Abstract: Surgery is the main effective method for the treatment of fallopian tube occlusion. Hysteroscopy and laparoscopy lead the treatment of tubal infertility into the era of minimally invasive surgery. The accurate evaluation of tubal function helps to analyze the causes of infertility, which provides important clinical evidence for treatment. Laparoscopic, ultrasonographic examination and hysterosalpingography are useful methods to evaluate the status of fallopian tube. The development of 2D hysterosalpingo-contrast-sonography(2D-HyCoSy), 3D-HyCoSy and 4D-HyCoSy technologies make the evaluation of tubal lesion more accurate by observing the dynamic change of fallopian tube. The treatment of distal tube obstruction includes salpingostomy, salpingectomy, proximal tubal block, tubal embolization under hysteroscope, fimbrioplasty, proximal tubal block and salpingostomy for distal tube, under the guidance of ultrasound hydrosalpinx suction sclerosis therapy, and so on, all of which have their own indications. Tubal cannulation technique is an effective method for the treatment of proximal tubal obstruction, which is operated by means of laparoscopy, hysteroscopy, ultrasonography or radiation guidance. The combination of laparoscopy with hysteroscopy in the tubal cannulation is the most common method, which makes it to be possible to diagnose and treat simultaneously pelvic adhesions and endometriosis. In vitro fertilization is a complementary treatment of tubal surgery for infertile women with tubal occlusion. Falloscopy, robotic and 3D laparoscopy as well as COOK guide-wire are increasingly used in tubal reconstructive surgery, which are expected to increase the pregnancy rate.
