Insights
Longer postoperative drainage (3-6 days) for chronic subdural hematoma (CSDH) after burr-hole surgery may reduce recurrence. However, the impact on mortality requires further investigation, guiding future clinical practice for CSDH management.
Area of Science:
- Neurosurgery
- Clinical Outcomes Research
Background:
- Chronic subdural hematoma (CSDH) presents a significant neurosurgical challenge.
- High recurrence rates after burr-hole surgery necessitate optimized treatment protocols.
- The ideal postoperative drainage duration for CSDH remains a subject of clinical debate.
Purpose of the Study:
- To conduct a systematic review and network meta-analysis.
- To determine the optimal postoperative drainage duration for CSDH.
- To minimize recurrence and improve clinical outcomes.
Main Methods:
- Systematic search of five databases up to January 2025.
- Inclusion of randomized controlled trials (RCTs) and cohort studies.
- Network meta-analysis of recurrence rates, mortality, and functional outcomes.
Main Results:
- Seven studies (1,842 patients) were analyzed.
- Drainage durations of 3 and 6 days significantly reduced CSDH recurrence compared to shorter durations.
- Six-day drainage showed the highest probability (86.2%) of minimizing recurrence; shorter durations (<24h) increased recurrence risk. No significant mortality differences were found.
Conclusions:
- Extended postoperative drainage (3-6 days) appears beneficial for reducing CSDH recurrence after burr-hole surgery.
- The effect of drainage duration on mortality requires further clarification.
- Optimizing drainage duration is crucial for CSDH management, warranting further high-quality research.
Background:
Chronic subdural hematoma (CSDH) is a prevalent neurosurgical condition with a high recurrence rate after burr-hole surgery. The optimal duration of postoperative drainage remains controversial, with varying clinical practices worldwide.
Objective:
This systematic review and network meta-analysis aimed to determine the optimal postoperative drainage duration to minimize recurrence while maintaining favorable clinical outcomes.
Methods:
A comprehensive search was conducted across five databases up to January 2025, including randomized controlled trials (RCTs) and cohort studies evaluating the postoperative drainage duration in CSDH patients undergoing burr-hole surgery. The primary outcome was recurrence rate, while the secondary outcomes included mortality and functional outcomes. A random-effects network meta-analysis was performed, and the risk of bias was assessed using standardized tools.
Results:
Seven studies with 1,842 patients were included, comprising three RCTs and four cohort studies. Drainage durations of 3 and 6 days significantly reduced recurrence rates compared with shorter durations (0-8 h and 17-24 h). Notably, the 6-day drainage had the highest probability (86.2%) of minimizing recurrence, followed by the 3-day drainage (13.8%). A shorter drainage duration (< 24 h) was associated with higher recurrence risks. However, no significant differences in mortality rates were observed across the drainage durations.
Conclusion:
This study highlights that longer postoperative drainage durations (3-6 days) may reduce recurrence rates after burr-hole surgery for chronic subdural hematomas. However, its effect on mortality remains unclear. These findings support the importance of optimizing the drainage duration and call for further high-quality studies to guide clinical practice.
