Application of Dural Suturing in Reconstruction of Sellar Floor for Cerebrospinal Fluid Leakage During Neuroendoscopic Intranasal Approach Surgery: A Meta-Analysis.

ABSTRACT

AIM: To assess the safety and efficacy of utilizing dural suturing as an adjunctive procedure for saddle floor reconstruction in patients undergoing endoscopic surgery in the sellar region. MATERIAL AND METHODS: According to the PRISMA guidelines, we searched the literature on sellar floor reconstruction in endoscopic sellar surgery. Fixed- or random-effects meta-analysis was used to pool the rate of return to postoperative cerebrospinal fluid (poCSF) leakage, repair operations, postoperative hospitalization, complete resection, infection, lumbar drainage (LD), and operative duration. RESULTS: A total of six studies involving 723 participants were included in the current meta-analysis. The pooled results demonstrated that patients in the dural suturing group had a lower incidence of poCSF leakage [odds ratio (OR), 0.18; 95% confidence interval (CI), 0.07 - 0.44; p=0.0002] and repair operation [OR, 0.24; 95% CI, 0.07 - 0.78; p=0.02], as well as a shorter hospitalization period [standardized mean difference (SMD), -0.45; 95% CI, -0.62 - -0.28; p < 0.00001]. There was no significant difference between the two groups in terms of the complete resection [OR, 1.06; 95% CI, 0.62 - 1.80; p=0.84], postoperative infection [OR, 0.49; 95% CI, 0.21 - 1.15; p=0.10] and lumbar drainage (LD) [OR, 0.28; 95% CI, 0.06 - 1.23; p=0.09]. Additionally, the dural suturing group may require a longer operative duration [SMD, 0.29; 95% CI, 0.02 - 0.56; p=0.03]. CONCLUSION: The results suggest that dural suturing can be advantageous in reducing postoperative complications and shortening postoperative hospitalization following neuroendoscopic surgery in the sellar region without increasing the risk of infection.
