The paper reports two pregnancy case reports in women who previously underwent laparoscopic myomectomy, with one also having resection of adenomyosis, and who were later diagnosed with placenta accreta during pregnancy. In both cases, prenatal assessment with ultrasonography (with MRI in the first case) showed findings consistent with accreta—thin uterine posterior wall with placental invagination at 33 weeks in the first case, and placental accreta at 35 weeks in the second—followed by cesarean delivery where the uterine muscular layer required repair or partial resection at the time of placental removal. The major limitation is that this is a small, descriptive case report series without broader study design or comparative analysis. This paper is centrally about adenomyosis and endometriosis in the sense that it describes placenta accreta occurring in pregnancies after laparoscopic myomectomy plus adenomyosis resection (adenomyomectomy), documenting a specific post-adenomyosis-surgery obstetric complication.

Abstract

We report two cases of placenta accreta identified during pregnancy after laparoscopic surgery. The first case involved a 39-year-old woman with a history of miscarriage. Ultrasonography and MRI revealed multiple uterine myomas and adenomyosis. One year after laparoscopic myomectomy and adenomyosis resection, ultrasonography at 33 weeks of gestation revealed a thin uterine posterior wall and placental invagination, indicating placenta accreta. During cesarean section, the muscular layer required repair after removal of the placenta. The second case involved a 37-year-old woman with excessive menstruation. Ultrasonography revealed a large uterine myoma adjacent to the endometrial cavity. Four years after laparoscopic myomectomy, ultrasonography revealed placenta accreta at 35 weeks of gestation. During cesarean section, the muscular layer needed to be partially resected together with the placenta. A thorough placental evaluation with ultrasonography is recommended in pregnancies achieved after myomectomy and adenomyosis resection.
