Summary
MEDICAL treatment of endometriosis is suitable as primary therapy in young patients with minimal disease confirmed by laparoscopy. Medical treatment consists of simple analgesia, treatment with combined oestrogen/progestogen preparations, or progestogen therapy alone. Danazol therapy is now widely used in a dose of about 400 mgs daily for a minimum of six months.
The success rate in terms of pregnancy is about 60–70%, but when other associated factors are included such as oligospermia or pelvic inflammatory disease, the success rate falls to between 35–56%.
The pregnancy rate with medical treatment is more successful with moderate disease than extensive disease, and the recurrence rate after cessation of therapy varies from 17% after one year to 50% after nine years.
The side-effects of drug therapy are dose related and include symptoms due to the androgenic effects of the drug, symptoms due to pituitary-gonadal inhibition, generalised systemic effects and disorders in blood chemistry.
