Laparoscopy is useful for diagnosing and treating endometriosis. There are different surgical options for treating endometriosis including ablation using laser or electrocautery to destroy tissue, or excision to remove it. Excision is preferred for endometriomas and deeply infiltrating lesions to reduce risk of recurrence and improve pain. Additional procedures like presacral neurectomy or appendectomy may help in some cases. Complete excision of lesions along with adjunctive measures provides the best chance for long-term pain relief, but requires an expert surgical team given the challenges of deeply infiltrating disease.
