.002) and length of stay (5 d vs 4 d, P = 0.04) were higher in the high risk group but in-hospital mortality was lower (0.6% vs 3.9%, P = 0.03). 130 out of the 174 patients in the high risk group were not taking recommended gastroprotective therapy prior to hospitalization. Past history of PUD (OR = 3.7, P = 0.006) and clopidogrel use (OR = 3.2, P = 0.007) significantly predicted prescription of gastroprotective therapy. Using proton pump inhibitor protection rates of 50%-85% from published studies, an estimation of 13% to 22% of the total number of the hospitalizations due to PUD or EG/ED related bleeding may have been preventable.

CONCLUSION: Up to one fifth of all hospitalizations for bleeding secondary to PUD or EG/ED are potentially preventable.

Endoscopy for nonvariceal upper gastrointestinal bleeding

Endoscopy for acute nonvariceal upper gastrointestinal bleeding plays an important role in primary diagnosis and management, particularly with respect to identification of high-risk stigmata lesions and to providing endoscopic hemostasis to reduce the risk of rebleeding and mortality. Early endoscopy, defined as endoscopy within the first 24 hours after presentation, improves patient outcome and reduces the length of hospitalization when compared with delayed endoscopy. Various endoscopic hemostatic methods are available, including injection therapy, mechanical therapy, and thermal coagulation. Either single treatment with mechanical or thermal therapy or a treatment that combines more than one type of therapy are effective and safe for peptic ulcer bleeding. Newly developed methods, such as Hemospray powder and over-the-scope clips, may provide additional options. Appropriate decisions and specific treatment are needed depending upon the conditions.

Use of the Complete Rockall Score and the Forrest Classification to Assess Outcome in Patients with Non-variceal Upper Gastrointestinal Bleeding Subject to After-hours Endoscopy: A Retrospective Cohort Study

OBJECTIVES

To evaluate the usefulness of the Forrest classification and the complete Rockall score with customary cut-off values for assessing the risk of adverse events in patients with upper gastrointestinal bleeding (UGI-B) subject to after-hours emergency oesophago-gastro-duodenoscopy (E-EGD) within six hours after admission.

METHODS

The medical records of patients with non-variceal UGI-B proven by after-hours endoscopy were analysed. For 'high risk' situations (Forrest stage Ia-IIb/complete Rockall score > 2), univariate analysis was conducted to evaluate odds ratio for reaching the study endpoints (30-day and one-year mortality, re-bleeding, hospital stay ≥ 3 days).

RESULTS

During the study period (75 months), 86 cases (85 patients) met the inclusion criteria. Patients' age was 66.36 ± 14.38 years; 60.5% were male. Mean duration of hospital stay was 15.21 ± 19.24 days. Mortality rate was 16.7% (30 days) and 32.9% (one year); 14% of patients re-bled. Univariate analysis of post-endoscopic Rockall score ≥ 2 showed an odds ratio of 6.09 for death within 30 days (p = 0.04). No other significant correlations were found.

CONCLUSION

In patients with UGI-B subject to after-hours endoscopy, a 'high-risk' Rockall score permits an estimation of the risk of death within 30 days but not of re-bleeding. A 'high-risk' Forrest score is not significantly associated with the study endpoints.

Rockall score in predicting outcomes of elderly patients with acute upper gastrointestinal bleeding

AIM: To validate the clinical Rockall score in predicting outcomes (rebleeding, surgery and mortality) in elderly patients with acute upper gastrointestinal bleeding (AUGIB).

METHODS: A retrospective analysis was undertaken in 341 patients admitted to the emergency room and Intensive Care Unit of Xuanwu Hospital of Capital Medical University with non-variceal upper gastrointestinal bleeding. The Rockall scores were calculated, and the association between clinical Rockall scores and patient outcomes (rebleeding, surgery and mortality) was assessed. Based on the Rockall scores, patients were divided into three risk categories: low risk ≤ 3, moderate risk 3-4, high risk ≥ 4, and the percentages of rebleeding/death/surgery in each risk category were compared. The area under the receiver operating characteristic (ROC) curve was calculated to assess the validity of the Rockall system in predicting rebleeding, surgery and mortality of patients with AUGIB.

RESULTS: A positive linear correlation between clinical Rockall scores and patient outcomes in terms of rebleeding, surgery and mortality was observed (r = 0.962, 0.955 and 0.946, respectively, P = 0.001). High clinical Rockall scores > 3 were associated with adverse outcomes (rebleeding, surgery and death). There was a significant correlation between high Rockall scores and the occurrence of rebleeding, surgery and mortality in the entire patient population (χ² = 49.29, 23.10 and 27.64, respectively, P = 0.001). For rebleeding, the area under the ROC curve was 0.788 (95%CI: 0.726-0.849, P = 0.001); For surgery, the area under the ROC curve was 0.752 (95%CI: 0.679-0.825, P = 0.001) and for mortality, the area under the ROC curve was 0.787 (95%CI: 0.716-0.859, P = 0.001).

CONCLUSION: The Rockall score is clinically useful, rapid and accurate in predicting rebleeding, surgery and mortality outcomes in elderly patients with AUGIB.

A prospective comparison of 3 scoring systems in upper gastrointestinal bleeding

BACKGROUND

The clinical severities of upper gastrointestinal bleeding (UGIB) are of a wide variety, ranging from insignificant bleeds to fatal outcomes. Several scoring systems have been designed to identify UGIB high- and low-risk patients. The aim of our study was to compare the Glasgow-Blatchford score (GBS) with the preendoscopic Rockall score (PRS) and the complete Rockall score (CRS) in their utilities in predicting clinical outcomes in patients with UGIB.

METHODS

We designed a prospective study to compare the performance of the GBS, PRS, and CRS in predicting primary and secondary outcomes in UGIB patients. The primary outcome included the need for blood transfusion, endoscopic therapy, or surgical intervention and was labeled as high risk. The secondary outcomes included rebleeding and 30-day mortality. The area under the receiver operating characteristic curve (AUC), sensitivity, specificity, and positive and negative predictive values for each system were analyzed. A total of 303 consecutive patients admitted with UGIB during a 1-year period were enrolled.

RESULTS

For prediction of high-risk group, AUC was obtained for GBS (0.808), PRS (0.604), and CRS (0.767). For prediction of rebleeding, AUC was obtained for GBS (0.674), PRS (0.602), and CRS (0.621). For prediction of mortality, AUC was obtained for GBS (0.513), PRS (0.703), and CRS (0.620).

CONCLUSIONS

In detecting high-risk patients with acute UGIB, GBS may be a useful risk stratification tool. However, none of the 3 score systems has good performance in predicting rebleeding and 30-day mortality because of low AUCs.

Upper Gastrointestinal Hemorrhage: Development of the Severity Score

Background

Emergency endoscopy for every patient with upper gastrointestinal hemorrhage is not possible in many medical centers. Simple guidelines to select patients for emergency endoscopy are lacking. The aim of the present report is to develop a simple scoring system to classify upper gastrointestinal hemorrhage (UGIH) severity based on patient clinical profiles at the emergency departments.

Methods

Retrospective data of patients with UGIH in a university affiliated hospital were analyzed. Patients were criterion-classified into 3 severity levels: mild, moderate and severe. Clinical and laboratory information were compared among the 3 groups. Significant parameters were selected as indicators of severity. Coefficients of significant multivariable parameters were transformed into item scores, which added up as individual severity scores. The scores were used to classify patients into 3 urgency levels: non-urgent, urgent and emergent groups. Score-classification and criterion-classification were compared.

Results

Significant parameters in the model were age ≥ 60 years, pulse rate ≥ 100/min, systolic blood pressure < 100 mmHg, hemoglobin < 10 g/dL, blood urea nitrogen ≥ 35 mg/dL, presence of cirrhosis and hepatic failure. The score ranged from 0 to 27, and classifying patients into 3 urgency groups: non-urgent (score < 4, n = 215, 21.2%), urgent (score 4 - 16, n = 677, 66.9%) and emergent (score > 16, n = 121, 11.9%). The score correctly classified 81.4% of the patients into their original (criterion-classified) severity groups. Under-estimation (7.5%) and over-estimation (11.1%) were clinically acceptable.

Conclusions

Our UGIH severity scoring system classified patients into 3 urgency groups: non-urgent, urgent and emergent, with clinically acceptable small number of under- and over-estimations. Its discriminative ability and precision should be validated before adopting into clinical practice.

Clinical Risk Characteristics of Upper Gastrointestinal Hemorrhage Severity: A Multivariable Risk Analysis

Background

Upper gastrointestinal hemorrhage (UGIH) is one of the common clinical manifestations encountered in most emergency departments. Patient characteristics indicating UGIH severity in developing countries may be different from those in developed countries. The present study was designed to explore clinical prognostic indicators for UGIH severity.

Methods

A retrospective cohort study was conducted in a university affiliated tertiary hospital in Kamphaeng Phet, Thailand. Medical folders of patients with UGIH were reviewed. Patients were grouped into 3 severity levels, based on criteria proposed by The American College of Surgeon. Pre-defined prognostic indicators were compared. The prognostic indicators for UGIH severity were analyzed by a multivariable continuation ratio ordinal logistic regression and presented with odds ratios.

Results

From 1,043 eligible medical folders, 984 (94.3%) complete folders were used in analysis. There were 241, 631 and 112 patients in the mild, moderate and severe UGIH groups. Six independent indicators of severe UGIH were, hemoglobin < 100 g/dL (OR = 13.82, 95% CI = 9.40 to 20.33, P < 0.001), systolic blood pressure < 100 mmHg (OR = 11.01, 95% CI = 7.41 to 16.36, P < 0.001), presence of hepatic failure (OR = 5.50, 95% CI = 1.14 to26.64, P = 0.037), presence of cirrhosis (OR = 2.03, 95% CI = 1.32 to 3.11, P = 0.001), blood urea nitrogen ≥ 35 mmol/L (OR = 1.73, 95% CI = 1.25 to 2.40, P = 0.001), and pulse rate ≥ 100 per minute (OR = 1.72, 95% CI = 1.21 to 2.45, P = 0.003).

Conclusions

Pulse rate ≥ 100 per minute, systolic blood pressure < 100 mmHg, hemoglobin < 10 g/dL, blood urea nitrogen ≥ 35 mmol/L, presence of cirrhosis and presence of hepatic failure are prognostic indicators for an increase in UGIH severity levels. They are potentially useful in UGIH risk stratification.

Predictive validity of the Glasgow Blatchford Bleeding Score in an unselected emergency department population in continental Europe

BACKGROUND AND AIM

Glasgow Blatchford Bleeding Score stratifies patients presenting with acute upper gastrointestinal haemorrhage at the emergency department according to the likelihood of the need for treatment. The objective of this study was to validate the Glasgow Blatchford Bleeding Score for use in an emergency department in the Netherlands. Furthermore, we assessed its clinical usefulness for safe discharge of low-risk acute upper gastrointestinal haemorrhage patients and compared its test validity to that of other scoring systems.

METHODS

This multicentre historic cohort study was conducted in two hospitals in the Netherlands. All 478 patients presenting with a suspicion of acute upper gastrointestinal haemorrhage at our emergency departments during a 1-year period were included. For each patient we calculated Glasgow Blatchford Bleeding Score and other commonly used scores. Test validity was assessed using the receiver operated characteristics curve analysis; calibration plots were used to assess the probability of the need for treatment of different levels of the scores.

RESULTS

Glasgow Blatchford Bleeding Score had a good discriminative ability in predicting the need for treatment, receiver operated characteristics curve analysis showed an area under the curve of 0.879. Counting a score of 2 or less as low risk (negative), 104 patients (21.7%) were classified as low-risk, with a negative predictive value of 98.1%. These results were superior to those of the other scoring systems.

CONCLUSION

Patients presenting at an emergency department in continental Europe with acute upper gastrointestinal haemorrhage and a Glasgow Blatchford Bleeding Score of 2 or less can be safely discharged. The Glasgow Blatchford Bleeding Score performed better than the other commonly used scoring systems.

Diagnosis and management of nonvariceal upper gastrointestinal bleeding

Nonvariceal upper gastrointestinal bleeding (UGIB) is a major cause of morbidity and mortality worldwide. Despite the improvements in the management of this condition in western countries, mortality rates have remained at 5-10% over the past decade. This article presents the main recommendations for the management of UGIB. Pre-endoscopic management (including use of scoring scales, nasogastric tube placement and blood pressure stabilization) is crucial for triage and optimal resuscitation of patients, and should include a multidisciplinary approach at an early stage. Unless the patient has specific comorbidities, transfusion should only be considered if their hemoglobin level is ≤70 g/l. Endoscopic therapy, the cornerstone of therapeutic management of high-risk lesions, should not be delayed for more than 24 h following admission. Several endoscopic techniques, mostly using clips or thermal methods, are available and new approaches are emerging. When endoscopy fails, surgery or arterial embolization should be considered. Although the efficacy of prokinetics and high-dose intravenous PPI prior to endoscopy is controversial, the use of an intravenous PPI following endoscopy is strongly recommended. Antiplatelet therapy should be suspended and resumed in 3-5 days. Finally, all patients should be tested for Helicobacter pylori by serology in the acute setting.

[Surgical intervention in acute upper gastrointestinal bleeding]

BACKGROUND AND PURPOSE

Acute gastrointestinal bleeding (AGIB) requiring transfusion and surgical treatment still constitutes a life-threatening situation. The purpose of this paper was to examine the treatment outcome for this group of patients as a function of various risk factors and to present our diagnostic and therapeutic regime.

METHODS

A retrospective analysis of data from 154 patients with AGIB who underwent surgical procedures and received massive transfusions in a university hospital between 1999 and 2008 was carried out.

RESULTS

The patients were divided into two groups. Group I include 91 patients with acute upper gastrointestinal bleeding and group II included 63 patients with lower gastrointestinal bleeding. The average age was 67 years (range 29-93 years) in group I and 70 years (39-97 years) in group II. The initial hemoglobin level was 8.4 g/dl in group I and 10.5 g/dl in group II. Univariate analysis of mortality revealed the following significant risk factors for group I: postoperative need for ventilation (p=0.007), prolonged ICU stay (p=0.004) and anticoagulants in the medical history. The risk factors in group II were blood transfusions >10 units (p=0.031), postoperative need for ventilation (p=0.004), necessary reoperations (p=0.016) and an initial hemoglobin level <8.0 g/dl (p=0.043). The complication rate was 76.9% (mortality rate 34.1%) in group I and 60.3% (mortality rate 15.9%) in group II.

CONCLUSIONS

Examination and stabilization of the patient is directly followed by diagnostic localization. The indication for surgery is mainly limited to peracute, uncontrollable and recurrent forms of gastrointestinal bleeding. The mortality rate for these critically ill, negatively selected patients remains high and could not be lowered in the last decade. Postoperative need of ventilation is a predictor for poor prognosis.

The Glasgow Blatchford scoring system enables accurate risk stratification of patients with upper gastrointestinal haemorrhage

BACKGROUND

Upper gastrointestinal (UGI) haemorrhage is a frequent cause of hospital admission. Scoring systems have been devised to identify those at risk of adverse outcomes. We evaluated the Glasgow Blatchford score's (GBS) ability to identify the need for clinical and endoscopic intervention in patients with UGI haemorrhage.

METHODS

A retrospective observational study was performed in all patients who attended the A&E department with UGI haemorrhage during a 12-month period. Patients were separated into low and high risk categories. High risk encompassed patients who required blood transfusions, operative or endoscopic interventions, management on high dependency or intensive care units, and those who re-bled, represented with further bleeding, or who died.

RESULTS

A total of 174 patients were seen with UGI bleeding. Eight of them self-discharged and were excluded. Of the remaining 166, 94 had a 'low risk' bleed, and 72 'high risk'. The GBS was significantly higher in the high risk (median = 10) than in the low risk group (median 1, p < 0.001). To assess the validity of the GBS at separating low and high risk groups, receiver-operator characteristic (ROC) curves were plotted. The GBS had an area under ROC curve of 0.96 (95% CI 0.95-1.00). When a cut-off value of > or = 3 was used, sensitivity and specificity of GBS for identifying high risk bleeds was 100% and 68%. Thus at a cut-off value of < or = 2 the GBS is useful for distinguishing those patients with a low risk UGI bleed.

CONCLUSIONS

The GBS accurately identifies low risk patients who could be managed safely as outpatients.

Melaena with Peutz-Jeghers syndrome: a case report

Introduction

Peutz-Jeghers syndrome (PJS) is a rare familial disorder characterised by mucocutaneous pigmentation, gastrointestinal and extragastrointestinal hamartomatous polyps and an increased risk of malignancy. Peutz-Jeghers polyps in the bowel may result in intussusception. This complication usually manifests with abdominal pain and signs of intestinal obstruction.

Case Presentation

We report the case of a 24-year-old Caucasian male who presented with melaena. Pigmentation of the buccal mucosa was noted but he was pain-free and examination of the abdomen was unremarkable. Upper gastrointestinal endoscopy revealed multiple polyps. An urgent abdominal computed tomography (CT) scan revealed multiple small bowel intussusceptions. Laparotomy was undertaken on our patient, reducing the intussusceptions and removing the polyps by enterotomies. Bowel resection was not needed.

Conclusion

Melaena in PJS needs to be urgently investigated through a CT scan even in the absence of abdominal pain and when clinical examination of the abdomen shows normal findings. Although rare, the underlying cause could be intussusception, which if missed could result in grave consequences.

Predictive factors for rebleeding and death in alcoholic cirrhotic patients with acute variceal bleeding: a multivariate analysis

BACKGROUND

Bleeding from esophageal varices is a leading cause of death in alcoholic cirrhotic patients. The aim of the present single-center study was to identify risk factors predictive of variceal rebleeding and death within 6 weeks of initial treatment.

METHODS

Univariate and multivariate analyses were performed on 310 prospectively documented alcoholic cirrhotic patients with acute variceal hemorrhage (AVH) who underwent 786 endoscopic variceal injection treatments between January 1984 and December 2006. All injections were administered during the first 6 weeks after the patients were treated for their first variceal bleed.

RESULTS

Seventy-five (24.2%) patients experienced a rebleed, 38 within 5 days of the initial treatment and 37 within 6 weeks of their initial treatment. Of the 15 variables studied and included in a multivariate analysis using a logistic regression model, a bilirubin level >51 mmol/l and transfusion of >6 units of blood during the initial hospital admission were predictors of variceal rebleeding within the first 6 weeks. Seventy-seven (24.8%) patients died, 29 (9.3%) within 5 days and 48 (15.4%) between 6 and 42 days after the initial treatment. Stepwise multivariate logistic regression analysis showed that six variables were predictors of death within the first 6 weeks: encephalopathy, ascites, bilirubin level >51 mmol/l, international normalized ratio (INR) >2.3, albumin <25 g/l, and the need for balloon tube tamponade.

CONCLUSIONS

Survival was influenced by the severity of liver failure, with most deaths occurring in Child-Pugh grade C patients. Patients with AVH and encephalopathy, ascites, bilirubin levels >51 mmol/l, INR >2.3, albumin <25 g/l and who require balloon tube tamponade are at increased risk of dying within the first 6 weeks. Bilirubin levels >51 mmol/l and transfusion of >6 units of blood were predictors of variceal rebleeding.

The Comprehensive Geriatric Assessment and the multidimensional approach. A new look at the older patient with gastroenterological disorders

The Comprehensive Geriatric Assessment (CGA) is a multidimensional, usually interdisciplinary, diagnostic process intended to determine an elderly person's medical, psychosocial, and functional capacity and problems with the objective of developing an overall plan for treatment and short- and long-term follow-up. The potential usefulness of the CGA in evaluating treatment and follow-up of older patients with gastroenterological disorders is unknown. In the paper we reported the efficacy of a Multidimensional-Prognostic Index (MPI), calculated from information collected by a standardized CGA, in predicting mortality risk in older patients hospitalized with upper gastrointestinal bleeding and liver cirrhosis. Patients underwent a CGA that included six standardized scales, i.e. Activities of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Short-Portable Mental Status Questionnaire (SPMSQ), Mini-Nutritional Assessment (MNA), Exton-Smith Score (ESS) and Comorbity Index Rating Scale (CIRS), as well as information on medication history and cohabitation, for a total of 63 items. The MPI was calculated from the integrated total scores and expressed as MPI 1=low risk, MPI 2=moderate risk and MPI 3=severe risk of mortality. Higher MPI values were significantly associated with higher short- and long-term mortality in older patients with both upper gastrointestinal bleeding and liver cirrhosis. A close agreement was found between the estimated mortality by MPI and the observed mortality. Moreover, MPI seems to have a greater discriminatory power than organ-specific prognostic indices such as Rockall and Blatchford scores (in upper gastrointestinal bleeding patients) and Child-Plugh score (in liver cirrhosis patients). All these findings support the concept that a multidimensional approach may be appropriate for the evaluation of older patients with gastroenterological disorders, like it has been reported for patients with other pathological conditions.

Dedicated bleed units: should they be advocated?

BACKGROUND

Upper gastrointestinal haemorrhage (UGIH) is a common emergency, however, dedicated bleed units only exist in selected hospitals in the UK.

OBJECTIVE

To evaluate the rebleeding and mortality rate of patients admitted with UGIH to a tertiary centre bleed unit in comparison with the current national standards and earlier unit performance in 1995-1998.

METHODS

A retrospective case note review of demographics, the Rockall scores and final outcome was conducted for all patients admitted to the bleed unit over 24 months.

RESULTS

Two hundred and fifty-five cases were identified with a mean age of 62 years and a median Rockall score of 3. Eighty-two percent of gastroscopies were performed within 24 h. Of these, 29% were undertaken after 5 p.m. Peptic ulcer and varices (15%) were the commonest diagnosis. The rebleeding (12%) and mortality rate (9%) were comparable with that of the units previous audit (P=0.47, 0.51, respectively) and the current national audit (P=0.58, 0.76, respectively). The number of patients requiring surgery has reduced from 6 to 0.4% in our unit over the last 8 years. Preendoscopy and postendoscopy Rockall scores were predictive of rebleeding (P=0.013, 0.045) and mortality (P=0.003, 0.01).

CONCLUSION

This study has shown a consistently low rebleeding and mortality rate in patients with UGIH in a dedicated bleed unit. However there are limitations to the degree of improvements which can be demonstrated due to factors such as age and comorbidity.
