A four step strategy for robot assisted abdominal cerclage placement prior to pregnancy

Abdominal cerclage assists in optimizing pregnancy outcomes among women with recurrent pregnancy loss who have had negative outcomes with alternate modalities. This video demonstrates a four-step strategy to optimize effective abdominal cerclage placement using robot-assisted technology.

To demonstrate a simple, stepwise strategy for robot-assisted abdominal cerclage placement before pregnancy.


Demonstrative video presentation. Surgical footage surrounding a case report is used to describe a four-step technique for robot-assisted abdominal cerclage placement in women with recurrent pregnancy loss or other anatomic variants before pregnancy. This video article was reviewed by the Investigational Review Board and further investigation was waived because the study was “not considered human subject research.”


Tertiary medical center.


A 38-year-old G4P0220 (Gestations: 4, Term deliveries: 0, Preterm deliveries: 2, Abortions: 2, Living children: 0) with a history of two second trimester losses who had failed a prior history-indicated transvaginal cerclage (Fig. 1).


The patient underwent an uncomplicated robot-assisted abdominal cerclage using a four-step strategy: Step 1, create the bladder flap; Step 2, identify pertinent anatomy; Step 3, place the cerclage; and Step 4, hysteroscopy.

Main Outcome Measure(s)

Intraoperative technique presenting a four-step method to ensure successful robot-assisted abdominal cerclage placement.


Robot-assisted abdominal cerclage is a safe, viable alternative to traditional abdominal cerclage placed via laparotomy. This video outlines four critical steps to facilitate placement and decrease patient morbidity. This patient did well operatively without increased blood loss or operative time and was discharged home on postoperative day 1. She went on to have a successful future pregnancy and currently is scheduled for an elective cesarean section at term.


Abdominal cerclages significantly improve pregnancy and neonatal outcomes in women who previously have failed transvaginal cerclage. Robot-assisted abdominal cerclage placement allows a minimally invasive approach with enhanced dexterity and better visualization for the surgeon compared with conventional laparoscopy or laparotomy, as well as decreased pain and shorter recovery time for patients. This video demonstrates placement of a robot-assisted abdominal cerclage in a patient with recurrent pregnancy loss using a simple four-step strategy to ensure successful, correct, and easy placement. To our knowledge, this is the first video demonstrating a stepwise approach to robot-assisted abdominal cerclage placement.
