Surgical and Obstetric Complications of Transabdominal Cervical Cerclage by Laparoscopic, Open, and Robotic Approaches: A Systematic Review and Meta-Analysis. Marchand GJ, Gonzalez Herrera D, Robinson M, O’Connell B, Anderson D, Mera S, Palma A, Ibrahim F, Azadi A. Am J Obstet Gynecol. Article in Press, November 1, 2026. DOI 10.1016/j.ajog.2026.10.040.
The biggest paper of Dr. Marchand’s career and the largest body of patients ever assembled on transabdominal cerclage: 63 studies, 70 study arms and 5,094 women, and the first analysis restricted to within-study comparisons of the laparoscopic, open and robotic routes. Across the six head-to-head studies and 317 pregnancies, no difference was detectable in any complication. Major hemorrhage and uterine perforation were uncommon after laparoscopic placement, with no major hemorrhage in 1,889 laparoscopic procedures; pregnancy loss was not uncommon, and no route was shown to be safer than another. The advantage reported in earlier reviews, which compared two separately pooled literatures, does not reproduce when the routes are compared inside the same studies.
