Pregnancy following tubocornual anastomosis.

We have reviewed the pregnancy rate and outcome of 25 patients who underwent tubocornual anastomosis for correction of proximal tubal occlusion at Yale-New Haven Hospital between 1977 and 1981. Tubal occlusion was the result of previous tubal sterilization in 17 patients (11 laparoscopic electrocautery and 6 tubal ligation) and previous tubal infection in 8. Fourteen of the patients conceived (56%). Viable pregnancy was achieved in nine patients (36%) and tubal pregnancy in three (12%). No significant difference in pregnancy rates was found between patients with diseased cornua and those previously sterilized by either electrocautery or tubal ligation. Tubal length of greater than or equal to 4 cm following corrective surgery as compared with less than or equal to 4 cm did not influence pregnancy rates. The patients with the shorter oviducts had a higher rate of early pregnancy wastage. All three tubal pregnancies occurred in patients with reoccluded fallopian tubes as demonstrated by a hysterosalpingogram. We conclude that tubocornual anastomosis still remains the treatment of choice for patients with proximal tubal obstruction.
