The authors studied 122 patients who had undergone microsurgery for herniated lumbar disc or isolated nerve root canal stenosis. The patients were reviewed one month and three months after surgery and then returned for a final evaluation after an average of 1.4 years. Intraoperative or postoperative complications occurred in 13 cases and consisted of misdiagnosis (discovered intraoperatively) of the level of the herniated disc (7 cases), dural laceration (3 cases), and discitis (3 cases). Limited discectomy was performed in 16 cases and complete discectomy in the others. Two patients who had undergone limited discectomy experienced recurrence; this did not occur when complete discectomy was performed. Discitis occurred in patients who had undergone complete discectomy. Most of the patients who underwent operation for disc herniation at one lumbar level with no complications began walking within 24 hours, and 72% were discharged within 36 hours. Eighty-five percent of the patients had a satisfactory result one month after surgery, and 91% had a satisfactory result at the final follow-up. There was no significant difference between patients with protruded herniation and patients with sequestered herniation. In the patients with nerve root canal stenosis the proportion of satisfactory results was 72% at one month and 88% at the final follow-up. The main advantage of microsurgery is the full illumination of the operative field, and this technique is strongly indicated in cases of single-level herniated disc. Over the short-term, microdiscectomy achieves a higher proportion of satisfactory results, requires a shorter hospitalization period, and allows an earlier return to work than traditional surgery. However, no significant difference was found between microsurgery and traditional surgery over the long-term.

Abstract
The authors studied 122 patients who had undergone microsurgery for herniated lumbar disc or isolated nerve root canal stenosis. The patients were reviewed one month and three months after surgery and then returned for a final evaluation after an average of 1.4 years. Intraoperative or postoperative complications occurred in 13 cases and consisted of misdiagnosis (discovered intraoperatively) of the level of the herniated disc (7 cases), dural laceration (3 cases), and discitis (3 cases). Limited discectomy was performed in 16 cases and complete discectomy in the others. Two patients who had undergone limited discectomy experienced recurrence; this did not occur when complete discectomy was performed. Discitis occurred in patients who had undergone complete discectomy. Most of the patients who underwent operation for disc herniation at one lumbar level with no complications began walking within 24 hours, and 72% were discharged within 36 hours. Eighty-five percent of the patients had a satisfactory result one month after surgery, and 91% had a satisfactory result at the final follow-up. There was no significant difference between patients with protruded herniation and patients with sequestered herniation. In the patients with nerve root canal stenosis the proportion of satisfactory results was 72% at one month and 88% at the final follow-up. The main advantage of microsurgery is the full illumination of the operative field, and this technique is strongly indicated in cases of single-level herniated disc. Over the short-term, microdiscectomy achieves a higher proportion of satisfactory results, requires a shorter hospitalization period, and allows an earlier return to work than traditional surgery. However, no significant difference was found between microsurgery and traditional surgery over the long-term.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
