Abstract

Objective Postoperative cerebrospinal fluid (CSF) leakage in endoscopic transsphenoidal surgery is a potential risk that requires immediate repair. We investigated the potential of common postoperative hematological examinations for diagnosing postoperative CSF leakage.

Methods We retrospectively studied 214 consecutive cases who underwent endoscopic transsphenoidal approach (ETSA; transsellar approach) or extended ETSA (E-ETSA). Patients with postoperative CSF leakage were defined the leak group (group L), and patients without were defined as the nonleak group (group N). Postoperative C-reactive protein (CRP) was compared between the ETSA and E-ETSA groups, and between the N and L groups.

Results The values of white blood cell count and CRP 1 to 7 days after surgery were significantly higher in the L group. Especially, CRP was clearly elevated in the L group (p < 0.001). The CRP value was higher in patients in the N group after E-ETSA than after ETSA (p < 0.001). CRP increased on the day after surgery but decreased gradually thereafter in patients after ETSA and in the N group. In contrast, CRP value tended to increase gradually after surgery in the L group. In particular, the CRP on the day before the CSF leak was confirmed was clearly higher than on the fifth to seventh days in the N group.

Conclusion Elevated CRP after endoscopic endonasal transsphenoidal surgery is a potential marker of CSF leakage.
