Factors Predicting the Need for Endoscopic Intervention in Non-variceal Upper Gastrointestinal Bleeding

Gastrointestinal system bleedings are medical emergencies and the most common cause of hospital admissions related to digestive system diseases. Gastrointestinal system bleedings are a frequently encountered condition and one of the significant reasons leading to morbidity, mortality, and medical care costs. For acute upper gastrointestinal system bleedings, the annual hospital admission incidence in the United States is approximately 67 per 100,000 adults, making it more common than lower gastrointestinal system bleedings. Approximately 80% of acute upper gastrointestinal system bleedings are attributed to non-variceal causes. Endoscopy is an invasive procedure used for diagnosis and treatment in upper gastrointestinal system bleedings. . In recent years, there has been an increase in endoscopy and endoscopic treatment rates. Except for variceal bleedings, most upper gastrointestinal system bleedings stop without the need for endoscopic intervention. However, some patients require endoscopic intervention and identifying this high-risk group, prone to recurrent bleeding, through non-invasive tests is crucial. In investigators' prospective study, researcher aimed to facilitate the identification of patients who require intervention and undergo endoscopic intervention (e.g., epinephrine injection, hemoclips, thermal coagulation, argon plasma coagulation, etc.) among those who underwent endoscopy within the first 24 hours after admission to the hospital's emergency department with a diagnosis of non-variceal acute upper gastrointestinal system bleeding. Investigators sought to achieve this by determining the relevant parameters related to their clinical and laboratory findings, comorbidities, and demographic characteristics at the time of admission. This approach aims to reduce hospital admissions, hospital stay, and costs, and particularly to minimize interventional procedures during seizures and decrease complications.As of August 2022, patients who applied to the Ankara Bilkent City Hospital emergency department were followed up.

For acute upper gastrointestinal system bleedings, the annual hospital admission incidence in the United States is approximately 67 per 100,000 adults, making it more common than lower gastrointestinal system bleedings. A decrease in the incidence of non-variceal acute upper gastrointestinal system bleeding has been observed compared to previous years, which is believed to be associated with an increase in the use of proton pump inhibitors (PPIs), eradication of Helicobacter pylori (H. pylori), and advancements in endoscopic treatment. Approximately 80% of acute upper gastrointestinal system bleedings are attributed to non-variceal causes.

Endoscopy is an invasive procedure used for diagnosis and treatment in upper gastrointestinal system bleedings. In recent years, there has been an increase in endoscopy and endoscopic treatment rates. Previous studies have identified higher mortality rates, around 5-10% for bleeding due to peptic ulcers, and approximately 15% for esophageal variceal bleedings. The development of modern endoscopy has led to significant advancements in various therapeutic techniques. Mortality related to all causes of upper gastrointestinal system bleedings has declined due to advancements in treatment. In recent years, there has been a decrease in hospitalization duration and mortality, but the total economic burden has significantly increased.

Except for variceal bleedings, most upper gastrointestinal system bleedings stop without the need for endoscopic intervention. However, some patients require endoscopic intervention and identifying this high-risk group, prone to recurrent bleeding, through non-invasive tests is crucial. In cases where endoscopic treatment is insufficient, surgical or interventional radiology procedures such as embolization may be necessary. Endoscopic treatment has led to a reduction in the need for surgery and blood transfusions in patients presenting with upper gastrointestinal system bleeding. The goal of treatment is to prevent complications and deaths. Determining the need for treatment for a patient is clinically and practically easier than predicting who will die or re-bleed.

Gastrointestinal bleedings can lead to various clinical scenarios due to multiple lesion types, and they can occur from any part of the gastrointestinal system, either overtly or covertly. Upper gastrointestinal bleedings are approximately 5 times more common than lower gastrointestinal bleedings. Several scoring systems, such as Glasgow-Blatchford, Rockall, AIMS65, have been developed to predict the need for endoscopic intervention, risk of re-bleeding, and 30-day mortality in non-variceal bleedings.

Emergency upper gastrointestinal endoscopy is performed within the first 12 hours in high-risk patients who present to the hospital's emergency department with acute upper gastrointestinal system bleeding. However, it may not always be feasible to adhere to this timeframe, and endoscopy can be performed up to 24 hours after appropriate resuscitation, depending on the expertise of the personnel.
