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

Published: 30th September 2017

Authors: Donal P, Peirce C, Anglim B, Burton M, Concannon E, Carter M et al.

Conclusion

Fifty patients were included. Use of the negative pressure dressing reduced the risk of surgical site infection at 30 days (8.3 versus 32 per cent, P=0.043) and speeded hospital discharge: median 6.1 versus 14.7 days, P=0.019.
