High recurrence rates have been reported in women treated for endometriosis despite advances in medical and surgical treatments improving both fertility and symptoms. It should therefore be considered a chronic disorder. In this particular setting, the main objectives for practitioners are to limit disease progression, recurrence and to improve quality of life (QOL). Previous studies have demonstrated a relation between an increase in pain intensity and a decrease in QOL. However, visual analogue scales to measure general well-being are insufficient to quantify the impact of endometriosis on QOL. Several generic questionnaires, mainly the SF-36, are available in various languages but are not specifically for women with endometriosis. Some specific questionnaires are available but have been validated in English populations for the most part rending comparison between countries difficult. Despite these limits, QOL should be systematically monitored over time by a validated questionnaire for this chronic disorder.
