Histeroscopia en el tratamiento de los pólipos placentarios

Abstract

Placental polyp is a polypoid mass due to retention of decidual or fetal placental tissue in the uterine cavity after miscarriage or parturition. The estimated incidence of retained placental tissue is approximately 1% after term delivery and is probably higher after miscarriage and preterm delivery. Clinical symptoms include heavier and longer than usual uterine bleeding and pelvic pain with or without fever, since retained products are prone to infection from the cervicovaginal flora.Diagnosis is based on clinical history and gynecological examination, ultrasound findings and confirmation of trophoblastic tissue after evacuation of the uterine cavity.The most widely used treatment option continues to be dilatation and curettage. Other options include medical treatment with oral or vaginal misoprostol, ultrasound-guided resection of retained products, hysteroscopy-controlled evacuation, and resection using a rectoscope under direct vision.We present a case series of seven patients with retained products of conception after miscarriage. The method chosen to remove these products was evacuation using a rectoscope under direct vision of the cavity. We also provide a literature review of this entity.
