Abstract

Objective: To investigate the effectiveness of one-hole split endoscope (OSE) technique in the treatment of single segment lumbar spinal stenosis (LSS).

Methods: The clinical data of 32 single segment LSS patients treated with OSE technique for simple spinal canal decompression between January 2022 and December 2022, who met the selection criteria, were retrospectively analysed. There were 18 males and 14 females, the age ranged from 45 to 82 years, with an average of 65.1 years. The disease duration was 9-72 months, with an average of 34.9 months. The surgical segments included L 3, 4 in 3 cases, L 4, 5 in 19 cases, and L 5S 1 in 10 cases. The incision length, operation time, intraoperative blood loss, intraoperative radiation exposure frequency, postoperative mobilization time, and the area of the patient’s lesion segment dural sac before operation and at 1 month after operation were recorded. Low back pain and leg pain were assessed by visual analogue scale (VAS) score before operation and at 3 days, 3 months, and 12 months after operation; functional recovery was assessed by Oswestry disability index (ODI) before operation and at 3 months and 12 months after operation; the effectiveness was assessed by modified MacNab criteria at last follow-up.

Results: All 32 patients successfully completed the operation, with an average incision length of 2.05 cm, an average operation time of 88.59 minutes, an average intraoperative blood loss of 46.72 mL, an average intraoperative radiation exposure frequency of 3.84 times, and an average postoperative mobilization time of 11.66 hours. All patients were followed up 12-16 months, with an average of 13.5 months. One patient experienced lower limb numbness, pain, and decreased muscle strength after operation, while the remaining patients did not experience complications such as dural tear or important nerve damage. The VAS scores of low back pain and leg pain and ODI in patients at various time points after operation were significantly better than preoperative ones, and each indicator further improved with time. The differences between time points were significant ( P<0.05). At 1 month after operation, the area of the patient's lesion segment dural sac was (123.13±19.66) mm 2which significantly increased compared to preoperative (51.25±9.50) mm 2 ( t=-18.616, P<0.001). At last follow-up, the improved MacNab criteria were used to evaluate the effectiveness, with 18 cases achieving excellent results, 11 cases being good, and 3 cases being fair, with an excellent and good rate of 90.6%.

The effectiveness of using OSE technique for simple spinal canal decompression treatment of single segment LSS is satisfactory, with the advantages of minimal surgical trauma and fast recovery.

Purpose: To explore the clinical efficacy of one-hole split endoscopy (OSE) technology in the treatment of single-level lumbar spinal stenosis (LSS). .

method: The clinical data of 32 single-level LSS patients who were treated with simple spinal canal decompression using OSE technology from January to December 2022 and met the selection criteria were retrospectively analyzed. There were 18 male cases and 14 female cases; the age range was 45 to 82 years old, with an average age of 65.1 years. The duration of disease ranged from 9 to 72 months, with an average of 34.9 months. Surgery level: L 3、4 3 cases, L 4、5 19 cases, L 5、S 1 10 cases. The incision length, operation time, intraoperative blood loss, intraoperative radiation exposure times, postoperative out-of-bed activity time, and the patient’s diseased segment dural sac area before operation and 1 month after operation were recorded. The visual analogue scale (VAS) for pain in the waist and legs was evaluated before surgery and 3 days, 3 and 12 months after surgery; the Oswestry Disability Index (ODI) was used to evaluate functional recovery before surgery and 3 and 12 months after surgery. situation; the modified MacNab criteria were used to evaluate the efficacy at the last follow-up. .

result: All 32 patients successfully completed the operation, with an average incision length of 2.05 cm, an average operation time of 88.59 minutes, an average intraoperative blood loss of 46.72 mL, an average of 3.84 intraoperative radiation exposures, and an average postoperative ambulation time of 11.66 hours. All patients were followed up for 12 to 16 months, with an average of 13.5 months. One patient developed numbness, pain, and decreased muscle strength in the lower limbs after surgery, while the remaining patients did not suffer complications such as dural tear or important nerve damage. The VAS scores and ODI of patients’ waist and leg pain at each time point after surgery were significantly better than those before surgery, and each index further improved over time, and the differences between each time point were statistically significant ( P<0.05)。术后1个月患者病变节段硬膜囊面积为(123.13±19.66)mm 2compared with preoperative (51.25±9.50) mm 2significantly increased ( t=−18.616, P<0.001)。末次随访时,采用改良MacNab标准评估疗效,获优18例、良11例、可3例,优良率90.6%。.

in The clinical efficacy of simple spinal decompression using OSE technology to treat single-level LSS is satisfactory, with the advantages of less surgical trauma and faster recovery. .
