Anterior retroperitoneal lumbosacral spine exposure: operative technique and results.

We review our two-team operative technique and results of anterior retroperitoneal lumbosacral spine exposure for diskectomy, partial corpectomy, and spinal instrumentation. Seventy-two patients with lumbar spondylosis and associated symptomatic radiculopathy had this exposure between January 1, 2000 and January 1, 2002. A single disc space was isolated in 54 patients. Multilevel exposure was achieved in 18 patients. Main outcome measures included intra- and postoperative complications, blood transfusion requirements, duration of ileus, incidence of erectile/sexual dysfunction, and length of hospital stay. A single small bowel enterotomy and iliac vein laceration, both repaired primarily, were the only intraoperative complications. Perioperative blood transfusions were required in 13 patients (18%). Mean length of postoperative ileus was 3.5 days and average length of hospital stay was 5 days. Postoperative complications occurred in 7 patients (9.7%). These included erectile dysfunction (2), transient unilateral lower extremity paresis (1), acute acalculous cholecystitis (1), femoral vein thrombosis (1), pneumonia (1), and acute myocardial infarction (1). There were no genitourinary or other major vascular injuries. A two-team approach for lumbosacral spine instrumentation via anterior retroperitoneal exposure capitalizes on unique specialty-specific surgical skills. This paradigm facilitates safe lumbosacral spine surgery and major perioperative complications are rare.
