Pierre, a young man with Crohn's disease, regularly needs to undergo a colonoscopy and kept postponing his appointment for this annoying examination. The last one had been done five years ago and it was overdue. In the initial interview it turned out that Pierre's resistance was not related to the examination itself, this takes place under anesthesia, but to the tedious preparation in which one has to drink liters of an unpleasant smelling liquid. He also feared the repetition of an earlier situation when he threw up a few bottles of this fluid and had to start the preparations all over again.

His level of distress while imagining preparing for the colonoscopy at the beginning of the session was extremely high, a 10 on the 0-10 scale. In the application of the Logosynthesis sentences Pierre neutralised a range of perceptual triggers one by one:

- the terrible taste of the saline solution he had to drink.
- the pink colour of the saline solution in the bottles.
- the visual markers on the bottles, which signified how much he had to drink each 15 minutes.  
- the smell of the saline solution in his nose.
- the kinesthetic experience of his stomach feeling like it was going to explode from the fluid.
- the dissociated image of himself vomiting out a wave of the fluid.
- the image of the yellow floor and the white doctor's coat after regaining consciousness.

After these seven rounds Pierre's feet felt warm, and he perceived the colours in the room more intensely. When I asked him to imagine making an appointment and going through the preparations, we had to do one last round on the image of the monitor and the colonoscopy tube in the examination room. Then he said: "I feel tired, now I'm going to sleep while they're doing the procedure." It turned out that the colonoscopy itself was associated with a deep feeling of relaxation as a result of the anesthesia.
