|Deep Infiltrating Endometriosis (DIE)||
Drug: Triptorelin Acetate 3.75mg intramuscular injection
Triptorelin Acetate is a Gonadotrophin Releasing Hormone agonist (GnRHa).
Triptorelin acetate for injection 3.75mg administered as described in the patient information sheet approved in China: one intramuscular injection of the product repeated every 4 weeks.
Other Name: Diphereline 3.75mg intramuscular injection
- 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).
- 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.
- 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.
- Rate of pregnancy in subjects [ Time Frame: 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).
- 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.
