Da Vinci Robotic Assistance for Anterolateral Lumbar Arthrodesis: Results of a French Multicentric Study.

BACKGROUND

The da Vinci robot (DVR) is the most widely used robot in abdominal, urological, and gynecological surgery. Due to its minimally invasive approach, the DVR has demonstrated its effectiveness and improved safety in these different disciplines. The aim of our study was to report its use in an anterior approach of complex lumbar surgery.

METHODS

In a retrospective multicenter observational study, 10 robotic-assisted procedures were performed from March 2021 to May 2022. Six oblique lumbar interbody fusion procedures and 4 lumbar corpectomies were performed by anterolateral approach assisted by the DVR. The characteristics of the patients and the intraoperative and postoperative data were recorded.

RESULTS

Six men and 4 women underwent surgery (mean age 50.5 years; body mass index 28.6 kg/m2). No vascular injuries were reported, and no procedures required conversion to open surgery. Mean surgical time were 219 minutes for 1-level oblique lumbar interbody fusion (3 patients), 286 minutes for 2-level oblique lumbar interbody fusion (3 patients), and 390 minutes for corpectomy (4 patients). Four patients experienced nonserious adverse events due to lumbar plexus nerve damage. One patient had a vertebral body plate fracture requiring posterior revision surgery, and 1 patient had a psoas hematoma requiring transfusion. No abdominal wall complications or surgical site infection were found. Seven patients were reviewed at 12 months, none had complications, and all showed radiological evidence of fusion.

CONCLUSIONS

The use of the DVR in lumbar surgery allows a safe minimally invasive transperitoneal approach, but to date, only hybrid procedures have been performed.
