[Day surgery in a multidisciplinary breast unit].

The most recent studies on breast surgery have led us to radio-guided surgery which enables us to identify the sentinel lymph node and thus to remove just a single lymph node. As a result, we are moving in the direction of an increasingly conservative surgical technique which may be carried out in the day surgery setting. This kind of surgery requires both an extremely accurate and prompt diagnosis and a multidisciplinary breast unit, inasmuch as only the collaboration and teamwork of highly qualified staff are capable of furnishing a rapid, accurate diagnosis; in addition, during the operation it may be necessary to perform x-rays or ultrasonography on the surgical specimen. Obviously, nuclear medicine is essential for radio-guided surgery. We report here on our experience with 36,000 women with 1,147 carcinomas whose diameters were less than or equal to 2 cm in 78.64% of the cases, with the possibility of performing conservative surgery in such cases. Moreover, by way of confirmation of the good diagnostic accuracy, we report our findings in 954 lesions operated on under local anaesthesia, because they were presumed to be most probably or definitely benign, but which tended to increase in volume. During the final histological examination only 10 of these 954 lesions turned out to be malignant, with only a 1.05% incidence of diagnostic error.
