Fallopian tube prolapse into the vaginal vault is a rare complication after hysterectomy with adnexal preservation. It can occur following vaginal and abdominal hysterectomy, and rarely following interposition and colpotomy. Histopathology is the only means of definitive diagnosis. Prevention of tubal prolapse can be achieved by suturing the adnexae high in the pelvis at abdominal hysterectomy, and the incidence decreases if the pelvic peritoneum is closed properly.
