[A case of digestive occlusion on an endometriosis lesion after treatment by GnRH agonist]

Endometriosis concerns 10% of childbearing age women and frequently affects the digestive tract. We report here the case of a 31-year-old patient presenting a severe occlusive syndrome while being treated with GnRH agonist, within the framework of an in vitro fertilization. The surgical treatment will find a deep endometriosis affecting the sigmoid and colorectal junction and leading to a colorectal resection. These endometriosis lesion recurrences during ovarian stimulation or by GnRH flare up effect is rare and often debated. The surgical treatment of the lesions, before the medically assisted procreation, seems to prevent these complications.
