INTRODUCTION Early feeding was previously considered to increase the risk of postprocedural bleeding. However, many trials have demonstrated the benefits of early feeding after therapeutic endoscopic procedures. We conducted a meta-analysis of randomized controlled trials to evaluate the safety and outcomes between early feeding and delayed feeding after therapeutic endoscopic procedures. METHODS Medline (PubMed), Embase, Google Scholar, the Cochrane Library, and clinicaltrials.gov were searched to identify randomized controlled trials that met our inclusion criteria. The pooled data for the mortality rate, postprocedural bleeding rate, and length of hospital stay were analyzed. RESULTS A total of seven trials consisting of 717 patients were reviewed. These seven trials examined various therapeutic endoscopic procedures. Three trials included patients undergoing endoscopic hemostasis for upper gastrointestinal bleeding, two included patients undergoing esophageal variceal ligation, and two included patients with gastric neoplasm treated with endoscopic submucosal dissection. Although no significant differences were observed in the postprocedural bleeding rate or the mortality rate between patients who received early feeding and those who received delayed feeding, early feeding resulted in shorter hospital stays (weighted mean difference -1.04, 95% confidence interval -1.45 to 0.63). CONCLUSION Early feeding appears to be a safe management method for patients undergoing therapeutic endoscopic procedures. Therefore, we recommend early feeding for these patients.

Background The long-term effects of H. pylori eradication in preventing upper GI bleeding (UGIB) remains unknown. Aim To determine the long-term risks of UGIB after H. pylori eradication METHODS: We included all patients who had received clarithromycin-containing triple therapy for the treatment of H. pyliori infection between 2003 and 2012, without subsequent need for re-treatment. We included a propensity score (PS)-matched endoscopy cohort of H. pylori-negative patients as controls. The primary endpoint was the risk of subsequent UGIB. A multivariable Cox model was used to compute the hazard ratio (HR) of UGIB. Results We included 62 738 H. pylori-eradicated and 62 738 PS-matched H. pylori-negative patients, with a median follow-up of 8.1 years (IQR 5.5-10.6). The incidence of UGIB was 20.8 (95% CI 19.5-22.1) and 13.6 (95% CI 12.7-14.7) per 10 000 person-years in H. pylori-eradicated and H. pylori-negative patients, respectively. Compared to controls, H. pylori-eradicated patients had a significantly higher risk of UGIB (HR: 1.65, 95% CI 1.49-1.83). The risk of UGIB in H. pylori-eradicated patients increased after the first 2 years of follow up (HR: 2.18, 95% CI 1.91-2.49). Age-stratified analysis showed that patients >45 years had higher UGIB risk, even after eradication. Conclusions Despite H. pylori eradication, the long-term risk of UGIB was still higher than in H. pylori-negative control subjects. The protective effects of eradication therapy in preventing UGIB appeared to be limited to younger patients, and to within the first 2 years after eradication.

Background and Aim: Upper gastrointestinal bleeding (UGIB) is a common gastrointestinal emergency and carries high morbidity and mortality. There are multiple risk factors for poorer outcomes, including malnutrition. Ascorbic acid is a water-soluble vitamin present in most plant foods. Dietary deficiency leads to scurvy, which may alter the natural history of UGIB through impaired tissue and mucosal integrity. Traditionally thought to be rare in developed countries, vitamin C deficiency (VCD) is now well described in patients with pneumonia, sepsis, and coronavirus disease 2019. There is a paucity of literature investigating the prevalence and clinical significance of VCD in patients with UGIB;interim findings reported by our group suggested a prevalence of >30%. The aim of this study was to establish the prevalence of VCD in patients presenting with UGIB and its association with clinical outcomes. Methods: We conducted a prospective cohort study of adult patients presenting with UGIB to two metropolitan tertiary hospitals in Melbourne, Australia, over a 12-month period (March 2020 to March 2021). Fasting vitamin C levels were obtained on admission. Patients were risk-stratified using the AIMS65 score, and baseline demographic data and outcomes were recorded. The primary outcome was the prevalence of VCD (serum vitamin C level < 23 μmol/L) and severe VCD (

BACKGROUND: Previous studies have demonstrated the seasonal variations of non-variceal upper gastrointestinal bleeding (UGIB), but there is scanty data on lower gastrointestinal bleeding (LGIB) and the association with other meteorological parameters.METHODS: We included all patients hospitalized for UGIB and LGIB between 2009 and 2018 in Hong Kong. The monthly age-standardized and sex-standardized GIB incidences were fitted to meteorological data including average temperature (AT), maximum temperature (MaxT), minimum temperature (MinT), temperature range (TR), average precipitation, average atmospheric pressure (AtomP), and average relative humidity after adjusting for prescriptions of aspirin, proton pump inhibitors, and Helicobacter pylori eradication therapy using the autoregressive integrated moving average model.RESULTS: Despite a gradual decline in UGIB incidences, the incidences of UGIB were still higher in winter months. The incidence and fluctuation of both UGIB and LGIB were higher in the older age groups, especially those ≥80 years. The seasonality was only identified in those ≥60 years for UGIB, and only in those ≥80 years for LGIB. UGIB incidence was inversely associated with AT, MaxT, and MinT, but positively associated with TR and AtomP. LGIB was also significantly associated with AT, MaxT, MinT, and AtomP.CONCLUSION: Despite the changes in GIB incidences, the seasonal patterns of GIB were still marked in the elderly. With the aging population, the impacts of seasonal variations on GIB incidences could be considerable.

Background and Aim: Upper gastrointestinal tumors account for 5% of upper gastrointestinal bleeds. These patients are challenging to treat due to the diffuse nature of the neoplastic bleeding lesions, high rebleeding rates, and significant transfusion requirements. TC-325 (Cook Medical, North Carolina, USA) is a hemostatic powder for gastrointestinal bleeding. The aim of this study was to examine the outcomes of upper gastrointestinal bleeds secondary to tumors treated with Hemospray therapy. Methods: Data were prospectively collected on the use of Hemospray from 17 centers. Hemospray was used during emergency endoscopy for upper gastrointestinal bleeds secondary to tumors at the discretion of the endoscopist as a monotherapy, dual therapy with standard hemostatic techniques, or rescue therapy. Results: One hundred and five patients with upper gastrointestinal bleeds secondary to tumors were recruited. The median Blatchford score at baseline was 10 (interquartile range [IQR], 7–12). The median Rockall score was 8 (IQR, 7–9). Immediate hemostasis was achieved in 102/105 (97%) patients, 15% of patients had a 30-day rebleed, 20% of patients died within 30 days (all-cause mortality). There was a significant improvement in transfusion requirements following treatment (P

Objectives Patients who develop upper gastrointestinal bleeding (UGIB) while in hospital appear to have a poor prognosis. Our study aims at analysing the difference in outcome between in‐patients (IPs) and out‐patients presenting with variceal and non‐variceal UGIB. Methods We conducted a multicentre prospective study by collecting data about variceal and non‐variceal UGIB cases through 46 hospitals in France between November 2017 and October 2018. We then compared baseline demographic features, endoscopic findings and outcome between patients who developed variceal and non‐variceal UGIB on admission (OPs) and those at least 24 h after hospitalisation (IPs). Our primary end‐point was mortality and re‐bleeding rates at 6 weeks of bleeding onset. Results A total of 2498 UGIB cases were identified, of whom 634 (25.4%) occurred in IPs. IPs were older than OPs (72.5 vs. 67.2 years old, p 5 present in 40.9% (vs. 30.3% in OPs, p 11 (p = 0.017, 0.011 and 0.008, respectively). Conclusion IPs who develop variceal and non‐variceal UGIB are more likely to be elderly with more comorbidities. They have a higher rate of mortality and rebleeding. Independent predictors of mortality were underlying coagulopathy and bleeding recurrence. An optimal bleeding management and efficient rebleeding prevention may improve outcome in these patients., Key Point Summarize the established knowledge on this subject Upper gastrointestinal bleeding (UGIB) in already hospitalised patients (IPs) appears to have a worse prognosis when compared to UGIB in out‐patients (OPs).Few studies have addressed this issue, most of which are retrospective. They found a poor short‐term outcome in IPs without being able to identify modifiable risk factors that could affect the prognosis. Significant and/or new findings of this study? We demonstrated in this prospective and multicentre study a greater 6‐week mortality and rebleeding rates in IPs versus OPs.IPs were older and had a higher rate of comorbidities. Prothrombin time

BACKGROUND AND AIM Several scoring systems for predicting outcomes in patients with non-variceal upper gastrointestinal bleeding (NVUGIB) have recently been devised, but not sufficiently validated. We compared the predictive accuracy of several scoring systems and assessed the usefulness of new scoring systems. METHODS The medical records of 1048 patients with NVUGIB were reviewed to collect demographic, clinical, laboratory, and endoscopic data. The areas under the receiver operating characteristic curve (AUROCs) were calculated for the ABC, new Japanese scoring system, Progetto Nazionale Emorrhagia Digestiva (PNED), and other scores to compare their predictive accuracy for 30-day mortality, therapeutic intervention, rebleeding, and prolonged hospital stay (≥ 10 days). Outcome predictors were identified by multivariate analysis. RESULTS The ABC, new Japanese scoring system, and PNED scores best predicted 30-day mortality (AUROC 0.907), need for therapeutic intervention (AUROC 0.707), and rebleeding (AUROC 0.874), respectively (all P

BACKGROUND AND AIM Hemosuccus pancreaticus is considered as one of the rare cause of upper gastrointestinal bleeding. Intermittent nature of bleeding and lack of standardized approach for diagnosis has resulted in significant delay in definitive management. METHODS We retrospectively analyzed prospectively maintained data of patients with suspected hemosuccus pancreaticus between January 2010 and December 2019. RESULTS Out of 114 patients, 87 patients were diagnosed with hemosuccus pancreaticus. Mean age was 35.7 ± 11.7 years with 89.7% men. Median duration of bleeding before diagnosis was 10 days, with 40.2%, 10.3%, and 5.7% patients had symptoms beyond 1, 6, and 12 months, respectively. Visceral artery aneurysm was noted in 62% of cases with splenic artery aneurysm (37.9%) being the common source of bleed. Rarer causes noted were superior mesenteric artery aneurysm, pancreatic adenocarcinoma, gastrointestinal stromal tumor, and post-endoscopic retrograde cholangiopancreatography (2.3% each). Santorinirrhage was seen in 3.4% patients. Endoscopic diagnosis was possible in 64.4% of patients, and angiogram localization of bleeding source was noted in 94.2%. A 56.3% of patients underwent conventional angioembolization with 95.9% success and 28.7% underwent surgery, with overall rebleeding rate of 11.5%. CONCLUSIONS Early diagnosis of hemosuccus pancreaticus avoids prolonged suffering, multiple hospital admissions, and multiple blood transfusions. It is not uncommon in the absence of aneurysm. In cases of high suspicion, repeating the endoscopy with proper technique and proper timing increases the yield. Angioembolization remains the most preferred first line therapeutic approach in majority of cases.

BACKGROUND AND AIM Clopidogrel is widely prescribed for patients with of aspirin-related upper gastrointestinal bleeding (UGIB) history. This study aimed to compare the risk of a major adverse cardiovascular event (MACE), UGIB, and mortality between aspirin and clopidogrel in patients at risk of bleeding. METHODS We analyzed adult patients at high risk of UGIB following aspirin-related bleeding for secondary MACE prevention between 2000 and 2012. Secondary prevention was for those patients who had ever been hospitalized for cardiovascular disease and reused aspirin or changed to clopidogrel after discharge. Study endpoints were recurrence of MACE, UGIB, and death in 90 days of follow-up. The associations between study outcomes and the use of clopidogrel (vs aspirin) were analyzed. RESULTS Among 947 eligible patients, 653 reused aspirin (in combination with a proton-pump inhibitor), and 294 were treated with clopidogrel (in combination with a proton-pump inhibitor) after discharge for UGIB. Compared with aspirin treatment, clopidogrel showed an increased risk of MACE (adjusted hazard ratio [aHR] 1.65; 95% confidence interval [CI] 0.87-3.12) and UGIB (aHR 1.25; 95% CI 0.66-2.36), but without statistical significance in 90 days' follow-up. Clopidogrel use was associated with greater than four times the risk of any cause of mortality (aHR 4.84; 95% CI 1.59-14.75), but the significance did not hold in propensity score-matched cohort analysis (P = 0.06). CONCLUSIONS A nonsignificant difference between clopidogrel and aspirin for short-term MACE prevention as well as UGIB recurrence was found in the present study. Further research to assess 90-day mortality would assist clinical decision making.

Summary\ud Background: Upper gastrointestinal bleeding is a common medical emergency associated with substantial mortality. \ud Tranexamic acid may be effective for reducing mortality in upper gastrointestinal bleeding.\ud Aim: To examine the effects of tranexamic acid in upper gastrointestinal bleeding by systematic review and meta-analysis.\ud Methods: We searched PubMed, EMBASE, CINAHL, the Cochrane Central Register of Controlled Trials (CENTRAL) and other relevant websites for randomised controlled trials investigating the effect of tranexamic acid published from inception to\ud December 10, 2019. The primary outcome of interest was mortality. Estimates of effect were pooled with a random effects model. Quality of evidence was assessed using the Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach.\ud Results: The search identified 1572 citations. Eleven trials comprising 2076 patients were eligible for inclusion. Of these, 10 trials (2013 patients) compared tranexamic acid with placebo. Risk of death was significantly reduced in patients who received\ud tranexamic acid compared with those who received placebo (RR 0.59, 95% CI 0.43- 0.82, P = 0.001) with no significant heterogeneity noted among studies (I2 = 0%, P = 0.81). The GRADE assessment rated the quality of the evidence for mortality\ud as moderate due to risk of bias. There were no statistically significant differences between tranexamic acid and placebo for the prevention of re-bleeding, need for surgical interventions, need for blood transfusions or frequency of thromboembolic\ud events.\ud Conclusions: Moderate-quality evidence shows that tranexamic acid is superior to placebo for the reduction in mortality in patients with upper gastrointestinal bleeding. While our findings lend further support to the use of tranexamic acid for treating patients with upper gastrointestinal bleeding, additional higher-quality trials are needed.

Background and Aim Upper gastrointestinal bleeding (UGIB) has a high mortality rate and requires efficient and directed acute management. This project aimed to assess patient outcomes following changes to UGIB management protocols at Northern Hospital, Victoria, Australia. Changes involved streamlining management under a single inpatient unit, earlier endoscopy, blood transfusion thresholds, and risk stratification. Methods This was a cohort study of 400 patients aged ≥18 years admitted to Northern Hospital who underwent endoscopy for acute UGIB. Data of preprotocol changes (Group 1) and prospectively postprotocol changes (Group 2) were collected retrospectively. Primary outcomes were inpatient mortality, rebleeding, radiologic or surgical intervention, and endoscopic reintervention. Secondary outcomes included length of stay (LOS) ≥4 days and blood units transfused. Univariate analyses were conducted comparing groups and associations between variables and outcomes, followed by multivariate analyses for each outcome. Results There was no difference in mortality on multivariate analysis (P = 0.95). Rebleeding reduced by 4% (adjusted odds ratio [AOR] 0.48; P = 0.03), LOS ≥4 days reduced by 15.1% (AOR 0.46; P, The 2017 upgrade of management protocols for acute upper gastrointestinal bleeding at Northern Hospital focused on faster times to endoscopy, reduced blood transfusion thresholds and new risk stratification tools. A review of patient outcomes following these changes demonstrated significant improvements in re‐bleeding rates, length of stay and blood transfusion rates.

INTRODUCTION: With increasing advances in minimally invasive endoscopic therapies and endoscopic resection techniques for luminal disease, there is an increased risk of post-procedure bleeding. This can contribute to significant burden on patient’s quality of life and health resources when reintervention is required. Hemospray (Cook Medical, North Carolina, USA) is a novel haemostatic powder licensed for gastrointestinal bleeding. The aim of this single-arm, prospective, non-randomised multicentre international study is to look at outcomes in patients with upper gastrointestinal bleeds following elective endoscopic therapy treated with Hemospray to achieve haemostasis. METHODS: Data was prospectively collected on the use of Hemospray from 16 centres (January 2016–November 2019). Hemospray was used during the presence of progressive intraprocedural bleeding post-endoscopic therapy as a monotherapy, dual therapy with standard haemostatic techniques or rescue therapy once standard methods had failed. Haemostasis was defined as the cessation of bleeding within 5 min of the application of Hemospray. Re-bleeding was defined as a sustained drop in haemoglobin (>2 g/l), haematemesis or melaena with haemodynamic instability after the index endoscopy. RESULTS: A total of 73 patients were analysed with bleeding post-endoscopic therapy. The median Blatchford score at baseline was five (interquartile range 0–9). The median Rockall score was six (interquartile range 5–7). Immediate haemostasis following the application of Hemospray was achieved in 73/73 (100%) of patients. Two out of 57 (4%) had a re-bleed post-Hemospray, one was following oesophageal endoscopic mucosal resection and the other post-duodenal endoscopic mucosal resection. Both patients had a repeat endoscopy and therapy within 24 h. Re-bleeding data was missing for 16 patients, and mortality data was missing for 14 patients. There were no adverse events recorded in association with the use of Hemospray. CONCLUSION: Hemospray is safe and effective in achieving immediate haemostasis following uncontrolled and progressive intraprocedural blood loss post-endoscopic therapy, with a low re-bleed rate.

We report the case of a 48-year-old woman treated for a gastrointestinal stroma tumor of the duodenum after presenting with upper gastrointestinal bleeding. She was treated with a combination of a radiological and endoscopic approach and minimally invasive surgery. During follow-up, the patient developed a second metachronous duodenal gastrointestinal stroma tumor, distinct from a local recurrence. This tumor was treated with a conservative surgical approach.

Background and aim Antibiotic prophylaxis should be instituted for cirrhotic patients with upper gastrointestinal bleeding (UGIB), but the benefit on compensated patients remains undetermined. We aimed to compare the clinical outcomes between cirrhotic patients without major complications with UGIB with and without antibiotic prophylaxis. Methods We conducted this population-based cohort study by using Taiwanese Longitudinal Health Insurance Database 2000 (LHID2000, between 1997 to 2013), aged 18 years or older with a hospital discharge diagnosis of cirrhosis (n = 64,506), UGIB (n = 7,784), and endoscopic therapy (n = 2,292). After strict exclusions, 1205 patients were enrolled and were divided into antibiotic exposure (n = 558) and non-exposure (n = 647) groups. The outcomes were rebleeding and mortality. Results After completing the analysis adjusted by death, the rebleeding rates within 4 weeks were significantly lower in patients with antibiotic prophylaxis (3.05% versus 6.03%, P = 0.0142) and those with endoscopic therapy (0.72% vs 3.09%, P = 0.0033) but not significant after 3 months and onwards. Male patients aged > 55, high CCI score ≧ 4, and UGIB of variceal etiologies were benefited from rebleeding. The use of antibiotics did not significantly impact 6-week mortality (adjusted hazard ratio: 1.07, 95%CI: 0.41~2.75; P = 0.8943). Old age, multiple comorbidities, and UGIB of variceal etiologies were risk factors of all-cause mortality. Conclusions The current study suggested that cirrhotic patients without major complications who suffered from UGIB were benefited by the use of antibiotics to prevent rebleeding within 4 weeks after endoscopic treatment of UGIB especially for those with age > 55, high CCI score ≧ 4, and UGIB of variceal etiologies.

BACKGROUND: Acute upper gastrointestinal bleeding (UGIB) remains a major cause of hospital admission worldwide. The recent UK National Confidential Enquiry into Patient Outcome and Death (NCEPOD) report on severe gastrointestinal bleeding used the Shock Index to assess bleeding severity and found an association between Shock Index and mortality. However, this has never been prospectively validated as a predictor of outcome in UGIB.AIMS: To compare the Shock Index with existing pre-endoscopic UGIB risk scores in predicting outcomes after UGIB METHODS: In an international, prospective study of 3012 consecutive patients with UGIB, we compared the Shock Index with existing scores including the Glasgow Blatchford score (GBS), admission Rockall score, AIMS65, and the newly described "ABC" score. Pre-determined endpoints were need for major (≥4 units red cells) transfusion, need for endoscopic therapy and 30-day mortality.RESULTS: The Shock Index was inferior to the GBS in predicting need for major transfusion (area under the receiver operator characteristic curve [AUROC] 0.655 vs 0.836, P < 0.001) and need for endotherapy (AUROC 0.606 vs 0.747, P < 0.001). The Shock Index was inferior to all other scores for 30-day mortality: for example, AUROC 0.611 vs 0.863 for ABC score (P < 0.001). Adding the Shock Index to the ABC score did not improve accuracy of the ABC score in predicting mortality (AUROC 0.864 vs 0.863, P = 0.95).CONCLUSION: The Shock Index performed poorly with AUROCs

Background and aim Upper gastrointestinal bleeding (UGIB) is a serious complication of portal hypertension in cirrhotic patients. The objective of this study is to identify the risk factors for morbidity and mortality occurring after an UGIB attack. Methods A total of 1097 UGIB attacks in 690 patients with liver cirrhosis were studied. Their clinical, laboratory, and endoscopic data were reviewed. Results Mean age 53.2 ± 10.6 (20-90) years, 78% men and the main cause of liver disease was hepatitis C (94.9%). Complications occurred after 467 attacks (42.6%): hepatic encephalopathy 31.4%, spontaneous bacterial peritonitis 18%, renal impairment 13.2%, and re-bleeding in 7.8%, while 199 patients (18.1%) died. Complications followed 78.4% of bleeding from gastric varices, 75% of post-interventional ulcers, 10.8% of peptic ulcers, and 5.9% of telangiectasias. By univariate analysis: packed red blood cells units transfused, transaminases, Child-Pugh (CP), model of end-stage liver disease (MELD), and albumin-bilirubin (ALBI) scores, beside the presence of hepatocellular carcinoma (HCC), previous hemorrhage in the previous 6 months, and the source of bleeding, were associated with occurrence of complications. By multivariate analysis, independent predictors of complications were CP, MELD, and ALBI scores (odds ratio, 95% confidence interval: 5.63, 3.55-8.93; 1.15, 1.11-1.19; and 2.11, 1.4-3.19, respectively) beside the presence of HCC (4.89, 2.48-9.64). Mortality predictors were packed red blood cells units transfused (1.11, 1.01-1.24), CP (5.1, 1.42-18.25) MELD (1.27, 1.21-1.32) scores, and presence of HCC (6.62, 2.93-14.95). Conclusion High CP, MELD, and ALBI scores beside the presence of HCC could predict poor outcome of UGIB. In the absence of these risk factors, early discharge could be considered if the source of bleeding is peptic ulcer or telangiectasia.

Background: Endoscopy within 24 hours of admission (early endoscopy) is a quality standard in acute upper gastrointestinal bleeding (AUGIB). We aimed to audit time to endoscopy outcomes and identify factors affecting delayed endoscopy (>24h of admission). Methods: This prospective multicentre audit enrolled patients admitted with AUGIB who underwent inpatient endoscopy between Nov-Dec 2017. Analyses were performed to identify factors associated with delayed endoscopy, and to compare patient outcomes, including length of stay and mortality rates, between early and delayed endoscopy groups. Results: Across 348 patients from 20 centres, the median time to endoscopy was 21.2h (IQR 12.0- 35.7), comprising median admission to referral and referral to endoscopy times of 8.1h (IQR 3.7- 18.1) and 6.7h (IQR 3.0-23.1) respectively. Early endoscopy was achieved in 58.9%, although this varied by centre (range: 31.0% - 87.5%, p=0.002). On multivariable analysis, lower Glasgow-Blatchford score, delayed referral, admissions between 7am-7pm or via the Emergency Department were independent predictors of delayed endoscopy. Early endoscopy was associated with reduced length of stay (median difference 1d; p= 0.004), but not 30-day mortality (p=0.344). Conclusions: The majority of centres did not meet national standards for time to endoscopy. Strategic initiatives involving acute care services may be necessary to improve this outcome.

BACKGROUND Restrictive red blood cell (RBC) transfusion reduces mortality and rebleeding after upper gastrointestinal bleeding (UGIB). However, there is no evidence to guide transfusion strategies in lower gastrointestinal bleeding (LGIB). AIM To assess the association between RBC transfusion strategies and outcomes in patients with LGIB METHODS: This was a post hoc analysis of the UK National Comparative Audit of LGIB and the Use of Blood. The relationships between liberal RBC transfusion and clinical outcomes of rebleeding, mortality and a composite outcome for safe discharge were examined. Transfusion strategy was dichotomised and defined as "liberal" when transfusion was administered for haemoglobin (Hb) ≥80 g/L (or ≥90 g/L in patients with acute coronary syndrome) or major haemorrhage, and "restrictive" otherwise. Multivariable logistic regression models were used to assess the independent association between liberal RBC transfusion and outcomes. RESULTS Of 2528 consecutive patients enrolled from 143 hospitals in the original study, 666 (26.3%) received RBC transfusion (mean age 73.3 ± 16 years, 49% female, initial mean haemoglobin 90 ± 24 g/L, 2.3% had haemodynamic instability). The rebleeding rate in transfused patients was 42.3%. After adjusting for potential confounders, there was no difference between liberal and restrictive RBC transfusion strategies for the odds of rebleeding (OR 0.89, 95% CI 0.6-1.22), in-hospital mortality (OR 0.54, 95% CI 0.3-1.1) or of achieving the composite outcome (OR 0.72, 95% CI 0.5-1.1). CONCLUSION Although these results could be due to residual confounding, they provide an important foundation for the design of randomised trials to evaluate transfusion strategies for LGIB.

GUIDELINE TITLE American College of Gastroenterology: Upper Gastrointestinal and Ulcer Bleeding RELEASE DATE: May 1, 2021 PRIOR VERSION(S): March 1, 2012 DEVELOPER: American College of Gastroenterology Practice Parameters Committee FUNDING SOURCE: American College of Gastroenterology TARGET POPULATION: Adult patients with overt upper gastrointestinal bleeding.

Upper gastrointestinal bleeding is a rare and potentially life-threatening condition in children. Herein, clinical features and risk factors in children with upper gastrointestinal bleeding were analyzed, and a clinical scoring system was constructed to assess severity.This retrospective cohort study involved 224 children hospitalized with upper gastrointestinal bleeding between January 2012 and April 2018. Demographic data, clinical information, and laboratory test results on admission were statistically examined.Out of 224 upper gastrointestinal bleeding cases, 76 were diagnosed as severe and 148 as mild cases according to the rate of blood loss and severity. Severe group was significantly different from mild group in 23 items including age, number of patients aged more than 7 years, and so forth (P 0.01 or P 0.05). Positive detection rate of bleeding etiology was gradually decreased (P 0.01) in relation to delay in timing of endoscopy. Analysis of logistic regression evinced five independent risk factors for severe cases to be associated with poor consciousness, hemoglobin 80 g/L, hemoglobin drop of 20 g/L, hematochezia, and anemic appearance (P 0.01 or P 0.05). Using these five parameters, a number of scoring models were tested. The most predictive resulted in a scoring system constructed with a total of 16 and a cutoff for intervention of 8.Amalgamation of risk factors with the scoring system plays an important role in assessing upper gastrointestinal bleeding severity in children.

BACKGROUND Although most diverticular bleeding resolve spontaneously, up to 30% can bleed torrentially, necessitating angioembolization, endoscopic or surgical intervention. Non-contact endoscopic therapies, such as topical haemostatic powders, do not require precise targeting and are attractive because identification of specific culprit diverticulum is difficult. While their use in non-variceal upper gastrointestinal bleeding is well established, its role in lower gastrointestinal bleeding remains unclear. We used topical Hemospray in a novel setting of severe diverticular bleeding, evaluating its efficacy in achieving haemostasis, reducing re-bleeding and the need for re-intervention. METHODS Consecutive patients from a tertiary colorectal unit who underwent colonoscopy and Hemospray for severe diverticular bleeding from November 2016 to October 2017 were included. Hemospray was endoscopically applied to colonic segments with major stigmata of recent haemorrhage. RESULTS Ten patients had a median time to colonoscopy of 22 h (range: 8-54) from admission. Median of 3.5 units (range: 0-10) of packed cells were transfused pre-endoscopy. All achieved immediate haemostasis without further haemodynamic instability or re-bleeding. No endoscopic, radiological or surgical re-intervention was required. Patients were fit for discharge within a median of 3 days (range: 2-7) following Hemospray. There were no morbidities, mortalities or readmissions for diverticular bleeding after a median follow-up of 9.5 months (range: 3-16). CONCLUSION This feasibility study shows that topical haemostatic powders can offer a safe and effective therapeutic endoscopic option in severe diverticular bleeding with high haemostatic rate. Prospective controlled trials are required to establish its efficacy compared to conventional therapy.

Background The need for a blood transfusion, defined as hemoglobin

Despite the recent advances in endoscopic hemostatic techniques, the management of lower gastrointestinal bleeding could be sometimes challenging. Hemostatic powders such as Hemospray, EndoClot, and Ankaferd Blood Stopper have found their way into digestive endoscopy and are licenced in many countries especially for use in upper gastrointestinal bleeding. We reviewed the literature on the use of these hemostatic powders in different situations in lower gastrointestinal bleeding and looked at the success rate and rebleeding rate. Most of the data are derived from case reports, retrospective and prospective case series with absence of any randomized controlled trials. Hemostatic powders were used as primary or salvage therapy to control bleeding from polypectomy site, colonic tumors, diverticula, arteriovenous malformations, radiation proctitis, ischemic colitis, and surgical intestinal anastomosis. The rate of immediate control of bleeding is in the range of 88-100% with a recurrence rate of 3-13% except for radiation proctitis bleeding where rebleeding rate can be as high as 77%. Although there are many advantages for the use of local hemostatic agents in lower gastrointestinal bleeding, future randomized controlled trials comparing them with conventional methods are needed.

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

A 59‐year‐old obese Japanese man with poorly controlled type 2 diabetes mellitus presented with severe heartburn for 3 days after inguinal cellulitis and exacerbated glycemic control, without any signs of upper gastrointestinal bleeding. The patient had a high plasma glucose level (34.0 mmol/L) and was dehydrated. Emergent esophagogastroduodenoscopy showed black discoloration predominantly affecting the lower esophagus; thus, acute esophageal necrosis (AEN) was diagnosed. This black discoloration was not present on esophagogastroduodenoscopy 20 days prior to presentation, and disappeared 6 days after conservative treatment. To conclude, acute esophageal necrosis should be considered if a patient in marked hyperglycemic status presents with unendurable heartburn, even when upper gastrointestinal bleeding is not observed or recent esophagogastroduodenoscopy was unremarkable., A 59‐year‐old obese Japanese man with poorly controlled type 2 diabetes mellitus presented with severe heartburn after inguinal cellulitis and exacerbated glycemic control. Emergent esophagogastroduodenoscopy showed acute esophageal necrosis, although signs of upper gastrointestinal bleeding were absent and a recent esophagogastroduodenoscopy was unremarkable.

Transfusion triggers and parameters to consider in the decision to transfuse depend on the setting. In cases of massive bleeding, transfusion decision is made on haemodynamic parameters, vital signs and when possible on bleeding volume estimation. In anaemic haemodynamically stable patients, haemoglobin remains the primary trigger for transfusion. In the less severe or in the youngest critically ill patients, transfusion for a haemoglobin threshold of 7 g/dl has been shown to be associated with higher survival in comparison with a haemoglobin threshold of 10 g/dl. This lower threshold of 7 g/dl appears to be also safe in patients with upper gastrointestinal bleeding. In patients with acute ischaemic heart disease, where anaemia may worsen myocardial ischaemia, pathophysiology and findings from large observational studies support the benefit of a higher haemoglobin threshold (between 9 and 10 g/dl). Elderly and cardiovascular patients should be monitored for cardiac tolerance of anaemia and transfused accordingly. In haematology–oncology patients and in neuro critically ill patients, the optimal strategy for red blood cell (RBC) transfusion remains unknown. Transfusion practices have shifted from liberal towards restrictive strategy, making the monitoring of anaemia tolerance an important element in the decision to transfuse. Substantial comorbidities and conditions that influence anaemia tolerance should be integrated into clinicians’ transfusion decision-making process. Research evaluating the benefit to consider additional triggers in the decision to transfuse RBC in critically ill patients is warranted.

Gastrointestinal bleeding is a common medical and surgical emergency and is the second most common indication for red blood cell (RBC) transfusion in the UK. Most transfusion guidelines recommend the use of restrictive blood transfusion in stable gastrointestinal bleeding. This review explores the evidence supporting this practice, including whether it is safe in lower as well as upper gastrointestinal bleeding, and the risks of restrictive transfusion in patients with cardiovascular disease. There is a lack of evidence supporting the use of platelet and fresh frozen plasma transfusion in gastrointestinal bleeding. The aim of this review is to serve as a practical guide to transfusion in stable gastrointestinal bleeding.

BACKGROUND: Observational studies have consistently shown an increased risk of upper gastrointestinal bleeding in users of selective serotonin receptor inhibitors (SSRIs), probably explained by their inhibition of platelet aggregation. Therefore, treatment with SSRIs is often temporarily withheld in patients with peptic ulcer bleeding. However, abrupt discontinuation of SSRIs is associated with development of withdrawal symptoms in one-third of patients. Further data are needed to clarify whether treatment with SSRIs is associated with poor outcomes, which would support temporary discontinuation of treatment.AIM: To identify if treatment with SSRIs is associated with increased risk of: (1) endoscopy-refractory bleeding, (2) rebleeding or (3) 30-day mortality due to peptic ulcer bleeding.METHODS: A nationwide cohort study. Analyses were performed on prospectively collected data on consecutive patients admitted to hospital with peptic ulcer bleeding in Denmark in the period 2006-2014. Logistic regression analyses were used to investigate the association between treatment with SSRIs and outcome following adjustment for pre-defined confounders. Sensitivity and subgroup analyses were performed to evaluate the validity of the findings.RESULTS: A total of 14 343 patients were included. Following adjustment, treatment with SSRIs was not associated with increased risk of endoscopy-refractory bleeding (odds ratio [OR] [95% Confidence Interval (CI)]: 1.03 [0.79-1.33]), rebleeding (OR [95% CI]: 0.96 [0.83-1.11]) or 30-day mortality (OR [95% CI]: 1.01 [0.85-1.19]. These findings were supported by sensitivity and subgroup analyses.CONCLUSIONS: According to our data, treatment with SSRIs does not influence the risk of endoscopy-refractory bleeding, rebleeding or 30-day mortality in peptic ulcer bleeding.

OBJECTIVE To analyze the clinical characteristics, outcomes and prognostic factors in elderly patients (aged 75 years and elder) with acute nonvariceal upper gastrointestinal bleeding (UGIB). METHODS Consecutive patients admitted with acute nonvariceal UGIB who underwent upper gastrointestinal endoscopy were prospectively recruited and subdivided into two age-based groups, elderly (aged ≥75 years) and younger patients (

Background and Aim Upper gastrointestinal bleeding (UGIB) is a threatening condition leading to urgent hospitalization. This study aims to investigate etiology and outcome in UGIB patients in Iran. Methods Medical records of GIB patients admitted to Alzahra referral hospital (in Isfahan) during 2010–2015 were retrospectively reviewed for demographic data, comorbidities, history of smoking and taking non-steroidal anti-inflammatory drugs (NSAIDs), presenting symptoms, endoscopic findings, therapeutic endoscopy, blood products’ infusion, surgical intervention and mortality. Results A total of 4747 patients were enrolled in the study (69.2% male, mean age = 55.46 ± 21.98 years). Hematemesis was the most frequent presenting symptom (63.5%). Peptic ulcer (duodenal ulcer in most cases) was seen as the main reason for UGIB (42.4%). Rebleeding (present in 16.5% of patients), was found to be more frequent in patients with older age, presenting sign of hematochezia and hypotension, history of taking NSAIDs and smoking, presence of comorbidities, history of bleeding due to UGI tract neoplasm and esophageal varices, history of needing blood products’ infusion, and history of therapeutic endoscopy or surgical intervention (P-value

Aortoduodenal fistula is a rare cause of life‐threatening upper gastrointestinal bleeding. Accurate diagnosis is essential to initiate definitive treatment because endoscopic hemostasis, which is the usual initial intervention for upper gastrointestinal bleeding, may be ineffective. This case underscores timely intervention using endovascular treatment for achieving hemostasis in aortoduodenal fistula.

Background Epistaxis is a common condition that can sometimes be overlooked. It usually presents with obvious symptoms but could also present as hematemesis and melena. Case Presentation A 78‐year‐old man presented to our emergency department with melena and shock. Initial endoscopy revealed a bleeding gastric ulcer. However, he had recurrent episodes of hematemesis and melena following coagulation therapy, and a repeat esophagogastroduodenoscopy could not identify the source of bleeding for more than 1 week. Epistaxis from nasal polyps was identified as the cause of hemorrhagic shock. Posterior nasal packing was carried out with Foley catheters, and an endoscopic sinus surgery was finally performed. Conclusion We report a case of epistaxis that caused hematemesis and melena following gastrointestinal bleeding. The diagnosis of epistaxis might have been delayed due to anchoring bias. Clinicians should be aware that epistaxis can mimic upper gastrointestinal bleeding and remember this important differential diagnosis., Intraoperative findings of a 78‐year‐old man who underwent endoscopic sinus surgery for hemostasis of epistaxis. Bleeding nasal polyps were seen in the right superior nasal meatus. The nasal mucosa easily bled. Argon plasma coagulation was carried out to achieve hemostasis.

In patients with anemia, transfusion of red blood cells (RBCs) can save lives and improve quality of life. The choice to transfuse should be cautiously made owing to risks of transfusion, economic costs, and limitations on the blood supply. Until the 1980s, the decision for RBC transfusion was guided by Hb threshold, with the aim of maintaining the patient's blood Hb level over 100 grams per liter. Since then, multiple randomized controlled trials and key systematic reviews have provided evidence-based guidelines as to appropriate transfusion thresholds in a number of clinical settings. Here, we aimed to address the outcome of defining different anemia criteria in specific clinical populations exclusively on the basis of the need for RBC transfusion based on Hb concentration. We focused on the patient populations, where there were the most available data on differing transfusion thresholds, which looked at transfusing to a higher or liberal transfusion threshold in comparison with a lower or restrictive transfusion threshold. These included patients in intensive care with or without septic shock, hip fracture surgery, cardiovascular surgery, and upper gastrointestinal bleeding, the pediatric population, and also those with malaria, by reviewing key randomized controlled trials and systematic reviews. Twenty-four randomized controlled studies and 12 systematic reviews have been included, and these are discussed below.
