[Mini-invasive extraperitoneal approach for anterior lumbar surgery]

Area of Science:

• Spine surgery
• Minimally invasive procedures
• Anterior lumbar approaches

Context:

• Anterior lumbar spine surgery traditionally involves significant muscle dissection and potential complications.
• Minimally invasive techniques aim to reduce surgical trauma and improve patient outcomes.
• The extraperitoneal approach offers an alternative route to the anterior lumbar spine.

Purpose:

• To evaluate the efficacy and safety of a mini-invasive extraperitoneal approach for anterior lumbar spine surgery.
• To detail the exposure technique, operative outcomes, and complications associated with this approach.
• To compare the benefits of this technique against traditional open anterior approaches.

Summary:

• Fifty-two patients underwent anterior lumbar surgery using a mini-invasive anterior extraperitoneal approach for various conditions including degenerative instability and discogenic pain.
• Key metrics recorded included operation time, blood loss, incision length, pain, and hospitalization duration.
• The approach provided clear exposure, with average operation time of 85 minutes, blood loss of 155 ml, and incision length of 6.5 cm. Postoperative recovery was rapid, with bed rest averaging 3 days and hospitalization 7-10 days.

Impact:

• The mini-invasive extraperitoneal approach provides excellent exposure of the anterior lumbar vertebrae and discs.
• This technique results in significantly less trauma, fewer complications, and reduced pain compared to traditional methods.
• The approach preserves the posterior spinal components, offering advantages for revision surgeries and overall spinal stability.
