Abstract
A surgical procedure includes forming an incision in a patient placed in the right lateral recumbent position to facilitate forming a retroperitoneal cavity. Dissection is formed with a balloon cannula, and the retroperitoneal cavity thus formed is then maintained by a mechanical lift or retractor positioned to elevate the wall of the cavity adjacent the patient's left side. The dissected peritoneum and the underlying bowel are displaced away from the spine by gravity with the patient thus positioned. An endoscope may be introduced into the retroperitoneal cavity to visualize surgery within the cavity including dissection of the iliopsoas muscle to facilitate discectomy and spinal fusion of adjacent vertebrae.
