Painful periods and endometriosis

I will have a patient come for help who has had a long history of painful cramping with her period.  Occasionally these patients will have had a hysterectomy performed at an early age because none of the medical therapies have worked to control her pain.  Painful periods can have many causes.  I would like to discuss one of the most common - Endometriosis.

Endometriosis pain typically starts one to two days prior to bleeding.  In the beginning stages, endometriosis is usually cyclical (it comes and goes with the menstrual cycle).  At later stages if the endometriosis becomes invasive, there can be dense fibrosis or scarring that may give the pain a more constant character.  Approximately 10% of endometriosis is invasive.  This means that it grows deeper in the tissue to which it is attached.  Common medical terms for this type of endometriosis are Deep Infiltrating Endometriosis or Deep Fibrotic Endometriosis.

Endometriosis can be treated in a number of ways.  There are many medical options such as birth control pills and shots, intrauterine devices and injections such as GnRH agonists that put the body into a menopausal state.  These therapies only make the endometriosis dormant and does not "cure" it.  The stronger therapies such as GnRH agonist injections are limited in their duration of safe use.  Some newer evidence shows promising results using aromatase inhibitors to decrease the estrogen stimulation to the endometriosis.  It is important to realize that none of these therapies get rid of the disease.  They are useful, however in patients whose pain is controlled on the medicines and allows some patients to avoid surgery.

The only therapy ever shown to "cure" endometriosis is surgery.  That being said, it provides a "cure" in only 50-60% of patients.  Surgery combined with post operative medical therapy tends to give patients the longest pain free interval after treatment. 

It can be difficult for a physician to adequately know the extent of the disease prior to surgery. Symptoms and physical exam in the office are very important.  In Europe and South America, some institutions are using vaginal ultrasound to locate implants in and around the rectum. Skilled ultrasonographers can deterime the location, size and depth of endometriotic nodules. I am beginning to impliment this technique into my practice.  Hopefully, this will allow me to better predict the extent of the diseae prior to surgery.

Surgery for endometriosis can be very complex.  The endometriosis is often located around areas that are of concern the the gynecologic surgeon.  These include the bowel, bladder, vagina and ureters.  I feel it is important in planning your surgery for endometriosis to choose a surgeon who has experience in working around these areas and are trained in dealing with the complications or injuries that may occur.

One common practice is to perform a hysterectomy in patients with painful periods.  Sometimes a hysterectomy is performed without knowing if endometriosis is present.  If the uterus is removed without removing the surrounding endometriosis, patients may have continued pain or future complications.  I have come across a few patients who have had a hysterectomy performed, either vaginally or through an abdominal incision, who had endometriosis left behind.  In these cases, I have discovered endometriosis growing into the wall of the rectum, the bladder and the vagina, and completely encasing the ureters.

In many patients with painful periods and endometriosis, it is not necessary to have a hysterectomy performed.  If the endometriosis does not involve the uterus, it is often adequate to remove the endometriotic implants and nodules throughout the pelvis and abdomen, thus preserving fertility.  This is especially important in young patients.

Press Release About Lack of Information for Minimally Invasive Procedures

This is a link to a press release by the President of the American Association of Gynecologic Laparoscopy. It has some data to suggest that patients are not made aware of minimally invasive options to treat common gynecologic disorders. http://www.prnewswire.com/mnr/aagl/33994/

Minimally Invasive Hysterectomy (video link to right)

Laparoscopic Hysterectomy, or "Band-Aid Hysterectomy", is a wonderful option for many women who need a hysterectomy. Overall, laparoscopic hysterectomy is indicated as an alternative to open or abdominal hysterectomy. In this discussion I will talk about the indications, the benefits and risks and different methods of laparoscopic hysterectomy.

The indications for laparoscopic hysterectomy are similar to those for abdominal hysterectomy. Any patient who has previous abdominal surgery such as cesarean section or surgery for ovarian cysts may not be a candidate for a vaginal hysterectomy. This is due to the risk of adhesions of the bladder or other organs with in the abdomen. Also in patients with limited uterine descent, the uterine support is still very good. Patients with a concern for other intra-abdominal problems such as infection or endometriosis. Also women with a very large uterus that is too big to be removed vaginally.

It has been shown that vaginal hysterectomy is the safest method when possible. However; when there are contraindications to vaginal hysterectomy, laparoscopy offers some significant benefits over abdominal hysterectomy. The biggest benefit is the recovery time and hospital time. A patient who has had an abdominal hysterectomy usually stays in the hospital for 3-4 days because of the invasiveness of the procedure. A bikini type incision is made on the low abdomen and the abdominal muscles are separated. Pain is more significant because of the larger incision. Laparoscopy offers a similar hysterectomy through smaller “keyhole” incisions. In performing a total hysterectomy through the laparoscope I typically place 4 incisions, the largest being approximately 1.5 cm in the belly-button. Laparoscopy usually allows a patient to go home within 24 hours of surgery and is considered an “outpatient” surgery. Patients usually are able to perform normal activities sooner. The normal course for my patients after total laparoscopic hysterectomy has them feeling close to normal in 10-14 days.

Another benefit is the increased ability to see small disease. If there is endometriosis or other problems, the laparoscope magnifies the view inside the abdomen and allows me to see better. I can then remove any disease that I see. I can look all around the abdomen also, including visualization of the liver, gallbladder, stomach and spleen. Adhesions, or organs sticking to each other, are more common after abdominal or open procedures. Laparoscopy decreases the likelihood of forming adhesions due to smaller incisions and increased ability to control very small bleeding.

Some of the risks of laparoscopic hysterectomy include injury to major blood vessels during entry, injury to bowel, bladder or ureters. Early studies have shown laparoscopy to be more risky than vaginal surgery. But again, laparoscopy is not an alternative for vaginal hysterectomy. I feel that laparoscopic suturing is a very important skill for anyone performing laparoscopic hysterectomy. This allows management of most complications without having to convert to laparotomy.

Laparoscopic hysterectomy can be divided into three categories. The first is laparoscopic assisted vaginal hysterectomy. This is performed in women with good uterine descent who have other abdominal concerns that need to be addressed. Some of these concerns may be an ovarian cyst, endometriosis, or adhesions. Most gynecologists can perform some portion of the surgery through the laparoscope. The next one is laparoscopic supracervical hysterectomy or “LSH”. This is performed fully laparoscopically by removing only the upper portion or “fundus” of the uterus. The cervix is left in place. The only benefits to this are quicker recovery, limited post operative restrictions, quicker return to intercourse, and not interrupting the uterine support that is already in place. Many patients believe and are told that sexual response is better with leaving the cervix; however, many studies have shown no benefit in this regard. This type is also less risky because the uterus is “amputated” at a level above the ureters and bladder. The next type is total laparoscopic hysterectomy, or “TLH”. This procedure performs the hysterectomy in a similar fashion to abdominal hysterectomy. The full hysterectomy removes both the fundus of the uterus and the cervix. The top of the vagina is then closed and support is re-established to supporting ligaments. This is a very good alternative for a woman who needs a hysterectomy who also needs or wants to have her cervix removed. Concerning surgical management of gynecologic and uterine problems, a physician who can perform laparoscopic hysterectomy can offer a full line of options to each patient.
