[A study of the prognosis at one year after restorative tubal surgery in the treatment of sterility (author's transl)].

A cooperative study has been carried out on 301 women who were operated on for tubal sterility in 9 centres in different countries between 1969 and 1974. 19 per cent of these started an intra-uterine pregnancy and 4 per cent an extra-uterine pregnancy during the first year they were followed up. The results reaffirm the poor prognosis of genital tuberculosis, of tubal blocks found on hysterosalpingography and of adhesions discovered on laparoscopy. If the type of operation has little relationship to the results, these do change according to the treatment given around the time of operation. There were more intra-uterine pregnancies in women who had treatment systemically with corticoids and with antibiotics than in those who only had corticotherapy locally. This result has been confirmed when results have been compared taking into account the Centre where the operation was carried out and the type of lesions that were discovered on hysterosalpingography and on laparoscopy.
