Endometriosis is a frequent pathology with an estimated prevalence of 10% of women of childbearing age. There is no exact correspondence between the symptoms described by the patients and the severity of the lesions, which makes clinical diagnosis difficult. It therefore seems important to improve the complementary examinations available to make the diagnosis more precise and to better study the effectiveness of the treatments implemented. The clinical examination and per-surgical findings of patients with deep pelvic endometriosis show a clear decrease in the mobility of the pelvic organs in relation to each other, but few studies have looked at this mobility, which could however have an implication in explaining the pathophysiology of the disease and the symptomatology of the patients, as well as in the detection of lesions preoperatively. The persistence of hypo-mobility could also help to understand treatment failures.
