title: Surgical stress and the gastrointestinal tract.
abstract: Surgery on any part of the body results in a wide spectrum of alterations in normal body homeostasis. The gastrointestinal tract is extremely sensitive to surgical stress, even at remote locations. It is now evident that the G.I. tract also plays an important role in development of postoperative complications, such as the systemic immune response syndrome and multiple organ failure syndrome. The amount of information available on the cellular and subcellular changes occurring in the gastrointestinal tract after surgical stress is scant. These changes are important since they would act as initiators of tissue damage seen at a later stage, which in turn lead to postoperative complications. This review looks at the information available on the effect of surgical stress on the small intestine, the role of oxygen free radicals in this process, and the changes occurring at the cellular level.
