The Selection of Pregnancy for Patients After Tubal Ectopic Pregnancy Treatment (TSOPFPATEPT)

The Selection of Pregnancy for Patients After Tubal Ectopic Pregnancy Treatment In Pudong New Area

The incidence of re-ectopic pregnancy in patients with tubal ectopic pregnancy increases significantly, which may be related to the condition of the fallopian tubes, such as tubal inflammation, tubal obstruction and other high-risk factors that may lead to tubal ectopic pregnancy; it is also associated with the treatment of the previous tubal ectopic pregnancy. Compared with salpingectomy, the treatment of preserving the fallopian tubes increased the incidence of re-ectopic pregnancy while increasing the pregnancy rate of the patient. For tubal-preserving patients, the most common option currently used is to recommend that monitoring ovulation during each menstrual cycle if they choose to conceive naturally rather than IVF. If ovulation occures on the healthy side of the ovary, it may be considered to try to conceive; Otherwise, contraception is recommended. However, there are uncertainties about this option. Based on this, we intend to conduct a multicenter clinical trial to verify the effectiveness of the ovulation preparation regimen on the healthy side of ovary.

Detailed Description

Tubal ectopic pregnancy is a disease that seriously affects women's physical and mental health and reproductive health, not only can there be some short-term complications such as rupture of tubal pregnancy and massive bleeding in the abdominal cavity, but also can lead to a decrease in female fertility, and the incidence of subsequent ectopic pregnancy has increased significantly. In recent years, with the development of diagnosis and treatment methods, the proportion of serious clinical events such as rupture of tubal pregnancy and massive hemorrhage in patients has decreased significantly. However, there is little research on the long-term damage of tubal pregnancy to women's fertility, especially how to avoid the occurrence of re-ectopic pregnancy, and there is no definitive and effective program.The incidence of re-ectopic pregnancy in patients with tubal ectopic pregnancy increases significantly, which may be related to the condition of the fallopian tubes, such as tubal inflammation, tubal obstruction and other high-risk factors that may lead to tubal ectopic pregnancy; it is also associated with the treatment of the previous tubal ectopic pregnancy. Compared with salpingectomy, the treatment of preserving the fallopian tubes increased the incidence of re-ectopic pregnancy while increasing the pregnancy rate of the patient.It is reported that the incidence of re-ectopic pregnancy in patients who choose salpingotomy is significantly higher than salpingectomy.Patients receiving conservative treatment and expectant treatment with methotrexate have a similar incidence of re-ectopic pregnancy as in patients receving salpingotomy.For tubal-preserving patients, the most common option currently used is to recommend that monitoring ovulation during each menstrual cycle if they choose to conceive naturally rather than IVF. If ovulation occures on the healthy side of the ovary, it may be considered to try to conceive; Otherwise, contraception is recommended. However, there are uncertainties about this option. Based on this, we intend to conduct a multicenter clinical trial to verify the effectiveness of the ovulation preparation program on the healthy side of ovary.We plan to randomly divide patients who meet the inclusion criteria into two groups:preparation for pregnancy in each ovulatory cycle and in healthy ovulatory cycle. Monitor the development of the patient's follicles each cycle, follow the patient to pregnancy, and analyze the patient's ovulation rate of healthy ovary, pregnancy rate, ectopic pregnancy rate and the time required from preparation to be pregnant, so as to determine whether the healthy side ovulation preparation program can improve the patient's normal pregnancy rate and reduce the ectopic pregnancy rate.

Cohorts and Interventions

Group / Cohort	Intervention / Treatment
Ovulation occurs on the healthy side; In tubal-presering patient who received treatment of tubal ectopic pregnancy,only when ovulation occurs on the healthy side of ovary,it may be considered to try to conceive; otherwise, contraception is recommended.	Other: No intervention.; No intervention.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rate of tubal pregnancy within12 months in both groups of patients.	Tubal ectopic pregnancy refers to the implantation of embryo in the fallopian tubes.	2023.10

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Rates of pregnancy and miscarriage within 12 months in both groups of patients.	Clinical pregnancy is defined as ultrasound suggesting a gestational sac, with or without fetal heartbeat; miscarriage is defined as ultrasound suggesting that the fetus is inanimate or that the fetus has miscarried spontaneously.	2023.10
