[Tubo-peritoneal factor of infertility: diagnosis and treatment].
Infertility, defined as the inability to conceive despite regular unprotected sexual intercourse over 12 years, affects approximately 10% of the fertile population. The commonest cause of tubal damage is pelvic inflammatory disease (PID), which in the developed world is caused mainly by Chlamydia trachomatis infection. The incidence of tubal damage after one episode of pelvic infection is approximately 12%, 23% after two episodes and 54% after three episodes. Other causes of tubal damage include postsurgical adhesions or endometriosis. Tubal patency can be diagnosed by hysterosalpingography (HSG) or laparoscopy with chromopertubation. Surgery represents the best therapeutic approach for tubal pathology, with a term pregnancy rate of 70% after surgery in selected patients, while the latest results in Italy of assisted reproductive technology (ART) report a live birth rate per cycle of 13.8%. In conclusion, tubal reconstructive surgery remains an important option for many couples and surgery should be the fi rst line approach for a correct diagnosis and treatment of tubal infertility.
