Treatment for a blocked fallopian tube depends on the location of the obstruction and its cause. Surgery is often needed, but an inpatient procedure, tubal cannulation, is used in certain cases, according to WebMD.
If fallopian tubes are blocked because the tubes have been tied to prevent conception, doctors are sometimes able to reopen the pathway by tubal reanastomosis, WebMD states. The blockage is cut away, and the two sections of the tube are reconnected. This typically requires a surgical incision in the abdomen. However, certain surgeons use laparoscopy, and the surgery is done through a much smaller opening.
When the tube is blocked by fluid, a salpingectomy is sometimes performed, says WebMD, during which the troublesome part of the tube is removed. Another option to deal with fluid is a salpingostomy. In this operation, a new opening is made in the tube near the ovary. This procedure is problematic because scar tissue often forms, creating another impediment.
If the barrier forms right next to the ovary, a fimbrioplasty reconstructs the fallopian tube's opening, WebMD explains. This allows the egg to move easily from the ovary to the tube. When the blockage occurs at the other end of the tube near the uterus, a tubal cannulation is used, reports Mid-Iowa Fertility. A doctor passes a wire from the cervix to the uterus and into the fallopian tube, removing the barricade.
