Abstract: Objective To observe the influencing factors of cerebrospinal fluid leakage after endoscopic transsphenoidal pituitary adenoma resection,and promote the early identification of high-risk patients with this complication. Methods Retrospective analysis was made on the clinical data of 176 patients with pituitary adenoma who underwent endoscopic transsphenoidal pituitary adenoma resection in Department of Neurosurgery,Second Affiliated Hospital of Nanjing Medical University from May 2019 to October 2022,and the cerebrospinal fluid leakage after operation was counted.Single factor analysis was used to screen the possible influencing factors of postoperative cerebrospinal fluid leakage,and logistic regression analysis was used to determine the independent risk factors. Results 12 of 176 patients with pituitary adenoma had cerebrospinal fluid leakage after operation,the incidence was 6.82% (12/176).Univariate analysis showed that tumor diameter,reoperation,intraoperative cerebrospinal fluid leakage,and intraoperative cerebrospinal fluid leakage classification were related to postoperative cerebrospinal fluid leakage (P<0.05).Logistic regression analysis showed that tumor diameter (OR=3.843,95%CI=1.652~8.940),reoperation (OR=2.407,95%CI=1.094~5.298),intraoperative cerebrospinal fluid leakage (OR=4.552,95%CI=1.483~13.972),and intraoperative cerebrospinal fluid leakage classification (OR=3.516,95%CI=1.204~10.269) were independent risk factors for postoperative cerebrospinal fluid leakage (P<0.05). Conclusion Tumor diameter,reoperation,intraoperative cerebrospinal fluid leakage,and intraoperative cerebrospinal fluid leakage classification are closely related to cerebrospinal fluid leakage after endoscopic transsphenoidal pituitary adenoma resection,we should pay close attention to the strategies of sellar floor reconstruction in the above patients,and strengthen the observation of the signs of cerebrospinal fluid leakage after surgery.
