low gastrointestinal bleeding

Background: Colorectal cancer (CRC) is the most prevalent cancer with high mortality worldwide. We aimed to evaluate the incidence of CRC based on the positive fecal immunochemical test (FIT) result in the Iranian population. Methods: The present study was conducted on the health assessment data recorded in the SINA (Integrated Health Information System) in 2018 and 2019 from individuals who had participated in the national program, including asymptomatic people aged 50-69 years or had risk factors of CRC such as family or past personal history of CRC as well as symptomatic individuals, for the early detection and prevention of CRC in Mashhad, Iran...

BACKGROUND: Cardiac surgery triggers a strong inflammatory reaction, which carries significant clinical consequences. Corticosteroids have been suggested as a potential perioperative strategy to reduce inflammation and help prevent postoperative complications. However, the safety and effectiveness of perioperative corticosteroid use in adult cardiac surgery is uncertain. This is an update of the 2011 review with 18 studies added. OBJECTIVES: Primary objective: to estimate the effects of prophylactic corticosteroid use in adults undergoing cardiac surgery with cardiopulmonary bypass on the: - co-primary endpoints of mortality, myocardial complications, and pulmonary complications; and - secondary outcomes including atrial fibrillation, infection, organ injury, known complications of steroid therapy, prolonged mechanical ventilation, prolonged postoperative stay, and cost-effectiveness...

Objective: To evaluate the Shock Index (SI) as a predictive tool for triage of gastrointestinal bleeding (GI) in the prehospital setting, assessing its correlation with mortality, admission rates, and hospital length of stay. Methods: In this retrospective cohort study, we analyzed data from the ESO Data Collaborative encompassing EMS records from the year 2022, focusing on 1525 patients with a primary GI bleeding diagnosis. The primary measure was the SI, calculated at initial contact and highest recorded prior to ED arrival...

BACKGROUND: The precision of clinical criteria and the utility of liver biopsy for diagnosis or prognosis remain unclear in patients with alcohol-associated hepatitis (AH). We systematically reviewed the literature to answer these questions. METHODS: Four databases were searched for studies describing the precision of clinical criteria (National Institute on Alcohol Abuse and Alcoholism, European Association for Study of Liver, or classical) and the role of histology in AH...

INTRODUCTION: Specialist centres have been developed to deliver high-quality Hepatology care. However, there is geographical inequity in accessing these centres in the United Kingdom (UK). We aimed to assess the impact of these centres on decompensated cirrhosis patient outcomes and understand which patients transfer to specialist centres. METHODS: A UK multicentred retrospective observational study was performed including emergency admissions for patients with decompensated cirrhosis in November 2019...

INTRODUCTION: Over 90% of the patients with familial adenomatous polyposis (FAP) will develop duodenal adenomas. AIM: The aim of this study was to evaluate the effectiveness and safety of endoscopic excision of large duodenal adenomas in FAP patients. METHODS: All FAP patients from a familial risk clinic submitted to endoscopic therapy for duodenal adenomas ≥10 mm between January 2010 and February 2021 were included. RESULTS: From 151 FAP families, 22 patients (50 lesions) were included: 54...

Small bowel vascular malformation disease (SBVM) commonly causes obscure gastrointestinal bleeding (OGIB). However, the pathogenetic mechanism and the role of lncRNAs in SBVM remain largely unknown. Here, we found that hypoxia and low-glucose environments co-augment angiogenesis and existed in SBVM. Mechanistically, hypoxia and low-glucose environments supported angiogenesis via activation of hypoxia and glucose deprivation-induced lncRNA (HGDILnc1) transcription by increasing binding of the NeuroD1 transcription factor to the HGDILnc1 promoter...

INTRODUCTION: Intravascular papillary endothelial hyperplasia (IPEH), originally described by Pierre Masson in 1923, is a benign vascular lesion characterised by the reactive proliferation of endothelial cells. This tumour typically manifests on the fingers, head, neck, or trunk. However, involvement of other organ systems, including abdominal organs, is possible although exceedingly rare. CASE PRESENTATION: A 57-year-old male patient presented to the emergency department with a 24-h history of recurrent light-headedness...

BACKGROUND AND AIMS: Post-operative stricture is serious common adverse event following extensive endoscopic submucosal dissection (ESD) in the esophagus. The self-assembling peptide (SA) gel has been shown to promote tissue healing and re-epithelialization. We aimed to evaluate the effect of the SAP gel for esophageal stricture prevention after ESD. METHODS: Multicenter prospective study of patients who underwent esophageal ESD followed by SAP gel application between March 2022 to December 2023...

BACKGROUND: To avoid acute variceal bleeding in cirrhosis, current guidelines recommend screening for high-risk esophageal varices (EVs) by determining variceal size and identifying red wale markings. However, visual measurements of EV during routine endoscopy are often inaccurate. AIM: To determine whether biopsy forceps (BF) could be used as a reference to improve the accuracy of binary classification of variceal size. METHODS: An in vitro self-made EV model with sizes ranging from 2 to 12 mm in diameter was constructed...

INTRODUCTION AND SIGNIFICANCE: Portal vein thrombosis (PVT) is not commonly observed in patients, particularly those who have gone through neonatal intensive care unit (NICU) stays and had umbilical catheters. Although PVT can potentially cause hypertension and gastrointestinal bleeding it is highly unusual for this condition to manifest during childhood. CASE PRESENTATION: The authors present a case of a 10-year-old child who developed portal hypertension, esophageal varices, and multiple thrombophilia associated mutations...

The study aimed to identify prognostic factors for patients with acute lower gastrointestinal bleeding and to develop a high-accuracy prediction tool. The analysis included 8254 cases of acute hematochezia patients who were admitted urgently based on the judgment of emergency physicians or gastroenterology consultants (from the CODE BLUE J-study). Patients were randomly assigned to a derivation cohort and a validation cohort in a 2:1 ratio using a random number table. Assuming that factors present at the time of admission are involved in mortality within 30 days of admission, and adding management factors during hospitalization to the factors at the time of admission for mortality within 1 year, prognostic factors were established...

BACKGROUND: Stress ulcers in patients with traumatic brain injury (TBI) and spinal cord injury (SCI) present significant morbidity and mortality risks. Despite the low reported stress ulcer rates, stress ulcer prophylaxis (SUP) is widely administered in neurocritical care. It was hypothesized that universal SUP administration may not be associated with reduced rates of complications across all neurocritical care patients. METHODS: This retrospective study encompassed neurocritical care patients aged ≥18 with moderate or severe TBI or SCI, admitted to the intensive care unit (ICU) between October 2020 and September 2021, across six level I trauma centers...

Appendicular mucinous neoplasms, constituting less than 1% of gastrointestinal tract neoplasms, are heterogeneous entities. They may be asymptomatic, discovered incidentally, or present as large tumors due to mucin accumulation. The lack of standardized treatment complicates management. Imaging studies, particularly CT scans, are crucial for diagnosis and follow-up. This case report presents two clinical cases of women in their sixth and seventh decades of life with a history of lower gastrointestinal bleeding, mild anemia in laboratory studies, and incomplete colonoscopies...

Background and Objectives: Alcoholic hepatitis (AH) poses a medical challenge, causing moderately severe to life-threatening episodes with high short- and long-term mortality. This study aimed to explore real-world corticosteroid utilization in severe AH, response predictors, and patient outcomes. Materials and Methods: We conducted a retrospective study on patients admitted for severe AH, defined as a Maddrey Discriminant Function score equal to or above 32, at a tertiary care center. We reviewed patients' medical observation charts to identify corticosteroid prescriptions, reasons for ineligibility, and response rates...

BACKGROUND AND PURPOSE: This prospective study aimed to investigate adaptive magnetic resonance (MR)-guided stereotactic body radiation therapy (MRgSBRT) with rectal spacer for localized prostate cancer (PC) and report 1-year clinical outcomes. MATERIALS AND METHODS: Thirty-four consecutive patients with low- to high-risk localized PC that underwent 5-fraction adaptive MRgSBRT with rectal spacer were enrolled. The dosimetric comparison was performed on a risk- and age-matched cohort treated with MRgSBRT but without a spacer at a similar timepoint...

BACKGROUND: Proton pump inhibitors (PPI) are frequently used in patients with cirrhosis. AIMS: This study aimed to determine whether PPI use is associated with the prognosis of cirrhotic patients. METHODS: We conducted a multicentre retrospective cohort study involving 1485 patients who had experienced hepatic encephalopathy (HE) from 7 referral centres in Korea. The primary outcome was overall survival and secondary outcomes included the development of cirrhotic complications, including recurrent HE, spontaneous bacterial peritonitis (SBP), hepatorenal syndrome (HRS), and gastrointestinal bleeding...

Chronic expanding hematoma (CEH), first reported in 1968, is a hematoma that gradually enlarges over a long course of time after an initial period of bleeding. It can occur anywhere in the body; however, there are many reports of its occurrence in the thoracic cavity. Primary hepatic CEH is extremely rare. In this current study, we report on a case of primary hepatic CEH diagnosed preoperatively, with a review of the literature. A 68-year-old man presented with liver dysfunction. Abdominal computed tomography revealed a giant cystic tumor in the left lobe of the liver, with a longer axis of approximately 12 cm...

Arterial-enteric fistulas occur from a multitude of causes, especially following surgical manipulation of vasculature. The development of an iliac artery-enteric fistula (IEF) occurs rarely in patients with failed pancreatic transplants. IEFs warrant urgent intervention due to the high mortality from hemorrhagic and septic shock. The diagnosis can be delayed by a lack of suspicion, the low sensitivity of diagnostic tests, and the nonspecific signs of fistulas on computed tomography. The management of IEFs is adapted from guidelines for arterial-enteric fistulas of other causes, with little consensus on ideal vascular reconstruction and postoperative antimicrobial management...

Gastrointestinal stromal tumors (GISTs) typically occur in the stomach and proximal small intestine but can also be found in any other part of the digestive tract, including the abdominal cavity, albeit rarely. In the present case, the tumor was resected endoscopically through the anterior gastric wall. Computed tomography (CT) scan and gastroscopy of a 60-year-old woman revealed submucosal lesions in the gastric body. The possibility of a stromal tumor was considered more likely. The endoscopic surgery was performed under endotracheal anesthesia...
