Key result
Laser Doppler velocimetry detected a significant difference in colostomy blood flow between patients one week post-operatively and those at least nine weeks post-operatively (p < 0.002).
Why the study?
Can laser Doppler velocimetry measure differences in colostomy blood flow between early and late post-operative periods?
Observational (n=18)
Can laser Doppler velocimetry measure differences in colostomy blood flow between early and late post-operative periods?
Laser Doppler velocimetry is a feasible technique for measuring colostomy blood flow and detecting differences based on post-operative time.
Laser Doppler velocimetry detects colostomy perfusion differences by interval; hypothesis-generating and should not yet change practice.
Laser Doppler velocimetry has been used to study colostomy blood flow. Eight patients were studied one week after fashioning of a colostomy and a further ten patients were studied at least nine weeks post-operatively. There was a significant difference in the blood flow between the two groups (p < 0.002). We conclude that laser Doppler velocimetry may be a useful technique for measuring colostomy blood flow.

Billings et al. (1986) conducted an observational in Colostomy (n=18). Laser Doppler velocimetry vs. One week vs at least nine weeks post-operatively was evaluated on Colostomy blood flow (p=<0.002). Laser Doppler velocimetry detected a significant difference in colostomy blood flow between patients one week post-operatively and those at least nine weeks post-operatively (p < 0.002).
