Surgery of endometriosis

Progressive and almost always defined as endometrial by the presence of endometrium outside the uterine cavity

What is endometriosis?

It is a progressive and almost always mild disease defined by the presence of endometrium outside the uterine cavity. The endometrium is normally the inner lining of the uterus that grows during the cycle under the effect of female hormones. In the absence of pregnancy, the endometrium detaches from the uterus causing menstruation. In some patients, endometrium islets will implant outside the uterus into the abdominal cavity on the peritoneum, the surface of the uterus, the fallopian tubes, the ovaries, the bowel or bladder.

These implants will under the effect of female hormones, grow and then bleed which causes an inflammation of the affected organs, altering their function and creating pain. Endometriosis lesions are organised as implants, nodules or cysts.

A disease that comes from menstruation? Yes, partially.

During menstruation, most of the blood flows from the uterus into the vagina. However, there is also a blood flow from the uterus to the abdominal cavity through the tubes. This tubal reflux of menstrual blood is physiological, however in some patients, the endometrium which arrives in the abdominal cavity will, instead of being cleaned successfully take root and survive, thus creating endometriosis.

What are the main symptoms of endometriosis ?

Sometimes endometriosis is discovered incidentally during a laparoscopy performed for another reason. Otherwise, infertility and pain are the two major symptoms of endometriosis. A cyclical and premenstrual experience of pain is very suggestive of endometriosis.

The main possible symptoms are:

pain during menstruation (dysmenorrhea)
pain during sexual intercourse (dyspareunia)
variable pelvic pain
pain during exemption (in case of deep endometriosis located on the rectum)
pain during urination (in case of deep endometriosis located on the bladder)
heavy menstruation

What is the treatment for endometriosis ?

The goal of treatment is twofold:

to relieve pain
to preserve fertility

The treatment of endometriosis includes drug treatments and surgery by laparoscopy.

Analgesics are used to relieve pain.
Hormonal treatments are prescribed to slow the progression of the disease. They can sometimes be enough to soothe pain and reverse the disease at least temporarily. However, in cases of associated infertility, personalised care of the couple is offered (surgery, insemination, IVF …).
Surgery is particularly indicated in patients with painful endometriosis. A very large majority of patients noted a positive effect on pain after surgery.

Key points of endometriosis surgery

Surgical treatment of endometriosis can sometimes be very delicate and absolutely must be performed by a qualified surgeon. Indeed, an incomplete initial or poorly performed surgery may cause persistent or worsening symptoms and greatly complicates any new surgery.

A careful clinical examination and imaging examinations (pelvic ultrasound and M.R.I) are useful before surgery, to establish a precise mapping of the lesions.

The goal of surgery is to remove most of the endometriosis lesions while leaving the affected and surrounding organs intact.

Moreover, as this surgery often involves women of childbearing age, it is crucial to preserve the reproductive potential of the patient as far as this is at all possible. For example, in cases of ovarian endometriotic cysts, removal of the cyst can cause a significant decrease in the ovarian reserve, and therefore we must be very careful with this procedure, especially if the patient wishes to conceive.

Digestive endometriosis

When endometriosis reaches the wall of the colon or rectum, there are two possible approaches:

The first option is used when the endometriosis only affects a superficial part of the wall of the intestine and the lesion can be removed by shaving the lining of the affected organ: this is called the “shaving” technique. The complication rate is low and the results in terms of pain and fertility are good.
The second option is used when the lesion is embedded deep into the wall of the organ. The shaving technique would almost certainly leave some disease behind. In this case a more radical treatment (see images opposite) is selected: after removing the diseased part of the colon or rectum, an anastomosis is performed, that is to say, a new connection between the two parts of the intestine that are healthy. This procedure is only proposed to selected patients because it can certainly offer a significant improvement in the patient’s quality of life but, it also comes with a high risk of complications.

Urinary endometriosis

Regarding endometriosis reaching the bladder wall, either the shaving technique can be performed, or a partial opening of the bladder can be made to remove the entire lesion. The bladder is then sutured, and generally heals very well.

If the lesion is very close to the ureters (the small pipes leading urine from the kidneys to the bladder), the procedure carries a higher risk of urinary complications. Pre- and intraoperative urological opinion may be necessary.

Thus, any surgery on the bowel or ureters requires close collaboration between the gynaecologist surgeon and the surgeons in the relevant specialty.
