Minimally Invasive Management of Second Trimester Placenta Percreta

To describe the diagnostic and surgical challenges in the management of second trimester placenta percreta.Stepwise demonstration of the surgical technique with the use of an educational video.Second trimester placenta percreta is a rare entity, with very few case reports in the literature. Our video demonstrates the challenges of a minimally invasive approach toward definitive surgical management with hysterectomy. A 39-year-old G7P3 (3 previous cesarean deliveries) female at 17 weeks and 2 days gestation presented with acute abdominal pain to a community hospital. This was a spontaneously conceived pregnancy. Her hemoglobin level on admission was 92 g/L. An ultrasound showed a normal uterus, and the appendix was not visualized. One unit of packed red blood cells was transfused, and she underwent exploratory laparoscopy for a possible retrocecal hematoma/mass seen on computerized tomography. In the operating room, acute hemoperitoneum was visualized with placenta-like tissue invading through the anterior lower uterine segment (Figures 2 & 3). A hemostatic agent (Floseal, Baxter) was placed over the bleeding, and she was then transferred to a tertiary academic center for further management.Magnetic resonance imaging was performed on the following day after transfer to our facility, which confirmed placenta percreta at the level of the bladder (Figure 1). Following counseling with a multidisciplinary team and given that there was ongoing bleeding from the invading placental tissue, pregnancy continuation and uterine conservation were not possible. The patient was offered preprocedure termination of pregnancy with intra-cardiac injection of potassium chloride and 350 cc of amniotic fluid was drained at that time. This was done to facilitate visualization for a minimally invasive approach. We describe 5 main challenges of minimally invasive hysterectomy for placental percreta and provide a stepwise approach to mitigating them: visibility, vascular control, bladder dissection, colpotomy, and specimen retrieval. We adapted the previously described laparotomy techniques of progressive uterine devascularization and approach to bladder dissection and colpotomy to laparoscopy [1,2]. In addition, we performed dilatation and evacuation to allow for vaginal specimen removal. The patient's postoperative course was uncomplicated, and she was discharged home in a stable condition.Midtrimester placenta percreta poses significant challenges in diagnosis and surgical management. Total laparoscopic hysterectomy for this condition poses unique challenges but is feasible and safe.
