Combined Medical and Minimally Invasive Robotic Surgical Approach to the Treatment and Repair of Cesarean Scar Pregnancies.

BACKGROUND AND OBJECTIVES: The rise in cesarean deliveries, has led to increase in maternal complications in subsequent pregnancies such as abnormal placental implantation, uterine rupture, hemorrhage and, less commonly, cesarean scar pregnancies (CSP). Our objective was to describe patient characteristics following a combined medical and surgical treatment approach to first trimester cesarean scar pregnancies. METHODS: This was a case series approved by the Institutional Review Board of cesarean scar pregnancies over a two-year period at a single academic institution. The study included five patients with diagnosed cesarean scar pregnancies opting for pregnancy termination with the desire for fertility preservation. Medical treatment involved intra-gestational sac injection of lidocaine followed by systemic injection of methotrexate. At a minimum of two months later, surgical resection of cesarean scar pregnancy and repair of the uterus was performed. RESULTS: Median patient age was 36 (range 34 - 42) years, with 4 (3 - 10) prior pregnancies and 2 (1 - 3) prior cesarean deliveries. 40% (2/5) were Hispanic, 20% (1/5) Caucasian, 20% (1/5) African-American, and 20% (1/5) South Asian. After medical intervention, patients waited on average 4.6 ± 2.3 months before surgery. No post-intervention complications or recurrences occurred. Two patients had a subsequent pregnancy. CONCLUSION: This case series demonstrates an ideal management of cesarean scar pregnancy using combined medical and surgical approach in treating current ectopic pregnancy and repairing the uterine defect successfully without recurrence.
