Oocyte competence in in vitro fertilization and intracytoplasmic sperm injection patients suffering from endometriosis and its possible association with subsequent treatment outcome: a matched case-control study.

Introduction: Endometriosis affects up to 15% of women of reproductive age. There is an obvious lack of studies dealing with morphological parameters of oocyte morphology in endometriosis patients in assisted reproduction. One aim of the study is to describe oocyte morphology in patients undergoing intracytoplasmic sperm injection suffering from endometriosis.

Preoperative planning of surgery for deeply infiltrating endometriosis using the ENZIAN classification.

Objective: To use the ENZIAN classification for preoperative estimation of laparoscopic operating time in patients with deeply infiltrating endometriosis (DIE).

Study Design: Retrospective study of women with DIE (n=151) who underwent laparoscopic surgery.

Results: 151 of 470 patients had DIE (n=205 lesions) exclusively in compartments A (rectovaginal septum, vagina), B (sacrouterine ligament to the pelvic wall) and C (rectum, sigmoid colon).

Comparison of revised American Fertility Society and ENZIAN staging: a critical evaluation of classifications of endometriosis on the basis of our patient population.

Objective: To develop a classification that takes deep infiltrating endometriosis into account, the ENZIAN score was introduced. The ENZIAN classification supplements the revised American Fertility Society (AFS) score with regard to the description of deep infiltrating endometriosis, retroperitoneal structures, and other organs. The null hypothesis was that classifying a lesion by the revised AFS as well as the ENZIAN system is not meaningful, because the two systems express different locations.

The role of three-dimensional volume measurement in diagnosing endometrial cancer in patients with postmenopausal bleeding.

Objective: To evaluate the role of three-dimensional transvaginal ultrasound in diagnosing endometrial cancer in patients with history of postmenopausal bleeding and compare its effectiveness with two-dimensional ultrasound.

Methods: Transvaginal ultrasound examinations, diagnostic hysteroscopy with subsequent curettage, and/or hysterectomy were performed in 213 consecutive patients with a history of postmenopausal bleeding. The results of the ultrasonographic examinations were compared with the diagnoses on the basis of histologic examination.
