Predicting the outcome of closed-loop small bowel obstruction by preoperative characteristics

Table 7 Intervals between onset of symptoms and computed tomography and surgery in the three study groups

Intervals	Viable bowel, n = 28	Reversible ischemia, n = 86	Irreversible ischemia, n = 34	P value
Onset of symptoms to CT, median (range)	16.50 h (2.00–120.00 h)	20.50 h (1.00–260.00 h)	18.00 h (2.00–120.00 h)	0.79
CT to surgery, median (range)	4.00 h (1.00–65.00 h)	4.00 h (1.00–51.00 h)	4.00 h (1.00–71.00 h)	0.98
Onset of symptoms to surgery, median (range)	23.00 h (3.00–124.00 h)	26.00 h (2.00–264.00 h)	25.50 h (5.00–126.00 h)	0.91
