In late 2013, a public awareness campaign was initiated after electromechanical morcellation (EMM) of a uterus with presumed benign leiomyoma, which in fact was leiomyosarcoma (LMS). Over the past year, the focus of the medical community has been on the incidence of occult LMS, specifically related to EMM. The risk of intracorporeal tissue dissemination by EMM resulted in some manufacturers halting sales of the EMM device, various hospitals banning the procedure, and ultimately a black box warning from the US Food and Drug Administration (FDA) for electromechanical morcellators. 1 This type of issue is not new in medicine. In the 1950s and early 1960s, laparoscopic surgery was banned in Germany owing to electrosurgical complications during laparoscopic sterilization. 2 This led to greater understanding of sparking, capacitation, and coupling related to electrosurgery during laparoscopy; subsequent technological improvements and surgeon education resulted in electrosurgery being an integral part of minimally invasive surgery today. Albert Einstein defined insanity as doing the same thing over and over again and expecting different results. As with electrosurgery, EMM needs reassessment and improvement in technique and instrumentation for proper use. Systematic literature reviews, 3 reports from multispecialty centers, 4 and large group studies 5 have mainly focused on hysterectomy patients with estimations of uterine sarcoma relating primarily to symptomatic women requiring hysterectomy. This methodology overlooks a large data set of patients undergoing myomectomy to restore anatomy and preserve and enhance fertility. 6 Worldwide, thousands of myomectomies are performed vaginally or by minilaparotomy, conventional laparotomy, laparoscopy, or hysteroscopy, primarily in women of reproductive age for subfertility. While EMM is used mostly during laparoscopic myomectomies, with or without robotic assistance, the impact and outcome of tissue disruption at the time of myomectomy by any method, including laparotomy, carries a small risk of intraperitoneal dissemination of occult malignant tissue. In this issue of JAMA Oncology, Wright and colleagues 7 report their analysis concerning the prevalence of undetected cancer and precancerous changes in women who underwent myomectomy with and without EMM. In light of the limited data regarding safety and risks in women undergoing myomectomy with EMM, this report broadens the focus on this matter. Owing to lack of information regarding the risk of occult uterine malignant neoplasms in reproductive-age women and possible tumor dissemination during myomectomy, with or without morcellation, the magnitude of harm is unknown. Consequently, not only morcellation, but the Related article page 69
