Prehabilitation in elective surgical interventions - what must the general and abdominal surgeon know.

Objectives: For years, many efforts have been invested to prepare patients, in particular, those with reduced physical and psychic status, much better to provide and finally achieve better outocme if there is time available to provide several beneficial measures.

Methods: Therefore, the objective was to illustrate the concept and various single elements of a complex prehabilitation concept based on (i) selective references from the medical literature and (ii) own clinical experiences from clinical practice in general and abdominal surgery.

Results: Prehabiliation can be considered the solution of the efforts to improve preoperative status for patients in a disadvantageous status for almost all types of surgery and all other operative and/or interventional procedures. It is the targeted process to improve individual functionality and organ function before a planned (elective) surgical intervention; P. comprises basically nutritional, physical and psychological measures; P. focusses especially onto the elderly, frail and malnourished patients before a planned surgical intervention; the overall aim is to significantly improve final outcome characterized by shorter length of stay, lower complication rate and mortality as well as cost efficiency; P. is especially important in cancer surgery, in which the beneficial effects can be particularly implemented; P. programs and/or "Standard Operating Protocols" (SOP) may help to establish and materialize its single aspects and enhanced recovery after surgery (ERAS). There is still further potential to reliably establish and to utilize the options of prehabilitation measures as listed above.

Conclusions: Prehabiliation is an indispensable aspect in today's preparation for elective surgery, which needs to become obligatory part of the preparation measures to planned surgical interventions, which can further contribute to a better final outcome and ERAS as well as, in addtion, needs to be further developed and accomplished.
