Non-operative management for penetrating splenic trauma: how far can we go to save splenic function?

Table 4 Comparison of outcome between treatment groups

	Group 1: Splenectomy (n = 45)	Group 2: Spleen-preserving surgical therapy (n = 51)	Group 3: Non-operative management (n = 22)
Total number of complications	30	21	5
No. of patients with complications	19^a	9^a	4
Ventilation days	1 (0–3)^∞	0 (0–1)	0 (0–0)^∞
ICU stay (days)	2 (0–6)^∞	0 (0–3)	0 (0–1)^∞
Length of hospital stay (days)	8 (7–12)	7 (5–12)	8 (5–15)
Mortality	7^†	0^†	0
