Single-Center Experience with Magnetic Retraction in Colorectal Surgery.
Appropriate tissue retraction is essential in laparoscopic surgery, and colorectal operations often require an additional incision and trocar that can disturb visualization and maneuverability. Each incision carries an increased risk for complications as well as increased pain and cosmetic issues. Magnetic devices have been developed for a less invasive retraction. The objective of this study is to report our initial experience using magnet retraction.
Ten consecutive patients who underwent laparoscopic colorectal procedures by a single surgeon using a magnetic retractor (Levita Magnetics® Surgical System, San Mateo, CA) between October 2017 and June 2018 at Duke Regional Hospital in Durham, NC, were included.
The cases included four single-port right colectomies, one sigmoidectomy, and five rectopexies. Nine cases were completed laparoscopically, as one right colectomy required conversion due to adhesions and bulky specimen. Indications included adenocarcinoma, diverticular disease, and rectal prolapse. The magnet was successfully used for uterus, colon, or colonic pedicle retraction. No intraoperative or 30-day complications were observed.
Magnetic surgical retractors are a safe, dynamic, and incision-less option for surgical field exposure during laparoscopic colorectal surgery. Reduced trocars decrease tissue trauma, enhances maneuverability, and potentially improves outcomes; however, further studies are required.
