N2 - Background: The optimal management of symptomatic lumbar disc herniations (LDH) remains controversial. This study examines the feasibility and safety of a video-assisted endoscopic intracanalicular technique for managing symptomatic LDH. Methods: From September 1999 to June 2000, we used the current technique, the Vertebroscope System, on 11 patients (six men, five women), aged from 18 to 61 years (mean, 45), who had suffered symptomatic LDH. The disc levels involved were at L4-L5 (n=8), and L5-S1 (n=3). The Vertebroscope, which has a 30° viewing angle and a working channel 1.7 cm in diameter, was used for the minimally invasive endoscopic procedures. The mean follow-up period was 12 months (range, 6-15). Results: The operating time ranged from 60 to 335 min (mean, 136.5), and the estimated blood loss during operation was minimal to 200 ml. The mean length of the paramedian skin incisions was 2 cm. No drainage tube was used postoperatively. The mean hospital stay was 3 days (range, 2-5), with five patients discharged on the 1st postoperative day. Complications included one superficial wound infection, one conversion to an open procedure when muscle herniation into the working channel created a technical difficulty in approaching the ligamatum flavum, and one minor tear of the nerve root sleeve that did not require further surgery. In the first five patients studied herein, the mean operating time was significantly longer than that for the later five patients (201 vs 72 min, p<0.001). Conclusions: The advantages of the current endoscopic disectomy technique include its minimally invasive character, with less paraspinal muscle trauma, direct address to the lesion site that resembles the open technique, and enhanced operative field visualization with a paramedian skin incision of just 2 cm. Practice is needed to perfect such an endoscopic approach for lumbar disc excision, so the operating time decreased significantly as the surgeons became more familiar with this endoscopic technique. It has proved to be safe and effective for treating patients with symptomatic LDH.
