Background: Burr-hole irrigation surgery is now recognized as a widespread simple technique for the treatment of chronic subdural hematoma (CSDH). However, recurrence of CSDH is sometimes experienced after initial surgery. Recently, it has been reported that goreisan is effective in preventing CSDH recurrence. Materials and Methods: We studied patients with CSDH who received burr-hole irrigation at our hospital between January 2011 and December 2014. We divided these patients into three groups. The first group was given goreisan during the early phase after burr-hole irrigation. The second group was given goreisan when there was a visual tendency of recurrence, as observed in the course of computed tomography imaging for outpatients. The third group was not given any drug. Results: The recurrence rate was compared between each group. The recurrence rate was significantly lower in the early goreisan administration group (5% vs. 12%, P = 0.046). There was a decreased tendency of recurrence in the goreisan-administered group compared with the group that was not administered any drug, but this was not statistically different (6.1% vs. 12%, P = 0.082). The recurrence period in the goreisan-administered group was longer than that in the group that was not administered any drug (39.9 ± 12.1 vs. 27.45 ± 8.5, P = 0.017). Conclusions: Goreisan is effective in preventing recurrence of CSDH after burr-hole irrigation.
