Dr. Indman, before reading anything else, I want to know
what is your bias regarding hysterectomy?
I have been involved in learning about and helping to develop alternatives to
hysterectomy for many years. I have been instrumental in refining the use of the
laser in an office setting to treat pre-malignant diseases of the cervix. I have
treated thousands of women with the laser, many of whom would have otherwise had a
more invasive treatment or hysterectomy.
I introduced laser endometrial ablation as an alternative to hysterectomy to
Northern California in 1985, and have taught techniques of endometrial ablation,
hysteroscopy, and laparoscopy, both locally and nation wide. I have also been
involved in clinical research involving other alternatives to hysterectomy.
As a gynecologist in private practice, I see many patients referred by other
gynecologists for hysterectomy alternatives. I have nothing to gain financially if
these women decide to have a hysterectomy, as I send them back to the referring physician
for the procedure. So it is to my financial disadvantage if that woman has a
hysterectomy. (I also see patients who refer themselves; if a women is not
referred by another gynecologist and chooses to have a hysterectomy, I will do the
procedure if they would like me to.) Many times however, I am able to find less
invasive alternatives for women who are told that they need a hysterectomy.
So what's your point?
It's very simple. I want to help women make the best decision possible - one that
is based on knowledge and fact rather than on myth and misinformation.
How can I tell what is fact and what isn't?
That's not easy to do, and may take lots of research! For example, if I
pointed out that only 5% (I'm making up a number) of women undergoing hysterectomy could
play violin after the surgery, your first question would be how many could play the violin
before surgery. Seems simple, but if we compared a group of nurses having
hysterectomies with a group of music teachers not having surgery, it would be easy to
conclude that hysterectomy impairs violin playing. Does this example sound absurd?
If you were to review studies about hysterectomy, you would find that this very
type of mistake was frequently made. Although you will often see results of these
studies quoted, you would only realize that they are meaningless if you were go back to
the original studies, or read a review paper discussing it. (I will list several
excellent reviews in the "references" section.)
The best type of study is a randomized prospective study, in which subjects are matched
before treatment, and then randomly selected to undergo hysterectomy or some other
treatment. Obviously, this is a difficult type of study to do, but studies that
evaluate subjects before as well as after treatment are still better than retrospective
studies.
In addition, statements that sound logical may or may not be correct. Such
statements need to be tested before being accepted as true. I'll present some of
these too.
Well, are you for or against hysterectomy?
Hysterectomy is not a religion that one believes in. It is not a political
position that I am for or against. It is a surgical procedure that like any other
surgical procedure has both advantages and disadvantages. There are many situations
in which less extensive surgery may be preferable. There also are times when a
hysterectomy may be the best alternative. Each situation is unique.
Why not have a hysterectomy?
Although improvements in medical care have shortened the time required to recover from
a hysterectomy, it is still a major operation. There is a small risk of serious
complications and even death. These risks need to be compared to the risks of other
treatments or no treatment at all, and should be compared to other risks we take in
everyday living.
There is also pain associated with major surgery. I have found that newer
techniques of pain control have greatly reduced this, so most women who are otherwise in
good health are able to go home the next day after a vaginal hysterectomy, and two days
after an uncomplicated abdominal hysterectomy.
There are many ways to classify hysterectomy. Many terms are used in lay articles
differently than by the medical profession. For example, many people think that a
"total hysterectomy" means taking out the tubes and ovaries. Wrong!
It means taking out the entire uterus, with or without removing the ovaries. In the
old days, surgeons couldn't safely take out the entire uterus, so they would leave the
cervix. This is called a subtotal hysterectomy. Recently there has
been renewed interest in leaving the cervix. A special type of hysterectomy, called
a radical hysterectomy is done for certain types of cervical cancer.
In medical terms, anything to do with the ovary uses the term "oopher" and
the tube is referred to as the "salpinx" (or snake). Removing both tubes
and ovaries is called a bilateral (meaning both sides) salpingo-oophorectomy,
or "BSO". A BSO may or may not be done with any type of
hysterectomy.
The other major distinction, with multiple variations, describes how the uterus is
removed. If it is removed through the vagina, the procedure is called a vaginal
hysterectomy. If it is removed through an incision in the abdomen, it is called
an abdominal hysterectomy. Removing the uterus with the cervix through the
abdomen is called a total abdominal hysterectomy, or TAH. The
ovaries may or may not be removed at the same time.
What is a "laparoscopically assisted vaginal hysterectomy" (LAVH)?
There is little debate that recovery is faster if the uterus is removed through the
vagina without the need to make an abdominal incision. Some disease processes make
the vaginal approach difficult or impossible. Such situations may include large
ovarian cysts, extensive endometriosis, large fibroids, or unexplained pelvic pain where
the gynecologists needs to get a good look at the pelvic organs. In some situations,
the surgeon may be able to insert a laparoscope, (a small telescope) through the
belly button and be able to see the entire pelvis. Other instruments are inserted
through other tiny incisions in the abdomen. These instruments can be used to
perform parts of the hysterectomy, and to allow it to be completed through the vagina.
In a laparoscopic hysterectomy (or LH) the entire (or most of
the) procedure is done through the laparoscope.
Why not do all hysterectomies this way?
A LAVH or LH is often less invasive than an abdominal hysterectomy, but more invasive
than a vaginal hysterectomy. If the procedure can be done vaginally, then no
incisions are needed in the abdomen. There are no data showing that LAVH is superior
to vaginal hysterectomy (if it can be done safely). There are situations in
which I cannot tell which is the best approach until I actually can see the uterus and
ovaries. It this situation it is often helpful to look with a small laparoscope, and
make a decision based on what I see.
Are there still reasons to do an abdominal hysterectomy?
Given enough hours in the day, a skilled laparoscopic surgeon can probably do almost
any hysterectomy through the laparoscope. The problem comes in when the time and
effort required puts the patient at increased risks for complications. New
instruments are aiding in the removal of large tumors, such as fibroids, through the
laparoscope. Still, many times the safest route may require an incision.
In some operations, such as the removal of a gallbladder or ovarian cyst, most of the
trauma and recovery is from the incision rather than from what is done inside.
Recovery is much faster if these operations are done through the laparoscope.
With a hysterectomy, however, much of the healing required is in the tissues around
the uterus. So although recovery is faster when an incision is avoided, the
difference is not as great as it is with some other operations.
Claim: Hysterectomy causes depression.
There is no question that some women are depressed after hysterectomy. Many women
are also depressed before hysterectomy. The real question is "does hysterectomy
cause depression?" Obviously, asking a group of women who have had a
hysterectomy if they are depressed would give us no information about whether the
hysterectomy caused the depression. This is a difficult problem to evaluate, and
proper study design is crucial if we are to get valid information.
This topic is too large to tackle in depth in this summary, so I will quote several
articles (which I will list in references). You are welcome to disagree with the
statements, but please review all of the source material first. Also, I am not
a psychiatrist, and will not begin to claim to be an expert in depression.
A review of outcomes of hysterectomy by Karen Carlson, M.D. in Clinical Obstetrics
and Gynecology in 1997 summarized the studies on depression after hysterectomy:
- Early studies claiming that hysterectomy causes depression were of poor design, and
seriously flawed.
- "In the past decade, however, more methodologically sound studies have established
that hysterectomy for benign disorders does not cause depression and may decrease
psychiatric symptoms in many women."
This is a well done review, and I highly recommend reading the article. The same
physician also co-authored two excellent studies on outcomes of hysterectomy, which I
recommend reading as well.
My two cents... Personally, if I knew that I was going to have
horrible pain every month, or bleeding keeping me from doing what I want to do, I would be
pretty depressed about it. Treatment of the problem would be expected to help the
depression. What about depression from the surgery? Certainly some
depression after any surgery is not uncommon, especially if the recovery limits
activities. But I have found, as is supported by scientific studies, that depression
before surgery is the best predictor of depression afterwards. In addition, if
someone is convinced that they will be depressed after surgery, it usually is a
self-fulfilling prophecy.
How would a male gynecologist begin to know anything about a woman's orgasm?
Easy. In my pre-operative counseling for hysterectomy I discuss sexuality,
orgasm, and hysterectomy. And I tell my patient that a year later I'm going to ask
her about it. But this is not a controlled scientific study, so before telling you
what I am hearing, let's look at some real data. Again, don't take my word for
it. Go to the sources listed in the references. And if you like, check out their
references.
First, I was amazed when I reviewed some of the early publications. Retrospective
studies, with no control groups. Honestly, they proved about as much as did my
"violin" example above: absolutely nothing.
Dr. Carlson also reviewed a number of studies on sexual function after hysterectomy in
the above referenced article. Most interesting, perhaps, was a well done,
prospective study which she co-authored: The Maine Women's Health Study (see
references). In Part I a number of health related questions were evaluated before
and after hysterectomy. In Part II, a comparable group of women with similar
problems treated without hysterectomy were evaluated. The results are interesting.
After hysterectomy 7% of woman experienced "lack of interest in sex".
Of those treated without hysterectomy 6% of women had the same complaint.
This is not a significant difference. "Lack of enjoyment of sex" was
reported in 1% of women having hysterectomy and in no women without hysterectomy.
Another study, by L. Helstrum (see references), concluded
that the most predictive factor in postoperative sexuality was preoperative sexual
activity.
What women tell me after hysterectomy: The most
frequent response to the question of how sex and orgasm are a year after
hysterectomy is that there is no change in the way they feel
orgasm. Some women report that they are able to enjoy sex more since they
no longer have a problem
that interferes with sex. Others report no change. A small number
of women tell me they have less interest in sex. Other women tell me
that orgasm is better and more intense now that they've had a hysterectomy
(don't ask my why). I have also heard once that orgasm is "different" than before. Not
"bad," just different. And some women who had sexual dysfunctions before
hysterectomy had sexual dysfunctions after hysterectomy.
My impression regarding depression is that infertile women who desired children, and
had a hysterectomy because of a problem that caused infertility such as endometriosis, may
have a hard time coping with the finality of the realization that they would never carry a
child. And certainly women who have a problem with depression before surgery often
still have the problem afterwards. At times however, the resolution of a problem
that interfered with a woman's health and was a major focus in her life often improved
emotional well-being.
Before surgeons learned how to safely remove the cervix (which is really the lower
portion of the uterus), it was left in place during a hysterectomy. In the 1950's
improvements in surgical technique and the desire to prevent cervical cancer resulted in
the adoption of the routine removal of the cervix with the rest of the uterus at the time
of hysterectomy. Currently there is a resurgence of interest in leaving the cervix
at the time of hysterectomy. The short version: there are many arguments in
favor of leaving the cervix, but very little data to support or to disprove these
arguments. I do have the impression is that recovery from surgery is
faster when the cervix is left in. What are some of the arguments?
Statement: There is less risk of vaginal vault prolapse with subtotal
hysterectomy (the vagina falling out). It is argued that
the supports of the vagina are damaged by removal of the cervix.
Counterpoint: Uterine prolapse (the uterus falling out) is a common
indication for hysterectomy. The supporting structures are frequently damaged by
childbirth, and can be repaired during hysterectomy.
Fact: There are no good studies comparing vaginal prolapse with and
without removing the cervix. Lot's of arguing, but no data.
Statement: Orgasm is better with the cervix left in. In
1983 Kilkku published a study showing more frequent orgasms after supracervical
hysterectomy than after total hysterectomy. It is argued that the nerves in the
cervix are important for orgasm.
Counterpoint: Much of this argument comes from Kilkku's 1983 study
(see references). The flaws in this study were numerous. This was a
retrospective study in which there was not even a baseline assessment of the subjects.
It is impossible to draw any meaningful conclusions from this study.
Fact: In order to study this, it would be necessary to evaluate a
group of woman planning hysterectomy, randomly leave the cervix in half of them, and then
re-asses orgasm at a given time after surgery. Once again, strong opinions, little
information.
Statement: If the cervix is normal then leave it in.
Counterpoint: It is easier to leave in the cervix if the uterus is
removed through the abdomen, but the reverse is true for a vaginal hysterectomy.
Although we have good screening methods for cervical cancer, adenocarcinoma (cancer of the
glands inside of the cervix) is increasing in frequency, and can be fatal. In
addition, there are now reports of having to go back and remove the cervix after a
supracervical hysterectomy because of bleeding or other problems.
Fact: There is a small but definite risk of cancer in a remaining
cervix, and of needing to have surgery to remove the cervix at a later time if it causes
problems. The arguments about pelvic support and sexual functions have not been
tested, so their validity is unknown. Hopefully there will be good prospective
studies to better determine whether or not it is best to remove the cervix.
Sounds like you're for hysterectomy after all...
I'm not for or against hysterectomy. If less invasive alternatives have a
reasonable chance of solving a problem, then in most cases that would be preferable.
That is why I am so aggressive about promoting hysteroscopy, hysteroscopic
procedures, and laparoscopic procedures when they are medically appropriate.
On the other hand, I don't want any woman to be to be afraid of hysterectomy because of
myths and misinformation. Most women who have a hysterectomy do very well. On
the other hand, if a less invasive alternative is available, give it serious
consideration!
