Upper gastrointestinal bleeding.

PURPOSE OF REVIEW: This review provides an update on the management of upper gastrointestinal bleeding with special attention to patient preparation, sedation, hemostatic techniques, and postprocedure care. RECENT FINDINGS: In a large multicenter clinical trial, nurse-administered propofol sedation had a complication rate of less than 0.2%. The optimal management for an ulcer with adherent clot was confirmed by a meta-analysis to be clot removal and endoscopic treatment of the underlying lesion. A number of prospective studies have demonstrated that capsule endoscopy is the most sensitive imaging modality for identifying lesions in the small bowel and that double-balloon enteroscopy is the least invasive modality available for the management of these lesions. SUMMARY: This update describes many recent advances in the diagnosis and management of upper gastrointestinal bleeding. However, clearly, much work needs to be done in this field. Since propofol is not available for use in all endoscopy units, is there a better alternative for deep sedation? Rebleeding occurs in 20% of patients after endoscopic therapy, and so can we provide better outcomes with newer technologies (endoscopic suturing devices)? Finally, what is the best management for Helicobacter pylori-negative, nonsteroidal antiinflammatory drug-negative ulcer patients?

Inflammatory bowel disease.

Inflammatory bowel disease is a complicated condition, including Crohn's disease, ulcerative colitis, microscopic colitis, and indeterminate colitis, that affects the intestine and several extraintestinal sites. There has been much debate regarding whether Crohn's disease and ulcerative colitis are distinct entities or if they exist along a continuum of the same disease process. In this article, the pathogenic mechanisms and clinical manifestations of inflammatory bowel disease are reviewed, as well as treatment options. Because Crohn's disease and ulcerative colitis are chronic diseases, they have an important economic effect on our healthcare system and the United States as a whole. Some newer and more expensive treatment options may provide overall cost savings in select patient populations because of decreased use of healthcare resources.
