Efficacy of neuroendoscopy-assisted surgery in the treatment of chronic subdural hematoma: a meta-analysis.

Background: Chronic subdural hematoma (CSDH) is one of the most common diseases in neurosurgery. It is the result of chronic intracranial hemorrhage that converges between the dura mater and arachnoid three weeks after externally injuring the head. Chronic subdural hematomas are a common complication in neurosurgery. With the gradual increase in the amount of hematoma, the surrounding brain tissue is pushed and compressed, resulting in corresponding clinical symptoms and signs. It is reported that the overall incidence rate of CSDH is 1.72 to 20.6 per 100,000 people every year, and the incidence rate of the elderly is particularly high.

Methods: The computer retrieves eight databases to obtain controlled trials at home and abroad on the effects of neuroendoscopy-assisted surgery in patients with chronic subdural hematoma. After a rigorous literature quality evaluation, data analysis was performed using RevMan 5.3 software.

Results: Twenty studies were ultimately included in this meta-analysis. Seventeen studies reported the Recurrence rate of the test group and the control group, which was significantly lower (OR 0.27; 95% Cl 0.18, 0.38; P < 0.01) than the control group, Recovery rate (OR 1.18; 95% Cl 1.01, 1.38; P = 0.03), Total effective rate (OR 1.11; 95% Cl 1.04, 1.17; P < 0.01), Operative time (SMD 15.78; 95% Cl 9.69, 21.86; P < 0.01), Hospital stay (SMD - 1.66; 95% Cl - 2.17, - 1.14; P < 0.01) and Complications (OR 0.48; 95% Cl 0.30, 0.78; P < 0.01).

Conclusion: The results of this study suggest that neuroendoscopy-assisted surgery may be effective in patients with chronic subdural hematoma, as evidenced by recurrence rate, recovery rate, total effective rate, operative time, hospital stay, complications, and the above conclusions need to be verified by more high-quality studies.
