Endometriosis is a common condition affecting 10% of women. It is characterized by the presence of ectopic endometrial cells. This pathology most frequently develops in the ovaries, utero-sacral ligaments and pelvic peritoneum, but also in the recto-sigmoid. Rarely, these lesions are found outside the pelvis, and even more exceptionally in the abdominal wall (in 0.03 to 1% of cases).

Cryotherapy has already been used for many years to treat soft tissue tumors (kidney and prostate tumors). It has also been successfully used by interventional radiologists to treat parietal desmoid tumors. After discussions with radiologists, given the similarity of location and extension of wall endometriosis lesions with desmoid tumours, the successes observed, and the scarcity of studies in the literature, it seemed appropriate to the investigators to study this new therapy.

The aim of this study was to investigate the efficacy of cryotherapy on parietal endometriosis lesions.
