Early colonoscopy and urgent contrast enhanced computed tomography for colonic diverticular bleeding reduces risk of rebleeding

Table 9 Relationship between detection of stigmata of recent hemorrhage and contrast-enhanced computed tomography examination

	All cases		Urgent CT group (≤ 4 h)		Elective CT group (> 4 h)
	Extravasation-positive	Extravasation-negative	Extravasation-positive	Extravasation-negative	Extravasation-positive	Extravasation-negative
SRH-positive	35	6	31	4	4	2
SRH-negative	32	109	16	49	16	60
SRH identification rate (%)	52.2 (35/67)	5.2 (6/115)	66.0 (31/47)	7.5 (4/53)	20.0 (4/20)	3.2 (2/62)
P value			< 0.01

P value: Urgent CT group (extravasation-positive) vs Elective CT group (extravasation-positive). SRH: Stigmata of recent hemorrhage; CT: Computed tomography.
