Effect of pre-operative steroid administration on length of stay

Group	LOS without steroids (days) ^*	n	LOS with steroids (days)^*	n	p Value
Endoscopic non-syndromic	1.1 ± 0.3	127	1.0 ± 0.0	9	0.431
Open non-syndromic	3.8 ± 1.3	79	3.7 ± 1.8	29	0.739
Endoscopic syndromic	1.2 ± 0.4	6	2.0 ± 1.4	2	N/A
Open syndromic	3.1 ± 1.0	11	4.6 ± 1.8	5	N/A

Level of significance: 0.0253. P values for the syndromic groups are not given as these results would be underpowered.

Values expressed as means ± one standard deviation.

LOS = length of stay.
