Characterization and mitigation of stray radiofrequency currents during monopolar resectoscopic electrosurgery

Electrosurgery and clinical applications of electrosurgical devices in gynecologic procedures

Background: Electrosurgery is widely used in reproductive related surgeries and technological advancements to improve efficacy and reduce potential complications. However, some reports have indicated lack of sufficient knowledge and training about basic principles and technical aspects of electrosurgery among obstetricians and gynecologists.

Methods: In this paper we present a summary on basic concepts and principles of electrosurgery and review the recent evidence on the use of electrosurgical devices in gynecologic procedures including endometrial ablation, gynecologic malignancies, loop electrode excision procedure (LEEP), and infertility.

Result: Considering the extensive use of these technologies in reproductive related surgeries, procedures including laparoscopy, hysteroscopy, and loop procedures further highlights the importance of more detailed training in this field. Gynecologists must learn the basics in more detail and update their knowledge on the growing body of evidence regarding the advancements of these technologies to reduce potential complications and select the most cost-effective treatment options for each patient.

Conclusion: Try to understanding the underlying biophysical principles and more in-depth familiarity with various electrosurgical devices could lead to less complications and optimize evidence-based gynecological practice.

Complications of Hysteroscopic and Uterine Resectoscopic Surgery

Adverse events associated with hysteroscopic procedures are generally rare, but, with increasing operative complexity, it is now apparent that they are experienced more often. There exists a spectrum of complications that relate to generic components of procedures, such as patient positioning, anesthesia, and analgesia, to a number that are specific to intraluminal endoscopic surgery that largely comprise perforation and injuries to surrounding structures and blood vessels. Whereas a number of endoscopic procedures require the use of distending media, the response of premenopausal women to excessive absorption of nonionic fluids used for hysteroscopy is somewhat unique, and deserves special attention on the part the surgeon. There is also an increasing awareness of uncommon but problematic sequelae related to the use of monopolar radiofrequency uterine resectoscopes that involve thermal injury to the vulva and vagina. Furthermore, the uterus that has previously undergone hysteroscopic surgery may behave in unusual ways, at least in premenopausal women who experience menstruation or who become pregnant. Fortunately, better understanding of the mechanisms involved in these adverse events, as well as the use or development of a number of innovative devices, have collectively provided the opportunity to perform hysteroscopic and resectoscopic surgery in a manner that minimizes risk to the patient.

Implementing AORN recommended practices for MIS: Part II

This article focuses on the equipment and workplace safety aspects of the revised AORN "Recommended practices for minimally invasive surgery." A multidisciplinary team that includes the perioperative nurse should be established to discuss aspects of the development and design of new construction or renovation (eg, room access, ergonomics, low-lighting, OR integration, hybrid OR considerations, design development). Equipment safety considerations during minimally invasive surgical procedures include using active electrode monitoring; verifying the properties of distention media; using smoke evacuation systems; reducing equipment, electrical, thermal, and fire hazards; performing routine safety checks on insufflation accessories; and minimizing the risk of ergonomic injuries to staff members. Additional considerations include using video recording devices, nonmagnetic equipment during magnetic resonance imaging, and fluid containment methods for fluid management.

AAGL practice report: practice guidelines for the diagnosis and management of submucous leiomyomas

Submucous leiomyomas or myomas are commonly encountered by gynecologists and specialists in reproductive endocrinology and infertility with patients presenting with 1 or a combination of symptoms that include heavy menstrual bleeding, infertility, and recurrent pregnancy loss. There exists a variety of interventions that include those performed under hysteroscopic, laparoscopic and laparotomic direction; an evolving spectrum of image guided procedures, and an expanding number of pharmaceutical agents, each of which has value for the appropriately selected and counseled patient. Identification of the ideal approach requires the clinician to be intimately familiar with a given patient's history, including her desires with respect to fertility, as well as an appropriately detailed evaluation of the uterus with any one or a combination of a number of imaging techniques, including hysteroscopy. This guideline has been developed following a systematic review of the evidence, to provide guidance to the clinician caring for such patients, and to assist the clinical investigator in determining potential areas of research. Where high level evidence was lacking, but where a majority of opinion or consensus could be reached, the guideline development committee provided consensus recommendations as well.
