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 When the two tubal segments are joined together, the stent is withdrawn from the fimbrial end of the tube.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.

Answers To Common Questions About Essure Reversal

We have provided answers to common questions about Essure reversal in the following blog article,  Essure Reversal: What You Need To Know .

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.
