Which of the following treatments for endometriosis is classified as surgical?

The treatment option classified as surgical for endometriosis is laparoscopy with ablation. This procedure involves minimally invasive surgery where a camera is inserted into the abdominal cavity to visualize and treat endometrial tissue that has grown outside the uterus. During laparoscopy, abnormal tissue can be excised or ablated, which can significantly alleviate pain, reduce the extent of the disease, and potentially improve fertility outcomes.

Other treatments for endometriosis mentioned, such as the use of NSAIDs, combination oral contraceptive pills (OCPs), and danazol therapy, are considered medical therapies and do not involve surgical intervention. NSAIDs primarily manage pain symptoms, while combination OCPs may help regulate menstrual cycles and reduce endometrial tissue but do not remove it. Danazol, an androgenic medication, helps to suppress endometriosis-related pain by creating a pseudo-menopausal state but is also not surgical in nature. Therefore, laparoscopy with ablation is distinctly identified as a surgical treatment option.
