title: Assessment of anastomotic blood supply by Doppler ultrasound in operations upon the colon.
abstract: Doppler ultrasound was used to determine whether or not colonic anastomoses have sufficient blood supply for healing to occur. Experimental anastomoses placed at, or 1 centimeter from, the last audible arterial signal healed; those placed 2 or 3 centimeters distally had a high incidence of disruption. Results were statistically significant by chi-square analysis, p less than 0.05. Clinical parameters of intestinal viability would not have predicted anastomotic failure.
