[Operating position in colorectal surgery. The importance of the basics].

Intra-operative positioning in colorectal surgery is very important from three points of view: the proper surgical approach and exposure, adequate anaesthetic requirements with maintenance of the airway, and the potential complications related to the position. In the present study, we analyse the indications, positioning, advantages and disadvantages of each operative position, their potential complications and how to avoid them. These complications can be of a diverse nature, the most common being injuries related to stretching or compression of peripheral nerves, followed by thromboembolic, haemodynamic, and ischaemic or compartmental syndromes related to ischaemia-reperfusion after a long time in the Trendelenburg position.
