Brief Summary
Myofascial pains are frequently found during the clinical examination of the patients presenting a painful chronic syndrome of the pelvis or the perineum. If the physiopathology of this component of the pain characterized by triggerpoints found in the clinical examination, remains uncertain; its coverage contributes to the improvement of the global pain of the patient. The physiotherapy can be useful but when it is not useful, we proposed injections of triggerpoints by local anesthetics. The injections of botulinum toxin on these triggerpoints have a legitimacy (action on the muscular cramp and action on the afferent fibers) but are they superior to the injections of local anesthetics of triggerpoints? The literature remains poor on the subject, justifying this randomized double-blind protocol comparing the efficacy of the botulinum toxin associated with a local anesthetic versus local anesthetic alone with a main criterion of evaluation in 2 months and a monthly follow-up as long as the patient remains improved and maximum in 6 months.

Outcome Measures
Primary Outcomes (1)
Evolution of the PGI-I (Patient Global Impression of Improvement)
The main objective is to evaluate the efficacy of injection of botulinum toxin A associated with ropivacaïne versus ropivacaïne alone on the global suffering of chronic myofascial pelviperineal syndromes two month after the injection. The success will be defined as an improvement of the PGI-I corresponding to the first 2 levels.
2 month
Secondary Outcomes (3)
Evaluation of pain on digital scale (EN)
6 month
To assess the changing parameters of quality of life: global improvement score / treatment satisfaction assessed by digital scale, international pain scales (MPI, QDSA, QCD) / Beck and HAD score
6 month
To assess the evolution of analgesics consumption (score MQS)
6 month

Eligibility Criteria
You may qualify if:
- Age \> 18 years
- Patient presenting a "dysfunctional" pain of the pelvis or the perineum (without lesional pathology justifying a specific treatment) by an endopelvic touch
- Pain evolving since at least 6 months and persisting in spite of the analgesic treatments and the physiotherapy
- Patient presenting to the clinical examination one or several active triggerpoints found on the internal obturating muscles and/or elevators of the anus, with a maximum of 10 triggerpoints on the whole body.
- Signed informed consent
- Subjects affiliated with an appropriate social security system
You may not qualify if:
- Patients with bleeding risk and anticoagulant therapy
- Intolerance of botulinum toxin A, ropivacaïne and nitrous oxide
- Injection of botulinum toxin in any place whatsoever in the previous 3 months
- Pregnancy and breast feeding
- Antibiotic treatment by aminoglycosides
- Recent anti-inflammatory treatment
- Severe myasthenia
- Lambert-Eaton syndrome
- Patients with neurological disorders, dysphagia, food choking or inhalation pneumonia
- Beck score \> 16
- Patients having an average of the maximal pains of the previous week lower than 4
