Prophylactic negative pressure dressing use in closed laparotomy wounds following abdominal operations: a randomized, controlled, open-label trial: the PICO Trial. Ann Surg 2017; 265: 1082-1086.

Published: 28th November 2017

Authors: O’Leary DP, Pierce C, Anglim B, Burton M, Concannon E, Carter M et al.

Conclusion

Fifty patients having a laparotomy were included. Negative pressure dressing reduced the rate of surgical site infection after 30 days from 32 to 8.3 per cent, P=0.043, and duration of hospital stay: 6.1 versus 14.7 days, P=0.019.
