    During 1969-76 77 pregnancies occurred after sterilisation in Aberdeen. The overall pregnancy rate was higher for laparoscopic sterilisation (1.2%) than for non-laparoscopic methods (0.23%), although there has been a great improvement over the past three years. The pregnancy rate was double if sterilisation was combined with termination of pregnancy, and in 30% there were surgical difficulties. Inexperienced operators were responsible for over 80% of the failures. The ectopic pregnancy rate was 15.6%.
