Recent Advances in Laparoscopic Surgery for Gynecological Surgeons

Recent advances in laparoscopic surgery have revolutionized patient treatment for a variety of conditions. Compared to traditional surgery, a minimally invasive approach typically results in less pain and discomfort, quicker recovery times, and better patient outcomes. Early data suggests the evolution of laparoscopy may also benefit clinicians, yielding shorter operating times, clearer views of the surgical field and superior ergonomics during some procedures.

New Approaches

The continual drive for less invasive surgery has ignited growing interest in methods such as transvaginal natural orifice transluminal endoscopic surgery, observes Fertility and Sterility. Commonly referred to as vNOTES, the technique is an offshoot of natural orifice transluminal endoscopic surgery, where the mouth, urethra, rectum and other natural openings are used as access points for endoscopic surgery. In gynecologic surgery, vNOTES has been applied to the following procedures:

- Myomectomy

- Hysterectomy

- Salpingectomy

- Ovarian cystectomy

- Lymphadenectomy

- Sacrocolpopexy

Unlike traditional laparoscopic surgery, vNOTES calls for ports to be placed through a colpotomy incision, thus eliminating the need for incision in the abdomen. Instruments are then inserted through the vagina. The transvaginal route appears to minimize surgical complexity, permitting safe entry and simple closure. Evidence to date finds the technique may yield shorter surgical times and better ergonomics for surgeons performing the procedure, reports a 2020 systematic review in the Asian Journal of Surgery.

Yet, as with any innovation, vNOTES requires clinical education about the new entry point and surgical view. For example, the method requires clinicians to perform the technique while operating upside down: Their viewpoint looks superiorly up into the pelvis from the vagina rather than inferiorly from the umbilicus.

Advances in Instrumentation and Technology

As Current Women's Health Reviews reports, recent advances are also reshaping what tools are used in laparoscopic surgery. Minute mini-laparoscopy and percutaneous instruments, such as those smaller than 5 mm, may yield equivalent outcomes for certain operations while causing less abdominal wall trauma. Relatedly, narrow-band imaging may pick up more endometriosis lesions than past techniques. Even so, research finds that the clinical impact of the slight increase in sensitivity appears to be negligible over conventional white light laparoscopy.

On other fronts, robot-assisted surgery provides an alternative surgical avenue for minimally invasive gynecologic surgery, according to a 2020 joint committee opinion of the American College of Obstetricians and Gynecologists' (ACOG) Committee on Gynecologic Practice and the Society of Gynecologic Surgeons. Notably, the advent of high-definition 3D imaging technology in robotic-assisted surgery for endometriosis may offer a better view of the surgical field, thereby preventing sensory loss and improving depth perception, adds Fertility and Sterility. Moreover, small pilot studies have suggested surgeons may experience less shoulder, back and neck discomfort during robot-assisted surgery than with laparoscopy.

Similarly, the more widespread adoption of 3D imaging may provide welcome assistance to clinicians who are mastering the requisite skills for the laparoscopic environment, states Current Women's Health Reviews.

Toward Superior Patient Outcomes

Early data insights on vNOTES, thus far, find the technique to be just as good as laparoscopy for successful hysterectomy without conversion. A 2019 randomized control trial in BJOG reports less pain, shorter surgeries, fewer post-surgical complications and quicker hospital stays in vNOTES patients than in those undergoing laparoscopic hysterectomy.

A 2020 systematic review adds that vNOTES proves effective at removing ovarian cysts, large ectopic pregnancies and other sizable pathology — with the advantage of avoiding significant abdominal incisions. Relatedly, the use of a single trocar in vNOTES may reduce instrument-related injuries. However, the authors call for more research into comparative outcomes, safety, instruments and technique before widespread adoption of the method.

Although the quality of evidence on robotic-assisted gynecologic surgery remains low to moderate, a comparative study in the Journal of Robotic Surgery showed better detection of endometriosis lesions with a robot-assisted camera than a laparoscopic camera. Given the state of the data, ACOG encourages further comparative studies to evaluate long-term outcomes and patient safety. Such evidence would help identify specific subgroups of patients who stand to benefit from a robotic approach.

With an inrush of technological innovations and recent advances in laparoscopic surgery, clinicians may now offer more choices to patients who need intervention. Yet, as always, clinical decision-making about the use of one of these new approaches remains grounded in evidence-based medicine and the best interests of the patient.
