Abstract
Introduction:
Tissue retraction during minimally invasive surgery has been achieved to date with patient positioning or additional instrumentation. The Levita™ Magnetic Surgical System (San Mateo, CA), a novel, noninvasive, magnetic retraction device for minimally invasive surgery, has been used to facilitate reduced-port robotic prostatectomy using a multiport robotic platform. With the release of the da Vinci SP robotic system (Intuitive, Sunnyvale, CA), we now report a multi-institutional initial case series of magnet-assisted robotic prostatectomy using the single-port robotic platform.
Materials and Methods:
An IRB-approved, retrospective chart review was performed of all patients undergoing robot-assisted radical prostatectomy using the da Vinci SP surgical system and a single Levita magnetic retractor in treatment of prostatic adenocarcinoma at two institutions from November 2018 to January 2019. Preoperative, intraoperative, and postoperative data were collected for descriptive analysis.
Results:
A total of 15 men, median age 62 years (range 57–71), with mean PSA 7.0 ± 2.3 underwent surgery. The robotic cannula and a single 12-mm assistant port were utilized in all cases, the latter for suction, suture passage, and clip placement; the magnetic retractor aided with posterior dissection, dorsal venous complex stitch placement, bladder neck dissection, and lymphadenectomy. No cases required conversion to a multiport robotic platform, laparoscopy, or open surgery, nor placement of additional assistant ports. No intraoperative or postoperative complications occurred. Average operative time was 224 ± 43 minutes and blood loss was 198 ± 115 mL. All patients were discharged home within 2 days of surgery.
Conclusions:
Robotic prostatectomy utilizing the da Vinci SP system is feasible, safe, and effective. Use of the magnetic retractor facilitates tissue exposure and improves procedure ergonomics, mimicking the conventional multiport technique. Further exploration of magnet utilization in robotic surgery and optimization of assistant port placement for true single-site surgery is warranted.
