[Perineal regional anaesthesia: indications in gynaecologic and proctologic surgery and in obstetric].

Perineal and proctologic surgery is well known as very painful. The apparition of new specific needles, long acting and less toxic local anaesthetics and neurostimulation allowed reconsidering some old forgotten techniques. Those blocks appear really useful to optimize multimodal postoperative analgesia and postoperative rehabilitation. After anatomic review, authors describe perineal regional anaesthesia and discuss about main indications and advantages, in the eyes of their experience and bibliographic review.
