Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Efficacy

evaluate the efficacy of posterior perineal block performed under neurostimulation on pain 1 month after local anesthetic infiltration in the treatment of chronic idiopathic ano-perineal pain.

Secondary objectives 5

  1. The rate of maintenance at 3 months of a positive response to the first infiltration
  2. The pain-free rate at 1 month after the first infiltration
  3. Evolution of quality of life and pain impact between inclusion and one month after the first infiltration
  4. Changes in anxiety and depressive disorders associated with pain between inclusion and one month after the first infiltration
  5. The evolution of symptoms related to central sensitization (both somatic and emotional) between inclusion and one month after the first infiltration

  1. Patient 18 years of age or older
  2. Express consent to participate in the study
  3. Affiliated or beneficiary of a social security plan
  4. Presenting chronic idiopathic ano-perineal pain
  5. Normal MRI or no pathology explaining pain
  6. Resistance to “standard” 1st-line medical treatment (1 or 2 analgesics and/or NSAIDs and/or local topicals).

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. Comparison between the two treatment arms (lidocaine versus saline) of the rate of patients with a reduction of at least 3 points on a visual analog pain scale (VAS) between inclusion and 1 month after the first injection.

Secondary endpoints 5

  1. Maintenance of positive response at 3 months, defined as a reduction of at least 3 VAS pain score points (compared with inclusion) 3 months after infiltration.
  2. Percentage of patients with a VAS score equal to 0 at 1 month after the first infiltration
  3. Delta of the score on question 9 of the "modified" Concise Pain Questionnaire (CPQ) (French version of the Brief Pain Inventory) concerning the impact of pain
  4. Delta of scores A (anxiety dimension) and D (depression dimension) on the HAD scale
  5. Delta of the score for part A of the French version of the CSI central sensitization score
