Tubal Ligation Reversal

Tubal ligation reversal (also known as "untying the tubes") is the rejoining of the fallopian tubes in women who have undergone voluntary sterilization. It is one of the most effective tubal reconstructive surgeries available, especially if the tubal ligation was performed with clips or rings.

Microsurgical tubal reanastamosis is the standard procedure for tubal ligation reversals. Using a laparotomy (incision in the abdomen), a horizontal incision is made above the pubic bone. Through this incision, the tubes are exposed and are reattached using microsurgical suture techniques. Dye is injected to confirm that the fallopian tube passageway is open. This procedure can be done safely and successfully on an outpatient basis, but most patients spend one night in hospital.


This outpatient procedure offers the following benefits:

Low cost.
High probability of uncomplicated postoperative period.
Rapid recovery and return to full activity.

Approximately 55% to 70% of women will become pregnant following this procedure. The success rate is affected by the woman's age when she tries to conceive. The surgery is less successful if the tubes were cut (burned) using an elecrocautery instrument or if other pelvic disease such as scarring or endometriosis is present.

The main risks associated with tubal ligation reversal are a blockage rate of approximately 5% and an ectopic pregnancy rate of 8% to 12%. When a positive pregnancy test is detected following tubal ligation reversal, an early ultrasound and blood work should be done to identify a possible ectopic pregnancy.
