The aim of this study is to evaluate whether a local perianal block performed during a proctological intervention can reduce the postoperative pain.~All patients will undergo surgery under general or spinal anesthesia. At the end of the surgery, the surgeon will perform a perianal block using the local anesthetic or the placebo upon randomisation. The experimental group will receive a local anesthetics and the control group a normal saline injection. All injections will be perianal, peripheral to the external anal sphincter.
