Shots are required after abdominal wall endometriosis surgery, usually GnRH shots, or treprostinil acetate for injection, under the direction of a physician. The injection after abdominal wall endometriosis is given to suppress the function of the ovaries to achieve an artificial pseudo-menopausal state. In the artificial pseudo-menopausal state, all the hormone levels secreted by the ovaries are in an extremely low state, which in turn inhibits the growth of the endometrium, thus preventing the recurrence of endometriosis. For postoperative endometriosis patients, if there are residual lesions, treatment with injections can enhance the efficacy of postoperative treatment as the residual tiny lesions can be atrophied and necrotic. It is generally recommended that after undergoing surgical treatment for endometriosis, supplemental treatment with injectable treprostinil acetate injection is administered, which in turn achieves a better inhibition of endometriosis, or achieves a delayed recurrence effect.
