title: Tubal anastomosis: pregnancy success following reversal of Falope ring or monopolar cautery sterilization.
abstract: The present study reviews pregnancy outcome following tubal anastomosis in 80 previously sterilized women. Thirty of 58 women (52%) sterilized by monopolar cautery techniques delivered a living child as compared to 19 of 22 women (86%) sterilized using the Falope ring method. Cumulative pregnancy curves were calculated for the Falope ring and cautery groups using life-table methods. Following reversal of Falope ring sterilization, the estimated cumulative probability of pregnancy 6, 12, 24, and 36 months after surgery was 28.4%, 48.8%, 69.3%, and 87.2% respectively. The corresponding estimates following reversal of cautery sterilization were lower at 6, 12, 24, and 36 months following surgery: 22.7%, 37.8%, 52.4%, and 57.9%, respectively. The ectopic tubal pregnancy and spontaneous abortion rate were higher among women sterilized with monopolar cautery. A decreased pregnancy rate was associated with ampullary-isthmic anastomosis in the cautery group; however, pregnancy was least likely to occur in women with shortened oviducts of less than 4 cm.
