Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Changes in the intensity of specific endometriosis symptoms from baseline pre-surgery
Time Frame: Every 3 months in the first 12 months after surgery and every 6 months in the following 12 months

The specific endometriosis symptoms include pelvic pain, dysmenorrhoea, pain at time of ovulation, dyspareunia to be assessed with a 10-cm visual analogue scale (VAS).

Other symptoms (Amenorrhea, menorrhagia, metrorrhagia, Global GI symptoms & urinary discomfort,) will be assessed by oral enquiry to the patients based on numerical scale from 0 to 10 (0 being the best and 10 the worst status).

Every 3 months in the first 12 months after surgery and every 6 months in the following 12 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Recurrence rate of specific endometriosis symptoms
Time Frame: At 12 months and 24 months
Recurrence rate of specific endometriosis symptoms in the group of patients with mild or null symptoms score following surgery and Diphereline treatment.
At 12 months and 24 months
Change during the study period in symptom(s) having the highest intensity at baseline
Time Frame: 24 months
The highest intensity at baseline is defined as the symptom with the highest score on pre-surgery assessment.
24 months
Rate of pregnancy in subjects
Time Frame: At 12 months and 24 months
At 12 months and 24 months
Abdominal pain-free interval
Time Frame: Every 3 months in the first 12 months after surgery and every 6 months in the following 12 months
Assessed using a visual analogue scale (VAS).
Every 3 months in the first 12 months after surgery and every 6 months in the following 12 months
Disease profile of DIE patients treated by Diphereline and by duration of treatment.
Time Frame: 24 months
The disease profile (size of the lesion, locations etc…) will be detailed in each group of treatment duration by descriptive statistics.
24 months
