Infertility Treatment - Endometriosis

The success rates following tubal surgery will depend on the severity of the disease. Careful pre-operative assessment, including semen analysis and often hysterosalpingography and laparoscopy, is required.

The commonest site of tubal damage is at the fimbrial end (opening near the ovaries –Figure 9.1), with birth rates after surgery in the order of 25 per cent. Surgery for proximal tubal occlusion (the blockage is close to the uterus) is more successful, with live birth rates of 50% and ectopic rates of 10%. Just over a half of intrauterine pregnancies following tubal surgery may occur more than one year after surgery. Reversal of sterilisation, with removal of clips and re-anastomosis (reconnection), carries a relatively high success rate of up to 80%.

Tubal microsurgery involves the use of magnification as well as the adoption of a set of techniques including the use of special instruments, minimal handling of the Fallopian tubes and fine non-reactive suture material. There have been no controlled trials to prove conclusively an advantage over conventional surgical techniques but several surgical teams have reported improved success rates. It is technically possible to transplant Fallopian tubes and large numbers of these organs would undoubtedly be donated by women undergoing sterilisation or hysterectomy(hysterectomy). Research interest in this area seems to have diminished following the development of IVF (Q10.24).
