Tubal conservation in ectopic pregnancy: a study of 200 cases.

There have been 1152 cases of ectopic pregnancy at Kaiser Permanente Hospital from 1953 to 1980. In 200 cases the involved tube was preserved with no surgical complications. There have been 122 subsequent pregnancies, 24 of which were repeat ectopic pregnancies. Twelve were in the involved tube and 12 were in the opposite tube, demonstrating conclusively that both tubes are at equal risk of ectopic pregnancy. Conserving the involved tube does not increase the incidence of ectopic pregnancy but does increase the chances for intrauterine pregnancy in this subfertile population.
