Summary: Ninety-four patients with tubal factor
infertility were studies to determine whether proximal tubal cauterization is an
effective method of reversing the decreased pregnancy rates seen in patients
undergoing in vitro fertilization-embryo transfer with hydrosalpinges present.
Forty-five patients had surgical treatment of hydrosalpinges by salpingectomy or
by proximal tubal cauterization. In vitro fertilization-embryo transfer was
performed within 3 months after surgery. Patients wit hydrosalpinx had
significantly decreased clinical pregnancy and implantation rates per cycle (14%
and 8%, respectively) compared with those of patients undergoing proximal tubal
cauterization before the in vitro fertilization cycle (73% and 36%,
respectively). These pregnancy and implantation rates are comparable with those
found in patients with tubal factor infertility without hydrosalpinges (53% and
22%, respectively), as well as in salpingectomy-treated patients (46% and 24%,
respectively). Researchers concluded that proximal tubal cauterization is
effective in reversing the adverse effects of hydrosalpinges.
Comment: We now know without a doubt that hydrosalpinges are
associated with a significant reduction in pregnancy rate after IVF. It appears
that correction of hydrosalpinges (removal of the tubes) improves success. In
some cases, removal of the tube, especially when involved with a tubo-ovarian
complex, can be difficult and could lead to alteration in the blood supply of the
ovary. The above report concludes that a procedure equivalent to tubal
sterilization without removal of the entire tube is effective therapy. I continue
to believe that if severe tubal disease is found at a diagnostic laparoscopy that
there should be definitive action taken to avoid another surgery. It is very
difficult to include this in all preoperative consents for laparoscopy, but is
probably best.
