TABLE 3.

Complications for total patient cohort and each surgical group

Complication	Total (n = 276)	Procedure
		PFD (n = 69)	PFDwD + PFDwDO (n = 207)	p Value
Any complication	9 (3.3)	2 (2.9)	7 (3.4)	>0.99
Infections	6 (2.2)	2 (2.9)	4 (1.9)
Pseudomeningoceles requiring temporary CSF diversion	2 (0.7)	0 (0.0)	2 (1.0)
Other	1 (0.4)	0 (0.0)	1 (0.5)

CSF diversion = lumbar drain.

Values are expressed as number (%) of patients who underwent the specified procedure. Statistical significance was determined by Fisher’s exact test.
