Definition - What does Tubal Anastomosis mean?
Tubal anastomosis is a surgical procedure that involves joining the fallopian tube segments that were previously separated as part of a procedure called tubal ligation. This procedure is typically done to facilitate natural conception and pregnancy.
Tubal ligation is a birth control procedure whereas tubal anastomosis is done to restore the fertility potential. Tubal ligation reversal can improve the fertility outcome by 42% to 60%.
Tubal anastomosis is also known as tubal ligation reversal surgery.
FertilitySmarts explains Tubal Anastomosis
A tubal anastomosis involves opening the blocked ends of the remaining tubal segments. Several surgical repair techniques are then used to restore the anatomy and patency (openness) of the fallopian tube. The tubal openings are brought close to each other by stitching the tissue underneath the fallopian tubes, which prevents the tubal segments from getting detached as the tube heals. To align the tubes and reconnect them, the tubal segments may be threaded with a narrow, flexible tube. This tube is removed after the surgery is completed. Finally, a dye is inserted through the cervix into the uterus, which will flow out through the tubes, confirming their patency.
The success rate of the reversal procedure depends on the length of the tube remaining and, the age of the woman, time interval between tubal ligation and reversal, site of ligation, and the site where the tubes are reattached.
Tubal blockage can still occur in around 6% of cases following tubal anastomosis. This likely mandates a second surgery to remove the blockage, a procedure termed as tubal reanastomosis or re-rejoining of the fallopian tubes.
