Who would benefit from open abdomen in severe acute pancreatitis?—a matched case-control study

Table 4 Univariate analysis of outcomes in open abdomen and matched control group

	Open abdomen (n = 47)	Matched controls (n = 47)	P
Mortality within 90 days from ICU admission
All patients	20 (43)	8 (17)	0.010
Patients with visceral ischemia *	10 (63)	2 (67)	0.685
Patients without visceral ischemia *	10 (32)	6 (14)	0.066
Patients with abdominal compartment syndrome *^†	19 (48)	3 (14)	0.013
Visceral ischemia	16 (34)	3 (6)	0.002
Necrosectomy within 90 days from ICU admission	26 (55)	10 (21)	0.001
Survivor without necrosectomy ‡	9 (19)	30 (64)	0.004
Time interval between ICU admission and death, median (range), days	13 (0-73)	1 (0-88)	0.138

Number in brackets means percentage unless stated otherwise. Mortality/survival analysis implemented log-rank test. Remaining analysis utilized Fisher’s exact 2-sided test
*Presented is the percentage of patients with the risk factor in question
†Forty open abdomen patients and 21 matched controls suffered from abdominal compartment syndrome
‡Patients that did not undergo necrosectomy and survived 90 days following ICU admission
ICU, intensive care unit
