Pilot study to evaluate the efficacy of endosampler as a tool for diagnosing endometriosis in comparison with endometrial currettage to identify endometrial nerve fibers by staining the obtained endometrial biopsies with Polyclonal rabbit anti-protein gene product (PGP9.5) of unmyelinated endometrial nerve fibres

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Two interventions will be done:
1- endometrial biopsy using MedGyn EndoSampler(Distributed by IPAS. Manufactured by MedGYn).
2-endometrial biopsy using curetting
The Endosampler:
Is a sterile disposable curette for sampling endometrium aids to obtain differentiated endometrial tissue without anaesthesia. Except for rare instances it does not need cervical block. It has 3mm cannula with sharp sluts to ensure better sampling which attached to 10 mm syringe.
This pilot study will be conducted by recruiting 20 women known to have endometriosis but not recently on treatment for endometriosis. Two questioners will be filled; one by the woman herself stating her past medical history and cycle history; other one will be filled by treating doctor documenting woman’s medical history, clinical and laboratory findings. After obtaining an informed consent from the woman, an endometrial biopsies will be obtained by endometrial curettage and endosampler in theater during laparoscopy and D&C usually within one month after obtaining consent. The two biopsies will be stained by PGP9.5 to look for endometrial nerve fibers. A comparison between the two biopsies will be done to see if endosampler is successful as endometrial curettage in identifying these nerve fibers.

one week
Primary outcome [2] 1458 0
Explore the ability of Endosampler in picking up these endometrial nerve fiber in comparison to endometrial curettage
Timepoint [2] 1458 0
one week. The staining will be done in one week time after both biopcies are taken
Secondary outcome [1] 2610 0
Two questioners will be filled at the time of first interview at the clinic; one by the woman herself stating her past medical history and cycle history; other one will be filled by treating doctor documenting woman’s medical history, clinical and laboratory findings.
Timepoint [1] 2610 0
Both questionnaires will take 30 minutes to fill. A qualitative analysis will be done after finishing the study. The expected time between the first interview and the interventions is one month.

Summary
Brief summary
A research study into the gynaecological disease called endometriosis. Endometriosis affects 10 -15% of reproductive women. It can cause painful periods and painful intercourse, infertility and irregular bleeding. The cause of the disease is still unknown and the diagnosis of endometriosis is only possible with surgery. Women who are known to have endometriosis and those whose symptoms suggest that they may have endometriosis are being invited to participate in our study.
The objective of our study is to investigate whether a device called Endosampler can be used to diagnose endometriosis by picking up small nerve fibres in the lining of the womb .Our preliminary studies suggest that these nerve fibres play a role in pain generation associated with endometriosis
