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

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

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’!

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.

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).

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

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’!

Patients often ask when they should have a hysterosalpingogram (HSG) to see if their fallopian tubes are open after tubal reversal surgery.

When to Have an HSG

Wait for at least 6 to 12 months after a tubal reversal procedure for this test of tubal patency. An HSG carries a risk of infection and often does not give conclusive results. It is best to give yourself a chance to become pregnant rather than rushing to have an HSG. Most patients conceive within this time frame and will avoid the need for an unnecessary and possibly misleading or harmful procedure.

Preparing for an HSG

To avoid unnecessary risks, an HSG should be performed only after menstruation is over and before ovulation occurs. Having an HSG after the time of ovulation may interfere with a pregnancy - before a pregnancy test can detect that conception has occurred. To minimize the risk of infection, use a betadine vaginal douche the evening before and the morning of the scheduled procedure and ask your doctor for a prophylactic antibiotic prescription. 600 mg of ibuprofen taken one hour before the HSG will minimize its discomfort.

What to Look For in an HSG

You can ask to watch the results on the fluoroscopy screen while the dye is being injected into the uterus.

At first, the dye will fill the uterine cavity. It is essential that the dye actually enter the fallopian tubes up to the point where the anastomosis was performed. Often, this does not occur due to spasm of the sphincter between the uterus and tubes (shown by the arrows) or from mucus or calcium deposits in the proximal tubal segments.

If the dye passes through the anastomosis sites, the fallopian tubes are open. Most radiologists do not consider the x-ray to show tubal patency (openness) unless dye spills into the abdominal cavity. When this happens, the diagnosis of tubal patency is conclusive.

We often see x-rays where dye has passed through the tubal  anastomosis site, but has not yet spilled into the abdominal cavity. This is due to an insufficient amount of dye being injected into the tubes. The radiologist may mistakenly believe the tube is blocked when in reality it is open.

Send Your X-Rays To Me

In order to be certain about whether an HSG demonstrates tubal patency, tubal occlusion, or is inconclusive, please instruct the radiologist to send the x-ray films to me to interpret. Having documented the anatomy and measurements of the fallopian tube segments during tubal reversal surgery, I can compare the x-ray findings with each patient’s operative report. This allows me to give the most accurate interpretation of HSG results.

Dr. Berger’s Comment

Hysterosalpingography is a widely available procedure to examine tubal anatomy. Unfortunately, it is often performed or interpreted inaccurately. An HSG also has risks as well as discomfort and cost. It is best to wait for at least 6-12 months after a tubal reversal procedure to have an HSG. Most patients will become pregnant after tubal reversal within a year and can avoid the problems associated with HSGs. Preparing properly for an HSG and sending the x-ray images to me will minimize the risks and errors associated with a hysterosalpingram.

Tubal Sterilization For Young Women With No Children

One of today’s patients at Chapel Hill Surgical Center was a woman in her thirties who recently become married and had a tubal ligation at age 24 years when she had no children. Her tubal ligation had been performed by a tubal coagulation procedure in which the fallopian tubes were burned at the junction of her uterus. The tubal lumen or opening within the uterine wall was scarred completely on both the right and left sides from the burning procedure. Therefore, the only way to perform a tubal reversal was through the technique of tubouterine implantation.

I mention this case because it was unnecessarily destructive, especially when performed for a young woman with no children. Many studies show that these are women who are most likely to change their minds later on and want to be able to have children. In this case, almost any other tubal ligation procedure would have been preferable. In my view, the best choice of a tubal ligation for a young woman with no children is the clip method (either Hulka clip or Filshie clip).

I have encountered other cases like this in the past. I wonder if the doctor who performed her tubal ligation considered the possibility that the patient might change her mind, and therefore it would be preferable to perform a tubal ligation better suited to reversing at a later time, should the need arise.

Comments Welcome

I am interested in what other people think about this.

If you have had your tubes tied and would like to become pregnant again, tubal reversal surgery is probably the best option for you. Tubal ligation reversal is the most successful and cost-effective way to become pregnant for 98% of women who have had a tubal ligation and now want to have another baby.

What Is Your Age?

The natural fertility rate declines with age. Pregnancy rates after tubal reversal, therefore, are highest for younger women.  Although pregnancy rates are lower for older women, you can still become pregnant after age 40 if you are ovulating and have periods.

Dr. Berger has kept detailed records of his patients and has compiled a comprehensive follow-up study on pregnancy after tubal reversal for all of his patients. His patients under 30 have a 77% pregnancy rate after having a tubal reversal procedure. The pregnancy rate is 72% for women ages 30-34 , 62% for women 35-39, and 34% for those 40 years of age and older after tubal reversal surgery performed by Dr. Berger.

What Type of Tubal Ligation Did You Have?

There are several ways that a doctor can tie a woman’s fallopian tubes. Women with the ring or clip method of tubal ligation have a 74% pregnancy rate after undergoing tubal reversal surgery. Women with the tubal coagulation technique have a 65% pregnancy rate, while women with tubal ligation and resection methods have a 62% probability for pregnancy after reversal surgery.

If you aren’t sure what type of tubal ligation you had, don’t worry! You can get a copy of your operative and pathology reports relating to your tubal ligation, and fax them to Chapel Hill Tubal Reversal Center at (919) 967-8637. Please attach the Fax Cover Sheet so we can reach you when your records arrive. Dr. Berger will review the operative report at no charge and we will contact you regarding possible outcomes for you following reversal surgery.

How To Choose The Best Tubal Reversal Doctor?

The most important question to ask is how many tubal reversal surgeries the doctor has performed. The more experience the doctor has, the better your outcome will be. Dr. Berger has the most experience with this operative procedure of any reproductive surgeon in the world and has performed more than 6,000 tubal reversals! He is considered by other medical professionals in the US and abroad to be the best tubal reversal doctor.

Also ask if the doctor performs tubal reversals on an outpatient basis. Outpatient tubal reversal reduces cost and avoids the risks of hospitalization, such as infection with hospital-acquired bacteria. Chapel Hill Tubal Reversal Center is the only center worldwide that is dedicated exclusively to outpatient tubal ligation reversal, and Dr. Berger is the only doctor who specializes in and limits his practice to outpatient tubal reversal surgery.

I Will Be Happy To Assist You

Tubal Reversal Procedures

There are 3 types of tubal reversal procedures:

• anastomosis
• implantation - (this blog topic)
• salpingostomy

Implantation of Fallopian Tubes

Implantation of the fallopian tube is inserting the tube through a new opening into the uterus. Tubouterine implantation is correct medical terminology, but it is also called tubal implantation, uterotubal implantation, or uterine implantation.

Most tubal ligation operations leave two fallopian tube segments that can be reconnected. In some cases, only one tubal segment remains that is separated from the uterus and the portion of the tube within the uterine muscle is blocked as well. This is most likely to occur when a tubal ligation has been performed by monopolar tubal coagulation applied to the tubal segment next to the uterus. In this situation, tubal implantation is required as the tubal reversal procedure.

How I Perform Tubal Implantation

Tubal implantation is performed by making an incision through the uterine muscle. The incision is carried down into the uterine cavity. The tubal segment that has been separated from the uterus is opened and passed down until its proximal end is inside the uterine cavity. Before implanting the tube in the uterus, a suture is placed through the open end that goes inside the uterus. This suture is used to anchor the fallopian tube within the uterine cavity.

When the tube has been anchored inside the uterine cavity, sutures are placed in the uterine muscle around the implanted tube. Care must be taken to close the uterine incision sufficiently to allow healing, but not so tightly that it compresses or constricts the implanted tube. Tubal implantation is a more difficult operation to perform than tubal anastomosis. Tubal implantation accounts for 1% of tubal reversal procedures at Chapel Hill Tubal Reversal Center.

Tubal Reversal Procedures

There are 3 types of tubal reversal procedures:

• anastomosis - (today’s blog topic)
• implantation
• salpingostomy

Anastomosis of Fallopian Tubes

Anastomosis connects two body parts. Tubotubal anastomosis is connecting two segments of the fallopian tube. Tubotubal anastomosis is correct medical terminology, but it is also called tubal anastomosis for short. Bilateral tubal anastomosis means that both tubes are repaired by the anastomosis technique. The anastomosis sites can be specified for each fallopian tube. They may be different for the two sides. For example, a patient may have a right isthmic-ampullary tubotubal anastomosis and a left ampullary-ampullary tubal anastomosis. Sometimes, only one fallopian tube is repairable with the anastomosis technique. This is called unilateral tubotubal anastomosis.

Bilateral Tubal Anastomosis

Most tubal ligation operations separate the fallopian tube into two segments. Bilateral tubotubal anastomosis, therefore, is the most common tubal reversal procedure. Bilateral tubal anastomosis accounts for 90% of the tubal reversal procedures at Chapel Hill Tubal Reversal Center.

How I Perform Tubal Anastomosis

After opening the blocked ends of the two tubal segments, I pass a flexible stent or thread through the tubal lumen or opening of the two segments until it reaches the uterine cavity. This ensures that the fallopian tube is open from the uterine cavity to its fimbrial end and that the tubal segments align properly. A suture placed in the connective tissue, just beneath the fallopian tube segments, draws the tubal segments together.

The muscular and outer layers of the tubal segments are connected with microsurgical sutures. Care is taken to avoid suturing the inner layer of the fallopian tube. Suture material is a foreign body. Stitches placed in the inner tubal lining can cause scarring inside the tubal lumen. When the two tubal segments are joined together, the stent is withdrawn from the fimbrial end of the tube.

Watch The Operation

The images above illustrate the principles of tubotubal anastomosis. For more details, you can watch the operation as it is being performed. A short video clip online gives an overview. If you want to watch the entire tubal anastomosis procedure, you can order a videotape or dvd of Tubal Ligation Reversal by Dr. Berger as shown on TV by the Discovery and Learning Channels. Watching the full length video will help you better understand how I perform tubotubal anastomosis as outpatient tubal reversal surgery.

What is Essure?

Essure is a permanent birth control device that has recently become available as an alternative to traditional tubal ligation methods. The spring-like device is inserted through the uterine cavity into the tubal openings using a hysteroscope. This can be done as an in-office procedure. The device expands to fill the tubal opening and then becomes scarred into place, forming a barrier so that sperm cannot reach the egg. Because of the scar formation, it cannot be pulled out of the tube. It is advertised by the manufacturer as a permanent method of birth control. In this respect, it is similar to other tubal ligation methods that are considered by most doctors to be permanent.

Here is a link to an online video animation of the placement of the Essure device into the fallopian tubes.

Is Tubal Reversal Possible For The Essure Device?

I perform 4 tubal reversal procedures each day at Chapel Hill Tubal Reversal Center. The women who come here have all varieties of tubal ligation methods. Today, one of the patients had the Essure sterilization method. When she chose this form of tubal sterilization, she was unaware that she would become remarried and want to be able to try to have a child with her new husband.

Although I could not find any previous references regarding attempts to reverse the Essure procedure, I agreed to attempt to perform a reversal for her. The way I did this was to cut the device out of the uterine muscle and then implant the remaining fallopian tube into the uterine cavity through a new opening in the uterus. This procedure is called tubouterine implantation.

The reason I removed the device was that part of the metal spring projects into the uterine cavity. If a pregnancy were to occur with the device in place, this could be harmful to the pregnancy. To my knowledge, this is the first time that the Essure sterilization procedure has been reversed.

Pomeroy Technique of Tubal Ligation and Resection

The most common type of tubal ligation is the Pomeroy procedure, named after Dr. Ralph Pomeroy who described it in 1930. The Pomeroy method involves picking up a segment of the fallopian tube to create a knuckle, placing a tie or ligature with absorbable suture around its base, and then cutting off the knuckle of tube above the tie. As the suture dissolves, the 2 remaining tubal segments separate from each other.

“Modified” Pomeroy Techniques

Interestingly, Dr. Pomeroy did not publish his technique in the medical literature but simply demonstrated it to other doctors. Some of them subsequently published the technique, but with modifications.

Currently, many doctors use the term modified Pomeroy procedure when they describe the tubal ligation they have performed in a patient’s operative report. Each doctor seems to have his or her own way of operating and there are many variations from the original method. Some doctors use absorbable suture, while others use permanent sutures that do not dissolve. Some doctors place more than one tie around the tube and many doctors also burn or cauterize the tubal ends.

A tubal ligation operative report is useful as a guide but does not predict exactly what the remaining tubal segments will be at the time of a reversal procedure. Fortunately, Pomeroy tubal ligation and its modifications are usually excellent in terms of reversibility.

Pomeroy Tubal Ligation Reversal Success

At Chapel Hill Tubal Reversal Center, we keep a record of all patients’ tubal reversal operations, including the tubal ligation method, the remaining tubal segment lengths, and other important findings at the time of surgery. Since we maintain long term follow-up with our patients, we are able to provide accurate statistics about pregnancies and their outcomes after tubal reversal surgery. Here are some of the pregnancy statistics for women who have had a Pomeroy type of tubal ligation.

Pregnancy Rates of Our Tubal Reversal Patients

The overall pregnancy rate after Pomeroy tubal ligation reversal is 70% for patients at Chapel Hill Tubal Reversal Center. The table below shows pregnancy rates according to women’s ages at the time of tubal reversal. The first column shows ages by 5 year groupings. The second column shows the number of women in each age group who had a tubal reversal. The third and fourth columns show the number and the percentage of women who became pregnant after their reversal procedure. The data shown in this table come from our Tubal Reversal Pregnancy Study Report 2007.

Here is how the pregnancy rate is calculated: The number of pregnant women (column 3) divided by all women in that age category who had reversal surgery (column 2) times 100 equals the percentage of women who became pregnant (column 4). A doctor has to know all of this information in order to be able to state what the success rate is for his patients.

Pregnancy Rate By Age After Pomeroy Tubal Reversal

Good News About Pomeroy Reversal

The good news is that for women under age 40, two-thirds to four-fifths will become pregnant following a tubal reversal procedure. Even for women age 40 and over, approximately 4 out of 10 will conceive another pregnancy. From the follow-up data that we have for our tubal reversal patients, there is good reason for optimism when reversing a Pomeroy tubal ligation.

Almost every article one reads about tubal ligation stresses that it is permanent. Most doctors and the lay public believe this to be true. In my experience, however, tubal ligation is reversible in over 95% cases!

Doctors stress that tubal ligation is a permanent method birth control because it cannot be discontinued easily such as stopping the use of birth control pills or the patch, removing an IUD, or avoiding the use of barriers contraceptives (condom or diaphragm). In the past, reversing a tubal ligation procedure involved complicated surgery with its attendant high cost (up to $35,000). The outpatient tubal ligation procedure that I have developed is uncomplicated surgery and avoids the expense of hospital charges. This has reduced the cost of tubal reversal surgery to under $6000. This is less than the cost of a single treatment cycle with in vitro fertilization (averaging $10,000 - $12,000). My effort over the past 3 decades has been to make tubal reversal surgery easy to undergo and affordable for couples.

There are some methods of female sterilization that are not reversible. These include complete removal of the fallopian tubes (total salpingectomy) and extremely destructive methods of partial salpingectomy that do not leave two segments to repair. An example of the latter is when only a short portion of the tube is attached to the uterus and the remaining segment contains only fimbrial tissue with no tubal muscle or opening. In this case, the fimbrial tissue alone cannot be rejoined successfully to the uterine segment of tube. Fortunately, this is an unusual occurrence. In cases where there is a sufficient length of tube attached to the uterus, it can be opened and be able function normally even without the fimbrial end. This is called ampullary salpingostomy. This technique is useful in reversing a fimbriectomy (removal of the fimbrial or ovarian end of the fallopian tube).

Reviewing the operative report from a tubal ligation procedure usually will indicate how destructive the procedure was. When there is a question about this, diagnostic laparoscopy can be performed to examine what remains of the fallopian tubes. If there are sufficient segments to repair, tubal reversal can be done right then while the patient is under anesthesia.

The best method of tubal ligation to reverse is the clip procedure. The Hulka Clip was developed in the 1970s by Dr. Jaroslav Hulka, a professor of obstetrics and gynecology at the University of North Carolina at Chapel Hill. (Dr. Hulka was one of my most influential teachers during my residency in ob-gyn at UNC.) The tubal ring also is an excellent method for reversing. The clip and ring procedures tend to damage the least amount of the fallopian tube and leave behind long segments to repair.

The most common tubal ligation procedures involves tying and cutting the tubes (ligation/resection) or burning the tubes (coagulation). Experience shows that 98% of these procedures are reversible.

Summary: Tubal ligation is not really permanent in the sense that it can be reversed in almost all cases. This is fortunate for those women who want another chance to have a baby after having their tubes tied. Tubal reversal is more successful, less complicated, and less expensive than the alternative treatment of in vitro fertilization.
