Objective::To compare the efficacy and safety of four surgical strategies currently used for the management of deep implantation cesarean scar pregnancy (CSP-II).Methods::This was a retrospective clinical cohort study, and, in total, 131 women diagnosed with CSP-II and primarily treated in our hospital were recruited. Women treated using laparoscopy assisted by operative hysteroscopy (LAOH; Group A,
n = 25), uterine artery embolization (UAE) followed by LAOH (Group B,
n = 21), ultrasound-guided dilatation and curettage (D&C; Group C,
n = 24), and UAE followed by D&C (Group D,
n = 61) were evaluated. Univariate and multiple logistic analyses were performed to identify the risk factors.
Results::No statistically significant difference was found in patient age, gestational age, size of lesion, and pretreatment serum β-human chorionic gonadotropins (β-hCG) level. Operation time was longer (
P < 0.001) and the success rate was higher (
P = 0.01) in both Group A and Group B than in Group C and Group D. When the cohort was further analyzed regarding patients with myometrial thickness ≤3 mm (
n = 75, defined as CSP-IIb), a lower rate of perioperative complications (
P = 0.036) and a higher success rate (
P < 0.001) remained in Group A (
n = 15) and Group B (
n = 15) but not in Group C (
n = 11) or Group D (
n = 34). In multiple logistic regression analysis, the risk factors related to lower treatment efficacy for patients with CSP-II were thinner myometrial thickness of cesarean scar (CS) (≤3 mm) (odds ratio [
OR] = 5.470,
P = 0.062), number of cesarean sections (a2) (
OR = 8.877,
P = 0.013), mass protruding into the bladder or abdominal cavity (
OR = 25.507,
P < 0.001), and direct D&C modality (
OR = 38.247,
P = 0.010).
Conclusions::Compared with D&C ± UAE, LAOH ± UAE showed a higher success rate for patients with CSP-II, especially when the zygote was more deeply implanted with a myometrial thickness of CS ≤ 3 mm. CSP-II treatment should be individualized on the basis of many risk factors.
