Introduction

Endoscopy has become an indispensable tool in the diagnosis and management of digestive bleeding. It provides direct visualization of the gastrointestinal (GI) tract, allowing for accurate identification and treatment of bleeding sources. This article will explore the types of endoscopic procedures used, their diagnostic and therapeutic roles, the preparation and risks involved, and advancements in endoscopic technology [1].

Types of Endoscopic Procedures: Esophagogastroduodenoscopy (EGD): Scope: Upper GI tract, including the esophagus, stomach, and duodenum. Indications: Suspected upper gastrointestinal bleeding (UGIB) from sources such as peptic ulcers, esophageal varices, gastritis, and Mallory-Weiss tears [2].

Colonoscopy: Scope: Entire colon and rectum. Indications: Suspected lower gastrointestinal bleeding (LGIB) from sources such as diverticulosis, colorectal cancer, inflammatory bowel disease (IBD), and hemorrhoids. Flexible Sigmoidoscopy: Scope: Lower part of the colon (sigmoid colon) and rectum. Indications: LGIB evaluation, especially when bleeding is suspected in the distal colon or rectum [3].

Capsule Endoscopy: Scope: Small intestine. Indications: Obscure GI bleeding where the source is not identified by EGD or colonoscopy. The patient swallows a small capsule with a camera that takes pictures throughout the small intestine [4]. Double-Balloon Enteroscopy (DBE): Scope: Entire small intestine. Indications: When capsule endoscopy detects abnormalities, DBE can be used for direct visualization, biopsy, and treatment [5].

Diagnostic Role of Endoscopy: Endoscopy plays a crucial diagnostic role in identifying the exact source and cause of GI bleeding: Direct Visualization: Upper GI Bleeding: EGD can identify and differentiate between various causes such as peptic ulcers, varices, and Mallory-Weiss tears. It allows for direct observation of bleeding sites and their characteristics [6].

Lower GI Bleeding: Colonoscopy helps in diagnosing conditions like diverticulosis, colorectal cancer, angiodysplasia, and IBD. It provides a clear view of the colon and rectum, helping to pinpoint bleeding sources. Tissue Biopsy: During endoscopy, biopsies can be taken from suspicious areas to diagnose malignancies, infections, or inflammatory conditions that might cause bleeding [7].

Therapeutic Role of Endoscopy: Beyond diagnosis, endoscopy is a powerful therapeutic tool in managing GI bleeding: Endoscopic Hemostasis: Injection Therapy: Injection of epinephrine or other sclerosing agents directly into bleeding sites to control hemorrhage. Thermal Coagulation: Using heat to coagulate bleeding vessels, common in treating peptic ulcers [8].

Mechanical Hemostasis: Application of clips or bands to physically close off bleeding vessels or lesions. Band ligation is often used for esophageal varices.Polypectomy and Tumor Resection: Removal of polyps or early-stage tumors during colonoscopy can prevent further bleeding and potential progression to cancer [9].

Argon Plasma Coagulation (APC): A non-contact technique using ionized argon gas to coagulate and control bleeding, especially effective for treating angiodysplasia. Endoscopic Variceal Ligation (EVL): Used specifically for esophageal varices, EVL involves placing rubber bands around varices to stop bleeding and prevent recurrence [10].

Conclusion

Endoscopy plays a pivotal role in the diagnosis and management of digestive bleeding. It allows for direct visualization of the GI tract, precise identification of bleeding sources, and immediate therapeutic intervention. With advancements in technology, the diagnostic and therapeutic capabilities of endoscopy have significantly improved, making it an essential tool in modern gastroenterology. Proper preparation and understanding of the risks associated with endoscopic procedures are crucial for ensuring patient safety and the success of the intervention. As technology continues to evolve, endoscopy will remain at the forefront of diagnosing and treating digestive bleeding, ultimately improving patient outcomes and quality of life.
