A multicentre trial was conducted to compare efficacy of postpartum sterilisation with clip and partial salpingectomy. Life-table estimates of pregnancy probabilities were compared through 2 years of follow up. A significantly different risk of pregnancy between the clip and partial salpingectomy groups was observed. Nine pregnancies were observed in the clip group versus two in the partial salpingectomy group. Cumulative probability of pregnancy through 2 years was 0.017 with the clip and 0.004 [correction added after online publication 25 September 2012; 0.044 has been replaced with 0.004] for partial salpingectomy (P < 0.04). Equivalent efficacy of the clip compared with partial salpingectomy has not been demonstrated in postpartum women.
