Tubal pregnancy is the most common type of ectopic pregnancy and one of the most common acute abdominal diseases in obstetrics and gynecology, which seriously threatens women’s life and reproductive health. At the same time, most patients with ectopic pregnancy are young women of reproductive age, and the proportion of unmarried and infertile patients has increased significantly, most of whom need to preserve their fertility. The evaluation of the effectiveness of the treatment of tubal pregnancy is based on the reproductive status and complications. The indicators of reproductive status include intrauterine pregnancy rate and full-term live birth rate; complications include persistent ectopic pregnancy and recurrent ectopic pregnancy. However, whether treated conservatively or surgically, due to the tubal pregnancy itself and other coexisting factors, patients are significantly less likely than normal women to obtain an intrauterine pregnancy after treatment, while the chances of repeat ectopic pregnancy and infertility increase significantly; overall, infertility can occur in about 20-60% of cases after ectopic pregnancy. Therefore, for patients with ectopic pregnancy who have fertility requirements, it is necessary to provide guidance on fertility assessment before reproduction, to choose a simple, minimally invasive and effective evaluation method to assess the tubal function and pelvic status of patients after ectopic pregnancy treatment, and to guide them to obtain the next normal intrauterine pregnancy, thus improving their reproductive prognosis. Factors affecting reproductive status after tubal pregnancy treatment 1. Age: the intrauterine pregnancy rate within 1 year in patients aged ≤24 years is 65%, much higher than 37% in patients >35 years; 2. Fertility history: previous history of infertility is the most important factor affecting reproductive outcome after treatment; 3. Contralateral tubal condition: it is an important factor affecting reproductive outcome after treatment. Pelvic inflammatory disease, infertility, ectopic pregnancy, tubal surgery, and tubal adhesion atresia are risk factors for postoperative infertility and recurrent ectopic pregnancy after tubal pregnancy. For ectopic pregnancy patients with fertility requirements, it is necessary to conduct fertility assessment guidance before reproduction after ectopic pregnancy treatment, evaluate the tubal function and pelvic status of patients, apply appropriate assisted reproduction means if necessary, and release contraception as early as possible when the tubes are patent to prevent potential inflammation in the pelvis for too long from re-emerging and aggravating, pelvic adhesions, affecting tubal peristalsis leading to infertility or ectopic pregnancy. 4. After ectopic pregnancy: natural intrauterine fertilization occurs within 1 year at most, and the chance of pregnancy is significantly reduced if natural intrauterine fertilization cannot occur within 2 years. Evaluation of tubal function before preparation for childbirth: For many years, the common method of evaluating tubal function is hysterosalpingography (HSG), but the sensitivity of HSG in diagnosing tubal lesions is low, and the accuracy of diagnosing pelvic and peritoneal lesions is not high, especially for the lack of understanding of adhesions around the fallopian tubes and ovaries and the pelvic cavity, which is very important for clarifying the cause of infertility and choosing the appropriate treatment. This information is very important in determining the cause of infertility and choosing the appropriate treatment. Combined hysterolaparoscopic surgery is the gold standard for evaluating tubal patency. Standard laparoscopy is performed with CO2 as the medium to enter the abdominal and pelvic cavities through the abdominal wall, which allows direct observation of lesions in the pelvic and abdominal cavities, and can diagnose pelvic inflammatory disease, endometriosis, ovarian tumors, polycystic ovary syndrome, tubal obstruction, etc. Microscopically, it can separate pelvic adhesions, electrocautery of ectopic lesions, ovarian perforation, uterine and ovarian tumor removal, etc. It has the advantages of being accurate and minimally invasive in infertility screening and has an irreplaceable role.
