Iatrogenic parasitic myoma and iatrogenic adenomyoma after laparoscopic morcellation: A mini-review

Laparoscopy is widely recognized as a procedure of choice for gynaecological surgery. Myomectomy and hysterectomy are the most frequently performed surgical procedures in gynaecology. A morcellator is often used in myomectomies or subtotal hysterectomies, but morcellation may cause rare complications, such as parasitic iatrogenic myoma or adenomyoma. To improve patient counselling, proper risk estimation as well as risk factor identification should be acknowledged. This article aimed to review the literature on parasitic myoma and adenomyoma and to compare these diseases in terms of clinical, surgical, and prognostic factors. All published literature (case series and case reports) on iatrogenic myoma and adenomyoma was reviewed using PubMed/MEDLINE and ScienceDirect resources. Despite both conditions having an iatrogenic origin, iatrogenic parasitic myoma and adenomyoma are two different entities in terms of clinical manifestations as well as intraoperative particularities, with a common point: iatrogenic complication. A possible solution to avoid these iatrogenic complications is by using in-bag morcellation or switching to another surgical procedure (e.g., a vaginal or abdominal approach). It is concluded that parasitic myoma and iatrogenic adenomyoma are two different iatrogenic morcellator-related complications. In patients with a history of uterus or myoma morcellation who report pelvic symptoms, iatrogenic parasitic myoma or adenomyoma should be considered in the differential diagnosis.
