Minimally Invasive Surgical Options for Congenital and Acquired Uterine Factors Associated with Recurrent Pregnancy Loss

Abstract

Recurrent pregnancy loss (RPL) is defined as two or more failed clinical pregnancies before 20 weeks' gestation and may be caused by genetic, endocrinologic, anatomic and immunologic abnormalities. Anatomic uterine anomalies include congenital malformations (bicornuate, didelphic, septate and unicornuate uteri) and acquired defects (fibroids, adenomas, adhesions and polyps). Women with septate and bicornuate uteri, intrauterine adhesions, and some adenomas and fibroids are at increased risk of RPL. Data support surgical treatment of all of these lesions except bicornuate uteri. The role of polyps in RPL is unclear. Minimally invasive options for surgical correction of intrauterine lesions include hysteroscopy, laparoscopy with and without robotic assistance and minilaparotomy.
