Objective: To review current understanding of endometriosis. Method: A
review of etiology, pathogenesis, relationship with. infertility, med
ical and surgical treatment. Results: It is likely that endometriosis
occurs in most women at some stage in their reproductive years. Exposu
re to menstruation and estrogen are important etiologically. Current e
vidence suggests that implantation of menstrual endometrium is the com
monest mechanism of pathogenesis. Clinical symptoms and signs are impo
rtant in the diagnosis while laparoscopy remains the prime diagnostic
technique. Treatment is not indicated for infertility but is for sympt
oms. Danazol and progestogens represent the best first-line therapy al
though gonadotropin-releasing hormone agonists are appropriate if econ
omically justifiable. Both open and laparoscopic surgery are important
especially in reconstructive work. The value of laser ablation in the
treatment of infertility is unknown but it is effective in pain. The
disease should be regarded as a recurrent problem and treatment strate
gies designed appropriately. Conclusion: Endometriosis still represent
s an intellectual and-therapeutic challenge but successful treatment i
s possible especially if it is individualized for each patient.
