Internal Grasper and Magnetic Anchoring Guidance System in Gynecologic Laparoendoscopic Single-site Surgery: A Case Series.

STUDY OBJECTIVE

To evaluate and report preliminary data after the use of an internal grasper and magnetic anchoring guidance system (MAGS) to allow free movement and optimal triangulation in the abdominal cavity during gynecologic laparoendoscopic single-site surgery (LESS).

DESIGN

A prospective, single-center case series.

SETTING

The First Affiliated Hospital of Xi'an Jiaotong University.

PATIENTS

Eighteen female patients underwent MAGS-assisted LESS with an internal grasper.

INTERVENTIONS

A single surgeon performed MAGS-assisted LESS on patients with benign gynecologic diseases while documenting operative time, device insertion time, surgeon assessment of technical adaptation, patient-evaluated pain and cosmetic outcomes, adverse events, and blood loss.

MEASUREMENTS AND MAIN RESULTS

Eighteen patients underwent transumbilical MAGS-assisted LESS using an internal grasper from November 1, 2019, to December 31, 2019. The mean operative time and insertion time were 98.7 minutes and 1 minute, respectively. The use of MAGS was easily mastered by the surgeon and considered consistently useful in overcoming the limitations of LESS. The patients reported average pain scores of 4.8, 2.3, and 0.5 immediately, 24 hours, and 1 week after surgery, respectively. All patients expressed satisfaction with the postoperative cosmetic results. No serious complications were observed. The mean blood loss was 43.6 mL.

CONCLUSION

MAGS-assisted LESS is easy to deploy and use for benign gynecologic disease and seems to result in positive outcomes. Larger randomized controlled trials are warranted.
