Accessory fallopian tube. A case report.

Accessory fallopian tubes may be found during an evaluation for infertility. The true incidence is unknown but may be as high as 6%. A patient had an ectopic pregnancy in an accessory fallopian tube; its rupture led to emergency surgery. During the next six months, five infertility patients were noted to have accessory fallopian tubes among 100 surgical infertility patients and 398 surgical gynecology patients. The accessory tubes were removed using a microsurgical technique. Three of the five patients had had prior laparoscopy, and their operative reports stated that the pelvis was normal. We suggest a careful evaluation of the pelvis in each patient. If accessory tubes are noted during surgery, one should correct the anatomy to avoid potentially life-threatening situations.
