The research procedure is the injection of 20 mL of Ropivacaine solution (vs. saline) to create a paracervical block at the beginning of surgery, while the patient is already under general anesthesia.
This injection will take place 3 minutes before the vaginal incision, via 4 injection points. Injections are made 3 mm deep into the vaginal cul de sac.
Randomization takes place before surgery by vNOTES:
* Experienced group: Local anesthesia with injection of Ropivacaine (20mL of ropivacaine 7.5 mg/mL, i.e. 150mg) and general anesthesia * Control group: Injection of 20mL of placebo (saline) and general anesthesia
In both groups, systematic intraoperative and postoperative analgesia will be identical.
Adult patients aged 18 to 70 inclusive
