Abstract
Purpose
The efficacy of closed-suction drainage in primary intradural spinal cord tumor surgery has not been addressed. We investigated whether closed-suction drainage is essential after primary intradural spinal cord tumor surgery.
Methods
From January 2003 to October 2011, 169 consecutive patients with primary intradural spinal cord tumors operated by a single surgeon were selected. Closed-suction drainage was inserted in patients before August 2007, but was not used after August 2007. After removal of tumor and meticulous hemostasis, the opened dura was closed and made watertight using 4-0 silk with interrupt suture and 1.0 cm3 of surgical glue was applied in common. Closed-suction drainage was inserted below the muscular fascia in 75 patients (group I, M:F = 39:36; 46.20 ± 15.63 years) and was not inserted in 94 patients (group II, M:F = 46:48; 51.05 ± 14.89 years).
Results
Neurological deficit precluding ambulation did not occur in all patients. Between group I and II, there were no significant differences in body mass index (22.75 ± 3.16 vs. 23.51 ± 3.22 kg/m2; p = 0.13), laminectomy level (2.45 ± 1.46 vs. 2.33 ± 1.91; p = 0.65), operation time (260.65 ± 109.08 vs. 231.52 ± 90.08 min; p = 0.06), estimated intraoperative blood loss (456.93 ± 406.62 vs. 383.94 ± 257.25 cm3; p = 0.18), and hospital stay period (9.25 ± 5.01 vs. 9.35 ± 5.75 days; p = 0.91). Two patients in group I underwent revision surgery due to wound problems, while revision surgery was not performed in group II (p = 0.20).
Conclusion
Closed-suction drainage may not be essential after primary intradural spinal cord tumor surgery.
