Time trends and impact of upper and lower gastrointestinal bleeding and perforation in clinical practice.

Objectives: Changing patterns in medical practice may contribute to temporal changes in the incidence of upper and lower gastrointestinal (GI) complications. There are limited data on the incidence of lower GI complications in clinical practice and most studies that have been done have serious methodological limitations to inferring the actual burden of this problem. The aims of this study were to analyze time trends of hospitalizations resulting from GI complications originating both from the upper and lower GI tract in the general population, and to determine the risk factors, severity, and clinical impact of these GI events.

A nationwide study of mortality associated with hospital admission due to severe gastrointestinal events and those associated with nonsteroidal antiinflammatory drug use.

Background: The worst outcome of gastrointestinal complications is death. Data regarding those associated with nonsteroidal antiinflammatory drug (NSAID) or aspirin use are scarce.

Aim: To determine mortality associated with hospital admission due to major gastrointestinal (GI) events and NSAID/aspirin use.
