Abstract

We describe the technique we routinely use to perform the retroperitoneal anterior approach using a rigid endoscope coupled to a HDD screen to assist mini-open retroperitoneal anterior approach. Our experience was compared to those reported in the literature for the standard mini-open retroperitoneal approach. We retrospectively analyzed a total of 269 consecutive patients, 109 males and 160 females, underwent anterior lumbar approach in our department, using video-assisted anterior retroperitoneal approach to the lumbar spine. 202 patients had a single L5-S1 or L4-5 ALIF (75.09%), 14 patients received a double level ALIF (5.3%), while 53 patients underwent a double anterior and posterior approach (19.8%). The average preoperative VAS and Oswestry Disability Index (ODI) scores were 9.1±6.3 and 79.3±11.9. At least 16 months follow-up (from 16 months to 5 years), the average VAS and ODI values had improved to 1.6±1.5 and 13.1±13.2, respectively (p <0.05). The mean length of stay was 4.3±3.5 days. There were 6 major complications (2.2%) related to the approach: major vascular injuries (iliac vein injury) occurred in a total of 3 patients (1.1% of cases), whereas retrograde ejaculation occurred in 3 patients (2,75% of male cases in the series). No wound or deep infections occurred. In our opinion, this technique, compared with other mini-open approach, potentially reduces perioperative morbidity, length of surgery, surgical approach-related complications, and hospitalization.
