What is the study measuring?
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
