[Endoscopic neurosurgery combined with intraventricular lavage for pyogenic ventriculitis]

Objective: To investigate the efficacy of endoscopic neurosurgery combined with intraventricular lavage for pyogenic ventriculitis. Methods: A retrospective analysis of 45 patients with pyogenic ventriculitis in six hospitals which included Beijing Shijitan Hospital and Peking Union Medical College Hospital from 2001 to 2017. Twenty-four patients (non-endoscopic group) were treated with external ventricular drainage combined with intraventricular antibiotics administration from 2001 to 2009. Twenty-one patients (endoscopic group) was treated by endoscopic neurosurgery combined with intraventricular antibiotics lavage from 2010 to 2017. The drainage time, mortality, and modified Rankin score (mRS) after 6 months of follow-up were compared between the two groups. Results: Drainage time: (20±6) days in the endoscopic group, and (42±10) days in the non-endoscopic group. There was a significant difference between the two groups (P<0.001). Days in hospital: (29±7) days in the endoscopic group, and (51±11) days in the non-endoscopic group. There were significant differences between the two groups (P<0.001). Mortality: 8 patients (33.3%) died in the non-endoscopy group, and 1 patient (4.76%) died in the endoscopy group. There was a significant difference between the two groups (P=0.017). After 6 months of follow-up, patients of mRS≤3 were 14 cases (66.67%) in the endoscopy group, and 7 cases (29.17%) in the non-endoscopic group. There was a significant difference between the two groups (P=0.001). Conclusion: Endoscopic neurosurgery combined with intraventricular antibiotics saline lavage for pyogenic ventriculitis is an effective assessment and treatment method, and it is worth further promotion and application.
