[Falloposcopy--a new method for evaluation and treatment of infertility due to tubal factors]

Tubal factors cause infertility in about a third of cases. With current diagnostic techniques, such as laparoscopy and hysterosalpingography, only a fraction of the causes of tubal infertility can be diagnosed and in many cases misdiagnosis results. Newer methods, such as ampullosalpingoscopy enable examination of the fimbria and ampullar segment of the fallopian tube, but the examination of the proximal tube, in which 10-20% of occlusions occur, is still impossible. We describe a new diagnostic technique, falloposcopy. It involves the transuterine insertion of a fiber optic device into the fallopian tube through a hysteroscope. This technique enables direct visualization of all segments of the fallopian tube, as well as removal of intratubal debris or adhesions. Using falloposcopy, a new grading method for tubal disease has been developed. We describe the results of 129 falloposcopic procedures in 82 women. Following falloposcopy, women with mild to moderate disease, according to the new classification, have conceived without further therapy during a follow-up period of up to 3 years. Falloposcopy may aid in differentiating between patients suitable for tubal surgery and those who should be referred for in vitro fertilization.
