Clinical characteristics and location of lesions in patients with deep infiltrating endometriosis using the revised Enzian classification

Abstract

Objective:To describe the clinical characteristics and location of lesions in patients with deeply infiltrating endometriosis using the revised Enzian (rEnzian) classification.Material and Methods:The clinical records of 60 patients undergoing laparoscopy for deeply infiltrating endometriosis at Hospital Civil de Culiacán, Sinaloa and Hospital San Javier, Jalisco, Mexico, were reviewed. Age, body mass index (BMI), number of pregnancies, childbearing, previous abortions, laparoscopic suggestion (pelvic pain, bleeding, infertility), and size and location of the lesions were assessed according to the rEnzian classification.Results:The mean age of the patients was 30.5 years. The mean BMI was 25.6 kg/m2. Sixty-eight percent were nulliparous and 13% had at least one birth. Eighty-five percent had pelvic pain and 8.3% had infertility. Seventy percent (n=42) of the women had ovarian endometriomas (middle compartment); uterosacral and the torus uterinus ligaments were affected in 23.3%, rectum and sigmoid colon in 35% (posterior compartment), and the appendix and small intestine in 3.3%. According to the rEnzian classification, the most affected compartment was C2 (rectum and sigmoid colon with 1-3 cm lesions).Conclusion:Pelvic pain was the main symptom of patients with deeply infiltrating endometriosis, mainly in nulliparous women. According to the rEnzian classification, the C2 compartment was the most affected (rectum and sigmoid colon).
