A patient seen for infertility developed severe endometriosis within 2
years of neosalpingostomy for bilateral fallopian tube obstruction. A
retrospective review of infertility surgeries revealed none of 20 pat
ients with obstructed tubes to have endometriosis, compared with 66 of
125 (52.8%) with at least one patent fallopian tube (p < 0.001(1) 95%
confidence interval 0% to 17% vs 44% to 62%).
