Introduction

Gastrointestinal bleeding represents a significant clinical challenge, encompassing a spectrum of disorders ranging from benign mucosal lesions to life-threatening hemorrhages. This theory aims to provide a comprehensive overview of GIB, exploring its diverse etiology, diagnostic modalities, and management strategies to optimize patient outcomes arises from a myriad of underlying etiologies, classified into upper and lower gastrointestinal sources based on the anatomical site of bleeding. Upper GIB commonly originates from peptic ulcers, erosive gastritis, esophageal varices, Mallory-Weiss tears, and gastroduodenal erosions.

Description

Lower may result from colonic diverticula, angiodysplasia, inflammatory bowel disease, colorectal polyps, and colorectal cancer. Other less common causes include arteriovenous malformations, Dieulafoy lesions, and aortoenteric fistulas. The pathophysiology of varies depending on the underlying etiology but generally involves disruption of the mucosal barrier integrity, leading to extravasation of blood into the gastrointestinal lumen. Mechanisms contributing to mucosal injury include acid-peptic damage, ischemia, inflammation, and vascular abnormalities. In some cases, excessive anticoagulation or antiplatelet therapy may exacerbate bleeding by impairing hemostatic mechanisms. The clinical presentation of GIB ranges from occult bleeding with subtle symptoms to overt hemorrhage with hemodynamic instability. Common manifestations include hematemesis vomiting of blood, melena black, tarry stools, hematochezia bright red or maroon-colored stools, and signs of hemodynamic compromise such as hypotension, tachycardia, and pallor. The severity of symptoms often correlates with the rate and volume of blood loss, necessitating prompt evaluation and intervention. The diagnostic workup for involves a systematic approach aimed at identifying the source and severity of bleeding. Initial evaluation includes a detailed medical history, physical examination, and assessment of hemodynamic stability. Laboratory studies, including complete blood count, coagulation profile, and serum chemistries, help assess the extent of blood loss and guide resuscitative measures. Endoscopic evaluation, including esophagogastroduodenoscopy and colonoscopy, serves as the cornerstone of GIB diagnosis, allowing direct visualization and intervention. Radiographic imaging modalities, such as angiography, computed tomography angiography and nuclear scintigraphy, may be employed for localization of bleeding sources not accessible by endoscopy. Management of GIB entails a multidisciplinary approach involving resuscitation, localization, and definitive treatment of bleeding sources. Initial resuscitative measures include intravenous fluid resuscitation, blood transfusion, and correction of coagulopathy. Hemodynamically unstable patients may require urgent intervention with blood products and vasopressor support.

Conclusion

Gastrointestinal bleeding represents a diverse array of disorders with potentially life-threatening consequences. A systematic approach to diagnosis and management is essential for optimizing patient outcomes and minimizing morbidity and mortality associated with continued advancements in endoscopic and radiographic techniques, as well as the development of novel therapeutic agents, hold promise for further improving the management of GIB in the future. Advances in diagnostic modalities have revolutionized the approach to enabling rapid and accurate localization of bleeding sources. Endoscopic techniques, including capsule endoscopy and double-balloon enteroscopy, offer unparalleled visualization of the entire gastrointestinal tract, facilitating the detection of obscure bleeding sources. Complementary imaging modalities, such as angiography and magnetic resonance enterography, provide valuable anatomical information and aid in the localization of hemorrhagic lesions.
