Providing information to surgery patients is a form of health-care governed by clearly defined therapeutic and medicolegal rules, and in particular in France by the Act of March 4, 2002 and the Code of Good Practice. The patient's right to information is implemented in a face-to-face consultation, which should be fully codified, and in a specific clinical examination, followed by information regarding the affected organ, pathology, treatment options, possible surgery, and the preconditions, risks and results associated with the procedure. Information should be personalized and as complete as possible, communicating the state of knowledge as validated by scientific societies and medical institutions. State of the art technology (dedicated website, on-line information suites, etc.) is indispensable but needs to be mastered and to adhere to the guidelines of the Council of the National Order of Medicine. Information traceability, the retraction period and proof of content of the information are essential. A signed document delivered in an informative atmosphere optimizes the exercise. Patient information is an ethical and medicolegal obligation, but above all is the expression and demonstration of the health-care potential of the practitioner and our contribution to reducing the information gap, reinforcing the cement holding our society together.
