Upper gastrointestinal bleeding (UGIB) is a significant concern in children, contributing to 6-20% of cases in pediatric intensive care units. This study evaluates the roles of Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drug (NSAID) usage in the etiology of UGIB in children, with a particular focus on trends observed during the COVID-19 pandemic. We conducted a retrospective analysis of 103 pediatric patients who underwent esophagogastroduodenoscopy (EGD) for UGIB between January 2015 and December 2023. Of these, 88 patients were included in the final analysis, where the source of bleeding was successfully identified. Hematemesis was the most common presentation, and the source of bleeding was identified in 85.43% of cases. The prevalence of H. pylori infection remained stable across the pre-pandemic (39.7%) and post-pandemic (36.7%) periods. However, NSAID usage increased nearly threefold during the pandemic, with 36.7% of post-pandemic UGIB cases associated with NSAID use, compared to 12.1% pre-pandemic. These findings underscore the significant roles of H. pylori and NSAID use in pediatric UGIB, with a notable increase in NSAID-related cases during the pandemic.

Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is a common medical emergency in clinical practice. While the incidence has significantly reduced, the mortality rates have not undergone a similar reduction in the last few decades, thus presenting a significant challenge. This editorial outlines the key causes and risk factors of ANVUGIB and explores the current standards and recent updates in risk assessment scoring systems for predicting mortality and endoscopic treatments for achieving hemostasis. Since ANUVGIB predominantly affects the elderly population, the impact of comorbidities may be responsible for the poor outcomes. A thorough drug history is important due to the increasing use of antiplatelet agents and anticoagulants in the elderly. Early risk stratification plays a crucial role in deciding the line of management and predicting mortality. Emerging scoring systems such as the ABC (age, blood tests, co-morbidities) score show promise in predicting mortality and guiding clinical decisions. While conventional endoscopic therapies remain cornerstone approaches, novel techniques like hemostatic powders and over-the-scope clips offer promising alternatives, particularly in cases refractory to traditional modalities. By integrating validated scoring systems and leveraging novel therapeutic modalities, clinicians can enhance patient care and mitigate the substantial morbidity and mortality associated with ANVUGIB.

There are very few reports of bloodborne metastasis of lung adenocarcinoma to the gastrointestinal tract, primarily due to poor prognosis and short survival rate of metastasized carcinoma. We present a case of a 79-year-old man with a medical history of lung adenocarcinoma, who presented with complaints of weakness and melena for 1 week. He had symptomatic anemia, for which he was transfused with blood. Esophagogastroduodenoscopy showed a 10 mm sessile polyp in the gastric body that was removed. One month later, the patient presented with a similar complaint, and another esophagogastroduodenoscopy revealed 2 ulcerated lesions in the second portion of the duodenum. These lesions were treated by hemostatic clip placement and heater probe coagulation. Biopsy of lesions demonstrated thyroid transcription factor 1 and Napsin-positive tumor cells, consistent with lung adenocarcinoma. Owing to the poor prognosis of lung adenocarcinoma metastasizing to the lymph nodes, stomach, and duodenum, the patient was transferred to hospice care.

UNASSIGNED: The neutrophil-lymphocyte ratio (NLR) is a simple marker of systemic inflammatory responses. The present study aims to evaluate the prognostic significance of the NLR on admission day in predicting outcomes for patients with upper gastrointestinal bleeding (UGIB), which is a prevalent medical emergency.
UNASSIGNED: 726 patients who were admitted to our clinic between January 2019 and December 2022 diagnosed with UGIB, and who underwent necessary examinations, were included in the study. The patients\' Glasgow-Blatchford Score (GBS), Full Rockall Score (FRS), and NLR levels were calculated at the first admission. Outcomes were defined as in-hospital mortality, need for blood transfusion, surgical treatment and endoscopic therapy. Patients were categorized into four groups using NLR quartile levels to compare their clinical characteristics, Glasgow Blatchford Score, Full Rockall Score levels, and prognosis. Secondary, we modified FRS and GBS by adding NLR, respectively. We used area under the receiver operating characteristic curve (AUROC) to assess the accuracy of risk prediction for NLR, NLR-GBS, and NLR-FRS improved models.
UNASSIGNED: Of 726 patients, 6% died in hospital, 23.9% received endoscopic interventon, 4.8% received surgical treatment, and 46.4% received transfusion therapy. Multifactorial logistic regression showed that a high level of NLR was a risk factor for death in patients with UGIB (p = 0.028). NLR, GBS, FRS, NLR-GBS, and NLR-FRS have sufficient accuracy in predicting inpatient mortality, endoscopic treatment, and transfusion treatment, and the differences are statistically significant (p < 0.05). In the comprehensive prediction of adverse outcomes, NLR-GBS has the highest AUROC, and in predicting inpatient mortality, NLR-FRS has the highest AUROC.
UNASSIGNED: For UGIB patients, a high NLR was strongly associated with high risk UGIB. Combined testing with the GBS and FRS can achieve good predictive results, which is valuable in guiding the pre-screening and triage of emergency nursing care and clinical treatment to ensure that patients receive rapid and effective treatment and improve the quality of care.

UNASSIGNED: Upper gastrointestinal bleeding due to primary aortoesophageal fistula is a rare clinical condition burdened with high mortality rate. However, the outcomes are closely related to the level of clinical awareness, the complementary and multidisciplinary approach during the diagnostic workup, and the selected treatment option.
UNASSIGNED: We present an atypical case of an aneurysm of the thoracoabdominal aorta complicated with primary aortoesophageal fistula (AEF). A 55-year-old male with no previous diseases, presented with prolonged and intense back pain and upper gastrointestinal bleeding. The gastroscopy detected an unusual culprit lesion in the distal esophagus resembling an esophageal wall defect, and the computed tomography revealed an aneurysm of the thoracoabdominal aorta, remarkable surrounding hematoma, and active contrast extravasation. Despite the urgent surgical repair, a lethal outcome occurred. AEF patients require high clinical awareness and complementary multidisciplinary approach in order to provide a rapid diagnosis and optimal treatment.

UNASSIGNED: To develop a model that integrates radiomics features and clinical factors to predict upper gastrointestinal bleeding (UGIB) in patients with decompensated cirrhosis.
UNASSIGNED: 104 decompensated cirrhosis patients with UGIB and 104 decompensated cirrhosis patients without UGIB were randomized according to a 7:3 ratio into a training cohort (n = 145) and a validation cohort (n = 63). Radiomics features of the abdominal skeletal muscle area (SMA) were extracted from the cross-sectional image at the largest level of the third lumbar vertebrae (L3) on the abdominal unenhanced multi-detector computer tomography (MDCT) images. Clinical-radiomics nomogram were constructed by combining a radiomics signature (Rad score) with clinical independent risk factors associated with UGIB. Nomogram performance was evaluated in calibration, discrimination, and clinical utility.
UNASSIGNED: The radiomics signature was built using 11 features. Plasma prothrombin time (PT), sarcopenia, and Rad score were independent predictors of the risk of UGIB in patients with decompensated cirrhosis. The clinical-radiomics nomogram performed well in both the training cohort (AUC, 0.902; 95% CI, 0.850-0.954) and the validation cohort (AUC, 0.858; 95% CI, 0.762-0.953) compared with the clinical factor model and the radiomics model and displayed excellent calibration in the training cohort. Decision curve analysis (DCA) demonstrated that the predictive efficacy of the clinical-radiomics nomogram model was superior to that of the clinical and radiomics model.
UNASSIGNED: Clinical-radiomics nomogram that combines clinical factors and radiomics features has demonstrated favorable predictive effects in predicting the occurrence of UGIB in patients with decompensated cirrhosis. This helps in early diagnosis and treatment of the disease, warranting further exploration and research.

Gastrointestinal bleeding (GIB) is a significant public health concern, predominantly associated with high morbidity. However, there have been no reports investigating the trends of GIB in Japan using nationwide data. This study aims to identify current trends and issues in the management of GIB by assessing Japan\'s national data. We analyzed National Database sampling data from 2012 to 2019, evaluating annual hospitalization rates for major six types of GIB including hemorrhagic gastric ulcers, duodenal ulcers, esophageal variceal bleeding, colonic diverticular bleeding, ischemic colitis, and rectal ulcers. In this study, hospitalization rates per 100,000 indicated a marked decline in hemorrhagic gastric ulcers, approximately two-thirds from 41.5 to 27.9, whereas rates for colonic diverticular bleeding more than doubled, escalating from 15.1 to 34.0. Ischemic colitis rates increased 1.6 times, from 20.8 to 34.9. In 2017, the hospitalization rate per 100,000 for colonic diverticular bleeding and ischemic colitis surpassed those for hemorrhagic gastric ulcers (31.1, 31.3, and 31.0, respectively). No significant changes were observed for duodenal ulcers, esophageal variceal bleeding, or rectal ulcers. The findings of this study underscore a pivotal shift in hospitalization frequencies from upper GIB to lower GIB in 2017, indicating a potential shift in clinical focus and resource allocation.

BACKGROUND: Ulcer erosion into the cystic artery is a rare cause of bleeding in duodenal ulcers, with only a limited number of cases described in the literature. Historically, treatment has predominantly involved surgical intervention. We present three cases of duodenal ulcer bleeding due to cystic artery erosion, which were successfully managed with cystic artery embolization.
METHODS: This case series includes three male patients with duodenal ulcer bleeding, aged 90, 81, and 82 years, respectively, and no prior history of biliary system disorders. The ulcer locations were identified as two in the post-bulbar region and one in the anterior bulb. After the failure of medical and endoscopic treatment, transcatheter arterial embolization was adopted. Initial angiography did not reveal any contrast medium extravasation. Empirical embolization of the gastroduodenal artery using gelatin sponge particles and coils failed to achieve hemostasis. Super-selective cystic artery angiography confirmed the source of bleeding as the cystic artery. One patient was embolized with gelatin sponge particles and coils, while the other two patients were embolized with N-butyl-cyanoacrylate. All patients achieved successful hemostasis without gallbladder infraction.
CONCLUSIONS: Cystic artery embolization proved to be a minimally invasive technique for achieving hemostasis in these cases, indicating that it may be a safe and effective alternative to surgery for this uncommon cause of upper gastrointestinal bleeding. Validation through further studies is warranted.

Splenic venous hypertension or left-sided portal hypertension is a rare condition caused by an obstruction of the splenic vein. Usually, it presents with upper gastrointestinal bleeding in the absence of liver disease. Etiologies can be classified based on the mechanism of development of splenic vein hypertension: compression, stenosis, inflammation, thrombosis, and surgically decreased splenic venous flow. Diagnosis is established by various imaging modalities and should be suspected in patients with gastric varices in the absence of esophageal varices, splenomegaly, or cirrhosis. The management and prognosis vary depending on the underlying etiology but generally involve reducing splenic venous pressure. The aim of this review was to summarize the etiologies of splenic venous hypertension according to the mechanism of development.

UNASSIGNED: Hemostatic powders are used as second-line treatment in acute gastrointestinal (GI) bleeding (AGIB). Increasing evidence supports the use of TC-325 as monotherapy in specific scenarios. This prospective, multicenter study evaluated the performance of TC-325 as monotherapy for AGIB.
UNASSIGNED: Eighteen centers across Europe and USA contributed to a registry between 2016 and 2022. Adults with AGIB were eligible, unless TC-325 was part of combined hemostasis. The primary endpoint was immediate hemostasis. Secondary outcomes were rebleeding and mortality. Associations with risk factors were investigated (statistical significance at P≤0.05).
UNASSIGNED: One hundred ninety patients were included (age 51-81 years, male: female 2:1), with peptic ulcer (n=48), upper GI malignancy (n=79), post-endoscopic treatment hemorrhage (n=37), and lower GI lesions (n=26). The primary outcome was recorded in 96.3% (95% confidence interval [CI]: 92.6-98.5) with rebleeding in 17.4% (95%CI 11.9-24.1); 9.9% (95%CI 5.8-15.6) died within 7 days, and 21.7% (95%CI 15.6-28.9) within 30 days. Regarding peptic ulcer, immediate hemostasis was achieved in 88% (95%CI 75-95), while 26% (95%CI 13-43) rebled. Higher ASA score was associated with mortality (OR 23.5, 95%CI 1.60-345; P=0.02). Immediate hemostasis was achieved in 100% of cases with malignancy and post-intervention bleeding, with rebleeding in 17% and 3.1%, respectively. Twenty-six patients received TC-325 for lower GI bleeding, and in all but one the primary outcome was achieved.
UNASSIGNED: TC-325 monotherapy is safe and effective, especially in malignancy or post-endoscopic intervention bleeding. In patients with peptic ulcer, it could be helpful when the primary treatment is unfeasible, as bridge to definite therapy.
