Acute gastrointestinal bleeding
1Gastroenterology Division and Department of Medicine, Duke University Medical Center, Durham, NC 27710, USA.
Acute gastrointestinal bleeding is a common disorder with a wide spectrum of presentations that may encompass multiple clinical scenarios. Initial hemodynamic assessment and resuscitation are critical. Once accomplished, the source of bleeding should be localized, active bleeding should be stopped, the underlying abnormality should be treated, and recurrent bleeding should be prevented. The means to accomplish these goals depends on the specific clinical situation. For most forms of upper gastrointestinal bleeding, early endoscopy is the cornerstone of diagnosis and management. It can predict and improve clinical outcomes. A variety of endoscopic and pharmacologic modalities are effective at achieving and maintaining hemostasis. The optimum means of evaluation and treatment of acute lower gastrointestinal bleeding is less clear and is now evolving. Endoscopy (usually expectant, less often early) is widely used and effective for diagnosis but has unproven therapeutic benefits. Angiography is effective (diagnostically and/or therapeutically) in certain situations. Surgery offers the opportunity for definitive therapy at the cost of higher morbidity. At this time, the approach to evaluation and management should be based on the specific clinical situation and available local expertise.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
