This study indicates the relationship between tubal sterilization and pelvic venous stasis syndrome. Exploratory laparatomy was performed in 24 patients with symptoms of lower abdominal pain and intercourse pain after tubal ligation who had failed to respond to medical treatment for a long time. During the operation the author found that the venous vessels within the mesosalpinx had enlarged with hyperemia and varicosities in 17 cases. All of them got satisfactory effects after operative therapy. The etiology, prevention, and treatment of this syndrome following tubal sterilization are discussed and emphasis is laid on how to take precautions against pelvic venous stasis during tubal ligation.
