Upper gastrointestinal tract bleeding. Predisposing factors, diagnosis, and therapy

Area of Science:

• Gastroenterology
• Internal Medicine

Background:

• Upper gastrointestinal (GI) bleeding mortality has remained constant at 10% over the past 40 years.
• Numerous drugs can precipitate upper GI bleeding by compromising the gastric mucosal barrier.
• Aspirin-induced gastric mucosal injury and subsequent GI bleeding are well-documented, with ongoing research into underlying mechanisms.

Purpose of the Study:

• To review the current approach to patients presenting with upper GI tract bleeding.
• To describe available therapeutic interventions for GI tract bleeding.
• To compare experimental laser therapies for GI bleeding.

Main Methods:

• Review of patient management strategies including resuscitation, history, physical examination, and diagnostic procedures.
• Description of established therapies: gastric lavage, drug therapy, endoscopic control, electrocautery, thermal probe, tissue adhesive.
• Comparison of argon laser and neodymium-yttrium aluminum garnet (Nd:YAG) laser therapies.

Main Results:

• No pharmacologic or endoscopic therapies for upper GI tract bleeding have been definitively proven effective.
• Established therapies like gastric lavage and endoscopic interventions are described.
• Experimental laser therapies, including argon and Nd:YAG lasers, are discussed.

Conclusions:

• The persistent high mortality from upper GI bleeding underscores the need for more effective treatments.
• A systematic approach to patient evaluation and management is crucial.
• Further research into novel therapeutic modalities, including laser technologies, is warranted.
