Reconstructive Tubal Surgery

With the availability of and improvements in in vitro fertilization (IVF), the role of reproductive surgery has been questioned. Yet, the scope of reproductive surgery today is much larger than in the past. Hysteroscopic correction of intrauterine disease is an important endoscopic procedure in women with infertility. Evidence suggests that correction of intrauterine disease is often followed by spontaneous pregnancy and improved IVF outcome. Hysteroscopic examination should be considered after 1 failed IVF. Today, it is clear that removal of the hydrosalpinx leads to a higher IVF-related live birth rate. The procedure should be performed thoroughly without compromising the ovarian blood supply. The IVF pregnancy rate is not affected by the presence of ovarian endometriomas, and small endometriomas need not be removed; however, large and symptomatic endometriomas that interfere with oocyte retrieval should be excised. When excision of the cyst wall is difficult, fenestration and ablation should be considered. This might lead to an increased recurrence rate, but is associated with less interference of the ovarian reserve. Although the role of reproductive surgery as primary treatment for tuboperitoneal infertility is limited, it has an important role in enhancing the outcome of IVF treatment and in preservation of fertility. Surgical preservation of fertility consists of ovarian suspension, ovarian excision for cryopreservation, and ovarian tissue transplantation.Assisted reproductive techniques yield high rates of success for women with tubal factor infertility.

Because they are potentially effective for all categories of infertility, for two decades, clinical and basic research in infertility has been focused on IVF techniques and outcomes, rather than developing surgical techniques or training infertility subspecialists in tubal microsurgery. Nonetheless, in comparison with IVF, reconstructive tubal surgery is inexpensive and offers multiple opportunities to attempt conception. Performing laparoscopic salpingostomy prior to IVF in women with good prognosis tubal disease may improve the outcome of subsequent IVF, while offering the potential for spontaneous conception. Tubo-tubal anastomosis for reversal of tubal ligation, performed either by a microsurgical technique through a mini-laparotomy or by laparoscopy, is preferable to IVF in younger women with no other fertility factors, because it offers potentially higher cumulative pregnancy rates. Surgery is the only alternative for women with tubal factor infertility who for personal or other reasons are unable to undergo assisted reproductive techniques. Tubal reconstructive surgery and assisted reproductive techniques must be considered complementary forms of treatment for women with tubal factor infertility, and training in tubal reconstructive surgery should be an integral part of subspecialty training in reproductive endocrinology and infertility.
