Endometriosis (redirected from Endometreosis)

endometriosis (ĕn'dəmē'trē-ō`sĭs), a condition in which small pieces of the endometrium (the lining of the uterus) migrate to other places in the pelvic area. The endometrial fragments may move to the fallopian tubes, ovaries, or other pelvic structures (e.g., the bladder or rectum). The migrated tissue retains its character and changes with the fluctuations of the menstrual cycle, bleeding at the time of menstruation. The blood becomes trapped in cysts that can grow from the size of a pinhead to the size of a grapefruit. Symptoms of endometriosis can be absent or can include painful menstruation, severe abdominal or low back pain, painful intercourse, and rectal bleeding at the time of menstruation. Symptoms often disappear with pregnancy, but 30%–40% of women who have endometriosis are infertile.

The cause of endometriosis is unknown. One hypothesis is that the endometrial fragments move back up through the fallopian tubes rather than leaving the body with the menstrual flow. Diagnosis is by pelvic examination or laparoscopy. Treatment, which depends on the severity of the disease, may include a course of oral contraceptives, or danazol if the patient is trying to conceive. In severe cases surgical removal of the cysts or hysterectomy may be performed.

endometriosis

Disorder of the female reproductive system in which endometrium (uterine lining) grows in an abnormal location because some endometrial fragments traverse the fallopian tubes into the abdominal cavity and become embedded on structures there, usually the ovaries, rather than exiting the uterus via the vagina (during menstruation). Symptoms include pain on menstruation, sexual intercourse, defecation, and/or urination; heavy menstrual flow; blood in the urine; and infertility. Diagnosis is best made by laparoscopy. Treatment includes surgery and hormones to suppress ovulation for six to nine months.

Endometriosis 

a gynecological disorder characterized by the tumorlike growth in various organs of endometrioid tissue that structurally and functionally resembles the uterine mucous membrane, or endometrium. The disease generally develops in women between the ages of 30 and 50. Its cause has not been established. One theory is that the condition is caused by the migration of endometrial tissue through blood vessels and the uterine tubes to pelvic organs and other parts of the body. A distinction is made between endometriosis interna (endometrial growths in internal genital organs—most often the uterus and ovaries) and endometriosis externa (growths outside the uterus—in the umbilicus, perineum, intestine, and elsewhere).

Endometriosis is characterized by cyclical changes in the endometrioid masses and by hemorrhages in focuses of the growths during menstruation. Pain is felt before and during menstruation. Endometriosis of the uterus, also known as adenomyosis, intensifies and prolongs menstrual bleeding. The condition may result in sterility. Endometriosis is usually treated by hormonal preparations and uterine agents; some cases require surgery or radiotherapy.
