[Geriatric surgery or geriatrisation of surgical medicine].

In the western industrial nations the proportion of old people (according to WHO definition people over 75 years) has been rising for many years and with it the amount of surgical treatment on this group of the population. High age does not automatically mean a risk too high for surgical treatment. Very often the reasons for this age group being high-risk patients are hospital admission in an advanced stage of illness or complications due to the illness. Old people are biologically younger than they were years ago. Often they express their perfectly understandable wish for suitable treatment. New treatments and strategies in surgery such as minimal-invasive surgery, endoluminal techniques for heart and vascular surgery, fast-track-concepts, anaesthetising techniques like spinal anaesthesia or the use of better controllable narcotics, improves alleviation of pain, quick mobilisation and early oral nutrition contribute to a minimisation of the risk. Age-related multimorbidity defines the risks of major operations and requires an individual weighing up of benefit and risk. The decision for or against an operation must take the elderly patient's wishes into account. The most important aspect is not only to help the people survive but to enable them to participate in life. In this paper we try to give an overview of geriatric surgery with all its aspects relevant to insurance.
