A Practical Guide to the Evaluation of Small Bowel Bleeding
Gastrointestinal bleeding is a common clinical problem encountered in both the inpatient and outpatient settings. Although the evaluation of upper and lower gastrointestinal bleeding is often straightforward, bleeding from the small bowel may pose a clinical challenge. In this article, we review the indications, modalities, and differential diagnoses of small bowel bleeding. On completion of the article, clinicians should be able to identify common causes of small bowel bleeding, understand the advantages and disadvantages of the modalities used to evaluate small bowel bleeding, and enact a stepwise management approach to the patient with presumed small bowel bleeding.Colon Ischemia: An Update for Clinicians
Colon ischemia (CI) is an underrecognized entity associated with high morbidity and mortality. Establishing the diagnosis and initiating appropriate and timely treatment is critical for improving outcomes. Colon ischemia is a disease spectrum that requires a full understanding for recognition and treatment. This review outlines the full spectrum of CI management from initial presentation to medical and surgical treatment.Peripheral Arterial Disease: Diagnosis and Management
Peripheral arterial disease is a common but underdiagnosed and undertreated disorder with substantial morbidity and mortality. The pathophysiology of peripheral arterial disease and the risk factors for developing it are similar to those for atherosclerotic disease occurring at other sites. Peripheral arterial disease can be diagnosed accurately with simple, noninvasive, office-based tests that measure the severity of the disease and provide valuable prognostic information. Optimal medical therapy includes a supervised exercise program, tobacco cessation, and modification of treatable risk factors.
