Adhesions after Laparoscopic Myomectomy: Incidence, Risk Factors, Complications, and Prevention.

Uterine fibroids or uterine myomas are one of the most common benign diseases of the uterus. Symptoms associated with myomas can make surgical removal of myomas necessary. Besides the traditional abdominal route, laparoscopic myomectomy (LM) has gained more acceptances over the last few decades, and it is anticipated that laparoscopy is associated with lower adhesion development. Therefore, we conducted this review to analyze the evidence on adhesions after LM. The PubMed database was searched using the search terms "myomectomy" alone and in combination with "adhesions," "infertility OR fertility outcome," and "laparoscopy" among articles published in English and German. Although the well-known advantages of laparoscopy, for example, less pain, less blood loss, or shorter hospital stay, myomectomy belongs to high-risk operations concerning adhesion formation, with at least every fifth patient developing postsurgical adhesions. In laparoscopic surgery, surgeons´ experience as well tissue trauma, due to desiccation and hypoxia, are the underlying mechanisms leading to adhesion formation. Incisions of the posterior uterus may be associated with a higher rate of adhesions compared to anterior or fundal incisions. Adhesions can be associated with severe complications such as small bowel obstruction, chronic pelvic pain, complications in further operations, or impaired fertility. Tissue trauma and the experience of the surgeon in laparoscopic surgery are most of the influencing factors for adhesion formation after myomectomy. Therefore, every surgeon should adopt strategies to reduce adhesion development in daily routine, especially when it conducted to preserve or restore fertility.
