Abstract: Fallopian tube disease is an important factor of female infertility, including proximal tubal obstruction, distal tubal occlusion, hydrosalpinx, peritubal adhesions, tubal pregnancy and sterilization. Reproductive microsurgery and in-vitro fertilization and embryo transfer (IVF-ET) technology are two treatment modalities, being complementary to each other. Tubal microsurgery should be performed by experienced surgeons in microsurgery and laparoscopy. There are seven fundamental principles of tubal microsurgery as follows: ①to ensure appropriate indications; ②to select correct patients; ③to adopt the least invasive approach; ④to use microsurgery instruments; ⑤to minimize tissue damage; ⑥to ensure precise anatomy reconstruction; ⑦to reduce complication. In this way, the benefit of tubal surgery will be maximized by cautious operation and perfect procedure.
