Endometriosis

Endometriosis

Overview

When uterine lining, or endometrium (“metri” means uterus, and “endo” refers to inside lining), is found outside the uterus in the abdominal cavity, this is Endometriosis. Endometriosis will respond to Estrogen and can cause pain with menstrual cycles, pain with sexual intercourse, chronic unrelenting pelvic-back-hip-leg pain, and infertility. Not everyone has every symptom, and some individuals have had pregnancies. The intestinal tract is involved in at least 10-15% of cases, and the urinary tract is involved in 1-2% of cases.

Diagnosis

Endometriosis is a surgical diagnosis. This means it cannot be diagnosed by taking your history, physical examination, blood or urine tests, x-rays, ultrasounds, MRI, or CT scan. The physician needs to look surgically, with laparoscopy. Laparoscopic excision is better since you get a tissue diagnosis, but the surgeon has to at least look. Some lesions may look like they are definitely endometriosis, but it may not be confirmed on pathology. Other lesions are very subtle and not very suggestive of endometriosis, but pathology confirms it to be endometriosis. Therefore, with laparoscopic excision, you get to know what you do and don’t have, and you avoid labeling a patient with a condition they may not have.  The best possible chance for pain relief comes with the surgical removal of all the disease.

If you’ve been told you have endometriosis, please let us know. The only way to be sure is through diagnostic surgery which we can perform as an outpatient procedure.

Treatment

When a physician looks in the abdomen at laparoscopy, and the patient is found to have endometriosis, the doctor can try to destroy the lesions (laser vaporization or burning the lesions with electrical cautery - "fulguration") or the areas of endometriosis can be excised (going around, underneath, and completely removing the tissues that are hurting you). Endometriosis starts out superficial in the lining of the body cavity in the peritoneum. It will then invade deeper into the tissues. 
Endometriosis invades deeper into the tissues than superficial application of laser or electrical energy penetrates. The endometriosis and pain recurs (it actually never left), and the patient ends up with surgery after surgery. Almost all centers that specialize in Endometriosis, in and out of the USA, perform excision. Even after excision, endometriosis, adhesions, and pain can persist and/or recur, and need further treatment later on. Excision gives the best chance for long-term pain relief, and minimizes the need for repeat surgeries. 
Even if the surgeon completely and safely treats the endometriosis lesion with fulguration or laser, they only apply energy to the lesion they see, and they do not account for, and do not treat, the subclinical disease in the tissues beyond the visible perimeter of the lesion. 
With excision we always try to take adequate margins. 

With laparoscopic excision, all areas of suspected endometriosis are excised completely down to normal tissue with adequate margins, and all specimens are sent to Pathology for confirmation. Excision gives the best chance for long-term pain relief, and minimizes the need for repeat surgeries. 

Rationale for Excision

In years past, physicians were taught that it was not worth trying to treat all areas of endometriosis since the ectopic endometrial tissue could be located in visibly normal peritoneum. We now know that these old studies, from open laparotomy, were incorrect. With the exposure, illumination, magnification, and ability to work in close proximity to tissue, all diseased areas can be clearly identified and removed.

We know from pain mapping studies (small laparoscopes place into the abdomen of awake patients under conscious sedation) that pain can be perceived up to 28 mm beyond the visible border of a lesion. Therefore, we excise with 2-3 cm margins wherever possible. From these same pain mapping studies we also know:

  • Implants on the pelvic sidewalls can radiate into the hips and down the legs
  • Implants on the uterosacral ligaments can radiate to the lower back, and cause painful bowel movements and painful intercourse.
  • Implants in the cul de sac (in the back of the pelvis) can refer pain to the rlow back, tailbone, rectum, and cause painful bowel movements and painful intercourse.
  • Implants over the bladder in the front of the pelvis can cause pain with urination, and urinary frequency and urgency
  • Implants on one side of the body can be perceived as pain, in some cases, on the opposite side of the body. Careful attention is paid to the patient's history, but at the time of surgery it is essential to evaluate all areas of the pelvis and treat any abnormal areas. 
  • Excisions are taken from all areas that correlate with the distribution of the patient's pain. 
  • Peritoneal pockets (which cannot be cauterized or vaporized) are associated with pain and endometriosis, and need to be excised
  • Deep nodular implants (which cannot be cauterized or vaporized, especially when adjacent to bowel or ureter) cause significant pain and must be excised
  • Subtle lesions (such as flame-type, clear vesicles, brownish staining) are the most active and painful lesions, are often missed in quick 2-incision laparoscopies, and must be excised.
  • The most common surgical finding of endometriosis is not the disease itself, but the fibrosis and scarring it leaves behind. Adhesions are when 2 structures are stuck together. Normally in surgery, adhesions are simply divided. With endometriosis, there can be endometriosis implants within the scarring. If the adhesions are only divided, then endometriosis is allowed to remain on both sides, and the patient does not get better and ends up with further surgery. Whenever 2 areas are stuck together (uterus and bladder, uterus and rectum, ovary and uterus, and/or ovary and pelvic sidewall) that is the hallmark of invasive endometriosis. It is necessary for the surgeon to come around both sides of the adhesions and take the scarring/adhesions as specimen. 

Therefore, we completely excise all visible disease along with its associated fibrosis, with adequate margins, down to normal tissue. We carefully excise wherever disease is present. To do anything less, will lead to persistent pain and an increased likelihood of multiple surgeries. Because we carefully identify all vital structures (blood vessels, bowel, bladder, ureters), and we work in normal tissues to completely get around the area of disease, we are able to perform this comprehensive surgical approach and keep our patients safe.

Anything other than excision generally LEAVES DISEASE BEHIND.

Endometriosis often implants exceedingly close to, or directly over, vital structures, such as the ureter. Destructive techniques cannot effectively or safely treat this situation.

Frequently Asked Questions About Endometriosis

  1. What is endometriosis?
    Endometriosis is a medical condition where tissue similar to the uterine lining is present outside the uterus in the abdomen, pelvis, or other areas in the body. The uterine lining is called endometrium (“metri” means uterus, and “endo” refers to inside lining). Endometriosis (“endometri” refers to endometrium, “osis” means medical condition). 

  2. What are some symptoms of endometriosis?  
    Endometriosis will respond to the hormone estrogen and can cause pain with menstrual cycles, pain with sexual intercourse, infertility, and unrelenting chronic pelvic, back, hip-and leg pain. Not everyone has every symptom, and some individuals have had pregnancies. Endometriosis is a factor in up to 40% of cases of unexplained infertility.

  3. How common are Intestinal endometriosis and urinary tract endometriosis?
    The intestinal tract is involved in at least 10-15% of cases, and the urinary tract is involved in 1-2% of cases. 

  4. How common is endometriosis?
    Endometriosis effects 10-15% of the female population. 

  5. How is endometriosis diagnosed?
    Endometriosis is a “surgical diagnosis”. This means it cannot be diagnosed by taking your history, physical examination, blood or urine tests, x-rays, ultrasounds, MRI, or CT scan. The physician needs to look surgically, with laparoscopy (”lapar” means abdomen, “scopy” refers to a tube with a light). There are two reasons why endometriosis is a surgical diagnosis: 1) There is no correlation between the symptoms the person is experiencing and whether endometriosis is present and 2) There is no correlation between the severity of the symptoms and the extent of endometriosis present.
