Endometriosis is a common gynaecological condition affecting approximately 10% of women of reproductive age (Ozkan 2008). Common symptoms are dysmenorrhoea, pelvic pain, infertility or a pelvic mass. Diagnosis by laparoscopy or laparotomy enables identification of the location, extent and severity of the disease. Surgery may include removal (excision) or destruction (ablation) of endometriotic tissue, division of adhesions and removal of endometriotic cysts. Laparoscopic excision or ablation of endometriosis has been shown to be effective in the management of pain in mild to moderate endometriosis. Adjunctive medical treatment pre or post-operatively may prolong the symptom-free interval.
