Table 2. Arterial Blood Flow by Doppler Probe for Definitive vs. Presumptive Diverticular Hemorrhage.

*p < 0.05. + DEP is positive Doppler endoscopic probe signal for arterial blood flow. SRH are stigmata of recent hemorrhage. NBVV is non-bleeding. TIC is diverticular (bleed). See references (18, 20)
