Clinical investigation of 41 patients with ischemic colitis accompanied by ulcer

Table 1 Clinical features of ischemic colitis patients: Comparison between ulcer and non-ulcer groups (mean ± SD)

Clinical features	Ulcer group (n = 9)	Non-ulcer group (n = 32)	Statistical significance
Age (mean, range, yr)	68 ± 19 (35-87)	71 ± 11 (42-92)	NS
Percentage of females (%)	77.8	75.0	NS
Lesion location: left colon (%)	88.9	100	NS
Performance status 0-1 (%)	77.8	87.5	NS
WBC (× 109/L)	12.27 ± 4.67	8.44 ± 3.17	P = 0.0065
CRP (mg/dL)	2.6 ± 4.1	1.5 ± 2.3	NS
K (mEq/L)	3.8 ± 0.4	4.0 ± 0.5	NS
Total cholesterol (mg/dL)	179.3 ± 30.6	191.4 ± 35.6	NS
TG (mg/dL)	93.3 ± 41.0	73.2 ± 23.4	NS
LDH (IU/L)	190.0 ± 42.8	203.8 ± 37.8	NS
CPK (IU/L)	80.7 ± 38.9	82.7 ± 39.5	NS

Percentage of females and lesion location were evaluated with an χ-square test; Other data were evaluated with Student’s t test after skewing with log transformation. CRP: C-reactive protein; K: potassium; TG: triglyceride; LDH: lactate dehydrogenase; CPK: creatinine phosphokinase.
