Brief Summary:
It has been shown that N-methyl-D-aspartate (NMDA) receptor antagonists (such as ketamine) potentiate analgesic drug's efficacy. Polyamines are allosteric modulators of NMDA receptors. In animal studies, polyamine-free diet has shown antinociceptive properties. This research aims at evaluating analgesic properties of polyamine-low diet after laparoscopic cholecystectomy performed in an ambulatory setting.

Primary Outcome Measures :
  1. Pain intensity for the 7 days [ Time Frame: 7 days ]
    Pain intensity is evaluated by the number of tablets of Tramadol taken by the patients

Secondary Outcome Measures :
  1. Pain scores measured on the day of surgery, [ Time Frame: 12 hours ]
    Pain score (numerical scale from 0 to 10) measured in mid-afternoon, resting lying down, coughing and mobilization (from lying to sitting position)

  2. frequency of impeded hospital discharge the day of surgery [ Time Frame: 24 hours ]
    Failure of outpatient care (i.e. the patient cannot leave the hospital the day of surgery)

  3. Each day pain [ Time Frame: 7 days ]
    Pain scores (numerical scale from 0 to 10) assessed daily from J1 ( after surgery) to J7 in mid afternoon , lying at rest position , coughing and mobilization (from lying to sitting position) .

  4. Quality of life [ Time Frame: 7 days ]
    QLQC30 Questionnaire (version 3)

  5. Residual pain [ Time Frame: 30 days ]
    Pain score (numerical scale from 0 to 10)

  6. Blood levels of polyamine [ Time Frame: 2 years ]
    Blood samples are performed the day of surgery and at J7. The dosages will be performed when all patients will be recruited
