Abstract:

Objective

To study the risk factors leading to type II/III cesarean scar pregnancy and evaluate the efficacy of hysteroscopic treatment and subsequent reproductive outcomes.


Design

Retrospective study from 2013 to 2018.


Setting

Inpatient samples.


Patient(s)

A total of 439 patients with cesarean scar pregnancy received hysteroscopic treatment. They were grouped according to the type of surgery as hysteroscopy combined with dilation and curettage, systemic methotrexate followed by hysteroscopy combined with dilation and curettage, and uterine artery embolization or laparoscopic ligation of bilateral uterine arteries followed by hysteroscopy combined with dilation and curettage. Cesarean scar pregnancy was classified as types I, II, and III on the basis of the relationship between the gestational sac and myometrial thickness by ultrasound.


Intervention(s)

Not applicable.


Main Outcome Measure(s)

Risk factors leading to type II/III cesarean scar pregnancy. The success of hysteroscopic treatment as well as favorable reproductive outcomes.


Result(s)

The significant variables were multiple parity, prior cesarean section (CS), hysteroscopic therapy, and dilation and curettage after the last CS between type I and type II/III. There were significant differences among the three groups in symptoms, largest diameter of the gestational sac, presence of fetal heartbeat, myometrial thickness, type of cesarean scar pregnancy, blood loss, length of hospital stay, and expense. The rates of complications and success were 8.2% and 93.6%, respectively. Thirty-seven women conceived again, and 22 women completed a term pregnancy with no uterine rupture. The recurrence rate of cesarean scar pregnancy was 10.8%.


Conclusions

The type of cesarean scar pregnancy is related to the rates of multiple parity, cesarean deliveries, and dilation and curettage procedures after the last CS. Hysteroscopic therapy is a safe and effective surgical approach with a low risk of subsequent ectopic pregnancy.
