Tubal sterilization is an increasingly common method of contraception. Available evidence suggests that sterilization fails in 0.13-1.3% of sterilization procedures and of these, 15-33% will be ectopic pregnancies. The risk of ectopic pregnancy is 12.5% for women who have had tubal ligation, which is a greater risk than for those who have not had the surgery. An ectopic or extra uterine pregnancy is one in which the blastocyst implants anywhere other than the endometrial lining of the uterine cavity. Recanalization or formation of tuboperitoneal fistulas occur, the openings of which are large enough for passage of sperm but too small to allow an ovum to push through, resulting in fertilization/implantation in the distal tubal segment. The history of tubal sterilization does not rule out the possibility of ectopic pregnancy even many years after the procedure and prophylactic bilateral salpingectomy may be considered in such cases that there is no obvious tubal lesion.
