Description of intervention(s) / exposure
Placentas of women with endometriosis will be morphologically evaluated after delivery The analysis will be held in accordance with the placental classification system defined by G Turowski , L N Berge, L B Helgadottir et al., 2012;33(12):1026-35. This system is clinically oriented, unifying and simple placental pathology classification defining mainly nine major diagnostic categories including normal placenta.
Clinical Diagnostic categories are listed below:
1.Placenta with normal morphology,according to gestational age
2. Placenta with chorioamnionitis
3. Placenta with villitis and intervillositis
4. Placenta with maternal circulatory disorders
(decidual vasculopathy)
5. Placenta with fetal circulatory disorders
6. Placenta with delayed villous maturation
7. Placenta with findings, suggestive of genetic aberration
8. Placenta with implantation disorders
9. Placenta with other lesions
Each clinical situation has major defining characteristics defined by the authors.
The placentas will be transported to Pathology Department in the same hospital as soon as delivered. The specimens will be fixed and stored until the histopathological examination.
Each patient will be questioned about demographic variables but also antenatal problems such as antenatal bleeding in any trimester, placenta previa, small for gestational age, diabetes mellitus etc. But also, each patient will be questioned about the diagnostic procedures held for endometriosis, the stage of endometriosis and the time to pregnancy after the operation etc. The questionnaires for each patient will be filled by the gynecologist by the interview with the patient. A ten minute questionnaire will be held for this purpose.

Outcomes
Primary outcome [1] 326305 0
Establishment of any distortion in placental histopathology from normal in placentas of women with endometriosis.
The morphological evaluation of placentas of women with endometriosis, who delivered after 20th week of pregnancy will be held in accordance with the classification system defined by Turowski G. et al., (A new, clinically oriented, unifying and simple placental classification system, Placenta 2012 Dec;33(12):1026-35. doi: 10.1016/j.placenta.2012.10.002.).
Timepoint [1] 326305 0
within 10 days after placental removal in C-section for each patient
Secondary outcome [1] 403310 0
Determination of antenatal complications in pregnant women with endometriosis by a questionnaire which is designed for this study. The questionnaire consists of adverse perinatal outcomes such as antenatal bleeding, preeclampsia, preterm deliery etc. which have been recently correlated with endometriosis in the literature.
Timepoint [1] 403310 0
The 10 minute questionnaire will be held at the last visit before delivery

Statistical methods / analysis
This is the first study aims to evaluate histo-pathological properties of placentas of women with endometriosis. This is why, a power analysis can not be held for determination of the study population. The authors aim to define the distorted histo-pathological properties of those placentas to guide further research in this field of research.
