[Physical and mental strain on the surgeon during minimally invasive surgery].

Minimally invasive surgery (MIS) is in theory more physically and mentally demanding than open surgery. This aspect is due to the inherent limits of MIS. The implementation of high-technological operating rooms and the development of ergonomically more useful instruments have not been documented scientifically, nor has the question of whether or not MIS is a contributing problem in itself in the surgeon's work been documented. There is a need for clinical investigations with establishment of methodological models of the ergonomics in MIS.
