AI Article Synopsis
- The study aimed to explore how bipolar electrocautery affects the development of epidural fibrosis after lumbar spine surgery in rats.
- Fourteen male rats were divided into two groups: one group underwent laminectomy with bipolar electrocautery, while the control group had laminectomy only.
- Results indicated that the group using bipolar electrocautery had significantly higher levels of TGF-β and collagen, suggesting increased epidural fibrosis compared to the control group, implying that reducing the use of bipolar cauterization may help lessen this issue.
Article Abstract
Aim: To investigate the role of bipolar electrocautery in the occurrence of epidural fibrosis following lumbar spine laminectomy in a rat model.
Material And Methods: Fourteen male Sprague-Dawley rats (age: 4-6 months, weight: 250-300 g) were randomly divided into two groups, a bipolar group (Group I) and a control group (Group II). Laminectomy was performed between the L1 and L3 levels. In Group I (n=7), a laminectomy was carried out and soft tissue around the spinal cord was coagulated by using a bipolar electrocautery. In the control group (n=7), only laminectomy was performed. The animals were sacrificed 4 weeks after surgery, and post-laminectomy epidural fibrosis (PLEF) was evaluated. Macropathological, qualitative and quantitative histological evaluations as well as immunohistochemical staining including transforming growth factor-β (TGF-β), collagen I and collagen III were performed.
Results: The numbers of TGF-β positive cells staining (PCS) were 3.00 ± 0.46 for Group I and 1.00 ± 0.52 for Group II. The numbers of collagen I PCS were 2.00 ± 0.93 for Group I and 1.25 ± 0.46 for Group II. The numbers of collagen III PCS were 2.25 ± 0.76 for Group I, 1.25 ± 0.46 for Group II, and TGF-β PCS than Group II (p≤0.05). Compared with the control group, Group I's formation of epidural fibrosis was significantly increased.
Conclusion: Our study clearly demonstrated that the use of bipolar cauterisation is associated with increased PLEF in the experimental animal model. Thus, limiting the use of bipolar cauterisation may be effective in reducing this complication.

Background: Post-laminectomy syndrome (PLS) manifests as recurrent chronic back pain, with or without radiating leg pain, affecting 10-40% of patients following laminectomy. While surgical interventions can alleviate recurrent disc herniation or joint instability, medical management of PLS remains challenging due to unsatisfactory outcomes. Epidural fibrosis is a frequent cause of PLS, leading to nerve root tethering and dural sac compression.

Postsurgical adhesions are a common complication associated with surgical procedures; they not only impact the patient's well-being but also impose a financial burden due to medical expenses required for reoperative surgeries or adhesiolysis. Adhesions can range from a filmy, fibrinous, or fibrous vascular band to a cohesive attachment, and they can form in diverse anatomical locations such as the peritoneum, pericardium, endometrium, tendons, synovium, and epidural and pleural spaces. Numerous strategies have been explored to minimize the occurrence of postsurgical adhesions.

Background: Fungal spondylitis often occurs in patients with immune dysfunction, and its diagnosis and treatment pose certain challenges. However, even in immunocompromised patients, Aspergillus spondylitis remains rare. This case reports the diagnostic and therapeutic experience of fungal spondylitis in a patient with consolidated cirrhosis and no significant immune impairment.
