Nearly one-third of the women having endometriosis have no symptoms other than infertility. The others have varying degrees of symptoms, depending on the stage of the disease. Oddly enough, the early stages or milder forms are frequently more painful than the later stages. We believe this is because the young endometrial tissue liberates spasm-causing prostaglandins, whereas the older endometrial tissue simply burns out and turns into inactive scar tissue. The most common symptoms associated with endometriosis are pain and infertility, however, premenstrual spotting, urinary urgency, rectal bleeding, painful urination, bloody cough, and skin nodules may also be noted.
Careful evaluation is necessary to ensure accurate diagnosis.
Table 17-l gives a profile of the endometriosis patient and tells where the implants, which can be found anywhere in the body, are most frequently located. Any complaint related to menses suggests endometriosis. Occasionally while doing the pelvic examination I can feel the telltale beading on the outside of the reproductive organs. The only definitive diagnostic procedure for endometriosis, however, is a direct look inside the abdominal cavity and a biopsy of the tissue. Since laparoscopy requires general anesthesia, I try to rule out all other male and female fertility factors before performing it.
