Examining the Frequency of Second Endoscopy and Its Effect on Patient Outcomes With Upper Gastrointestinal Bleeding in Southeast of Iran.

This study investigated the frequency and impact of repeat endoscopy in patients with acute upper gastrointestinal bleeding (AUGIB) in a referral hospital in Southeast Iran. A cross-sectional descriptive-analytical study was conducted on the records of 190 patients who underwent endoscopy for AUGIB in 2019. The study compared the demographic and clinical characteristics, outcomes, and treatments of patients who had a second endoscopy (n=64) with those who did not (n=126). The data were analyzed with SPSS software, and a P value less than 0.05 was considered significant. The results showed that repeat endoscopy was not significantly associated with age, gender, initial symptoms, bleeding site, first endoscopy time, or disease outcome. However, repeat endoscopy was significantly associated with higher bleeding severity, different wound types, different bleeding causes, longer hospital stay, and different treatments in the first endoscopy. The main reasons for repeat endoscopy were poor visibility and recurrent bleeding. The majority of repeat endoscopies were performed within 2 days of the first one. Most patients who had a second endoscopy did not receive any treatment, and those who did received combined thermal and epinephrine injections. The study concluded that routine second endoscopy is not necessary for all patients with AUGIB, but it may be beneficial for some cases. Further research is needed to clarify the indications and timing of repeat endoscopy in AUGIB.

Real-World Bleeding Risk of Anticoagulant and Nonsteroidal Anti-inflammatory Drugs Combotherapy versus Anticoagulant Monotherapy.

The incidence of acute gastrointestinal bleeding (GIB) increases with the utilization of anticoagulant and nonsteroidal anti-inflammatory drugs (NSAIDs). This study aimed to compare the risk of GIB between anticoagulant and NSAIDs combotherapy and anticoagulant monotherapy in real-world practice. We investigated the relative risk of GIB in individuals newly prescribed anticoagulant and NSAIDs combination therapy and that in individuals newly prescribed anticoagulant monotherapy at three hospitals using "common data model." Cox proportional hazard models and Kaplan-Meier estimation were employed for risk comparison after propensity score matching. A comprehensive analysis of 2,951 matched pairs showed that patients who received anticoagulant and NSAIDs combousers exhibited a significantly higher risk of GIB than those who received anticoagulant monousers (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.30 to 2.12; p<0.001). The risk of GIB associated with anticoagulant and NSAIDs combination therapy was also significantly higher than that associated with anticoagulant monotherapy in patients aged >65 years (HR, 1.53; 95% CI, 1.15 to 2.03; p=0.003) and >75 years (HR, 1.89; 95% CI, 1.23 to 2.90; p=0.003). We also found that the risk of GIB was significantly higher in the patients who received anticoagulant and NSAIDs combousers than that in patients who received anticoagulant monousers in both male (p=0.016) and female cohorts (p=0.010). The risk of GIB is significantly higher in patients who receive anticoagulant and NSAIDs combotherapy than that in patients who receive anticoagulant monotherapy. In addition, the risk of GIB associated with anticoagulant and NSAIDs combotherapy was much higher in individuals aged >75 years. Therefore, physicians should be more aware of pay more attention to the risk of GIB when they prescribe anticoagulant and NSAIDs.

Risk factors and management of gastrointestinal bleeding in patients with or without antiplatelet and anticoagulation therapy: a multicenter real-world prospective study

BackgroundAntiplatelet and anticoagulation drugs complicate acute gastrointestinal bleeding (GIB) patients. Limited data about the risk factors and patient management has been presented. This study explored the association between previous antiplatelet or anticoagulant drug usage and clinical outcomes in GIB patients to improve awareness further and optimize treatment.MethodsWe conducted a multicenter, non-interventional, real-world prospective study in 106 hospitals in 23 provinces in China. GIB patients confirmed in the emergency department were included and were grouped according to previous drug histories. Univariate analysis, multivariate logistic regression, and multivariate stratification models were performed separately to investigate the associations.ResultsA total of 2299 patients (57.23 ± 17.21 years old, 68.3% male) were included, of whom 20.1% and 2.9% received antiplatelet and anticoagulation therapy, respectively. The all-cause 28-day mortality rates in patients without antiplatelet or anticoagulants, patients undergoing antiplatelet treatment, and patients with anticoagulation therapy were 2.8%, 4.6%, and 10.5%, respectively. After adjusting for confounding factors, both antiplatelet [odd ratio (OR), 2.92; 95% confidence interval (CI), 1.48–5.76; p = 0.002] and anticoagulation therapy (OR, 8.87; 95% CI, 3.02–26.02; p < 0.001) were associated with higher 28-day mortality. In the subgroup analysis, blood transfusion, especially red blood cell transfusion, in patients undergoing antiplatelet and anticoagulation therapy was associated with a decreased death risk.ConclusionWe confirmed an association between concurrent antiplatelet or anticoagulation therapy in GIB patients and elevated 28-day mortality. Blood transfusions could improve poor outcomes in such patients.

Acute upper and lower gastrointestinal bleeding management in older people taking or not taking anticoagulants: a literature review

Acute upper and lower gastrointestinal (GI) bleeding may be a potentially life-threatening event that requires prompt recognition and an early effective management, being responsible for a considerable number of hospital admissions. Methods. We perform a clinical review to summarize the recent international guidelines, helping the physician in clinical practice. Older people are a vulnerable subgroup of patients more prone to developing GI bleeding because of several comorbidities and polypharmacy, especially related to an increased use of antiplatelet and anticoagulant drugs. In addition, older patients may have higher peri-procedural risk that should be evaluated. The recent introduction of reversal strategies may help the management of GI bleeding in this subgroup of patients. In this review, we aimed to (1) summarize the epidemiology and risk factors for upper and lower GI bleeding, (2) describe treatment options with a focus on pharmacodynamics and pharmacokinetics of different proton pump inhibitors, and (3) provide an overview of the clinical management with flowcharts for risk stratification and treatment. In conclusion, GI is common in older patients and an early effective management may be helpful in the reduction of several complications.

Efficacy of ferric carboxymaltose on haemoglobin response among older patients with gastrointestinal bleeding: a randomised clinical trial.

Acute gastrointestinal bleeding (AGIB) is common in older patients but the use of iron in this context remains understudied. This study aimed to evaluate prospectively the efficacy of ferric carboxymaltose to treat anaemia in older patients after AGIB. This randomised double-blinded placebo-controlled clinical trial was conducted in 10 French centres. Eligible patients were 65years or more, had controlled upper or lower gastrointestinal bleeding and a haemoglobin level of 9-11g/dl. Patients were randomly assigned, in a 1:1 ratio, to receive either one intravenous iron injection of ferric carboxymaltose or one injection of saline solution. The primary endpoint was the difference in haemoglobin level between day 0 and day 42. Secondary endpoints were treatment-emergent adverse events, serious adverse events, rehospitalisation and improvement of quality of life (QOL) at day 180. From January 2013 to January 2017, 59 patients were included. The median age of patients was 81.9 [75.8, 87.3] years. At day 42, a significant difference in haemoglobin level increase was observed (2.49g/dl in the ferric carboxymaltose group vs. 1.56g/dl in the placebo group, P = 0.02). At day 180, QOL, measured on European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30, improved by 10.5 points in the ferric carboxymaltose group and by 8.2 points in the placebo group (P = 0.56). Rates of adverse events and rehospitalisation were similar in the two groups. Intravenous iron seems safe and effective to treat anaemia in older patients after AGIB and should be considered as a standard-of-care treatment. ClinicalTrials.gov (NCT01690585).

Clinical data analysis of 117 patients with ruptured abdominal aortic aneurysm

Objective: To examine the perioperative clinical features and prognosis of patients with ruptured abdominal aortic aneurysms (rAAA) who received surgical repair. Methods: The clinical data of rAAA patients who underwent surgical repair and were admitted to the Surgical Intensive Care Unit of Beijing Anzhen Hospital, Capital Medical University from August 2005 to November 2020 were retrospectively analyzed, including the general clinical features, surgical mode, intraoperative conditions, postoperative complications, and fatality rate. Results: There were 117 patients with rAAA, with a median age of 68 (62,77) years, including 93 men (79.5%) and 24 women (20.5%). The main clinical manifestation was abdominal pain (n=115, 98.3%). Among them, 65 (55.6%) patients underwent endovascular aneurysm repair (EVAR), while 52 (44.4%) underwent open surgical repair (OSR). The common postoperative complications include acute gastrointestinal dysfunction (n=116, 99.1%), shock (n=89, 76.1%), acute respiratory distress syndrome (n=85, 72.6%), pancreatic injury (n=56, 47.9%), coagulation dysfunction (n=55, 47.0%), disseminated intravascular coagulation (n=46, 39.3%), acute kidney injury (n=39, 33.3%), infection/sepsis (n=28, 23.9%), gastrointestinal bleeding (n=17, 14.5%), and abdominal compartment syndrome (n=12, 10.3%). The overall postoperative in-hospital fatality rate was 10.3% (12/117). Preoperative use of vasopressors and inotropes, retroperitoneal hematoma, and postoperative abdominal compartment syndrome, gastrointestinal hemorrhage, acute kidney injury, and diffuse intravascular coagulation significantly increased the fatality rate [5/11, 6/24, 5/16, 6/12, 6/17, 23.1%(9/39), 19.6%(9/46), respectively]. Conclusion: The postoperative mortality of rAAA patients is still high in the era of EVAR, especially in patients with preoperative existence of shock and retroperitoneal hematoma, and with postoperative abdominal compartment syndrome, coagulation dysfunction, and acute kidney injury. It is necessary to strengthen perioperative monitoring and management of these patients to reduce the fatality rate.

Recurrent gastric antral vascular ectasia: a single center experience.

Gastric antral vascular ectasia (GAVE) is a rare cause of chronic or acute gastrointestinal bleeding. This condition accounts for ∼4% of upper gastrointestinal bleeding cases. This disease is often associated with systemic diseases, such as liver cirrhosis, chronic kidney failure, autoimmune conditions, diabetes mellitus, hypothyroidism, and cardiovascular diseases. However, its etiopathogenesis remains controversial. We retrospectively reviewed the cases of GAVE treated at our digestive surgery unit. A total of nine patients were identified with a male/female ratio of 1.25:1 and an average age of 75.51 years (SD ± 9.85). All patients underwent endoscopic argon plasma coagulation (APC) treatment. At the time of the review, data on eight patients were available after 36 months of follow-up. APC appears to be safe and effective for hemostasis of bleeding vascular ectasia. Only one (11.1%) patient required surgical intervention due to hemodynamic instability after multiple unsuccessful endoscopic treatments. No intraoperative and postoperative complication or bleeding relapse was experienced. Based on our findings, we concluded that endoscopic APC is technically simple, but requires multiple re-interventions due to the incidence of relapses. Furthermore, larger randomized studies should be conducted to assess the role of elective surgery as the first intervention in stable patients with severe pathology and the timing of surgery after failed endoscopic treatment.

Upper gastrointestinal bleeding: Diagnosis of Helicobacter pylori infection-Descriptive study.

The presence of blood in the stomach has been thought to affect the performance of diagnostic tests used in detecting Helicobacter pylori (H. pylori) in the stomach. This study evaluates the effect of upper gastrointestinal bleeding on the efficacy of a rapid urease test (RUT) and compares the results with the pathologic method. In this descriptive study, 100 patients presented with upper gastrointestinal bleeding, confirmed from endoscopy, referred to Shahid Rahimi Hospital in Khorramabad were enrolled. Antral biopsy was performed in all the patients and the samples were extracted for histopathology and RUT. A questionnaire was used to collect rapid urease test outcomes and associated parameters (antibiotic, bismuth, and proton pump inhibitors), histology and demographic data. Histopathology was used as the gold standard for diagnosis of H. pylori. Of the 52 patients who were reported positive for H. pylori in pathology, 36 had RUT-positive H. pylori, sensitivity 69.2%, and of 48 patients whose pathology was negative, 25 had negative RUT, specificity 52.1%. Of 59 RUT, 36 had positive pathology, positive predictive value was 61% and from 41 with negative RUT, 25 had negative pathology, negative predictive value was 61%. The prevalence of H. pylori infection was significantly associated with the age of 50 years and above, p = 0.042, and previous history of bleeding, p = 0.019. Gastrointestinal bleeding can reduce the sensitivity of RUT. The negative results of these tests in acute upper gastrointestinal bleeding should therefore be interpreted carefully.

Intravenous metoclopramide for increasing endoscopic mucosal visualization in patients with acute upper gastrointestinal bleeding: a multicenter, randomized, double-blind, controlled trial

Acute upper gastrointestinal hemorrhage (UGIH) is the most common emergency condition that requires rapid endoscopic treatment. This study aimed to evaluate the effects of pre-endoscopic intravenous metoclopramide on endoscopic mucosal visualization (EMV) in patients with acute UGIH. This was a multicenter, randomized, double-blind controlled trial of participants diagnosed with acute UGIH. All participants underwent esophagogastroduodenoscopy within 24 h. Participants were assigned to either the metoclopramide or placebo group. Modified Avgerinos scores were evaluated during endoscopy. In total, 284 out of 300 patients completed the per-protocol procedure. The mean age was 62.8 ± 14.3 years, and 67.6% were men. Metoclopramide group achieved a higher total EMV and gastric body EMV score than the other group (7.34 ± 1.1 vs 6.94 ± 1.6; P = 0.017 and 1.80 ± 0.4 vs 1.64 ± 0.6; P = 0.006, respectively). Success in identifying lesions was not different between the groups (96.5% in metoclopramide and 93.6% in placebo group; P = 0.26). In the metoclopramide group, those with active variceal bleeding compared with the control group demonstrated substantial improvements in gastric EMV (1.83 ± 0.4 vs 1.28 ± 0.8, P = 0.004), antral EMV (1.96 ± 0.2 vs 1.56 ± 0.6, P = 0.003), and total EMV score (7.48 ± 1.1 vs 6.2 ± 2.3, P = 0.02). Pre-endoscopic intravenous metoclopramide improved the quality of EMV in variceal etiologies of UGIH, which was especially prominent in those who had signs of active bleeding based on nasogastric tube assessment.Trial Registration: Trial was registered in Clinical Trials: TCTR 20210708004 (08/07/2021).

Assessment of Severity Level of Gastrointestinal Bleeding Patients with Associated Cardiology Disease with Different Scales

The purpose of this study is to select and compare a range of rating scales to assess the clinical status of high-risk patients with gastrointestinal bleeding (GIB). It was based on the evaluation of the severity of the disease by applying different integral scales in patients with heart disease and developing acute GIB. We evaluated the condition of the patients with Forest (F), Rockall and Glasgow-Blatkford integral scales. We achieved endoscopic homeostasis in 11.81% of patients. We managed to cure 69.15% of patients with conservative treatment and 19.04% with surgical treatment. According to the results of the Rockall scale, 23.63% of high-risk patients and 31.73% of higher-risk patients (total 55.36%) were. However, 19.04% of patients with a severity score above 6 required surgery. Based on these results, we believe that in patients with heart disease and GIB, the severity of the patient’s condition and the Glasgow-Blatkford integral scale are more appropriate in choosing the treatment protocol to be selected.

External Validation of the Oakland Score for Acute Lower Gastrointestinal Bleeding.

Introduction Acute lower gastrointestinal bleeding (LGIB) presents challenges in emergency settings, with incidence influenced by demographic shifts and anticoagulant usage. The Oakland score aids in risk stratification for safe discharge based on clinical and laboratory parameters. However, external validation remains limited. Methods This study validated the Oakland score in a French cohort of patients with acute LGIB and assessed the discriminatory value of the score using the area under the curve (AUC) and then its sensitivity and specificity. Results A retrospective examination of 343 patient records that satisfied the inclusion criteria showed a median score of 14 points and good discriminatory capacity (area under the receiver operating characteristic (AUROC) curve: 0.83). There was low sensitivity (20.9%) for safe discharge but good specificity (98.5%) when using an 8-point threshold. With a 9-point threshold, the sensitivity was increased to 36.5%, while the specificity remained at 95%. Conclusion Identifying low-risk LGIB patients is accomplished without sacrificing sensitivity by increasing the Oakland score threshold to 9 points. This modification improves patient safety and resource allocation in the emergency room and has been verified by other large series. For wider implementation, additional validation and long-term outcome evaluations are required.

The impact of early gastroscopy examination on cardiovascular event-related indices in elderly patients with acute upper gastrointestinal bleeding.

To observe the effects of early gastroscopy examination on cardiovascular event-related indicators such as heart rate (HR), blood pressure, and electrocardiogram (ECG) in elderly patients with acute upper gastrointestinal bleeding. Sixty patients with upper gastrointestinal bleeding admitted from July 2022 to December 2022 were selected. Patients with relevant contraindications were excluded. All patients underwent early gastroscopy examination. Among them, 30 patients were aged 60 or above (elderly group) and 30 patients were aged below 60 (non-elderly group). Dynamic blood pressure and ECG recordings were obtained before, during, and after gastroscopy examination to assess changes in HR, blood pressure, and ECG. The HR and blood pressure levels of the elderly group were significantly lower than those of the non-elderly group before, during, and after gastroscopy examination (P < .05). In the elderly group, blood pressure and HR were higher during gastroscopy examination compared to before, but lower than during the examination afterward, with statistically significant differences (P < .05). The diastolic blood pressure was lower after the examination compared to before, with statistical significance, while the systolic blood pressure was lower, and the HR was higher after the examination, but without statistical significance (P > .05). In the non-elderly group, systolic blood pressure and HR were higher during gastroscopy examination compared to before, with statistically significant differences (P < .05), while diastolic blood pressure was higher but without statistical significance (P > .05). Blood pressure and HR were lower after the examination compared to during, with statistically significant differences (P < .05). The occurrence rates of ECG changes were 70% in the elderly group and 30% in the non-elderly group, with a statistically significant difference (χ2 = 5.45, P = .02 < .05). Early gastroscopy examination in elderly patients with gastrointestinal bleeding did not result in severe cardiovascular adverse events and was relatively safe. However, special attention should be given to the occurrence of cardiac arrhythmias.

Endovascular management of a ruptured hepatic artery pseudoaneurysm after liver transplantation presenting as hemobilia

Vascular and biliary complications can still occur among liver transplants despite advances in surgical technique and immunosuppression. Rupture of a hepatic artery pseudoaneurysm is a rare but lethal complication after liver transplantation and often manifests as acute gastrointestinal bleeding. It occurs in < 3% of cases with an associated mortality as high as 50% especially if diagnosed late. A high index of suspicion may decrease consequent morbidities and potential graft loss. Infection and type of biliary anastomosis are commonly identified risk factors in the development of a pseudoaneurysm. Angiography usually identifies the location which is commonly at the site of anastomosis. Frequent management options include surgical revascularization requiring re-operation or endovascular intervention with the use of coils and stents. No consensus yet as to the standard treatment has been established. We present a case of a 40-year-old male having a ruptured hepatic artery pseudoaneurysm with an arteriobiliary fistula after performing a deceased donor liver transplant managed with endovascular placement of a stent. Patient remains asymptomatic with patent hepatic artery after 6 months of follow-up.

Diagnosis value of the blood urea nitrogen to creatinine ratio in determining the need for intervention of acute upper gastrointestinal bleeding.

The blood urea nitrogen (BUN) to creatinine (Cr) ratio (BUN/Cr ratio) may be used to evaluate the need for intervention of acute upper gastrointestinal bleeding (AUGIB). This study aimed to explore the predictive value of the BUN/Cr ratio in the need for intervention of AUGIB. This retrospective observational study included patients with AUGIB in the hospital's emergency department between August 2019 and May 2023. The patients were grouped according to whether they underwent an intervention for AUGIB. Patients treated between August 2019 and May 2022 were selected as the training set and the others as the validation set. A total of 466 patients (328 males, 138 females) with AUGIB were enrolled in the intervention group (n=167) and the no-intervention group (n=299). In the training set, multivariable logistic regression showed that the BUN/Cr ratio (OR: 1.013, 95%CI: 1.003-1.023, P=0.009), hemoglobin (OR: 0.989, 95%CI: 0.981-0.997, P=0.010), and a previous history of esophageal variceal bleeding (OR: 6.898, 95%CI: 3.989-11.929, P<0.001) were independently associated with intervention for AUGIB. The area under receiver operating characteristic curve of BUN/Cr ratio and the prediction model based on logistic regression to predict the need for intervention of AUGIB were 0.604 (95%CI: 0.544-0.664) and 0.759 (95%CI: 0.706-0.812) in the training set and 0.634 (95%CI: 0.529, 0.740) and 0.708 (95% CI: 0.609, 0.806) in the validation set, respectively. The BUN/Cr ratio was associated with the need for AUGIB intervention. Combining it with other parameters might improve its diagnostic value to predict the need for intervention of AUGIB.

Clinical characteristics of acute non-varicose upper gastrointestinal bleeding and the effect of endoscopic hemostasis.

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) constitutes a prevalent emergency within Gastroenterology, encompassing 80%-90% of all gastrointestinal hemorrhage incidents. This condition is distinguished by its abrupt onset, swift progression, and notably elevated mortality rate. To gather clinical data from patients with ANVUGIB at our hospital in order to elucidate the clinical characteristics specific to our institution and analyze the therapeutic effectiveness of endoscopic hemostasis. We retrospectively retrieved the records of 532 patients diagnosed with ANVUGIB by endoscopy at our hospital between March 2021 and March 2023, utilizing our medical record system. Data pertaining to general patient information, etiological factors, disease outcomes, and other relevant variables were meticulously collected and analyzed. Among the 532 patients diagnosed with ANVUGIB, the male-to-female ratio was 2.91:1, with a higher prevalence among males. Notably, 43.6% of patients presented with black stool as their primary complaint, while 27.4% had hematemesis as their initial symptom. Upon admission, 17% of patients exhibited both hematemesis and black stool, while most ANVUGIB patients primarily complained of overt gastrointestinal bleeding. Urgent routine blood examinations at admission revealed that 75.8% of patients had anemia, with 63.4% experiencing moderate to severe anemia, and 1.5% having extremely severe anemia (hemoglobin < 30 g/L). With regard to etiology, 53.2% of patients experienced bleeding without a definitive trigger, 24.2% had a history of using gastric mucosa-irritating medications, 24.2% developed bleeding after alcohol consumption, 2.8% attributed it to improper diet, 1.7% to emotional excitement, and 2.3% to fatigue preceding the bleeding episode. Drug-induced ANVUGIB was more prevalent in the elderly than middle-aged and young individuals, while bleeding due to alcohol consumption showed the opposite trend. Additionally, diet-related bleeding was more common among the young age group compared to the middle-aged group. Gastrointestinal endoscopy identified peptic ulcers as the most frequent cause of ANVUGIB (73.3%), followed by gastrointestinal malignancies (10.9%), acute gastric mucous lesions (9.8%), and androgenic upper gastrointestinal bleeding (1.5%) among inpatients with ANVUGIB. Of the 532 patients with gastrointestinal bleeding, 68 underwent endoscopic hemostasis, resulting in an endoscopic treatment rate of 12.8%, with a high immediate hemostasis success rate of 94.1%. ANVUGIB patients exhibit diverse characteristics across different age groups, and endoscopic hemostatic treatments have demonstrated remarkable efficacy.

Review article: Upper gastrointestinal bleeding - review of current evidence and implications for management.

Acute upper gastrointestinal bleeding (UGIB) is a common emergency requiring hospital-based care. Advances in care across pre-endoscopic, endoscopic and post-endoscopic phases have led to improvements in clinical outcomes. To provide a detailed, evidence-based update on major aspects of care across pre-endoscopic, endoscopic and post-endoscopic phases. We performed a structured bibliographic database search for each topic. If a recent high-quality meta-analysis was not available, we performed a meta-analysis with random effects methods and odds ratios with 95% confidence intervals. Pre-endoscopic management of UGIB includes risk stratification, a restrictive red blood cell transfusion policy unless the patient has cardiovascular disease, and pharmacologic therapy with erythromycin and a proton pump inhibitor. Patients with cirrhosis should be treated with prophylactic antibiotics and vasoactive medications. Tranexamic acid should not be used. Endoscopic management of UGIB depends on the aetiology. For peptic ulcer disease (PUD) with high-risk stigmata, endoscopic therapy, including over-the-scope clips (OTSCs) and TC-325 powder spray, should be performed. For variceal bleeding, treatment should be customised by severity and anatomic location. Post-endoscopic management includes early enteral feeding for all UGIB patients. For high-risk PUD, PPI should be continued for 72 h, and rebleeding should initially be evaluated with a repeat endoscopy. For variceal bleeding, high-risk patients or those with further bleeding, a transjugular intrahepatic portosystemic shunt can be considered. Management of acute UGIB should include treatment plans for pre-endoscopic, endoscopic and post-endoscopic phases of care, and customise treatment decisions based on aetiology and severity of bleeding.

Preliminary report on embolization with quick-soluble gelatin sponge particles for angiographically negative acute gastrointestinal bleeding

Prophylactic embolization is usually performed using gelatin sponge particles, which are absorbed within several weeks, for managing angiographically negative gastrointestinal bleeding. This study aimed to evaluate the safety and effectiveness of transcatheter arterial embolization (TAE) with quick-soluble gelatin sponge particles (QS-GSP) that dissolve in less than 4 h for treating angiographically negative gastrointestinal bleeding. We included ten patients (M:F = 7:3; mean age, 64.3 years) who underwent prophylactic TAE with QS-GSP for angiographically negative acute gastrointestinal bleeding between 2021 and 2023. The technical success rate of TAE, clinical outcomes focusing on rebleeding, and procedure-related complications were evaluated. The embolized arteries were the gastroduodenal (n = 3), jejunal (n = 4), and ileal (n = 3) arteries. QS-GSP (150–350 µm or 350–560 µm) were used alone (n = 8) or in combination with a coil (n = 1). A 100% technical success rate was accomplished. In 1 patient (10%), rebleeding occurred 2 days after prophylactic TAE of the gastroduodenal artery, and this was managed by repeat TAE. There were no procedure-related complications. The use of QS-GSP for prophylactic TAE appears to be safe and effective for controlling bleeding among patients with angiographically negative gastrointestinal bleeding. There were no cases of related ischemic complications of the embolized bowels likely attributable to recanalization of the affected arteries following biodegradation of QS-GSP.

Mortality for Time-Sensitive Conditions at Urban vs Rural Hospitals During the COVID-19 Pandemic

COVID-19 pandemic-related disruptions to the health care system may have resulted in increased mortality for patients with time-sensitive conditions. To examine whether in-hospital mortality in hospitalizations not related to COVID-19 (non-COVID-19 stays) for time-sensitive conditions changed during the pandemic and how it varied by hospital urban vs rural location. This cohort study was an interrupted time-series analysis to assess in-hospital mortality during the COVID-19 pandemic (March 8, 2020, to December 31, 2021) compared with the prepandemic period (January 1, 2017, to March 7, 2020) overall, by month, and by community COVID-19 transmission level for adult discharges from 3813 US hospitals in the State Inpatient Databases for the Healthcare Cost and Utilization Project. The COVID-19 pandemic. The main outcome measure was in-hospital mortality among non-COVID-19 stays for 6 time-sensitive medical conditions: acute myocardial infarction, hip fracture, gastrointestinal hemorrhage, pneumonia, sepsis, and stroke. Entropy weights were used to align patient characteristics in the 2 time periods by age, sex, and comorbidities. There were 18 601 925 hospitalizations; 50.3% of patients were male, 38.5% were aged 18 to 64 years, 45.0% were aged 65 to 84 years, and 16.4% were 85 years or older for the selected time-sensitive medical conditions from 2017 through 2021. The odds of in-hospital mortality for sepsis increased 27% from the prepandemic to the pandemic periods at urban hospitals (odds ratio [OR], 1.27; 95% CI, 1.25-1.29) and 35% at rural hospitals (OR, 1.35; 95% CI, 1.30-1.40). In-hospital mortality for pneumonia had similar increases at urban (OR, 1.48; 95% CI, 1.42-1.54) and rural (OR, 1.46; 95% CI, 1.36-1.57) hospitals. Increases in mortality for these 2 conditions showed a dose-response association with the community COVID-19 level (low vs high COVID-19 burden) for both rural (sepsis: 22% vs 54%; pneumonia: 30% vs 66%) and urban (sepsis: 16% vs 28%; pneumonia: 34% vs 61%) hospitals. The odds of mortality for acute myocardial infarction increased 9% (OR, 1.09; 95% CI, 1.06-1.12) at urban hospitals and was responsive to the community COVID-19 level. There were significant increases in mortality for hip fracture at rural hospitals (OR, 1.32; 95% CI, 1.14-1.53) and for gastrointestinal hemorrhage at urban hospitals (OR, 1.15; 95% CI, 1.09-1.21). No significant change was found in mortality for stroke overall. In this cohort study, in-hospital mortality for time-sensitive conditions increased during the COVID-19 pandemic. Mobilizing strategies tailored to the different needs of urban and rural hospitals may help reduce the likelihood of excess deaths during future public health crises.

Value of multidetector computed tomography angiography in severe non-variceal upper gastrointestinal bleeding: a retrospective study in a referral bleeding unit.

Non-variceal upper gastrointestinal bleeding is a common gastroenterological emergency associated with significant morbidity and mortality. Upper gastrointestinal endoscopy is currently recommended as the gold standard modality for both diagnosis and treatment. As historically played a limited role in the diagnosis of acute non-variceal upper gastrointestinal bleeding, multidetector-row computed tomography angiography is emerging as a promising tool in the diagnosis of non-variceal upper gastrointestinal bleeding, especially for severe cases. However, to date, evidence concerning the role of multidetector-row computed tomography angiography in the non-variceal upper gastrointestinal bleeding diagnosis is still lacking. The purpose of this study was to retrospectively investigate the diagnostic performance of emergent multidetector-row computed tomography angiography performed prior to any diagnostic modality or following urgent upper endoscopy to identify the status, the site, and the underlying etiology of severe non-variceal upper gastrointestinal bleeding. Institutional databases were reviewed in order to identify severe acute non-variceal upper gastrointestinal bleeding patients who were admitted to our bleeding unit and were referred for emergent multidetector-row computed tomography angiography prior to any hemostatic treatment (< 3h) or following (< 3h) endoscopy, between December 2019 and October 2022. The study aim was to evaluate the diagnostic performance of multidetector-row computed tomography angiography to detect the status, the site, and the etiology of severe non-variceal upper gastrointestinal bleeding with endoscopy, digital subtraction angiography, surgery, pathology, or a combination of them as reference standards. A total of 68 patients (38 men, median age 69years [range 25-96]) were enrolled. The overall multidetector-row computed tomography angiography sensitivity, specificity, and accuracy to diagnose bleeding status were 77.8% (95% CI: 65.5-87.3), 40% (95% CI: 5.3-85.3), and 75% (95% CI: 63.0-84.7), respectively. Finally, the overall multidetector-row computed tomography angiography sensitivity to identify the bleeding site and the bleeding etiology were 92.4% (95% CI: 83.2-97.5) and 79% (95% CI: 66.8-88.3), respectively. Although esophagogastroduodenoscopy is the mainstay in the diagnosis and treatment of most non-variceal upper gastrointestinal bleeding cases, multidetector-row computed tomography angiography seems to be a feasible and effective modality in detecting the site, the status, and the etiology of severe acute non-variceal upper gastrointestinal bleeding. It may play a crucial role in the management of selected cases of non-variceal upper gastrointestinal bleeding, especially those clinically severe and/or secondary to rare and extraordinary rare sources, effectively guiding timing and type of treatment. However, further large prospective studies are needed to clarify the role of multidetector-row computed tomography angiography in the diagnostic process of acute non-variceal upper gastrointestinal bleeding.
