However, seeking for better outcomes for patients and avoiding extensive bony loss with its sequences had raised minimally invasive technique for treating these disorders as an alternative surgery. Methods: This is a retrospective study in which 54 patients of LCS were operated upon via unilateral minimally invasive technique to decompress the canal in a 360 degrees fashion through laminotomy, deroofing of opposite laminar side, sublaminar ligamintectomy, bilateral foraminotomies and discectomy. We used VAS scores and ODI to assess clinical outcomes with a period of one year follow-up. Results: Our results demonstrated that minimally invasive techniques for treating these disorders are effective procedures. Minimally invasive 360 degrees decompression for treating LCS had better outcomes regarding postoperative back pain, smaller incisions, less bony loss and early ambulation. Conclusion: Minimally invasive techniques for treating lumbar canal stenosis of different causes could be considered a better option instead of traditional full laminectomy with better outcomes as regards respecting the anatomical layers such as posterior spinal integrity and musculature, postoperative pain, accompanied with less blood loss, shorter hospital stays, and shorter recovery periods.展开更多

Surgical management of lumbar degenerative disease has historically been approached by way of open surgical procedures aimed at decompressing and/or stabilizing the lumbar spine. Advances in technology andsurgical instrumentation have led to minimally invasive surgical techniques being developed and increasingly used in the treatment of lumbar degenerative disease. Compared to the traditional open spine surgery, minimally invasive techniques require smaller incisions and decrease approach-related morbidity by avoiding muscle crush injury by self-retaining retractors, preventing the disruption of tendon attachment sites of important muscles at the spinous processes, using known anatomic neurovascular and muscle planes, and minimizing collateral soft-tissue injury by limiting the width of the surgical corridor. The theoretical benefits of minimally invasive surgery over traditional open surgery include reduced blood loss, decreased postoperative pain and narcotics use, shorter hospital length of stay, faster recover and quicker return to work and normal activity. This paper describes the different minimally invasive techniques that are currently available for the treatment of degenerative disease of the lumbar spine.展开更多

The purpose of the present study was to investigate whether minimally invasive puncture and drainage(MIPD) could provide improved patient outcome compared with decompressive craniectomy(DC).Methods: Eligible, consecutive patients with ICH(≥30 ml, in basal ganglia, within 24 hours of ictus) were nonrandomly assigned to receive MIPD(group A) or to undergo DC(group B) hematoma evacuation. The primary outcome was death at 30 days after onset. Functional independence was assessed at 1 year using the Glasgow Outcome Scale(GOS, scores range from 1 to 5, score 1 indicating death, ≥4 indicating functional independence, with lower scores indicating greater disability). Results: A total of 198 patients met the per protocol analysis(84 cases in group A and 114 cases in group B), including 9 cases lost during follow-up(2 cases in group A and 7 cases in group B). For these 9 patients, their last observed data were used as their final results for intention-to-treat analysis. The mean age of all patients was 57.1 years(range of 31-95 years), and 114 patients were male. The initial Glasgow Coma Scale(GCS) score was 8.1±3.4, and the National Institutes of Health Stroke Scale(NIHSS) score was 20.8±5.3. The mean hematoma volume(HV) was 56.7±23.0 ml(range of 30-144 ml), and there was extended intraventricular hemorrhage(IVH) in 134 patients(67.7%). There were no significant intergroup differences in the above baseline data, except group A had a higher mean age(59.4±14.5years) than the mean age of group B(55.3±11.1 years, P=0.025). The total cumulative mortalities at 30 days and 1 year were 32.3% and 43.4%, respectively, and there were no significant differences between groups A and B(30 days: 27.4% vs. 36.0%, P=0.203; 1 year: 36.1% vs. 48.2%, P=0.112, respectively). However, the mortality for patients ≤60 years, NIHSS【15 or HV≤60 ml was significantly lower in group A than that in group B(all P【0.05). The total cumulative functional independence at 1 year was 26.8%, and the difference between group A(33/43, 39.3%) and group B(20/144, 17.5%) was significant(absolute difference 21.7%, odds ratio [OR] 0.329, 95% confidence interval [CI] 0.171 to 0.631, P=0.001). For patient with severe IVH, the 30 days and 1 year mortality rates were significant lower in group B than those in group A(P=0.025, P=0.036). However, the number of favorable outcomes had no significant difference between groups at 1 year post ictus. Multivariate logistic regression analysis showed that a favorable outcome after 1 year was associated with the difference in therapies(OR 0.280, 95% CI 0.104–0.752, P=0.012), age(OR 0.215, 95% CI 0.069–0.671, P=0.008), GCS(OR 1.187, 95% CI 1.010–1.395, P=0.037), HV(OR 0.943, 95% CI 0.906–0.982, P=0.005), IVH(OR 0.655, 95% CI 0.506–0.849, P=0.001) and PI(OR 0.211, 95% CI 0.071–0.624, P=0.001). Conclusions: Our results suggest that for patients with hypertensive spontaneous ICH(HV≥30 ml in basal ganglia), MIPD may be a more effective treatment than DC, as assessed by a higher rate of functional independence at 1 year after onset as well as reduced mortality in patients ≤60 years of age, NIHSS【15 or HV≤60 ml. For patients with HV 】60 ml, deep coma and severe IVH, the outcomes of the two therapies were similar.展开更多

We discuss our results, comparing this procedure (from a technical point of view) with the muscle-preserving interlaminar decompression (MILD) and the unilateral approach for bilateral decompression (ULBD). Clinical and outcome data of 62 consecutive patients were reviewed, using the Visual Analogue Scale for both low back pain (LBP) and legs pain and the Oswestry Disability Index (ODI) for the degree of disability. Mean age was 68.88 ± 9.54 years and mean follow-up (FU) was 16.38 ± 11.12 months. A statistically significant improvement of LBP, legs pain and ODI was globally observed. At latest FU, patients with multilevel lumbar spinal stenosis significantly improved all scores and patients with spondylolisthesis significantly decreased their disability. No major complications occurred. Two cerebrospinal fluid (CSF) collections were treated conservatively. No wound infection occurred. No progression of spondylolisthesis was observed. No reoperation was needed. Although efficacious in patients with lumbar spinal stenosis, MILD and ULBD can have both some limitations. MILD has been found to decrease lumbar function in multilevel decompression (increasing sagittal translation and lumbar lordosis probably due to the removal of half of the spinous processes) and ULBD shows some disadvantages due to the difficulty of manipulating instruments through a small portal and the inadequate decompression due to a minimal exposure. The minimal invasive bilateral interlaminar decompression (in this technique, the access is bilateral but the supraspinous and interspinous ligaments and the spinous processes are preserved) allows wide access (bilateral exposure) with minimal invasiveness and very low morbidity in patients with lumbar spinal stenosis at one or more levels.展开更多

文摘目的：比较微创通道下单侧椎板开窗减压术与开放减压内固定术治疗腰椎管狭窄症的疗效.方法：对2008年3月至2011年2月手术治疗的82例腰椎管狭窄症患者进行回顾性分析.根据手术方式不同分为A、B两组,A组32例,采用微创通道下单侧椎板开窗椎管减压术治疗,男13例,女19例;平均年龄（56.31±4.31）岁;减压1个节段23例,2个节段9例.B组50例,采用开放减压内固定术治疗,男18例,女32例;平均年龄（57.53±4.28）岁;减压1个节段38例,2个节段12例.术前术后均采用视觉分析量表（visual analog scale,VAS）和Oswestry功能残损量表（Oswestry disability index,ODI）,评估腰痛、腿痛和行走耐受性（行走距离和耐受程度）.结果：82例均获随访,平均随访时间32.8个月（10.9～43.4个月）,两组患者在年龄、狭窄节段、术前腰腿痛VAS和ODI方面差异无统计学意义,但A组手术时间比B组短,出血量、住院时间、恢复日常生活时间和住院费用等方面比B组少.并发症方面两组间差异无统计学意义.结论：微创单侧椎板开窗减压术是治疗退变性腰椎管狭窄症的微创、有效的手术方式,可以在保留后方稳定结构的前提下使神经结构得到充分减压,在手术时间、出血量、住院时间、恢复日常生活时间和住院费用等方面有明显优势,可在把握严格手术适应证的前提下作为治疗退变性腰椎管狭窄症特别是老年患者的主要手术方法.
