Objective: In our previous study, 119 patients with histologically confirmed endometriosis underwent a 'three-step' therapy between 1987 and 1989, where surgical removal of endometriosis was followed by a 6 month treatment with 3 x 300 microgram buserelinacetate daily intranasally and a second look laparoscopy or laparotomy with removal of residuals. Long-term follow-up data in respect of recurrence of symptoms and pregnancy outcome were investigated.
Study-design: Long-term follow-up data of 42 out of 119 treated patients on the post-treatment effect were obtained using a special questionnaire. Recurrence of dysmenorrhea, dyspareunia and pelvic pain was defined as recurrence of disease. The follow-up period was up to 98 months with a median time of 82.5 months.
Results: Out of the 42 patients, 23 complained of infertility. Fourteen out of these 23 patients became pregnant during the follow-up period, resulting in 23 pregnancies with 18 newborns, 4 miscarriages and one ectopic pregnancy. Ten patients conceived spontaneously, stimulation program became necessary in the rest of patients. Twenty-eight of the 42 patients complained recurrence of symptoms with median first onset at 10.7 months. Improvement on quality of life and subjective conditions were reported by 30 patients.
Conclusions: Our study suggests that the 'three-step' therapy of endometriosis with GnRH-agonist buserelinacetate leads to a significant improvement on the quality of life and well being in the majority of the patients and to a high pregnancy rate. This treatment represents a favourable approach in the management of endometriosis.
