Background
The effectiveness and safety of pituitrin injection coupled with hysteroscopy and suction curettage as treatment for type I cesarean scar pregnancy (CSP) have not been studied enough in the literature, by comparing it to uterine artery embolization (UAE) followed by suction curettage we aim to determine its efficacy.
Materials and Methods
Data of 53 patients (the PIT group) with type I CSP treated with pituitrin injection combined with hysteroscopic suction curettage and 137 patients (the UAE group) with type I CSP treated with UAE followed by suction curettage were collected in retrospect. The clinical data were analyzed statistically to compare the efficacy and safety between the two groups.
Results
The PIT group had a shorter duration of postoperative vaginal bleeding, postoperative hospitalization, and overall hospitalization length (
P
 < 0.05). The PIT group had lower overall hospitalization costs and a lower rate of adverse events than the UAE group (
P
 < 0.05). There was no significant difference between the two groups in terms of treatment success rate, the average length of operation, blood loss during the procedure, time when serum
β
-hCG returned to normal range, and menstrual recovery time after hospital release (
P
 > 0.05).
Conclusion
UAE and pituitrin injection followed by hysteroscopic suction curettage are good choices for type I CSP treatment. However, pituitrin injection with hysteroscopic suction curettage outperforms UAE followed by suction curettage. Thus, pituitrin injection may be an option of high priority for type I CSP.
