Tubal Ligation Reversal - Untying Tied Tubes


Untying Tied Tubes: Bipolar Electrocoagulation


History of Tubal Sterilization

The first tubal sterilization procedure, reported in 1881, was tubal ligation and resection. Ligation and resection - or ‘tying tubes’ was the most common surgery for sterilization until the advent of laparoscopic surgery in the mid 1900’s. As laparoscopic surgery became more popular, electrocoagulation (electrical burning) of the fallopian tubes became an additional method of surgical sterilization. Tubal sterilization by electrocoagulation uses electric current to cut and destroy the portion of the tube that is exposed to the electric current. These portions of the tube eventually heal and close.

Monopolar Tubal Coagulation

Tubal sterilization with monopolar coagulation forceps.The initial method of laparoscopic tubal coagulation, in 1962, used a type of electrical current termed monopolar current. Monopolar tubal electrocoagulation was a popular type of laparoscopic sterilization through the 1970’s and 1980’s. The medical community began to realize that the complication rate from this form of electric surgery was higher than for other electric surgical methods of tubal sterilization. Sterilization procedures done by monopolar current have gradually been replaced with bipolar current.

Bipolar Electrocoagulation of the Fallopian Tubes

Tubal sterilization with bipolar coagulation forceps.The first reported sterilization using bipolar electrocoagulation was in 1972. This was done via a laparoscope inserted just under the belly button. During bipolar coagulation, the electrical current can be more precisely controlled, resulting in less tubal damage than monopolar coagulation. This sterilization procedure results in higher reversal success rates than monopolar electrocoagulation.

Reversing Tubal Sterilization

Many people, including doctors, mistakenly believe that tubal sterilization is permanent and irreversible. Although bipolar coagulation sterilization is intended to be permanent, this procedure can be reversed successfully in almost all cases. The success rates depend on how many different areas of the tube were damaged with electrocautery. Approximately 60- 70% of patients at Chapel Hill Tubal Reversal Center become pregnant after a reversal of a bipolar coagulation sterilization procedure. Chapel Hill Tubal Reversal Center is the only medical facility that specializes exclusively in reversal of tubal ligation. We perform tubal ligation reversals every day, and our tubal reversal doctors are experts in reversing all types of tubal ligations- or ‘untying’ tubes that have been ‘tied’!


Untying Tied Tubes: Falope Ring Sterilization


Falope Ring Sterilization

Falope ring tubal sterilization.The Yoon Falope rings were developed in the 1960’s as a safer alternative to laparoscopic monopolar cautery tubal sterilization. This procedure is performed by inserting a laparoscope just under the belly button. The fallopian tube is then identified and a device holds the tube while the silastic ring is slid over a 2-3 cm ’knuckle’ of tube that is kinked off by the ring. This is done once for each side.

The common misperception is that the Falope ring is what prevents pregnancy and that reversal of the procedure simply requires removal of the ring. The Falope ring causes the squeezed ’knuckle’ of tube to undergo avascular necrosis (to die and become absorbed by the body). After this happens the ends of the tubal segments outside the ring close up, thereby preventing sperm from reaching the egg.

Falope Ring Sterilization Reversal

Reversing Falope ring sterilization is not as easy as just removing the ring. The closed ends of the tubes must be opened and the tubal segments must be rejoined.

Falope rings cause destruction of a minimal length of fallopian tube and reversal of this type of tubal ligation gives excellent results. Approximately 75% of patients at Chapel Hill Tubal Reversal Center become pregnant after a reversal of a Falope ring sterilization procedure.

Many people believe tubal sterilization is permanent and irreversible. Although tubal sterilization with Falope rings is intended to be permanent, this procedure can be reversed. Chapel Hill Tubal Reversal Center is the only medical facility that specializes exclusively in reversal of tubal ligation.


Untying tied tubes: Hulka clips


Hulka Clip Sterilization

One common form of female sterilization is the use of Hulka clips to block the fallopian tubes. The Hulka clip was approved for use in the United States in the 1970’s and was invented in Chapel Hill, North Carolina by Dr. Jaroslav Hulka at the University of North Carolina at Chapel Hill.

Hulka clip in the laparoscopic applicator.The Hulka clip is a small, gold plated stainless steel spring loaded clip. The clip in introduced into the abdominal cavity via a laparoscopic clip applicator. This image shows the open clip in the applicator and the tip of the laparoscope with its fiber optic lighted end. When the clip is placed across the fallopian tube, it is closed and a small spring holds the clip firmly across the tube. The Hulka clip has the advantage of damaging only a very small portion of the fallopian tube- approximately 7mm (the thickness of three quarters stacked on each other).

Hulka clip closed across the fallopian tube.The Hulka clip causes bilateral tubal occlusion by squeezing a very small portion of the tube. The squeezed portion is deprived of its blood supply and eventually undergoes avascular necrosis (dies and is absorbed by the body). This causes the fallopian tube to be divided in half and the two ends to close up. The Hulka clip is held in place between the two divided tubal segments by a small amount of scar tissue which forms within the clip.

Hulka Clip Reversal

A common misconception is that the Hulka clips can simply be opened to reverse the sterilization process - that the tubes can be unclipped. Unfortunately, tubal ligation reversal for Hulka clips is not as simple as opening the clips. Hulka clip tubal occlusion is reversed by removing the section of the tube with the clip across it and then, using microsurgical techniques, joining the remaining tube segments back together in perfect alignment.

Tubal reversal of Hulka clip tubal occlusion is better than for most other methods of sterilization because such a minimal amount of tube is destroyed in the occlusion process. Approximately 76% of patients at Chapel Hill Tubal Reversal Center become pregnant after a reversal of a Hulka clip sterilization procedure.

Common Misconception About Tied Tubes

Tying tubes like tying a shoe lace.Many patients seem to imagine the fallopian tube is like a shoe lace which is tied up like a bow to prevent pregnancy. As tubal ligation reversal specialists, we wish it were that easy- then untying tied tubes would be easier!

‘Tying ones fallopian tubes’ is a common language phrase used to describe several different surgical procedures which result in sterilization (a procedure intended to permanently prevent pregnancy). The more correct medical term is bilateral (both sides) tubal occlusion (closure of the fallopian tube).

There are many different ways to occlude (close) the fallopian tubes: ligation and resection (tying and cutting), clips and rings, and coagulation (burning). No matter how the procedure is done the end result causes the tube to close, heal shut, and prevent sperm from fertilizing an egg.

Tubal Sterilization is Reversible

Many people believe tubal sterilization is permanent and irreversible. Although Hulka clip sterilization is intended to be permanent, this procedure is ideal for tubal reversal. The Chapel Hill Tubal Reversal Center is the one medical facility which specializes in tubal ligation reversal.

We have become experts in reversing all types of tubal ligations- or ‘untying’ tubes that have been ‘tied’!


Untying Tied Tubes: Filshie Clip Sterilization


Tying Tubes is Not Like Tying a Shoe Lace

Tubal Ligation Methods

There are many different ways to occlude (close) the fallopian tubes: ligation and resection (tying and cutting), clips and rings, and coagulation (burning). No matter how the procedure is done the end result causes the tube to close, heal shut, and prevent sperm from fertilizing an egg.

Filshie Clip Tubal Ligation

One common form of laparoscopic (camera) sterilization is the use of Filshie clips to occlude both fallopian tubes. The Filshie clip was approved for use in the United States in the mid 1990’s. The Filshie clip is a small titanium clip which is lined with a thin silicone cushion. The clip was an improvement over the Yoon Falope Ring and the Hulka Clip because it was as easy to apply with less risk of operative complications. The clip also has the advantage of destroying only a very small portion of the fallopian tube- approximately 4mm (approximately the thickness of two quarters stacked on each other). The adjacent tube is not affected. The majority of Filshie clips placed in the United States are done by laparoscopic surgery; however, there is a growing trend to use them for tubal occlusion at the time of cesarean delivery (c-section).

Filshie clip applied to the fallopian tube.The Filshie clip causes bilateral tubal occlusion by squeezing a very small portion of the tube. The squeezed portion is deprived of its blood supply and eventually undergoes avascular necrosis (dies and is absorbed by the body). This causes the fallopian tube to be divided in half and the two ends to close up. The Filshie clip is held in place (in between the two divided ends) by a small amount of scar tissue which forms over the clip.

A common misconception is that the Filshie clips can simply be removed to reverse the sterilization process- that the tubes can be unclipped. Unfortunately, tubal ligation reversal for Filshie clips is not as simple as just opening the clips. Filshie clip tubal occlusion is reversed by removing the clips and using microsurgical techniques to open the closed ends and join the tubal segments back together in perfect alignment.

The reversal of Filshie clip tubal occlusion is usually technically easier than some other methods of sterilization because such a minimal amount of tube is destroyed in the occlusion process.

Approximately 76% of patients at Chapel Hill Tubal Reversal Center become pregnant after a reversal of a Filshie clip sterilization procedure.

Tubal Sterilization Can Be Reversed

Many people believe tubal sterilization is permanent and irreversible. Although Filshie clip sterilization is intended to be permanent, this procedure can be reversed. Chapel Hill Tubal Reversal Center is the one medical facility that specializes in tubal ligation reversal.

We have become experts in reversing all types of tubal ligations- or ‘untying’ tubes that have been ‘tied’!


Untying Tied Tubes


Tying Tubes

A simple lace tie. Many people seem to imagine the fallopian tube is like a shoe lace that is tied in a bow to prevent pregnancy. As a tubal ligation reversal specialist, I wish it were that simple- then reversing tied tubes would be a whole lot easier!

Perhaps a well meaning doctor may have told a patient one day, “I am going to tie your tubes so you don’t get pregnant.” Maybe the doctor wrote a letter to a medical journal explaining the procedure and then the terminology stuck. More likely, a reporter may have simplified the terminology for the surgical procedure of tubal ligation to make a catchy title for an article. Others may then have started using the term “tying tubes” to quickly explain a complex procedure. These explanations often have a long life span and make their way into common language.

The more accurate terminology is bilateral tubal occlusion (closure of both fallopian tubes) which results in sterilization (not being able to conceive). There are many ways to perform bilateral tubal occlusion. The most common tubal sterilization procedure is performed at the time of cesearean delivery (c-section) or immediately after having a baby. It does involve tying the tubes with a suture - but then also cutting out a segment of healthy tube, resulting in closure of the tube as it heals. The suture then dissolves. The intial suture tying is most likely where the phrase ‘tying tubes’ came from.

Another common method is to burn the tubes with electrical energy (electrocoagulation). This is usually done by laparoscopic surgery and is usually done remote from pregnancy. Lastly, there are many devices- clips and bands - which can close off the tubes and cause a portion of the tube to be destroyed.

No matter how the procedure is done, the end result is obstruction of the fallopian tube that prevents pregnancy.

Many people believe that tubal sterilization is irreversible. Although bilateral tubal occlusion is intended to be permanent, the procedure can be reversed. Chapel Hill Tubal Reversal Center is the one medical facility that specializes exclusively in reversal of tubal ligation. We have become tubal ligation reversal experts………experts at untying tied tubes!


Tubal Reversal Information


Tubal reversal information is plentiful on the internet, but not everything that you read is accurate or factual. Of the websites that provide information about tubal ligation reversal, the one from Chapel Hill Tubal Reversal Center is most complete and accurate. It describes the various types of tubal ligation procedures and the different tubal reversal procedures that can be used. If you are interested in learning about tubal reversal, spend some time looking at the different pages on this extensive site. There is a search box at the top of every page that can direct you to specific information about any issues relating to tubal ligation reversal. Take a look also through the many topics of information on the Tubal Reversal Blog.

Tubal Reversal Surgery

Tubal ligation reversal is usually considered to be a major operation, taking several hours and requiring a hospital stay of 1 to 5 days. Complete recovery is often described as taking 4 to 6 weeks. However, the tubal reversal procedure that Dr. Berger has developed is performed as outpatient surgery with no hospital stay required and with complete recovery generally within 5 to 10 days. Since hospitalization is not required, the cost of the tubal reversal procedure is reduced by half or two-thirds of the cost when performed in a hospital. Patients are more comfortable during their post operative recovery and are able to return to work and other normal activities much faster. A free video or DVD of Dr. Berger’s tubal reversal procedure is available on the Chapel Hill Tubal Reversal Center website.

Risks of Tubal Reversal

As with any surgery, complications are always a possibility. Although rare, these may include bleeding, infection, damage to other organs, or complications of anesthesia. The most significant risk associated with tubal ligation reversal is the long term risk of having an ectopic pregnancy. This risk is increased from approximately 2% of pregnancies in the general population to approximately 10% after tubal reversal. Fortunately, the medical problem of a ruptured tubal pregnancy can be prevented by following an early pregnancy monitoring protocol that has been described by Dr. Berger and is recommended to all women after a tubal reversal procedure.

Alternative Treatment

Rather than “untying” their tubes, some women are advised to be treated by in vitro fertilization (IVF). However, IVF is more complicated and expensive, the pregnancy rate after IVF is not as high as after tubal reversal, and there is a very high incidence of multiple births (approximately 30%) after IVF. Further, there is concern about the possible long term effect of the use of potent hormones to stimulate the ovaries to produce many eggs (called “super-ovulation”) and the suspicion that it might increase the risk of ovarian cancer later in life.

Am I a Candidate for Tubal Reversal?

Although most women have been told that tubal ligation is permanent, in fact, the vast majority of tubal ligation procedures are reversible. The operative report from your tubal ligation will give a good indication if the procedure can be reversed. When there is any doubt about this, diagnostic laparoscopy can be performed to examine the fallopian tubes and then decide whether to proceed with the reversal operation.

Pregnancy Rates After Tubal Reversal

Pregnancy and birth rates after a tubal reversal are significantly better than after IVF. Neither procedure, however, can guarantee that pregnancy leading to birth will occur. Even when the fallopian tubes have been repaired, other factors – such as age, menstrual cycle regularity, ovulation or other hormonal disorders, and the fertility of the male partner - may determine when, or whether, conception will occur.

Women under the age of 30 who have a tubal reversal have an 82% pregnancy success rate; between 30-34 the pregnancy rate is 76% and for women ages 35-39, the pregnancy rate is 67%. The pregnancy rate declines for women 40 and older in accordance with the natural decline in fertility with age. However, pregnancy rates are higher for women of any age following tubal reversal than after IVF.

Tubal Ligation and Tubal Reversal News: 2007


News stories about tubal ligation and tubal reversal in 2007.Past topics in the Tubal Reversal Blog include posts and comments about patient care at Chapel Hill Tubal Reversal Center. This topic summarizes important articles about tubal ligation and tubal reversal reported in the news during 2007.

Sterilization is Most Popular Family Planning Method
Approximately 10 million American women use the pill for contraception, while sterilization has been chosen by 15 million men and women.

One In Five Women Regret Decision For Tubal Ligation
One in five women under age 30 who undergo tubal sterilization later regret the procedure, despite the number of children they have.

Is Sterilization the Best Contraception Choice?
Women requesting a tubal ligation should be counseled regarding other long-term, reversible methods of contraception and informed that vasectomy is safer and more effective than tubal ligation.

Tubal Ligation Counseling Issues
Counseling about tubal ligation should include permanence of the method, possibility of future regret, and information about the specific techniques of tubal sterilization.

Relationship Conflict Before Sterilization
Women whose relationship was marked by substantial conflict before they underwent tubal ligation were most likely to regret the decision.

Young Age, Prodding Partner and Sterilization Regret
Young age and a prodding partner are risk factors indicating that a woman undergoing sterilization may later regret her decision.

Tubal Reversal Among Overweight Women
Overweight women’s chances of becoming pregnant after tubal reversal improve when they lose weight.

Dr. Berger’s Comment

These news reports touch on some of the issues patients talk about when they come to Chapel Hill Tubal Reversal Center for tubal sterilization reversal. The popularity of tubal ligation, and the fact that many women regret their decision to have a tubal ligation, are well documented. Young age and marital conflict are risk indicators for subsequent regret. Before performing a tubal ligation, doctors should ensure that the implications of ending childbearing potential are clearly understood and discuss vasectomy as an alternative permanent method of birth control. Women undergoing tubal reversal who are overweight should be aware that losing weight will improve their chances of becoming pregnant again.


Consenting to Tubal Ligation During Childbirth


I received an email message today from a patient that prompted me to write about informed consent for tubal ligation. (See my previous blog about informed consent for tubal reversal.) Here is the message that was sent to me.

Hello, Dr. Berger,

You performed tubal reversal surgery on me on 10/29/07, and I just found out that I’m pregnant. Thank you so much! This is such a blessing. I filled out the report and have heard back from Sarah Meacham. I’ll make sure to follow her instructions.

I’m writing because I have a friend named Samantha who wants to get reversal surgery, but she would like to make sure she’s a candidate based on the information in her operative report. I told her that I would send it to you so you can look it over, so it’s attached. She and her husband have two cute little girls, but she agreed to the tubal ligation on the operating table after she gave birth to her youngest at the prodding of her doctor. She said that she made a terrible mistake and wants more children. And like me, no one she’s asked in south Florida will even consider the procedure that you do. When I told her about you, she was ecstatic. And now that I’m pregnant, she knows that it works!

Thank you again for the miracles you work for so many women. God bless you and your staff!

Sincerely,
Amy P.

I was glad to hear that Amy was pregnant and had recommended to Samantha that she come here for her tubal reversal procedure, but this part of the message caught my attention:

“…she agreed to the tubal ligation on the operating table after she gave birth to her youngest at the prodding of her doctor. She said that she made a terrible mistake…”

What Is Informed Consent?

Before performing a tubal ligation - an elective operation - a doctor should always obtain the patient’s informed consent. Informed consent is the process through which the patient becomes educated about the procedure - including its benefits, risks and alternatives - and makes the decision to have the procedure performed. Informed consent implies that the patient fully understands the issues, has asked any questions she has, had her questions answered, and makes her decision under no duress. Adequate time should be allowed for a patient to think about all of the issues before consenting to the operation.

Should Consent For Tubal Ligation be Made During Childbirth?

Many tubal reversal patients have told me that the first time they discussed a tubal ligation with their doctor while they were on their way to the operating room for a C-section. Some regretted their decision while they were on the operating table or when they awoke in the recovery room. Other patients have said they had a tubal ligation in response to pressure from their spouse, parents, or their doctor. Labor and delivery is not the best time to think about an issue with such profound and lasting results as surgical sterilization. This should be discussed and thought about at leisure, not during the stress of childbirth.

Dr. Berger’s Comment

Besides the doctor’s responsibilities in obtaining informed consent, the patient also has a responsibility when giving it. A tubal ligation is not an emergency operation. Having a tubal ligation is a decision that should be carefully considered and not made in haste. There is adequate time during the pregnancy for a doctor and patient to discuss the issue of sterilization. Bringing this up for the first time on the way to the delivery room is a mistake, in my opinion. A more deliberate approach to the process of informed consent by both doctor and patient would help avoid mistaken decisions, such as in Samantha’s case.


Is Tubal Ligation Regret A Big Problem?


At Chapel Hill Tubal Reversal Center, we receive requests 7 days a week, 365 days a year, for information about tubal ligation reversal. These requests come from women who regret having a tubal ligation. A staff member recently asked me how big a problem this is throughout the country. The following is in response to this question.


How Many Women Have Had A Tubal Ligation?

There is no single data source reporting the number of surgical sterilizations performed in the United States. Based on multiple sources of information, it is likely that 650,000 to 700,000 tubal sterilizations are performed each year, and more than 11 million American women have had a sterilization operation. The latest study, conducted in 2002 by the US Department of Health and Human Services, indicates that between one in four to one in five of adult, sexually active women have had a tubal ligation.(1)

How Common Is Tubal Ligation Regret?

Many factors can affect a woman’s likelihood to regret sterilization. Among women who had a tubal ligation, risk factors for regret include young age, less education, and a husband or partner who wanted the woman to have a tubal ligation.

In 1999, a study called the Collaborative Review of Sterilization (CREST) found that 20% of women who were sterilized before the age of 30 regretted their decision. Women who were sterilized at a young age had a higher chance of requesting information about reversal, regardless of their number of living children. Also, women who reported conflict with their husbands or partners before tubal sterilization were more than three times as likely to regret their decision and more than five times as likely to request a reversal than women who did not report such conflict. (2)

Dr. Berger’s Comment

This statistical information helps give a broader picture to the significance of the issues and comments raised in the previous blog topic - Ethics of Tubal Ligation. Additional comments on this issue are welcome from all readers.

Tubal Reversal After Fimbriectomy Tubal Ligation


Tubal Ligation by Fimbriectomy

Fimbriectomy is removal of the fimbrial end of the fallopian tube.Fimbriectomy is an infrequent type of tubal ligation in the United States. This female sterilization method is performed by removing the fimbrial end of the fallopian tube. At the fimbrial end of the tube, the inner tubal lining faces outward towards the ovary. The tubal lining is rich in cilia that beat in coordinated waves to pull the egg into the tubal opening.

Many doctors think that tubal reversal cannot be successful following a fimbriectomy because of the loss of the egg-capturing fimbria. This is a mistaken notion. Cilia are abundant in the ampullary segment of the fallopian tube. The inner lining of the remaining ampullary tubal segment can be folded outward after opening the tube and can function as a new fimbrial end. The tubal reversal procedure for fimbriectomy reversal is called ampullary salpingostomy.

Fimbriectomy Reversal Pregnancy Rates

Chapel Hill Tubal Reversal Center publishes statistics updated annually regarding pregnancy rates and pregnancy outcomes for all of the women who have had tubal reversal procedures performed by Dr. Berger. The data for women who had tubal ligation procedures by fimbriectomy are from our Tubal Reversal Pregnancy Study Report 2007.

The overall pregnancy rate after fimbriectomy tubal reversal is 56% for patients at Chapel Hill Tubal Reversal Center. The following table shows the numbers and pregnancy rates according to womens’ ages at the time of their tubal reversal procedure.

Recommendations for Fimbriectomy Reversal

The success of fimbriectomy reversal depends upon having an adequate length of ampullary segment of the fallopian tube. The length of the remaining ampullary tubal segment can be determined from a hysterosalpingogram (HSG) or from diagnostic laparoscopy.

I recommend having an HSG or choosing the screening laparoscopy option when tubal ligation has been performed by fimbriectomy. An HSG can be ordered by the patient’s local doctor and the x-ray films sent to me for examination prior to scheduling tubal reversal surgery. Alternatively, patients can omit having an HSG and schedule their reversal surgery to start with screening laparoscopy. This will show if ampullary salpingostomy will be effective. If so, the tubal reversal procedure will be performed at the same time while the patient is under anesthesia.
