First-Line Treatment Options for Upper Gastrointestinal Bleeding

When it comes to managing upper gastrointestinal (GI) bleeding, endoscopic intervention is often the first choice for invasive treatment, while pharmacological therapy primarily relies on proton pump inhibitors (PPIs). These medications are highly effective in reducing gastric acid secretion and are considered the cornerstone of medical treatment in such cases.

Importance of Acid Suppression in GI Bleeding

Following an episode of upper GI bleeding, patients are typically advised to stop oral intake of food and liquids temporarily. Intravenous or oral administration of PPIs or H2 receptor antagonists is initiated to modulate the pH level within the gastrointestinal tract. This is crucial because when the gastric pH falls below 5.0, newly formed blood clots can be rapidly broken down, hindering the natural clotting process. Conversely, when the pH rises above 6.0, platelet aggregation and overall coagulation function are significantly enhanced. Therefore, maintaining an optimal gastric pH through medication is essential for effective hemostasis and mucosal protection.

Role of Emergency Endoscopy

In addition to pharmacological treatment, emergency gastroscopy plays a vital role in both diagnosing and treating upper GI bleeding. It is generally recommended that patients undergo endoscopic evaluation within 24 hours of the bleeding episode. This allows for precise identification of the bleeding source, and therapeutic interventions such as endoscopic injection, thermal coagulation, or the application of titanium clips can be performed during the same procedure.

Other Treatment Approaches

Besides endoscopy and acid-suppressive drugs, other treatment modalities may also be employed depending on the patient's condition. These include the use of somatostatin or its analogs, which help reduce splanchnic blood flow and lower the risk of rebleeding. Oral hemostatic agents may be considered in certain cases, and for patients who continue to bleed despite initial therapies, interventional radiology techniques such as arterial embolization can be a life-saving option.

In summary, the management of upper gastrointestinal bleeding involves a combination of medical and endoscopic strategies. Prompt use of proton pump inhibitors, early endoscopic intervention, and consideration of adjunctive therapies are key components in achieving successful outcomes and preventing complications.
