Hydrosalpinx and tubal torsion: a late complication of tubal ligation.

Two women who had been sterilized by tubal ligation or cautery experienced recurrent pelvic pain several years later, and cystic adnexal masses were recognized in both patients. Both patients had bilateral hydrosalpinges with unilateral torsion and gangrene. These cases suggest there may be a predisposition to hydrosalpinx and tubal torsion following tubal ligation if the fimbriated end of the fallopian tube becomes occluded. Awareness of this potential complication may lead to increased recognition and earlier intervention in patients who have undergone tubal ligation.
