Routine clinical examination is not sufficient for diagnosing and locating deeply infiltrating endometriosis.

Résumé vulgarisé

STUDY OBJECTIVE: To determine whether routine clinical examination is sufficient for the diagnosis and establishing the location of deeply infiltrating endometriosis (DIE). DESIGN: Retrospective analysis (Canadian Task Force classification II-2). SETTING: University-affiliated hospital. Patients. One hundred sixty women with histologically proved deeply infiltrating endometriosis. MEASUREMENTS AND MAIN RESULTS: Speculum examination allowed endometriotic lesions to be viewed in only 14.4% (23) of patients, and a classic, painful, spheric nodule was palpated in only 43.1% (69). Results of routine clinical examination varied significantly with location of DIE. Whereas a nodule was found in 80.0% (24) of patients with vaginal endometriosis, this rate dropped to only 35.3% (6) and 33.3% (34) in those with DIE of the digestive tract and uterosacral ligaments, respectively (p <0.0001). CONCLUSION: High locations of DIE lesions at the level of uterosacral ligaments, bottom of the pouch of Douglas, and upper one-third of the posterior vaginal wall explain why results of routine clinical examination are so poor. The term -'deep endometriosis infiltrating the rectovaginal septum-' is generally incorrect in the true anatomic sense.
